Answer:

y= 10x+50

Step-by-step explanation:

x is an increasing variable so, if 10 members are joining each month, x equals 10. 50 is a non increasing number so it has no variable. and y equals all members in total, so y= 10x+50

Answer:

y=2x

Step-by-step explanation:

compute the slope  first-

(-2,1) and (2,9)

m = 9-1/2-(-2) = 8/2+2= 8/4 = 2

knowing the slope take a given point  and substitute  it's x and y values into the equation to solve for 'b' the y-intercept-

y = mx + b,

1 = 2(-2) + b,

1 = -4+ b,

b = 5

our  equation is  y = 2x + 5

if you want an equation parallel  to the line  it  has to have the same slope. Take y = 2x

Answer: y=2x+5

Step-by-step explanation:

To find line a in slope-intercept form, we first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]m=\frac{9-1}{2-(-2)} =\frac{8}{4}=2[/tex]

Now that we know the slope, we can plug in any point to find the y-intercept.

y=2x+b       [plug in any point]

9=2(2)+b    [multiply]

9=4+b         [subtract both sides by 4]

b=5

The final equation is y=2x+5.

The quotient is 21. the correct answer is option 1) 21.

To find the quotient of 189 divided by 9, we divide 189 by 9.

When dividing 189 by 9, we find that 9 can be subtracted from 189 a total of 21 times without going into negative values. Therefore, the quotient is 21.

So, the correct answer is option 1) 21.

When we divide 189 by 9, the result is 21, which means that 21 is the number of times that 9 can be subtracted from 189 without remainder. The quotient represents the whole number part of the division, indicating the number of groups of 9 that can be formed from 189.

Answer:

false

Step-by-step explanation:

this is showing 2/-3

Answer: False.  

Step-by-step explanation:

The slope is the difference in the y coordinates of any two points being divided by the difference between the x coordinates of the same two points.

Using the point,  (0,5) and (3,3)  find the difference in the y coordinates and divide it by the difference in the x coordinates to find the slope.

y:  5 - 3 = 2  

x :  0 - 3 = -3

Slope:  -2/3

This is indeed true because line is going downright  so the slope has to  be negative.

Answer:

y = 50x + 100 this is the equation.

It would take her 10 months, since she already has 100.

Step-by-step explanation:

600 - 100 = 500

500/ 50 = 10

Problem 8

The triangles are congruent, which means their corresponding pieces must also be congruent.

Focus on the second equation above. We can further say

angle B = angle E

E = B

12x+30 = 50

12x = 50-30

12x = 20

x = 20/12

x = 10/6

----------------

Now move to the equation involving C and F to get

F = C

(y/2) - 10 = 40

y/2 = 40+10

y/2 = 50

y = 2*50

y = 100

----------------

And finally,

D = A

sqrt(z) = 90

z = 90^2

z = 8100

=======================================================

Problem 11

The radius of the circle is r = 5.

The area of the circle is A = pi*r^2 = pi*5^2 = 25pi

The diameter of the circle is 2*r = 2*5 = 10, which is the side length of the square because the circle is fit perfectly inside the square.

Since the square side length is 10, the area is 10^2 = 100

Subtract the two areas: large-small = square - circle = 100 - 25pi

We subtract the areas because we're basically kicking out the circle area when we don't shade it. Think of it like sawing out that portion of a wooden block perhaps.

=======================================================

Problem 19

Part (a)

The point P is directly below the center and it is on the circle.

The location of point P is (18,0) because the x coordinates of both points are the same (so that P is directly below the center) and P resides on the x axis. All points on the x axis have y coordinate 0.

------------------------------

Part (b)

The radius of the circle is r = 10 which is the distance from the center to point P.

The area of the circle is therefore A = pi*r^2 = pi*10^2 = 100pi

Answer: 100pi

Answer:

x + 2x = 9

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Since we are using substitution, we must replace one variable in 1 equation as the 2nd equation.

We are given:

y = 2x

x + y = 9

Here we see that y equals 2x. We can go ahead and replace in the 2nd equation y.

x + 2x = 9

And we would solve from there.

Answer:

SAS

Step-by-step explanation:

If you flip the first triangle right side up, we can see that they are congruent in the same exact spots. The two sides are congruent, as well as the angle.

Answer:

They are congurrent by SAS criterion. SAS stands for side-angle-side where the angle is in between the 2 lines. In this we can see that 2 lines have been marked as well as the angle in both triangles. SAS is a valid criterion for proving congrurency and therefore these are congurent.
