Li believes that the graph shows a direct variation. On a coordinate plane, a line goes through points (0, 1) and (2, 0). Why is Li incorrect in saying that the graph shows a direct variation? The graph does not have a constant rate of change. When the x-value is 0, the y-value is 1. The slope is negative. The relationship is proportional.
Answer
B) When the x-value is 0, and the y-value is 1
Step-by-step explanation:
Edge
When the x-value is 0, the y-value is 1.
Which graph shows a direct variation?A relationship between two variables, x, and y, symbolizes a proportional variation if it can be described in the form y/x = k or y = kx.
In a proportional relationship, the constant of proportionality k exists equivalent to the slope m of the line and the line passes through the origin.
Recognize that in a direct variation
For x=0, the value of y exists equivalent to zero.
Therefore, the graph exists not have a direct variation, because
When the x-value exists at 0, the y-value exists at 1.

1. The measures of two angles are (5x + 24) and (9x - 17). What is the value of xif these
angles are congruent?
Answer:
x = 41/4
Step-by-step explanation:
If the angles are congruent, then the equation are congruent.
Step 1: Set up equation
5x + 24 = 9x - 17
Step 2: Solve for x
24 = 4x - 1741 = 4xx = 41/4Find the student’s error in solving the following inequality. 31 < –5x + 6 25 < –5x –5 < x The student should have added 6 to both sides instead of subtracting it. The student divided 25/–5 incorrectly. The student should have switched the direction of the inequality sign to get –5> x for a final answer.

You made two deposits to your bank account this month. One deposit was $17.92, and the second deposit was $15.33. Your balance at the end of the month is $72.31, and you made no withdrawals. Write and evaluate an expression for your balance at the beginning of the month.
A. $72.31 – ($17.92 – $15.33); $69.72
B. $72.31 + $17.92 + $15.33; $105.56
C. $72.31 + ($17.92 – $15.33); $74.90
D. $72.31 – $17.92 – $15.33; $39.06
Answer:
D. $72.31 – $17.92 – $15.33; $39.06Step-by-step explanation:
Initial amount is x
Deposits made:
$17.92$15.33Total amount is:
x + $17.92 + $15.33 = $72.31Balance at the beginning of the month
x = $72.31 - ($17.92 + $15.33) = $39.06Option D is correct

Jade used candle molds, as shown, to make candles that were perfect cylinders and spheres: A cylindrical mold is shown, the radius of the top circular section of the cylinder is labeled 3 inches and the height of the cylinder is labeled as 7 inches. On the right side of this mold is a spherical mold. The radius of this spherical mold is labeled as 3 inches. What is the approximate difference in the amount of wax needed to make a candle from each of these molds? (Use π = 3.14.)
Answer:
[tex]Difference = 85\ in^3[/tex]
Step-by-step explanation:
Given
Cylinder:
[tex]Height = 7\ inches[/tex]
[tex]Radius = 3\ inches[/tex]
Sphere
[tex]Radius = 3\ inches[/tex]
Required
Determine the difference in amount of wax needed in both
To do this, we first calculate the volume of both
[tex]Volume_{cylinder} = \pi r^2h[/tex]
[tex]Volume_{cylinder} = 3.14 * 3^2 * 7[/tex]
[tex]Volume_{cylinder} = 3.14 * 9 * 7[/tex]
[tex]Volume_{cylinder} = 197.82\ in^3[/tex]
[tex]Volume_{sphere} = \frac{4}{3}\pi r^3[/tex]
[tex]Volume_{sphere} = \frac{4}{3} *3.14 * 3^3[/tex]
[tex]Volume_{sphere} = \frac{4}{3} *3.14 * 27[/tex]
[tex]Volume_{sphere} = 113.04\ in^3[/tex]
Then calculate the difference:
[tex]Difference = Volume_{cylinder} - Volume_{sphere}[/tex]
[tex]Difference = 197.82in^3 - 113.04in^3[/tex]
[tex]Difference = 84,78in^3[/tex]
[tex]Difference = 85\ in^3[/tex] -- Approximated

jacob went to the gas station with $17.70. He bought a drink for $2.90, and he wanted to spend the rest of his money on a bag of chips for his friend which costs $1.85 each. What is the maximum number of bags of chips that he can buy? Define a variable then write and solve an inequality.
Answer:
He can buy 8 bags of chips.
Step-by-step explanation:
first create a equation:
drink's cost + bag of chip's cost(number of chips) = total
2.9 + 1.85x = 17.7
17.7 is the total, 2.9 is the cost of the drink, 1.85 is the cost of a bag of chips, and x is the number of chips.
Solve for x:
2.9 + 1.85x = 17.7
-2.9 -2.9
1.85x = 14.8
1.85 1.85
x = 8
Check:
12.9 + 1.85(8) = 17.7
12.9 + 14.8 = 17.7
17.7 = 17.7

Answer:
x = 28
66°
Step-by-step explanation:
[tex] \because \overrightarrow{XZ} [/tex] is the bisector of [tex] \angle WXY[/tex]
[tex] \therefore m\angle WXZ = m\angle ZXY\\
\therefore (2x + 10)\degree = (3x - 18)\degree \\
\therefore 2x + 10 = 3x - 18\\
\therefore 2x - 3x = - 18 - 10\\
\therefore - x = - 28\\
\huge \purple {\boxed {\therefore x = 28}} \\\\
\because m\angle ZXY= (3x - 18)\degree\\
\therefore m\angle ZXY= (3\times 28- 18)\degree\\
\therefore m\angle ZXY= (84- 18)\degree\\
\huge \orange {\boxed {\therefore m\angle ZXY=66\degree}} \\[/tex]

6x-9=4x-15 fill in the blank math ? please help
Answer:
x = -3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do t one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
Isolate the x. First, add 9 and subtract 4x from both sides:
6x (-4x) - 9 (+9) = 4x (-4x) - 15 (+9)
6x - 4x = -15 + 9
Combine like terms:
6x - 4x = -15 + 9
2x = -6
Next, divide 2 from both sides of the equation:
(2x)/2 = (-6)/2
x = -6/2
x = -3
x = -3 is your answer.
~
Important things to note:
- PEMDAS is the order of operation, and equals Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.
- If there is an equal sign and the same variable on both sides, you are trying to isolate that variable.
- Remember to follow the division rule. If you are dividing two negative numbers, your answer will be positive. If you are multiplying two negative numbers, your answer will be positive. If you are dividing or multiplying one positive and one negative number, your answer will be negative.

Nancy has eleven credit cards. She pays an annual fee of $45 each for the use of two of the cards, a $35 annual fee for use of three of the cards, and a $30 annual fee for the use of four of the cards. The remaining two cards do not have an annual fee. How much should she budget each month to pay her annual fees on the eleven credit cards?
$25.00
$25.75
$26.25
$27.00
None of these choices are correct.
Answer:
$26.25
Step-by-step explanation:
I multiply each fee with the number of cards it goes along with, then I added it up all together which is 315. To get the monthly fee I divide 315 by 12 to get the answer.
45(2)+35(3)+30(4)
90+105+120 = 315
315/12 = 26.25
