Hi! What is y = x^2 -4x +5 vertex form? Please explain how you got this answer. Thanks! :)
Anarel [89]

{x}^{2}  - 4x + 5 = 0 \\  {x}^{2}  - 4x =  - 5 \\   \\  { (\frac{b}{2} )}^{2}  = ( \frac{ - 4}{2} ) = ( { - 2})^{2}  = 4 \\  {x}^{2}  - 4x + 4 =  - 5 + 4 \\  {(x - 2)}^{2}  =  - 1 \\  {(x - 2)}^{2}  + 1
The last line is in vertex form, and can see the vertex is located at (2,1).

Katie went to a craft store to purchase the supplies she needed to make two types of jewelry, this table shows the costs of the
Pie

Answer:

cost of bracelet = 25*.05 +4*.45

cost of bracelets = 2(25*.05 +4*.45)

Step-by-step explanation:

One bracelet

Supplies needed:

25 beads and 4 charms

Each bead costs .05 and each charm costs .45

Cost of bracelet = number of beads * cost per bead + number of charms * cost per charm

cost of bracelet = 25*.05 +4*.45

cost of bracelet = 1.2 +1.8

                            =3.00


To make 2 bracelets

Cost of bracelets =2*( number of beads * cost per bead + number of charms * cost per charm)

cost of bracelets =2*( 25*.05 +4*.45)

cost of bracelets=2( 1.2 +1.8)

cost of bracelets = 2*3

cost of bracelets = 6

The quotient 250/ 5/8 tells about how far a sloth may move in one hour. How far can a sloth go in 90 minutes?
-BARSIC- [3]

250/5/8 = 250 × (8/5)

             = 400

So, a sloth may move 400 units per hour.

In other words, a sloth may move in 400 units per 60 minutes.

So, it will move \frac{400}{2} = 200 units per 30 minutes.

Therefore, it will move (400 + 200) units per (60 + 30) minutes.

Hence, in 90 minutes, the sloth may move 600 units.

What would x equal for these two?<br> 15/24 = x/3 &amp; 7/24 = 3/x<br><br> Thank you!!!
vesna_86 [32]

The first one you have \frac{15}{24}=\frac{x}{3} . To solve this you would multiply both sides by 3.

\frac{45}{24}=x

Then simplify by dividing the numerator and denominator by 3.

\frac{15}{8}=x (or in a mixed fraction 1\frac{7}{8})

The second one you have \frac{7}{24}=\frac{3}{x} . To solve this you would multiply both sides by x.

\frac{7}{24}x=3

Now you would divide both sides by \frac{7}{24}.

x=\frac{3}{\frac{7}{24}}

You now then multiply 3 by 24 and then divide by 7.

\frac{72}{7}

x=\frac{72}{7} (in a mixed fraction would be 10\frac{2}{7})
