the equivalent of two integer is not always integer . true or false?
please be fast i don't understand it.
Answer:
Yes it is true. Sum of two integers is always an integer
Step-by-step explanation:
Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

1) Stephanie is running down the street at 10 m/s. She sees a double-tall latte on the road ahead of her and starts sprinting. After 5 seconds have passed, Stephanie is running 15 m/s. Assuming she does not change directions, what was Stephanie's acceleration? Hints Vi = 10 m/s Ve = 15 m/s t = 5 seconds Use 'm/s/s' or 'm/s2' as the correct label.
solve the inequality, SHOW WORK, please help I'll give brainliest
1. x≤5 Work: 2x+9≤19 move the constant to the right then its 2x≤19-9, then subtract the numbers and it would be 2x≤10, then divide both sides of the inequality by 2 which gives you the final answer of x≤5
2. x≥19 Work: x-7≥12 move the constant to the right then its x≥12+7, then add the numbers and get your final answer of x≥19
3. x≤4 Work: Divide both sides of the inequality by -3 and flip the inequality sign and that gives you -3÷(-3)≤-12÷(-3) and divide that which gives you x≤4
4. x<-3 Work: move the constant to the right which gives you -5x>16-1, then subtract to get -5x>15 and divide both sides of the inequality by -5 and flip the inequality sign to get x<-3

The kinetic energy of an object is given by the formula E = mv2. If m is in kg and v is in m/s,
then E is in joules. What is the kinetic energy of an electron (mass = 9.1 x 10-31kg) travelling at a
fifth of the speed of light (speed of light, c = 3 x 108m/s)?
Answer:
9.553×10^-26
Step-by-step explanation:
m= 9.1 ×10 ^-31
v = 3 × 108
= ( 9 .1 × 10 ^- 31) × ( 3 × 108 ) ^2
= 9 .552816 × 10 ^ -26
approximately
9.553×10 ^26

The equation of the proportional relationship represented by the table and the graph is: y = 2x.
What is a Proportional Relationship?If m is the slope or unit rate, a proportional relationship between two variables, x and y, can be represented with an equation as, y = mx.
Let's find the equation that represents the relationship represented by the graph and the table. Let's use the graph.
m = y/x
Using the point, (2, 4),
m = 4/2 = 2
Substitute m = 2 into y = mx
y = 2x
Therefore, the equation of the proportional relationship represented by the table and the graph is: y = 2x.

What kind of Slope goes up and to the right? What kind of Slope goes down to the right? What kind of Slope is flat?
Answer:
A positive slope goes up and to the right
A negative slope goes down and to the right
A slope of zero creates a flat line
Step-by-step explanation:
A positive slope goes up and to the right, because that means the graph is increasing.
A negative slope goes down and to the right, because that means the graph is decreasing.
A slope of zero creates a flat line, such as a horizontal line that never increases in the y value.

students in her class could not give the correct answer.
What is the number of students who answered correctly?
Answer:
23
Step-by-step explanation:
find 10% = 4
quadruple it = 16
half 10% = 2
half it again = 1
2.5% = 1
40% = 16
1 + 16 = 17
take 17 off of 40 = 23

A volleyball camp chargers $150 per camper for 10 campers. When a team brings 15 campers, the rate is reduced to $125 per camper. What is the rate of change in cost per camper ?
Answer: $6.67
Step-by-step explanation:
A volleyball camp chargers $150 per camper for 10 campers. The cost for each camper will be:
= $150/10
= $15
When a team brings 15 campers, the rate is reduced to $125 per camper. The cost for each camper will be:
= $125/15
= $8.33
The rate of change in cost per camper will be:
= $15 - $8.33
= $6.67
