Answer:
<u>y = 10/11 x + 2.45</u>
Step-by-step explanation:
Equation of the line
First find the gradient
formula = 
= 
=
= 10/11
m is the gradient
equation of a line
y- y1 = m(x-x1)
y-7 = 10/11 (x-5)
y-7 =
- 
<u>y = 10/11 x + 2.45</u>
<u />
<em>NB i rounded of -50/11 +7 = 2.4545..... to 2.45 </em>
Answer:
first person to do what?
Step-by-step explanation:
The amount saved by Rita is $25.
Given that, the skateboard Rita wants to buy is 6 dollars less than 3 times the amount she has saved. The skateboard is 69 dollars.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the unknown number be x.
Now, 3x-6=69
⇒ 3x=75
⇒ x=75/3
⇒ x= 25
Therefore, the amount saved by Rita is $25.

Step-by-step explanation:
7*3y - 7*5 + 2*4y + 12
= 21y - 35 + 8y + 6
= 29y - 29
= 29(y-1)
Answer:
Constant of proportionality = 2
Step-by-step explanation:
F = 2b (given)
This indicates that F is directly proportional to b
That is, F ∞ b
Removing the proportionality sign, F = kb where k is the constant of proportionality.
Comparing this with F = 2b, we have that k = 2
