Answer:

y-intercept: 32.575

slope: 0.216

Step-by-step explanation:

In y = mx + c

c is the y-intercept

m is the slope

y=0.216x + 32.575

c = 32.575

m = 0.216

Using the equation of best fit provided:

y=0.216x + 32.575

The slope is the number with the x, so the slope is 0.216 and the y- intercept is the number added at the end. The y intercept is 32.575

13. Translate the following verbal phrase
Artyom0805 [142]

a) algebraic expression

\frac{3+x}{5}=10

b) Solve and find value of x

x=47

Step-by-step explanation:

We need to translate the following verbal phrase  into an algebraic equation

The quotient of three more than a  number and five is ten

Let the number be x

three more than a  number is written as: 3+x

Since quotient is 10 so,

The algebraic expression will be:

\frac{3+x}{5}=10

Now, <u>solving to find value of x</u>

\frac{3+x}{5}=10

Multiplying both sides by 5

\frac{3+x}{5}*5=10*5\\3+x=50

Now Subtract -3 from both sides

3+x-3=50-3\\x=47

So, value of x=47

coach Cliffman made a deposit of $1800 into an account that earns 2% annual simple interest. find the amount of interest that co
NeX [460]

Answer:

The amount of interest Coach Cliffman earned after 3 years is $108.

Step-by-step explanation:

The equation for simple interest is A = P(1 + rt). To determine the revenue earned, subtract the principal amount ($1800) from the total accured amount (principal + interest). The equation for simple interest is A = P(1 + rt), <em>P </em>meaning principal interest, <em>r</em> being the rate of interest per year in decimal form, and <em>t</em> as time in years.

Let P = $1800, r = .02, and t = 3 and you'll end up with a total accrued amount of $1908. Finally, subtract 1908-1800 to get your answer of $108.

Please help if you can &lt;3
Bogdan [553]

Answer:

1) x = 71

2) x = 117

5)

m<1: 35

m<2: 77

m<3: 52

m<4: 77

m<5: 65

m<6: 25

Step-by-step explanation:

1)

x + 41 + 68 = 180

x + 109 = 180

x = 71

2)

x + 47 + 16 = 180

x + 63 = 180

x = 117

3)

<2 + 103 = 180

<2 = 77

<1 + 68 + 77 = 180

<1 + 145 = 180

<1 = 35

<4 + 103 = 180

<4 = 77

<5 + 41 + 77 = 180

<5 + 115 = 180

<5 = 65

<6 + 65 = 90

<6 = 25

<3 + 103 + 25 = 180

<3 + 128 = 180

<3 = 52

AnnZ [28]

38 + 7x - 21 = 9x + 9

Combine like terms.

17 + 7x = 9x + 9

Eliminate a x.

17 = 2x + 9

8 = 2x

x = 4
