Answer:
-40
Step-by-step explanation:
Let's input x into all of the slots.
Now, let's solve!
So, the answer is -40!
Answer:
x=1
y=2
Explanation:
first start with assigning a random value to a variable
lets say x=1
from there the equation becomes solveable
-6x1+7y=8
simplify
-6+7y=8
+6 to both sides
7y=14
divide both sides by 7
y=2
from here we can say that x=1, y=2, can satisfy the equation-6x+7y=8
hope this helps :)
Answer: B. 2=3x+10x^2
Step-by-step explanation:
The expression means the quadratic function equation.
B = 10x^2 + 3x -2 = 0
the equation is [-b ±√(b^2 -4ac)]/2a
b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
I’m assuming you just substitute 2 in the equation for x:
4 + x = 4 + 2 = 6
Answer = 6
