9) Area of Figure = Area of rectangle + area of triangle
A = 17 * 22 + (1/2 * 12 * 19)
A = 374 + 114
A = 488 cm²
10) Area of Figure = Area of rectangle + area of triangle
A = 8 * 4 + (1/2 * 3*4)
A = 32 + 6
A = 38 cm²
Hope this helps!
Answer:
20
Step-by-step explanation:
x^2+18x-160
If you put this into your calculator or desmos, you will get a parabola. You want to know the value of x when y=600. You can look at the table for the graph or scan to where y = 600. The value of x is 20 at that point.
To check you can plug 20 in for x. When you do that, y = 600.
Answer:
B.
Step-by-step explanation:
The X-values are between -1 and 5. --> -1 ≤ x ≤ 5
The Y-values are between -4 and 2. --> -4 ≤ Y ≤ 2
Looking at the answer which matches up with these, you get B.
Answer:
x=-1
y=10/3
Step-by-step explanation:
You can solve the system of equations by applying the elimination method as following:
- Add both equations, then:

- Finally, you must substitute the value of x obtained into one the original equations and then you must solve fot y:

Answer:
20 hours.
Step-by-step explanation:
All you would do is divide. 900 divided by 45 is 20.
