Answer:

a scale factor of 2.5

Step-by-step explanation:

if this was area, you would square. Therfore if it is only perimeter so you only have to multiply by the same number

Answer:

vertex = (- 1, 3 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = 2x² + 4x + 5 ← is in standard form

with a = 2, b = 4, then

[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1

Substitute x = - 1 into the equation for corresponding value of y, that is

y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3

vertex = (- 1, 3 )

Answer: -6

Step-by-step explanation:

since they are both negative, they both will add up to be -6

Answer:

my brain just died sorry

Step-by-step explanation:

Answer:

x = 6

4x2−10x=84

Step 1: Subtract 84 from both sides.

4x2−10x−84=84−84

4x2−10x−84=0

Step 2: Factor left side of equation.

2(2x+7)(x−6)=0

Step 3: Set factors equal to 0.

2x+7=0 or x−6=0

x=

−7

2

or x=6

Answer:

1435.00

Step-by-step explanation:

dusted 2 hours. 15.00

Scrubbed floors 142 hours= 1420.00

Answer:

$30

Step-by-step explanation:

10$ x  1.5 (hours)  = 15$ (the reason i did 1.5 is because she scrubbed for 1 and a half hours)

$7.50 x 2 (hours) = $15

$ 15 + $15 = 30

she earned $30 dollars

Answer:

7 hours

Step-by-step explanation:

2 divided by 14

i hope this helped

Answer:

7 hours

Step-by-step explanation:

Answer:

36.7

Step-by-step explanation:

Since 33 is 90% of a number, you can divide 33 by 9 to get 3 2/3. This 3 2/3 is 10% of the number, so multiply 3 2/3 by 10 to get 36 2/3. 36 2/3 rounded to the nearest tenth is 36.7, so there's your answer. Hope it helps!

Answer:

I think the answer is 169

Answer:

140

Step-by-step explanation:

x = 7  ; y = -2

7(2x - 3y) = 7(2*7 - 3*[-2])

               = 7(14 + 6)

              = 7 * 20

               = 140

Step-by-step explanation:

this is what I believe the answer is and the work for it

Step-by-step explanation:

2,4,5 (actual answer)

2-angle MNP (38) is less than angle ONP (39)

4- they are equal by the reflexive property of congruence op

5-is MNP has a lower angle, side MP should have a longer side

Answer:

it would be right next to the other line

Step-by-step explanation:

Answer:

5 over 8

Step-by-step explanation:

convert the mixed numbers to improper fractions then divide them and simplify

equation: 7/2 ÷ 40/7 = 50/80 or simplify to 5/8

*the slash is supposed to be the line that separates the top and bottom number in the fraction*

Answer: Vertical angles

Step-by-step explanation:

Answer:

Vertical Angles

Step-by-step explanation:

Vertical angles are "any opposite pairs of angles made by intersecting lines."

Also, if 2 angles are vertical, they are also congruent.

Answer:

I= $3,000

Step-by-step explanation:

Giving the following information:

Klein opened a savings account that paid 5% simple interest with 6,000 in principal.

Number of periods= 10 years

To calculate the interest earned, we need to use the following formula:

I= P*r*t

P= principal

r= interest rate

t= time

I= 6,000*0.05*10

I= $3,000

Answer:

Step-by-step explanation:

4

Answer:

280 seats total

Step-by-step explanation:

90/100 = 252/x

To find x, cross multiply.

90x = 25,200

Divide both sides by 90 to get the variable alone.

x = 280 seats

Answer:y=-x=5

Step-by-step explanation:

Answer:

You first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.

Step-by-step explanation:

Answer:

below

Step-by-step explanation:

improper fraction: 14/5

as a decimal: 2.8

proper fraction: 2 4/5

We need to solve both for y.

#9:

[tex]y - 4 = 3(x - 1)\\\\y - 4 = 3x - 3\\\\y = 3x + 1[/tex]

#10:

[tex]y - 1 = -4[x - (-3)]\\\\y - 1 = -4(x + 3)\\\\y - 1 = -4x - 12\\\\y = -4x - 11[/tex]
