Answer:

Step-by-step explanation:

From the diagram:

P(-4,6)→P'(4,6);
Q(-7,4)→Q'(7,4);
R(-6,1)→R'(6,1);
S(-2,1)→S'(2,1);
T(-1,4)→T'(1,4).

The general rule of this reflection is

(x,y)→(-x,y)

and this is reflection across the y-axis. The y-axis has the equation x=0.

Answer:

x=6

Step-by-step explanation:

Hypotenuse is 10 because it is the opposite of the right angle

8^2+x^2=10^2

64+x^2=100

x^2=36

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at

stealth61 [152]

Using the formula for simple interest, it is found that he paid $119.87 in interest.

The simple interest formula is given by:

$E = PIt$

E is the amount of interest earned.
P is the principal(the amount of money invested).
I is the interest rate(yearly, as a decimal).
t is the time, in years.

In this problem:

Borrowed $2,700, thus $P = 2700$
Interest rate of 3.5%, thus $I = 0.035$
From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is $t = \frac{423}{365} = 1.2685$

Thus, the interest paid was of:

$E = PIt = 2700(0.035)(1.2685) = 119.87$

$119.87.

How do u know if an equation is linear?

krek1111 [17]

Answer:

An equation is linear if its graph forms a straight line. This will happen when the highest power of x is "1". Graphically, if the equation gives you a straight line then it is a linear equation. Else if it gives you a circle, or parabola or any other conic for that matter it is a quadratic or nonlinear equation.
