Answer:
y = -4x - 7
Step-by-step explanation:
we use the slope intercept formula given by; y = mx + b
b = y intercept, which is when x = 0
m = slope
so they tell us the slope.. we just need to find b - the y intercept.
y = mx + b
plug in your coordinates (-2,1)
1 = -4(-2) + b
1 = 8 + b
1 - 8 = b
-7 = b
put it all together.
y = -4x - 7
Answer:
60
Step-by-step explanation:
180=(x+30)+(4x)
Ok, combine like terms. That'll give you
180=5x+30.
Now solve for x. X is going to equal 30.
Then substitute 30 for x in the angles. One angle will be 60 and the other will be 120.
60 is smaller than 120 so that's your answer.
Answer:
B. y = 0.097x + 11.142
Step-by-step explanation:
In order to find the best equation to descibe the housing price, we have to calculate the slope of the line first.
The equation of the line can be written as

where m is the slope and q the y-intercept.
In order to have the most accurate estimate for the slope, we use the first point and the last point, that are:
(1900, 196)
and
(2200, 225)
The slope of the line is calculated as:

So, the slope of the line is 0.097.
Therefore, the correct option is the only one having a slope of 0.097, which is:
B. y = 0.097x + 11.142
Answer:
D is the correct answer
if you want explanation you can comment down
Circumference (C) = 2 π·r ; where r is the radius = diameter(d)/2
C = 2 π·(14/2)
=2 π·(7)
= 14π
