Answer:
x=-8, y= -43
Step-by-step explanation:
y = 6x + 5
y= 4x - 11
Since both equations are equal to y, we can set them equal to each other
6x + 5= 4x - 11
Subtract 4x from each side
6x-4x+5 = 4x-4x-11
2x+5 = -11
Subtract 5 from each side
2x+5-5 = -11-5
2x = -16
Divide each side by 2
2x/2 = -16/2
x = -8
Now we need to find y
y = 6x+5
y = 6(-8) +5
-48+5
-43
Answer:
x = -8 y = -43
Step-by-step explanation:
y = 6x + 5
y= 4x - 11
6x + 5 = 4x - 11
2x = -16
x = -8
y = 4(-8) - 11
y = -32 - 11
y = -43
What strategy you used to solve Problem 3.
Answer: where is it??
Step-by-step explanation:
a restaurant has 25 square tables. one person can fit on each side of a table. how many people can be seated if all the tables are placed end to end in a line?
Answer:
52 people
Step-by-step explanation:
If you place 25 square tables in a line, the 23 tables in the middle can only seat 2 people each since the other two sides are touching two other tables. The end two tables can seat 3 people since only one of their sides is touching another table.
So multiply 23 by 2 to find out how many people are sitting in the middle and then add 6 people for the two tables on the end.
23(2) + 3(2) = 52 people
Seven different models cars, from which there are three blue and four red, are to be parked in a row. Find how many different arrangements there are if the first, the last, and the car in the middle of the queue should be blue.
Answer ASAP for brainliest answer!
Answer:144 ways
Step-by-step explanation:
Given
There are 7 different models cars
out of which three are blue and 4 are red
If the first middle and last car in Queue is blue car therefore the position of blue cars is fixed
But these 3 cars can be arranged in 3! ways
Remaining 4 cars can be arranged in remaining 4 spots in 4! ways
Therefore total no of ways are
[tex]=3!\times 4![/tex]
[tex]=6\times 24=144\ ways[/tex]
Lucia speed walks 3 kilometers in of an hour. At 2/3 that rate, how many meters does she speed walk per minute?
Answer:
2000 meters
Step-by-step explanation:
The first step in this problem is to find 2/3 of 3 kilometers per hour.
2/3 * 3/1 = 6/3. This can be simplified to 2 kilometers per hour.
Now, find the rate of meters per minute. To do so, multiply 2 by 1000.
2 * 1000 = 2000
Therefore, at 2/3 of Lucia's rate, she walks 2000 meters per minute.
Answer:
The answer is 75 meters per minute.
Step-by-step explanation:
Ok I been seeing people say 2000 meter which is WRONG. 1 kilo= 1,000 meters
2/3 of an hour= 40 minutes
3,000 meters/40mins= 75 meters per minute

Solve x + x + 2 + 2x = -2.
1
-1
0
-2
Answer:
[tex]x=-1[/tex]
Step-by-step explanation:
[tex]x + x + 2 + 2x = -2[/tex]
First, we need to collect like terms:
[tex]4x+2=-2\\4x=-4[/tex]
Then we divide both sides by 4:
[tex]\frac{4x}{4}=\frac{-4}{4}\\x=-1[/tex]
The answer is x = -1.
To solve this equation, you must collect like-terms by adding together x terms and numbers, and then rearrange to get x on one side and numbers on the other:
x + x + 2 + 2x = -2
4x + 2 = -2
- 2
4x = -4
÷ 4
x = -1
I hope this helps! Let me know if you have any questions :)
Find the slope of the equation: x=3 answers: 1) zero 2) -1/3 3) 3 4) undefined
Answer:
4) undefined
Step-by-step explanation:
When graphing x=3, you'll find that it is a vertical line, that intersects the x axis at 3.
Slope is rise over run.
Our line is rising infinitely for every 0 runs.
So it would pretty much be infinitely/0
Since you can't divide a number by 0, we consider the slope of a vertical line, undefined.

Find the constant of proportionality (r) in the equation y=rx
Answer:
The constant of proportionality is 75/58 or 1.29
Step-by-step explanation:
Given
The table above
Required
Find the constant of proportionality
The question has an incomplete table but it can still be solved because x and y are proportional.
Given that
y = rx
Make r the subject of formula
Divide through by x
y/x = rx
y/x = r
r = y/x
When y = 7.5, x = 5.8
Substitute these values
r = y/x becomes
r = 7.5/5.8
Multiply denominator and numerator by 10
r = (7.5 * 10)/(5.8 * 10)
r = 75/58
In this case, it's best to leave the answer in fraction.
However, it can be solved further.
r = 75/58
r = 1.29 (Approximated)
Hence, the constant of proportionality is 75/58 or 1.29
Answer:
the correct answer is 1

Which value of x makes this sentence true?
1/2 + x=10/11
A:9/22
B:11/13
C:8/9
D:13/22
Answer:
9/22
Step-by-step explanation:
1/2 + x=10/11
Subtract 1/2 from each side
1/2-1/2 + x=10/11-1/2
x = 10/11 -1/2
Getting a common denominator of 22
x = 10/11*2/2 -1/2 *11/11
x = 20/22 - 11/22
x = 9/22
Answer:
x=9/22
Step-by-step explanation:
u have to subtract 1/2 on both sides, so u can get X by itself
1/2-1/2+x=10/11-1/2
get the common denominator for 10/11 and 1/2
10/11 times 2/2=20/22
1/2 times 11/11=11/22
20/22-11/22= 9/22
x=9/22
ANSWER CHECK
substitute the variable X for 1/22
1/2+9/22=10/11
common denominator
1/2 times 11/11=11/22
11/22+9/22= 20/22 or 10/11

Starting at time t = 0, the altitude of one helicopter is given by A1 = 600 + 150t, and the altitude of a second helicopter is given by A2 = 1250 + 50t. Which equation represents the difference of their altitudes A at time t?
Answer:
The equation for difference in altitude of the two helicopters is A = 650 - 100t
Step-by-step explanation:
Given;
The altitude of one helicopter is, A1 = 600 + 150t
The altitude of a second helicopter is, A2 = 1250 + 50t
Their difference in altitude, A at time t, is calculated as
A₂ - A₁ = A = (1250 + 50t) - (600 + 150t)
A₂ - A₁ = A = 1250 + 50t - 600 -150t
A₂ - A₁ = A = 1250 - 600 + 50t - 150t
A₂ - A₁ = A = 650 - 100t
Therefore, the equation for difference in altitude of the two helicopters is A = 650 - 100t
