Answer: c) y = x-1

Step-by-step explanation: took test on edge

Answer:

Given that BA = BC which shows that ΔABC is isosceles

And, ∠1 Represents BC

and, ∠2 Represents BA

And as BC and BA are equal, we come to know that ∠1 and ∠2 are equal

∠2 = ∠3 because they are opposite angles.

Therefore we can conclude that ∠1 and ∠3 are congruent because ∠1 =∠2 which ∠2 = ∠3 So, ∠1 = ∠3

If my answer helped, please mark me as the brainliest!!

Thank You!

Answer:

see below

Step-by-step explanation:

since ∠1 ≅ ∠2

opposite angles are equal

therefore, ∠2 ≅ ∠3

Answer:

[tex]-\frac{21}{2} x+5[/tex]

Step-by-step explanation:

To find the slope of the equation, you use [tex]\frac{rise}{run}[/tex] , or [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] :

[tex]\frac{-16-47}{2+4}[/tex]=[tex]\frac{-63}{6}[/tex]=[tex]\frac{-21}{2}[/tex]

Then you have to find the y intercept. First, plug in the x of a point and solve:

[tex]\frac{-21}{2}[/tex] * 2= -21

Then, find the distance between the answer and the y of the given point. Since our answer is smaller than the y of the point, we'll get a positive y- intercept.

21-16=5

This will give us the equation:

[tex]-\frac{21}{2} x+5[/tex]

20% = 0.20

95 x 0.20 = 19

95 - 19 = 76

Answer:

300 pennies. 12 quarters. 6 half dollars. 3 silver dollars. 60 nickles. 30 dimes.

Step-by-step explanation:

Pennies have a value of .01 so we add that to equal 300. For three dollars we need 12 quarters. 300 divided by the value of the quarter which is .25 cents. We have six half dollars (we divide 300 by the value of the half dollar). We would need 3 silver dollars since each is worth a dollar each. We would need 30 dimes (300 divided by 10).  Finally, we would need 60 nickels (300/5 = 60).

I hope this helps. Feel free to ask any questions.

Answer:

Andy is incorrect

Step-by-step explanation:

[See attachment for complete question]

Andy is incorrect because of the following.

Filling the empty boxes with any real numbers does not guarantee that the expression will be a polynomial.

For instance, if the expression is completed as thus:

(5x⁴ + 4x³)(4x^(2.7981) - 6) = A

This expression is not a polynomial because all powers of x must be non negative and it must be an integer.

So, Andy's statement is incorrect

Answer:

A burger cost five times as much as a fries.

Step-by-step explanation:

Let F represent fries

Let b represent burgers

From the question:

An order of fries and five burger can be written as:

f + 5b

Three orders of fries and two burgers can be written as:

3f + 2b

But an order of fries and five burgers cost twice as much as three orders of fries and two burgers. This can be written as:

f + 5b = 2(3f + 2b)

Now, we shall make b the subject of the above equation. This is illustrated below:

f + 5b = 2(3f + 2b)

Clear bracket

f + 5b = 6f + 4b

Collect like terms

5b – 4b = 6f – f

b = 5f

Thus, a burger cost five times as much as a fries.

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

Step 1: translate the given word problem into solvable algebraic equation.

Let "t" represent the number of tadpoles Joseph caught.

"Wendy caught nine times three more than Joseph caught" can be expressed as 9(t + 3)

Number of Wendy's tadpole = [tex] 9(t + 3) [/tex]

Given that half of Wendy's tadpole and also 6 times Joseph's tadpoles swarm away leaving Wendy with only 3, the following equation can be written:

[tex] \frac{9(t + 3)}{2} - 6t = 3 [/tex]

Step 2: solve for t using the equation created.

[tex] \frac{9(t + 3)}{2} - 6t = 3 [/tex]

Add 6t to both sides

[tex] \frac{9(t + 3)}{2} - 6t + 6t = 3 + 6t [/tex]

[tex] \frac{9(t + 3)}{2} = 3 + 6t [/tex]

Multiply both sides by 2

[tex] \frac{9(t + 3)}{2}*2 = (3 + 6t)*2 [/tex]

[tex] 9(t + 3) = 2(3 + 6t) [/tex]

[tex] 9t + 27 = 6 + 12t [/tex]

Collect like terms

[tex] 9t - 12t = 6 - 27 [/tex]

[tex] -3t = -21 [/tex]

Divide both sides by -3

[tex] t = 7 [/tex]

Joseph caught 7 tadpoles

Answer:

true

Step-by-step explanation:

it equals to

x1= -1

and

x2= 1

Answer:

Step-by-step explanation:

y=x²-1 is not a function for every value of y , x has more than one value

ex: if x=-1 , y=(-1)²-1 then y=0

if x=1 then y=0

Answer:

a^m-n

Step-by-step explanation:

If we have the expression m^a / m^n, we can use exponent rules to simplify this.

Exponent rules say that x^a / x^b = x^a-b. In this case, x is a, a is m and b is n, so the same rule applied here.

So a^m / a^m  will be equal to a^m-n

Answer:

The angular velocity is 8.38 radians per minute

Step-by-step explanation:

From the question,

It takes 45 seconds to complete a full revolution,

That is, 1rev/45secs

First, we will convert this to revolutions per minute (rev/min)

1rev/45secs = [tex]\frac{1 revolutions}{45 seconds} \times \frac{60seconds}{1minute}[/tex]

= 4/3 rev/min

Now, we will convert this to radians per minute (rad/min)

1 revolutions = 2π rad

4/3 rev/min = [tex]\frac{\frac{4}{3} rev}{min} \times \frac{2\pi rad}{1 rev}[/tex]

= 8.38 rad/min

Hence, the angular velocity is 8.38 radians per minute

Answer:

x + y - 10 = 0

Step-by-step explanation:

x + y - 10 = 10 -10

Move the constant to the left by adding its opposite to both sides

x + y - 10 = 0

The sum of two opposites equals 0

x + y - 10 = 0
