Answer:
False
Step-by-step explanation:
the slope is -2/1 AKA -2 so it is negative

Answer:
the point where the graph crosses the y-axis.
Step-by-step explanation:
I took the quiz and this was the correct answer
Total throws = 187
Let three throws = 3t
And
Seven throws = 7s
So
3t + 7s = 187 -------------- (1)
While total collected money = $57
Money for three throws = 1t
Money for seven throws = 2s
Hence
1t +2s = 57 ------------------(2)
Now solving both equations, so multiply second
equation by 3 and subtract it from equation (1);
Equation (2) becomes 3t + 6s = 171
While subtracting it from equation (1) gives the
final equation as below.
s = 16
Putting s = 16 in equation (2);
1t + (2x16) = 57
1t + 32 = 57
t = 25
Thus 25 people bought three throws and 16 people
bought seven throws.
As for 25 people having three throws = $25
And
16 people having seven throws = 2x16 = $32
So total earned money = 25 + 32 = $57

Answer:
Step-by-step explanation:
as given j=h and k=m then which expression for g is
as from attached image , we can see that its look like two right angle triangle
so from lower triangle we apply the pythagorean theorem .
which state that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
so small triangle ΔEBD
h² +k²= g² ---------------(1)
now from big triangle ΔABC
(j + h)² +(m + h)² =f²---------(2)
given j=h and k=m so from equation-2 we can find ,
(h + h)² +(k+ k)² =f²
(2h)² +(2k)²=f²
4h²+ 4k²= f²
4(h²+k²)= f² ----------(3)
now from equation 1 and 3 we can obtained .
4×g² =f²
take square root both side we get,
2×g=f
so g=f/2----- Answer
