Answer:
y=7x+5
Step-by-step explanation:
some of the other choices may be parellel to y=7x-3 but they don't have 5 as the y intercept
We could find the error first, but if we solve the equation, we can compare our answers to find the error. So,
7x + 12 + 3x = 8
10x + 12 = 8
10x = -4
x = -4/10
x = -2/5.
When we compare the two, we see that our second line is vastly different, and we can easily isolate the mistake, finding that it occurs when they disregard the variable in the 3x term and subtract 8 by 3 rather than combining the terms 3x and 7x together.
Answer:
Step-by-step explanation:
This is actually a very important question and it is very subtle. Let's just take an ordinary segment.
Suppose we have a segment that is this long
=========o=========
The segment up to the o is nine equal signs long.
The segment after the o is also nine equal signs long.
Here's the crunch. Since they are equal, the ratio is 1 to 1. The segment is divided in half.
Now take the second half of the question.
======o============
The left side of the o is 6 equal signs long.
The right side of the o is 12 equal signs long.
The ratio is 1:2. There are still 18 equal signs but now they are divided as 6/12 which is not the same thing as 9/9
Very interesting question.
Answer:
Step-by-step explanation:
Lets get the equation for the graphed function
<u>Using two points: </u>
Y-intercept is known, it is -6 as per the first point
<u>Slope is:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (0+6)/(3-0) = 6/3= 2
<u>So the function f is:</u>
<u>g(x) is going to be</u>
- g(x) = -1/2f(x + 2) = -1/2 (2(x+2) - 6) = -1/2(2x + 4 - 6) = -1/2(2x - 2) = - x + 1
