Answer:
y = 66x + 340
Step-by-step explanation:
The question asks to give the slope-intercept equation of a line with the slope given and it passes through a given line.
Generally, the equation of a line is given by:
y = mx + c, where m is the slope and c is the intercept. We have the slope given but we do not have the intercept. Hence, the first thing we do is to find the value of the intercept. We calculate that as follows:
since the line passes through a point, we substitute the values of the ordinate and the abscissa in the general equation of the line.
This means; 10 = 66(-5) + C
C = 10 + 330 = 340
Hence, the general equation of the line is;
y = 66x + 340
Answer:
Yes it is

Answer:
45%
Step-by-step explanation:
The formula to work out the decrease is:
Percentage Decrease= actual decrease / original amount X 100%
1) So firstly, we have to work out the decrease, to do this we have to do is do $750-$412.50= $337.50
2) We can now substitute this into our formula which will now be. (We will also add the original amount, which is $750.00)
Percentage Decrease= 337.50 / 750.00 X 100% = 45
The percentage decrease is 45%
Answer:
45
Step-by-step explanation:
35%=0.35
0.35x=17.5
x=17.5/0.35=50
90%=0.9
0.9*50=45
