Answer:

x by 1 times 15 to the third power

Step-by-step explanation:

Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?

Answers

The value of x is -1 and value of y is -1.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equations are

x+5y=-6...(1)

5x – 3y = -2...(2)

Multiply equation 1 with 5

5x+25y=-30..(3)

Subtract equation 2 and equation 3

5x-3y-5x-25y=-2+30

-28y=28

Divide both sides by 28

y=-1

Now plug in y value in equation 1

x=5-6

x=-1

Hence, the value of x is -1 and value of y is -1.

Answer:

16

Step-by-step explanation:

Recall that the product of a negative number and another negative number is a positive number.  Thus, -(-5) = +5, and the original expression becomes

6.9 + 5 + 4.1​.

Combining the mixed numbers 6.9 and 4.1, we get 11.

Combining 11 and 5 results in 16.

(c) Paul uses the function y = 7x + 30 to model the situation. What score does Paul’s model predict for 3 hours of homework?

(d) Describe what the number 30 in Part (c) mean in the context of the situation?

Answers

Answer:

(c) Paul's model predicts a score of 51 for 3 hours

(d) 30 represents the y intercept

Step-by-step explanation:

Given

[tex]y = 7x + 30[/tex]

Solving (c): What is y when x is 3

Substitute 3 for x in [tex]y = 7x + 30[/tex]

[tex]y = 7*3 + 30[/tex]

[tex]y = 21 + 30[/tex]

[tex]y = 51[/tex]

Solving (d): What does 30 represent

An equation is represented as:

[tex]y = mx + b[/tex]

Where

[tex]b = y\ intercept[/tex]

Compare: [tex]y = mx + b[/tex] to [tex]y = 7x + 30[/tex]

[tex]b = 30[/tex]

This implies that 30 represents the y intercept

Which equation in point-slope form describes the line that passes through the point (4,-5) and is perpendicular to
the line represented by
- 7x + 2y = 14?

Answers

9514 1404 393

Answer:

  D  y +5 = -2/7(x -4)

Step-by-step explanation:

The point-slope form is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

You're given (h, k) = (4, -5), so the equation will be of the form ...

  y +5 = m(x -4) . . . . for some slope m

This form eliminates the first two choices.

__

The slope of the given line is the coefficient of x when solved for y:

  2y = 7x +14

  y = 7/2x +7  . . . .  slope is 7/2

The perpendicular line will have a slope that is the opposite reciprocal of this, ...

  -2/7 . . . . slope of perpendicular line

This is the slope shown in choice D:

  y +5 = -2/7(x -4)
