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

X= (Type an integer or a simplified fraction.).
Answer:
The answer is x=-1/7
Step-by-step explanation:
11-6x-7-8x=6
Combine like terms
11-7-6x-8x=6
4-14x=6
4-4-14x=6-4
-14x=2
To find x divide both sides by -14
-14x/-14=2/-14

Answer:
(49x + 18) + 49y
Step-by-step explanation:
you woud place the variable (letter) representing the number of weeks they worked by the amount they get paid each week then, you would add to whoever gets an extra amount of money, the y - intercept or in this case the extra 18 dollars one of them gets paid to whoever got paid that amount of extra money. :)

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.

Answer:
c
Step-by-step explanation:
a is not enough information because the measure of angle 2 could be another random value
b is not correct for the same reason as a
d is not correct because those two angles do not equal 90
c is correct because of a theorem, so basically if you have two angles, and they have segments at 90 angles placed in the specified spots, they are on the bisector

The scatterplot below shows the number of coupons that are used at the grocery store and amount of money that is saved. A graph titled Coupon Use and money saved has number of coupons used on the x-axis, and coupon savings (dollars) on the y-axis. Points are grouped together and increase. Which statement about the scatterplot is true? As coupon use decreases, the amount of savings increases. As coupon use increases, the amount of savings increases. Regardless of high coupon use, the amount of savings remains low. Regardless of high savings, coupons use remains low.

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

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.
