Which of the following best compares the slopes and y-intercepts of the two functions? (1 point)
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.

Solve the simultaneous equations 2x + y = 5 and 2y = x – 10.

The given equations are :
[tex]2x + y = 5[/tex][tex]2y = x - 10[/tex]From the first equation, we get :
[tex]2x + y = 5[/tex][tex]y = 5 - 2x[/tex]now, let's put the value of y as (5 - 2x) in second equation to find the value of x :
[tex]2y = x - 10[/tex][tex]2(5 - 2x) = x - 10[/tex][tex]10 - 4x = x - 10[/tex][tex]5x = 20[/tex][tex]x = 4[/tex]hence, value of x = 4, Plugging the value of x in second equation :
[tex]2y = x - 10[/tex][tex]2y = 4 - 10[/tex][tex]2y = - 6[/tex][tex]y = - 3[/tex]so, the required values are :
x = 4 y = -3
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.

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

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

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.

Ann is helping her aunt sew a lace border onto 2 quilts. Each quilt is 60 inches wide by 80 inches long. At the craft store, they buy a 25-yard roll of lace. How many inches of lace will they have left after finishing the quilts?
Answer:
340 inches
Step-by-step explanation:
25 yds = 900 in
60 + 80 + 60 + 80 = 280
280 x 2 = 560
900 - 560 = 340

If (x+2,5)=(3y+2)find x and y
Answer:
X = 7
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

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.

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)
