Which of the following describes the correct first step in solving the equation 2x - 7 = 5?

Answer:

3) x = 21.33

4) x = 33

5) x = 11

Step-by-step explanation:

3: (3x + 17) + (x + 40) + (2x - 5) = 180

6x + 52 = 180

6x = 128

x = 21.333...

4: 180 / 3 = 60

3x - 39 = 60

3x = 99

x = 33

5: 90 + (6x + 7) + (2x - 5) = 180

8x + 2 = 90

8x = 88

x = 11

Answer:

x = 10

Step-by-step explanation:

We would use postulates and theorem to figure out 34 = 3x + 4. Once you set 34 equal to 3x + 4, you would solve for x as can be shown below:

34 = 3x + 4

Subtract 4 from both sides.

30 = 3x

Divide both sides by 3.

10 = x

Answer:

10

Step-by-step explanation:

(3x + 4)° = 34°

x = 10

Answer:

The slope is 1/2

Step-by-step explanation:

The rate of y over the rate of x so it would be y/x. You put the equation y2-y1/x2-x1

Which would look like -3-3/-4-8= -6/-12=6/12 and then you simplify it to 1/2

I hope dis helps

Answer:

1. the vertex form of your function is f(x)= (x+-2)^2+-7

The vertex is at (2,-7)

2. So, the vertex form of your function is f(x)= (x+-7/2)^2 -41/4

The vertex is at (7/2, -41/4)

Step-by-step explanation:

The answer is obviously D.

Answer: It would be -8.

Step-by-step explanation: -4 = x so -4 squared is -16 times 1/2 which is -8.

Count from the origin to the center of the parabola. You will notice that there are 4 units.

So, the axis of symmetry is the line x = 4. The equation x = 4 cuts the parabola exactly in half.

Step-by-step explanation:

[tex]4y - 4x = - 32 \\ \\ 4y = 4x - 32 \\ \\ y = \frac{4x}{4} - \frac{32}{4} \\ \\ y = x - 8 \\ \\ equating \: it \: with \\ \\ y = mx + b \\ \\ m = 1 \\ \therefore \: slope \: = 1 [/tex]

Answer:

x=47 degrees

Step-by-step explanation:

X equals 47 degrees because it is congruent to the other angle that is marked. This is because of Alternate Interior Angles.

We know AD and BC are parallel because the shape is a parallelogram, this means that the other line is a transversal. When you have a transversal going through two parallel lines there are certain rules, including Alternate Interior Angles, which are two angles on opposite sides of the transversal but both on the inside of the parallel lines.

Answer:

pink is 3/16 blue is 1/4

Step-by-step explanation:

Answer:

Pink: 3/16 Blue:4/16 = 1/4

Step-by-step explanation:

Just look at the spinner, and find the fractions!

FYI Pink can not be more simplified, Blue can.

Answer:

$21.59

Step-by-step explanation:

Basically how I did it was to multiply 5.08 by 4, because that would be the cost of 16 bags and then I divided 5.08 by 4 to see how much one bag would cost. One bag costs 1.27. After I've got the answer, I added 1.27 to 20.32 and got $21.59.

Answer:

Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]

Step-by-step explanation:

Given, A(-2, -1), B(10, -1), and R(4, 4).

Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]

Distance between A(-2, -1) and B(10, -1) using distance formula:

[tex] \overline{AB} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(10 -(-2))^2 + (-1 -(-1))^2} [/tex]

[tex] \overline{AB} = \sqrt{(12)^2 + (0)^2} [/tex]

[tex] \overline{AB} = \sqrt{(144 + 0)} [/tex]

[tex] \overline{AB} = \sqrt{144} = 12 [/tex]

Distance between B(10, -1) and R(4, 4):

[tex] \overline{BR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 - 10)^2 + (4 -(-1))^2} [/tex]

[tex] \overline{BR} = \sqrt{(-6)^2 + (5)^2} [/tex]

[tex] \overline{BR} = \sqrt{(36 + 25)} [/tex]

[tex] \overline{BR} = \sqrt{61} [/tex]

Distance between A(-2, -1) and R(4, 4):

[tex] \overline{AR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 -(-2))^2 + (4 -(-1))^2} [/tex]

[tex] \overline{AR} = \sqrt{(6)^2 + (5)^2} [/tex]

[tex] \overline{AR} = \sqrt{(36 + 25)} [/tex]

[tex] \overline{AR} = \sqrt{61} [/tex]

Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]

Perimeter of ∆ABR = [tex] 12 + \sqrt{61} + \sqrt{61} [/tex]

Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]

Answer:

No who is ocean?

Answer: 1.6

Step-by-step explanation: just did it

Half the perimeter is equal to the length plus the width.

326 /2 = 163

Length + width = 163

87 + width = 163

Width = 163 - 87

Width = 76 meters

Answer:

y = 2x+ 4

Step-by-step explanation:

The slope of your line given is 2 and it's y-int is 2 that makes the equation y=2x+2.

Since you want a parrallel line you want the smae slope but with a different y intercept. So the answers is y =2x +4.

Answer:

y= -3/5x + 16

Step-by-step explanation:

slope intercept form: y=mx+b

1. Find the slope: rise over run so 13-19/ 5-(-5) = -3/5

M=-3.5

2. Find the y - intercept by using the point slope form: b= 16

So, y= -3/5x + 16

Answer:

Step-by-step explanation:

Step one:

we are told that the expression for profit is

[tex]p = 1.25n - 475[/tex]-----------------1

the above equation represents the situation

given

profit is  $950

Required

n=number of bars

950=1.25n-475

collect like terms

950-475=1.25n

475=1.25n

divide both sides by 1.25

n=475/1.25

n= 380candy bars

Answer:

x = 3

Step-by-step explanation:

[tex] (3x,\: x +1)=(x_1, \:y_1) [/tex]

[tex] (11,\: 12)=(x_2, \:y_2) [/tex]

[tex]slope = \frac{y_2 - y_1}{x_2 - x_1} \\ \\ 4 = \frac{12 - (x + 1)}{11 - 3x} \\ \\ 4 = \frac{12 - x - 1}{11 - 3x} \\ \\ 4 = \frac{11 - x}{11 - 3x} \\ \\ 4(11 - 3x) = 11 - x \\ \\ 44 - 12x = 11 - x \\ \\ 44 - 11 = 12x - x \\ \\ 33 = 11x \\ \\ x = \frac{33}{11} \\ \\ \huge \red{ \boxed{x = 3}}[/tex]

Answer:

The slope is 3

Step-by-step explanation:

Slope= (y2-y1)/(x2-x1)

(4-1)/(4-3)= 3/1=3

The slope is 3

Answer:

I believe it is 14.

Step-by-step explanation:

Answer: The value of x is 14°

Step-by-step explanation:

Since line m is parallel to n, then then the two given angles will have the same measures. Meaning that 136 degrees has to equation (9x+10).

Set them to equal each other and solve for x.

9x + 10 = 136

    - 10      -10

  9x  = 126

x=  14
