A graph has average temperature (degrees Fahrenheit) on the x-axis, from 0 to 60, and total coat sales on the y-axis, from 0 to

100. A trend line goes through points (55, 50) and (65, 40). Quincy claims that if 80 coats are sold, the outside temperature is likely to be about 42°F. Did Quincy make a reliable prediction? If not, what was his mistake? Yes. Quincy’s prediction is reliable. No. Quincy should have used the trend line to find the corresponding y value when x=80. No. Quincy should have used the trend line to find the corresponding x value when y=80. No. The prediction is extrapolated, so it is too far off the graph to be reliable.

Height is 2ft. More than its width. If the total area is 99ft squared , determine the dimensions of the painting.
lesantik [10]

Answer: 9\times 11\ ft^2

Step-by-step explanation:

Given

Height is 2\ ft more than its width

Suppose the width is x. So, height becomes x+2

Area of the painting is 99\ ft^2

Area is the product of width and height

\therefore 99=x(x+2)\\\Rightarrow 99=x^2+2x\\\Rightarrow x^2+2x-99=0\\\Rightarrow x^2+11x-9x-99=0\\\Rightarrow (x+11)(x-9)=0\\\Rightarrow x=-11,9

Neglect the negative values

\text{Width =}9\ ft\\\text{height =}9+2=11\ ft

PLEASE HELP! <br><br> i’ll mark brainliest if you’re correct!
Jobisdone [24]

Answer:

y = 5

Step-by-step explanation:

Since this is an isosceles triangle, Angle B and Angle C are equivalent. We can use this to find x

3x = 75

x = 25

Angles in a triangle add up to 180, so knowing the measure of Angle B and Angle C, we can find the measure of Angle A

Angle A = 180-(75+75)

Angle A = 180-150

Angle A = 30

We know Angle A = 4y+10

4y + 10 = 30

4y = 20

y = 5
