if a+3b=10, what is the value of 2a+6b=?
Answer:
20
Step-by-step explanation:
2(a+3b)=2(10)
The value of 2a + 6b is 20.
To find the value of 2a + 6b, we can use the given equation:
a + 3b = 10
Now, we want to find 2a + 6b, which is simply twice the value of "a + 3b."
2a + 6b = 2(a + 3b)
Now, substitute the value of "a + 3b" from the given equation:
2(a + 3b) = 2(10)
2a + 6b = 20
So, the value of 2a + 6b is 20.

Step-by-step explanation:
100 % edmentum
The solutions of the equation are x=-3+√42 and x=-3-√42.
The given quadratic equation is 2x²+12x=66.
What is completing square method?Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial.
Now, 2x²+12x=66 can be written as x²+6x-33=0
Add and subtract (b/2)² to the equation.
That is x²+6x-33+9-9=0
⇒x²+6x+9=42
⇒(x+3)²=42
⇒(x+3)=±√42⇒x=±√42-3
Therefore, x=-3+√42 and x=-3-√42.

Solve the system of equations x+y=-1 and 5x-7y=79 by combining the equations.
9514 1404 393
Answer:
(x, y) = (-6, -7)
Step-by-step explanation:
Multiply the first equation by 7 and add that to the second.
7(x +y) +(5x -7y) = 7(-1) +(79)
12x = 72
x = 6
y = -1 -x = -1 -6 = -7
The solution is (x, y) = (6, -7).

if you are writing equivalent expression for 2^3 · 2^4, how many times would you write 2 as a factor?
Answer:
7 times
Step-by-step explanation:
In order to find the answer to this question you have to remember that when dealing with exponents you need to multiply the number to itself as many times as the exponent. In this case we have 2^3 we then need to multiply two by itself three times because three is it's exponent.

Suppose that f(x) varies directly with x and f(x)=160 when x = 5.
What is f(x) when x = 0.5?
A: 16
B: 160
C: 32
D: 180
The required value of f(x) when x = 0.5 is 16.
Given,
f(x) varies directly with x .
f(x)=160 when x = 5.
We have to find f(x) when x = 0.5
According to the question ;
A function f(x) that varies directly with x. Direct variation is a case of variation expresses as the following form:
f(x) = kx
The value k is a nonzero constant greater than zero and is called the constant of variation.
This indicates that f(x) increases as x increases.
So,
f( x ) = kx
[tex]k = \frac{f (x) }{x}\\\\ k = \frac{f(5)}{5}[/tex]
[tex]k = \frac{160}{5}[/tex]
k = 32
When x = 0.5,
Then , f(x) = 32x
f(x) = 32(0.5)
f(x) = 16
The required value of f(x) when x = 0.5 is 16.
