Answer:
Equation 3: y = 12x + 17
Step-by-step explanation:
Only a linear equation (degree 1) will have a graph that is a straight line.
- Equation 1: degree 2
- Equation 2: degree 5
- Equation 3: degree 1
- Equation 4: degree 4
The degree of the equation is the highest power of any of the variables. If different variables are in the same term, it is the sum of the powers of those variables.
3(x+4)=9
3x+12=9
3x=-3
x=-1
Hope this helps :D
Answer:
y=-5x+2
Step-by-step explanation:
rise/run
or
y2-y1/x2-x1
-8-(-3)/2-1
-8+3/2-1
-5/1=m=slope
Slope intercept formula:y=mx+b
use point (1,-3)
-3=-5(1)+b
-3=-5+b
+5 +5
2=b
Final Answer: y=-5x+2
Answer:
<em>Alex sold 330 white chocolate bars</em>
Step-by-step explanation:
let the milk chocolate candy be x and the white chocolate candy be y. then
then 2x+3y=990----1)
x+y=330-----2)
from eq 2) ⇒ x=330-y---------3)
Putting eq 3 in eq 1
2(330-y) +3y=990
660-2y+3y=990
y=990-660=330-----------4)
Putting eq4 in eq1
2x+3(330)=990
2x+990=990
2x=990-990
2x=0
x=0---------------------------5)
