Answer:
-1 = -5
0 = -1
2 = 5
Step-by-step explanation:
In order to do this you need to follow these five (5) steps:
1) Know what each of the variables mean in an equation of a line. The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness of a line and the y-intercept is the point where the line intersects the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)
2) Identify the m (slope) and the b (y-intercept). The slope is 3, which can also be written as 3/1. The y-intercept is -1. (Remember that subtraction of 1 is the SAME thing as adding -1!) Since the y-intercept is a point it will be plotted at (0, -1).
3) Plot the y-intercept first. Start at the origin (intersection of the x- and y-axes) since the x coordinate is 0. Then move DOWN 1 unit since the y-coordinate is negative.
4) Use the m (slope) to plot at least three new points. The slope can also be represented as "rise/run" or the amount of units that you move UP or DOWN (vertically), then LEFT or RIGHT (horizontally). (Remember: if the numerator is positive (move UP); numerator is negative (move DOWN); denominator is POSITIVE (move RIGHT); denominator is NEGATIVE (move LEFT)). Since our slope is 3/1, and both the numerator and denominator are POSITIVE, that means we will be "rising" (moving UP) 3 units and "running" (moving RIGHT) 1 unit.
Start at the y-intercept of (0, -1) and move up 3 units and to the right 1 unit. You should be at (1, 2). Plot a point here. Then do it again. You should now be at (2, 5). Plot another point. Now, do it one more time. You should now be at (3, 8). Plot your last point. (If you wish to continue plotting additional points, feel free to do so.)

Given line:
y = 3x - 1The table has x-values and asks to find f(x) for each x.
f(x) is same as y, plug in x- values to get f(x):
x = - 1 ⇒ f(-1) = 3(-1) - 1 = -3 - 1 = - 4x = 0 ⇒ f(0) = 3(0) - 1 = 0 - 1 = - 1x = 2 ⇒ f(2) = 3(2) - 1 = 6 - 1 = 5Related Questions
Nolan and his children went into a grocery store and he bought $8 worth of apples
and bananas. Each apple costs $2 and each banana costs $0.40. He bought 5 times as
many bananas as apples. By following the steps below, determine the number of
apples, 2, and the number of bananas, y, that Nolan bought.
Answers
To solve this problem form the system of equations first, then solve them to find the values of the variables.
Nolan bought 2 apples and 10 bananas.
It's given that,
Nolan and his children bought fruits (Apples and bananas) worth $8.Cost of each apple and bananas are $2 and $0.40 respectively.Let the number of bananas he bought = y
And the number of apples = x
Therefore, cost of the apples =$2x
And the cost of bananas = $0.40y
Total cost of 'x' apples and 'y' bananas = $(2x + 0.40y)
Equation representing the total cost of fruits will be,
(2x + 0.40y) = 8
10(2x + 0.40y) = 10(8)
20x + 4y = 80
5x + y = 20 --------(1)
If he bought 5 times as many bananas as apples,
y = 5x ------(2)
Substitute the value of y from equation (2) to equation (1),
5x + 5x = 20
10x = 20
x = 2
Substitute the value of 'x' in equation (2)
y = 5(2)
y = 10
Therefore, Nolan bought 2 apples and 10 bananas.

If a floor is 9 feet, how many 6 square inch tiles do you need?
Answers
Answer:
A floor 9 feet by 12 feet, is to be tiled with 4-inch-by-6-inch tiles.
Step-by-step explanation:
How many tiles are needed to cover the floor?
9 ft is 9 x 12 = 108 in
12 ft is 12 x 12 = 144 in.
The area of the floor is 108 in x 144 in = 15,552 sq. in.
Each tile is 4 in x 6 in = 24 sq. in.
Dividing 15,542 sq. in by 24 sq. in gives an answer of 648 tiles.

If a distribution is skewed to the right with no outliers, which expression is correct?
mean < median
mean ≈ median
mean = median
mean > median
We can’t tell without examining the data.
Answers
Answer:
Mean>Median
Step-by-step explanation:
A right skewed distribution with no outliers will have it's mean value greater than the median ( mean > median)
A distribution is said to be right skewed if it's peak is to the left such that it has a long tail to the right.
Conversely, a distribution with it's peak to the right such that it has a long tail is said to be left skewed.
Using the analogy of a boxplot, a right skewed distribution will have it's box to the left and a longer whisker to the right. This means that the median point which is the vertical line in between the box will be lesser than the mean value.
Median < mean = mean > median

A number increased by 10 is 32. How would I write that as an equation?
Answers
Answer:
4.
Step-by-step explanation:
Remember that “of” means multiplication, so from your question we infer the following equation:
(1/2)x + 10 = 12
First, subtract 10 from both sides:
(1/2)x = 2
Multiply both sides by 2 to eliminate the fraction:
x = 4
Now substitute for x in the original equation to prove this:
(1/2)x + 10 = 12
x = 4
(1/2)4 + 10 = 12
4/2 + 10 = 12
2 + 10 = 12
12 = 12
So the number, x, is 4.
it is an example of your question.

Answers
Answer:
To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you'll use that value to solve for y (or x if your parabola opens to the side) by using the quadratic equation. Those two coordinates are your parabola's vertex.
