X^2 + y^2 = 5
y = 2x

The second equation is solved for y, so substitute it in the first equation.

x^2 + (2x)^2 = 5

x^2 + 4x^2 = 5

5x^2 = 5

x^2 = 1

x^2 - 1 = 0

(x + 1)(x - 1) = 0

x = -1 or x = 1

Now substitute both values of x in the second equation and solve for y.

y = 2x

For x = -1

y = 2(-1)

y = -2

For x = 1

y = 2(1)

y = 2

Solution: (-1, -2), (1, 2)

Select the correct answer. Shape 1 and shape 2 are plotted on a coordinate plane. Which statement about the shapes is true? A. S
IceJOKER [234]

Answer:

Since I cant say which answer due to no graph, I'll tell you How to do so.

Step-by-step explanation:

if it is A, then the there is at least one angle or line length that is not the same. To find the area of a grided shape, use the traingle theorm of a^2+b^2=c^2.

if it is B, that meants moving the shape to the other will result in a perfect fit. Be sure to find if all side lengths are the same as that means that the shape IS congrouent, as equal side length means equal angles. However, it will not be this choice if the shape is mirrored to the other

A rotation and tranlastion means it is flipped either upside down or up and moved to the shape.

D, a reflection, which means its the opposite. Like a mirrored shape. Then you move it.

Evaluate f (x) = 3 (2)x for x=-1
kap26 [50]

The value of the function at x = -1 is 5

<h3>What is  function?</h3>

Function can be defined as an expression, rule, or law that defines a relationship between one variable known as the independent variable and another called the dependent variable.

From the information given, we have that;

f (x) = 3 (2)x  with  x=-1

Now, let's substitute the value of x as - 1 in the function given;

f (x) = 3 (2)x

f (x) = 3 (2) -1

Expand the bracket;

f (x) = 6 - 1

f(x) = 5

Thus, the value of the function at x = -1 is 5

John paid $80 for 5 tickets at an amusement park. Each of the tickets cost the same price. Which equation represent the cost, C,
cupoosta [38]
Since it’s $80 for 5 tickets, we divide 80/5 to get the price of one ticket, giving us

C = 16*n.

Plug in 5 for n and you’ll get 80
