Answer 1

Answer:

x = 8

Step-by-step explanation:

In a triangle, if two angles are congruent, then the opposite sides are congruent.

Since you are told that angles A and C are congruent, then their opposite sides, BC and AB are congruent.

That makes BC = AB.

3x - 3 = 2x + 5

x = 8

Answer 2
If angle A = angle C, line AB = line BC

2x + 5 = 3x - 3
+3
2x + 8 = 3x
-2x
8 = x
Answer
x = 8

If C = q^2-2+q and D = 3q^2+2q, find an expression that equals 3C - 3D in standard form.
Please help ;-;

Answers

Answer:

- 9q² - 3q - 6

Step-by-step explanation:

3C - 3D

= 3(q² - 2 + q) - 3(3q² + 2q) ← distribute parenthesis

= 3q² - 6 + 3q - 9q² - 6q ← collect like terms

= - 9q² - 3q - 6

The required expression is - 9q² - 3q - 6 which equals 3C - 3D in standard form.

What is the expression?

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given in the question as follows:

3C - 3D  ....(i)

We have to determine the resultant expression that could represent the standard form.

As per the question, we have the equations

C = q² - 2 + q and D = 3q² + 2q

Substitute these equations into the expression (i):

3(q² - 2 + q) - 3(3q² + 2q)

Apply the distributive property of multiplication,

3q² - 6 + 3q - 9q² - 6q

Combine the likewise terms in the above expression,

- 9q² - 3q - 6

Thus, the resultant expression is - 9q² - 3q - 6.

Answer:

2x - 7y = -34.

Step-by-step explanation:

As the line we want is perpendicular to y= -7/2 x + 9 it's slope will be

-1 /(-7/2) = 2/7.

Now we find the point of intersection ofn the 2 given  lines:

x    + y = 10

3x - 4y = -12

Multiply the first equation by -3:

-3x - 3y = -30

Now add this last equation to the second one:

-7y =  -42

y = 6

Plug y = 6 into the first equation:

x + 6 = 10

x = 4.

So the point of intersection is (4, 6) and the equation we want passes through this, so using the point-slope form of  straight line we have:

y - 6 = 2/7(x - 4)

7y - 42 = 2(x - 4)

7y - 42 = 2x - 8

2x - 7y = -42 + 8

2x - 7y = -34

Answer:

y=(2/7)x+(7/3)

Step-by-step explanation:

y=-7/2(x)+9

y=mx+c

Therefore, slope of line y is -7/2

Because line y perpendicular to the required line

Therefore, slope of the required line is 2/7

x+y=10 ........(1)

3x-4y = -12 ......(2)

(1) x 4:

4x+4y =40 ......(3)

(3) + (2)

4x+4y+3x-4y=28

x=4

by substituting x=4 into (1), we have

y=10-4=6

Therefore, the point that the line intersects is (4, 6)

let y=(2/7)x+c be the required equation

(4, 6):

6=(2/7)4+c

c=21/4

therefore, the required equation is y=(2/7)x+(7/3).

Using the pattern, give the coefficients of (x + y)^5 and (x + y)^6

Sign up now and get 12 months for just 16 dollars and 99 cents per month asterisk. The asterisk is given as paid in advance.

Answers

Answer:

No, this is not a correct amount. The correct amount is $203.88

Step-by-step explanation:

The computation of the credit card amount is shown below:

Given that

The credit card is $220.87

But if we calculate the credit card amount, so it would be

= 12 months × 16.99

= $203.88

hence, the credit amount is $203.88

And, the given amount is wrong

So, the correct amount is $203.88

Miranda is renovating her home and needs a $32,000 loan to pay for the renovations. The bank offers her a 4.8% annual compound interest rate if she pays it off in 3 to 5 years. How much more would Miranda pay for the 5 year loan than the 3 year loan?

Answers

Answer:

$3072

Step-by-step explanation:

The compound interest formula for the amount paid on the loan P = P₀(1 + rt/100) where P₀ = loan amount = $32,000, r = rate = 4.8 % per annum and t = time

For the 3 year loan, t = 3, So,

P = P₀(1 + rt/100)

P = $32,000(1 + 4.8 × 3/100)

P = $32,000(1 + 14.4/100)

P = $32,000(1 + 0.144)

P = $32,000(1.144)

P = $36608

For the 5 year loan, t = 5, So,

P' = P₀(1 + rt/100)

P' = $32,000(1 + 4.8 × 5/100)

P' = $32,000(1 + 24/100)

P' = $32,000(1 + 0.24)

P' = $32,000(1.24)

P' = $39680

So, the amount more Miranda pay for the 5 year loan than the 3 year loan is P' - P = $39680 - $36608 = $3072

In 3 years Miranda would pay $36,832.72.

In 5 years Miranda would pay $40,453.53.

13. Yes, these side lengths can form a triangle.

-- 4 + 5 = 9.

