Which statements are true about the ordered pair (7, 19) and the system of equations?
{2x−y=−5x+3y=22
Select each correct answer.
The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (7, 19) is a solution to the system because it makes both equations true.

To make a friendship bracelet, some long strings are lined up then taking one string and tying it in a knot with each of the other strings to creat a row of knots. A new string is chosen and knotted with the all the other strings to create a second row. this process is repeated until there are enough rolls to make a bracelet to fit around your friends wrist. Are the number of knots proportional to the number of rows?

Carla passes fertilizer on Amistad's yard. She covers 150 square feet every 3 hours. How many square feet per hour does Carla cover? Explain your reasoning.
Answer:
50 square feet
Step-by-step explanation:
150/3= 50
Answer:
the answer is 50
Step-by-step explanation:
if she does 150 square feet every 3 hour
you need the 3 hours down to 1 so in order to do that
you need to divide 3 by 3
what you do to one side must be done to the other
150 by 3
so it will look like
3/3 = 150/3
1 = 50

The cost of 4 bananas is $2.36. What is the cost of each banana?
Mario's Work. StartFraction b Over 4 EndFraction = 2.36. A number line going from 9.41 to 9.49. A point is at 9.44.
Juan's Work. 4 b = 2.36. A number line going from 0.51 to 0.59. A point is at 0.59.
Daviana's Work. B minus 4 = 2.36. A number line going from 6.31 to 6.39. A point is at 6.36.
Answer:
B i think
Step-by-step explanation:
Juans work is correct because the equation to find cost of each banana is 4b=$2.36
What is Number system?A number system is defined as a system of writing to express numbers.
Given that the cost of 4 bananas is $2.36
We have to find the cost of each banana.
To find this we have to divide the cost by number of bananas
Divide two point three six by four
Banana is denoted by b
4b=$2.36 is the required equation
Cost of each banana =$2.36/4
=$0.59
Hence, Juans work is correct because the equation to find cost of each banana is 4b=$2.36

Answer: output = -1n + 7 or -n + 7
n can represent any number.
Step-by-step explanation: using the slope-intercept form y = mx + b
y is the output. x is any input. m is the slope. b is the constant.
Calculate the slope: rise ÷ run
You see all the inputs in the chart are going up by 1. This is the run +1
You see all the outputs going down by 1. This is the rise: -1
So the slope, m, is rise / run . -1/1 = -1
To find the constant, use the slope with any pair of inputs and outputs from the chart in place of y and x in the slope-intercept equation.
y = mx + b becomes 6 = -1(1) + b . Solve for b
6 = -1 + b
6 +1 = -1 +1 + b
7 = b
Now set up the equation that answers the question using the calculated values of m and b.
y = -1(x) + 7 . We can answer the question with this equation rewritten a bit:
Output = -1n + 7
or -n + 7 as 1 is usually implied.

Find the x−and y−intercepts of −2x − 12y = 24.
Will give Brainliest!
Answer:
X= -12 -6y, Y= -2- x/6
Step-by-step explanation:
For x
-2x-12y=24
-2x/-2 -12y/-2. 24/-2. Divide all by -2
X+6y=-12 this is what you get after
-6y. -6y. Subtract from both sides
X=-12-6y this is what you get
Find y
-2x-12y=24
-2/-2. -12/-2. 24/-2
X -6y=-12
-x. -x
-6y=-12-x
-6y/-6. -12/-6. -x/-6
Y = -2 - x/6

Answer:
x =∅ (No solution)
Step-by-step explanation:
First, simplify each side by combining like terms:
3x + 5 = 14 + 3x
So you want to get x to one side and everything else to the other. Subtract (3x) and (5) from each side.
0 = 9
Because 0 does not equal 9, there are no solutions.
Find the angle measures. Justify your responses. Given: a||b, m1=71º Find m5, m8
I NEED THIS ANSWER BY TUESDAY THE 1ST!!! PLEASE ANSWER!!!
Answer:
The measure of angle MNP is
m ∠ MNP = (x - y)/2
Explanation:
The image attached shows the figure corresponding to this question.
The angle MNP, which is also the angle LNP, is formed by the intersection of a secant and a tangent to a circle.
Then, you can use the theorem:
the angle formed by a secant and a tangent to a circle that intersect outside the circle is half the difference of the major arc minus the minor arc.
The major arc formed is identified with the letter x and the minor arc is identified with the letter y. Thus, the measure of the angle MNP is half the difference x - y:
m ∠ MNP = (x - y)/2
