4.2 Weekend Earnings (Will get brainlyest ¡ please respond)
Jada has time on the weekends to earn some money. A local bookstore is looking for someone to help sort books and will pay $12.20 an hour. To get to and from the bookstore on a work day, however, Jada would have to spend $7.15 on bus fare.
Write an equation that represents Jada’s take-home earnings in dollars, if she works at the bookstore for hours in one day.

Answer:

Step-by-step explanation:

3x =15-5y

Add 5y and subtract 3x on both sides

5y=15-3x

y=(15-3x)/5

Answer:

m= -38

Step-by-step explanation:

-(6m+8)=4(17-m)

-6m-8=68-4m

-6m+4m-8=68

-2m-8+8=68+8

-2m=76

-2m/-2=76/-2

m= -38

Answer:

x = 69

Step-by-step explanation:

x+x+(x-27) = 180

3x = 207

x = 69

Answer:

The length of side BD is 4.62 units to the nearest hundredth

Step-by-step explanation:

In Δ ABC

∵ m∠ABC = 90°

∵ BD ⊥ AC

∴ AB × BC = BD × AC

∵ AB = 12 units

∵ BC = 5 units

∵ AC = 13 units

→ Substitute them in the equation above

∴ 12 × 5 = BD × 13

∴ 60 = 13 BD

→ Divide both sides by 13 to find BD

∴ 4.615384615 = BD

→ Round it to the nearest hundredth

∴ BD = 4.62 units

∴ The length of side BD is 4.62 units to the nearest hundredth

Step-by-step explanation:

12*11=132

36*29=1044

84*27=2268

Answer:

its asking you what the slope of the line is (rise/run) and for the point at which the line crosses the y axis (verticle line)

Step-by-step explanation:

When finding the slope you count the number of units up and the number of units across. This would be -1/1 or -1 because the graph shows a scale of 100, and the slope is going down 100, and across 100. this makes the slope negative since it's going downwards. so the slope would be -100/100 which would simplify to -1.

the y-intercept is where the line crosses the y axis. if this point is below the x-axis, then the y-intercept would be negative. in this problem however, the line crosses the y-axis at the origin (0,0)

so your equation would be y=1x+0, but simplified it would be y=x (the one isnt used because there is a single x value and the +0 is gone because it holds no value)

Answer: x = 2

Simplify and Distribute

(−5)(4x)+(−5)(−2)=(−2)(3)+(−2)(6x)

−20x+10=−6+−12x

−20x+10=−12x−6

Adding 12x both sides.

−20x+10+12x=−12x−6+12x

−8x+10=−6

Subtract 10 both sides

−8x+10−10=−6−10

-8x = -16

Then divide both sides by 8

-8x/8 = -16/8

Answer:

Smallno. =16

Bug no. =36

Step-by-step explanation:

Y=big number

X=small number

X+Y=52

Y=2X+4

Substitute

X+2X+4=52

3X=48

X=16(small no.)

Y=36(large no.)

Checking:

36+16=52(yay correct)

36=(2*16)+4 (coorrectoo!)

Answer:

Step-by-step explanation:

on my test

Variance is the measurement of the spread between numbers in a given set of data.

The variance for the set is 12083.929

It is the measurement of the spread between numbers in a given set of data.

We have,

3, 33, 303, 233, 3, 73, 83, 63

The formula to find variance:

Find the means of the set of data.

Find the deviation of the set of data from the mean.

Find the sum of the squares of the mean deviations.

Divide the sum of the squares of the mean deviations by (n-1)

where n is the number of data in the set.

The mean:

= (3 + 33 + 303 + 233 + 3 + 73 + 83 + 63) / 8

= 794/8

= 99.25

Deviation from the mean:

3 - 99.25 = -96.25

33 - 99.25 = -66.25

303 - 99.25 = 203.75

3 - 99.24 = -96.25

73 - 99.25 = -26.25

83 - 99.25 = -16.25

63 - 99.25 = -36.25

The sum of the squares of Mean deviation:

= 9264 + 4389 + 41514 + 9264 + 689 + 264 + 1314

= 84587.5

The variance:

= 84587.5 ÷ (8 - 1)

= 84587.5 / 7
= 12083.929

Thus,

The variance for the set is 12083.929

Answer:

you find slope from a table by taking any two points. the left side is the input of the table, the x, and the right side is the output the y. whenever you're finding the points to do slope, they must be correlated.

__x__|__y__

___2_|__4___

__3__|___6__

so if you want to choose 2 for the x input then you must choose the 4 as the y output.

After choosing the two points, (2,4) and (3,6), you need to find the slope which is y-y/x-x. so in this case it's 6-4/3-2. after subtracting you get, 2/1 which if you simplify, it's 2. Or you divide which is also 2. I hope this helped.

Answer:

y = 3x - 5

Step-by-step explanation:

Let the equation be y = mx + c

Since the equation is parallel to y = 3x + 6, gradients of the two eqns are the same

therefore, m = 3

sub (4, 7):

7 = 3(4) + c

c = -5

therefore, equation of the line is y = 3x - 5

The transformations of g(x) = |- 2x + 6| in relation to the parent function will be Translated right 3 units and Vertical Stretch. Then the correct option is A and E.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The absolute function is given as,

y = |-2x + 6|

Simplify the equation, then we have

y = |-2x + 6|

y = 2|x - 3|

The transformations of g(x) = |- 2x + 6| in relation to the parent function will be Translated right 3 units and Vertical Stretch. Then the correct option is A and E.
