Find the value of the expression. [(3/5)]-2

The best and only represents the equation y = 5x – 8 is done in the table C.

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:

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

x=-1/7

Answer:

The answer would be 17 cm

Step-by-step explanation:

If the distance between their feet is 12 cm, then the distance between their heads would also be 17 cm, because of their five cm height difference. [ You add that on to their normal distance]. I hope this helped! If I'm wrong, I'm sorry and please let me know... Have a great day!!

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

Step-by-step explanation:

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 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

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

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.

Thus, the equation will be......

13x = 177

x= 177/13 = 13.615 = 14

(Rounded to the nearest 1%)

So, the cost exceeded the budgeted cost by 14%
