4x+ 3 = 3(2x-5) ;x=2; x^{2} = 4
Answer:
Options A, C and F are correct
Step-by-step explanation:
The expression in the question has a slight error in it
<em>"17.75x + 24 = 18.95x + 18"</em> is mearnt to be 17.95x + 24 = 18.95x + 18
Options A, C and F is correct
Given the expression for the situation
17.95x + 24 = 18.95x + 18
collect like terms
17.95x-18.95x=18-24
-x=-6
divide both sides by -1 and solve for x we have
x=6

Cramer's rule is an explicit formula for the solution of a system of linear equations. That has many equations as unknowns and valid whenever the system has a unique solution.

Answer:
y = x + 7
Step-by-step explanation:
The line has a "rise" of 1 grid square for each "run" of 1 grid square to the right. (It passes through successive grid intersections.) This means it has a slope of ...
m = slope = "rise"/"run" = 1/1
m = 1
The line crosses the y-axis at y = 7, so the y-intercept is ...
b = 7
Then the slope-intercept form equation is ...
y = mx + b
y = x + 7
Answer:
a. 14 is a coefficient, and b is a variable.
This can be expanded to 14*b
b. 30 is a coefficient, and j and k are variables.
This can be expanded to 30*j*k
