Answer:
16
Step-by-step explanation:
This question can be modeled using the equation 3x+4=52 (x is the purple marbles). To solve this equation subtract 4 from both sides, making it 3x=48. divide both by three showing x=16. This shows that 16 is the answer.
Answer:
6x + 2(−2x + 1) = 22
Step-by-step explanation:
6x + 2(−2x + 1) = 22
This step can be used to solve by substitution method.
Answer:
x = 5/2 & x = 1/3
Step-by-step explanation:
Create two equations and solve
1) 2x-5 = 0 & 2) 3x-1 = 0
1) 2x = 5
x = 5/2
2) 3x = 1
x = 1/3
You create two equations as you want the left hand side (LHS) to equal 0 (RHS), thus if one of the brackets becomes 0 it will result in the whole LHS beocming 0 as the brackets are being multiplied (anything multiplied by 0 = 0)
Try to be more clear with this question. but, if I understood it correctly, g(x) would be the '' equation'' for a FUNCTION.
Hope it helps!!
Answer:
y=−2x+5
Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is
y=mx+b , where m is the slope and b is the y-intercept.
y=mx+b
Find the values of
m and b
using the form
y=mx+b.
m=−2b=5
The slope of the line is the value of m , and the y-intercept is the value of
b.
Slope: −2
y-intercept:
(0,5)
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Graph the line using the slope and the y-intercept, or the points.
Slope: −2
y-intercept: (0,5)
