Answer:
D. The rate of change for function B is greater than the rate of change for function A
Step-by-step explanation:
Function a has a slope (aka rate of change) of 3/3
I know this because we start at (-3, 0) then finish at (0, 3)
We added 3 to both the x value and the y value.
3/3 = 1, so we have a rate of change of 1 for function A
Now that we know this, we can write the equation out into slope intercept form.
We can get y = x + 3
The equation for function B is y = 5x + 5
The slope for function B is greater, therefore the rate of change for function B is greater than the rate of change for function A
Find the missing side length of this right triangle
Answer:
41
Step-by-step explanation
because this triangle is a right triangle , u know that u can use pythagorean theroem to solve this.
the pythogorean theroem is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]. the hypotenuse is the longest side or the one that the right angle is pointing to. in the equation , the hypotenuse is represented by c.
so then u juss plug in the numbers that you have so 9 sqaured + 40 squared is equal to c sqaured.
then when you simplify that you end up with 81+1600=[tex]c^{2}[/tex]
then you add the two numbers and you get 1681=[tex]c^{2}[/tex]
u have to get the variable by itself so you find the sqaure root of each side which would look like [tex]\sqrt{1681}[/tex]=[tex]\sqrt{c}[/tex]
simplify that, and you get c=41
hopefully that helped ! :)
Write and equation in slope intercept form to model the situation.
A candle is 8 inches tall and burns at 3/4 inch each hour.
Answer:
The equation that models the situation is [tex]y = 8 - 0.75t[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line, in slope-intercept formula, has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much y changes when x changes by 1 unit) and b is the intercept, which is the value of t when x = 0.
A candle is 8 inches tall and burns at 3/4 inch each hour.
Using t as number of hours and y as the height.
Initial height of 8 inches, that is, when [tex]t = 0, y = 8[/tex], so [tex]b = 8[/tex]
Burns at 3/4 inch each hour.
That is, the height decreases by a rate of 3/4 inch each hour, so [tex]m = -\frac{3}{4} = -0.75[/tex]
So
[tex]y = 8 - 0.75t[/tex]
A circles radius is 13 meters what is the circles area using 3.14 rounded to the nearest tenth
Answer:
530.7
Step-by-step explanation:
A circle's area is defined as πr²
You would substitute 13 in for r (the radius) and use 3.14 as your given value for pi, leaving you with this:
3.14×13²
When you calculate this, it should return a value of 530.66, which rounded to the nearest tenth is 530.7

The function d =
45t gives the distance d Juan traveled in miles after t hours.
is this discrete or continuous data?
Answer:
Continuous data
Step-by-step explanation:
Given
[tex]d = 45t[/tex]
Required
Discrete or Continuous?
From the question, we understand that t represents time in hours. This is a continuous data.
When multiplied by 45 to give distance, the resulting data is also continuous.
Hence, [tex]d = 45t[/tex] is continuous
Answer:
d = 2.5t, continuous

2/3(x+6)=-18 I need the answer help me!!
Answer:
x = -33
Step-by-step explanation:
2/3(x+6) = -18
multiply (x+6) by 2/3
2/3x + 4 = -18
subtract 4 from both sides
2/3x + 4 - 4 = -18 - 4
2/3x = -22
multiply by 3/2
2/3 x 3/2 x = -22 x 3/2
x = -33
Step-by-step explanation:
so we basically simplify the equation to the form, which is simple to understand
2/3(x+6)=-18 then Reorder the terms in parentheses
+( + 0.66666666666667x+4)=-18 after that
Remove unnecessary parentheses
+ 0.66666666666667x+4=-18 then We move all terms containing x to the left and all other terms to the right.
+ 0.66666666666667x=-18-4 so We simplify left and right side of the equation.
+ 0.66666666666667x=-22 We divide both sides of the equation by 0.66666666666667 to get x.
x=-33 get it?
18 less than four times a number is 5.
I think the mathematical equation for this sentence is
(Step 1)
4x-18=5 Add 18 to both sides to get the numbers on the same

