<h3>Answer: 3/4</h3>

=========================================================

Explanation:

We'll use this formula

a & b/c = (a*c + b)/c

to convert from a mixed number to an improper fraction.

John's mixed number converts to

a & b/c = (a*c + b)/c

6 & 3/4 = (6*4 + 3)/4

6 & 3/4 = 27/4

Do the same for Kerry's string

a & b/c = (a*c + b)/c

7 & 1/2 = (7*2 + 1)/2

7 & 1/2 = 15/2

We'll subtract those results to find the difference between them.

15/2 - 27/4 = 30/4 - 27/4 = (30-27)/4 = 3/4 is the final answer

Kerry's string is 3/4 of an inch longer compared to John's string.

Answer:

Step-by-step explanation:

Length of Kerry string = 7(½) = 15/2

Length of John string = 6(¾) = 27/4

15/2 - 27/4

30 - 27/4

3/4

Given the diagram below, find X. The diagram IS<br> 40°<br> x - 15°<br> X =<br> degrees.

Crank

Answer:

X=65°

Step-by-step explanation:

Both angles combined is a right angle as indicated by the small square drawn on it, a right angle is always 90° therefore

(x-15°)+40°=90°

combine like terms

x+25°=90°

subtract 25° from each side

x=65°

Jackson has a gift card for $120 to use at a department store. he wants to purchase 2 shirts and 3 pairs of pants with his gift

mylen [45]

The domain of this relationship can be defined as,

0 ≤ x ≤ 60

The range of this relationship can be defined as,

0 ≤ y ≤ 40

Definition of Domain and Range

The set of all the possible input values for which the provided function is defined is termed as the domain of that function.

The set of all the possible values that a given function can generate as an output is termed as the range of that function.

Forming the Relation

It is given that,

Jackson wants to purchase 2 shirts and 3 pairs of pants with his gift card

x represents the cost of the shirts and y represents the cost of the pants

The limit of the gift card = $120

Thus, the relation formed is given by,

$2x + 3y \leq 120$

Domain and Range of the Given Relation

We have,

$2x + 3y \leq 120$

⇒ $2x \leq 120$

⇒ $x\leq60$

Thus, the domain is given by,

⇒ $0\leq x\leq 60$

Similarly,

$3y\leq 120$

⇒ $y\leq 40$

Thus, the range is given by,

⇒ $0\leq y\leq 40$

Which functions have graphs that are steeper than the graph of f(x)=−3x^2?

netineya [11]

Answer:

g(x)=−4x^2 and m(x)=4x^2

Step-by-step explanation:

A horizontal stretch or shrink happens when you multiply the parent function (in this case f(x) = x²) by a number. If this number is between 0 and 1, the graph will be stretched horizontally. If this number is greater than 1, the graph will be shrunk horizontally. If the number is between -1 and 0, the graph will be stretched horizontally and flipped; if the number is less than -1, the graph will be shrunk horizontally and flipped.

The graphs that are horizontally shrunk are steeper than the others. This is m(x)=4x^2 and g(x) = -4x^2.
