Answer:
[tex]x = - 3[/tex]
[tex]y = 1[/tex]
Step-by-step explanation:
Write the system
[tex]3x - y = - 10[/tex]
[tex]x + y = - 2[/tex]
Solve by Elimination.
multiply the second equation by -3.
[tex]3x - y = - 10[/tex]
[tex] -3x - 3y = 6[/tex]
Add the Equations.
[tex] - 4y = - 4[/tex]
[tex]y = 1[/tex]
Plug this back in one of the equations.
[tex]x + 1 = - 2[/tex]
[tex]x = - 3[/tex]
Answer:
x = -3
y = 1
Step-by-step explanation:
3x - y = -10
x + y = - 2
x + y = - 2
x = -y - 2
replacing in other equation
3(-y - 2) - y = -10
-3y - 6 - y = - 10
rearranging the equation
-3y - y = = -10 + 6
-4y = -4
y = 1
putting this value in first eqn we get
x - y = -2
x - (1) = -2
x = -2-1
x = -3

The area of a rectangular parking lot is 6364 m². If the width of the parking lot is 74 m, what is its length?
Length of the parking lot:
Answer:
86m
Step-by-step explanation:
Area of rectangle = length x breadth
Area of rectangle = 6364m²
Breadth of rectangle = 74m
6364 = length x 74
length x 74 = 6364
length = 6364/74 = 86m

Hey there! I'm happy to help!
When evaluating the value of an expression, we need to follow the order of operations which is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction).
First, we will evaluate the exponent. 3² is 3×3 which is 9.
[tex]\frac{9+2*8}{16-11}[/tex]
Now we have to do multiplication. Since the multiplication sign is between the 2 and the 8, that is what we multiply.
[tex]\frac{9+16}{16-11}[/tex]
Then we will do our addition and subtraction.
[tex]\frac{25}{5}[/tex]
Since all fractions are just division problems, we can do 25÷5.
25÷5=5
So, the value of this expression is 5.

Answer:
60 and - 12
Step-by-step explanation:
Substitute x = - 4 into f(x) , that is
f(- 4) = 3(- 4)² - 3(- 4) = 3(16) + 12 = 48 + 12 = 60
Substitute x = 4 into g(x)
g(4) = - 4(4) + 4 = - 16 + 4 = - 12

Answer:
a) 7x words
b) 1000/x days
c) 15000 + 10x words
Step-by-step explanation:
The best way to do this would be to plug in real numbers to see how each situation would play out. For example, for part a, let's say he learns 20 new words each day. One week has seven days, so that would be 20 x 7, which is 140 words. You multiply the # of days by the # of words, which is x.
For part b, if he tried to reach 1000 new words by doing 20 new words a day, you would find how long that would take by doing 1000 / 20, which would give you 500 days. You divide the # of new words he's trying to reach by the # of words a day.
For part c, he already has a set # of new words that he's learned, and now he's just continuing the progress, so you start out with 15000, then add that to 10 new words a day multiplied by # of days (x).

Which of the following values are solutions to the inequality —8 – 4x > 1?
1. -10
2.-1
3. 6
Answer:
option 1. -10
Step-by-step explanation:
—8 – 4x > 1
adding 8 on both sides,we get
-8-4x+8>1+8
-4x>9
by dividing both sides by -4, we get
-4x/-4<9/-4
x<-2.25
Hence, from the above option only -10 is smaller than -2.25. Therefore your answer is option 1.

what is the answer for baby eleaphants
Answer:
3?
Step-by-step explanation:
im not sure tho
Let A = 0, 1 , B = 2, 3, 4 and C = 3, 5 verity that A x (BUC) = (AXB) U (AXC)
A = {0, 1}
B = {2, 3, 4}
C = {3, 5}
Then we have
A × (B U C)
= {0, 1} × {2, 3, 4, 5}
= {{0, 2}, {0, 3}, {0, 4}, {0, 5}, {1, 2}, {1, 3}, {1, 4}, {1, 5}}
and
(A × B) U (A × C)
= {{0, 2}, {0, 3}, {0, 4}, {1, 2}, {1, 3}, {1, 4}} U {{0, 3}, {0, 5}, {1, 3}, {1, 5}}
(underlined pairs are duplicates and common to both A × B and A × C)
= {{0, 2}, {0, 3}, {0, 4}, {0, 5}, {1, 2}, {1, 3}, {1, 4}, {1, 5}}
and these two sets are clearly identical.

Step-by-step explanation:
Barbara requires 2 gallons of paint to cover an area of 800 square feet. Identify the graph for the relationship from quantity to the area covered, and the parent function that best describes it. Then use the graph to estimate how many gallons of paint Barbara requires to paint an area of 2,400 square feet.
Answer:
6
Step-by-step explanation:
x = area to be painted
y = gallons of paint needed
we know already one point of that function/graph :
x = 800
y = 2
so, for a simple relationship between the 2 variables we can assume
y = ax
2 = a×800
a = 2/800 = 1/400
so, we get
y = (1/400) x
for 2400 ft²
y = 1/400 × 2400 = 1/4 × 24 = 24/4 = 6
she needs 6 gallons of paint for 2400 ft².
6 gallons of paint are required to cover 2400 ft² area.
Graph options aren't given ; however, we could still obtain the required solution using the information given :
2 gallons covers 800 ft²
Let the number of gallons to cover 2400 feets = x
Using cross multiplication :
2 gallons = 800 feets
x gallons = 2400 feets
Cross multiply :
800 × x = 2400 × 2
800x = 4800
Divide both sides by 800
x = 4800 / 8
x = 6
Hence, 6 gallons of paint are required to cover 2400 ft².

using the variable n write an algebraic expression for a number increased by 6
The answer you are looking for is simply just n+6.
Solution/Explanation:
If you use the variable "n" to write an algebraic expression, for a number increased by 6, you must write it like this:
n+6.
And, also, increase obviously means the same thing as adding.
So, therefore, "n" stands for the number in this algebraic expression, and if you add 6 to that number "n," it must be n+6.
So, therefore, the final answer is n+6.
I hope that this has helped you. Enjoy your day, and take care!
