Answer:

y = 6

Step-by-step explanation:

5y + 5 = 35

5y = 35 - 5

5y = 30

y = 30 / 5

y = 6

Hope that helps!

Honestly dunno what 2 do

alexdok [17]

Step-by-step explanation:

For number one, you are looking for how many multiplication equations can equal the number given. For example,

C) 12: 1, 12, 6, 2, 3, 4,

For number 2, composite numbers are numbers that are products of two smaller numbers.

For example, 30=15x2, so it is composite. Try dividing the numbers to see if they are composite.

For number 3,

a) two factors: 5 (1, 5)

b) four factors: 15 (1, 15, 3, 5)

c) five factors: 20 (1, 2, 4, 5, 20)

Equation
--------------------------------------------------------------------------
$y - 9 = - \dfrac{1}{2} (x + 2)$

--------------------------------------------------------------------------
Rearrange the equation
--------------------------------------------------------------------------
$y - 9 = - \dfrac{1}{2} (x + 2) \\ \\
 y - 9 = - \dfrac{1}{2}x - 1 \\ \\
 y - 9 + 9 = - \dfrac{1}{2}x - 1 + 9 \ \Longleftarrow \text{add 9 to both side} \\ \\
 y = -\dfrac{1}{2}x + 8$

slope of the perpendicular line
--------------------------------------------------------------------------
slope = 2

(*the slope of the perpendicular line is the negative reciprocal of the slope of line)

---------------------------------------------------------------------------
Substitute slope into equation y = mx + c
---------------------------------------------------------------------------
y = 2x + c

---------------------------------------------------------------------------
Find y-intercept
---------------------------------------------------------------------------
y = 2x + c
At point (0, 4)
4 = 2(0) + c
c = 4

----------------------------------------------------------------------------
Substitute y-intercept into the equation y = 2x + c
-----------------------------------------------------------------------------
y = 2x + 4

----------------------------------------------------------------------------
Answer: y = 2x + 4
-----------------------------------------------------------------------------

Expand and simplify (x + 5)(x-9)

aev [14]

Answer:is

=x(x-4)-45

Step-by-step explanation:q= (x+5) (x-9)

in the mathematical rules when the variables are in the brackets it means we have to remove the brackets by,multiplying the first variable to the second variable in another bracket, and then so on.

=x^2-9x+5x-45

=x^2-4x-45

by simplifying completely it will become,

=x(x-4) -45

that's the answer.

Find the slope of the line passing through the two points.

pogonyaev

Formula for slope: y2-y1/x2-x1
Plug in values.

The price of an item in a shopping cart is c dollars. If the sales tax on the item is 9%, and the expression c + 0.09c represent

Crank

If you factor c + 0.09c, we get c(1 + 0.09), which is the same as (1 + 0.09)c.

If we add the numbers inside the parentheses (1 + 0.09)c we get 1.09c.

The answer is choice B and E.
