Answer:
0.699 (=69.9%)
Step-by-step explanation:
Efficiency = total hits / total attempted
given total hits = 51 and total attempted = 73
Efficiency = 51/73 = 0.699 (=69.9%)
I only see part a, so for that one:
f(x) = 2x says that you’ll take your input (your x-value) and multiply it by 2 to get your output (your y-value).
f(7) = 2•7
f(9) = 2•9
f(-11) = 2•(-11)
f() = 2•
In part a, you’re asked for f(2), so this becomes :
f(2) = 2•2
= 4
1. To find the y-intercept, replace x with zero.
2(0)+3y=12
= 3y=12
Divide both sides by 3,
3y/3=y 12/3=4
So Y-intercept is: 4
2. To find the X-intercept, replace y with zero.
2x + 3(0) = 12
2x=12
Divide both sides by 2
2x/2=x. 12/2= 6
So, x-intercept: 6
y-intercept: 4
Answer:
27
Step-by-step explanation
Sally = 4 x 3 = 12(left) + 15(spent) = 27
Lucy = 24(spent) + 3(left) = 27 (we dont multiply this part bc Lucy spent 9 more dollars than Sally, 3 x 3 is 9 which equals the difference)
