4x = 2(x-5)-2 can you solve please

Answer:

y = -13

I like two step equations

Step-by-step explanation:

Equation :

18 = 5-y

Im just going to flip it around because it feels more comfortable

5-y = 18

Add y to both sides

5 = 18 + y

Subtract 18 from both sides

-13 = y

y = -13

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Answer:

the circumference is the total distance round a circle but the are is a measure of a space or region inside the circle but circumference is around it

Answer:

(2, 5)

Step-by-step explanation:

The longest side of the triangle will be the side with the coordinate (1,4) and (3,6) due the value of the distance between them;

Midpoint = (x1+x2/2, y1+y2/2)

X = 1+3/2

X = 4/2

X = 2

Y = 4+6/2

Y = 10/2

Y = 5

Hence the required midpoint (X, Y) will be at (2, 5)

Answer:

57 miles per hour

Step-by-step explanation:

Find his average speed by dividing the total of miles he traveled by the number of hours:

456/8

= 57

So, this means he traveled 57 miles in one hour.

His average speed was 57 miles per hour

Answer:

[tex]C = (1,0)[/tex]

[tex]E = (0.8,0)[/tex]

See attachment for C and E

Step-by-step explanation:

Given

[tex]O= (0,0)[/tex] --- Origin

[tex]CO = 1[/tex] --- distance of C to O

Solving (a): Plot point C

Calculate the coordinates of C using distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]

Where:

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (x,y)[/tex] -- [tex](x_2,y_2)[/tex]

[tex]d = CO = 1[/tex]

So, we have:

[tex]1 = \sqrt{(x - 0)^2 + (y -0)^2}[/tex]

[tex]1 = \sqrt{x^2 + y^2}[/tex]

Square both sides

[tex]1^2 = x^2 + y^2[/tex]

[tex]x^2 + y^2 =1[/tex]

For this solution, we assume y = 0

[tex]x^2 + 0^2 =1[/tex]

[tex]x^2=1[/tex]

Solve for x

[tex]x = 1[/tex]

So, the coordinates of C is: (1,0)

[tex]C = (1,0)[/tex]

Solving (b): Plot point E

We have that E is 4/5 closer to the origin.

This implies that, the ratio is:

[tex]m : n = 4/5:1/5[/tex]

Multiply by 5

[tex]m : n = 4:1[/tex]

So, E is at 4:1 between O and C

Calculate the coordinates of E using:

[tex]E = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]

Where

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (1,0)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]m : n = 4:1[/tex]

[tex]E = (\frac{4*1 + 1 * 0}{4 + 1},\frac{4*0 + 1*0}{4 + 1})[/tex]

[tex]E = (\frac{4}{5},\frac{0}{5})[/tex]

[tex]E = (0.8,0)[/tex]

Q: You are shot out of a cannon at the fair. The equation y=-1/5 * (x+2) (x-28) models your flight path, where y is the height above the ground and x is the horizontal distance. Which of the following statements in the comments are true?

a) You reach a maximum height of 45 feet,

b) You will land 11.2 feet from the cannon,

c) The barrel of the cannon is about 11 feet above the ground.

d)At a point 13 feet from the cannon, you begin to descend.

A: When y = 0, x = 28

y’ = 0 at x = 13 where Y is max = 15^2 / 5 = 45

Hence a is true, b is false, c is false, d is false .

Answer:

Option A

Step-by-step explanation:

Land area of Charlotte, NC = [tex]3\times 10^2[/tex] square miles

Scale to be used,

1 square miles = [tex]6.4\times 10^2[/tex] square acres

By this scale,

[tex]3\times 10^2[/tex] square miles = [tex](6.4\times 10^2)\times(3.2\times 10^2)[/tex] square acres

                                  = [tex](6.4\times 3)\times 10^{2+2}[/tex]

                                  = [tex]19.2\times 10^4[/tex] square acres

                                  = [tex]1.92\times 10^5[/tex] square acres

Therefore, Option A will be the correct option.

Answer:

10/13

Step-by-step explanation:

You will first add all the students the mentioned which gives you 13 then since they ask what is the probability it the teacher would pick girls. You know there's 10 girls and 3 boys so it would be 10/13.

Answer:

$144

Step-by-step explanation:

Volume of the pyramid = 1/3BH

Base area B = 1/2 * 6 * 4

Base area B = 12 ft²

Height H = 4ft

Volume of the pyramid = 12 * 4

Volume of the pyramid = 48ft³

SInce 1 ft³ = $3

48ft³ = x

Cross multiply

x = 3 * 48

x = 144

Hence the cost of the sign is $144

Answer:

x = 9

y = [tex]9\sqrt{2}[/tex]

Step-by-step explanation:

Since there is a 45° angle and a 90° angle, this is a isosceles triangle, therefore x = 9 and you can find y by pithagoras:

9² + 9² = y²

81 + 81 = y²

y = [tex]\sqrt{162}[/tex]

[tex]y=\sqrt{2 * 81}[/tex]

[tex]y=\sqrt{2 * 9^2}[/tex]

[tex]y=9\sqrt{2}[/tex]
