x^2+6x+4= -2x+4
Answer:
0,-8
Answer explanation:
x^2+6x+4=-2x+4
or, x^2+6x+4+2x-4=0
or, x^2+8x=0
Therefore, x(x+8)=0
Either,
x=0
or,
x+8=0
x=-8
hence,x=0, -8

Answer:101
Step-by-step explanation:
The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the
yavariable, and what is the solution for this system?
x + 3y - 42
2x-y-14
OA. Multiply the second equation by-3. The solution is x = 12. y - 9.
ов.

Answer:
D. Multiply the second equation by 3. The solution is x = 12, y = 10
Step-by-step explanation:
Given:
x + 3y = 42 (first equation)
2x - y = 14 (second equation)
To solve by elimination, starting with elimination of the y-variable, multiply the second equation by 3 to get a third equation.
2x - y = 14 (2nd eqn.) × 3
6x - 3y = 42 (3rd equation)
Add the 3rd equation and the 1st equation together.
x + 3y = 42 (first equation)
6x - 3y = 42 (3rd equation)
7x = 84
7x/7 = 84/7
x = 12
To find y, substitute x = 12 in the first equation
x + 3y = 42 (first equation)
12 + 3y = 42
12 + 3y - 12 = 42 - 12
3y = 30
3y/3 = 30/3
y = 10
Solution is x = 12, y = 10

all real values of x where x < −2
all real values of x where −2 < x < 4
all real values of x where 1 < x < 4
all real values of x where x < 0
The values for which the graph is negative and increasing are all real values of x where 1 < x < 4.
Given
The graph of function;
A graph goes from being negative to positive (or the other way around) by passing through the x-axis. in other words when f(x) = 0.
Then,
For increasing and decreasing for anything other than a quadratic and linear function you need calculus.
The function is negative below the zeros which would be from -2 to 4.
It would be increasing from the vertex to zero,4.
Hence, the values for which the graph is negative and increasing are all real values of x where 1 < x < 4.
