Can someone please answer this I have the same qs
Answer:
7x - y = 5
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in point- slope form and rearrange into standard form.
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 7 and (a, b) = (1, 2)
y - 2 = 7(x - 1) ← in point- slope form
y - 2 = 7x - 7 ( subtract y from both sides )
- 2 = 7x - y - 7 ( add 7 to both sides )
5 = 7x - y , that is
7x - y = 5 ← in standard form
A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.
Answer:
x= 11
Step-by-step explanation:
or, 9x-18=81
or, 9x=81+18
or, 9x=99
or, x=99/9
or, x=11
