Answer:

7/8

Step-by-step explanation:

well first when you put them together like 3/8 and 7/9 you have to simplfy first. You have to cross simplify 3 and 3. Since they are the saem both turn into one. Now you mulitpy. 7 times 1 is 7 and 8 times one is 8. 7/8

Answer:

\frac{7}{24}

Step-by-step explanation:

To factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...).

The number of times that each prime divides the original integer becomes its exponent in the final result.   In our example,  Prime number 2^3=8

\frac{3*7}{2^3*3^2}

We need to perform a multiplication. The following rule is applied:

\frac{A}{B}*\frac{C}{D}=\frac{AC}{BD}

In our example, the factors in the new numerator are 3,7

The factors in the new denominator are 2^3, 3^2

What is the equation of a line that passes through the point (8, 1) and is perpendicular to the line whose equation is y=−23x+5
elena-s [515]

Answer:

y-1=\frac{1}{23} (x-8)

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation y=-23x+5. We will chose point-slope since we have a point and slope.

Point slope:y-y_1=m(x-x_1)

m\neq -23 in our new equation because it us perpendicular to it. This means we will need to change it into its negative reciprocal which is m=\frac{1}{23}.

We will substitute m=\frac{1}{23} and x_1=8\\y_1=1.

y-1=\frac{1}{23} (x-8).

This is the equation of the line perpendicular to y=-23x+5 that crosses through (8,1).
