Step-by-step explanation:

The equation for her first job is y = 8h + 100 and the equation for her second job is y = 8.5h + 100

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Mary has two job offers.

The first job pays $8.00 an hour plus a $100 bonus.

The second job pays $8.50 an hour plus an $80 bonus.

Let h be the number of hours and y be the income.

The equation for her first job will be

y = 8h + 100

The equation for her second job will be

y = 8.5h + 100

Step-by-step explanation:

The coefficient of the variable y for the given equation 4 - 2y is -2.

A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.

We have,

An equation 4 - 2y,

So,

In the above-given expression,

We have only one variable and one Constant term,

i.e.

Constant term = 4

And,

Variable term = -2y

So,

In the variable term,

The coefficient of y = -2

So,

The coefficient of y is -2.

Hence, we can say that the coefficient of the variable y in the given equation is -2.

Answer:

The length of rectangle is 7 cm and width is 2 cm.

Step-by-step explanation:

Given that:

Area of rectangle = 14 square centimeters

The length of a rectangle is 3 centimeters less than five times its width.

Let,

L be the length and W be the width of the rectangle.

L = 5W - 3

Area of rectangle = Length * Width

14 = (5W-3)*W

[tex]14=5W^2-3W\\5W^2-3W-14=0[/tex]

Factorizing the equation;

[tex]5W^2-10W+7W-14=0\\5W(W-2)+7(W-2)=0\\(5W+7)(W-2)=0[/tex]

Either,

5W+7 = 0

5W = -7

W = -7/5

Or,

W-2 = 0

W=2

As width of rectangle cannot be negative, therefore,

Width = 2 centimeters

Length = 5(2) -3 = 10-3 = 7

Hence,

The length of rectangle is 7 cm and width is 2 cm.

Answer:

0.05606

Step-by-step explanation:

This is a binomial probability distribution problem.

84% of all households have cable TV, thus;

p = 0.84

There are six households from this area, thus; n = 6

Formula for this binomial distribution is;

P(X) = C(n, x) × p^(x) × (1 - p)^(n - x)

We want to find the proportion of groups where at most three of the households have cable TV.

Thus, it's is;

P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

P(X = 0) = C(6, 0) × 0.84^(0) × (1 - 0.84)^(6 - 0) = 0.00001678

P(X = 1) = C(6, 1) × 0.84^(1) × (1 - 0.84)^(6 - 1) = 0.000528

P(X = 2) = C(6, 2) × 0.84^(2) × (1 - 0.84)^(6 - 2) = 0.006963

P(X = 3) = C(6, 3) × 0.84^(3) × (1 - 0.84)^(6 - 3) = 0.04855

Thus;

P(X ≤ 3) = 0.00001678 + 0.000528 + 0.006963 + 0.04855 = 0.05606

Answer:

the better buy is that from the second store as it is cheaper than that purchased from the first store

Step-by-step explanation:

Given that :

First store :

Amount paid = $12.16

Pounds of shrimps = 4.07

Unit price :

Amount paid / pounds of shrimps

$12.16 / 4.07 = $2.9877

= $2.99 = 299 cents

second store :

Amount paid = $14.99

Pounds of shrimps = 5.11

Unit price :

Amount paid / pounds of shrimps

$14.99 / 5.11 = $2.933

= 2.93 = 293 cents

Hence, the better buy is that from the second store as it is cheaper than that purchased from the first store

Answer:

36miles

Step-by-step explanation:

Given parameters:

Rate  = 12mph

Time  = 3hr

Unknown:

Distance = ?

Solution:

The given rate amount is the speed. Speed is the distance divided by the time.

It is mathematically expressed as:

         Speed  = [tex]\frac{distance}{time}[/tex]  

    Distance  = Speed x time

    Distance  = 12 x 3  = 36miles

Answer:

Step-by-step explanation:

Answer:

y -y1 = m(x-x1)  (this is point slope form)

find the slope using the equation (y2-y1)/(x2-x1) (plug in the points)

(-4,5) is point 1 and (-6,3) is point 2

(3-5)/(-6-(-4))

-2/ -2

1 (this is the slope)

and then plug in all the things you know

y - 5 = 1 ( x - ( -4))

C) Reflection across the x-axis.

Step-by-step explanation:

From Linear Algebra we define the reflection across the x-axis is for [tex]P(x,y) =(x,y)[/tex]:

[tex]P'(x,y) = (x, -y)[/tex] (1)

If we know that [tex]A(x,y) = (-1, 2)[/tex], [tex]B(x,y) =(-1,5)[/tex], [tex]C(x,y) = (-3, 5)[/tex] and [tex]D(x,y) =(-3, 2)[/tex], then the reflected points are, respectively:

[tex]A'(x,y) = (-1, -2)[/tex]

[tex]B'(x,y) = (-1,-5)[/tex]

[tex]C'(x,y) = (-3,-5)[/tex]

[tex]D'(x,y) = (-3,-2)[/tex]

In consequence, Kim performed a reflection across the x-axis to create triangle A'B'C'D'. The correct answer is C.

This question is based on the reflection of x- axis. Hence the correct answer is C, reflection across the x-axis.

Given:

Transform  rectangle ABCD to rectangle A'B'C'D',

The vertices of rectangle ABCD is A(-1,2) B(-1,5) C(-3,5) D(-3,2).

The vertices of rectangle A'B'C'D is A'(-1,-2) B'(-1,-5) C'(-3,-5) D'(-3,-2).

We need to determined the transformation that Kim perform to create rectangle A'B'C'D.

From Linear Algebra we define the reflection across the x-axis is for,

P(x,y) = (x,y)

P(x,y) = (x,-y)                                .....(1)

It is given that  A(-1,2), B(-1,5), C(-3,5) and D(-3,2).

Therefore from equation (1)  above point becomes,

A'(x,y) = (-1,-2)

B'(x,y) =(-1,-5)

C'(x,y) =(-3,-5)

D'(x,y) =(-3,-2)

Therefore, It is observe that Kim performed a reflection across the x-axis to create triangle A'B'C'D'. Hence the correct answer is C, reflection across the x-axis.

Answer:

The sale price of the item is  $ 255

Step-by-step explanation:

To determine the amount of discount ( d ) offered by the store, we calculate  

15 %  of the sale price. Thus:

d =  300  ×  15 ÷ 100

d  =  3 00  ×  15  ÷ 1 00  (take the 2 zeros out on both the hundred and 3 hundred)

d  =  3  ×  15

d  =  45

If the amount of discount is known, the sale price ( s ) of the item will be the regular price minus the discount. Hence:

s  =  300  −  45

s  =  255
