Answer 1

Answer:

F. 1080

Step-by-step explanation:

Just like any shape, we get to do base x height! If you haven't located the base yet it's the right triangles. So first we have to find the area of the triangle and then multiply by the height (20). Lets find the area of the triangle first. To get the area you do (length x width)/2. 9*12/2=54. Now 54*20=1080

1/10x+9/10=1/10(BLANK)

Answers

Answer:

x=-8

Step-by-step explanation:

1 Simplify 1/10x to x/10.

x/10 + 9/10 = 1/10

2 Join the denominators.

x+9/10 = 1/10

3 Multiply both sides by 10.

x+9 = 1/10×10

4 Cancel 10.

x+9=1

5 Subtract 9 from both sides.

x=1-9

6 Simplify  1-9 to  -8.

x=-8

Which equation is modeled by the data in the table?​

Answers

Answer:

Step-by-step explanation:

In order to get to the correct answer here, you should plug in each of the x-values from the table into all four equations presented in the answer choices to see which one equals all of the y-values.

When you do this and plug each x-value from the table into the answer choices, option C leads you to getting all of the correct y-values.

So the correct answer choice here is option C, y=5x+3

Answer:

the equation modeled by data table is

y = 5x + 3

Solve the following systems using the elimination method.

4x + 7y = 19

Answers

Answer: x = -4, y = 5

Step-by-step explanation:

[tex]$$Solve the following system: \\$\left\{\begin{array}{ll}7 y+4 x=19 & \text { (equation 1) } \\ -y+2 x=-13\end{array} \quad\right.$ (equation 2)\\\\Subtract $\frac{1}{2} \times($ equation 1) from equation 2 :\\$\left\{\begin{array}{l}4 x+7 y=19 \ \ \ \ (\text{equation 1}) \\ 0 x-\frac{9 y}{2}=-\frac{45}{2}\end{array}\right.$ (equation 2)\\\\Multiply equation 2 by $-\frac{2}{9}$ :\\[/tex]

[tex]\begin{cases}4 x+7 y=19 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Subtract $7 \times($ equation 2) from equation 1:\\$\begin{cases}4 x+0 y=-16 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2)\\ }\end{cases}$\\\\Divide equation 1 by 4 :\\$\begin{cases}x+0 y=-4 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Answer:\\$$\left\{\begin{array}{l}x=-4 \\y=5\end{array}\right.$$[/tex]

Answer: x = -4, y = 5

Step-by-Step Explanation:

=> 4x + 7y = 19 (Eq. 1)
=> 2x - y = -13 (Eq. 2)

We can multiply Eq. 2 by 7 in order to make the coefficients of ‘y’ same in both the equations thus being able to eliminate ‘y’ and find ‘x’

Therefore,
(2x - y = -13) * 7
=> 14x - 7y = -91 (Eq. 3)

On Adding Eq. 1 and 3, we get :-

18x = -72 (‘y’ gets Eliminated)
x = -72/18
=> x = -4

Therefore, x = -4

Substitute value of ‘x’ in Eq. 2 :-

2x - y = -13
2(-4) - y = -13
-8 - y = -13
-y = -13 + 8
-y = -5
=> y = 5

Therefore, y = 5
