Answer: x=3
Step-by-step explanation:
4(2x-7)-2x=-10
Multiply 4 with 2x and -7
8x-28-2x=-10
Add like terms which are 8x and -2x
6x-28=-10
Add 28 to both sides so the -28 cancels out
6x=18
Divide both sides by 6 to isolate the x
Answer= x=3
Q1. The answer is 100 hours
10 ml is for 1 hours
1l is for x hours
1l = 1000 ml
So, make a proportion:
10 ml is for 1 hours
1000 ml is for x
10 ml : 1h = 1000 ml : x
x = 1h * 1000 ml : 10 ml = 100 hours
Q2. The answers are:
1. kg - measurement of mass
2. cm² - measurement of area
3. L - measurement of volume (1L = 1 dm³)
4. m - measurement of length
First box’s is angle addition postulate. The the second box is x=15
Answer:
{-1, 4}
Step-by-step explanation:
In the given f(x) = -1/2x^2 + 3/2x - 2
set f(x) = 0 and then multiply all the numeric terms by -2 to remove the fractions:
f(x) = -1/2x^2 + 3/2x - 2 = 0 => 1x^2 - 3x - 4 = 0
This factors into (x - 4)(x + 1) = 0, whose roots are {-1, 4}. These are the zeros.

Answer: B) 6 right and 9 down</h3>
We start with x-5. We want to add on some h value such that x-5+h = x+1, which solves to h = 6. So we must add on 6 to (x-5) to get to (x+1). This shifts the graph 6 units to the right.
As for the vertical shifting, we start with +7 and we end up at -2. The vertical distance is 7-(-2) = 9 units, so we must shift 9 units down.
