Cade and Tyce both tried to find the missing side of the right triangle. A right triangle is shown. The legs are labeled 6 and 9

. A right angle is labeled in between them. Cade's Work Tyce's Work a2 + b2 = c2 a2 + b2 = c2 62 + b2 = 92 62 + 92 = c2 36 + b2 = 81 36 + 81 = c2 b2 = 45 117 = c2 Square root b squared equals square root 45. Square root 117 equals c squared. b ≈ 6.71 cades answer 10.82 ≈ c tyce answer Is either of them correct? Explain your reasoning.

Step-by-step explanation:

Two legs of the right triangle are 6 and 9. We can find its third side as follows :

a^2+b^2=c^2

The above is called Pythagoras theorem and it is applicable for a right angled triangle.

a,b and c are base, perpendicular and hypotenuse respectively

c is the third side

So,

c^2=6^2+9^2\\\\c=\sqrt{117} \\\\c=10.816\approx 10.82

Hence, Cade and Tyce both are correct. The length of the missing side is 10.82

Answer:

Tyce's work is correct because he follows all the steps correctly. But Cade's did it wrong because he put the value of the B in C.

Step-by-step explanation:

1.

     A² + B² = C²

-------------------------------------------------- -------------------------------------------------- ------

2.

     6² + 9² = C²

-------------------------------------------------- -------------------------------------------------- -----

3.

    36 + 81 = 117 or 10.82

Find the solution to the following system using substitution or elimination:​
raketka [301]

Answer:

B) (3,1)

Step-by-step explanation:

y = -2x + 7

y = 3x - 8

3x - 8 = -2x + 7

combine like terms:

5x = 15

divide both sides of the equation by 5:

x = 3

y = 3(3) - 8 = 1

What does initial value mean?<br><br> (The topic matter is linear functions)
vagabundo [1.1K]
Initial value can mean many things, but what I believe it means in this area is the value that you start with (obviously), so in the equation (y=mx+b), the initial value is the b. It is where the line intercepts the y-axis, and that is your initial value, I believe!
I hope this was helpful and answered your inquiry! If you have any further doubts or questions, please let me know so that I can help you!

PLEASE HELP..... I WILL GIVE BRAINLIEST!!
Yakvenalex [24]
For the first part:

Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:

12+12+12=3(12)

With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:

19+19=2(19)

So, her total is:

3(12)+2(19)

If you subtract 3 from the total, then the expression is:

3(12)+2(19)-3=36+38-3=71

For the second part:

If she's paying 3 less for each shirt, then the cost of 3 shirts will become:

(12-3)+(12-3)+(12-3)=3(12-3)

In the same fashion, for the two jeans:

(19-3)+(19-3)=2(19-3)

So the expression for the total cost is:

3(12-3)+2(19-3)=36-9+38-6=59

For number three:

The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.

For number four:

If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).

So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.
