Answer:
y − 8 = m(x − 1)
72 minutes
Step-by-step explanation:
Point slope form is: y − y1 = m(x − x1)
Pick any two points. I'll pick (1,8) and (2,16). I will make the first point the (x1,y1) we need for the point slope equation:
y − y1 = m(x − x1)
y − 8 = m(x − 1)
We can calculate the slope, m, by determining the Rise/Run of the line. The Rise is the change in y for the Run, the change in x.
Change in Run (x) = (2-1) = 1
Change in Rise (y) = (16-8) = 8
Slope (Rise/Run) = 8
m is 8
y − 8 = m(x − 1)
y − 8 = 8(x − 1)
or
y = 8x
We can now predict Heather's time to complete the 9 miles:
y = 8x
y = 8*(9)
y = 72 minutes
PLEASE HELP what is x in : x + 11 = 18
The answer is 7
A tip you can do is get the sum subtract the number you do have so you would get your X value. So 18-11=7
Answer: x = 7
------------------------------
x + 11 = 18
x = 18 - 11
x = 7

Find three ratios equivalent to 4/7
If two ratios have the same value when simplified, then they are called Equivalent Ratios.
Equivalent ratios can be obtained by multiplying or dividing both sides by the same non-zero number.
As we want 3 equivalent ration in higher terms we will multiply it

Simplify the expression.
5+2⋅[(2+2)⋅5+5]
Answer:
55
Step-by-step explanation:
Remember PEMDAS
solve parentheses first : (2+2) = 4
Then multiply inside the brackets 4 x 5 = 20
20+5 = 25
Then multiply 2 x 25 = 50
50+5 = 55
Your answer would be 55

Acelynn borrows $1337 to buy a four-wheeler. The annual
intrest rate is 4% for the 14-year loan.How many intrest
will she payfor the money borrowed?
Answer:
$748.72
Step-by-step explanation:
Multiply 1337 times 4%
4% = 0.04
1337 x 0.04 = 53.48
Multiply the product by the amount of years -
53.48 x 14 = 748.72
She will pay back $748.72 intrest for the money borrowed.
The interest rate is 4%. So, it can be written as 0.04
$1337 × 0.04 × 14 = 748.72
So, she'll pay $748.72 interest for the borrowed money...

Step-by-step explanation:
hahahhaha
The required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.
Given that,
To find the products [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd].
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Given expression,
= [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd]
= 1/5a²/b[-2/5ab - 1/6cd] - 1/3[-2/5ab - 1/6cd]
= -2/25a³b² - 1/60abcd +2/15ab + 1/18abcd
= -2/25a³b² + 2/15ab + 7/180abcd
Thus, the required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.

According to the table, what was the hiker’s total displacement?
A.0
B.6 km north
C.10 km northeast
D.20 km
Answer:
A: 0
Step-by-step explanation:
Important to remember - total displacement is the direct distance between the start and finish points, and isn't always equal to the total distance travelled.
In the case of the table above, the hiker travels the same distance in opposite directions, which actually means they cancel each other out! Traveling 4 km to the west, then 4 km to east means you end up in the same spot, right? So your total displacement is 0! (or 4 - 4, which equals 0). Same happens with the north-south hikes - the hiker ends up in the same spot, as the displacement is equal to 6 - 6 = 0.
So, the total displacement of the hiker is 0. (Even though the hiker travelled 20 km!)

Point DD is located at (-2,-6)(−2,−6) on the coordinate plane. Point DD is reflected over the x-axis to create point D'D. Point D'D
is then reflected over the y-axis to create point D''D
What ordered pair describes the location of D''?D
Answer:
(2,6)
Step-by-step explanation:
since DD is at (-2,6) and you're reflecting it just count 6 spaces from the point to the x-axis then go up 6 more the point will be at (-2,6) and if you go to the right 2 spaces to the y-axis then go two more you'll end up at (2,6)
