Let the two numbers be x and y.
According to your question;
x + y = 7
10y + x = 10x + y + 9
By equation 1 ; x = 7-y
Substituting the value of x ;
10y + ( 7 -y) = 10(7-y) + y + 9
9y + 7 = 70 -10y + y + 9
9y + 7 = 70 - 9y + 9
=> 18y = 70 -7 + 9
=> 18y = 72
=> y = 4
Substituting for x ;
x = 7 - y
=> x = 7 -4
=> x = 3
Thus, x = 3 and y = 4;
=> The number is 34.
Answer:
Find the slope of the original line and use the point-slope formula
y−y1=m(x−x1) to find the line parallel to y=2x−7. y=2x+12
Answer:
slope intercept form
Step-by-step explanation:
The answer would be C because the middle point, which is F should be in the middle when naming the angle
Answer: m = 18
Step-by-step explanation:
m + 2m - 6 = 12 + 2m
Add m and 2m (distribute)
3m - 6 = 12 + 2m
Subtract 2m from both sides
m - 6 = 12
Add 6 to both sides
m = 18
