Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 4/5. In other words, a change of 1 unit in x corresponds to change of 4/5 units in y. Graph the line and write the equation of the line.

Answer:

(2, 4)

Step-by-step explanation:

Since, lines are intersecting at point (2, 4).

Therefore, (2, 4) is the solution.

Answer:

1.74%

Step-by-step explanation:

2.87-2.82=0.05

0.05/2.87=x/100

0.05x=287

x=1.74

Answer:

c. f(n) = (n+1)^2 + 2

Step-by-step explanation:

It is c. because...

f(n) = (1+1)^2 + 2

        2^2 + 2

        4 + 2 = 6 (first term)

f(n) = (2+1)^2 + 2

        3^2 + 2

        9 + 2 = 11 (second term)

f(n) = (3+1)^2 + 2

        4^2 + 2

        16 + 2 = 18 (third term)

Answer:

$2250

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2.75%/100 = 0.0275 per year,

then, solving our equation

I = 2250 × 0.0275 × 8 = 495

I = $ 495.00

The simple interest accumulated

on a principal of $ 2,250.00

at a rate of 2.75% per year

for 8 years is $ 495.00.

Answer:

20 : 65

Step-by-step explanation:

2 x 4 = 6

7 x 4 = 28

2 x 7 = 14

7 x 7 = 49

2 x 11 = 22

7 x 11 = 77

2 x 10 = 20

7 x 10 = 70 not 65

Answer:

C - 20:65

Step-by-step explanation:

7 can't even divide into 65.

Answer:

P = k*q*r

Step-by-step explanation:

P = kqr

7 = k*2*1.5

7 = 3k

k = 7/3

b. P = kqr

= 7/3*4*6

= (7*4*6)/3

= 168/3

= 56

P = 56

c. P = kqr

1 = 7/3*q*3

1 = (7*q*3)/3

1 = 21q/3

Cross product

1*3 = 21q

3 = 21q

q = 3/21

= 1/7

q = 1/7

d. P = kqr

5 = 7/3*8*r

5 = (7*8*r)/3

5*3 = 56r

15 = 56r

r = 15/56

Answer (numbers needed in boxes, going from top to bottom):

1

-1

-3

3

Step-by-step explanation:

f(x) is another way of saying y. So, the table is asking, "when substituting these x values for the x's in the function, what does y equal?" So, to answer the question, substitute each x value into the equation and solve.

1) Start with the x value of 1. Substitute 1 for x in y = 2x - 1 and solve:

[tex]y = 2(1)-1\\y = 2 - 1\\y = 1\\[/tex]

So, when x equals 1, y equals 1. Therefore, the first box on the top must be filled out with the number 1.

2) Do the same with the rest of the x values. Here are the steps to solve each one, going in order from the top towards the bottom:

x = 0

[tex]y = 2(0) - 1\\y = 0 - 1\\y = -1[/tex]

x = -1

[tex]y = 2(-1) - 1\\y = -2 -1 \\y = -3\\[/tex]

x = 2

[tex]y = 2(2)-1\\y = 4-1\\y = 3\\[/tex]

Answer:

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

x  =  4

$676.8

Step-by-step explanation:

all you need to do is subtract jared's commission from the value of jewelry sold

720-43.20= 676.8

Answer:

x = 10

Step-by-Step Explanation:

Since this triangle is an isosceles, that means two sides are the same and so being that two sides are the same, we can use this equation (5x - 3) • 2.

At first I tried 5, but soon after realized that it wouldn't be enough to make 104, so I doubled the number to 10.

x = 10

((5 • 10) - 3) • 2

(50 -3) • 2

47 • 2 = 94 ( sum of the two equal sides)

94 + 10 = 104

1. We need to get rid of all the denominator in this equation.

12/x = 8 is now 12 = x * 8

1a. 8 * x = 8x

Now, your answer is 3/2, but It's improper. Let's convert it into a mixed number.

Subtract 3 by 2.

3 - 2 = 1

3/2 = 1 1/2

Therefore, your answer is 1 1/2. Also, the answer is 1.5.

Answer: Sue's change will be $57.20

Step-by-step explanation:

Sue bought 2 pairs of jeans and a belt for $6.95.

Sue also paid a tax of $5.85 for the items.

Sue gave the cashier $70, her change will therefore be:

= 70 - 6.95 - 5.85

= $57.20

Answer: 15.199

Step-by-step explanation:

Using the Pythagorean theorem, we know that a²+b²=c²

In this case, we know that c is 16, and that b is 5.

We can rearrange the equation so that it becomes a²=c²-b²

a²=16²-5²

a²=256-25

a²=231

√a²=√231

a=15.199

Answer:

False

Step-by-step explanation:

It was the "golden spike" that was driven as the final spike by  Leland Stanford. This spike was driven on the ceremony of completion of new rail project that connects  First Transcontinental Railroad (USA) with the Central Pacific Railroad (Sacramento) and the Union Pacific Railroad (Omaha) on May 10, 1869.

Hence, the given statement is False

Answer:

we conclude that:

[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]

Step-by-step explanation:

Given the expression

[tex]9x^0y^{-3}[/tex]

Apply exponent rule:    [tex]a^{-b}=\frac{1}{a^b}[/tex]

[tex]\:9x^0y^{-3}=9\cdot \:\frac{1}{y^3}x^0[/tex]

Apply rule:   [tex]a^0=1,\:a\ne \:0[/tex]

             [tex]=9\cdot \:1\cdot \frac{1}{y^3}[/tex]

Multiply fractions:   [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]

              [tex]=1\cdot \frac{1\cdot \:9}{y^3}[/tex]

Refine

               [tex]=\frac{9}{y^3}[/tex]

Thus, we conclude that:

[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]

Mental math:  How many do I need to make up the difference?

counting by 5s:  5, 10 15, 20.  

6 is one more than 5.

From 5, three more 5's gets us close to 20.  It works.

6 + 15 = 21
