Remember PEMDAS.
Parenthesis
Exponent
Multiplication/Division
Addition/Subtraction
First you see if there is anything that needs to be solved in perentheses. Insidently there is not. The only thing that is in perentheses is an integer and not an equation. Then you see if there is any exponents, yet again there is not. Next you find any Multiplication or Division. These go together and are solved from left to right in this equation there is a multiplication. Finally you solve the additon and subtraction together. There is an instance of this as well. Here is how to work it out.
(-2) + 9 * 10
= (-2) + 90
= 90 - 2
= 88
((-2) + 90 is the same thing as 90 - 2 so you can write it that way if it is easier for you)

Hope this helps!!!

Parentheses, Exponent, Multiply, Division, Addition, Subtraction is your order (aka PEMDAS). Multiply 9x10 which gives you 90, then add -2 (or subtract 2) and your answer is 88.

A line passes through point A (14,21). A second point on the line has an x-value that is 125% of the x-value of point A and a y-

seropon [69]

Answer:

The equation of the line in point-slope form is $y-21 = - \frac{3}{2}\cdot (x-14)$ .

Step-by-step explanation:

According to the statement, let $A(x,y) = (14,21)$ and $B(x,y) = (1.25\cdot x_{A},0.75\cdot y_{A})$ . The equation of the line in point-slope form is defined by the following formula:
