remember, you can do anything to an equation as long as you do it to both sides

we can do a subsitution

y=x+6

y=-7x-10

since y=x+6, we can subsitute x+6 for y in the other equation

y=-7x-10

x+6=-7x-10

add 7x to both sides

8x+6=-10

minus 6 from both sides

8x=-16

divide both sides by 8

x=-16/8=-2

the valu eof x that satisfies both equations is x=-2

y = x + 6

y = -7x - 10

---

Solve for x in the first equation. Subtract y and x from both sides.

-x = 6 - y

Divide both sides by -1.

x = -6 + y

---

Plug x into the second equation.

y = -7(-6 + y) - 10

Distribute -7 inside the parentheses.

y = 42 - 7y - 10

Combine like terms.

y = 32 - 7y

Add 7y to both sides.

8y = 32

Divide both sides by 8.

y = 4

---

Plug 4 for y into the first equation.

4 = x + 6

Subtract 6 from both sides.

x = -2

---

Your answer is -2; x = -2 satisfies both equations.

Which of the following is a trinomial?

Sedaia [141]

Answer:

$A) c^2 + c + 6$

Step-by-step explanation:

We have been given four choices out of which we need to select the choice which is trinomial.

Trinomial means polynomial having three terms.

A) c2 + c + 6

It has 3 terms.

B) c2 − 16

It has 2 terms.

C) −8c

It has 1 term.

D) c3 + 4c2 − 12c + 7

It has 4 terms.

We see that only choice A) has three terms.

Hence correct choice is $A) c^2 + c + 6$

The graph shows f(x)=(1/2)and its translation, g(x).

san4es73 [151]

The translation of four units up describes the transform function g(x) option first is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The question is:

The graph shows f(x)=(1/2)ˣ and its translation, g(x).

Which describes the translation of f(x) to g(x)?

Translation of four units up
Translation of five units up
Translation of four units to the right
Translation of five units to the right

The graph is attached please refer to the picture.

We have the equation of the function f(x):

$\rm f(x) = (\dfrac{1}{2})^x$

From the graph, we can see the graph of the function f(x) is shifted up 4 units because the y-intercept of the graph g(x) is (0, 5)

g(x) = f(x) + 4

$\rm g(x) = (\dfrac{1}{2})^x + 4$

Thus, the translation of four units up describes the transform function g(x) option first is correct.
