help me i need it so bad

Answer:

x=12

Step-by-step explanation:

(2x-4)/5=4

We move all terms to the left:

(2x-4)/5-(4)=0

We multiply all the terms by the denominator

(2x-4)-4*5=0

We add all the numbers together, and all the variables

(2x-4)-20=0

We get rid of parentheses

2x-4-20=0

We add all the numbers together, and all the variables

2x-24=0

We move all terms containing x to the left, all other terms to the right

2x=24

x=24/2

x=12

Answer:

x = 12

Step-by-step explanation:

Given

[tex]\frac{2x-4}{5}[/tex] = 4 ( multiply both sides by 5 to clear the fraction )

2x - 4 = 20 ( add 4 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Question 18: 453,600

Step-by-step explanation:

Answer:

y=x-3

Step-by-step explanation:

The slope is just x, and the y intercept will be one over from (1,-2) which is (0,-3), so -3 is the starting point.

Answer:

the answer is b

Step-by-step explanation:

the answer would be b because you add 12+12 then 5+5 and if you add those together it would be 34 then you would add the diagonal lines together which would be 20 so then you would add 34 plus 26 and then you would get 60 which is b

Answer:

bc = 2

Step-by-step explanation:

From [tex]a/b = 8[/tex]

[tex]a=8b[/tex] (times b on both sides)

We can then substitute [tex]a[/tex] for [tex]8b[/tex]:

[tex]ac-5=11[/tex] (given equation)

[tex]8bc-5=11[/tex]

[tex]8bc=16[/tex]

[tex]bc=2[/tex]

I hope this helps :)

Answer:

Dimensions: 11 meters by 27 meters

2. [tex]76=2w+2(2w+5)[/tex]

Step-by-step explanation:

Finding Dimensions:

The perimeter of a rectangle can be written as [tex]2l+2w[/tex] where [tex]l[/tex] is the length and [tex]w[/tex] is the width. It is given that the length is 5 more than twice the length of width and the perimeter of the rectangle is 76 meters.

With this information we can write:

Length = [tex]2w+5[/tex]

[tex]2(2w+5)+2w = 76[/tex] (perimeter of the rectangle)

[tex]4w+10+2w=76[/tex]

[tex]6w=66[/tex]

[tex]w=11[/tex]

Length = [tex]2(11)+5[/tex]

Length = [tex]27[/tex]

∴ The dimensions of the rectangle is 11 meters by 27 meters.

Perimeter

Since the length can be written as [tex]2w+5[/tex], the equation that represents the perimeter of the rectangle is [tex]76=2w+2(2w+5)[/tex]

Answer:

Step-by-step explanation:

a. Yes is proportional with the cost because they depend on one another

b. (0,0) means if we buy 0 cookies we pay $0

c. (1, 0.50) means that if we buy 1 cookie we have to pay $0.50

d. the unit rate is how much we pay for one cookie so is $0.50 per 1 cookie

Answer:

Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal. Comment on David Severin's post “Congruent means same shape and same size.

Step-by-step explanation:

Answer:  C . The slope is -4/3  and the y-intercept is 4.

Step-by-step explanation:

Using the two given points, we will use them to evaluate the slope and the y intercept.  

(-1.5,6)

( 4.5,-2)  

To find the slope we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the point.

6-(-2) = 8  

-1.5 - 4.5 = -6

Slope :  8/-6=  -4/3.

Since the slope is -4/3, we will use the formula  y= mx + b to find the y intercept. In the formula  y= mx + b, the slope is m and b is the y intercept.  

Use one of the given points, and input its x and y values into the formula including the slope to solve for b(the y-intercept).

We will use the point,  ( -1.5,6)  

6 = -4/3(-1.5) + b

6 = 2 + b  

-2   -2

b = 4.

b is indeed equal to 4 because it even indicates on the  graph that the y intercept is 4 which is where x is equal to 0.

Answer:

For the function: [tex]g(x)=-x^2-3x+5[/tex], the average rate of change of function over the interval [tex]-7\leq x\leq 2[/tex] is 2

Step-by-step explanation:

We are given function: [tex]g(x)=-x^2-3x+5[/tex], we need to find average rate of change of function over the interval [tex]-7\leq x\leq 2[/tex]

The formula used is: [tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}[/tex]

We have b=2 and a= -7

Finding f(b) and f(a)

Finding g(b) by putting x=2

[tex]g(x)=-x^2-3x+5\\g(2)=-(2)^2-3(2)+5\\g(2)=-4-6+5\\g(2)=-10+5\\g(2)=-5[/tex]

Finding g(a) by putting x=-7

[tex]g(x)=-x^2-3x+5\\g(-7)=-(-7)^2-3(-7)+5\\g(-7)=-49+21+5\\g(-7)=-23[/tex]

Now, finding average rate of change when g(b)=-5 and g(a)=-23

[tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}\\Average \ rate \ of \ change=\frac{-5-(-23)}{2-(-7)}\\Average \ rate \ of \ change=\frac{-5+23}{2+7}\\Average \ rate \ of \ change=\frac{18}{9}\\Average \ rate \ of \ change=2[/tex]

So, Average rate of change = 2

Therefore for the function: [tex]g(x)=-x^2-3x+5[/tex], the average rate of change of function over the interval [tex]-7\leq x\leq 2[/tex] is 2

Answer:

8x -16y = 24

Step-by-step explanation:

8x - 16y= -14

A parallel line (i.e. same slope) will be: 8x - 16y= c

We have to find the value of "c".

If it passes through (x, y) = (3, 0) ⇒ 24 - 0 =  c,

so equation is 8x -16y = 24

Answer:

HB = 13

Step-by-step explanation:

In triangle GHJ, points A, B, C are mid points of the sides GH, HJ, GJ respectively.

Therefore by Mid-segment Theorem.

[tex]AC = \frac{1}{2} HJ \\ \\ 3y - 5 = \frac{1}{2} (4y + 2) \\ \\ 3y - 5 = \frac{1}{2} \times 2 (2y + 1) \\ \\ 3y - 5 = 2y + 1\\ \\ 3y - 2y = 5 + 1 \\ \\ y = 6 \\ \\ HJ = 4y + 2 \\ \\ HJ = 4 \times 6 + 2 \\ \\ HJ = 24 + 2 \\ \\ HJ = 26 \\ \\ HB= \frac{1}{2} HJ \\ \\ HB= \frac{1}{2} \times 26 \\ \\ \huge \red{ \boxed{ HB= 13}}[/tex]