-- 9 is greater than 7, the largest length.

14. No, these side lengths can't form a triangle.

-- 2 + 3 = 6

-- 6 is equal to 6, not greater than.

15. Yes, these side lengths can form a triangle.

-- 2 + 4 = 6

-- 6 is greater than 5, the largest number.

16. Yes, these side lengths can form a triangle.

-- Don't get confused when you see that there are two side lengths that are the same (it means that this is an isosceles triangle); the rules still apply.

-- 2 + 8 = 10

-- 10 is greater than 8, the largest number.

17. Yes, these side lengths can form a triangle.

-- 5 + 6 = 11

-- 11 is greater than 9, the largest number.

18. Yes, these side lengths can form a triangle.

1 Asalesman leaves home at 0800 and travels for 13 hours at an average
speed of 60km/h. He then stops for 30 minutes. He continues for 2 more
hours at 50km/h and stops for 1 hour. He then returns home and arrives
home at 1600.

a) Show this in a travel graph.
b) Calculate his average speed for his return journey.

Answers

Answer:

a) Please find attached the required travel graph with times increasing from (0:00) of the day of travel to the following day

b) The average speed of return journey = 880 km/(15.5 h) ≈ 56.77 km/h

Step-by-step explanation:

The given information includes;

The time of departure of the salesman, t₁ = 0800

The duration of travel of the salesman = 13 hours

The average speed with which the salesman travels = 60 km/h

The time duration in which he stops = 30 minutes

The speed with which he continues = 50 km/h

The time duration he travels at 50 km/h = 2 hours

The time he arrives home after he turns, t₂ = 16:00

The appropriate graph is a distance time graph

So as to show the given information in a travel graph, we calculate the distances as follows;

Time   [tex]{}[/tex]                                                                     Location

08:00   [tex]{}[/tex]                                                                   0

08:00 + 13 = 21:00  [tex]{}[/tex]                                                13 × 60 = 780

21:00 + 0.30 = 21:30  [tex]{}[/tex]                                             780

21:30 + 2:00 = 23:30  [tex]{}[/tex]                                            780 + 50 × 2 = 880

23:30 + 1:00 = 0:30 (24: hours )   [tex]{}[/tex]                          880

16:00  [tex]{}[/tex](40 hours from 0:00 the previous day)  

Therefore, we have;

Location; 0, 780, 780, 880, 880, 0

Time; 08:00, 21:00, 21:30, 23:30, 24:30, 40:00

To show the distance traveled over the given time periods graphically, we let 00:30 = 24.30 and the arrival time (the next day) 16:00 = 40.00 hours after midnight (0:00) the previous day                

Please find attached the required travel graph created with Microsoft Excel

b) The average speed of return journey = (Total distance of return journey)/(Total time)

The total distance going = 880 km

Therefore the return journey is also 880 km

∴ The total time taken on return journey Δt = (Time at arrival home) - (Time of start of return journey)

∴ Δt = 40 - 24.5 = 15.5

Δt = 15.5 hour

∴ The average speed of return journey = 880 km/(15.5 h) ≈ 56.77 km/h.

The focus of a parabola is (-4, -5), and its directrix is y = -1. What is the formula for the parabola in standard form.

Answers

Answer:

[tex](x - (-4))^2 = -8(y - (-3))[/tex]

[tex]Where\ p<0[/tex]

Step-by-step explanation:

From the question we are told that:

Parabola  focus co-ordinates

[tex]F=(-4, -5)\\Directrix is y = -1[/tex]

Generally the equation for standard form of Parabola is mathematically given by

[tex](x - h)^2 = 4p(y - k)[/tex]

where p≠ 0

Generally the equation for Directrix of Parabola is mathematically given by

[tex]y=k-p\\y=-1[/tex]

Generally the equation for Focus of Parabola F is mathematically given by

[tex]F=(h, k + p).[/tex]

[tex]F=(-4, -5)[/tex]

Therefore

[tex]k-p=-1[/tex]

[tex]k=-1+p[/tex]

Given

[tex]k+p=-5[/tex]

[tex]-1+p+p=-5[/tex]

[tex]2p=-4[/tex]

[tex]p=-2[/tex]

Therefore

[tex]k-p=-1[/tex]

[tex]k-(-2)=-1[/tex]

[tex]k=-3[/tex]

Generally the equation for standard form of Parabola is mathematically given by

[tex](x - (-4))^2 = 4(-2)(y - (-3))[/tex]

A: 1/6
B: 2/3
C: 5/6

[tex]L = \frac 14[/tex] ----- The left over

[tex]F = \frac 23[/tex]  ----- The fraction eaten by Leroy's brother

The fraction of the whole cake (B) eaten by Leroy's brother is:

[tex]B = L \times F[/tex]

So, we have:

[tex]B = \frac 14 \times \frac 23[/tex]

Cancel out common terns

[tex]B = \frac 12 \times \frac 13[/tex]
