Answer:
There are no values of a that make the equation true. No solution
Step-by-step explanation:
Step-by-step explanation:
In this problem, all we have to do is replace x and y with the values we've been given.
It can be helpful to think of 3x as 3 * x (which is the same exact thing), so I'll write it out that way.
3*x - 4*y
(replace)
3*4 - 4*3
(multiply (doing this step first because of PEMDAS))
12 - 12
(subtract)
0
Answer:
0
Answer:
x = 10.296
y = 5.831
Step-by-step explanation:
You can use the Pythagorean theorem to solve the triangles shown in various ways.
9²+5²=x²
x = 10.296
5²+3²=y²
y = 5.831
Since 36,189 falls between 36,150 and 36,200 use 4980. 4980-3825=1,155 The answer is b) $1,155
Answer:5 + /- sqrt35
Step-by-step explanation:
Rearranging, we get x^2 -10x -10=0
Applying the quadratic formula,
(10 +/- sqrt(10^2 -4*-10))/2
(10+/- 2sqrt35) /2 = 5 + /- sqrt35 as the two roots.