4x =23
(Step 2)
4x =23 / 4 Divide equation by four
x=5.75 The answer is X=5.75
Hope I was able to help :)
Answer:
Assuming you wanted to find that mystery number:
It would be 5.75.
Step-by-step explanation:
5 = 4x - 18
Add 18 to both sides of the equation:
5 + 18 = 4x - 18 + 18
23 = 4x - 18 + 18
23 = 4x
Divide each side by 4:
(23/4) = (4x/4)
23/4 = x
5.75 = x
x = 5.75
A motel clerk counts his $10 bills and $20 bills at the end of the day. He finds that he has a total of 150 bills, and that those 150 bills have a total value of $2,000. How many $10 bills and $20 bills does the motel clerk have?
Translate the problem into 2 equations.
Let the x be the number of $10 bills and y be the number of $20 bills.
Answer:
100 $10 bills and
50 $20 bills
Step-by-step explanation:
Given
[tex]x = \$10[/tex]
[tex]y = \$20[/tex]
[tex]Bills = 150[/tex]
[tex]Value = \$2000[/tex]
Required
Determine the number of $10 and $20 bills
[tex]Bills = 150[/tex].
This implies that:
[tex]x + y = 150[/tex]
[tex]Value = \$2000[/tex]
This implies that:
[tex]10x + 20y = 2000[/tex]
So, the equations are:
[tex]x + y = 150[/tex]
[tex]10x + 20y = 2000[/tex]
Make x the subject in the first equation
[tex]x = 150 -y[/tex]
Substitute 150 - y for x in the second
[tex]10(150 - y) + 20y= 2000[/tex]
[tex]1500 - 10y + 20y= 2000[/tex]
[tex]1500 + 10y = 2000[/tex]
[tex]10y = 2000-1500[/tex]
[tex]10y = 500[/tex]
[tex]y =50[/tex]
Recall that:
[tex]x = 150 -y[/tex]
[tex]x = 150 -50[/tex]
[tex]x = 100[/tex]

Measure of Pairs of Angles: Calculate the measure for
160 degrees
or
20 degrees
or
180 degrees
or
90 degrees
The angle vertical to 160 is also 160.
So you have 320
You have 320 out of a full circle, 360.
If there's two angles left, equal to each other
Then they each would be 20 degrees.
I'm not sure what you tried to solve for but I guess this is a simple rundown of the image.
Answer:
The remaining angles are 20°, 160° and 20°
Step-by-step explanation:
Since a circle has 360° and one angle is know, the remaining angles can be found.
Angle U = 160° and the angle in the opposite side must be equal to Angle U so the angle opposite to U is 160° as well.
The remaining two angles are equal to each other and since the total degrees must be 360° and 2 angles are known, we can solve for the remaining angles.
Let's say the remaining angles are values "x".
360° must equals 160° + 160° + x + x
360 = 160 + 160 + x + x
360 = 320 + 2x
40 = 2x
x = 20
The remaining two angles are 20°
how do you know that the expression 2x + 4y is not equivalent to 6xy
Answer:
The expression is not equivalent because you cannot combine 2 variables that are different from eachother.
Step-by-step explanation:
you are able to add 2+4 but because they have variables with them, x and y, you can not add them together.

The perimeter of a rectangular garden is 68 yards. The width of the garden is five yards less than twice the length.
(a) Find the length and width of the garden.
(b) What is the area of the garden?
The length of the garden is
(Type an integer or a decimal.)
The width of the garden is
V (Type an integer or a decimal.)
The area of the garden is
(Type an integer or a decimal.)
Answer:
a. Length = 13 yards and Width = 21 yards.
b. Area of rectangle = 273 square yards.
Step-by-step explanation:
Let the length of the rectangular garden be L
Let the width of the rectangular garden be W
Given the following data;
Perimeter of garden = 68 yards
Translating the word problem into an algebraic equation, we have;
W = 2L - 5 ......equation 1
Note: The formula for calculating the perimeter of a rectangle is;
[tex]P = 2L + 2W[/tex]
68 = 2L + 2W ........equation 2
Substituting eqn 1 into eqn 2;
68 = 2L + 2(2L - 5)
68 = 2L + 4L - 10
68 = 6L - 10
6L = 68 + 10
6L = 78
L = 78/6
L = 13 yards
To find the width;
W = 2L - 5
W = 2(13) - 5
W = 26 - 5
W = 21 yards.
b. To find the area of the garden;
Area of rectangle = length * width
Area of rectangle = 13 * 21
Area of rectangle = 273 square yards.
