Answer:

y=-\frac{2}{3}x+\frac{19}{3}

Step-by-step explanation:

Lines that are perpendicular to each other have opposite reciprocal slopes. So, in this case, the slope that is perpendicular to 3/2 would be -2/3. In order for the line with that slope to pass (-4,9), we would need to plug in the coordinate point and solve for the y-intercept:

y=mx+b

y=-\frac{2}{3}x+b

9=-\frac{2}{3}(-4)+b

9=\frac{8}{3}+b

\frac{19}{3}=b

Therefore, the equation in slope-intercept form would be y=-\frac{2}{3}x+\frac{19}{3}

PLEASE HELP WILL MARK BRAINLIEST
LekaFEV [45]

Step-by-step explanation:

In trapezoid ABCD, it is given that:

AE = BE & DF = CF

Hence, points E and F are the mid points of the sides AB and CD respectively.

We know that:

In a trapezoid length of the line segment joining the mid points of non parallel sides is equal to one half of the sum of lengths of the parallel sides.

\therefore \: 4x =  \frac{1}{2}  \{(x + 5) + 44 \} \\  \\  \therefore \: 4x =  \frac{1}{2}  \{x + 5 + 44 \} \\  \\ \therefore \: 4x  \times 2=  \{x + 49\} \\  \\ \therefore \: 8x =  x + 49 \\  \\  \therefore \: 8x  -  x  =  49 \\  \\  \therefore \: 8x  -  x  =  49 \\  \\ \therefore \:7x = 49 \\  \\ \therefore \:x =  \frac{49}{7}  \\  \\  \therefore \:x =  7\\  \\ \therefore \:4x = 4\times 7.. (\because EF = 4x)\\  \\   \:  \:  \:  \:  \: \huge \red{ \boxed{\therefore \:EF =  28}}

Write down all of the #'s on a piece of paper
18,23,15,16,15,17,22,16,19,11,24,14,12,16,20,18,14,13,21,11

Put them in order
11,11,12,13,1414,15,15,16,16,16,17,18,18,19,20,21,22
Cross em off on eah side until you reach the middle 
16, 16
Since there's 2 instead of 1 middle # Add up the 2 (16+16 = 32) 
Then divide by 2 (32/2 = 16)

You're answer is 16

How many solutions exists for the given equation?<br> 3x+13=3(x+6)+1
kolbaska11 [484]

Answer:

No Solutions.

Step-by-step explanation:

original equation

3x+13 = 3(x+6)+1

distribute 3

3x+13 = 3x+18+1

simplify

3x+13 = 3x+19

since the slope is the same for both equations and the y-intercept is different the two equations are parallel meaning they will never intersect so there are no solutions.
