Answer:
13 , 35
Step-by-step explanation:
Let's call one of the number x and the other y
x + y = 47
x - y = 21 and x = 21 + y if we use this expression in the first equation instead of x we can find the value of y
x + y = 47 ➡ y + y + 21 = 47 add like terms
2y +21 = 47
2y = 47 - 21
2y = 26
y = 13 the value of first number is 13
x + y = 47 we know y is 13 so we can replace it
x + 13 = 47
x = 35
2x-9<7
2x<16
x<8
hope it helps
Answer:
C y= 2x +2
Step-by-step explanation:
Look at the graph and look at the dots. For example if you look at negative 1 on the x-axis there is a dot there. so it now you count up to where you see the next dot on the y-axis. Which it goes up 2, then count to the right towards the Y-Axis which is one. now you left with 2/1. since it is going up 2 it will be positive and 2 over 1 is simplified so you are left with 2x and the B will be 2 because the line goes through 2 on the y-axis. This equation should help you y=mx+b m is the slope and B is the y axis
