Answer:

14

Step-by-step explanation:

You solve this problem by subtracting 3 from 10 because you have to solve it inversely. After doing this you get 7. Since that is 1/2 a number the number is 14

Answer:

14

Step-by-step explanation:

Let's call the number x.

\dfrac{x}{2}+3=10

Subtract 3 from both sides:

\dfrac{x}{2}=7

Multiply both sides by 2:

x=14

Hope this helps!

Danielle plans to graph the linear equation 5x-2y=10 by plotting the x-intercept and y-intercept.
lesya692 [45]

x-intercept is (2,0)

y-intercept is (0,-5)

Step-by-step explanation:

Danielle plans to graph the linear equation 5x-2y=10 by plotting the x-intercept and y-intercept.

Finding x-intercept

X-intercept: Substitute 0 for y and then solve for x. Write your answer in the form (__, 0)

Putting y=0

5x-2y=10\\5x-2(0)=10\\5x=10\\x=10/5\\x=2

So, x-intercept is (2,0)

Finding y-intercept

Y-intercept: Substitute 0 for x and then solve for y. Write your answer in the form (0, __)

Putting x=0

5x-2y=10\\5(0)-2y=10\\-2y=10\\y=10/-2\\y=-5

So, y-intercept is (0,-5)
