Mathematics
1 answer:
bogdanovich [222]4 years ago
5 0

Answer:

-2

Step-by-step explanation:

f(1) is the value of y when x = 1.

Thus, from the graph, we see that when x = 1 on the x-axis, on the y-axis, we have a corresponding y value of -2.

This means y = -2 when x = 1.

Therefore:

f(1) = -2

The description is very simple: Incorrectly solved.

More specifically at step 2 the subtraction of 3.8 should have been on both sides.

x+3.8=2.3 \\x+3.8-3.8=2.3-3.8 \\\boxed{x=-1.5}

Hope this helps.

Solve this system of equations:<br><br> 5x + y = 7<br> 20x + 2 = y
xz_007 [3.2K]

Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6
