Step-by-step explanation:

Simplify the left side:

5x - 20 = 3x + 4

Move all terms containing x to the left side of the equation:

2x - 20 = 4

Move all terms not containing x to the right side of the equation:

2x = 24

Divide each term by 2 and simplify:

x = 12

Answer:

$\boxed{\bold{x=12}}$

Step-by-step explanation:

Add 20 to both sides

$\bold{5x-20+20=3x+4+20}$

Simplify

$\bold{5x=3x+24}$

Subtract 3x from both sides

$\bold{5x-3x=3x+24-3x}$

Simplify

$\bold{2x=24}$

Divide both sides by 2

$\bold{\frac{2x}{2}=\frac{24}{2}}$

Simplify

$\bold{x=12}$

What are the X and Y intercepts of y= -2(x-4)2 +3

kari74 [83]

Answer: x-intercepts are ( 2.775,0) and (5.225,0)

And y-intercept is (0,-29)

Step-by-step explanation:

Here the given equation is,

$y = -2(x-4)^2+3$

For x-intercept, y = 0,

Put y = 0 in the above equation of parabola,

We get, $-2(x-4)^2 + 3 = 0$

$-2(x^2+16+8x) + 3 = 0$

$-2x^2-32-16x + 3 = 0$

$-2x^2-16x -29 = 0$

By solving this equation,

We get, x = 2.775 or x = 5.225

Therefore, x-intercept of the given parabola are (2.775, 0) and (5.225,0)

Now, for y-intercept, x = 0

By putting x = 0 in the given equation of parabola,

We get, y = -29

Thus, y-intercept of the given parabola = (0,-29)

If one raw contains 3x-2 trees & if the total trees in the rectangle are 24x-16, that means Horizontal Rows x Vertical Rows =Total number of trees:

(3x-2) * Vertical Rows = 24x-16 ===> Vertical Rows =(24x-16) / (3x-2)

Perform the division & you will find Vertical Rows =8

Mr brown shares with the class that 70%of the students got a A on the English vocabulary quiz if mr brown has 100 students creat

Harrizon [31]

70% of 100 is 70 students. Unfortunately I can not make a model for you but here's an idea: Draw a large circle. Next, draw a line halfway down the circle, and halfwar down draw another line to the right, this making it look like three fourths. Then, color the larger space in one color and the other smaller space that looks like a small slice of pie in another color. On the larger piece write "70% who got an A" and on the smaller write "30% who didn't get an A" At the bottom you can write 70 students out of 100 got an A on the test.
