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

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
I hope this helps :)
Over the course of 4 months, Spiffy the dog lost 36 pounds. What integer represents his loss per month?
Answer:
-9 pounds / month
Step-by-step explanation:
A loss of 36 pounds is a negative number
-36
Divide by the number of months
-36 pounds / 4 months
-9 pounds / month
Divide total loss by number of months:
36 pounds / 4 months = 9 pounds per month.
Because it lost weight the integer would be negative 9 (-9)
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

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

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 )

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.
