Answer:

y=2/3x+4

Step-by-step explanation:

to find x, count the rise over run between two points. to find your b value, find where the line crosses the y axis

Answer:

(1, 3)

(2, 6)

(4, 12)

(6, 18)

Step-by-step explanation:

Time represents s, or the x value when plotting (x, y) and distance represent m or the y value when plotting.

For the first one, plot it at (1, 3), so look where time is, the horizontal line, and find one. Then from there, go up three places. That is where you will plot your first point.

The second one will be plotted at (2, 6). Find two on the horizontal line, and then go up six spaces. That is where you will plot your second.

Do the same thing for the last two. You should plot your points at:

(1, 3)

(2, 6)

(4, 12)

(6, 18)

Answer:

  -1/2

Step-by-step explanation:

The constant in the equation is the value that y has when x=0, because the x-term evaluates to zero when x=0. The constant term in this equation is -1/2, so that is the y-value when x=0.

  (x, y) = (0, -1/2) . . . . where the graph crosses the y-axis

Answer:

The cost after discount would be $15.40

Step-by-step explanation:

Given that:

Discount card = 12%

Cost of items bought = $17.50

Amount of discount = 12% of 17.50

Amount of discount = [tex]\frac{12}{100}*17.50[/tex]

Amount of discount = 0.12 * 17.50

Amount of discount = $2.10

Cost after discount = 17.50 - 2.10

Cost after discount = $15.40

Hence,

The cost after discount would be $15.40

Answer:

  (b)  (6, 0)

Step-by-step explanation:

You are given the value of x. Substitute that in the other equation and find the value of y.

  -3x +14y = -18

We know x=6 from the second given equation, so ...

  -3(6) +14y = -18

Add 18 to both sides

  14y = 0

Divide by 14

  y = 0

Then the solution is ...

  (x, y) = (6, 0)

Answer:

25 chairs

Step-by-step explanation:

If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?

The percent gain = 60%

Number of chairs to be sold = x

Hence:

40 chairs = 10,000

60/100= 40 - x/x × 100

0.6= 40 - x/x

Cross Multiply

0.6x = 40 - x

0.6x + x = 40

1.6x = 40

x = 40/1.6

x = 25 chairs

The graph represents the inequality y < 1.

Option B is the correct answer.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The horizontal line through the point (4, 1).

This horizontal line passes through y = 1.

The region below this horizontal line will be y < 1.

Thus,

The graph represents y < 1.

Answer:

Step-by-step explanation:

Multiply the first equation by 4,and multiply the second equation by 1.

4(x−3y=−6)

1(−4x+9y=9)

Becomes:

4x−12y=−24

−4x+9y=9

Add these equations to eliminate x:

−3y=−15

Then solve−3y=−15for y:

−3y=−15 (Divide both sides by -3)

y=5

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

x−3y=−6

Substitute5foryinx−3y=−6:

x−(3)(5)=−6

x−15=−6(Simplify both sides of the equation)

x−15+15=−6+15(Add 15 to both sides)

x=9

Answer:

1. 1 in 5

2. There are 5 colors it could land on, and orange is one of them.

3. 40 different combinations

4. There are 5 colors with 8 corresponding numbers. 5x8=40

Step-by-step explanation:

1) 20%

2) Assuming that on the spinner with color, every section has an equal share, then the probability of landing on orange is [tex]\frac{1}{5}[/tex] or 20%. This is because, the orange section is one of the five equal sections, or [tex]\frac{1}{5}[/tex] or the spinner. [tex]\frac{1}{5}[/tex] in decimal form is 0.2, to convert to a percent, multiply by 100. Hence one gets, 20%.

3) 40

4) There are 5 sections on the spinner with color, hence 5 possible outcomes when one spins the spinner. On the black and white spinner, there are 8 sections, hence 8 possible outcomes when one spins the spinner. To find the total number of outcomes resulting from the two events, one must multiply the total outcomes from one event by the total outcome of the other event. When one does this, they get that there are 40 possible events.
