Sam makes $400 per week plus $20 commission on each new cell phone plan she sells. Write an equation and solve it to determine how many new plans she sold to earn $680 last week.

(please provide steps)

Answers

the equation would be 400+20c per week so if you do that equation, to figure it out 680-400=280 and then you would divide it by 20 and whatever that answer is, in this case it would be 14.

Answer:

Option #4

Step-by-step explanation:

Expand option #4

=-3(1-2x)

=-3 -2x*-3

=-3+6x which is what your original equation was.

becoz it is a multiple choice, we can go by elimination, hence when we expand #4, we will get -3+6x

Which figure has exactly one line of symmetry? A rhombus, pentagon, rectangle and triangle are shown. A. Rhombus B. Pentagon C. Rectangle D. Triangle

Answers

Answer: The figure that has exactly one line of symmetry is B. Pentagon.

Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.

Using either method, we can see that:

A. Rhombus has two lines of symmetry: one diagonal and one vertical.

C. Rectangle has two lines of symmetry: one horizontal and one vertical.

D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.

B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.

Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.

Hope this helps, and have a great day! =)

B. Pentagon has exactly one line of symmetry

2x-8y=16
Is it linear? If so, write the equation in standard form and give the values of A,B and C.

Answers

Yes it is linear since it's in the standard form Ax+By = C

A = 2

B = -8

C = 16

Answer:

yes it's linear.

Step-by-step explanation:

you can determine if it's linear by check if you can make the equation be :

y=mx+b

so first, you can change the equation 2x-8y=16 to 8y=2x-16

and then, you can take out the common fact 2, which would be 4y=x-8

at this stage, you can even devide the whole by 4, wich the equation would be y=1/4x-2 or

     y=1/4x+(-2) which is follow the equation y=mx+c, therefore, it is linear.

I need help on a b and function 2
I dont get it

I need help on a b and function 2I dont get it

Answers

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.
