Jacob is asked to solve the follow problem: "Kayla is 9 years older than twice Hannah’s age. If the difference in their ages is 16, how old is Kayla? How old is Hannah?" Jacob finds Hannah’s age to be 16 years. Is he correct? Explain

Answers

Answer 1

Answer:

Step-by-step explanation:

k = 2h+9

h+16=k

h+16=2h+9

-h = -7

h = 7

hannah is 7 and kayla is 23

jacob is wrong because if u do 16*2+7 it’s 39 and 39-16 does not equal 16

Can you share a strategy for error analysis? Of multiplying.

Answers

Yes ! Because it’s that because it’s it
Not sure if this is right, but your teacher could give you a multiplication problem and she solves it. The twist: She makes an error within the work she did to solve it & therefore got the wrong answer. It’s now your turn to figure out where the error was and how to fix it to get the correct answer.

What is the equation of a line?

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Function 1:

With coordinates (0, -2) and (2, 0)

Now, m=(0+2)/(2-0)

m=1

Substitute m=1 and (x, y)=(0, -2) in y=mx+c, we get

-2=c

Substitute m=1 and c=-2 in y=mx+c, we get

y=x-2

Function 2:

With coordinates (-2, 0) and (0, 4)

Here, m=(4-0)/(0+2)

m=2

Substitute m=2 and (x, y)=(-2, 0) in y=mx+c, we get

0=-4+c

c=4

Substitute m=2 and c=4 in y=mx+c, we get

y=2x+4

Therefore, options B and D are the correct answers.

A car salesperson sells a used car for ​$ and earns ​% of the sale price as commission. How many dollars does the salesperson earn in​ commission?

Answers

You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.

If the salesman sells a car for $a and gets b% of the sale price as commission, then what you need to do is divide the a by 100, then multiply it by b to find out b% of a. This will be the commission that he will earn.

a / 100 x b = commission earned in $

Edit

You've now supplied me with the $ and %, let me explain it again.

To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.

8,100 / 100 = 81

81 x 9 = $729 commission earned.

Answers

Answer:

The slope is positive, because the line is going up

The equations is.....y = 2/3x - 2

To find slope we can make a table

x      y

6     2

3     0

From 2 to 0, we subtract 2 ( y section)

From 6 to 3, we subtract 3 (x section)

Now we do y/x

so...y/x = -2/-3 = 2/3 (since 2 negatives equal a positive)

Slope = 2/3

And for the y-intercept, I used the graph to help me out, and to find it, you need to see where the line intersects the y-axis which is at -2.

Hope this helped!

Potatoes: $1.23
Broccoli: $3.10
Pears: $0.98

Answer:

Potatoes = $0.56 per pound

Broccoli = $2.90 per pound

Pears = $0.98 per pound

Step-by-step explanation:

Potatoes

To find the price per pound of the potatoes, we will need to divide $2.52 by 4.5 to find out how much one pound costs:

$2.52 / 4.5 = $0.56

The formula is the same for all of the other items.

Broccoli

$7.25 / 2.5 = $2.90

Pears

$2.45 / 2.5 = $0.98

Answers

Answer:

B.

Step-by-step explanation:

First, (3/2) is greater than 1, which therefore eliminates A and D.

Second, you must determine if the triangle gets larger or smaller. Lets suppose that X = 2 and Y = 3. If we were to multiply both of these values by (3/2), our points would change to X = 3 and Y = 4.5

Since there was an increase, this means that the triangle was larger.

This leaves B as the answer.

Remember: Any scale value greater than 1 is an enlargement, as proven by the hypothetical.

HELP WILL GRIVE BRAIN 100 POINTS PLEASE ANSWER ALL 5

Answers

Answer:

1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3

2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3

3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12

4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5

5. To put x by itself, you subtract 1 by 4, giving you x<-3
