=Y2-10Y

We move all terms to the left:

-(Y2-10Y)=0

We add all the numbers together, and all the variables

-(+Y^2-10Y)=0

We get rid of parentheses

-Y^2+10Y=0

We add all the numbers together, and all the variables

-1Y^2+10Y=0

a = -1; b = 10; c = 0;

Δ = b2-4ac

Δ = 102-4·(-1)·0

Δ = 100

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

Y1=−b−Δ√2aY2=−b+Δ√2a

Δ‾‾√=100‾‾‾‾√=10

Y1=−b−Δ√2a=−(10)−102∗−1=−20−2=+10

Y2=−b+Δ√2a=−(10)+102∗−1=0−2=0

The inverse of the given function is y=±√(x+25)+5. Therefore, the option D is the correct answer.

Inverse function is represented by f⁻¹ with regards to the original function  and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.

The given function is y=x²-10x

Replace x with y and y with x.

x=y²-10y

x=y(y-10)

y=x/(y-10)

So, the equation is non-invertible, the equations of the graph gained by reflecting over y = x

y=±√(x+25)+5

Therefore, the option D is the correct answer.

Answer:

The interest rate is 2%

Step-by-step explanation:

Simple Interest

Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=P.r.t

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

The principal is P=$3,000 and it earned I=$300 in t=5 years. Thus the interest rate can be calculated by solving for r:

[tex]\displaystyle r=\frac{I}{P.t}[/tex]

[tex]\displaystyle r=\frac{300}{3,000*5}[/tex]

[tex]\displaystyle r=\frac{300}{15,000}[/tex]

r = 0.02

The interest rate is 2%

Answer:

The exponential equation is y = -2×(1/2)^x

Step-by-step explanation:

Ok we have a couple things to note here:

1) The horizontal asymptote of the function is the x axis (always nice)

2) At x=0, y=-2 (i.e, this function will be multiplied by -2 bc the exponent part will transform into one at x=0)

3) Then we need to ascertain the base of the exponential. Based on the facts that at x=1, y=-1 and the "a-value" is -2, we can set up an equation to find b:

y=a×b^x----> -1 = (-2)(b) ------> b=1/2

Therefore, the exponential equation is y = -2×(1/2)^x

Test:

At x = 0, y= -2

At x = -1, y = (-2)*(1/2)^-1 = (-2)*2 = -4

At x=2, y = (-2)*(1/2)^2= (-2)*(1/4) = -1/2

Thus we can be quite certain that this is correct

The angles that are equal are called congruent angles.

The angles that appear to be congruent are

Angle 1 and Angle 5.

Option B is the correct answer.

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

The figure of different angles.

We can assume the angles as:

Angle 1 = 45°

Angle 2 = 135°

Angle 3 = 90°

Angle 4 = 20°

Angle 5 = 45°

We see that,

Angle 1 and Angle 5 are congruent.

Congruent angles mean the angles are equal.

Thus,

The angles that appear to be congruent are

Angle 1 and Angle 5.

Option B is the correct answer.

Step-by-step explanation:

Divide both numbers together.

-0.5g-1.5=-6.5

We move all terms to the left:

-0.5g-1.5-(-6.5)=0

We add all the numbers together, and all the variables

-0.5g+5=0

We move all terms containing g to the left, all other terms to the right

-0.5g=-5

g=-5/-0.5

g=+10

Answer:

g=10

Step-by-step explanation:

Add 1.5 to both sides and cancel out the -1.5 on the left side. Then you'll have -0.5g=-5

Then you divide by -0.5 and isolate the variable, which means that the g will be by itself, and -5 divided by -0.5 is equal to 10.

So g=10

Step-by-step explanation:

happy valentines!

Answer:

No, It does not.

Step-by-step explanation:

(3,4) means (x,y). When you insert 3 to x and 4 to y, You get this:

5(3)-9(4)=32

If you multiply 5 and 3, You get 15.

15-9(4)=32

If you multiply 9 and 4, you get 36.

15-36=32

If you subtract 15-36, you get -21.

This is why the answer is no because -21 does not equal 32

-21 ≠ 32
