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 & 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 $\frac{2}{7}$ )
