Answer:

f(x) = 7.5x

Step-by-step explanation:

you can find the slope by using the slope formula (y2-y1)/(x2-x1). you can use any of the values but for this example I'll be using (2, 15) and (4, 30).

(30-15)/(4-2) = 15/2 = 7.5.

now we can use one of the coordinates to find the y-intercept by plugging the known values in the equation y=mx+b where m is the slope and b is the y-intercept.

for this example I'll be using (2, 15) but you could use any of the values you gave.

15 = 7.5(2) + b

15 = 15 + b

0 = b

so now we have the function rule

f(x) = 7.5x + 0 or just f(x) = 7.5x

Area = length x width
22 = length x 2
length = 22 ÷ 2 = 11 inches

Length is 3 less than an unknown number
So the unknown number is length + 3 = 11 + 3 = 15 inches

Find the reflex angle 150 degrees ?

34kurt

A reflex angle is equal to the sum of 180 degreesand any of the primaryangles (acute, right andobtuse angles). Therefore, Reflex angle = 180° + Acute angle.

First, make sure that it is the reflex angle you’re being asked to measure! Lots of children mistakenly, but very carefully measure the wrong angle. Usually, the angle you’re being asked to measure will have a little circle drawn around the point to show you which side needs measuring

2. Make a small mark on your paper to show where 180° is. If you want to, you could even draw a faint line to show the 180° line.

3.You now need to measure the remainder. Using the outside scale on your protractor, measure the angle from the 180° line you have drawn to the second line you have been given (in this case y to x).

4. Add together 180° to the second measurement and this will be your reflex angle.

5. If you want to check your answer, measure the inside angle and check that the two measurements added together equal 360°.
