Step-by-step explanation:
y = 4x-1
2x+y = 5
2x+(4x-1) = 5
6x - 1 = 5
6x = 6
x = 1
Answer:
(1,3)
Step-by-step explanation:
Since we already have the variable to it self, we can substitute y=4x-1 into 2x+y=5.
So it would be 2x+(4x-1)=5
Remove the parentheses
Combine like terms
Move the constant to the right
Divide 6 on both sides to get the variable by it self.
x=1
Then we substitute x=1 into y=4x-1, so..
y=4(1)-1
y=4-1
y=3
So the answer would be (1,3).

A figure has an area of 64 square units. Which describes the area of the figure after a dilation with a scale factor of 3/2?
A)96 square units
B)144 square units
C)112 square units
D)32 square units
Compare multiplying a number by 3 and by 1 third. *
Answer:
Multyplying by 1 third is the same as dividing by 3, so it's the opposite as multiplying by 3.
Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
f(x) = -x + 8
g(x) = x2 – 3x+2
Answer:
(gof)(-8) = 210
Step-by-step explanation:
(gof) = (-x + 8)² - 3(-x + 8) = 2
= x² - 16x + 64 + 3x - 24 + 2
= x² - 13x + 42
(gof)(-8) = (-8)² - 13(-8) + 42
= 64 + 104 + 42
= 210

Work out 3/5 of 900
Answer:
540
Step-by-step explanation:
1. We assume, that the number 900 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 900 is 100%, so we can write it down as 900=100%.
4. We know, that x is 3.5% of the output value, so we can write it down as x=3.5%.
5. Now we have two simple equations:
1) 900=100%
2) x=3.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
900/x=100%/3.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 3.5% of 900
900/x=100/3.5
(900/x)*x=(100/3.5)*x - we multiply both sides of the equation by x
900=28.571428571429*x - we divide both sides of the equation by (28.571428571429) to get x
900/28.571428571429=x
31.5=x
x=31.5
now we have:
3.5% of 900=31.5
