Answers

Answer:

Jasmine can afford 10 ounces of yogurt and toppings.

Step-by-step explanation:

$7 - $2.50 bottle of water

= $4.50

$4.50 divided by $0.45

= 10 ounces

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.

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.

Solving systems of equations using substitution/elimination

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.

PLEASE HELP!!!!! 1.) Line a passes through points (-2, 1) and (2, 9). Write an equation in slope intercept form that is parallel to line a. 40POINTS

Answers

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.

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,

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

Find the quotient: 189 divided by 9
1. 21
2. 22
3. 23
4. 24

Answers

3 is the correct answer

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.

The equation y-2= 5/4 (x + 8) represents the cost (in dollars) of making your own fruit juice (fluid ounces) a. What is the slope of the line? Interpret the slope in the context of this situation. b. Write the equation as a linear function (simplify to slope- intercept form). c. Use the linear function in part (b) to determine the base cost of making your own fruit juice.

Answers

Answer:

a. The slope is 5/4

b. The equation in slope and intercept form is y = 5/4·x + 12

c. The base cost of making a fruit juice is $12

Step-by-step explanation:

The equation that gives the cost in dollars of making your own fruit juice is given as follows;

y - 2 = 5/4·(x + 8)

a. The slope = The coefficient of x = 5/4

The slope = 5/4

b. The equation can be presented in slope and intercept form, y = m·x + c, as follows;

y - 2 = 5/4·(x + 8)

y = 5/4·x + 10 + 2

y = 5/4·x + 12

c. The base cost of making a fruit juice = The cost added to any quantity of fruit, x made = The y-intercept, c = 12

The base cost of making a fruit juice = $12.

Answer:

a. The slope is 5/4

b. The equation in slope and intercept form is y = 5/4·x + 12

c. The base cost of making a fruit juice is $12
