we can look at the trend line, find the slope.
let's start at the start of the line, (0, 5).
the line goes up 5 units and goes right 1 unit, so that means the slope is 5/1, or 5.
so you know the slope is 5x. now let's see the y-intercept, ask yourself this, where is the start of the line ? we already answered that: (0, 5). so the y-intercept is 5.
the equation should look like y = 5x + 5, so the answer is C

Step-by-step explanation:
if f = c/lambda
then c = f × lambda
Let
x------> hours worked by Sara last week
y------> hours worked by Joan last week
z------> hours worked by Erin last week
we know that
x=28 hours ------> equation 1
y=x-6-----> equation 2
substitute the value of x in equation 2
y=28-6=22 hours
z=y/2------> equation 3
substitute the value of y in the equation 3
z=22/2=11 hours
<u>the answer is</u>
Sara worked 28 hours last week
Joan worked 22 hours last week
Erin worked 11 hours last week
Answer:
Correct answer is: 7. y = 28° and x = 29° 8. y = 7 and x = 5
Step-by-step explanation:
7.
In the parallelogram, adjacent angles are supplementary and the opposite angles are the same.
According to this:
(3 y - 20) + (4 y + 4) = 180 => 7 y - 16 = 180 => 7 y = 180 + 16 => 7 y = 196
y = 196/7 = 28° => y = 28°
4 x + (2 x + 6) = 180 => 6 x + 6 = 180 => 6 x = 180 - 6 => 6 x = 174
x = 174/6 = 29° => x = 29°
8.
At the parallelogram, the diagonal is split into two equal parts.
According to this:
3 y - 3 = 2 y + 4 => 3 y - 2 y = 4 + 3 => y = 7
x - 1 = 2 x - 6 => 2 x - x = 6 - 1 => x = 5
God with you!!!
