Answer:
2.25
Step-by-step explanation:
to find slope it is (y2-y1)/(x2-x1)
(15.25-8.50)/(5-2)
6.75/3
2.25 is the slope
Hello there! Your answer would be y = 0.5x - 3.
To find the equation, use slope intercept form, y = mx + b. <em>(m = slope, b = y intercept)</em>
For the slope, solve by subtracting the y values over the x values.
- 5 - - 3 / 0 - 4
- 2 / - 4
The negatives cancel out, and you are left with 0.5 as your slope. Plug that into m.
y = 0.5x + b
Now to find the y intercept. To do this, we can replace the x and y values into the equation and solve for b.
-5 = 0.5(4) + b
-5 = 2 + b
- 3 = b
so, the y intercept has a value of -3. Plug that in to the final equation.
y = 0.5x - 3
Hope this helps and have a great day!
Answer:
no. who eat lunch special = 12
no. who eat dessert = 6
Step-by-step explanation:
Let x = no. who eat lunch special
y = no. who eat dessert
(1) 8x + 2y = 108 (2) 6x + 3y = 90
Divide thru by 2 Divide thru by 3
4x + y = 54 2x + y = 30
<u>-2x - y = -30</u>
2x = 24
x = 12 2(12) + y = 30
24 + y = 30
y = 6
Answer:
12

Answer:
<em>h = 3</em>
Step-by-step explanation:
What we have here is a classic case of pythagorean theorem. 5 is the hypotenuse and 8 is divided directly in half to make one of the legs equal to 4. inputting this into the pythagorean equation we get 4^2 + h^2 = 5^2 or 16 + h^2 = 25. 25 - 16 = 9 and the square root of 9 is 3. therefor <em>h = 3</em>
