Find the X and Y Intercepts y=x^2-7x+12

y=x2−7x+12y=x2-7x+12

To find the x-intercept, substitute in 00 for yyand solve for xx.

(0)=x2−7x+12(0)=x2-7x+12

Solve the equation.

x=4,3x=4,3

To find the y-intercept, substitute in 00 for xxand solve for yy.

y=(0)2−7⋅0+12y=(0)2-7⋅0+12

Solve the equation.

y=12y=12

These are the xx and yy intercepts of the equation y=x2−7x+12y=x2-7x+12.

x-intercept: (4,0),(3,0)(4,0),(3,0)

y-intercept: (0,12)(0,12)

Sofia has an action figure collection. She keeps 185 of the action figures on her wall, which is 37% of her entire collection. W

Stolb23 [73]

Answer:

500 figures.

Step-by-step explanation:

We know that 185 figures is 37% of her entire collection.

Let c represent the total amount of figures.

Since 185 is 37% or 0.37 <em>of</em> her total collection, we can write the equation:

$0.37c=185$

Remember that the keyword <em>of</em> tells us it's multiplication.

Therefore, to find the number of figures in her total collection, divide both sides by 0.37:

$c=\frac{185}{0.37}$

Evaluate. Use a calculator. So:

$c=500$

Sofia's total collection has 500 figures.

Min wants to make 100 name tags with ribbon attached to them. Each name tag requires 5 centimeters of ribbon. She has 3.25 meter

Kisachek [45]

3.25 meters = 325 cm

325cm / 5 cm= 65 name tags with the ribbon she has.

She still needs 35 name tags, so 35 × 5 = 175cm cm.

She still needs 175cm of ribbon to make a total of 100 name tags.

If 3/5 of the certain length is 210m then 5/7 of length is

Mamont248 [21]

Answer:

250 m

Step-by-step explanation:

Let the total length be x m.

$\therefore \: \frac{3}{5} \times x = 210 \\ x = 210 \times \frac{5}{3} \\ x = 70 \times 5 \\ x = 350 \: m \\ \\ \frac{5}{7} \times x = \frac{5}{7} \times 350 = 5 \times 50 = 250 \: m$
