Solve the system of equations by substitution. * -8x + 2y = 4 y = 4x + 2 ​

Answer:

(A)

Step-by-step explanation:

Well you gotta isolate the variable by perfoming inverse operations so you gotta dd 70 to both sides.

Answer: $21.25

Step-by-step explanation:

Given

Lynnette purchased 2.5 Pounds of blent, which costs $8.50 per pound

total cost is the Product of the amount of blend and rate of coffee blend

[tex]\Rightarrow C=2.5\times 8.50=\$21.25[/tex]

So, coffee beans cost $21.25

Answer:

9 units

Step-by-step explanation:

Given: Two points on a coordinate plane are [tex](-5,9),\,(4,9)[/tex]

To find: distance between points [tex](-5,9),\,(4,9)[/tex]

Solution:

According to the distance formula,

Distance between points [tex](a,b)[/tex] and [tex](c,d)[/tex] is equal to [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]

Take [tex](a,b)=(-5,9),\,(c,d)=(4,9)[/tex]

Therefore,

Distance between points [tex](-5,9),\,(4,9)[/tex] [tex]=\sqrt{(4+5)^2+(9-9)^2}[/tex]

                                                               [tex]=\sqrt{(9)^2}[/tex]

                                                               [tex]=9[/tex] units

Answer: The number of dogs in all of the city's animal shelters is puppies = 270

Step-by-step explanation:

Given: A random sample of dogs at different animal shelters in a city shows that 10 of the 55 dogs are puppies.

The city's animal shelters collectively house 1,485 dogs each year.

The number of dogs in all of the city's animal shelters is puppies = [tex]1485\times\dfrac{10}{55}=270[/tex]

Hence, The number of dogs in all of the city's animal shelters is puppies = 270

Answer:

Unlikely = greater Than 0 ; less than

Likely = greater than 0.5 ; less than 1

Neither likely nor unlikely = 0.5

Step-by-step explanation:

Probability values usually range between standardized values between 0 and 1. With values closer to 1 depicting greater possibilities of an event. Probability value of zero means certain and probability value of 0 zero means.impossible.

Using this standardized values :

An unlikely event is more of not occurring than occurring (that is the event has higher chances of not happening) ;

Hence; We can categorize unliky events to range from below the mid value to greater Tha.n 0

Unlikely event : greater Than 0 ; less than 0.6

Events with probability above the mid value of 0.5 have higher chances of occurring (greater likelihood) hence, Probability is greater than 0.5 but less than 1.

Neither likely nor unlikely event will take the boundary point between likely and unlikely = 0.5

Answer:

0.7 km per minute , -0.17 km per minute

Step-by-step explanation:

The computation of the average speed is shown below

As we know that

Average speed = Total distance ÷ total time

= (4 + 2 + 1) ÷ (32 + 22 + 16)

= 0.7 km per minute

Now the velocity is

= Change in displacement ÷ change in time

= (4 - 2 - 1) ÷ (32 -22 -16)

= 1 ÷ -6

= - 0.17km per minute

Answer: 5n = 35

Step-by-step explanation:

The product of a number n and the number 5 is 35. This statement can be formed into an equation as:

n × 5 = 35

5n = 35

The equation is 5n = 35

If we want to get the value of the number, it'll be:

5n = 35

n = 35/5

n = 7

The number is 7

Answer:

[tex]y+21 = -4(x-7)[/tex]

Step-by-step explanation:

1) First, find the slope of the line between the two points. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (7, -21) and (-4, 23) into the formula and simplify:

[tex]m = \frac{(23)-(-21)}{(-4)-(7)} \\m = \frac{23+21}{-4-7}\\m = \frac{44}{-11}\\m = -4[/tex]  

So, the slope of the line is -4.

2) Now we have all the information we need. To write the equation of the line, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].

Since [tex]m[/tex] represents the slope, substitute -4 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, substitute the x and y values of (7, -21) into the equation as well. This gives the following answer:

[tex]y+21 = -4(x-7)[/tex]  

Answer:

13. Option 3

14.Option 2

Step-by-step explanation:

Option 3 shows that caleb has $5 or less by using the "less than or equal to" sign

Option 2 uses a closed circle to show that $5 is included in the table.

Things to remember that helped me

Closed circle are used for < and > signs to show that the number is being included. They mean "less than or equal to (<)" and "more than or equal to(>)"

Open circles are used for < and > signs. To show that the number is NOT included in the inequality.

Also when looking at the signs < and >, Picture them as arrows. That will show you the direction on the number line they go. For example < is pointing to the left which would mean "LESS THAN" and same with >, its pointing to the right which would mean "MORE THAN"

Answer:

$ 825

Step-by-step explanation:

10 yard = $150

55yard = ?

55yard* $150 /10yard

55*15 =825 then the correct answer of

$55 yard is 825

519.99(.0825) = 42.899

519.99 + 42.899 = $562.89

Answer:

Sales tax---> 553.98 x 0.075= 41.5485

Total---> 553.98 + 41.5485= 595.5285

Round to nearest tenth---> 595.53 is your answer

Answer:

F = [tex]\frac{9}{5}[/tex] C + 32

Step-by-step explanation:

Given

C = [tex]\frac{5}{9}[/tex] (F - 32)

Multiply both sides by [tex]\frac{9}{5}[/tex] to clear the fraction

[tex]\frac{9}{5}[/tex] C = F - 32 ( add 32 to both sides )

[tex]\frac{9}{5}[/tex] C + 32 = F

9514 1404 393

Answer:

Step-by-step explanation:

The coefficient is the initial amount: $15.35.

The growth factor is the base of the exponential term: 1.0279. The growth rate is 1 less than this: 1.0279 -1 = 0.0279 = 2.79%. It is positive, so represents a growth of 2.79% per day.
