The answer would by -9 since you subtracted 9 from 5 which decreased the value of y.

"the answer would be -9 since you subtracted 9 from 5 which decreased the value of y."

how is it negative 9 if you were to subtract 9 - 5 it would be 4
and if you were to subtract 5 - 9 it would be negative 4

Simplify foundation of alegebra
Eva8 [605]

1.) -8 + 10(6 + 4r)

First multiply the 10 into (6 + 4r)

-8 + 60 + 40r

52 + 40r


2.) (8m² - 8m + 8) - (2m - 7m² - 6)

Distribute the - into (2m - 7m² - 6)

8m² - 8m + 8 - 2m + 7m² + 6

Combine like terms

15m² - 10m + 14

(idk if you need to factor this or if you can leave it as is)

The median is the number that is in the middle of all the other numbers in order but that is not the case
however, it is not the mean either
so we can see that 9.25 is between 9 and 9.5 when 23.5 is ignored
the correct answer is B

kirill115 [55]

Given :

  1. 2 - 1/2y = 0

To find :-

  • The gradient form .

Solution :-

<u>The </u><u>gradient</u><u> form</u><u>/</u><u> </u><u>slope</u><u> intercept</u><u> form</u><u> </u>

  • y = mx + c ,

<u>On </u><u>converting</u><u> </u><u>,</u>

  • 2 - 1/2y = 0
  • 1/2y = 2
  • y = 2*2
  • y = 4

Help on both of these pls<br> also sry the lighting is weird
IRISSAK [1]

Answer:

see explanation

Step-by-step explanation:

The 2 angles form a right angle, thus their sum is 90°, hence

4x + 7 + 35 = 90

4x + 42 = 90 ( subtract 42 from both sides )

4x = 48 ( divide both sides by 4 )

x = 12

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

To calculate the slope m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 4) ← 2 points on the line

m = \frac{4-0}{1-0} = \frac{4}{1} = 4
