Answer:

y=-2x+21

Step-by-step explanation:

use y2-y1/x2-x1 to find the slope so= -17-3/19-9=-20/10=-2

so once you find the slope take one of the points and plug it into the slope-int equation so... if you take (9,3) and take your slope (-2) so it would be: 3=-2(9)+b solve for b to get 21=b as your int. so.. y=-2x+21

Find the difference ( 9/4x+6) − (− 5/4x−24)=

Amiraneli [1.4K]

Answer:

$=\frac{7}{2}x+30$

Step-by-step explanation:

So we have the equation:

$(\frac{9}{4}x+6)-(-\frac{5}{4}x-24})$

First, distribute the negative on the right:

$=(\frac{9}{4}x+6)+(\frac{5}{4}x+24})$

Combine like terms:

$=(\frac{9}{4}x+\frac{5}{4}x})+(6+24)$

Add:

$=\frac{14}{4}x+30$

We can reduce our fraction by dividing both layers by 2. Thus:

$=\frac{7}{2}x+30$

So this would be our answer :)

The perimeter of the rectangle below is 132 units. Find the length of side AB.

melisa1 [442]

Answer:

AB = 35

Step-by-step explanation:

For the value of variable z....;

;Perimetre = 132

; 132 = 2(4z + 3) + 2(5z)

; 132 = 8z + 6 + 10z

; 132 - 6 = 8z + 10z

; 126 = 18z

;the value of...z = 7

Therefore the value of length AB;

AB = 5z...then substitute the value of z into the length of AB

; AB = 5(7)

;AB = 35

Hey there!

ANSWER: $\frac{23}{20}$

EXPLANATION:

To find the answer to your question, you will need to add.

$\frac{3}{4}+\frac{2}{5}$

First, multiply the denominator.

$5*4=20$

So the denominator will be 20.

Now move on to the numerator. Multiply 5 by 3.

$5*3=15$

Now multiply 4 bu 2.

$4*2=8$

If you want to get the numerator, add what you got after multiply.

$15+8=23$

The numerator is 23. So now let's complete the fraction.

$\frac{23}{20}$

This is your answer!

Hope this helps!
