Answer:
f(1)=0; f(0)= -2; f(-1)=(-4); f(2)=2
Step-by-step explanation:
For the first four questions, f(1) means that x= 1, so you need to look at the graph, find the point where x= 1, and find the corresponding y value which is 0. You do this same process for each of the rest.
For 5 and 6: when they say f(x) = some value, this is the y value. So look at the graph: when y = 4, you can see that x = 3. When y = -6, you can see that x= -2.

Step-by-step explanation:
12 inches is in a foot
10 x 7= 70
2 x 7= 14
70+14=84
Answer:
(5, -18)
Step-by-step explanation:
the original formula for the circle is (x – h)2 + (y – k)2 = r2 the center is (h, k)
so,
(x - 5)2 + (y + 18)2 = 36
h= 5, k=-18
Answer:
x= 60°, y = 80°, z = 40°
Step-by-step explanation:
Look at the line substending 40° and Z°; you would see that both lines are parallel and so their angles are they the same.
Hence z= 40° { corresponding angles of parallel lines}
Similarly;
Look at the line substending 60° and x°; you would see that both lines are parallel and so their angles are they the same.
60° = x° { corresponding angles of parallel lines}
Now looking at the angle between x and y; let's call the angle between them r
And you would observe closely that r = z° = 40°{ vertically opposite angles are equal}
Note that x + r + y = 180°{ angle on a straight line}
y = 180° - ( x + r)
y = 180 - (60+40)
y = 180° - 100°
= 80°
800= about 1.76 lbs
700= about 1.54 lbs
(there are about 453.5 grams in a pound
