Answer:
B
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 8x + 2
f(x) * g(x) = (3x - 7)(8x + 2) {Use FOIL method}
= 3x*8x + 3x *2 +(-7)*8x + (-7)*2
= 24x² + 6x - 56x - 14 {Combine like terms}
=24x² - 50x - 14
What is 6x + 8y = 60 and 3x - 4y = -18

The ratio of marbles to stones in a large pot is 6 to 7. If there are 42 marbles, then how many stones are there?
Answer:
49 stones
Step-by-step explanation:
Write the following proportion based on the given ratio of marbles (m) to stones (s), and naming the unknown number of stones to find, with the letter "X":
6 m / 7 s = 42 m / X s
cross multiply to get the unknown in the numerator:
6 * X = 42 * 7
divide both sides by 6 to isolate X entirely on the left of the equal sign
X = ( 42 * 7 ) / 6
X = 49
Therefore, there are 49 stones

A tank has 120 gallons of water and is being drained at a rate of 12 gallon each second. Another tank has 100 gallons of water and is being drained at a rate of 14 gallon each second. Which equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water? Multiple choice question.
The equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water is 120-1/2x = 100-1/4x
What is meant by equation?There are many different ways to define an equation. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
Various kinds of equations: Algebraic math equations include the following.
Equation with Lines;
More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.
Equation in QuadratureThis equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.
Cubic FormulaA third-order equation is this one. At least one of the variables in cubic equations needs to be increased to exponent 2
Given ,
tank 1 = 120 - 1/2x
tank 2 =100 - 1/4x
Therefore 120-1/2x = 100-1/4x
So we can conclude that the equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water is 120-1/2x = 100-1/4x
The complete question is: A tank has 120 gallons of water and is being drained at a rate of 12 gallon each second. Another tank has 100 gallons of water and is being drained at a rate of 14 gallon each second. Which equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water? Multiple choice question.
120x + 1/2 = 100x + 1/4
120 + 1/2x = 100 + 1/4x
120x - 1/2 = 100x - 1/4
120 - 1/2x = 100 - 1/4x

Y=6x-3 function rule
Answer:
f(x) = 6x - 3
Step-by-step explanation:
what's the value of y ?
[tex]y = ( { - 2 })^{2} [/tex]
-2x+2y=6 and 7x+4y=23
Let's solve this problem step-by-step:
Let's set:
[tex]-2x + 2y = 6 -- equation 1\\7x+4y=23 -- equation 2[/tex]
(equation1) * 2
[tex]-4x+4y=12--equation3[/tex]
(equation 2) - (equation 3)
[tex]11x = 35\\x= \frac{11}{11}--equation4\\x=1[/tex]
Plug (equation4)'s value of 'x' into (equation1)
[tex]-2(1} )+2y=6\\-2+2y =6 \\2y = 6+2 =8 \\y =4[/tex]
Thus x= 1 and y = 4
Let's check:
[tex]-2(1 )+2(4)=6\\2 +4 =6\\6=6\\ \\7(1)+4(4) )=23\\7+16=23\\ 23 =23\\[/tex]
Answer: x = 1 and y= 4

On Monday you read 3 pages.
Tuesday, 3 times that number on Monday,
Wednesday is 3 times the number on Tuesday.
How many pages do you read on Wednesday? (Hint: 38)
pages
Answer:
27 pages
Step-by-step explanation:
Since you read 3 pages on Monday and you read 3 times that number on Tuesday, the equation should be 3*3 to equal 9. Then, since you read 9 pages on Tuesday and 3 times that number on Wednesday, the equation should be 9*3 to equal 27 pages. So, on Wednesday, you read 27 pages in total.
Answer:
27 pages
Step-by-step explanation:
Monday=3 pages
Tuesday=3 pages × 3
=9 pages
Wednesday=9 pages × 3
=27 pages
