What are the points for y=-3x+4 and how do I graph it

Mathematics

mestny [16]4 years ago
6 0

Answer:

(-3,13) (-2,10) (-1,7) (0,4) (1,1) (2,-2) (3,5) (4,8)  are your graph points.

Step-by-step explanation:

Okay so to find the points, you have to create a table graph with a set of x values.

in this case, your equation y=-3x+4 the x can be replace with a set of numbers and these will be your plots.

-3(-3)+4= 13

-3(-2)+4= 10

-3(-1)+4= 7

-3(0)+4= 4

-3(1)+4= 1

-3(2)+4= -2

-3(3)+4= -5

-3(4)+4= -8

Naturally with these points a shape will form ideally a straight line. Hopefully this helps and good luck!

After 4 days, a plant is measured to be 10 inches tall. Later, after a total of 20 days, then height is measured to be 18 inches
vesna_86 [32]

Given :

After 4 days, a plant is measured to be 10 inches tall.

Later, after a total of 20 days, then height is measured to be 18 inches.

To Find :

The rate of growth for the plant.

Solution :

We know, rate is given by :

Rat e=\dfrac{\text{Change in height}}{\text{Time taken}}\\\\Rate = \dfrac{18-10}{20-4}\\\\Rate = 0.5 \ inch/day

Therefore, rate of increase of height is 0.5 inch/day .

Hence, this is the required solution.

The ratio of the angle measures in a quadrilateral is : : : . What is the measure of each angle?
Ganezh [65]

Answer:

  60° : 75° : 120° : 105°

Step-by-step explanation:

I like to work these by considering the relationship between a "ratio unit" and the angle it represents. Here, the sum of ratio units is 4+5+8+7 = 24. The sum of angles in a quadrilateral is 360°, so each ratio unit must stand for ...

  360°/24 = 15°

Multiplying the ratio units by this value, we find the angles to be ...

  (4 : 5 : 8 : 7) × 15° = 60° : 75° : 120° : 105°

The cost to ride a ferris wheel is $2.00 per person. The ferris a wheel has a capacity of
irakobra [83]

Answer:

When we have a function f(x), the domain of the function is the set of all the inputs that "work" (Not only in a mathematical way, the context is also important) with the function f(x)

In this case, we have a function M(p) = $2*p

This function represents the amount of money collected depending on the number of people who ride on the ferris whell.

Then p can be only a whole number (we can not have 1.5 people, only whole numbers of people).

And we also know that the maximum capacity of the ferris is 64 people.

Then:

p ≤ 64

And we also should add the restriction:

0 ≤ p ≤ 64

(Because p can't be smaller than zero)

Such that p should also be an integer, then, the domain is:

D: p ∈ Z, p ∈ {0, 1, 2, ..., 64}
