What are two integers whose sum is -20

1 answer:

5 0

Hey! Hope that I can help!

To do this, all we need to do is find 2 integers that can add up to be -20, or $x$ + [tex]x[tex] = -20. So, to get 2 integers that can add up to a specific value, an easy thing to do is to figure out what could add up to -20. One pair of numbers that would work here is -5 and -15.

If this helped, please mark this answer the brainliest. Thanks!

At a family reunion, a family friend brings 20 pounds of ice and 30 cups. Which expression shows the greatest common factor, usi

Eddi Din [679]

The expression for the greatest common factor of 20 and 30 using the distributive property is 10(2 + 3)

Pounds of ice = 20

Number of cups = 30

The relation for the distributive property :

a × (b + c)

Expand ;

a × (b + c) = (a × b) + (a × c) = ab + ac

Finding the greatest common factor of 20 and 30 ;

20 = 2 × 10

30 = 3 × 10

(2 × 10) + (3 × 10)

According to the distributive property

(2 × 10) + (3 × 10) = 10(2 + 3)

Therefore, the expression for the greatest common factor is 10(2 + 3)

I need help with these three problems.... please help me????

viva [34]

12. Answer: 2130

Step-by-step explanation:

T = -0.01y + 10.6

9.2 = -0.01y + 10.6

-10.6 -10.6

-1.4 = -0.01y

÷-0.01 ÷-0.01

140 = y

"y" represents the number of years after 1990

1990 + 140

= 2130

13. Answer: -0.0036° per foot

Step-by-step explanation:

Since the relationship is linear, then we can set up the values as x, y coordinates and use the slope formula to find the rate of degrees over feet.

(6562, 63) and (16405, 28)

rate = $\frac{28 - 63}{16405-6562}$

= $\frac{-35}{9843}$

= $\frac{-0.0036}{1}$

**************************************************************

14. Answer: $0.28 per kWh

Step-by-step explanation:

Same reason as #13

(200, 55) and (500, 140)

rate = $\frac{140-55}{500-200}$

= $\frac{85}{300}$

= $\frac{0.28}{1}$

Which linear inequality is represented by the graph

Arlecino [84]

Answer: $\Large\boxed{First~choice.~y\leq \frac{1}{2}x+2 }$

Step-by-step explanation:

<h2>Determine the equation form of the inequality</h2>

Given function form

Point-Slope form : y = mx + b

m = slope
b = y-intercept

Given the information from the graph

Since the graph crosses (0, 2), b = 2

Find the slope

Choose any two points from the graph

(x₁, y₁) = (0, 2)

(x₂, y₂) = (2, 3)

Slope = (y₂ - y₁) / (x₂ - x₁)

Slope = (3 - 2) / (2 - 0)

Slope = 1 / 2

m = 1 / 2

Therefore, the equation form of the inequality is y = (1/2)x + 2

<h2>Determine whether it is ≤ or ≥</h2>

Since it is a solid line, the values on the line are also included. Thus, it must be either greater than or equal to, or less than or equal to.

The shaded region is below the solid line, therefore, it is ≤

Therefore, the inequality is $\Large\boxed{y\leq \frac{1}{2}x+2 }$

To double-check the sign, we can substitute (0, 0) into the inequality to see whether it is true.

y ≤ (1/2) x + 2

0 ≤ (1/2) 0 + 2

0 ≤ 2 TRUE

Hope this helps!! :)

Work out the value of 10^2-4^3 .give your answer as a power of 6

Fittoniya [83]

Answer:

Answer: 6^2

Step-by-step explanation:

Givens

Express the integers raised to a power as integers.
10^2 = 100
4^3 = 64

Solution

Subtract 64 (which is 4^3) from 100. See if what is left is a power of 6
100 - 64 = 36 Yes the remainder is 36
36 = 6*6 = 6^2
