Y=-2x+4 y=6x+12 substitution method

Mathematics
1 answer:
sergey [27]3 years ago
6 0

Answer:

x = - 1, y = 6

Step-by-step explanation:

Given the 2 equations

y = - 2x + 4 → (1)

y = 6x + 12 → (2)

Substitute y = 6x + 12 into (1)

6x + 12 = - 2x + 4 ( add 2x to both sides )

8x + 12 = 4 ( subtract 12 from both sides )

8x = - 8 ( divide both sides by 8 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

y = 6(- 1) + 12 = - 6 + 12 = 6

Solution is (- 1, 6 )

Answer:

a = 6.92820323 units

c = 2.828427125 units

Step-by-step explanation:

<u>Triangle one solution:</u>

<u />

\frac{a}{8} = sin 60

a = 8 × sin 60 = 6.92820323 units

<u>Triangle two solution:</u>

<u />

\frac{c}{4} = cos 45

c = 4 × cos 45 = 2.828427125 units

Question 1 of 10<br> (x)=x2. What is g(x)?<br> y<br> f(x)<br> g(x)<br> -5<br> 6<br> (3, 3)<br> 5
never [62]

The graph is attached and the answer to the function g(x) = (1/3)x²

Option A is the right answer.

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

A function is a mathematical statement that relates a dependent variable and an independent variable.

It is given that

f(x) = x²

It has been asked to determine the equation of g(x)

It can be seen from the graph the the vertex is same just the graph is scaled.

The point (3,3) is of g(x) , when the value of y at at x =3 is 9

Therefore the scale factor is 1/3

And we can do trial and error on the basis of the options given ,

The graph is attached and the answer to the function g(x) = (1/3)x²

Option A is the right answer.

Otero translated the phrase “three less than a number” into the expression 3-x. Which best describes the accuracy of Otero’s exp
xz_007 [3.2K]

Answer:

Option B is correct.

Step-by-step explanation:

Otero translated the phrase "three less than a number" into the expression 3 - x.

I think Otero gave a wrong expression for the phrase.

The true interpretation of the phrase is that if we assume the number as x then three less than a number means x - 3.

Therefore, Otero's expression is inaccurate. Three is being subtracted from a number, so x-3 is what he should have written. (Answer)
