Answer:
vertex is (4,-25)
Step-by-step explanation:
To find out the vertex we use formula
From the given f(x), the value of a=1, b=-8 and c=-9
Plug in the values in the formula
x=4
Now find the value of y
plug in 4 for x in f(x)
The value of y is -25
The vertex is (4,-25)
Answer:
B
Step-by-step explanation:
Recommended for housing: 30%
X/100 = 612/1700
= 36%
Recommended for food: 10%
X/100 = 238/1700
= 14%
Recommended for transportation 15%
X/100 = 370/1700
= 21.8%
7*11=77 because 7 and 11 are 4 apart Enjoy!=)
Let's solve for x --
Isn't it always a little easier to solve a math problem with starting by rewriting the equation?
3/8x + 15/2 = 8
Step 1) Subtract 15/2 from both sides
3/8x + 15/2 - 15/2 = 8 - 15/2
3/8x = 1/2
Step 2) Multiply both sides by 8/3
(8/3) × (3/8x) = (8/3) × (1/2)
x = 4/3
FINAL ANSWER -
x = 4/3

Ok so you would start by getting rid of the fraction. You should know the steps for that by now but here this is what it would look like
3y/4+10=2y/4 Simplify
3y/4+10=1y/210=-1y I really simplified the last part but this is what it looks like:
- 
= -1y
10=-1yy=-10
