34 x 2 = 68

Or

34 + 34 = 68

Jessica used 2/3 yard of fabric to make a scarf. Can she make 2 of these scarves with 1 3/4 yards of fabric, and why?

Alex Ar [27]

Option 1

Jessica can make 2 scarves

yes, because the quotient of $1 \frac{3}{4} \div \frac{2}{3} \text { is } 2 \frac{5}{8}$

<u>Solution:</u>

Given, Jessica used $\frac{2}{3}$ yard of fabric to make a scarf.

We have to find can she make 2 of these scarves with $1\frac{3}{4}$ yards of fabric, and why?

Now, let us find number of scarves that can be made from available scarf

$\text { Number of scarves }=\frac{\text { avaiable scarf }}{\text { fabric required for } 1 \text { scarf }}$

$\begin{array}{l}{=\frac{1 \frac{3}{4}}{\frac{2}{3}}=1 \frac{3}{4} \times \frac{3}{2}} \\\\ {=\frac{4 \times 1+3}{4} \times \frac{3}{2}} \\\\ {=\frac{16+5}{8}=2 \frac{5}{8}}\end{array}$

We know that,

$2 \frac{5}{8}>2$ so we can make 2 scarves.

Hence, yes, we can make 2 scarves because quotient of $1 \frac{3}{4} \div \frac{2}{3} \text { is } 2 \frac{5}{8}$

So 1st option is correct

The function h(x) is a transformation of the square root parent function,

Setler [38]

The function h(x) is a transformation of the square root parent function,

f(x)=√x. The function is h(x) A: √x+5.

<h3>What is Transformations?</h3>

Transformations come in the form;

y =√(x-h) +k,

where h is responsible for left-right movements, and k is responsible for up-down movements.

From the graph, we can see that f(x) is simply the parent square root function, √x.

To translate a function right by p units and up by q units, the function becomes

g(x) = f(x -p) +q

(p, q) = (5, 0)

To get h(x), there is a translation of 5 units to the left, which can be represented by a value of h = -5.

h(x) = f(x + 5) +0

h(x) = √(x+ 5)

Hence, The function h(x) is a transformation of the square root parent function, f(x)=√x. The function is h(x) A: √x+5.

Solve x^2=2x+3 by factoring

solong [7]

The solution is x = 1 and x = -3

<em><u>Solution:</u></em>

Given that we have to solve the given equation by factoring

Given equation is:

$x^2=2x + 3\\\\x^2 - 2x - 3 = 0$

$\text{Consider the form } x^2+bx+c$

Find a pair of integers whose product is c and and whose sum is b

$\text{Compare } x^2-2x-3 = 0 \text{ with } x^2+bx +c\\\\\text{We get } b = -2 \text{ and } c = -3$

Now find, a pair of integers whose sum is -2 and product is -3

The integers that satisfies this condition is -1 and 3

When we add - 1 and 3 we get 2

When multiply -1 and 3 we get -3

Thus the pair of integers are -1 and 3

Write the factored form using these integers.

$(x-1)(x+3) = 0$

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0

Set the factors equal to 0

$x - 1 = 0 \text{ and } x + 3 = 0$

x = 1 and x = -3

Thus the solution is x = 1 and x = -3
