A system of two linear equations has infinitely many solutions. One equation is x - 2y=6. Select the equation that
would make this system have infinitely many solutions.
A .x + 2y = 6
B .x-2y = 4
C . 2y-x= -6
D .- 2y + x=4
Answer:
C . 2y-x= -6
Step-by-step explanation:
A system of linear equations can have no solution, a unique solution or infinitely many solution.
We say two linear equations has infinitely many solutions when the result is true.
To determine if a system has infinitely many solutions, the coefficient of their respective variables (x and y) would be equal. Also the constant of both equations would be equal.
Given that x - 2y = 6
The coefficient of x is 1, coefficient of y is -2 and constant is 6. The equation with the same attributes is:
C . 2y-x= -6
2y - x = -6
multiply through by -1
x - 2y = 6
It is same as the above
Adding both x - 2y = 6 and 2y-x= -6 gives 0 = 0
What is 1/2 divided by 1/3
Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]
The reciprocal of [tex]\frac{1}{3}[/tex] is 3, so finding the reciprocal will replace the division sign with a multiplication sign.
= [tex]\frac{1}{2}[/tex] x 3
= [tex]\frac{3}{2}[/tex] or 1[tex]\frac{1}{2}[/tex] or 1.5

a. 10 days b. 11 ¼ days c. 20 days d. 24 days
PLEASE HELP I SUCK AT THESE
9514 1404 393
Answer:
c. 20 days
Step-by-step explanation:
Divide the total available rice by the rate of its use:
time = quantity/(rate of use)
(15 lb)/(0.75 lb/day) = (15/0.75) days = 20 days

Slope=
Slope = change in Y over change in X:
Slope = (1 - 8) / (5-9)
Slope = -7/-4
Slope = 7/4
Answer:
The slope is [tex] \frac{7}{4} [/tex].
.
Step-by-step explanation:
Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆And now we just plug in!
[tex]m = \frac{1 - 8}{5 - 9} = \frac{ - 7}{ - 4} = \frac{7}{4} [/tex]

A water tank is 5/6 full. When 30 litres of water are removed from the tank, the tank is 4/5 full. How much water does the tank hold when full?
will give brainliest please help
Answer:
900 L
Step-by-step explanation:
Let x be the number of litres when the tank is full.
Then 5/6 x - 30 = 4/5 x
Solve this by converting to /30:
25/30 x - 30 = 24/30 x
1/30 x = 30
x = 30*30 = 900

Find the value of r in(4,r) (r,3) so that the slope of the line containing them is 0
Answer:
r = 3.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope.
Finding the slope of a line, given two points:
When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.
Points (4,r), (r,3)
Change in y: 3 - r
Change in x: r - 4
Slope is 0, so:
[tex]\frac{3 - r}{r - 4} = 0[/tex]
[tex]3 - r = 0[/tex]
[tex]r = 3[/tex]
The value is r = 3.
A square with sides x ft long has a perimeter of 34 1/2 ft. How long are the sides of the square
Answer:
8.625 ft for each side.
Step-by-step explanation:
This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th is 9 (although i doubt saying 1th is right, but just because).

A track coach is gathering data on the stride length of each of her 52 team members when running a distance of 500 meters. The population
mean is 62.95 inches with a standard deviation of 5.65 inches.
What is the standard error of the sample mean? Round your answer to the nearest hundredth.
The standard error of the sample mean is approximately
The standard error of the sample mean is 0.7835140.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given:
Population mean = 62.95
Population standard deviation = 5.65
Sample size = 52
The standard error of the sample mean :
= Standard deviation / √(sample size)
= 5.65 / √(52)
= 0.7835140
Hence, the standard error is 0.7835140.

Gabby picked out a handful of jellybeans. She chose 8 red, 3 yellow, 5 black, and 2 orange. What is the ratio of yellow jellybeans to total jellybeans?
Answer:
The ratio of yellow jellybeans to total jellybeans is 1:6.
Step-by-step explanation:
The ratio of yellow jellybeans to total jellybeans is given by the number of yellow jellybeans divided by the number of total jellybeans.
In this question, we have that:
There are 3 yellow jellybeans.
In total, there are 8 + 3 + 5 + 2 = 18 total jellybeans.
So the ratio is:
3/18 = 1/6 = 1:6
The ratio of yellow jellybeans to total jellybeans is 1:6.
