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.)

Answer:

Given line:

y = 3x - 1

The 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 = 5

Jenna bought a gallon of milk at the store for $3.58. About how much change did she receive from a $20 bill?​

Answers

Hi! I'm happy to help!

When Jenna bought the milk, it deducted (subtracted) $3.58 from her $20. So, let's subtract that here:

20.00

- 3.58

We have to borrow:

19.9(10)

- 3.58

10-8=2

19.9(10)

- 3.58

    .  2

9-5=4

19.9(10)

- 3.58

    .42

9-3=6

19.9(10)

- 3.58

    6.42

and 1-0=1

19.9(10)

- 3.58

$16.42

So, Jenna would receive $16.42 in change for her $20 bill.

I hope this was helpful, keep learning!

Paul bought a student discount card for the bus. The card allows him to buy daily bus passes for $1.40.
After one month, Paul bought 19 passes and spent a total of $31.60.
How much did he spend on the student discount card?

Paul spent $________
on the student discount card.

Answers

Answer:

$5

Step-by-step explanation:

First, we need to find the total amount he spent on the passes.

We just need to multiply the number of passes by the price of each pass.

19 x 1.4 = 26.6

This means he spent $26.6 on the passes.

Now, we can find out how much he spent on the discount card.

Just subtract his total spending amount by the amount he spent on passes.

31.6 - 26.6 = 5

He spent $5 on the discount card.

The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.

A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.

So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.

The domain is everything BUT those two values, because they essentially break your function.

Maths f(x) type of question please help

Answers

Since 1 < x < 5, adding each side by a, where a is negative, gives

a > ax > 5a

and adding b to each side gives

a + b > ax + b > 5a + b

or

5a + b < ax + b < a + b

Since 7 < f(x) < 23, it follows that

5a + b = 7

a + b = 23

Solve for a by eliminating b :

(5a + b) - (a + b) = 7 - 23

4a = -16

a = -4

Solve for b :

-4 + b = 23

b = 27

Solve for the value of v.

Answers

Answer:

9

Step-by-step explanation:

Since it is a straight line, therefore it will always be 180°

So...

(8v +3) +105 = 180

8v + 3 + 105 = 180

8v = 180 - 108

V = 72/8

= 9

Answer:

[tex]\boxed {\boxed {\sf v=9}}[/tex]

Step-by-step explanation:

In the diagram, there are 2 angles: 105° and (8v+3)°. They are on a straight line together, so they are supplementary angles. They must add to 180 degrees. We can set up an equation.

[tex]105 + (8v+3) = 180[/tex]

We are solving for v, so we must isolate the variable. First, we can rearrange the right side and combine the like terms (the constants without a variable).

[tex]105 +8v+3= 180 \\8v + (105+3) = 180 \\8v + 108= 180[/tex]

108 is being added to 8v. The inverse operation of addition is subtraction. Subtract 108 from both sides of the equation.

[tex]8v+108-108= 180-108 \\8v= 180-108 \\8v=72[/tex]

v is being multiplied by 8. The inverse operation of multiplication is division. Divide both sides by 8.

[tex]\frac {8v}{8}= \frac{72}{8}\\[/tex]

[tex]v= \frac{72}{8}[/tex]

[tex]v=9[/tex]

v is equal to 9.
