Y=mx+b
m=slope
b=yintercept
input points
when x=1
y=1
1=1m+b
and
x=2
y=-2
-2=2m+b
multilpy first equaiton by -1 and add to othe requation
-1=-m-b
<u>-2=2m+b +</u>
-3=m+0b
-3=m
y=-3x+b
1=-3(1)+b
1=-3+b
add 3
4=b
y=-3x+4
first blank is -3
second is 4
Answer:
5.25x + 55 is greater than or equal to 399
Step-by-step explanation:
55 is a fixed amount of money that Amelia already has so that will be added to the part of the eqaution: 5.25x.
Her total should be greater than or equal to $399
<h3>
Taking into account that their ages are:</h3>
- Alvin=.....................x+11
- Elga=.......................x
<h3>x + 11 + x = 107</h3>
Step 1: Simplify both sides of the equation.
<h3>x + 11 + x = 107</h3>
(x + x) + (11) = 107 (Combine Like Terms)
<h3>2x + 11 = 107</h3>
Subtract 11 from both sides.
<h3>2x + 11 − 11 = 107 − 11</h3><h3>2x = 96</h3>
Divide both sides by 2.
<h3>2x/2 = 96/2</h3><h3>x = 48</h3>
