Answer:
If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.

Answer:
3.0
Step-by-step explanation:
The angle, its opposite side, and the hypotenuse are given. Then the relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(21°) = x/8.3 . . . . . . . . . . . . . . . . . . use the given values
x = 8.3·sin(21°) ≈ 8.3×0.3584 . . . . . . multiply by 8.3
x ≈ 3.0
Answer:
7.5
Step-by-step explanation:
the slope m is a measure of the rate of change
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (6, 45 ) and (x₂, y₂ ) = (9, 67.5 )
m = 
= 
= 7.5 ← rate of change
Answer:
In slope-intercept form:
In standard form:
Step-by-step explanation:
When they graphically intersect, the two equations are equal and we can say that y=y so:
4x+2=x+5 subtract 2 from both sides
4x=x+3 subtract x from both sides
3x=3 divide both sides by 3
x=1, which makes y=x+5 become:
y=1+5=6, so the solution to the system of equations is the point:
(1,6)
The only graph containing this point is the top one on the first page...
