Option A: 3 is the right answer
Step-by-step explanation:
Given
In an ordered pair, the x-coordinate is the input to the function and y-coordinate is the output of the function on specified input.
In the given ordered pair,
x-coordinate is -2 so we will put it into the function to get the y-coordinate
So,
3 will complete the ordered pair of the point on the graph
Hence,
Option A: 3 is the right answer

Answer:
(-5,-6)
Step-by-step explanation:
Let(-3,-9)=(x1,y1)
(-7,-3)=(x2,y2)
Using midpoint formula,
Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)
=((-3+(-7))/2,(-9+(-3))/2))
=((-3-7)/2),(-9-3)/2))
=((-10/2),(-12/2))
=(-5,-6)
Thus midpoint(x,y)=(-5,-6)
Product of 8 and the sum of 4 and a number:
sum of 4 and a number: (4 + n)
Product of 8
8 x (4 + n) is 112
8 x (4 + n) = 112
Distribute
32 + 8n = 112
Subtratc
8n = 80
Divide by 8
n = 10
The number is 10, and next time please put options because it says "Which equation could be used to solve for the number?" Thanks! :)
Answer:
x = - 3
Step-by-step explanation:
Given
5x - 4 = x - 16 ( subtract x from both sides )
4x - 4 = - 16 ( add 4 to both sides )
4x = - 12 ( divide both sides by 4 )
x = - 3
Answer:
-31/26
Step-by-step explanation:
To find the slope
m= ( y2-y1)/(x2-x1)
= ( 15 - -16)/(-7 - 19)
= ( 15+16)/(-7-19)
= 31/ -26
-31/26
