Answer:

x=3/4y-6

Step-by-step explanation:

Solve for x

-4x+3y=24

Add -3y to both sides.

-4x+3y+-3y=24+-3y

-4x=-3y=+24

Then Divide both sides by -4

-4x/-4= -3y+24/-4

x=3/4y-6

Answer:

The value of x:

\boxed {x = \frac{3y}{4} - 6}

The value of y:

\boxed {y = \frac{4x}{3} + 8}

Step-by-step explanation:

Solve for the value of x:

-4x + 3y = 24

-Subtract 3y to both sides:

-4x + 3y - 3y = 24 - 3y

-4x = 24 - 3y

-Divide both sides by -4:

\frac{-4x}{-4} = \frac{24 - 3y}{-4}

\boxed {x = \frac{3y}{4} - 6}

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

Solve for the value of y:

-4x + 3y = 24

-Add 4x to both sides:

-4x + 4x + 3y = 24 + 4x

3y = 24 + 4x

-Remember that the equation is in <u>Standard Form</u>:

3y = 4x + 24

-Divide both sides by 3:

\frac{3y}{3} = \frac{4x + 24}{3}

\boxed {y = \frac{4x}{3} + 8}

Answer: B

Step-by-step explanation: Formula of a slope on a table is Δy/Δx, in this case it is 15/5 simplified is 5/1. So the slope is 5/1. The y-intercept is the first number which is -75. So the answer is y=5x-75 which is b, your welcome

Solve the system of linear equations by substitution.<br><br>−2x−5y=3<br> 3x+8y=−6
Sliva [168]
First you want to know what y or x is i chose y for this on 

so the equation i'm going to use is -2x-5y=3
i want to solve for y

-2x-5y=3
+2x        +2x

-5y=2x+3
 /-5   /-5  /-5
y=-2/5x+-3/5

Now that i solved for y we substitute our answer into the next equation to solve for x like this:

3x+8y=-6
3x+8(-2/5x+-3/5)=-6
3x+ -3.2x+-4.8=-6
-0.2x+-4.8=-6
          +4.8  +4.8
-0.2x=-1.2
/-0.2    /-0.2
x=6

After you know what x is you substitute it in for any of the equations that we started with. I picked 3x+8y=-6 to find y.

3x+8y=-6
3*6+8y=-6
18+8y=-6
-18      -18
8y=-24
/8     /8
y=-3

Since we know what x and y are we substitute it with any of the equations that we started with. i picked -2x-5y=3

-2*6-5*-3=3
-12- -15=3
3=3 
so our solution (6,-3) works

Please help me please pleaee

Hello,

A.i. the circumference of a circle is nothing else but its perimeter which formula is π × diameter = π × 2 × radius

Let π = 22/7 ≈ 3.142857, the egyptian approximation

Then if C is the circumference of the circle i., C = 22/7 × 21 = (22 × 21) / 7 = (22× 7×3 )/7 = 22 ×3 = 66 cm

ii. Applying the same formula for the second circle gives us C = 22/7 × 8 = 176/7 ≈ 25.14 meters, rounded to the nearest hundredth...

Good luck !
