Joanne earned $57 in tips yesterday. Her earnings were $13 less than 7/8 of Erin's earnings.

1. Write an equation to represent Erin's earnings, x.

2. How much did Erin earn in tips?

Answers

9514 1404 393

Answer:

57 = (7/8)x -13$80

Step-by-step explanation:

1. I find it convenient to use variable names that remind me what they stand for. Here, we can use "j" to represent Joanne's earnings, and "e" to represent Erin's earnings.

  j = 57 . . . . . Joanne earned $57

  j = (7/8)e -13 . . . . . Joanne's earnings were $13 less than 7/8 of Erin's

Substituting for j, we get one equation for Erin's earnings

  57 = (7/8)e -13

Using 'x' for Erin's earnings, this is ...

  57 = (7/8)x -13

__

2. We can solve the equation as follows:

  70 = 7/8x . . . . . . add 13

  80 = x . . . . . . . . . multiply by 8/7

Erin earned $80 in tips.

Answer:

Step-by-step explanation:

57 = ⅞x - 13

x= 70(8/7) = $80

evaluate the function when x = 0

What is the slope and y-intercept of y-6x=4?

Answers

Answer:

Slope: -6 Y-intercept: -4

Step-by-step explanation:

You have to put the 4 on the same side as the expression so that y-6x-4=0 so the -6x is the slope and the -4 is the y-int because of y=mx+b

rate of change y=5x+10

Answers

Answer:

5

Step-by-step explanation:

The equation [tex]y=5x+10[/tex] is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format [tex]y=mx+b[/tex], such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,

[tex]y = mx + b\\\\m=slope\\b = y-intercept.[/tex]

The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation [tex]y=5x+10[/tex] is given in the slope-intercept form, and the coefficient ([tex]m[/tex]) equals ([tex]5[/tex]), therefore the slope is ([tex]5[/tex]).

Find the area of a sector with a central angle of 7.2 radians and a radius of 14 units

Please include steps

Answers

Answer:

[tex]\boxed {\boxed {\sf a= 705.6 \ units^2 }}[/tex]

Step-by-step explanation:

Since we are given the central angle in radians, we should use this formula for the sector area:

[tex]a=\frac{1}{2}r^2 \theta[/tex]

where r is the radius and θ is the angle in radians.

The radius is 14 units and the angle is 7.2 radians.

[tex]r= 14 \ units \\\theta= 7.2[/tex]

Substitute the values into the formula.

[tex]a= \frac{1}{2} (14 \ units)^2 (7.2)[/tex]

Solve the exponent.

(14 units)²= 14 units* 14 units =196 units²

[tex]a=\frac{ 1}{2} (196 \ units^2)(7.2)[/tex]

[tex]a=\frac{ 1}{2}(1411.2 \ units^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]a= 705.6 \ units^2[/tex]

The area of the sector is 705.6 square units.
