Step-by-step explanation:

[tex]5x+x^2-2x+x^2\\ \\ 2x^2+3x\ or\ x(2x+3)[/tex]

Answer:

5

Step-by-step explanation:

Answer:This is a linear equation.

y = mx+b

y is the total cost.

The slope m is the rate: that's 9 dollars per hour.

x is the number of hours.

b is the initial value: that's 16 dollars.

y = 9x+16

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x

x = 7 hour

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

80-17=63

63/7  = 9

7 times 9 = 63

Kindly check explanation

Step-by-step explanation:

If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong

3 * 9 = exactly 27

However, for approximation sake ;

We could round 9 to 10 ; and multiply 10 by 3

10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;

3 * 9 = exactly 27 or approximately 30

Answer:

Y = 5 - 2/x

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

Answer:

hi

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The answer is D. Y = 63 + 2 = 65

The given equation is y = x + 2, the height is given as 63. The height is the x value so you would replace x in the equation with 63 and solve for y.

Answer:

m∠TUW  = 38°

m∠WUV  =  12°

m∠TUV  =  103°

Hope it helped :)

Answer:

yes

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

All you need to do is solve for x and y because the intersection of both lines will only have one intersection.

since both equations are equal to y then you can set them equal to each other:

7x+8=x+1

6x=-7

x=-7/6

then inset back into y=x+1

y=-7/6+1

y=1/6

so that is the only point of intersection of the lines and it cannot be (3,8)

Hope that helps :)

Answer:

For every miles, the rover gains 12,000 miles

Step-by-step explanation:

I was able to determine this by looking at the graph and determining what the difference between the points. When I found out the each 2 miles is 24,000, i divided 24,000 by two find the unit rate.

Answer:

[tex](\frac{3}{2},102)[/tex]

Step-by-step explanation:

Given

[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question

Required

The symmetry

First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]

Where the symmetry is: (h, y) and x = h

Equate f(x) to 0

[tex]88x^2-264x+300 = 0[/tex]

Subtract 300 from both sides

[tex]88x^2-264x+300 - 300= 0 - 300[/tex]

[tex]88x^2 - 264x= - 300[/tex]

Factorize

[tex]88(x^2 - 3x) = -300[/tex]

On the left-hand side, the coefficient of x is -3.

Divide by 2 and add the square to both sides.

So, we have:

[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]

Multiply the new terms by 88 (to make it factorizable)

[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]

Factorize

[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]

The quadratic expression in the bracket is a perfect square. This gives:

[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]

[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]

[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]

[tex]88(x - \frac{3}{2})^2 = -102[/tex]

Add 102 to both sides

[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]

[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]

Equate to y

[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]

Recall that:

The symmetry is: (h, y)

By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h

[tex]h = \frac{3}{2}[/tex]

So: [tex]x = \frac{3}{2}[/tex]

Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]

[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]

[tex]y = 88(0)^2 +102[/tex]

[tex]y = 0 +102[/tex]

[tex]y = 102[/tex]

So, the symmetry is: [tex](\frac{3}{2},102)[/tex]

Answer: Yes

Step-by-step explanation:

From the question, we are informed that Ed's birthday is less than 16 days

away and that Ann writes the inequality

d< 16, where d equals the number

of days, to represent this.

The inequality d < 16 is correct as it explains that the number of days left is less than 16.

Answer:

Ann is correct because d is less than 16.

Step-by-step explanation:

Ed's Birthday is *less than 16* days away so d<16
