Answer:
y= 2,75
Step-by-step explanation:
6 = 3 + 5 (y-2)
6=8(y-2)
6/8=y-2
¾=y-2
0,75+2=y
y= 2,75
From lea st to greatest it would be 6.200, 6.4, 6.532, and 6.6
Answer:
The two numbers are <em>13</em> and <em>48</em>.
Step-by-step explanation:
We can create two simultaneous equations to solve this question using the information given.
Let number 1 = x
Let number 2 = y
x + y = 61 -> ( 1 )
x = y + 35 -> ( 2 )
We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier and shorter option.
Substitute ( 2 ) into ( 1 ):
x + y = 61 -> ( 1 )
( y + 35 ) + y = 61
2y + 35 = 61
2y = 26
y = 26 / 2
y = 13 -> ( 3 )
Substitute ( 3 ) into ( 2 ):
x = y + 35 -> ( 2 )
x = ( 13 ) + 35
x = 48
Therefore:
x = 48 , y = 13
Find 2 points on the line:
We will use (2,2) and (0,-6)
Find the slope of the line which is the change in Y over the change in X:
(-6-2) / (0-2) = -8/-2 = 4
The slope = 4
Find the Y intercept:
y = 4x+b
use y1 for y and x1 for x
2 = 4(2) +b
2 = 8 +b
Subtract 8 from both side:
b = -6
Now you have the slope (4) and Y intercept (-6)
The equation of the line becomes y = 4X-6
The line is solid and the shaded portion of the graph is to the left of the line and it is a positive slope so the inequality would become
y ≥ 4x -6
Answer:
18
