Evalute The Expression 2b+5=2
Answer:
b = -3/2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
2b + 5 = 2
Step 2: Solve for b
Subtract 5 on both sides: 2b = -3Divide 2 on both sides: b = -3/2Find the constant of proportionality in the equation below. Y=1/8x
Answer:
1/8
Step-by-step explanation:
y =kx where k is constant
so k = 1/8
I need help pls asap
Answer:
Step-by-step explanation:
first we are told that side and ae and a f are the same
so that means one side of each triangle is the same
next we are told that that the lines coming off of those sides are both right angles. so we know these are both right triangles
and b/c both of those angle are right angles... the sides ab and ac have to also be the same length.. or the angle could not be a right angle
therefore since two sides are the same length then all 3 must be the same lengths
and b/c all three are the same these two triangles are the same .. congruent

How many times larger is the area of Polygon DDD than the area Polygon CCC?
Answer: You simply square the linear scale factor 6 and we get 6^2 = 6*6 = 36
You can think of a square with sides of 2 by 2, so the area is 4 If you multiply each dimension by 6, then the square is now 12 by 12 and the new area is 144.

Mrs. Canale’s class is selling frozen pizzas to earn money for a field trip. For every pizza sold, the class makes $5.35 They have already earned $182.90 but they need $750 How many more pizzas must they sell to earn $750? Write and solve an equation for this scenario. If you can, can you show the equation you used.
Answer:
106 pizzas
Step-by-step explanation:
The number of more pizzas required to sell for earning $750 is as follows:
Given that
Already earned amount = $182.90 =x
Need to achieved = $750 = y
So, the remaining amount would be
= y - x
= $750 - $182.90
= $567.10
For every pizza sold, it make for $5.35
So, the number of pizza would be
= $567.10 ÷ $5.35
= 106 pizzas

Marie pays $2.50 for 5 pecils. Use the drop down menu to explain how to determine and use constant of proportionality, in dollars per pencil, that relates these values
Answer:
$0.5
Step-by-step explanation:
Given data
Cost of 5 pencils= $2.50
Required
The cost per pencil
The cost per pencil is
Cost of 5 pencils divided by 5
=2.5/5
=$0.5
This is the constant of proportionality
For any number of pencils x
The cost is
Cost =0.5x
Hence the cost of one pencil is $0.5
IS THERE AN OUTLIER? IF SO WHAT IS IT? 3/4/6/7/9/10/17/28/16
Answer:
I'm pretty sure it's 16, but my initial thought was 17 from a pattern, but 16 just seems so random.
The pattern was the first number plus the number 2 times before it.
Ex: 3 + 4 = 7
3 + 6 = 9
3 + 7 = 10

(40 divided by 2) x 30 =600m^2
Step-by-step explanation:
semi perimeter(s) = (30+40+50)/2
= 60
a=30 b=40 c=50
area = √s(s-a)(s-b)(s-c)
= √60(60-30)(60-40)(60-50)
= √60×30×20×10
=√360000
=600

5. (10.607, 14.229)
6. (-1.586, -0.764)
7. (4, 5.211)
8. (-3.5, -2.342)
Step-by-step explanation:
Given:
the attached function definitions and intervals
Find:
the minimum and maximum on the given interval
Solution:
In a couple of cases, the coefficient of x is negative, indicating the basic square root function has been reflected over the y-axis. That will put the maximum at the left end of the interval, instead of the right end, where it would otherwise be.
__
5. minimum: f(3.5) = 5√(3.5+1) +1 = 5√4.5 +1 = 10.607
maximum: f(6) = 5√(6+1) +1 = 5√7 +1 = 14.229
__
6. minimum = f(-2) = √(-(-2)) -3 = √2 -3 = -1.586
maximum = f(-5) = √(-(-5)) -3 = √5 -3 = -0.764
__
7. minimum = f(-6) = 2√(3 -(-6)) -2 = 2√9 -2 = 4
maximum = f(-10) = 2√(3 -(-10)) -2 = 2√13 -2 = 5.211
__
8. minimum = f(0) = (1/2)√(0 +1) -4 = -3.5
maximum = f(10) = (1/2)√(10+1) -4 = (1/2)√11 -4 = -2.342

Jasmine is taking out a small business loan for her floral shop. She plans to apply for a $30,000 loan with a 5-year term and a 3.75% interest rate. She is unsure of her expected monthly profits, so she wants to know the benefit of a smaller loan. Using the loan amortization formula, how much money would Jasmine save over the life of the loan if she were to borrow $10,000 less?
Answer:
Monthly pay = int. rate / 12 months * cost of car after downpayment / (1-(1+ int. rate/12 months)^( - term length of loan )
Step-by-step explanation:
Just plug in your numbers:
M = 0.0375/12 * 30000/(1-(1+.0375/12)^60)
since 5 years is 60 months
