Which inequality is true when the value of R is 18? I'ma shower the answers i can choose in the picture ​

Answers

Answer:

See below:

Step-by-step explanation:

Hello! We can check to see if the inequality is true by replacing r with 18 as we have been told to find them in which 18 as r makes the equation true.

So our equations to test for are:

[tex]-r-3>-6\\-r+3<6\\r+3<6\\-r+3>6[/tex]

We can input 18 as r and then we see the following are correct:

1. No, as a -21 is not greater than -6

2. Yes, as -15 is less than 6.

3. No, as 21 is not greater than 6

4. No, as -15 is not greater than 6.

B The graph of g(x) reflects the graph of f(x) across the y-axis.
CThe vertex of the graph of g(x) is 6 units to the left of the vertex of the graph of f(x).
DThe y-intercept of the graph of g(x) is 6 units above the y-intercept of the graph of f(x).

Two trains leave towns 474 kilometers apart at the same time and travel toward each other. One train travels13 km/m faster than the other. If they meet in 2 hours, what is the rate of each train?

Answers

Answer:

112 km/h

125 km/hr

Step-by-step explanation:

Distance = time * speed

Distance  = distance train 1 + distance train 2

474 = 2(s) + 2(s + 13)

Distribute

474 = 2s + 2s + 26

Combine like terms

474 = 4s + 26

Subtract 26 from both sides

448 = 4s

Divide both sides by 4

112 = s

s = 112 km/h

s + 13 = 125 km/hr

What is the length of side YZ to the nearest tenth please show your work!

Answers

Length of side YZ to the nearest tenth is 16 ft

To solve this question we would use the sine rule. The sine rule states that

A/sin a = B/sin b

if we take our angle a to be XZY, and b to be ZXY.

Going by angles in a triangle, ZXY = 180 - 90 - 35 = 55. This means that our angle b is 55º

applying the sine rule, we have

11/sin 35 = B/sin 55

11/0.5736 = B/0.8192, if we cross multiply, we have

B = (11 * 0.8192)/0.5736

B = 9.0112/0.5736

B = 15.7 ft

Che sum of two numbers is 2. If one number is subtracted from the other, their difference is - 8. Find the numbeRs

Answers

I wanna say 10 or ether -10 since if it was subtracted from 2 then it would equal -8

Answer:

1st number (x) = -3, 2nd number (y) = 5

Step-by-step explanation:

x + y = 2, y = 2 - x

x - y = -8, y = x + 8

By substituting y = 2 - x in the other equation:

(2 - x) = x + 8

2 - 8 = x + x

-6 = 2x

x = -3

Now plug x = -3 into either equation:

y = 2 - x

y = 2 - (-3) = 5

So the numbers are -3, 5

A special cereal mixture contains rice and wheat in the ratio of 2:3. If a bag of the mixture contains 3 pounds of rice, how much wheat does it contain?

Answers

9514 1404 393

Answer:

  4.5 lb

Step-by-step explanation:

The ingredients are proportional so ...

  wheat/rice = 3/2 = ??/3 lb

Multiplying by 3 lb gives ...

  ?? = (3 lb)(3/2) = 9/2 lb = 4.5 lb

The mixture contains 4.5 lb of wheat.

the test and 20 students who completed the assignment. There
were 13 students who passed the test and also completed the
assignment. What is the probability that a student passed the test
given that they did not complete the homework?
a

Answers

Using it's concept, it is found that there is a 0.4 = 40% probability that a student passed the test given that they did not complete the homework.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, of the 25 - 20 = 5 students that did not complete the homework, 15 - 13 = 2 passed the test, hence the probability is given by:

p = 2/5 = 0.4 = 40%.

0.4 = 40% probability that a student passed the test given that they did not complete the homework.

find an equation for the line below

Answers

Answer:

y = 1/3 x + 14/3

Step-by-step explanation:

We can identify the two points shown easily.

They are (-2, 4) and (4, 6).

First, we find the line of the slope of the line that contains those two points.

slope = m = (y2 - y1)/(x2 - x1) = (6 - 4)/[4 - (-2)] = 2/6 = 1/3

Now we use one point and the slope to find the y-intercept.

y = mx + b

Let's use point (4, 6) and the slope, 1/3.

6 = (1/3)(4) + b

18/3 = 4/3 + b

b = 18/3 - 4/3

b = 14/3

The equation is

y = mx + b

y = 1/3 x + 14/3
