what is the algebraic expression of three fourths the square of b

Answer:

slower car=60 miles/hr

faster car =80 miles/hr

Step-by-step explanation:

the speed of slower car =x

the speed of faster car=x+20

they both 210 miles apart

(x+x+20)*(1 1/2 )=210

(2x+20)(3/2)=210

3x+30=210

3x=210-30

3x=180

x=180/3 ⇒ x=60

x+20 ⇒ 60+20=80

Answer:

[tex]6{x}^{2} - 2x + 4 - 12x =6 {x }^{2} - 14x + 4[/tex]

The simplified expression of 2x(3x - 1) + 4(1 - 3x) is 6x² + 4 - 14x

From the question, we have the following parameters that can be used in our computation:

2x(3x - 1) + 4(1 - 3x)

When the brackets are opened, we have

2x(3x - 1) + 4(1 - 3x) = 6x² - 2x + 4 - 12x

Evaluate the like terms

so, we have the following representation

2x(3x - 1) + 4(1 - 3x) = 6x² + 4 - 14x

Hence, the simplified expression is 6x² + 4 - 14x

Step-by-step explanation:

[tex]-\frac{-32-\left(-16\right)}{8}=2\\x=2\\x=2,\:y=-16[/tex]

Answer:

x = 2

y = -16

Step-by-step explanation:

Substitute value of y, -3x - 10 in the equation-8x + y = -32

-8x + (-3x - 10) = -32

-8x - 3x - 10 = -32

-11x - 10 = -32

-11x = -32 + 10

-11x = -22

Divide both sides by coefficient of x which is -11

x = 2

Substitute value of x, 2, in the equation-3x - 10 = y

(-3)2 - 10 = y

-6 - 10 = y

y = -16

Answer:

Kyra is correct.

Step-by-step explanation:

Rational numbers;

All numbers which can be written in the form of [tex]\frac{p}{q}[/tex] are rational numbers.

Example: 1, 2, [tex]\frac{1}{2}[/tex], 1.414141....

Irrational numbers:

Numbers which are not in the form of [tex]\frac{p}{q}[/tex] are irrational.

Example: 1.234, π, √2

So rational and irrational numbers are two separate things.

But all positive and negative numbers are real numbers.

Real numbers may be rational or irrational both.

Therefore, Kyra's interpretation is correct.  

Answer:

with what part of the question be more specific

Answer:

Step-by-step explanation:

If points A, B and C are collinear, then A, B and C lies on the same straight line. Hence AB+BC = AC

Given

AB = 12''

BC = 8''

To get length od segment AC, we will substitute the given values into the formula above as shown;

AB+BC = AC

12 + 8 =AC

AC = 12+ 8

AC = 20''

Hence the length of AC is 20''

Answer:

j(x) is an odd function

Step-by-step explanation:

We are given;

j(x) = 220/x³ and j(-x) = 220/(-x)³

Now,

when x = 1;

j(x) = 220/1³ = 220/1 = 220

j(-x) = 220/(-1)³ = 220/-1 = -220

When x = 2;

j(2) = 220/2³ = 220/8

j(-2) = 220/(-2)³ = -220/8

Now, Algebraically, function j would be even if and only if j(-x) = j(x) for all x in the domain of j. While j is odd if and only if j(-x) = -j(x) for all x in the domain of j.

From the values gotten, we can see that :j(-x) = -j(x). Thus, we can say that j(x) is an odd function.

Answer:

A) j(x) is an odd function.

Step-by-step explanation:

[tex] \sf{ - (1 + 7x) - 6( - 7 - x) = 36}[/tex]

Distribute ( - ) sign through the parentheses

Similarly, distribute -6 through the parentheses

[tex] \dashrightarrow{ \sf{ - 1 - 7x + 42 + 6x = 36}}[/tex]

Collect like terms

[tex] \dashrightarrow \sf - 7x + 6x - 1 + 42 = 36[/tex]

[tex] \dashrightarrow \: \sf \: - x - 1 + 42 = 36[/tex]

The negative and positive integers are always subtracted but possess the sign of the bigger integer

[tex] \dashrightarrow{ \sf{ - x + 41 = 36}}[/tex]

Move 41 to right hand side and change it's sign

[tex] \dashrightarrow{\sf{- x = 36 - 41}}[/tex]

Change the signs on both sides of the equation

Answer:

angle 1 = 60 degrees

angle 2 = 120 degrees

=====================================================

Explanation:

Supplementary angles always add to 180 degrees. In other words, the two angles form a straight line.

(angle1) + (angle2) = 180

4x+8x = 180

12x = 180

12x/12 = 180/12 .... dividing both sides by 12

x = 15

Use this x value to find the two angle measures

angle1 = 4x = 4*15 = 60

angle2 = 8x = 8*15 = 120

As a check, angle1+angle2 = 60+120 = 180, which confirms our answer.

Answer:

B. 2x + $22 = $56 ; x = $17

Step-by-step explanation:

Assuming a pair of short is accounted for by the variable x.

Your total cost is $56. This means that your expression will equal 56:

________________ = 56

Next, you buy 1 shirt (denoted by s) for $22.

s = $22

You buy 2 pairs of pants. The cost is not given, so it can vary. Give it a variable. The answers denote it as x. As you are buying two pairs of pants, multiply 2 with x:

2 * x = 2x.

Combine the terms and plug it into the equation:

2x + 22 = 56

Next, solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Remember,  PEMDAS is the order of operation, &

PEMDAS =

Parenthesis

Exponents & Roots

Multiplication

Division

Addition

Subtraction

First subtract 22 from both sides:

2x + 22 (-22) = 56 (-22)

2x = 56 - 22

2x = 34

Next, divide 2 from both sides:

(2x)/2 = (34)/2

x = 34/2

x = $17

B. 2x + $22 = $56 ; x = $17 is your answer.

Answer:

d = 4

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₁ = - 2 and a₈ = 26 , then

- 2 + 7d = 26 ( add 2 to both sides (

7d = 28 ( divide both sides by 7 )

d = 4

Answer:

d = 4

Step-by-step explanation:

a₁ = -2

a₈ = aₙ = 26

n = 8

aₙ = a₁ + d(n-1)

d = aₙ - a₁ / (n-1)

d = 26 -(-2) / (8-1)

d = 26 + 2 / 7

d = 28 / 7

d = 4

-2

-2 + 4 = 2

2 + 4 = 6

6 + 4 = 10

10 + 4 = 14

14 + 4 = 18

18 + 4 = 22

22 + 4 = 26

Answer:

18 muffins

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=34 (1)

0.50x+0.75y=21 (2)

where x is the number of muffins and y is the number of bagels.

First, you can isolate x in (1):

x=34-y (3)

Then, you can replace (3) in (2):

0.50(34-y)+0.75y=21

17-0.5y+0.75y=21

0.25y=21-17

0.25y=4

y=4/0.25

y=16

Now you can replace the value of "y" in (3):

x=34-16

x=18

According to this, the answer is that you sold 18 muffins.
