Mathematics

Answer:

First problem:  Answer 1

Second problem:  Answer 3

Step-by-step explanation:

Both problems are worked the same way.

First you have to find the slope of the line you are given.

Problem 1:   y = -4x + 5

Since the equation is in slope-intercept form

the slope = -4

Now look for an equation in the form y = mx + b where m = -4

That would be answer 1     y = - 4(x) + 5

Problem 2:  3x - 2y = 7

                         - 2y = - 3x + 7

                             y = 3/2(x) - 7/2

The slope = 3/2

Which equation is m = 3/2?   Answer 3:   y = 3/2(x) - 5

Answer:

-2 and -4

Step-by-step explanation:

Given the function f(x) = x² + 6x + 8

If f(x) = 0

x² + 6x + 8 = 0

Factorize

x² + 4x + 2x+ 8 = 0

x(x+4)+2(x+4) = 0

(x+2)(x+4) = 0

x+2 = 0 and x+4 = 0

x = -2 and -4

Hence the zero of the function is -2 and -4

The sum of two numbers is 50. The first number is 43 less than twice the second number.
Tomtit [17]
X, y - the numbers

The sum of the two numbers is 50.
x+y=50 \\&#10;x=50-y

The first number is 43 less than twice the second number.
x=2y-43 \\ \\&#10;50-y=2y-43 \\&#10;-y-2y=-43-50 \\&#10;-3y=-93 \\&#10;y=31 \\ \\&#10;x=50-y=50-31=19

The numbers are 19 and 31.
