Answer:

8

Step-by-step explanation:

x=7

7+1=8

Answer:

8

Step-by-step explanation:

x=7 so, it would be 7+1=8

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:

(x-2)^2= - 8(y-6)

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: z = -2

Step-by-step explanation:

6z + 10 = -2

add 10 on both sides

6z = -2 -10

6z = - 12

divide 6 on both sides

z = -2

Answer:

z= -2

Step-by-step explanation:

6z+10=-2

-10. -10

6z = -12

÷6. ÷6

z= -2

Step-by-step explanation: 73+242 = 315

Answer: 315

Step-by-step explanation: 73+242=315

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.

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:

B :)

Step-by-step explanation:

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]

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

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]
