Answer:
71°
Step-by-step explanation:
The temperature had to be at least 71° when the heater quit to be able to lose 4° and still be at least 67° when the heater is repaired.
Question is...how did someone know that the heater had failed?
The slope and y-intercept of this function is
B. The slope is 5/6, The y-intercept is (0, -3
<h3>How to find the slope and the y-intercept</h3>
Linear function is a function of the form y = mx + c
m = slope
c = intercept
The slope is represented as m, The slope by definition is the ratio change of the output values to the input values
the slope, m calculated using the points (0, -3) and (6, 2)
m = (y₀ - y₁) / (x₀ - x₁)
m = (2 - -3) / (6 - 0)
m = (5) / (6)
m = 5/6
c = y intercept, from the table
c = -3

Answer:
45 degrees.
Step-by-step explanation:
All interior angles in a triangle add up to 180 degrees.
We can form an equation: x+x+65+25=180
2x+90=180
2x=90
x=45.
Answer:
y = 1/7x + 88/7
Step-by-step explanation:
y = mx +b
since it is perpendicular you have to get the negative reciprocal of the slope which is 1/7
y = 1/7x + b then you would plug in your points
12 = 1/7(-4) + b and then solve for b
12 = -4/7 + b
+ 4/7
88/7 = b
y = 1/7x + 88/7
