Answer:

1 or 9.

Step-by-step explanation:

A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".

So, in this case, the coefficient of 9x would be 9.

The coefficient of x^2 would be 1.

Hope this helps!

What is the measure of angel A rounded to nearest whole number ?
snow_lady [41]
Use inverse cosine here because you have the side adjacent to angle A and the hypotenuse.  On your calculator, press the 2nd key then cosine to see this on your display cos^{-1} then enter 8/17 to give you an angle measure of 62 degrees.

What is a equation of the line that passes through the point (−5,7) and is parallel to the line x+5y=10
dsp73

Answer:

\displaystyle y = -\frac{1}{5} x +6

Step-by-step explanation:

<u>Equation of a LIne</u>

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.

This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.

Two parallel lines have equal values for the slopes. The equation of the line

x + 5y = 10

Can be rearranged in such a way we can find its slope. Let's solve it for y:

5y = -x + 10

y = -\frac{1}{5}+2

The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:

\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )

Adding 7:

\displaystyle y = -\frac{1}{5} ( x + 5 )+7

Operating:

\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7

\displaystyle y = -\frac{1}{5} x -1+7

\boxed{\displaystyle y = -\frac{1}{5} x +6}
