In the equation x=−3y, what is the unit rate?

Mathematics
1 answer:
Paul [167]3 years ago
6 0
The unit rate is -1/3.

In direct variation, y varies directly to x by a constant ratio k.

Its equation looks like this: y = kx ; where k stands for the constant ratio.

In the above equation. x = -3y, it should be converted to the proper equation. both sides must be transferred and its accompanying sign must be changed.

3y = -x
3y/3 = -x/3
y = (-1/3)x
where: y is the total value; -1/3 is the unit rate; and x is the number of units

What is the distance, on a coordinate plane, between the points G(2.-3) and D(2, 4)?
Lady_Fox [76]

Answer:

Therefore ,the distance, on a coordinate plane, between the points G(2.-3) and D(2, 4) is GD = 7\ units

Step-by-step explanation:

Given:

point G( x₁ , y₁) ≡ ( 2 ,-3)  

point D( x₂ , y₂) ≡ (2 , 4)  

To Find:

Distance between GD=?

Solution:

Distance Formula between two point is given by

l(GD) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}

Substituting the values we get

l(GD) = \sqrt{((2-2)^{2}+(4-(-3))^{2} )}

l(GD) = \sqrt{((0)^{2}+(4+3))^{2} )}=\sqrt{49}=7\\l(GD)=7\ units

Therefore ,the distance, on a coordinate plane, between the points G(2.-3) and D(2, 4) is GD = 7\ units

PLEASE HELP WORTH 40 POINTS FOR WHOEVER ANSWERS CORRECTLY!!!! PLEASE HELP
ANTONII [103]

Answer:

x = 1 ⇔ y = -2.4

x = 2 ⇔ y = -1.8

x = 3 ⇔ y = -1.2

x = 4 ⇔ y = -0.6

Step-by-step explanation:

3x-5y=15

→ Rearrange to make y the subject

-5y=-3x+15

→ Multiply everything by -1

5y=3x-15

→ Divide everything by 5

y=0.6x-3

⇒ Substitute x = 1, 2, 3 and 4

y=0.6x-3\\ y=(0.6*1)-3\\ y=0.6-3\\ y=-2.4\\(1,-2.4)

y=0.6x-3\\ y=(0.6*2)-3\\ y=1.2-3\\ y=-1.8\\(2,-1.8)

y=0.6x-3\\ y=(0.6*3)-3\\ y=1.8-3\\ y=-1.2\\(3,-1.2)

y=0.6x-3\\ y=(0.6*4)-3\\ y=2.4-3\\ y=-0.6\\(4,-0.6)

Use a ratio box to solve this problem the ratio of new pens was 4 to 7 in all there were 242 new pens how many new pens were in
Leya [2.2K]

Complete Question

Use a ratio box to solve this problem the ratio of new pens to used pens was 4 to 7 in all there were 242 pens, how many new pens were in the box?

Answer:

88 new pens

Step-by-step explanation:

The ratio of new pens : Old pens = 4:7

Sum of Proportion = 4 + 7 = 11

Total number of pens = 242 pens

The number of new pens is calculated as:

4/11 × 242 pens

= 88 new pens

Therefore, the number of new pens = 88 new pens
