Evaluate -8 + 10x4 (-2).

Answer:

m=-17/4

Step-by-step explanation:

Slope is equal to m= y-y/x-x

Therefore it will be 9-(-8)/-4-0

Answer:

[tex]\boxed {\boxed {\sf m= - \frac{17}{{4}}}}[/tex]

Step-by-step explanation:

We are asked to find the slope of (0, -8) and (-4, 9). We use the following formula to calculate slope.

[tex]m= \frac{y_2-y_1}{x_2-x_1}[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the points given. We have the points (0, -8) and (-4,9). If we match the given value with the corresponding variable we see that:

Substitute the values into the formula.

[tex]m= \frac{(9)- (-8)}{ (-4) -(0)}[/tex]

Solve the numerator. Remember that 2 back to back negative signs become a positive sign.

[tex]m= \frac{17}{(-4)-(0)}}[/tex]

Solve the denominator.

[tex]m= \frac{17}{-4}[/tex]

This fraction cannot be reduced, so -17/4 is the slope.

Answer:

10

Step-by-step explanation:

let the number be n then half the number is [tex]\frac{1}{2}[/tex] n , so

[tex]\frac{1}{2}[/tex] n + 69 = 74 ( subtract 69 from both sides )

[tex]\frac{1}{2}[/tex] n = 5 ( multiply both sides by 2 to clear the fraction )

n = 10

Thus the number is 10

The expression is 24/ m-6

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Let us understand how to write expressions. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

The equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4) is y = [tex]-\frac{5}{x} x-1[/tex]

Parallel lines have the same slope. Therefore, using slope intercept form.

y = mx + b

m = slope

b = y-intercept

Therefore,

5x + 2y = 12

2y = -5x + 12

[tex]y = -\frac{5}{2} x+12[/tex]

The slope of the line is [tex]-\frac{5}{2}[/tex]

Base on parallelism, for the line that passes through (-2, 4)

y = mx + b
