Answer:
see explanation
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = P(- 2, 2) and (x₂, y₂ ) = Q(2, 2)
m = = = 0 ← slope of line PQ
This indicates the line PQ is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 2, 2) and (2, 2) with y- coordinates of 2
Thus y = 2 ← equation of line PQ
7) A. 1.8
divide 9 by 5
8) B. 0.444...
divide 4 by 9
9) You're correct: It's D. 3/5
Divide 1 1/5 by 2
The ratio of blue paint to yellow paint is 2 : 3.
The total number of blue paint he used on the first and second day is 10.
The number of yellow paint he used on the first and second day is 15.
On the third day, the highest number of can of blue paint he can use is 2
On the third day, the highest number of can of yellow paint he can use is 3.
<h3>What is the highest number of blue and yellow paint he can use?</h3>
The ratio of blue paint to yellow paint can be determined by determining the simplest form of the paints used: 4 : 6 = 2: 3
Total blue paint cans used on the first and second day = 4 + 6 = 10
Blue paint cans remaining = 14 - 10 = 4
Total yellow paint cans used on the first and second day = 6 + 9 = 15 cans
Yellow paint cans remaining = 20 - 15 = 5 cans
