I got -1/2 the whole formula would be y=-1/2x+0
f(-3) = -7(-3) - 7
= 21 - 7 = 14
f(0) = -7(0) -7
= 0 -7 = (-7)
f(5) = -7(5)-7
= (-35) - 7 = (-42)
f(x-2) = -7(x-2) -7
= (-7x) + 14 - 7
7x = 7
x = 1

Step-by-step explanation:
They are exterior angles so they have to be the same.
Answer:
He had 78$ at the end of the day
Step-by-step explanation:
Adding up all the expenses he made then adding them to 51.50,

Answer:
Reject H0
Step-by-step explanation:
Given :
H0: The frequencies are equal. H1: The frequencies are not equal
Category f0 A 10 B 30 C 30 D 10
Total f0 = (10 + 30 + 30 + 10) = 80
Expected frequency is the same for all categories :
Expected frequency = 1/4 * 80 = 20
χ² = Σ(observed - Expected)² / Expected
χ² = (10-20)^2 / 20 + (30-20)^2 /20 + (30-20)^2 / 20 + (10-20)^2 / 20
χ² = (5 + 5 + 5 + 5) = 20
Pvalue = 0.00017
Pvalue < α
