Answer:
the temperature rose by 34*F
Step-by-step explanation:
-13*F + 34 = 21*F
Given,
2x - 1/2 = 3 - x
2x + x = 3 + 1/2
3x = 7/2
3x = 3.5
x = 3.5/3
x = 1.167
Answer:
y = 3x - 5
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
Substitute the values for the variables.
y - 7 = 3(x - 4)
y - 7 = 3x - 12
y = 3x - 5
When we have a function such as h(x) = 2x, and we want to find the value of h at a given x value, we plug in the given number for x. For example, h(3) = 2*3 = 6.
We do the same thing with g(f(7)). In this case we plug 7 into f(x) for x, then plug the result of f(7) into g(x) for x.
f(7) = 15*7 - 12 = 93
g(93) = -15*93^2 + 14*93 - 10 = -128443
okay so the answer is a. and b. since how you put them they are the same. so the answer is -4 x 8
hope this helps
