Consider the expression 2 6 3··52 1 27 4··152 1 2 1··5. a. Estimate the value of the expression. Show your work.

Answer: y = 1/2x + 1

Step-by-step explanation:

The formula is y = mx + b where mx is the slope (rate of change) and b is the initial value (y-int), here your rate of change is 1/2 so mx= 1/2x and your y-int(starting value) is 1 so b = 1

therefore:

y = 1/2x + 1

Step-by-step explanation:

Answer:

D. 0.27. 1/3. 1 1/4. 1.35

Step-by-step explanation:

1/3 = 0.3

1 1/4 = 1.25

1. 0.27

2. 0.3 or 1/3

3. 1.25 or 1 1/4

4. 1.35

Answer: 12

Step-by-step explanation:

x = 0 when it would start so

y= 3(0) + 12

y = 12

Basically, the initial value.

Answer: the rate of change is 1/2

Step-by-step explanation:

The formula for slope is y2 - y1/ x2 - x1

I picked points (2,2) (x1 & y1) and (6,4) (x2 & y2)

4 - 2 = 2

6 - 2 = 4

2/4 is the rate of change, and 1/2 is 2/4 simplified

Answer: nhi do you ave any pictures that i coulkd see to help sovle this problem

Step-by-step explanation:

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Answer: 1/2, 0.51, 11/20

Step-by-step explanation:

Use 100 as a common denominator so you can compare all the numbers in like terms:

1/2 = 50/100

0.51 = 51/100

11/20 = 55/100

Answer:

[tex]\frac{1}{2} 0.51, \frac{11}{20}[/tex]

Step-by-step explanation:

First, you want to change the decimal into a fraction.  0.51= [tex]\frac{51}{100}[/tex]

Then, find the common denominator.  In my example, I used 100.  Find the equivalent fraction for the fractions with 100 as their denominator

[tex]\frac{11}{20} = \frac{55}{100} \\\\\ \frac{1}{2} = \frac{50}{100}[/tex]

Next, line them up in order of their numerators

[tex]\frac{50}{100} \frac{51}{100} \frac{55}{100}[/tex]

Finally, match the new fraction with their reduced fraction or decimal:

[tex]\frac{1}{2} = \frac{50}{100} \\\\0.51 = \frac{51}{100} \\\\\frac{11}{20} = \frac{55}{100}[/tex]

13:

Going from 40 to 25 is a decrease of 15.  Comparing that 15 to the starting amount of 40, we have a decrease of [tex]\dfrac{15}{40}[/tex] or 0.375 or 37.5%.  Since you need to round to the nearest whole number, that'd be a decrease of about 38%.

14.

Going from 120 to 140 is an increase of 20.  Comparing that 20 to the starting amount of 120, we have an increase of [tex]\dfrac{20}{120}[/tex] or about 0.1667 or about 16.67%.  Since you need to round to the nearest whole number, that'd be an increase of about 17%.

You always divide the amount of change by the starting value, not the ending value.

Answer:

It has zero solutions since its a contradiction

Answer:

No Solution

Step-by-step explanation:

1/2x+6=1/4(2x-24)

Distribute numbers in parenthesis

1/2x+6=1/2x-6

When you try to move both of the x's to the same side, you are left with 0x

6≠-6

Therefore no solution

Answer:

$20.57

Step-by-step explanation:

First you have to find how many hours he/she works per week (38) and how many weeks he/she works a year (50) and how much he/she makes a year (39,095)

Now in order to find this we have two ways I will use the simpler way so it makes it easier to write and tell to you're teacher :)

First you multiply 50 and 38

50 × 38 = 1900

Since you know how much he/she makes a year you just divide.

39,095 ÷ 1900 = 20.57

So that makes your answer 20.57, Hope this helps and if it did and if I deserve it pls give brainlyest thank you :)

Answer:

-3.35 > -3.37

Step-by-step explanation:

-3 7/20 = -3.35

-3.35 > -3.37

Answer:

1. 2x-1=21/3

2x-1=7

2x=7+1

2x=8

X=8/2

X=4

2. 100/8=4t-5

12.5 =4t-5

12.5+5 =4t

16.5 =4t

16.5/4 =t

4.1=t

The ratio (or raicios) are 2:4, 4:8, 8,16, so on and so on.

The question states, vanilla cake calls for 2 cups of sugar for every 4 eggs. So basically you would add 2 every time you count to 4. Ex: 4 x 3 = 2 x 3,

4 x 6 = 2 x 6. Whatever happens to one side, has to happen to the other.
