[tex] \frac{7}{2} x + 16 = 30[/tex]

Answer:

x=16

Step-by-step explanation:

11×9=99, so variaton is 9x=y. that means y=x/9

144/9=16

01921

Step-by-step explanation:

3,4,5 is correct

as we know that ,

3² + 4² = 5²

9 + 16 = 5²

25 = 25

hence . 3,4,5 is correct

Answer:

I'm pretty sure it's 3,4,5 but I'm not sure (is it in cm,mm etc?)

Answer:

A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is (5 ) units. the point (-7, -1) and point (-7, 5) lies in this circle.

Step-by-step explanation:

equation of circle is

(X-center_X)^2 + (y-center_Y)^2 = r^2

==> (x+3)^2 + (y-2)^2 = r^2

Now it passes 1,5 so

4^2+3^2 = 5^2

==> r = 5

when x = -7

y = -1 or 5

Answer:

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)

Step-by-step explanation:

Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are

(x - 3) and (x + 5)

The equation is the the product of the factors, that is

y = a(x - 3)(x + 5)  ← a is a multiplier

To find a substitute (- 1, 8) into the equation

8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )

- [tex]\frac{1}{2}[/tex] = a

Then

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form

Answer:

Find the variables first, you will have to find the segments by measuring between the whole degree which is, 180 degree.

Step-by-step explanation:

Multiply each side and divide the variable and you will find the answer for each side. Then, add all of them.

Answer:

The slope is 1/5.

The slope means that the puppy's weight is slowly increasing over time.

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

then the answer is None of the above

-2.724

4.361+1.9328i

4.361+1.9328i

Answer:

-13

Step-by-step explanation:

f(x)=2x-7

f(-3)=2(-3)-7=-6-7=-13

Step-by-step explanation:

Given

f(x) = x + 5

Let

y = f(x)

y = x + 5

Interchanging the roles of x and y we get

x = y + 5

y = x - 5

f^-1 (x) = x - 5

Answer:

8 dimes and 14 quarters.

Step-by-step explanation:

d and q are the number of dimes and quarters, respectively.

"22 coins, all dimes and quarters"

d+q = 22

d = 22-q

"total value is $4.30"

0.10d + 0.25q = 4.30

substitution

0.10(22-q) + 0.25q = 4.30

2.2 + 0.15q = 4.30

q = 14

d = 22-q = 8

8 dimes and 14 quarters.

Answer:

y = 4

Step-by-step explanation:

20 = 5y

then divide both side by 5

20 ÷ 5 = 4

so y is 4

Answer:

350

Step-by-step explanation:

Answer:

C. 350 pounds

Step-by-step explanation:

Looking at the chart, week 22 would be between the week 20 and week 25 marks. As a result, the weight should be between 275 and 425 pounds. As a result, A is out. Week 22 will be bigger than week 20 (275), so B is also out. Week 22 is in between Week 20 and 25, so it isn't bigger than Week 25's pumpkin; D is out for this reason. That leaves C, 350 pounds, as our answer.

Answers + Explanation:

1. x + 7 =10

if you know some number + 7 is 10, you know that number must be 3.

so, x = 3

the other way you can solve this would be:

x + 7 = 10

subtract 7 from both sides of the equation

x + 7 - 7 = 10 - 7

x = 3

2. Use the same strategy:

x - 8 = -5

add 8 to both sides of the equation

x - 8 + 8 = -5 + 8

x = 3

3. x + 3 = 6

subtract 3 from both sides of the equation

x + 3 - 3 = 6 - 3

x = 3

4. x + 6 = 3

subtract 6 from both sides of the equation

x + 6 - 6 = 3 - 6

x = -3

Answer:

x = 3

y = 4

Step-by-step explanation:

2x +  y = 10          -----------------(I)

     y = x + 1 ---------------------(II)

Substitute y = x + 1 in equation (I)

2x + x + 1 = 10    {Combine like terms}

      3x + 1 = 10         {Subtract 1 from both sides}

             3x = 10 -1

             3x = 9 {Divide both sides by 3}

                x = 9/3

x = 3

Plugin x = 3 in equation (II)

y = 3 + 1

y = 4
