Answer:

y = 5x - 7

Step-by-step explanation:

y = mx + c

y = 5x + c

to find c, input given coordinates

8 = 5 x 3 + c

8 = 15 + c

-c = 15 - 8

-c = 7

c = -7

put that all together and you get:

y = 5x - 7

A certain television is advertised as a 53-inch TV (the diagonal length). If the width of
zhenek [66]

The TV is 45 inches tall.

Step-by-step explanation:

The diagonal length of television = 53 inches

Width of TV = 28 inches

As TV is in rectangular or square shape, a diagonal will form a right triangle

Where,

Diagonal = hypotenuse = c = 53 inches

Width = base = b = 28 inches

Length = perpendicular = a

we will use pythagorean theorem to find the length.

a^2+b^2=c^2\\a^2+(28)^2=(53)^2\\a^2+784=2809\\a^2=2809-784\\a^2=2025

Taking square root on both sides

\sqrt{a^2}=\sqrt{2025}\\a=45

The TV is 45 inches tall.

Triangles WSR and TVR are similar. Find x.
Vlad [161]

They are similar. Set the proportions equal to each other

(x + 8)/8 = (x+14)/12

Cross multiply

(x + 8)/8 (8)(12) = (x + 14)/12 (12)(8)

12(x + 8) = 8(x + 14)

Distribute the 12 and 8 to the corresponding monomials inside the parenthesis

12(x + 8) = 12x + 96

8(x + 14) = 8x + 112

12x + 96 = 8x + 112

Isolate the x. Subtract 8x from both sides and 96 from both sides

12x (-8x) + 96 (-96) = 8x (-8x) + 112 (-96)

12x - 8x = 112 - 96

4x = 16

Isolate the equal sign. Divide 4 from both sides

4x/4 = 16/4

x = 16/4

x = 4

------------------------------------------------------------------------------------------------------------------

4 is your answer for x
