Answer:

12 pencils

Step-by-step explanation:

let no. of pencils bought be x.

54 - 0.75x - 2.50 = 42.50

9 = 0.75x

x = 12

What is the solution to the inequality <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bf%7D%7B2%7D" id="TexFormula1" title="\frac{f}

tester [92]

The solution of inequality $\frac{f}{2} - 19 < 47$ is f < 132

Solution:

Given that we have to find the solution of inequality

These things do not affect the direction of the inequality:

Add (or subtract) a number from both sides.

Multiply (or divide) both sides by a positive number.

Simplify the sides

Given inequality is:

$\frac{f}{2} - 19 < 47$

Add 19 to both sides of equation

$\frac{f}{2} - 19 +19 < 47 + 19\\\\\frac{f}{2} < 47 + 19\\\\\frac{f}{2} < 66$

Multiply both the sides of inequality by 2

$\frac{f}{2} \times 2 < 66 \times 2\\\\f < 132$

Thus the solution to given inequality is f < 132

Find the missing side of the triangle. A. 321−−−√ yd B. 221−−−√ yd C. 338−−√ yd D. 21−−√ yd

antoniya [11.8K]

Answer:

$x = \sqrt{221} yd$

Step-by-step explanation:

Use Pythagorean theorem to find x.

Thus, the sum of the square of the lengths of two legs of a right triangle equal the square of the hypotenuse, which is the longest side.

Thus,

$x^2 = 11^2 + 10^2$

$x^2 = 121 + 100$

$x^2 = 221$

$x = \sqrt{221} yd$

The equation of the parabola that similar to f(x) = $7x^2$ but the vertex is (3, 5) in the standard form is y = $7(x-3)^2$ + 5

The equation of the parabola

f(x) = $7x^2$

The standard vertex form of a parabola is

y = $a(x-h)^2$ + k

The coordinates of the vertex of a parabola = (3, 5)

Where (h, k) is the coordinates

From the given function of the parabola f(x) = $7x^2$

The value of a = 7

Substitute the values in the vertex form of a parabola

y = $7(x-3)^2$ + 5

Hence, the equation of the parabola that is similar to f(x) = $7x^2$ but the vertex is (3, 5) in the standard form is y = $7(x-3)^2$ + 5
