We can simply add the expression to simplify the expression. So,

(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.

=(7-8)+(3i+9i) Group the like terms.

= -1 + 12i

Answer:

The equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}

Step-by-step explanation:

We need to find the equation of line, having slope m = -4 and passes through point (-2,-9)

First we need to find slope and y-intercept of the line.

The slope is given i.e. m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, y-intercept can be found using:

y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

y=mx+b\\y=-4x-17

Now writing in form of Ax + By = C

y=-4x-17\\4x+y=-17

So, the equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}.

Answer:

The GCF is going to be 20

Step-by-step explanation:

This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here

The prime factorization of 20, 2 × 2 × 5= 20

The prime factorization of 80, 2 × 2 × 2 × 2 × 5 = 80

The common factors are 2, 2, and 5. We multiply those to get the GCF.

2 × 2 × 5 = 20
