Ohio Skate charges a flat fee of $60 for skating parties plus $6 per person. Matteo can spend no more than $126 on his skating party.
Which number line represents the number of people Matteo can invite to his skating party without exceeding his spending limit

Answer:

(- 2, 15 ) and (2, 7 )

Step-by-step explanation:

Given the 2 equations

y = 3x² - 2x - 1 → (1)

2x + y = 11 → (2) ← subtract 2x from both sides

y = 11 - 2x → (3)

Substitute y = 3x² - 2x - 1 into (3)

3x² - 2x - 1 = 11 - 2x ( subtract 11 - 2x from both sides )

3x² - 12 = 0 ( add 12 to both sides )

3x² = 12 ( divide both sides by 3 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

Substitute these values into (3) for corresponding values of y

x = - 2 : y = 11 - 2(- 2) = 11 + 4 = 15 ⇒ (- 2, 15 )

x = 2 : y = 11 - 2(2) = 11 - 4 = 7 ⇒ (2, 7 )

Answer:

3x+y+11=0 ans

Step-by-step explanation:

given question;(-5,4) is (x1,y1) and m=slope=-3

then, using formula

y-y1=m(x-x1)

y-4=-3(x+5)

y-4=-3x-15

3x+y+11=0 ans

Answer:

It is B

The slope of the line that passes through the point (3, -10.5) and (7.-28.5) will be -5

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

The slope of the line is calculated as follows:

m = Δy/Δx

Given that the line that passes through the points (3, -10.5) and (7.-28.5)

To find the slope of the line that passes through points (3, -10.5) and (7.-28.5).

Therefore, the slope of the line is;

m = Δy/Δx

m = (-28.5- 10.5)/(7 - 3)

m = -20/4

When we simplify it, then we get;

m = -5

Hence, the slope of the line is -5.

Answer:

105 children

Step-by-step explanation:

35/100×300

105

Answer:

Option (2)

Step-by-step explanation:

Formula for c the cost of a painter is,

c = 20h + 35

Here, h = hours the painter worked

If a homeowner has total amount $125 to spend on painting,

So, for c = 125,

125 = 20h + 35

(20h + 35) - 35 = 125 - 35

20h = 125 - 35

[tex]\frac{20h}{20}=\frac{(125-35)}{20}[/tex]

h = [tex]\frac{(125-35)}{20}[/tex]

Therefore, Option (2) will be the answer.

Answer:

$1954

Step-by-step explanation:

Given the profit function expressed as;

y=-3x^2 + 197x – 1279

The profit is at maximum when dy/dx = 0

dy/dx = -6x + 197

0 = -6x+197

6x = 197

x = 197/6

x = 32.83

substitute 32.83 into the modeled function

y=-3x^2 + 197x – 1279

y -3(32.83)²+197(32.83) - 1279

y = -3(1,078.03)+6,467.51 - 1279

y = -3,234.09+6,467.51-1279

y = 1,954.42

hence the maximum amount of profit the company can make, to the nearest dollar is $1954

Similar figures have corresponding angles that are congruent.

Step-by-step explanation:

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion. In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Given:

Fractions [tex]\dfrac{1}{9},\dfrac{2}{9},\dfrac{3}{9}[/tex] etc.

To find:

What happens with the “ninth” fractions.

Solution:

We have, the values of [tex]\dfrac{1}{9},\dfrac{2}{9},\dfrac{3}{9}[/tex] are

[tex]\dfrac{1}{9}=0.11111...[/tex]

[tex]\dfrac{2}{9}=0.22222...[/tex]

[tex]\dfrac{3}{9}=0.33333...[/tex]

Clearly we can spot a pattern, because after decimal the numerator digit of fraction is repeating.

Similarly,

[tex]\dfrac{9}{9}=0.99999...[/tex]

Therefore, the decimal value of [tex]\dfrac{9}{9}[/tex] is 0.99999..., which is approximately 1.

Answer: With the range between each, the times it ran first was 1, and the water was 0.5. Then, the times was 2, and the water level was 1. It's adding .5 to the level of water every minute.

Time Water Runs              Level of Water

         1                                       1.5

         2                                      3.0

Answer:

The value of a that can substituted into equation D = 4b + 5

Step-by-step explanation:

Given that:

a = 4b + 5   ---- (equation c)

a = 6b - 2   ---- (equation d)

Replace the value of a = 4b + 5 into "a" in (equation d) to solve the system of equations.

So;

4b + 5 = 6b -2

5 + 2 = 6b -4b

7 = 2b

b = 7/2

b = 3.5

Answer:

The correct answer is 4b + 5 ( A )

Answer:

769.69 (769.7 Rounded)

Step-by-step explanation:

V=πr^2h=π·7^2·5≈769.6902

Answer:

(-1) degrees

Step-by-step explanation:

∵ Temperature drop with the increase in every 1000 ft of height = 2 degrees

∴ Temperature drop in every 1 ft = [tex]\frac{2}{1000}[/tex] degrees

∴ Temperature drop in 29000 ft = [tex]\frac{2\times 29000}{1000}[/tex]

                                                      = 58 degrees

Temperature on ground = 57 degrees

Temperature at 29000 feet = 57 - 58

                                               = -1 degrees

Therefore, temperature at 29000 feet is -1 degrees.

Answer:

The answer is 15 - p = k

     Since the temperature dropped 7 degrees, we will subtract 7 degrees from the original temperature given.

Write an equation to represent the situation:

37°F - 7°F = x

What was the temperature after the sun went down:

37°F - 7°F = x

30°F = x

        The temperature after the sun went down was 30°F.

Answer:

-84i - 12i

Step-by-step explanation:

The distributive property is: a(b+c) = ab + ac

In this case, we have -6i(-14i+2)

-6i = a

-14i = b

2 = c

-6i(-14i+2) = -6i(-14i) + -6i(2)

= 84i^2 - 12i

= -84 - 12i

Answer:

84-12i

Step-by-step explanation:

-6i(-14i+2).

since we can’t add the numbers in the (), we multiply -6i to 14i and 2.

minus times minus equals positive +.

minus times positive equals minus, same with positive times minus.

positive times positive numbers equal positive.

with this, -6i times -14i equals +84 although we don’t need to put the +.

then -6i times +2 equals -12i. We have to put the i in 12i because the i is in -6i, plus that is what we are multiplying with. So the equation would be..

+84+(-12i)

= 84 - 12i
