Y = kx
k = y/x = 63/14 = 4.5
so
y = 4.5(28) = 126
answer
<span>y = 126 when x = 28.</span>
What is the slope of the line through (2,−2)(2,-2)(2,−2)left parenthesis, 2, comma, minus, 2, right parenthesis and (9,3)(9,3)(9
Musya8 [376]
The slope of line passing through (2,-2) and (9,3) is 5/7
Step-by-step explanation:
Given two points are:
(x1,y1) = (2,-2)
(x2,y2) = (9,3)
The slope is defined as the steepness of a line.
When two points are known, through which the line passes,
The slope is given by:
Putting the values
Hence,
The slope of line passing through (2,-2) and (9,3) is 5/7

Answer:
17.11%
Step-by-step explanation:
since 43.2 months is the mean, and the standard deviation is 7.7 months
that means if we take the z score:
z=(36-43.2)/7.7
now that we know how many standard deviations you are away from the mean: -0.9351
using the zscore table you can find the proportion, or you can use the calculator if you have one that can do that.
you get 0.1711 which in percentages is 17.11%
Answer:
x = 3, x = 4
Step-by-step explanation:
Given
x³ - 2x² - 11x + 12 = x³ - 13x - 12
Subtract x³ - 13x - 12 from both sides
- 2x² + 2x + 24 = 0 ← in standard form ( divide all terms by - 2 )
x² - x - 12 = 0
(x - 4)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 3 = 0 ⇒ x = 3
