What is the solution to the system of equations? y=2/3x+3 x=-2

Answers

Answer 1

Answer:

Answer:

$x=-2,y=(5)/(3)$

Step-by-step explanation:

The given system of equations is

$y=(2)/(3)x+3...(i)\n\nx=-2...(ii)$

Plugging the value of x from (ii) in equation (i) and find the value of y

$y=(2)/(3)*(-2)+3\n\ny=(-4)/(3)+3\n\ny=(5)/(3)$

Therefore, the solution of the system of equations is

$x=-2,y=(5)/(3)$

Answer 2

Answer: We are going to solve for x=-2, y=2/3x+3, y=2/3(-2)+3, y=5/3. Therefore, x=-2 and y=5/3

Which statement is true about the solution to the set of equations?

It is (1, 2).
There are infinitely many solutions.
It is (2, 2).
There is no solution.

Answers

Line A: 2x+2y=8 ⇒2y=-2x+8 ⇒ y=-x+4
Line B: x+y=3 ⇒y=-x+3

Therefore: y=y then:

What is 7/8 x c for c=8

Answers

Answer:
7

Explanation:
We are given the equation:
$(7)/(8)$ * c

We want to get the value of the equation at c = 8.
Therefore, all we have to do is substitute c in the equation with 8 and solve as follows:
$(7)/(8)$ * 8

= $(7*8)/(8)$

The 8 in the numerator will be cancelled out with the 8 in the denominator leaving us with only the 7 as a solution

Hope this helps :)

Answer:

Value is 7

Step-by-step explanation:

We are given the expression, $(7)/(8)* c$ .

It is required to evaluate the expression for c= 8.

So, after substituting the value of c= 8 in the given expression, we get,

$(7)/(8)* c$ = $(7)/(8)* 8$ = 7

Hence, the value of the expression at c= 8 is 7.

Using the completing-the-square method, rewrite f(x) = x2 − 8x + 3 in vertex form.

Answers

f(x) = x² - 8x + 3
y = x² - 8x + 3
- 3 - 3
y - 3 = x² - 8x + 16
y - 3 + 16 = x² - 8x + 16
y + 13 = x² - 8x + 16
y + 13 = (x - 4)²
- 13 - 13
y = (x - 4)² - 13
f(x) = (x - 4)² - 13

Max or min value y=3x^2+6x-5

Answers

$y = 3x^2+6x-5$

For a parabola $ax^2+bx+c$ the vertex's x equals:

$(-b)/(a)$

$a = 3, b =6$

$x = (-6)/(2*3)$

refine:

$x = -1$

Plug in x = -1 to find the y value :

$y=3(-1)^2+6(-1)-5$

refine :

$y = -8$

Therefore the parabola vertex is :

$(-1,-8)$

if a < 0 , then the vertex is a maximum value

if a > 0, then then vertex is a minimum value

a=3

Therefore $(-1,-8)$ minimum

hope this helps!
