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.

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

Supplies for last year cause 1477 which was 177 over the budget rounded to the nearest one percent by what percent did it cost to see the budget cost
Answer:
About 12%
Step-by-step explanation:
Answer:
The cost exceeded the budgeted cost by 14%
Step-by-step explanation:
Supplies for last year cost 1,477, which was 177 over budget. So, the budgeted cost was: 1477 - 177 = 1300
Suppose, the cost of supplies exceeded the budgeted cost by
So, the amount of exceeded cost dollar.

Mr. Dyer is studying a map. The map has a scale that says 1.5 inches is equivalent to 125 miles. Mr. Dyer measures and sees that two cities are half a foot apart. He has enough gas in his truck to travel 580 miles. Can he make it from one city to the other on the gas in his truck?
Answer: Yes he can make the trip without having to refuel.
The distance between the two cities is 500 miles.
================================================
Work Shown:
half a foot = 1/2 ft = (1/2)*(12 inches) = 6 inches
Based on the scale given, we can say,
(map length)/(real length) = (map length)/(real length)
(1.5 inches)/(125 miles) = (6 inches)/(x miles)
1.5/125 = 6/x
1.5x = 125*6 ............. cross multiply
1.5x = 750
x = 750/1.5 .......... divide both sides by 1.5
x = 500
The two cities are 500 miles apart. Since this is less than 580, he can make the trip without having to refuel.
This is assuming he drives directly from the first city to the second, without any additional pitstops or detours. Though in reality, straight line distance on a map doesn't always necessarily correspond to the road distance traveled (since the road tends to wind or curve often). However, for the sake of this problem, we'll just assume the road is a straight line to keep things simple.
----------------------------------------
Another approach:
1.5 inches = 125 miles
3 inches = 250 miles ..... multiply both sides by 2
6 inches = 500 miles .... multiply both sides by 2
half a foot = 500 miles
So half a foot on paper corresponds to 500 miles in real life.

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

Required Answer:-Marta predicted correctly 6 out of 13 football games .
We need to find first Her's Current percentage[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6}{13}}\times 100 [/tex]
[tex]\longrightarrow[/tex][tex]\sf {\dfrac {600}{13}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf 46.15\% [/tex]
Now We need to add x in both denominator and numerator[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6+x}{13+x}}={\dfrac {65}{100}} [/tex]
Simplify use cross multiplication method[tex]\longrightarrow[/tex][tex]\sf 100 (6+x)=65 (13+x)[/tex]
[tex]\longrightarrow[/tex][tex]\sf 600+100x=845+65x [/tex]
[tex]\longrightarrow[/tex][tex]\sf 100x-65x=845-600 [/tex]
[tex]\longrightarrow[/tex][tex]\sf 35x=245 [/tex]
[tex]\longrightarrow[/tex][tex]\sf x={\dfrac{245}{35}}[/tex]

So the new rational number[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6+x}{13+x}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf {\dfrac {6+7}{13+7}}[/tex]
[tex]\longrightarrow[/tex][tex]\sf {\dfrac {13}{20}}[/tex]

Clare wants to make an open-top box by cutting out corners of a 30 inch by 25 inch piece of poster board and then folding up the sides. The volume, `V\left(x\right),` in cubic inches of the open-top box is a function of the side length, `x,`in inches, of the square cutouts.
Answer:
V(x) = 4x³ - 110x² + 750x
Step-by-step explanation:
For each side of the base of the open-top box, since x inches is cut out from each side, we have 2x inches removed from each sides dimension.
Since the dimensions of the poster are 30 inches by 25 inches, the area of the base of the open-top box is thus
A(x) = (30 - 2x)(25 - 2x) since we remove 2x inches from each dimension.
Now, the height of the open-top box is x. So, its volume is V(x) = Ax
V(x) = (30 - 2x)(25 - 2x)x
V(x) = (750 - 60x - 50x + 4x²)x
V(x) = (750 - 110x + 4x²)x
Expanding the bracket, we have
V(x) = 750x - 110x² + 4x³
Re-arranging, we have
V(x) = 4x³ - 110x² + 750x
