Answer:
Step-by-step explanation:
Yay graphs!!!!!!
Okay so as you should know, the structure of a linear equation is y = mx + b.
B is the y-intercept
so the first thing to do is mark the coordinates (0,1) as the y-intercept
Now the slope is 1/4 x
this is also known as rise/run
A simpler way to do that is from (0,1) move up 1 and over four and place a point there
The coordinate should be (4,1)
Then draw a line through the two points
Answer:
x = 1/2 y = -5/2
Step-by-step explanation:
Since we already know an equation for y, we just need to plug it into the other equation.
21x - 7(-5x) = 28
21x + 35x = 28
56x = 28
x = 1/2
Now that we know x, we substitute it into the other equation, to find y.
y = -5x
y = -5(1/2)
= -5/2
Answer:
x+1
Step-by-step explanation:
x * 2 -3 - x + 4 =
2x - 3 - x + 4
x - 3+4 = x+1
Answer: 4 people
Step-by-step explanation:
4 times 1/5= 4/5
The 4 goes on top ( numerator ) and the 5 would go on the bottom ( denominator )
Also another way to solve this is to use decimal form.
4 times 0.2 ( 0.2=1/5 )= 0.8
