Answer:
8x - 7y = 56
Step-by-step explanation:
in order for lines to be parallel they need to have the same slope, the easiest way to determine if they have the same slope is to change the equations into y = mx + b form by solving for y and seeing where m=8/7
so 8x - 7y = 56
-7y = 56 - 8x
y = 56/-7 -8x/-7
y = -8 + 8/7 x
5m+6+m-18=60That's a linear equation in 'm '. There's only one number that 'm' can be
that makes the equation true. The assignment is usually to find out what
that number is.
Before we get carried away and confuse ourselves, let's do some work
on the left side, and try to make it simpler.
Do you see that ' 5m ' and that ' +m ' ? We can combine them, and write ' 6m '.
Do you see that ' +6 ' and that ' -18 ' ? We can combine those, and write ' -12 '.
Now the equation is much simpler:
6m - 12 = 60
Add 12 to each side:
6m = 72
Divide each side by 6 :
<u>m = 12 </u>
Answer:
A) x=5 or -11
Step-by-step explanation:
The given equation is:
The most suitable method so solve this quadratic equation is the square root method.
We take square root of both sides to obtain:
We now split the plus or minus sign to get;
This simplifies to:
The correct choice is A
the measure of the missing angle is 36.5
A=Adam
3A= father's age
A=15+5
so the dad is 60. I'm pretty sure.
