Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7
<span>The plumber's hourly rate is $43. To come to this answer, I first subtracted the $45 fee from 303. That answer was 258, which I divided by 6, because that was the number of hours the plumber worked. That answer was 43, so his hourly rate is $43.</span>
Answer:
y = 4x + 24
Step-by-step explanation:
The slope is the number in front of the x-value.
Slope intercept form is in the form of
y = mx + b (or as how I learned it)
m is the slope, and b is the y-intercept (the number that is left on the side.)
You can rearrange this by moving the x to the right side by subtracting it from both sides.
You now have 1/8y = 3 - 1/2x
which can be rearranged to
1/8y = -1/2x + 3.
You need to change the y to 1 whole instead of 1/8, so you multiply it by 8 since 8 divided by 8 is 1.
y = -4x + 24
