Answer:
<h2>The range: {0, 10, 42}</h2>
Step-by-step explanation:
Put the values of x from the domain to the equation of the function
f(x) = 2x² - 8
for x = -2
f(-2) = 2(-2)² - 8 = 2(4) - 8 = 8 - 8 = 0
for x = 3
f(3) = 2(3)² - 8 = 2(9) - 8 = 18 - 8 = 10
for x = 5
f(5) = 2(5)² - 8 = 2(25) - 8 = 50 - 8 = 42
Answer:
Step-by-step explanation:
plug the numbers in and see if it is true
x=3, y=8
y=7x+8
8=7(3)+8
8=29
is not true, so it is not a solution. even if it might be a solution for the other equation, it is not true for this equation so it is not a solution for this system
how to find an equation: since y=7x+8 and y=x+1, then
7x+8=y, and y=x+1
7x+8=y=y=x+1
7x+8=x+1
6x+8=1
6x=-7
x=-7/6
y=x+1
y=-1/6
solution: (-1 1/6, -1/6)
If x is the number of berries you can buy with 1 dollar,
1 pound of blueberries = $4.00
x pound of berries = $1.00
Lets set up a proportion- because these are directly proportional- when there is more pounds of berries, it will cost more.
Cross multiply
4x=1
Divide both sides by 4 to isolate x
x=1/4 or $0.25
6 apples = $2.70
so,
1 apple = 2.70/6 which is $.45
t = 0.45a
