See below for answers and explanations
Step-by-step explanation:
<u>Part A:</u>
f(x) = -x² + 4x - 10
f(2) = -(2)² + 4(2) - 10
f(2) = -4 + 8 - 10
f(2) = 4 - 10
f(2) = -6
<u>Part B:</u>
g(x) = 5x + 1
g(6) = 5(6) + 1
g(6) = 30 + 1
g(6) = 31
<u>Part C:</u>
f(x) = -x² + 4x - 10
f(-1) = -(-1)² + 4(-1) - 10
f(-1) = -1 - 4 - 10
f(-1) = -5 - 10
f(-1) = -15
<u>Part D:</u>
g(x) = 5x + 1
16 = 5x + 1
15 = 5x
3 = x
x = 3
Answer:
0.8
Step-by-step explanation:
0.8x250=200, which is the closest tenth of a decimal.
A is the correct answer.
This is because if you multiply 0.25 by 4, that would equal 1. Now, multiply 12 by 4 as well and you'll get 48. So the scale is 1:48.
Answer:
x > 1/4
Step-by-step explanation:
Answer:
1 hotdog is $3.5.
1 drink is $2.
Step-by-step explanation:
18.50= 3x+4y(times 5)
25.50=5x+4y(times -3)
92.5=15x+20x
-76.5=-15x+-12y
16=-8y
2=y
18.50=3x+4(2)
10.50=3x+8
10.50=3x
3.5=x
