Answer:
12
Step-by-step explanation:
Draw a number line from -10 to +10 with tick marks (division lines) every 1 unit. Now find the origin (in the middle of the line you have just drawn). Now move your pencil point 3 units to the left and plot a dark (closed) dot there. Then draw a ray from that closed dot to the left. Apparently we cannot extend that ray beyond -10.
(-10,-3] would be my representation of this situation.
Answer:
It's a parabola.
Step-by-step explanation:
direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
Answer:
My best answer. Hope this helps...
Step-by-step explanation:
You can see 1 full square in the triangle.
There are also 3 half squares.
The top part of the triangle also equals to 1 half square.
On the bottom right side, you have two shapes that add up to a square.
4 half squares = 2 full squares.
2 + 1 + 1 = 4
The square also has 4 squares.
