Answer:
D. 2 1/4.
Step-by-step explanation:
First, convert both -5 1/4 and -7 1/2 into improper fraction. These would be -21/4 and -15/2.
-21/4 - (-15/2)
Two negatives in a row make a positive.
-21/4 + 15/2
Double both the numerator and denominator of 15/2 to make it have the same denominator as -21/4. This would 30/4.
-21/4 + 30/4
Put -21 + 30 over 4 to make it a single fraction.
(-21 + 30)/4
Add -21 and 30 to get 9.
9/4
Convert 9/4 into a mixed number: 2 1/4
The answer to -5 1/4 - (-7 1/2) is 2 1/4, which is D.

What is a quadratic equation? And how do you solve them?
Answers
Answer:
A quadratic equation is some thing like
(x+2)^2
or
(x+2)(x+5)
In order to solve them, the most basic method is the FOIL method
F-First
O-Outside
I-Inner
L-Last
So for example
(x+2)^2
Which is basically
(x+2)(x+2)
So the first is the 2 Xs
(x+2)(x+2)
x*x=x^2
The outer is the x and the 2,
(x+2)(x+2)
2*x=2x
Now the Inner which is the 2 and the x
(x+2)(x+2)
2*x=2x
And finally the last which is the 2 and the second 2
(x+2)(x+2)
2*2=4
Now add them all up
X^2+2x+2x+4
Combine like terms
x^2+4x+4
There you have it
Do the same with every other quadratic equation

Which graph represents the proportional relationship given by the rule "y is 3 times the value of x"?
Please answer fast less than 5 min
Answers
Answer:
The fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Step-by-step explanation:
Given the rule
''y is 3 times the value of x".
It means
y = 3x
comparing with the slope-intercept form of the line equation
y = mx+b
where y is the slope and b is the intercept
so,
The slope of y = 3x will be: m = 3
The y-intercept of y = 3x will be: b = 0
CHECKING THE 4TH GRAPH (THE RIGHT BOTTOM SIDE)
Taking two points
(0, 0)
(2, 6)
Finding the slope between (0, 0) and (2, 6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 0] / [2 - 0]
= 6 / 2
= 3
Thus, the slope of the line = m = 3
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = 3 and b = 0 in the slope-intercept form of linear function
y = mx+b
y = 3x+0
y = 3x
Therefore, the fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Answer:
It's the bottom right graph.

Choose all the problems that you will solve by regrouping. A. 65 – 56 = ? B. 28 – 15= ? C. 16 – 6 = ? D. 74 – 38 = ?
Answers
Answer:
(a) and (d) will be done by regrouping
Step-by-step explanation:
Solution will be done by regrouping if unit term of term which is subtracted is greater then the term which subtracts.
(a) 65 -56, since the unit term of 65 is 5 and of 56 is 6
as the unit terms of 56 is greater than unit term of 65
Thus solution will be done by regrouping
⇒ 65 -56 = 9
(b) 28 -15, since the unit term of 28 is 8 and of 15 is 5
as the unit terms of 28 is greater than unit term of 15
Thus solution will not be done by regrouping
⇒ 28 -15 = 13
(c) 16 -6, since the unit term of 16 is 6 and of 6 is 6
as the unit terms of 16 is equal to unit term of 6
Thus solution will not be done by regrouping
⇒ 16 -6 = 10
(d) 74-38 , since the unit term of 74 is 4 and of 38 is 8
as the unit terms of 38 is greater than unit term of 74
Thus solution will be done by regrouping
⇒ 74-38 = 36

Jamie bought a handbag for 20$, an umbrella for $5.99, and a scarf for $8.50. If the sales tax rate is 7% how much is the sales tax and the total cost of her purchase
Answers
Answer: $36.9043
Step-by-step explanation:
Given that :
Cost of handbag = $20
Cost of umbrella = $5.99
Cost of scarf = $8.50
Sales tax = 7% = 0.07
Sales tax = 0.07 * (20 + 5.99 + 8.50)
Sales tax = 0.07 * 34.49
Sales tax = $2.4143
Total cost of purchase :
Sales tax + cost of items
$2.4143 + $34.49
= $36.9043
