Answer:
~30
Step-by-step explanation:
By using division, the answer is 29.34. If the question is asking to estimate, I would estimate the quotient as 30.
<span>hello :
اthe vertex of the absolute value function defined by ƒ(x) = |x + 5| + 7 is :

<em><u>Question:</u></em>
4x + 2y = 0
- 4x – 9y= - 28
Solve each system by elimination
<em><u>Answer:</u></em>
The solution is x = -2 and y = 4
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
4x + 2y = 0 ------ eqn 1
-4x – 9y = - 28 ------- eqn 2
We have to solve the system of equations by elimination method
Add eqn 1 and eqn 2
4x + 2y -4x -9y = 0 - 28
0 + 2y - 9y = -28
-7y = -28
Divide both sides by -7
y = 4
<em><u>Substitute y = 4 in eqn 1</u></em>
4x + 2(4) = 0
4x + 8 = 0
4x = -8
Divide both sides by 4
x = -2
Thus the solution is x = -2 and y = 4
Answer:
the answer to #9 is (½, 1½)
Step-by-step explanation:
to find the midpoint, you need to use the midpoint formula
the midpoint formula is (x₁ + x₂ / 2 , y₁ + y₂ / 2)
for #9 you have to plug in the appropriate numbers in the formula
(-4 + 5 / 2 , 4 - 1 / 2)
(½ , 1½)
