Slope intercept form is y=mx+b
m=slope
b= y intecept

points in (x,y) form

one solution is
x=8
y=3
m=6
subistute and solve for b
3=6 times 8+b
3=48+b
subtract 48 from both sides
-45=b

the equation is y=6x-45

the answer is actually B because if you do the math
y-3=6 times (x-8)
distribute
y-3=6x-48
add 3 to both sides
y=6x-45

the ANSER IS B

Y=mx+b
m=6
y=6x+b
x=8, y=3

3=6*8+b
3=48+b
b=3-48
b=-45
y=6x-45

B. y-3=6(x-8)

A $12 t- shirt is on sale for 40% off at a store in Mississippi. Sales Tax on Mississippi is 9%. How Much Will The t- shirt end

STALIN [3.7K]

Let's calculate how much for the $12 t - shirt after the discount.

First, convert 40% into a decimal,

$40\% = 0.4$

Next, multiply the cost by the discount,

$12 \times 0.4 = 4.8$

Lastly, subtract the amount discounted,

$12 - 4.8 = 7.2$

~~

Now

Let's calculate the amount after the sales tax,

First convert 9% to a decimal,

$9\% = 0.09$

Next, multiply the cost of the t - shirt by the sales tax,

$7.2 \times 0.09 = 0.648 = 0.7$

Lastly, add the amount of sales tax to the price of the t - shirt,

$7.2 + 0.7 =7.9$

~~

Answer : the t - shirt will be $7.90 after everything.

~~

I hope that helps you out!!!

780 at 5.25 for 10 months what is the amount of simple interest

Annette [7]

Answer:

$814.13

Step-by-step explanation:

Recall that the simple interest formula is a=p(1+rt).

a= final amount (Unknown)

p=starting amount ($780)

r= interest rate (5.25= 0.0525%)

t=time in years (10 months =5/6 years)

Plug numbers into formula:

a=780(1+5.25*5/6)

Solve parenthesis first according to PEMDAS:

a=780(1.04375)

Multiply:

814.125

Round to nearest hundredth (cent):

$814.13

Which of the following is not a way to represent the solution of the inequality 2(x− 1) ≤ 10?

sertanlavr [38]

Answer: D. A number line with a closed circle on 6 and shading to the right

Step-by-step explanation:

Here, the given inequality,

2(x− 1) ≤ 10

2x - 2 ≤ 10

2x ≤ 10 + 2

2x ≤ 12

x ≤ 6 or 6 ≥ x

The value of x is all numbers less than 6 including 6.

⇒ A number line with a closed circle on 6 and shading to the left.

Thus, by the above explanation,

Only option D 'A number line with a closed circle on 6 and shading to the right' is not a way to represent the solution of the inequality.

Leo runs the 100-meter dash in 19.305 seconds. Explain and show how you can write an expression in expanded form for the decimal

Ugo [173]

An expression in expanded form for the decimal that shows more than 0 hundredths is 19.31

<h3>How to write an expression in expanded form for the decimal that shows more than 0 hundredths.</h3>

The time is given as:

Time = 19.305

The hundredth in the above number is 0

So, to write an expression in expanded form for the decimal that shows more than 0 hundredths;

We simply approximate 19.305

So, we have:

Time = 19.31

Hence, an expression in expanded form for the decimal that shows more than 0 hundredths is 19.31
