A + 4 = 8
a = 4
Can you add anything else to 4 to get 8? No.
4 - m = 2
-m = -2
m = 2
Can you subtract anything besides 2 from 4 to get 2? No.
So the statements are always true.
Answer:
X = 48.014%
Y = 51.986%
Step-by-step explanation:
Given
151 EU has a mass of 150.9196 amu
153 EU has a mass of 152.9209 amu
Calculating the relative abundance of the two EU isotopes.
First condition that must be satisfied is
X + Y = 100%;
X + Y = 1. ----- Equation 1
Second Condition is;
150.9196X + 152.9209Y = 151.96 ------ Equation 2
In Equation 1; make Y the subject of formula.
So, Y = 1 - X.
Substitute (1 - X) for Y in Equation 2
150.9196X + 152.9209(1 - X) = 151.96 ----Open bracket
150.9196X + 152.9209 - 152.9209X = 151.96 ---- Collect Like Terms
150.9196X - 152.9209X = 151.96 - 152.9209
−2.0013X = -0.9609
X = -0.9609/-2.0013
X = 0.480137910358267
X = 48.014% ----- Approximated
Y = 1 - X
Y = 1 - 48.014%
Y = 0.51986
Y = 51.986% ---- Approximated

Answer:
Slope-intercept: y=3/4x+1
Sorry idk how to do general form
Step-by-step explanation:
Slope-intercept form is y=mx+b, m being the slope, b being the y-intercept.
The slope of this graph is 3/4, and the y-intercept is 1.
