Answer:

a =13/5

Step-by-step explanation:

f(x) = 6x − 5

f(5a) = 6*5a − 5=73

30a -5 = 73

Add 5 to each side

30a -5+5 = 73+5

30a =78

Divide by 30

30a/30 = 78/30

a =13/5

write the equation of a parallel to the given line and passing through the given point. y=-x+7; (7,1) I need the answer now plea

leva [86]

Parallel lines have the same slope. Since our reference line has a slope of -1, so will a line parallel to it. Thus far we have:

y=-x+b, using point (7,1) we can solve for b

1=-7+b

8=b so the parallel line passing through (7,1) is:

y=-x+8

The greatest common factor of 3m2n + 12mn2 is

Kamila [148]

$3m^2n+12mn^2$
In both the sets, 3 and m as well as n can be found as common factors.
So,
3mn( m+4n)

Therefore the answer is 3mn (#3)

1Ellen says that 1 2/5 equals 5 ÷7 Is she<br>correct? Explain.

Anastasy [175]

No she is not because 1 2/5 is a bigger number than 5/7.

1 2/5 in decimal form is 1.4, and 5/7 in decimal form is .714.
