will the point (2, 6) be on the graph of y=3x
Answer:
the answer is yes it will
Answer:
yes
Step-by-step explanation:
since (x,y) is 2,6, we can take x as 2 and y as 6. For the answer to be yes, y=3x must be equal to the x and y values. Lets plug in the values. Is (6)=3(2)?
3 times 2 is 6! So the answer is yes.
Simplify: A. 35/6 B. 29/6 C. 12/5 D. 1/6
Answer:
[tex] \frac{49 - 3}{6} + \frac{24 - 17}{3} = \frac{46}{6} + \frac{7}{3} = \frac{46 + 7 \times 2}{6} = \frac{60}{6} = 10[/tex]

Matthew is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 2 points. What would be Matthew's test score (out of 40) if he got 9 questions wrong? What would be his score if he got xx questions wrong?
Answer:
22 points
Step-by-step explanation:
If their are fourty points avaliable and each question is worth two points, then there are a total of twenty questions (20 times 2 is 40). Therefore, if he gets nine questions wrong, he would have gotten 11 right. Because we know that each question is two points, we may just multiply 11 by 2, which means he has gotten a score of 22 points!

[tex]4\frac{1}{3}[/tex]
Step-by-step explanation:
Apply PEMDAS order of operations:
→ Parentheses
→ Exponents
→ Multiplication
→ Division
→ Addition
→ Subtraction
________________
[tex]\frac{3}{5}+2^2-\frac{2}{5}\left(8-6\right)\div \:3=4\frac{1}{3}[/tex]
1) Parentheses:
[tex]\left(8-6\right)[/tex]
[tex]8-6[/tex]
[tex]=2[/tex]
[tex]\frac{3}{5}+2^2-\frac{2}{5}\times \:2\div \:3[/tex]
2) Exponents:
[tex]2^2[/tex]
[tex]=4[/tex]
[tex]\frac{3}{5}+4-\frac{2}{5}\cdot \:2\div \:3[/tex]
3) Multiplication/Division:
[tex]\frac{2}{5}\times \:2\div \:3[/tex]
[tex]\frac{2}{5}\times \:2[/tex]
Convert to fraction:
[tex]2=\frac{2}{1}[/tex]
[tex]\frac{2}{5}\times \frac{2}{1}[/tex]
Multiply 2 × 2, and 5 × 1:
[tex]=\frac{4}{5}[/tex]
[tex]\frac{4}{5}\div \:3[/tex]
Convert to fraction:
[tex]3=\frac{3}{1}[/tex]
[tex]\frac{4}{5}\div \frac{3}{1}[/tex]
Apply fraction rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
[tex]\frac{4}{5}\times \frac{1}{3}[/tex]
Multiply 4 × 1 and 5 × 3:
[tex]\frac{4}{15}[/tex]
[tex]\frac{3}{5}+4-\frac{4}{15}[/tex]
4) Addition/ Subtraction:
[tex]\frac{3}{5}+4[/tex]
[tex]=\frac{23}{5}[/tex]
[tex]\frac{23}{5}-\frac{4}{15}[/tex]
[tex]=\frac{13}{3}[/tex]
Finally, Convert fraction to mixed number:
[tex]\frac{13}{3}=4\frac{1}{3}[/tex]

What is thissss someone help
Answer:
1. Neither
2. Odd
3. Odd
4. Even
Step-by-step explanation:
Graphically, an equation is even if it is symmetrical across the y-axis. An equation is odd if it is symmetrical after folded over y and x. An equation is neither if it fulfills neither requirement.
Algebraically, an equation is even is f(x) = f(-x), and an equation is odd if f(-x) = -f(x).
Hope it helps :) and let me know if you want me to elaborate.
100 POINTS AND BRAINLIEST!!
Answer:
A. $47,143
Step-by-step explanation:
Given information:
Current annual lifestyle cost ≈ $33,000Take home pay estimation = 70%Gross income: Total income before any deductions.
If take home pay is approximately 70% of the annual gross income, to be able to maintain the current lifestyle, 70% of the annual gross income needs to be at least $33,000.
Let x = annual gross income
Therefore:
70% of x = $33,000
⇒ 0.7x = 33000
⇒ x = 33000 ÷ 0.7
⇒ x = 47142.8571...
Therefore, the annual gross income needs to be $47,143 (nearest dollar) to maintain the current lifestyle.
Annual gross income be y
70% of y=330000.7y=330007y=330000y=330000/7y=47143Option A
How can I find 75% of any number?
Answer:
75% can be converted into a decimal, any percentage can.
Once converted, 75% is actually .75
At this point you can move the decimal place two place up, and put it over 100, in a fractal form
75/100
You can then simplify this to
3/4
You can then use this fraction as a conversion factor with any number, for example if we took the number 8
8∗3/4
2∗3/1=6
Someone pleaseee help me out with this question!!!

Can you help me find the missing sides and calculate the perimeter?
The bottom side is 1m and the side on the right is 2m because looking at the other sides all of the sides should be 10.
Step-by-step explanation:
A rectangle has a perimeter of 36 cm. Its width is 4 cm less than its length. Find
the length and width of the rectangle.
Answer:
14
Step-by-step explanation:
Perimeter = 2 x length + 2 x width = 2L + 2w
Width is 4 cm less than the length, so w = L-4
36 = 2L + 2(L-4)
36 = 2L + 2L - 8
36 = 4L - 8
44 = 4L
L = 11
w = 7
2(11) + 2(7) = 22 + 14 = 36
Length is 11, width is 7
Double the product of eight and a number
Answer:
Oh ok
Step-by-step explanation:
An expression is defined as a set of numbers, variables, and mathematical operations. The given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Let the unknown number be represented by x.
The product means multiplication, therefore, we need to double or multiply the product or multiplication of eight and x.
Thus, The given statement in the form of an expression can be written as,
2(8 × x)
= 2(8x)
= 16x
Hence, the given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.

Solve for n: 9^(n-1) = (1/3)^(4n-1) Show your work.
Answer:
n=1/2 after being simplified
Step-by-step explanation:
Use Division Distributive Property:
9^n-1=1/3^4n-1 then convert both sides to the same base
3^2(n-1) = 3^-(4n-1)
cancel the base of 3 on both sides
2(n-1) = -4n+1
then expand 2n-2=-4n+1
add 2 to both sides 2n=4n+1+2
simplify: -4n+1+2 to -4n+3
2n=-4n+3
add 4n to both sides: 2n+4n=3
simplify: 2n+4n to 6n
6n=3
divide both sides by 6
n=3/6
simplify and n=1/2

Which one of the following values of k makes the trinomial 9x^2 + kx + 64 a perfect square
a 24
b 48
c 16
d 42
Answer:
it is C 16
Step-by-step explanation:
x² - kx + 64
Since we are looking for a perfect square, then we need to take the square root of 64 to find the factors: √64 = 8
So, the factors are: (x - 8)(x - 8)
Foil (or distribute) to get: x² - 16x + 64 The k-value is 16
