First, we would set the number to x.
Then, we turn the words into an equation.
x+75 = 3x-39
Isolate the x.
-2x = -114
So...
x = 57
Answer: Write a quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10). (what does F(x)=?) Algebra -> Quadratic Equations and Parabolas -> SOLUTION: Write a quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10).
Step-by-step explanation:
The answer is 15.92
This comes from the use of any of the trig functions, but you want to pick whichever one fits best. Since we are given the angle 53 degrees and the adjacent side that measures 12, and we want to find the opposite side, we can simply enter these values into our trig function.
Tan(53deg) = x / 12
Tan(53deg) * 12 = x
1.32704482 * 12 = x
x = 15.92454
Y=2x+5
sub 2x+5 for y in other equaiton
10x+3(2x+5)=19
distribute
10x+6x+15=19
minus 15 from both sides
16x=4
divide both sides by 16
x=1/4
sub back
y=2x+5
y=2(1/4)+5
y=1/2+5
y=5.5=11/2
solution is (1/4,11/2) or in decimal, (0.25,5.5)
