Answer:
A. –x – 6y = 42
Step-by-step explanation:
Multiply everything by 6:
6y = x + 42
The answer you are looking for is -6y+x=-42
We start by multiplying everything by 6
·6y=X+42
We then need to move X to the other side of the equation so we subtract X rom both sides.
·6Y-X=42
In order to solve the question X must be positive so we multiply everything by a quanitity of -1
·-6y+x=-42
Now this is in stardard form, so in conclusion your answer is -6y +x = -42
-I hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.
The standard form of a straight line equation is: Ax%2BBy%2BC=0
.
In your example, we would write:
x-y%2B6=0

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis.
According to the data of the statement we have the following points:
We found the slope:
Thus, the equation is of the form:
We substitute one of the points and find b:
Finally, the equation is:
Answer:
Answer:
6(7a + 9b) = 3(14a + 18b)
Step-by-step explanation:
We need to find the equivalent expression for the given expression i.e. 6(7a + 9b).
We can use the distributive property here such that,
a(b+c) = ab + ac
We have, a = 6, b = 7 and c = 9
6(7a + 9b) = 6(7a) + 6(9b)
= 42a + 54b
or taking 3 common from the above expression.
= 3(14a+18b)
Hence, the correct option is (a).
