Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite this equation in slope-intercept form, y=mx+b, to find the pattern. She correctly rewrites the equation 7x+9y=14 in slope-intercept form as y=− 7/9x +14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?A. In slope-intercept form, the slope is 14/9. These values are C and A, but with the opposite sign, so the slope of the line from the equation in standard form is − C/A. B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B. C. In slope-intercept form, the slope is 14/9. These values are C and B, but with the opposite sign, so the slope of the line from the equation in standard form is − C/B. D. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − B/A.

A store sells 2 printers for every 5 computers. the store sells 40 computers. how many printers does the store sell?

Answers

Answer: 16 printers.

Step-by-step explanation:

We know that every 5 computers sold, the store sells 2 printers.

We know that the store sold 40 computers.

How many groups of 5 computers there are in 40 computers?

there are 40/5 = 8 groups of 5 computers.

So the sotre sold 8 times 2 printers = 8*2 printers = 16 printers

The store sold 16 printers because 40/5=8, and if they sold 2 printers for every five computers sold, they would have sold 16.

Evaluate [3(5 + 6) + 2] ÷ 7

Answers

[3(5 + 6) + 2] ÷ 7= 35/7

35/7=5

Answer:

Step-by-step explanation:

[3(5 + 6) + 2] ÷ 7

(5 + 6) = 11

[3(11) + 2] ÷ 7

3 x 11 = 33

[33 + 2] = 35

[35] ÷ 7 = 5

Thus the answer, 5

Given the equation 7(x + 2) = 2x − 1, solve for the variable. Explain each step and justify your process.Jeff solved a similar equation below. Is Jeff's solution correct? Explain why or why not.
3x − 2 = 5(x + 2)
3x − 2 = 5x + 10
8x = 8
x = 1

Answers

The original equation:    7(x + 2) = 2x − 1

Eliminate parentheses on the left: 7x + 14 = 2x - 1

Subtract 2x from each side:       5x + 14 = -1

Subtract 14 from each side: 5x    = -15

Divide each side by 5 : x = -3

==============================

Jeff thought he had solved a similar equation, but his solution is not correct.

Here are his steps, with my commentary:

3x − 2 = 5(x + 2) The original equation, to be solved.

3x − 2 = 5x + 10 Eliminated parentheses on the right, correctly.

8x = 8 Subtracted 5x from each side, incorrectly.
      Left side should be -2x, not 8x .

   Added 2 to each side, incorrectly.
   Right side should be 12, not 8.

x = 1   Divided each side by 8, correctly.
But the input from the previous step was garbage,
so the output from this one is garbage.

Jeff should have taken a moment to check his solution,
back in the original equation.

The original equation: 3x − 2 = 5(x + 2)

If x = 1, then 3(1) - 2 = 5 (1 + 2)

   3 - 2 = 5 (3)

   1 = 15 I'm afraid not.
   Poor Jeff.

Population since 2000 has been approximately linear. In 2006 the population was 1148 and in 2014 the population was 1348. What is the rate of population growth?

Answers

Answer:

2.03% Rate of Population Growth.

Step-by-step explanation:

According to the Question,

Given, In 2006 the population was 1148 and in 2014 the population was 1348.

2006⇒2014 (8 Years)

So, $1148 * (1+(x)/(100) )^(8) = 1348$

$(1+(x)/(100) ) = \sqrt[8]{1.1742}$

(1 + x/100) = 1.0202

x/100 = 0.020276

x = 2.03% Rate of Population Growth

How many micrometers long is one edge of a centimeter cube

Answers

Answer:

10000 micrometers.

Step-by-step explanation:

We have to convert the 1cm length of the edge of the cube to micrometers Remember the following conversion units:

$1* 10^(-6) m= 1 \mu m$ and $1* 10^(-2) m= 1 cm$ denoting m for meters, cm for centimeters and μm or micrometers. In particular, dividing on both sides of the first equation we get the identity $1=(1\mu m)/(1* 10^(-6) m)$

Combine the previous information to get:

$1 cm=1* 10^(-2) m= (1* 10^(-2) m) \cdot (1)= (1* 10^(-2) m)(1\mu m)/(1* 10^(-6) m)=(10^(-2))/(10^(-6))\mu m=10^4 \mu m=10000 \mu m$

Note how we "cancelled" the m symbolically as if it was a variable. This is one of the methods to convert units, and the fractions involved are known as conversion factors.

10000 micrometers if it is one cenimeter per side
