What is the equation of the line that passes through the point (-1,4) and has a slope of -5?
Answer:
y = -5x + 4
Step-by-step explanation:
In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.
Answer:
y = -5x - 1
Step-by-step explanation:
Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.
Point slope formula = y - y = m(x - x)
m = -5 (-1, 4)
y - 4 = -5(x +1)
y - 4 = -5x - 5
y = -5x - 1
Please please help asap!!!! Solve for the indicated variable. 3a + 6b = 4 for b
Answer:
b = (4/6) - a/2
Step-by-step explanation:
6b + 3a = 4
6b = 4 - 3a
b. = (4 - 3a)/6
b. = (4/6) - a/2
The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
In the provided expression, variable and constant are there
It is given that:
The equation in a and b, where a and b are the variables:
3a + 6b = 4
Here the indicated variable is b.
To find the value of b in terms of a make the subject as b:
Subtract 3a on both the sides in the equation 3a + 6b = 4:
The equation becomes:
3a + 6b -3a = 4 - 3a
6b = 4 - 3a
Divide by 6 on both sides:
The equation becomes:
6b/6 = (4 - 3a)/6
b = (4 - 3a)/6
Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

Rebecca took a total of 12 quizzes over the course of 3 weeks. How many weeks of school will Rebecca have to attend this quarter before she will have taken a total of 24 quizzes? Assume the relationship is directly proportional.
Answer:
6 weeks
Step-by-step explanation:
If you look at the information it gives you, you can see it says 12 quizzes in 3 weeks and she needs 24 quizzes. So every 3 weeks she does 12 quizzes, and if you add 12 and 12 you get 6 weeks.
Andrew participated in a bicycle race. The total distance covered was 56
miles. If he cycled at a constant rate of 14 miles per hour, how much time
did Andrew take to complete the race?
O A) 1 hr.
B) 4 hr.
C) 7 hr.
OD 9 hr.
(B) 4 hr is the correct answer.
Explanation :★ Speed of body is defined as the ratio of distance travelled to the time taken[tex].[/tex]
speed = distance/timeGiven that,
distance = 56 miles
speed = 14 miles per hour
By substituting the values, we get
⭆ time = distance/speed
⭆ time = 56/14
⭆ time = 4 hr

Step-by-step explanation:
Sue is offered a job reshelving books in the University of Montana library from noon until 1 p.M. Each Friday. Her reservation wage for this task is $10 per hour. If the library director offers Sue $100 per hour, how much economic surplus will she enjoy as a result of accepting the job? Now suppose the library director announces that the earnings from the job will be divided equally among the 400 students who live in Sue's dormitory. Will Sue still accept? Explain how your answers to parts a and b illustrate one of the incentive problems inherent in income redistribution programs.
Answer:
Step-by-step explanation:
Sue's initial wage per hour = $10
Sue's wage per hour after the increase = $100
a. Economic surplus to be enjoyed = $100 - $10
= $90
Sue would enjoy an economic surplus of $90.
b. No, because in this case the wage per hour for each 400 student would be;
= [tex]\frac{100}{400}[/tex]
= $0.25
= 25 cents
Redistribution of income is the act of equal sharing of wealth among a certain number of people.
The problem here is that Sue would feel cheated with the division of the earnings among 400 students, but very happy when her wages was increased.
Though the income incentive redistribution programs reduce poverty, but it may be unfair.
Plz HELP with a and b I WILL MARK AS A BRAINLIEST IF YOU CAN HELP ME WITH BOTH A AND B PLZZ
Answer:
a) x = 60
b) b = 110
Step-by-step explanation:
A)
2x and 120 are vertical angles.
vertical angles are equivalent.
2x = 120
divide both sides of the equation by 2
2x/2 = 120/2
x = 120/2
x = 60
B)
b + 20 and 130 are on the same side of the line
(I forgot what the math term is, but they're also equal)
b + 20 = 130
subtract 20 from both sides of the equation
b + 20 - 20 = 130 - 20
b = 130 - 20
b = 110
2x + 9.75 - 7x= 5.15

If f(x)=2x(With an exponent of 2) -3, find f(-2)
[tex]f\left(x\right)=2x^2-3f ( x ) = 2 x 2 − 3 find f\left(-2\right)f ( − 2 ).[/tex]
Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
Answer:
f(-2) = 5
Step-by-step explanation:
We just need to substitute x with -2 and simplify.
f(x) = 2x² - 3
f(-2) = 2(-2)² - 3
f(-2) = 2(4) - 3
f(-2) = 8 - 3
f(-2) = 5

Josh practices free throws during basketball practice on Monday and Tuesday. On Monday, he attempts 15 free throws and 6 basketballs went in the basket. Over both days, Josh wants at least 80% of his balls to go in the basket. If he makes every free throw on Tuesday, what is the minimum number of free throws required on Tuesday to reach his goal?
Answer:
he has to make 12 shots
Step-by-step explanation:
Josh will have to make a minimum of 12 shots to the basket to reach his goal on Tuesday. Basically, 12 shots are 80% of 15 shots he decides to take every Monday and Tuesday.
Baskets are said to be done when the basketball ends up passing through the basket in the opponent's side of the basketball field. However, Josh is practicing his free throws here.Josh has set a goal to himself that at least 80% of his shots should be basket. Considering that he takes 15 throws on Monday the calculation of baskets will be done as below.[tex]\rm Josh's goal= \dfrac{80}{100} x 15[/tex]
So the Josh's required free throws on Tuesday will be,[tex]\rm Josh's\ goal = 12[/tex]
It can be concluded that Josh will have to make at least 12 of his 15 free throws into the basket on Tuesday to achieve his set goal of 80%.Hence, Josh will have to make 12 free throws into the basket on Tuesday to be able to score at least 80% of his free throws as baskets.

A triangular garden has two rock walls meeting at a right angle. The length of one of the walls is 20 feet. Use the image to find d, the length of the other wall.
Step-by-step explanation:
Here you go, I hope this is helpfull
The length of the other side of the wall is √500 ft
Pythagoras theorem
To get the length of 'd', we will use the pythagoras theorem as shown below:
Given the following
Hypotenuse = 30ftAdjacent = 20ftAccording to the theorem;
[tex]h^2=a^2+d^2\\30^2 = 20^2 + d^2\\900 = 400 + d^2\\d^2 = 900 - 400\\d = \sqrt{500} ft[/tex]

A) the line is not vertical
B) the line is not horizontal
C) the slope of a line is positve
D) the slope of a line is negative
Answer:
C the slope of a line is positive
Step-by-step explanation:
Hypothesis: The phrase following the "if" part of a conditional statement. So the answer would be c- The slope of a line is positive.
C) the slope of a line is positive
A conditional statement has two parts: hypothesis (if) and conclusion (then).
We have the given statement as:
If the slope of a line is positive, then the line is not horizontal.
Here, "if" part of a conditional statement is the slope of a line is positive
So, the hypothesis of the statement is the slope of a line is positive
Therefore the correct option is (C).
