Jenna was 4 4/6 feet tall last year. This year she is 5 2/6 feet tall. How many feet did Jenna grow in the past year

Answers

You want to subtract the heights. 5 2/6-4 4/6=5 1/3-4 2/3=2/3.

You could turn the mixed fractions into improper fractions so 4 4/6 would become 28/6 and 5 2/6 would become 32/6. Then you can subtract 32/6 by 28/6 which would be 4/6 simplified into 2/3

What is the slope of this line

Answers

Answer:

-8/5 is the slope.

Step-by-step explanation:

To find slope, it's the change in y over the change in x. Or rise over run.

That would be 8/5.

And this line would be negative because it is going from left to right.

So your final answer would be -8/5 as your slope.

What is the effect on the graph of the linear parent function, f(x) = x, when f(x) is replaced by f(x + 5)?A) The graph of the line becomes steeper.
B) The graph of the line shifts horizontally right 5 units.
C) The graph of the line shifts vertically down 5 units.
D) The graph of the line shifts horizontally left 5 units.

Answers

Answer:

D) The graph of the line shifts horizontally left 5 units.

Adding a number, n, inside of the parenthesis with x would move the parent function n units to the left.

Here are the rules:
F(x + a) shifts a units left.
F(x - a) shifts a units right.

You can see this by taking for example f(x) = x^2 then f(x+5) = (x+5)^2, if you graph y=x^2 and y=(x+5)^2, you will see it is shifted 5 units to the right.

An equation and the steps to solve it are shown below:2x − one over four (12x + 4) = 3 Step 1: 2x + 3x + 1 = 3 Step 2: 5x + 1 = 3 Step 3: 5x + 1 − 1 = 3 − 1 Step 4: 5x = 2 In which step was the error made and why? Step 1, because incorrect signs have been used Step 2, because the terms have been added incorrectly Step 3, because a number has been subtracted from both sides of the equation No error was made
