Answer:
G
Step-by-step explanation:
I say G because when you look at the bar, the maximum is 100% and G is 20 in total. Therefore, the maximums are the same types and both can be divided by 10.
2(t + 5) > 4t - 7(t + 3)
2t + 10 > 4t - 7t - 21
2t + 10 > -3t - 21
2t + 3t > -21 - 10
5t > -31
t > -31/5
Answer:
360cm²
Step-by-step explanation:
area of the parallelogram = base x height
base = 40 -10= 30cm
height = height of the triangle
A = 30*12= 360
Answer:
f⁻¹(x) = x/4 + 1/2
Step-by-step explanation:
To find the inverse of a function, switch the x and y variables, then isolate y.
f(x) replaced y, so you can replace it back.
y = 4x - 2
x = 4y - 2 Switched x and y
x + 2 = 4y Added 2 to both sides
y = x/4 + 2/4 Divided both sides by 4
y = x/4 + 1/2 Simplified
f⁻¹(x) = x/4 + 1/2 Use function notation
10/-5 = -2 so 5 - (-2)= 7
