<span>if at 7 it was 65 and at 9 it was 55, that means temperature is decreasing by 5 per hour</span>
Leah has 5 meters of cloth in total, because she has a total of 5 friends which means when divided equally, she has given each friend 1 meter of cloth.
Answer:
Step-by-step explanation:
The average speed of the flights mph was 700 because if you divide 2100/3 you get 700
Answer:
с. 60
Step-by-step explanation:
This is an equilateral triangle since all the sides are the same.
That means all the angles are the same.
The sum of the angles is 180
There are 3 angles
180/3 = 60
Each angle is 60 degrees
Answer:y = - 2x + 17
Step-by-step explanation:
The equation of a line, represented in the slope-intercept form, is
y = mx + c
Where
Slope = m
c = intercept
Looking at the equation given,
y=1/2x + 8
Slope,m = 1/2
If a line is perpendicular to a another line, then the slope of one line is equal to the negative reciprocal of the other line. It means that the slope of the perpendicular line that passes through that passes through ( 4, 9 ) will be -2
To determine c,
We will substitute m = -2, y = 9 and x = 4 into the slope intercept equation,
y = mx + c. It becomes
9 = -2 × 4 + c
9 = -8 + c
c = 9 + 8 = 17
The equation becomes
y = - 2x + 17
