Answer:
D
Step-by-step explanation:
To find out whether a graph is a function or not, you can use the vertical line test, which means if you were to draw a vertical line on the graph at any point, if it would cross over 2 lines, it's not a function. D is the only graph that wouldn't fail the vertical line test.

Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the graph of the given equation.
Equation: y-intercept of 1, 3x – y = 5
Answer:
The equation is [tex]y=-\frac{1}{3}x+1[/tex]
Step-by-step explanation:
You have the y-int, so you just need to find the slope, which is the negative reciprocal of A/B since it is perpendicular. Plugging in the numbers gets you the above equation.
The volume of a rectangular prism is 240 cm3. The height and width are each 4 cm. What is the length?
Answer:
length is 15 cm
Step-by-step explanation:
4 * 4 * x = 240
16x=240 : divide by 16 on both sides
x = 15
then to check
15 cm x 4 cm x 4 cm = 240 cm^3
An umbrella at a shop was marked for $6 . During a sale, a discount of 10% was given. A further 8% discount was given to the senior citizens. How much would a senior citizen need to pay for the umbrella during the sale? Round your answer to the nearest cent.
Answer:
A senior citizen will pay $4.97
Step-by-step explanation:
Mathematically, discount = discount percentage * marked price
Sales price = marked price - discount
In the question, marked price = $6
First, we have a discount of 10%, so therefore , the sales price will be;
$6 - (10/100 * $6 ) = $6 - $0.6 = $5.4
Now, a further 8% discount was given to senior citizens,
The extra discount for senior citizens is thus;
8/100 * 5.4 = $0.432
Amount to be paid by senior citizens = $5.4 - $0.432 = $4.968. which is $4.97 to the nearest cent
Answer:
the answer is $4.97.

help me plz lol
Answer:
4 [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
When adding fractions, you want to make the denominators of the fraction the same. To do this, we can multiply both the numerator and denominator of 3/4 by 3. When changing either a denominator or numerator in a fraction, you must do the same thing to the numerator as the denominator.
Now we have [tex]\frac{3\cdot3}{4\cdot3} = \frac{9}{12}[/tex]. To add 9/12 and 5/12, we keep the denominator the same, and add the numerators, getting [tex]\frac{9+5}{12} =\frac{14}{12}[/tex]. This is greater than 1, so we can take 12/12 from 14/12, and make it [tex]1 \frac{2}{12}[/tex]. If we then add 3, we get [tex]4 \frac{2}{12}[/tex], which simplifies to [tex]4 \frac{1}{6}[/tex]

Given problem:
What is the value of x = ?
Solution:
Angle on a straight line is 180°
Sum of angles in a triangle = 180°
Now to solve the problem, we need to find the two internal angles first;
For the first one;
let us say it is y;
163 + y = 180
y = 180 - 163 = 17°
For the second, assume it is z;
69 + z = 180
z = 180 -69 = 111°
The sum of the internal angles of the triangle;
y + z + 2x = 180
17 + 111 + 2x = 180
2x = 180 - 128
2x = 52
x = [tex]\frac{52}{2}[/tex] = 26
The value of x is 26

157 is 16.6% of what number
157 = .166 x
157/0.166 = x
945.78313253 = x
157 is 16.6% of 945.78313253, which rounds to 946.
The 157 is approximately 16.6% of 945.78313253012 rounded to the nearest decimal place.
To find the number that 157 is 16.6% of, set up the following equation:
16.6% = 0.166 (since percentages expressed as decimals)
0.166 × x = 157
To isolate x, we divide both sides of the equation by 0.166:
x = 157 / 0.166
Simplifying the division:
x ≈ 945.78313253012

the length of a side of a square is 8x+4.If the perimeter of the square is 80 inches, what is they value of x?
Answer:
Step-by-step explanation:
Note: Perimeter = sum of all the lengths of the shape.
In the case of a square, since all the sides are equal.
This means that if one side = 8x + 4, the perimeter would be 4 times 8x+4 since there are 4 equal sides in a square.
Perimeter = 4 ( 8x + 4)
Perimeter = 32x + 16
We also get told in the question that the perimeter = 80 inches.
Meaning that:
32x + 16 = 80
From here we can solve for x.
Subtract 16 from both sides:
32x = 80 - 16
32x = 64
Divide both sides by 32 to solve for x.
x = 64/32 = 2

What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28
Answer:
y = -1/4x + 4
Step-by-step explanation:
x+4y=28
4y = -x + 28
y = -1/4x + 7
slope m = -1/4
Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.
y = mx +b
2 = -1/4(8) + b
2 = -2 + b
b = 4
Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.
y = mx + b
y = -1/4x + 4
