Match the following definitions with their word
Answer:
A: law
B: The opposite of a number is its additive inverse. The sum of a number and its opposite is zero. (This is sometimes called the property of opposites ).
C: To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

y = -4x – 5
y = -2x + 10 solve using substitution show work please
Answer:
(- [tex]\frac{15}{2}[/tex], 25 )
Step-by-step explanation:
Given the 2 equations
y = - 4x - 5 → (1)
y = - 2x + 10 → (2)
Substitute y = - 2x + 10 into (1)
- 2x + 10 = - 4x - 5 ( add 4x to both sides )
2x + 10 = - 5 ( subtract 10 from both sides )
2x = - 15 ( divide both sides by 2 )
x = - [tex]\frac{15}{2}[/tex]
Substitute this value into either of the 2 equations and evaluate for y
Substituting into (2)
y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25
Solution is ( - [tex]\frac{15}{2}[/tex], 25 )
Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account. What is Mr. Smith's account balance now? *
Answer:
$ 263.42
Step-by-step explanation:
-275.78 + 539.20 = 263.42
The new balance in Mr. smith account will be $263.42.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account.
Assume that the new amount in his account will be [x]. Then -
[x] = 539.20 - 275.78
[x] = 263.42
Therefore, the new balance in Mr. smith account will be $263.42.

10. Write the fraction 9/50 as a decimal. If
necessary, round your answer to the nearest
hundredth.
A 0.28
© 0.5
B 0.18
D 0.09
Answer:
0.18
Step-by-step explanation:
9/50 is the same as 18/100, we know this because if we multiply both 9 and 50 by 2, it gives us 18/100. 18/100 can be turned into the decimal, 0.18, so your answer is 0.18

Renee used the values in the table to calculate simple interest.
Principal $750
Interest rate ?
Time 11 years
Interest $412.50
Which interest rate is missing from Renee’s table?
Question:
Which interest rate is missing from Renee’s table?
Answer:
Principal- $750
Interest Rate- $00.5
Time- 11 yrs. (Years)
Interest- $412.50
Explanation:
To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. ...
I = Interest amount paid in a specific time period (month, year etc.)
P = Principle amount (the money before interest)
t = Time period involved.
r = Interest rate in decimal.
Therefore we get an answer of $00.5

Answer:
A. x ≥ -3 and x < 2, or -3 ≤ x < 2
Step-by-step explanation:
Remember solid dot means include, open dot means not include.
x ≥ -3: this means x is greater and equal (includes) -3.
x < 2: this means x is less than 2 and does not include it.
Answer:
A
Step-by-step explanation:
So on the number line you see a closed circle at -3 and an open circle at 2.
Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.
So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].
The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].
To combine it together, it would get [tex]-3 \geq x < 2[/tex].
Since option A is [tex]x \geq -3[/tex] and [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.

y = 3x - 2
x - y = 4
Answer:
x=-1, y=-5
Step-by-step explanation:
y=3x-2 (1)
x-y=4 (2)
sub (1) into (2)
x-(3x-2)=4
x-3x+2=4
-2x=2
x=-1
sub x=-1 into (1)
y=3(-1)-2
=-3-2
y = -5
Therefore: x=-1, y=-5 :))
Answer:
x = -1, y = -5
Step-by-step explanation:
y = 3x - 2
x - y = 4
x - y = 4
x - (3x - 2) = 4
x - 3x + 2 = 4
-2x + 2 = 4
-2x = 2
x = -1
x - y = 4
-1 - y = 4
-y = 5
y = -5
Check:
x - y = 4
-1 - (-5) = 4
-1 + 5 = 4
4 = 4

A basketball team played five games. In those games, the team won by 7 points, lost by 3, won by 4, lost by 2, and won by 9. What was the mean difference in game scores over the five games?
Answer:
3
Step-by-step explanation:
7-3+4-2+9=15
15/5=3
The mean difference in the game scores over the five games is = 5
The points achieved by the various team players =
won by 7, lost by 3, won by 4,lost by 2,won by 9.To obtain the mean of the points achieved from the five
games the five scores are added together and divided by the number of games which is 5.
That is,
[tex] \frac{7 + 3 + 4 + 2 + 9}{5} [/tex]
[tex] \frac{25}{5} = 5[/tex]
Therefore the mean difference in game scores over the five games is = 5
