<span>Simplifying 9e + -7 = 7e + -11
Reorder the terms: -7 + 9e = 7e + -11
Reorder the terms: -7 + 9e = -11 + 7e
Solving -7 + 9e = -11 + 7e
Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right.
Add '-7e' to each side of the equation. -7 + 9e + -7e = -11 + 7e + -7e Combine like terms: 9e + -7e = 2e -7 + 2e = -11 + 7e + -7e
Combine like terms: 7e + -7e = 0 -7 + 2e = -11 + 0 -7 + 2e = -11
Add '7' to each side of the equation.
</span><span>Combine like terms: -7 + 7 = 0 0 + 2e = -11 + 7 2e = -11 + 7
</span><span>Combine like terms: -11 + 7 = -4 2e = -4
Divide each side by '2'. e = -2
Simplifying e = -2</span>

Solve the simultaneous equation

Mashutka [201]

First of all, we can simply the first and second equations by $2$ and $3$ , respectively, to get

$x+y+2z=12$

$2x+y=5$

$y+2z=11$

If we subtract the third equation from the first, we already figure out that $x=1$ . The system becomes

$y+2z=11$

$y=3$

$y+2z=11$

so we know $y=3$ as well. Let's plug the values for $x$ and $y$ in any of the three equations to get

$y+2z=11 \iff 3+2z=11 \iff 2z=8 \iff z=4$

So, the solution is $x=1$ , $y=3$ , $z=4$

If f(x)= -4x + 3 and g(x) = 3x² + 2x - 4 find (f+g)(x)

pychu [463]

Answer:

A

Step-by-step explanation:

We have the two functions:

$f(x)=-4x+3\text{ and } g(x)=3x^2+2x-4$

And we want to find (f+g)(x).

Note that this is the same thing to f(x)+g(x). Therefore:

$\begin{aligned} (f+g)(x)&=f(x)+g(x) \\ &=(-4x+3)+(3x^2+2x-4) \end{aligned}$

We simply substituted them for their equations.

Simplify. Combine like terms:

$=(3x^2)+(-4x+2x)+(3-4)$

Add:

$=3x^2-2x-1$

Hence, our answer is A.

Using the GCF you found in Part b re write 35 +63 factor one factor is the GCF and the other is the sum of the two numbers that

liraira [26]

Answer:

7(9 + 14)

Step-by-step explanation:

The Greatest Common Factor of 35 and 63 is 7; both 35 and 63 are evenly divided by 7. Thus, 35 + 63 can be rewritten as 7(5) + 7(9), or 7(14)

So 35 + 63 = 7(9 + 14)
