Answer:
So you are given the function, f(x) = 3x - 4. You will plug in the value given and solve and write the answer down in the box.
f(x) = 3x - 4 ---> f(5), f(2), f(1), f(10), and f(-1) value given
f(5) = <u>3(5)</u> - 4
f(5) = <u>15 - 4</u>
f(5) = 11
f(2) = <u>3(2)</u> - 4
f(2) = <u>6 - 4</u>
f(2) = 2
f(1) = <u>3(1)</u> - 4
f(1) = <u>3 - 4</u>
f(1) = -1
f(10) = <u>3(10)</u> - 4
f(10) = <u>30 - 4</u>
f(10) = 26
f(-1) = <u>3(-1)</u> - 4
f(-1) = <u>-3 - 4</u>
f(-1) = -7

EQ. 1: x + y = 8
EQ. 2: 4x-y = 7
Rewrite EQ. 1 as EQ. 3: x = 8-y
Replace x in EQ.2 with EQ. 3:
4(8-y) - y = 7
Use the distributive property:
32 - 4y - y = 7
Combine like terms:
32 - 5y = 7
Subtract 32 from each side:
-5y = -25
Divide both sides by -5
y = -25 / -5
y = 5
Now replace y with 5 in EQ. 3 to solve for X:
x = 8-5
x = 3
The point of intersection is X = 3, Y = 5, which is written as (3,5)
Wouldn't it just be 300 kilometers per hour as the answer?
Answer:
<u>Hence final answer is B: Step 2.</u>
Step-by-step explanation:
Step 1: Find the total points needed to score in six games: 96x6=576
Justification:
Product of 96 and 6 is 576 which is same number found by Brenda. So step 1 is correct.
Step 2: Find the total points scored: 92+110+85+78=365
Justification:
Sum of total points scored by Brenda is 92+110+85+78= 461.
But she got different value 365.
Hence step 2 is wrong.
<u>Hence final answer is B: Step 2.</u>
