PLZZZZZZZZZ HEEELPPPPPPPPP MEEEEE

Answer:

y = 17/2

Step-by-step explanation:

7y − 4 = 9y + 13 − 4y

Simplify both sides of the equation.

7y - 4 = 5y + 13

Subtract 5y from both sides.

2y - 4 = 13

Add 4 to both sides.

2y = 17

Divide both sides by 2.

y = 17/2

I hope this helps! Feel free to ask any questions!

Answer:

Step-by-step explanation:

y = a(x-4)^2 + 4

Plug in (2,-8) and solve for a:

-8 = a(2-4)^2 + 4

a = -3

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

Step-by-step explanation:

Answer:

(-2,4), (0,4), (-4,-2) and (2,-2)

Step-by-step explanation:

Given

[tex]A = (-5,9)[/tex]

[tex]B = (-2,9)[/tex]

[tex]C = (-8,0)[/tex]

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

[tex]Translation: 2\ units\ right\ \& \ 3\ units\ down[/tex]

[tex]Dilation: \frac{2}{3}[/tex]

Required

Determine the vertices of the image RSTU

When a coordinate (x,y) is translates b units right, the new coordinate is: (x + b, y)

So, translation 2 units right gives:

[tex]A = (-5,9)[/tex] ---> [tex]A' = (-5 + 2,9) = (-3,9)[/tex]

[tex]B = (-2,9)[/tex] ---> [tex]B' = (-2 + 2,9) = (0,9)[/tex]

[tex]C = (-8,0)[/tex] ---> [tex]C' = (-8 + 2,0) = (-6,0)[/tex]

[tex]D = (1,0)[/tex] --- > [tex]D' = (1 + 2,0) = (3,0)[/tex]

When a coordinate (x,y) is translates b units down, the new coordinate is: (x, y-b)

So, translation 3 units down gives:

[tex]A' = (-3,9)[/tex] ---> [tex]A" =(-3,9-3) =(-3,6)[/tex]

[tex]B' = (0,9)[/tex] --> [tex]B" =(0,9-3) =(0,6)[/tex]

[tex]C' = (-6,0)[/tex] --> [tex]C" =(-6,0-3) = (-6,-3)[/tex]

[tex]D' = (3,0)[/tex]--> [tex]D"=(3,0-3) = (3,-3)[/tex]

Lastly, dilation of 2/3 gives:

[tex]New = Old * \frac{2}{3}[/tex]

[tex]R = (-3,6) * \frac{2}{3} = (-2,4)[/tex]

[tex]S = (0,6) * \frac{2}{3} = (0,4)[/tex]

[tex]T = (-6,-3) * \frac{2}{3} = (-4,-2)[/tex]

[tex]U = (3,-3) * \frac{2}{3} = (2,-2)[/tex]

Hence, the coordinates of RSTU are: (-2,4), (0,4), (-4,-2) and (2,-2)

Answer:

[tex]\frac{13}{\sqrt{2}}[/tex] or 9.19 (approximately). I am confused how the question is asking for it to be typed, so it might be this: [tex]\frac{13}{\sqrt{2}}[/tex] , but if you cannot type that in, then maybe it is sin(45) * 13.

Step-by-step explanation:

The three main trigonometric ratios are: sine (o/a), cosine (a/h), or tangent (o/a) depending on the given. To help you remember them, you can use the saying SOH CAH TOA, which is sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/adjacent.

     In this problem, we are going to use one that has the hypotenuse, which rules out tangent, and leaves us with sine or cosine. Since, we are given the hypotenuse and the opposite side (from angle 45), we will be using sine. Then we just need to set up the trigonometric ratio:

sin (45) = x/13  

Then, you need to get x by itself, so you multiply 13 on each side, which leaves you with:  

x = sin(45) * 13 = 9.19 (approximately)

This could also be seen as a special right triangle, where the hypotenuse is [tex]x\sqrt{2}[/tex], and the two sides are x.

So, to find the value of x, you could also do this: 13/[tex]\sqrt{2}[/tex], which might be how the question wants it formatted.

Good luck!

Answer:

14

Step-by-step explanation:

divide by 10

Answer:

14

Step-by-step explanation:

You have the proportion:

3 cm: 30 millimeters

divide both sides by 3

1 cm: 10 millimeters

Then, multiply both sides by 14

14cm: 140 millimeters

So 14 centimeters are in 140 millimeters

Answer:

Answer: 1.32 x 10^4

Step-by-step explanation:

Answer:

122

Step-by-step explanation:

The total surface area is 122. This is because 7 times 4 equals 28. Then you do 7 times 5 twice, which makes 35 times 2, which makes 70. This is because there are 2 triangles with 7 as the base and 5 as the height. Next, you do 4 times 3 twice, which equals 12 + 12 which adds up to 24. Now add the numbers up. 70 + 28 + 24, which = 122.

It's been about a few years since I did area and circumference, if this is the wrong answer I apologize!

Answer:

B!

Step-by-step explanation:

we know that (x-5) and (y-6) must add up to 129 because 180-51 is 129

now let's plug in the values to see

51-5= 66 63-6 = 57

57+66 is 123, not this one, let's repeat the same step

77-5 is 72, 63-6 is 57, these added is 129

Answer:

A function will not have any repeating x values...it can have repeating y values, just not the x ones. So all ur x's have to be different.

Answer: 45 = 5t

Step-by-step explanation:

From the question, Jamahl wants to celebrate his birthday by roller skating with his friends and he has a total of $45dollar to buy t tickets.

We are further told that the ticket costs $5. The equation that matches the situation will be:

45 = (5 × t)

45 = 5t

t = 45/5

t = 9

He can buy 9 tickets

THANK YOU....

PLZZ GIVE ME A BRAINLIEST TAG

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]

it is given that

area of the rectangle = y

width of the rectangle = x

so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]

perimeter = 64

Perimeter is the sum of all four sides of the rectangle.

we can say that,

2(length + breadth) = 64

[tex]2( \frac{y}{x} + x)=64\\\\[/tex]

[tex]\frac{y}{x} + x= 32[/tex]

[tex]\frac{y + x^{2} }{x} = 32[/tex]

[tex]y+x^{2} = 32x[/tex]

[tex]y = -x^{2} +32[/tex]

therefore, the expression for the area of the rectangle,

[tex]y = -x^{2} +32[/tex]
