Proportional relationship
We know a proportional relationship is when one of the variable is obtained by multiplying the other variable by a constant number.
For example, in an equation it can be represented:
<em>y = 2x</em>
<em />
In a table, we can represent it by
<em />
In a graph,
Answer: all of them
Answer:
Step-by-step explanation:
So first, lets solve for the intercepts.
Let’s start by finding the x intercept.
Plug in 0 for y.
10x+9(0)=-90
10x=-90
X=-9, so your first point on your line will be (-9,0).
Now the y intercept.
Plug in 0 for x.
10(0)+9y=-90
9y=-90
Y=-10, so your second point on your line will be (0,-10).
Use those points to create your line.

Step-by-step explanation:
The missing length is 13 because,
Lets say the top triangle is A and the bottom triangle is B.
Triangle A gives us the side GF, and Triangle B gives us the sides TU and ST. Since the triangles are similar(as stated in the problem), we can pair 2 sides GF(A) and TU(B) which is 11:22.(one way I usually figure which sides are similar is by first- matching the hypotenuse, then checking which of the remaining two is longer.. if that made any sense). You can see that their relationship is x2 or /2 (In another word, from A to B is multiplication- ex: 11 * 2 is 22, and from B to A is division- ex 22/2 is 11.) Since the missing number is the hypotenuse of triangle A and you know the Hypotenuse of triangle B all you have to do is divide side TS by 2 to get side SF. So the missing side is 13.
Answer: 13
Answer:
c = 10h
Step-by-step explanation:
c = 8h
Where,
c = Total amount she should charge a customer
h = Number of hours
8 = amount charged per hour of babysitting
A. 8 is the constant of proportionality and it means Nila charges $8 per hour of babysitting
B. If she decides to increase the rate she charges customers by $2 per hour, then the new equation she should use to determine how much to charge her customers is:
c = (8 + 2)h
c = 10h
Answer:
y = -1
Step-by-step explanation:
First, you find the slope by using the slope formula and get 0. Now, choose one coordinate and plug it into the equation y = mx + b along with the slope. If you chose the first coordinate, the equation would be -1 = (0)(5) + b. After solving for b (the y-intercept) you would get -1. Lastly, you rewrite the equation as y = -1.
