Step-by-step explanation:
f(x) = 3x - 4
g(x) = -2x + 7
= (fog)(2)
= 3(-2x + 7) - 4
= 3(-2.2 + 7) - 4
= 3(-4 + 7) - 4
= 3(3) - 4
= 9 - 4
= 5
(fog)(x) = 5
Is the following number rational or irrational?
0.4
——
0.8
Choose 1 answer:
Rational
or
Irrational
0.4/0.8
= 4/10 × 10/8
= 4/8
= 1/2
= 0.5
0.5 is a RATIONAL number (A).
=》0.5 is a rational number because it's in the form of p/q (5/10) where both p & q are integers & q is not equal to 0.
=》 Also, q can be expressed in the form of 2ⁿ × 5ᵐ (q = 10 = 2¹ × 5¹) which makes it a rational number.

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (−2, 4)?
y = – Five-halves x – 1
y = – Five-halvesx + 5
y = Two-fifthsx – 1
y = Two-fifthsx + 5
Answer:
First, let’s rearrange the equation in terms of y:
y = -2.5x + 6
We can input the coefficient of x (the gradient of the line) above into this equation:
y - y1 = m (x - x1)
Where y1, is the y value of an arbitrary point in the line, m is the gradient of the line, and x1 is the corresponding x value of the same arbitrary point in the line for y1.
So, putting it in we get:
y - 4 = -2.5(x +2)
y -4 = -2.5x - 5
y = -2.5x -1

3 1/2 divided by 2 3/5
Answer:
26/35
Step-by-step explanation:
1. First to divide the 3 1/2 by 2 3/5 you have to turn them both into improper fractions
First take 3 1/2. You have to multiply the whole number (3) by the denominator (2) and you would get 6. Then you would add then you add the product (6) to the numerator (1) and get 7.
You keep the denominator the same so the improper fraction is 7/2
Do the same thing to 2 3/5 and the improper fraction is 13/5
2. Now we can divide 13/5 by 7/2 using "keep, change, flip"
Keep: 13/5
Change: division to multiplcation
Flip: 7/2 to make 2/7
Your new equation is 13/5 × 2/7. Multiplcation is easy so you just have to multiply staight across: 13 × 2 and 5 × 7 giving you 26/35
If you divide 35 by 26 you will get 1.34 and a bunch of other numbers but I usually stop at two decimal places

A camera has a listed price of $750.99 before tax. If the sales tax rate is 8.25% find the total cost of the camera with sales tax included. Round your answer to the nearest cent, as necessary.
Answer:
we get $812.95: total cost
Step-by-step explanation:
The sales tax on this $750.99 camera is found as follows: 0.0825($750.99) = $61.96. Adding this amount to the $750.99 price, we get $812.95: total cost.
A faster way to calculate the total cost is to multiply $750.99 by (1.0825): again we get $812.95
Find the slope of each line please help
Answer: The slope should be 2/3
Step-by-step explanation: Slope is rise over run. Remember you always rise before you run. So in this case you start at the origin and go up until you get to the point on the line where the line is centered. You go up 3 times and thats where the first actual point is. Then move to the side until you get to the line which is 2 to the right. so therefore your answer is 3/2
what is the initial value of the graph?
Answer:
The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y- value of the point at which the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope. Which statement best describes a geometric sequence?

gimme brainliest
Answer:
54 degrees
Step-by-step explanation:
You can just do 90-36 to get your answer for this one, since it is a right angle.
90-36=54
so it would be 54 degrees
UNIT RATE: TRUE OR FALSE?
Answer:
False
Step-by-step explanation:
A unit rate has to have a denominator (the number below the fraction bar) of 1. It can't have, as in this problem, a denominator of 2. If this were an actual unit rate, it would look more like this: [tex]\frac{25ft}{1sec}[/tex]. Hopefully that's helpful! :)
1/5
of a
number is 105
Answer:
525
Step-by-step explanation:
Let the number be " x ".
1 / 5 of x is 105
x / 5 = 105
x = 105 x 5
x = 525
Therefore,
the number is 525.
Answer:
525Step-by-step explanation:
1/5 of a number is 105, and the number is
105 * 5 = 525

b) Use the graph to estimate the value of x when y= 1
9514 1404 393
Answer:
see attached for a graph
x = 0.5 when y = 1
Step-by-step explanation:
The graph has a y-intercept of -1, which is halfway between 0 and -2. It goes up 4 units (2 vertical grid spaces) for 1 unit to the right (1 horizontal grid space). It seems to cross y = 1 at about x = 1/2.
x = 1/2 when y = 1.

How many solutions can be found for the system of linear equations represented on the graph?
A) no solution
B) one solution
C) two solutions
D) infinitely many solutions
Answer:
A) No solution
Step-by-step explanation:
Given the systems of linear equations, y = 2x + 1 and y = 2x - 1:
Both equations in the system have the same slope, m = 2, thus forming parallel lines. Since their lines are parallel from each other, then it means that their lines will never intersect.
Therefore, the given systems of linear equation is an inconsistent system that has no solution.
which choices are correct when determining the distance between 73 and -51 on a number line
Answer:
124
Step-by-step explanation:
73 to 0 is 73
0 to -51 is -51 hence
(+73)-(-51)
124
the distance between 73 and -51 on a number line is 124 units.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the distance between 73 and -51 on a number line
Let the distance between 73 and -51 on a number line be [ΔN]. Then, we can write -
N{1} = 73
N{2} = - 51
ΔN = |N{2} - N{1}|
ΔN = |-51 - 73|
ΔN = |- 124|
ΔN = 124
Therefore, the distance between 73 and -51 on a number line is 124 units.
