The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
The slope of f(x) is equal to the slope of g(x). The y-intercept of f(x) is less than the y-intercept of g(x).
The slope of f(x) is equal to the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
PLS HELP
Answer:
The slope of f(x) is equal to the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
Step-by-step explanation:
F(x) is already given to you on the graph. You need to plot the x and g(x) graph. (remember g(x) is just a fancy way of saying y)
Once this line is plotted, you will see that f(x) and g(x) are parallel to one another. G(x) is below f(x), so its y-intercept is lower.

Original grade:80
New grade:100
Find the precent of increase
Answer:
25%
Step-by-step explanation:
because from 80 to 100 is 20 and 20 is 1/4 of 80 and 1/4 to a decimal is .25
Answer:
80/100. That's 20% increase. When you hadd 8 and 2 you get 10.

Find the x- and y-intercepts of : 4y-6x = 24
Answer:
x-intercept: (-4, 0)
y-intercept: (0, 6)
Step-by-step explanation:
4y - 6x = 24
To find the x-intercept, set the y value equal to 0.
4(0) - 6x = 24
Simplify by removing 4(0) since it just equals 0.
-6x = 24
Divide both sides of the equation by -6
x = -4
Since we set y equal to 0 and we know that the x value is -4, we can create a coordinate for the x-intercept of the equation.
(x, y) = (-4, 0)
Repeat the process for finding the y-intercept, but set x equal to 0.
4y - 6(0) = 24
4y - 0 = 24
4y = 24
Divide both sides of the equation by 4
y = 6
Write as a coordinate/intercept.
(x, y) = (0, 6)

Answer:
S = 180C²
18,000 lbs
Step-by-step explanation:
Assuming the table attached with C in inches and S in pounds, we see that the first differences in S are ...
180, 540, 900
These are not constant, so the relation is not linear.
Second differences are ...
360, 360
These are constant, so the relation is quadratic. With a short trial, we find that a suitable equation is ...
S = 180·C²
__
The safe load for C=10 is then ...
S = 180·10² = 18,000 . . . pounds

Jake earns $8 per hour for cutting grass. If he works a 35-hour week,
how much money will he earn?
There are many ways to solve these types of questions. But I am going to use the fraction method.
Step 1: Set up a fraction.
Setting up a fraction, given the question will be the units on the same level. And the money earned will be a variable, "[tex]m[/tex]". It does not matter whether they are top or bottom.
[tex]\frac{8}{1} = \frac{m}{35}[/tex]
Step 2: Solve
[tex]\frac{8}{1} = \frac{m}{35}[/tex]
Multiply 35 to both sides[tex]\frac{35m}{35}=8\cdot \:35[/tex]
[tex]m=280[/tex]
Therefore, Jake will earn $280.

A gym employee earns the same amount each month. After working for three months, he earned $4,500. Complete the table to determine how much money he will make over a five-month period. 5.Is the relationship proportional? Explain your thinking.
Answer:
1,500
Step-by-step explanation
1. to divide 3 by 4,500.
after dividing 3 and 4,500 you get
1,500
The money he will make over a five-month period will be $7,500.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A rec center worker procures a similar sum every month. In the wake of laboring for a considerable length of time, he procured $4,500.
The amount of money that he earns each month is given as,
⇒ $4,500 / 3
⇒ $1,500 per month
Then the money he will make over a five-month period will be given as,
⇒ $1,500 x 5
⇒ $7,500
The money he will make over a five-month period will be $7,500.
More about the ratio and the proportion link is given below.

help please this is timed i’m not sure if my answer is correct
(it’s abt perpendicular, parallel and skew lines)
Answer:
Perpendicular
Step-by-step explanation:
Both lines intersect and form a right angle when they intersected each other. Non co-planar means essentially means "on different planes", but both lines do lie on the same plane. Parallel lines don't intersect at all! However lines a and d are intersecting. Skewed means neither parallel nor perpendicular (meaning they intersect and don't form a right angle).
Answer:
It would be perpendicular.
Step-by-step explanation:
Perpendicular lines form a 90-degree angle.
Skew lines are on different planes and do not intersect.
Since A and D intersect with a 90-degree angle they're perpendicular.

Go to your math tools and open the Graph tool to graph the equation you found for calculating profit. Set the scale of the graph to go from -5 to 40 on the x-axis and from -80 to 80 on the y-axis.
Part A
What do the points on the line in quadrant IV represent in terms of the situation?
Answer:
The y-coordinates in quadrant IV are negative. Because y represents profit, negative values of y signify not making a profit. That is, negative values signify loss. The points in quadrant IV represent the baseball team losing money.

Step-by-step explanation:
because of you do 5+2 = 7 then you minus 3 which you get 4.
the. if you have a production of around 10 you will get 7.
or you can do.
3+2 which is 5 and then you multiply that by 2 which is 10 and then you comprised that number therefore you will get 6 but you have to find X so we youndelie (think that's how u spell it) X which will equal to 1 and 6+1 is 7. once you get it it's quite simple
Find the average speed in km/h for a journey of 175 meters and 35 seconds
Answer:
18 km/h
Step-by-step explanation:
1. Convert 175 metres into km
1000 m = 1 km (divide by 1000)
175 ÷ 1000 = 0.175 km
so 175 m = 0.175 km
2. Convert 35 seconds into hours
60 seconds = 1 min
60 mins = 1 hour
3600 (60 × 60) seconds = 1 hour (divide by 3600)
35 ÷ 3600 = 0.00972...
3. Calculate the speed
speed = distance ÷ time
= 0.175 ÷ 0.00972...
= 18 km/h
