The length of a rectangle is twice its width. If the rectangle's perimeter is 200
inches, what are the length and width of the rectangle?
Step-by-step explanation:
set that width is x
and length become 2X
P = 2×( X+ 2X )
200 = 6 X
X=33. 3
width = 33.3 inch
length = 66. 6 inch
Which of these tables best represents the equation y = 5x – 8
The best and only represents the equation y = 5x – 8 is done in the table C.
What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given a linear equation y = 5x - 8
As we can see that this equation has a slope of 5 and a y-intercept of -8
To ease the process we will calculate the value of y at different values of x:
For x = 0 ,
y = 5 * 0 - 8 = -8
For x = 1
Y = 5-8 = -3
For x = 2
Y = 5*2 - 8
y = 2
For x = 3
y = 5*3 -8
y = 7
for x = 4
y = 20 *8
y = 12
Since only table C is satisfying the situation.
therefore, The best and only represents the equation y = 5x – 8 is done in table C.

Complete Question:
A line with a slope of 8 passes through the points (-1,1) and (0,k). What is the value of k?
Answer:
k = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 8
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)
m = [tex]\frac{k-1}{0+1}[/tex] = k - 1 = 8 ( add 1 to both sides )
k = 9

For every $9 invested in company A, $2 is invested in company B. Stacey quizzes her children, Krista and Kevin, about how much money she will invest in company A if she invests $24 in company B. Krista and Kevin used two different methods to arrive at the answer to Stacey's problem. Let's see who found the correct answer and how. You'll answer some questions along the way.
Answer:
$108
Step-by-step explanation:
From the above question, we have the proportion:
Company A/Company B
= $9/$2 = x/x24
The next step is : We Cross Multiply
2x = $24 × $9
x = $24 × $9/2
x = $108
Therefore, she will invest in $108 company A if she invests $24 in company B.

Which equation describes the line with slope 5, that contains the point (-2, 4)?
a: y = 5x - 22
b: y = 5x - 2
c: y = 5x + 4
d: y = 5x + 14
Answer:
C
Step-by-step explanation:
Answer:
D.) y=5x+14
Step-by-step explanation:
point slope form: y-y1=m(x-x1)
y1=4, m=5, x1=-2
y-4=5(x+2)
distribute 5
y-4=5x+10
add 4 to both sides
y=5x+14

A boat leaves Astoria and travels upstream on the Columbia river for 5 hours. The return trip only takes 3.6 hours because the boat travels 4 miles per hour faster downstream due to the current. How far does the boat travel up the Columbia? Suppossed to solve as an in equality?
Answer:
10.285 miles
Step-by-step explanation:
Given that:
Upstream travel time = 5 hours
Return trip travel time = 3.6 hours
Let upstream travel speed = x mph
Downstream travel speed = x + 4 mph
Distance = speed * time
Upstream distance = x * 5 = 5x
Downstream distance = (x + 4) * 3.6
5x = (x + 4) * 3.6
5x = 3.6x + 14.4
5x - 3.6x = 14.4
1.4x = 14.4
x = 10.285714
x = 10.285 miles
