Answer:

x = - 7

Step-by-step explanation:

Express the diagrams in equation form with output y

A y = 5x - 4

B y = 3x + 8

Equate the right sides so that A is 3 times B

5x - 4 = 3(3x + 8) ← distribute parenthesis

5x - 4 = 9x + 24 ( subtract 9x from both sides )

- 4x - 4 = 24 ( add 4 to both sides )

- 4x = 28 ( divide both sides by - 4 )

x = - 7

As a check

A  y = 5(- 7) - 4 = - 35 - 4 = - 39

B  y = 3(- 7) + 8 = - 21 + 8 = - 13

then - 13 × 3 = - 39

The required input is x = - 7

Two circles have radii of 4 units and 6 units. What is the radius of a circle whose area is equal to the sum of the areas of the
Bumek [7]

Answer:

Step-by-step explanation:

We that the area of a circle is Pi times r^2 where r is the radius

Let A be the area of the first circle and S the area of the second one and T the total one

A=4^2× Pi

S=6^2× Pi

T = Pi( 4^2 +6^2)

= Pi ( 16+36) = Pi× 52

52 is the radius square

So r = root square 52 = 2 root square 13

What is the correct answer please
Verizon [17]

Answer:

C

Step-by-step explanation:

\frac{15y-10}{3x} = 6 ( multiply both sides by 3x to clear the fraction )

15y - 10 = 18x ( add 10 to both sides )

15y = 18x + 10 ( divide terms by 15 )

y = \frac{18}{15} x + \frac{10}{15} , that is

y = \frac{6}{5} x + \frac{2}{3} → C
