Answer:
x^2-2x-13
Step-by-step explanation:
f(x) = 2x-5
g(x) = x^2 -4x-8
f(x) +g(x) = 2x-5 + x^2 -4x-8
Combine like terms
= x^2+2x-4x-5-8
=x^2-2x-13
Answer:
a = 5/6 , b = -3/10
Step-by-step explanation:
3a-5b:3a+5b=1:4
3a-5b / 3a +5b = 1/4
Cross multiply
3a -5b =4 ..........(1) solve simultaneously
3a + 5b = 1 ..........(2) using elimination method
-----------------------
Add equation 1 and 2
6a = 5
Divide both sides by 6
6a/6 = 5/6
a =5/6
Put value of a into equation 2
3a +5b = 1
3(5/6) + 5b = 1
5/2 + 5b = 1
5b = 1 - 5/2
5b = - 1½
5b = - 3/2
Divide both sides by 5
5b/ 5 = -3/2 ÷ 5
b = -3/2 × ¹/5
b = - 3/10
Therefore a = 5/6 , b = -3/10

F is 4/2. i did the i-ready, hope this helps
Removing the outlier changes all the measures except the mode.
The mode changes least.
<h2>Answer:</h2><h3><em>
y = -1x - 9</em></h3><h2>Explanation:</h2>
First, we’ll need to find the <u>slope</u>.
(-5,-4) (-2,-7)
m = 
m = 
m = 
m = -1
Next, substitute these values into the <u>point slope equation:</u>
y - 
= m(x - 
)
y - (-7) = -1(x - (-2))
y + 7 = -1(x + 2)
Now, convert to <u>slope intercept form (y = mx + b):</u>
y + 7 = -1x -2
-7 -7
y = -1x - 9
