if 2x+y=8 and x+2=5. what is the value of y?​

Answers

Answer 1

Answer:

y=2

Step-by-step explanation:

x+2=5

x= 5-2

x= 3

2x+y=8

2×3+y=8

6+y=8

y=8-6

y=2

Answer 2

Answer:

y=2

Step-by-step explanation:

First solve x+2=5 to find x.

x+2=5

  -2  -2

x=3. Substitute x=3 into 2x+y=8.

(2 x 3) + y = 8

Now solve.

6 + y = 8

-6         -6

y=2.

There are 1,000 meters in 1 kilometer. How many kilometers are in 3,600 meters?


HELP

Answers

Answer:

A. 3.6 kilometers

Step-by-step explanation:

1000 meters = 1 km

3600 meters = x km

Set as a ratio:

1000 : 1 = 3600 : x

Then divide:

[tex]\frac{3600}{1000} = \frac{x}{1} = x[/tex]

so 3600/1000 = 3.6 = x

3.6 km

Using the graph below, what would the input (x-value) need to be for an output (y value) of 1?

Answers

Answer:

X = 2

Y = 1

The graph intersects at the exact point of (2,1)

The value of x or the input value is 2 for which the output or the value of y is 1.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a graph of a line shown in the picture

As we can see the line passes through the points (3, 3) and (0, -3)

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The equation of  the line passes through the points:

( y + 3) = (-3-3)/(0-3)[x - 0]

y + 3 = 2x

y = 2x - 3

Plug y = 1

1 = 2x - 3

2x = 3 + 1

2x = 4

x = 4/2

x = 2

Thus, the value of x or the input value is 2 for which the output or the value of y is 1.

To simplify you need to turn it into an improper fraction. This means that the numerator (the number on top) is greater than the denominator (the number on the bottom). The improper fraction form of 5 6/18 is 96/18. I believe this is the answer to your question.

If L(2, 7) is an endpoint of a line segment, and M(8, 3) is the midpoint, find the other endpoint of the segment.

Answers

Answer:

Step-by-step explanation:

From L to M,

change in x-coordinates = 8-2 = 6

change in y-coordinates = 3-7 = -4

Extrapolate from M(8,3) to find the other end of the segment:

8 + 6 = 14

3 - 4 = -1

Endpoint of segment: (14,-1)

The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 3. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 59 and 62

Answers

Answer:

About 34%

Step-by-step explanation:

Given that :

Mean, m = 59 ; Standard deviation, s = 3

Bulb replacement numbering between 59 and 62

For, x = 59

Zscore = (x - m) / s

Z = (59 - 59) / 3 = 0

For x = 62

Z = (62 - 59) / 3 = 1

P(Z < 1) - P(Z < 0)

0.84134 - 0.5

= 0.34134

Thank you.

Answers

Answer:

B. 40

Step-by-step explanation:

We know that the large angle is 90 degrees as it is a right angle. Thus, [tex]10+2x=90[/tex] (I don't know how to include degree symbols). We solve: [tex]2x=80[/tex], so then [tex]x=40[/tex]. Thus, x is forty degrees and the answer is B.

Answer:

40

Step-by-step explanation:

There is a bisector splitting a 90-degree angle into 2 parts, we are given that one of them is 10. This can only mean the other side is 80 degrees in total.
