Answer:
y = -4
Step-by-step explanation:
We can find the equation of a line that goes through two given points on the plane by finding 1) the slope of the segment that joints the two points, and using the coordinates of one of the given points, and use this information in the "point-slope" form of the line.
To find the slope of the segment that joins the two points, we use the general equation for the slope given two coordinate pair points as:
In our case, using the given (-3,-4) as , and (1,-4) as , we get the following slope:
Therefore, the slope is zero (this means we are dealing with a horizontal line.
Now we complete the work by using the point-slope form of a line which is:
Using one of the given points (let's say (1,-4) as , and the slope (0) that we just obtained, we get the following equation for the line in question:
So y = -4 is the expression for the line
Answer:
It is 23
Step-by-step explanation:
BC= FE
(x-4)=19
Therefore x= 23
The answer is C because when you use the vertical test it only passes through one line
Answer:
Activity 1 of 2 : 25 adult servings.
Activity 2 of 2 : $13.6
Step-by-step explanation:
Activity 1 of 2 :
2/5 of a pound per adult serving.
10 pounds of turkey.
0.4 ÷ 10 = 25
2/5 ÷ 10 = 25
25 adult servings.
^ same equation
Activity 2 of 2 :
$1.36 per pound.
10 pounds.
1.36 * 10 = 13.6
$13.6
Hey there! :)
Equation 1) -2x + y = 14
Equation 2) 4x - 6y = 4
Add 2x to both sides of equation 1 so that we can get the value of y.
y = 2x + 14
Now, plug the value of y into our second equation.
4x - 6(2x + 14) = 4
Simplify.
4x - 12x - 84 = 4
Add 84 to both sides.
4x - 12x = 4 + 84
Simplify.
-8x = 88
Divide both sides by -8.
x = -11
Now, plug our value of x into our first equation in order to find y.
-2x + y = 14
-2(-11) + y = 14
22 + y = 14
y = -8
Therefore, the systems of equation variables are : (-11, -8)
~Hope this helped! :)
