Answer:
Y=mx+c
Step-by-step explanation:
The number in front of the x is the gradient. This shows how much the line goes up in the y axis for every square in the x axis. The number after the plus is the y intersect. This is where the line crosses the y axis. Start at the y intersect and draw the line. For this question, the gradient is 2, so the line goes up 2 squares on the y axis for every square on the x axis. The y intersect is 1, so it would cross the y axis at +1 on the y axis

Find g(f(x)), given f(x)=3x2−x+1,g(x)=2x
Answers
Answer:
6x²-2x+2
Step-by-step explanation:
For g(f(x)), we have to first do f(x), and then substitute it into the "x" in g(x)
So, f(x) = 3x²-x+1
We need to substitute the "x" in g(x) with this entire thing
So, g(x) = 2x
When we substitute f(x) into it, it instead becomes 2(3x²-x+1)
Next, we have to expand the brackets, and doing so gives us the following:
6x²-2x+2
So that becomes our final answer!

n
In the figure, lines mand n are parallel to each other. Lines p and q are also parallel to each
m
other. What is the value of x?
Answers
Answer:
80
Step-by-step explanation:
in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x
that is
if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees
since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees
therefore y=100
now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees
that is
x+y=180
we know that y = 100
therefore,
x+100=180
collect like terms and
x = 180-100
therefore,
x= 80

Tina babysits children in her neighborhood. When Tina is asked her rate, she tells her neighbors that she charges $15 for the first hour and $8 for each hour after. If Tina's neighbor asks Tina to babysits for 4 hours, how much will Tina earn? Write an equation to model and solve the problem. Write the answer as an ordered pair and explain the meaning of the ordered pair.
Answers
The amount charged is an illustration of a linear equation.
Tina charges $39 for 4 hours
The given parameters are:
[tex]Base = 15[/tex] --- amount charged for the first hour
[tex]Rate = 8[/tex] --- amount charged for the extra hours
If Tina babysits for 4 hours, it means that:
She will charge $15 for the first hour$8 for the extra 3 hoursSo, the total charges is:
[tex]Total = 15 + 3 \times 8[/tex]
[tex]Total = 15 + 24[/tex]
[tex]Total = 39[/tex]
The ordered pair is (4,39)
It means that:
She charges $39 for 4 hours

The points (6, 9) and (5, 8) fall on a particular line. What is its equation in slope-intercept form?
Answers
Answer:
y=x+3
Step-by-step explanation:
Start with the slope equation [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Since the first point is actually further along the x-axis that x-value becomes [tex]x_{2}[/tex] and its corresponding y-value is [tex]y_{2}[/tex]
[tex]\frac{9-8}{6-5}[/tex]=[tex]\frac{1}{1}[/tex]
The slope for the equation is just one so now find the y-intercept by rearranging the slope-intercept equation.
y=mx+b
y-mx=b
Now Substitute either point in to find b
9-1(6)=b
9-6=b
b=3
Your y-intercept is 3 so now we can write the slope-intercept equation for the two points:

Use the point- slope form:
y - y₁ = m(x - x₁)Substitute know values:
y - 1 = 1/2(x - 5)The matching choice is C
The correct equation which represents a line that passes through (5, 1) and has a slope of 1/2 is,

How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
There are 16 cups in a gallon, and if each person will eat 2 cups, and there are 24 people, multiply 24 by 2 to get the number of cups.
24 x 2 = 48.
Then, divide that by 16 (the number of cups in a gallon) to how many gallons.
48 ÷ 16 = 3
Therefore, he needs 3 gallons.

What is the slope?
Answers
Answer:
The slope is 4 or 4/1.
Step-by-step explanation:
Since these are all in numbers evenly divisible by 10, we can go ahead and make this easier by dividing everything by 10. When we do this, we can see a point crossing an intersection at (3,1), or if you left it, (30, 10). Next, we can see another point crossing another intersection at (4,5) or (40, 50). Since we have two points that are easy for us to subtract, we can use the slope formula. The formula is as follows: y2-y1 / x2-x1. We can pick which of these we want to be 1 or 2, but whichever one we pick has to be 1 or two on both the top on the bottom. for example, I did (50-10) / (40-30). That gets us 40/10. If you divided by ten in the first place, you would get 4/1. From there, if you have the bigger answer, you need to simplify to simply 4. The shorter answer doesn't need to be simplified because we already simplified. I hope this helps!

No, 5x+y^2=25 is not a linear equation.
What is termed as the linear equation?A linear equation is one in which the variable's highest power is always 1. A one-degree equation is another name for it. A linear model in one variable has the standard form Ax + B = 0. In this equation, x is a variable, A is a coefficient, and B is constant. A linear equation throughout two variables has the standard form Ax + By = C.For the given equation;
5x+y^2=25
the highest power of the equation is 2.
Thus, the given equation is a quadratic equation or 2 degree equation.

what is the GCM of 9 and 7
Answers
Answer: See explanation
Step-by-step explanation:
Do you mean the greatest common factor (GCF), or the lowest common multiple (LCM).
If you mean GCF, then it is 1 because 7 is a prime number and has two facotrs (1 and itself) and since 9 isn’t divisible by 7, the GCF must be 1.
If you mean the LCM, the answer is 63. Using prime factorisation, we find the lowest prime factor of both numbers:
9 = 3^3
7= 7^1
Then, we multiply these together to give 63.
You cannot have a GCM, because you can’t find a greatest common multiple as numbers go on forever.
