Explain how you can use absolute value to tell whether
the sum of two integers is positive or negative.

Answers

Answer 1

Answer:

Let the integers are p and q.

In case both integers are positive or negative, you add the numbers up and apply their sign to the sum.

Examples:

10 + 88 = 98-20 + (-15) = -35

In case one of the integers is negative and one positive.

p < 0, q > 0

Use absolute value in this case.

Subtract the numbers and apply the sign of the number with the greater absolute value.

Examples:

- 10 + 15 = |15 - 10| = |5| = 5- 15 + 10 = - |15 - 10| = - |5| = -5
Answer 2

Step-by-step explanation:

Let the numbers be x and y

If both are of same signs then

|x + y| = x + y

-|x + y| = -(x + y) = -x - y

If one is negative and one is positive

-|x + (-y)| = -|x - y| = -x + y

-|y + (-x)| = -|y - x| = -y + x

Why is speed not important in math ?

Answers

Because if you do a work to fast your teacher will attached new work
Speed is helpful, but it is more important to have a deep understanding on the concepts than to have a fast working ability without understanding.

Since everything in math is interconnected, the deeper your understanding of the foundational topics you learn, the more easily you’ll understand new concepts that build upon the foundations.

As a concept, speed or rates of change are a key topic in Calculus. So speed is also important that way too.

Which of the following fractions has the greatest value?

3/4

5/8

5/6

5/9

3/7

Answers

We can see that 420/504 is the largest value among the fractions. the fraction 5/6 has the greatest value.

To determine which fraction has the greatest value, we can compare the fractions by finding a common denominator and comparing the numerators.

Let's find a common denominator for all the fractions, which is the least common multiple (LCM) of the denominators.

The denominators are 4, 8, 6, 9, and 7.

The LCM of 4, 8, 6, 9, and 7 is 504.

Now, let's convert each fraction to have a denominator of 504:

3/4 = (3/4) * (126/126) = 378/504

5/8 = (5/8) * (63/63) = 315/504

5/6 = (5/6) * (84/84) = 420/504

5/9 = (5/9) * (56/56) = 280/504

3/7 = (3/7) * (72/72) = 216/504

Comparing the numerators, we can see that 420/504 is the largest value among the fractions.

Therefore, the fraction 5/6 has the greatest value.

The table below represents a function.

what could be the equation of the function?​

Answers

Answer: Choice C.  y = -1.5x

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

Explanation:

Pick any two rows from the table to form the (x,y) points. I'll pick the first two rows.

Use the slope formula to find the slope of the line through (-6,9) and (-4,6)

m = (y2-y1)/(x2-x1)

m = (6-9)/(-4-(-6))

m = (6-9)/(-4+6)

m = -3/2

m = -1.5

Of the four answer choices, only choice C has a slope of -1.5 so that must be the final answer. Note how the y intercept is b = 0 due to the point (0,0).

So y = -1.5x can be written as y = -1.5x+0; however, it's easier to go with the first option.

As a check, let's try something like x = 2

y = -1.5x

y = -1.5*2

y = -3

This verifies the second to last row of values. I'll let you check the other rows.

Answers

Answer and Step-by-step explanation:

1-6

a.

What you can do is plug in 6 and start by doing the first machine first, then the second. If this doesn't work, do the second machine, then the first machine.

The order that works is second machine, then first machine.

Second Machine:

y = [tex](6)^{2} -6[/tex] = 36 - 6 = 30

Plug into first machine now.

First Machine:

y = [tex]\sqrt{(30) - 5} = \sqrt{25} = 5[/tex]

We see that the result is 5.

b. If we were to do the order of second machine, then first machine, we will never get a negative result (or -5 for that matter), due to the fact that you can't algebraically square root a negative number.

However, if we were to do the order of first machine, second machine, we can get a negative number. To get -5, we plug in 6 for x in the first machine, getting an answer of 1. We plug this into the second machine, getting 1^2 - 6, which results in -5.

1-7. The absolute value of a value is the positive version of that value.

a. |54| = 54

b. [tex]-|-7\frac{3}{5}|[/tex] = [tex]-7\frac{3}{5}[/tex]

c. |3| - |-1| = 3 - 1 = 2

d. |2.2 - 5.13| = |-2.93| = 2.93

b. The amount of squares on each side of the figure increases by 1.

c. There would be 1 square, because we know that the pattern is there is 2 squares added to the next figure, 1 at each end. If we go back a figure, we take away 2 squares.

1-9.

a. -42 - 17 = -59

b. 8 - (-9) = 8 + 9 = 17

c. 8(-9) = -72

d. -42 ÷ (-7) = 6

e. -2(-3)(-4) = 6(-4) = 24

f. -18 - 7 = -25

g. [tex](-5)^{2}[/tex] = 25

h. [tex]-5^{2} = -(5)^2 = -(25)[/tex] = -25

i. [tex]\sqrt{49}[/tex] = 7

1-10.  x = 2 Plug 2 in for x, then solve.

a. y = 7 - 3(2) = 7 - 6 = 1

b. y = [tex](2)^2 -1[/tex] = 4 - 1 = 3

c. y = [tex]\frac{18}{2}[/tex] = 9
