Answer:

-6.

Step-by-step explanation:

The equation is y = -7x - 6.

The initial value is found when x = 0.

y = -7(0) - 6

y = 0 - 6

y = -6

Hope this helps!

Rewriting the Equation:

Answer:

7x+y=-33

Step-by-step explanation:

1.) Combine Like Terms: y=-7x-33

2.) Move the variable to the left side and use the inverse operation:

y+7x=-33

3.) Reorder terms using commutative property since x comes before y:

7x+y=-33

If you want to find the function then tell me.

Consider the quadratic equation x squared = 4x - 5. how many solutions does the equation have?

snow_lady [41]

Answer:

The quadratic equation has two complex solutions

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}=4x-5$

Equate to cero

$x^{2}-4x+5=0$

$a=1\\b=-4\\c=5$

substitute in the formula

$x=\frac{4(+/-)\sqrt{-4^{2}-4(1)(5)}} {2(1)}$

$x=\frac{4(+/-)\sqrt{16-20}} {2}$

$x=\frac{4(+/-)\sqrt{-4}} {2}$

Remember that

$i^{2}=-1$

$x=\frac{4(+/-)2i} {2}$

$x=2(+/-)i$

therefore

The quadratic equation has two complex solutions

Write each as a fraction or mixed number in lowest terms 6.05 12.346 7.5

AVprozaik [17]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the decimal number

$6.05$

Rewrite as

$=6+0.05$

$=6+\frac{5}{100}$ ∵ 0.05 = 5/100

$=6+\frac{1}{20}$

$=\:\frac{121}{20}$

$=6\frac{1}{20}$

Given the decimal number

12.346

Rewrite as

$=12+0.346$

$=12+\frac{173}{500}$ ∵ 0.346 = 346/1000 = 173/500

$=12\frac{173}{500}$

Given the decimal number

7.5

Rewrite as

$=7+0.5$

$=7+\frac{1}{2}$ ∵ 0.5 = 1/2

$=7\frac{1}{2}$

Explain two methods for solving an equation. Give an example.

svlad2 [7]

For solving system of equations, we can use either substitution where we plug one equation into the other, or elimination where we combine the equations.

- Using elimination, you would to eliminate one variable from both equations, so you automatically would get one equation with one variable!

- Using substitution means you are going to solve one equation for one variable and substitute with its value in the other equation in order to get also an equation with one variable.

Let's take an example ...

y+x=2 and y-2x = 1

Using elimination, we need to subtract these two equation; one from the other...

y+x=2
-
y-2x=1
-----------
0+3x=1

then x=1/3

and then substitute into any equation to get y-value
y+x=2
y+1/3 = 2 >>>>> y=5/3

NOW...Using substitution
y+x=2 and y-2x = 1 >>(y=1+2x)

Plug (y=1+2x) into y+x=2 and solve for x
y+x=2
(1+2x) + x =2
1+3x = 2
3x=1

again (and for sure) x = 1/3

plug in x=1/3 into any of the equations above to get y:
y+x=2
y+1/3=2
y=5/3

I hope you got the idea

How do you solve 7n-2=6n-2n

pantera1 [17]

First combine like terms:
6n-2n = 4n
7n-2=4n
subtract 7n from both sides
7n-2=4n
-7n -7n
-2=-3n
divide -2 on both sides.
n=1.5
