Answer:

y=0.5x+8

Step-by-step explanation:

Use the formula for the equation of a line y=mx+c where m is the slope and c is a number.

To find the slope, take two points (x₁,y₁) (x₂,y₂) and put them into the slope equation m=(y₂-y₁)/(x₂-x₁):

We can take two points from the graph: (2,9) (4,10)

m=(y₂-y₁)/(x₂-x₁)

m=(10-9)/(4-2)

m=1/2 or 0.5

Now sub this value in for m and our formula looks like this:

y=0.5x+c

To find the value of c, sub in one of the points, eg. (4,10)

y=0.5x+c

10=0.5(4)+c

10=2+c

c=8

So now that we now m and c, our equation is complete :D

y=0.5x+8

Answer:

Step-by-step explanation:

The slope-intercept equation for a line is y = mx+b, where m is the slope and b is the y-intercept.

Refer to the picture. You can see that the line crosses the y-axis at (0,8), which means the y-intercept is 8.

The graph shows the path of a hiker walking up the hill. When he goes from one blue dot to the next, he has moved 2 units to the right and 1 unit up. The slope of the hill is ½.

Slope-intercept equation for line of slope ½ and y-intercept 8:

y = ½x+8

There is nothing to simplify.

James earned $334 for working a 40-hour week how much will he earn in a week in which he works only 32 hours
atroni [7]

$267.20

Divide $334 by 40 for hourly rate then multiply by 32

earnings = \frac{334}{40} × 32 = $267.20

John went on a bike ride to the store 4 miles away. If it took John 3/10 of an hour to get there and 1/2 of an hour to get back,
stiv31 [10]

The round trip was 8 miles ( 4 + 4 = 8)

The total time for the trip is 3/10 + 1/2

Rewrite 1/2 as 5/10

Now add 3/10 + 5/10 = 8/10 = 4/5 hour for the 8 mile trip.

Now to find miles per hour, divide total miles by total time:

8 miles / 4/5 hour

When you divide by a fraction flip the fraction over and multiply:

8 x 5/4 = 40/4 = 10

The average rate was 10 miles per hour.

Please help out it for my math homework and I sure do have more questions
GalinKa [24]

Answer:

30°

Step-by-step explanation:

Remember, all the interior angles of a triangle add up to 180 degrees. Therefore, we can find the value of x by subtracting the values of the other angles from 180:

x = 180-97-53

x=30
