write a linear function f with the values f(2)=4 and f(-7)=9

Answers

Answer 1

Answer:
f(x) = -5/9 x + 5 1/9
Step-by-step explanation:
f(2)=4 and f(−7)=9 means the line pass through (2,4) and (- 7,9)
f(x) = mx + b
m = (y-y') / (x-x') = (9 - 4) / (- 7 - 2) = - 5/9
for (2,4) : b = f(x) - mx = y - mx = 4 - (- 5/9) x 2 = 4 + 10/9 = 46/9 = 5 1/9
f(x) = -5/9 x + 5 1/9
check for (-7, 9) f(-7) = (-5/9) * (-7) + 5 1/9 = 35/9 + 46/9 = 81/9 = 9

Answer:

see explanation

Step-by-step explanation:

The opposite angles of an inscribed quadrilateral are supplementary, thus

5x + 20 + 7x - 8 = 180

12x + 12 = 180 ( subtract 12 from both sides )

12x = 168 ( divide both sides by 12 )

x = 14

Thus

∠ RQP = 10x = 10(14) = 140°

∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )

∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°

∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°

Shasta pools is building my pool. I want the pool to be 8ft longer that it is wide and I want it to cover 240 square ft. Which equations would I use to model the area of the pool? *

Answers

Answer:

area = w² + 8w

Step-by-step explanation:

the equation for calculating the area of something is:

area = length x width

length = 8 + width

area = (8 + width) x width

I will use w instead of width

area = w² + 8w

we can solve for w:

240 = w² + 8w

w² + 8w - 240 = 0

(w - 20) x (w + 12) = 0

so we know that the length of the pool is 20 feet and the width is 12 feet

I NEED HELP on THESE QUESTIONS EXCEPT ONE. Only do 2 and 3

Answers

Answer:

201° and 60°

Step-by-step explanation:

(2)

∠ FHG = [tex]\frac{1}{2}[/tex]( arc ES + arc FG ), that is

128° = [tex]\frac{1}{2}[/tex] ( 55 + FG ) ← multiply both sides by 2

256° = 55° + FG ( subtract 55° from both sides )

201° = major arc FG

(3)

The measure of the secant- tangent angle FTS is half the difference of the intercepted arcs, that is

∠ T = [tex]\frac{1}{2}[/tex] ( arc FS - arc US )

     = [tex]\frac{1}{2}[/tex] (170 - 50)°

     = [tex]\frac{1}{2}[/tex] × 120°

     = 60°

If you were to graph this information, the resulting line would represent a linear function. Using this information from the table and the information on your graph, by how much does the altitude of the plane change for each three-minute change in time during the descent.
a.
The altitude of the plane decreases 2 kilometers for each 3 minutes into the descent.
b.
The altitude of the plane decreases 3 kilometers for each 3 minutes into the descent.
c.
For every 3 minutes, the altitude of the plane increases 3 kilometers.

Since multiplication of two algebraic terms can be done by first multiplying their coefficients and then the variables.
