Answer:

y=17,x=15

Step-by-step explanation:

180-112=68

68/4=y=17

180-68=112

112-7=105

105/7=x=15

X^2-10x+27 in the form (x-a)^2+B​
Irina18 [472]

Answer:

(x-5)^2+2

Step-by-step explanation:

To convert between standard and vertex form, you have to complete the square (which, as a reminder, (a+b)^2 = a^2+2ab+b^2).

Since a^2 is x^2, and 2ab is -10x, then b must be -5, so b^2 is 25. Therefore, we add and subtract 25 from the expression:

(x-10x+25)+27-25

Then, we can make (x-10x+25) to (x-5)^2:

(x-5)^2+2

How do I do the bus stop method?
hichkok12 [17]
The bus stop method is just like division.
Ex
137÷5= 
1.) 5 goes into one zero times so there is a zero on top.
2.) 5 goes into 13 two times, so after the zero there is a 2.
3.) 5 goes into 37 seven times so there is a 7 after the 2.
4.) There is a 2 left and five can't go into school therefore that is a remainder.

A cone and a sphere have the same volume the base of the cone has a radius of 8 feet and the sphere has a radius of 6 feet what
jekas [21]

Step-by-step explanation:

Volume of Cone=

\frac{1}{3} \pi \: r {}^{2} h

Volume of Sphere=

\frac{4}{3} \pi \: r {}^{3}

Since VC = VS

\frac{1}{3} \times 3.14 \times 8 {}^{2}  \times h =  \frac{4}{3}  \times 3.14 \times 216

66.99h = 904.32

h = 904.32 ÷66.99

h= 13.5 feet

Write the quadratic function in vertex form: f(x) = 4x2 + 2x -5
Andrei [34K]
Please use " ^ " to denote exponentiation:  <span>f(x) = 4x^2 + 2x -5.  To find the vertex form of this equation, complete the square:

f(x) = 4x^2 + 2x                                           - 5
      = 4(x^2 + (2/4)x)                                         - 5
      =  4(x^2 + (1/2)x )                                  -5
      = 4(x^2 + (1/2)x + 1/16  ) - 4/16 - 5
      = 4(x+1/4) - 21/4    <= in vertex form

Here h= -1/4 and k = -21/4.  The vertex is at (-1/4, -21/4)</span>
