Solve algebraically:
Y = x^2 + 5x - 17
Y = x - 5

Answers

Answer 1
Answer:

Answer:

2

Step-by-step explanation:

What you could do is fill in 2 for the equation and y would equal -3 so for the first one it's like

y= 2^2 + 5(2) -17

y= 4 + 10 - 17 which turns into y= -3

In the second y it would be something like

y= 2 - 5 which would equal y= -3

so x=2

What dose 5h-2+9h equal explain☺

Answers

Start out by combining LIKE TERMS 
5h-2+9h 
in this case 9h and 5h are like terms so you would add both of those together.
9h+5h=14h
-2 has no like terms so we can't do anything with it our final answer would be:
14h-2

How do you solve
42 customers increased by 50%

Answers

First, determine what 50% of 42 is. 
42 x 0.50 = 21 (Note: 0.50 is 50% in decimal form).
Then, add 50% of 42 (Which is 21) to 42. 
42 + 21 = 63
So, if 42 customers increased by 50%, there are now 63 customers. 
Hope that helps!!
First you find half of 42, which is 21, then add 21 to 42, which is 63. I hope that helped!

Solve the equation for the letter L: V = LWH

Answers

LWH=V\qquad\text{divide both sides by}\ WH\neq0\n\n\boxed{L=(V)/(WH)}

Answer:

L = V / WH

Step-by-step explanation:

Solve for L: V = LWH

To solve, all you have to do is get L on its own on one side.

Because the only operation used in this equation is multiplication, only one operation is needed to solve it: division. Just divide both sides by WH to isolate L.

V / WH = LWH / WH

V / WH = L

y=4-2x and 4x+2y = 5 can be rewritten as:

 y = -2x + 4
2y = -4x + 5

Multiply all 3 terms of the first eq'n by 2:    2y = -4x + 8

Note that 2y = -4x shows up in both equations.  This is enuf info on which to conclude that the 2 lines have the same slope.

Triangle ABC has a perimeter of 22cmAB=8cm
BC=5cm
By calculations, deduce whether triangle ABC is a right angled triangle

Answers

ΔABC is not a right angled triangle.

Step-by-step explanation:

  • Step 1: Given perimeter of ΔABC = 22 cm, AB = 8 cm and BC = 5 cm. Find AC.

Perimeter = AB + BC + AC

⇒ AC = 22 - (8 + 5) = 22 - 13 = 9 cm

  • Step 2: Find whether the triangle is right angled using Pythagoras Theorem.

AC² = AB² + BC²

⇒ AC² = 9² = 81

⇒ AB² + BC² = 8² + 5² = 64 + 25 = 89

∴ AC² ≠ AB² + BC²

⇒ ΔABC is not a right angled triangle.
