Help pls!! What additional information is needed to prove that RSTU is a rectangle?

Answer: The break-even point is x = 15

Step-by-step explanation:

We have the equations:

c(x) = 10*x

r(x) = 210 - 4*x

I suppose that c(x) is the cost equation, and r(x) is the revenue equation.

"break-even" means that you don't lose nor win anything, then the difference between the revenue and the cost is 0.

Then we need to solve:

r(x) - c(x) = 0

(210 - 4*x) - (10*x) = 0

210 - 4*x - 10*x = 0

210 - 14*x = 0

210 = 14*x

210/14 = x

15

This means that for x = 15, you break even.

Answer: If this isnt wrong then I probably forgot how to do this... You plug in 10 with [tex]\pi[/tex]10^2. so then you'll get 100 time pi and youll get 314.159265.

Answer:

B and C

Step-by-step explanation:

5 * (7 + 6s - 9t) = 7*5 + 6s *5  - 9t*5

                       = 35 + 30s - 45t

(-35 - 30s + 45t)*(-1) = (-35)*(-1) - 30s *(-1) + 45t*(-1)

                               = 35 + 30s - 45t

Answer: x= 19.5

(4x+12) = 90

Step-by-step explanation:

Notice the denoted right angle at the very top left. This means those intersecting lines are perpendicular forming 90 degree angles. All right angles are equal in measure so all 4 angles at the top are 90 degrees. We can then use corresponding angles to know that all of the bottom 4 angles are also 90 degrees. Now we can solve for x. (4x+12) =90. 4x= 78. X= 19.5

Answer:

Perpindicular

Step-by-step explanation:

Use the Slope formula to find the Slope of the line through each pair of points.

y2 - y1 / x2 - x1

12 - 3 / 4 - 2 = 9/2 is the first Slope.

8 - 10 / 14 - 5 = -2/9 is the Slope of the second line.

The slopes are negative reciprocal, perpendicular.

Answer:

y = 3x

Step-by-step explanation:

The line goes up 3 and goes across by 1. Using the rise over run structure, it will be 3/1 or 3. m is equal to the slope, making it y = 3x, since y doesn't intercept anything, you don't need to put + anything at the end. Hope I helped. :D

Answer:

The fountain has a circumference of 9 feet.

Step-by-step explanation:

5 and above get rounded to the next tenth and 4 and below rounds to the nearest 10 also and that would be 9 if it was 9.5 or above the answer would have been 10.0

Given:

Diameter of a tire = 33 inches.

To find:

The distance covered by the tire if it rotates one time.

Solution:

We have,

Diameter of a tire = 33 inches.

Radius is the half of diameter. So, the radius of the tire is

[tex]\dfrac{33}{2}=16.5[/tex]

Thus, r = 16.6 inches.

We have to find the distance covered by the tire if it rotates one time. It means, we need to find the circumference of the tire.

[tex]C=2\pi r[/tex]

[tex]C=2(3.14)(16.5)[/tex]

[tex]C=103.62[/tex]

Therefore, the distance covered by the tire if it rotates one time is 103.62 inches.

Step-by-step explanation:

The sum of the angles of a triangle is always 180°.

(2x+4) + (2x-2) + (x-2) = 180

5x = 180

x = 36°

Answer:

Parallel lines have the same slope, so any line parallel to y = 7x - 3 will have slope 7. If your y intercept is 5, the line must go through (0,5), giving you y = 7x + 5.

Question:

x + 3 < 5, Find x.

Answer

⟹ x + 3 < 5

( Subtracting 3 from both the sides of the inequality )

⟹ ( x + 3) - 3 < 5 - 3

⟹ x < 5 - 3

⟹ x < 2

It means that any number that is smaller than 2 will satisfy the inequality.

Answer:

parallel : (b) and (g)

perpendicular : (d) and (f)

Step-by-step explanation:

straight line equation : y = mx + c

Lines that are parallel have the the same gradient(m),

(b) and (g) are parallel, both of them has m= 1/2

Lines that are perpendicular will have the product of their

gradient(m) equal to -1. So, m1 × m2 = -1

(d) and (f) are perpendicular, because : -4 × ¼ = -1
