Answer:

x=-4 and x=3

Step-by-step explanation:

If y=0, then we use the Zero Product Property:

0=(x+4)(x-3)

x+4=0

x=-4

x-3=0

x=3

Given:

A video game customers to rent games for $4.75 each.

Customers can also buy a membership for $54 annually, and video games would only cost $2.50 each.

To find:

The number of video games a customer would have to rent in a year in order for the two options to be equal.

Solution:

Let x be the number of video games.

A video game customers to rent games for $4.75 each. So, the total cost is

[tex]C_1(x)=4.75x[/tex]

Customers can also buy a membership for $54 annually, and video games would only cost $2.50 each. So, the total cost is

[tex]C_2(x)=54+2.50x[/tex]

Now, [tex]C_1(x)=C_2(x)[/tex], if the rent in a year for the two options to be equal.

[tex]4.75x=54+2.50x[/tex]

[tex]4.75x-2.50x=54[/tex]

[tex]2.25x=54[/tex]

Divide both sides by 2.25.

[tex]x=\dfrac{54}{2.25}[/tex]

[tex]x=24[/tex]

Therefore, the rent in two options are equal for 24 video games.

Answer:

x = -3

y = 9

Step-by-step explanation:

you can add the equations after multiplying the first one by 8

8x - 8y = -96  added to -8x - 4y = -96

'x' eliminated;  -12y = -108;  y = 9

Solve for 'x':

x - 9 = -12

x = -12 + 9

x = -3

Answer:

[tex]\displaystyle 0.285=\frac{57}{200}[/tex]

Step-by-step explanation:

Decimal to Fraction Conversion

We have the decimal number 0.285

It can be expressed as:

[tex]\displaystyle 0.285=\frac{285}{1000}[/tex]

The fraction can be simplified by dividing by 5:

[tex]\displaystyle 0.285=\frac{57}{200}[/tex]

Since 57 and 200 have no more common factors, this is the simplified equivalent fraction.

[tex]\mathbf{\displaystyle 0.285=\frac{57}{200}}[/tex]

u know the sinus theorem for the area of a triangle

u can search it sinus theorem triangle

for the solution:

12.4/sin(74)=y/sin(39)

y=7.85 cm

Answer:

Length y is 8.12cm

Step-by-step explanation:

Use the law of sines.

[tex]\frac{sin(a)}{A} =\frac{sin(b)}{B}[/tex] ⇒[tex]\frac{sin(39)}{y} =\frac{sin(74)}{12.4}[/tex]

[tex]y(\frac{sin(39)}{y}) =y(\frac{sin(74)}{12.4})[/tex]

[tex]sin(39)=y(\frac{sin(74)}{12.4})[/tex]

[tex]y=\frac{sin(39)}{sin(74)/12.4}[/tex]

[tex]y=\frac{12.4*sin(39)}{sin(74)}[/tex]

y=8.118052433 if you don't round.

Answer:

Baxter runs 3/2 lengths of the backyard per minute.

Step-by-step explanation:

The question is asking how many times Baxter runs the length of the backyard per minute. We know that he runs 3/4 of the backyard every 1/2 of a minute. This means that he runs 6/4 (simplified to 3/2) per minute.

Answer:

10.5

Step-by-step explanation:

You can use ratios to solve this problem.

The original dimensions of the photo is

5 in. by 7 in.

This can be written as:

5:7

And the next is 7.5:?

Then you can use ratios to solve this.

5:7=

7.5:?

5*1.5=7.5 so you can multiply the other side by the same thing. 7*1.5=10.5

The width is 10.5 inches.

Answer:

The square root of 65

Step-by-step explanation:

Using the formula A squared B squared = C Squared

Thus, c equals the square root of 65

Answer:

12

Step-by-step explanation:

12+12=12 and 12 = 12 and 9+10= 21

Given:

Cory made 21 of the 60 baskets she attempted.

Krista made 16 out of 40 baskets she attempted.

Paul made 17 of the 50 baskets she attempted.

Sally 11 of the 55 she attempted.

To find:

Who had the greatest percentages of baskets made?

Solution:

We know that,

[tex]\text{Percentage of baskets made}=\dfrac{\text{Baskets made}}{\text{Total attempts}}\times 100[/tex]

Using this formula, we get

[tex]\text{Cory's percentage of baskets made}=\dfrac{21}{60}\times 100=35\%[/tex]

[tex]\text{Krista's percentage of baskets made}=\dfrac{16}{40}\times 100=40\%[/tex]

[tex]\text{Paul's percentage of baskets made}=\dfrac{17}{50}\times 100=34\%[/tex]

[tex]\text{Sally's percentage of baskets made}=\dfrac{11}{55}\times 100=20\%[/tex]

From the above percentages 40% is maximum.

Therefore, Krista has greatest percentage of baskets made.

Answer:

Step-by-step explanation:

Answer:

B) 0.4 (6 - 2w)

Step-by-step explanation:

You can only add or subtract with the numbers that have the same variable:

You can only add -2.2w and 1.4w

Which is -0.8w

Then add 4.8 and -2.4

Which is 2.4

Now the equation is -0.8w+2.4 or 2.4-0.8w

0.4 times 6 is 2.4

0.4 times 2w is -0.8w

Which is the same

-0.8w+2.4 or 2.4-0.8w

Hope this helps!

Answer:

The average rate of change of the function for the interval [-4, 0] is  [tex]\frac{3}{4}[/tex] ⇒ A

Step-by-step explanation:

The average rate of change of the function is the slope of the line that represents the function, m = Δy/Δx, where

From the given figure

→ The values of x in the interval [-4, 0] are -4 and 0

∵ The point (-4, 0) and (0, 3) lie on the line

∴ x1 = -4 and x2 = 0

∴ x2 = 0 and y2 = 3

∵ Δx = 0 - (-4) = 0 + 4 = 4

∵ Δy = 3 - 0 = 3

→ By using the rule of the slope above

∴ m = [tex]\frac{3}{4}[/tex]

∵ The average rate of change of the function = the slope of the line

∴ The average rate of change of the function for the interval [-4, 0] is  [tex]\frac{3}{4}[/tex]
