-4(3x+1)+x-3=15

start using the method PEMDAS

(parenthesis, exponents, multiplication, division, addition, subtraction)

so,

start with multiplying since its the third option to start with

-12x-4+x-3=15

now add like variables

-11x-7=15\\

continue by changing the signs to the other side +7 on both sides

-11x=22

now divide 11 on both sides

\frac{22}{-11} equals to negative 2

Answer : -2

Hope this helps~

x =  - 2is the answer

Explanation -

-4(3x+1)+x-3=15

=  >  - 12x - 4 + x - 3 = 15

=  >  - 11x - 7 = 15

=  >  - 11x = 15 + 7

- 11x = 22=  > x =  -  \frac{22}{11}

=  > x =  - 2

The quadrilaterals JKLM and PQRS are similar.
Sveta_85 [38]

Answer:

x = 2.8

Step-by-step explanation:

If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:

KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7

JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7

LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7

This shows that the ratio of KJ : QP = 5/7

KJ : QP = 2 : x = 2 / x

Therefore, \frac{2}{x}=\frac{5}{7}

cross multiply:  14 = 5x

Divide both sides by 5:  x = 2.8

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)
Wittaler [7]

Answer:

  • y = -2/3x + 8/3a

Step-by-step explanation:

<u>Given points</u>

  • (a, 2a) and (-5a, 6a)

<u>Slope-intercept form</u>

  • y = mx + b

<u>Slope of the line is</u>

  • m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3

<u>The y-intercept is:</u>

  • 2a = -2/3*a + b
  • b = 2a + 2/3a
  • b= 8/3a

<u>So the line is:</u>

  • y = -2/3x + 8/3a

Yes. 
a test for a function is the vertical line test, so think about drawing a vertical line on top of this picture. if at any point the line is touching the graph more than once, it is not a function. this graph passes the vertical line test
