Answer:
y = -5x + 15
Step-by-step explanation:
10x + 2y = 30
Subtract 10x from both sides.
2y = -10x + 30
Divide both sides by 2.
y = -5x + 15

Determine whether the distribution represents a probability distribution.
Answer:
No, the given distribution does not represents a probability distribution.
Step-by-step explanation:
In a probability distribution the sum of all the probabilities in a discrete probability distribution must add up to 1 and each individual probability can never be negative or greater than.
Here, P(3) = -3, which is negative, so, the given distribution does not represents a probability distribution.

emma's mother started a college fund of emma's 3rd birthday. She deposited $4,500 into an investment account that yields an interest rate of 7.5% compounded annually. If no additional deposits or withdrawals are made, how much will this investment account be worth when emma turns 18 years old?
Answer:
The interest is $1350 and the amount is $5850.
Step-by-step explanation:
STEP 1: Find an interest by using the formula I = P*I*T, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example P = $4500, i = 7.5% and t = 4 years, so
4500*0.075*4
I = 1350
STEP 2: Find an amount by using the formula .
Since P = $4500 and I = $1350 we have
$4500 + $1350 = $5850
Peter made five less than triple as many cookies as Mark did. Let c represent the number of cookies Mark made. Write an expression to determine the number of cookies Peter made
Answer: 3c - 5
Step-by-step explanation:
Since c represent the number of cookies that Mark made. We are then informed that Peter made five less than triple as many cookies as Mark. This will be:
= (3 × c) - 5
= 3c - 5
The expression is 3c - 5

Find the amount erica owes at the end of 6 years if $60000 is loaned to her at a rate of 4% compounded monthly
Answer: $76,244.51
Step-by-step explanation:
You need to use the compound interest formula here.
First of all however, you need to convert the terms to monthly figures because the interest is compounded monthly.
4% in months = 4 / 12 = 4/12%
6 years = 6 * 12 = 72 months
Now use the compound interest formula:
= Amount * (1 + rate) ^ number of years
= 60,000 * ( 1 + 4/12%) ⁷²
= $76,244.51

Diego is solving the equation x^2-12x = 21
Answer:
The solutions to the quadratic equations will be:
[tex]x=\sqrt{57}+6,\:x=-\sqrt{57}+6[/tex]
Step-by-step explanation:
Given the expression
[tex]x^2-12x\:=\:21[/tex]
Let us solve the equation by completing the square
[tex]x^2-12x\:=\:21[/tex]
Add (-6)² to both sides
[tex]x^2-12x+\left(-6\right)^2=21+\left(-6\right)^2[/tex]
simplify
[tex]x^2-12x+\left(-6\right)^2=57[/tex]
Apply perfect square formula: (a-b)² = a²-2ab+b²
i.e.
[tex]x^2-12x+\left(-6\right)^2=\left(x-6\right)^2[/tex]
so the expression becomes
[tex]\left(x-6\right)^2=57[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
solve
[tex]x-6=\sqrt{57}[/tex]
add 6 to both sides
[tex]x-6+6=\sqrt{57}+6[/tex]
Simplify
[tex]x=\sqrt{57}+6[/tex]
also solving
[tex]x-6=-\sqrt{57}[/tex]
add 6 to both sides
[tex]x-6+6=-\sqrt{57}+6[/tex]
Simplify
[tex]x=-\sqrt{57}+6[/tex]
Therefore, the solutions to the quadratic equation will be:
[tex]x=\sqrt{57}+6,\:x=-\sqrt{57}+6[/tex]

What is the value of
h
if
4
h
+
5
=
106
?
Answer:
25.25
Step-by-step explanation:
4h + 5 = 106
4h = 101 ^ Subtraction property of equality
101 ÷ 4 = 25.25
h = 25.25
Answer:
h = 25.25
Step-by-step explanation:
4h + 5 = 106
Subtract 5 from both sides to isolate the coefficient and variable:
4h = 101
Divide 4 to both sides to isolate the variable:
101 divided by 4 = 25.25
Checking my work:
Since h = 25.25, we would replace that number where h is
4(25.25) + 5 =
4(25.25) = 101
101 + 5 = 106
Therefore, the answer h = 25.25 is true
How to find the LCM (least common multiple) of two numbers
Step-by-step explanation:
The L.C.M of any numbers can be obtained by using two methods and they are :
Prime Factorization method Division methodThe steps for finding L.C.M of the given numbers by prime factorization method are mentioned below :
First of all , find the prime factors of each numbers.Take out the common prime factors.Also take out the other remaining prime factors.Multiply those all prime factors and obtain L.C.M if there is not any common prime factors , then their L.C.M is the product of the given numbers..The steps for finding L.C.M of the given numbers by division method are mentioned below :
Arrange the given numbers in horizontal position.Thus , arranged numbers should be divided by a prime number. During this process , that prime number should divide any two or more given numbers.Repeat the process till you get prime number as quotient for each number.The product of all prime factors and last quotients is L.C.M( According to me , Prime factorization method is kinda easy )
Example : L.C.M of 20 and 24
[tex] \underline{ \text{USING \: PRIME \: FACTORIZATION \: METHOD}} : [/tex]
20 = 2 × 2 × 5
24 = 2 × 2 × 2 × 3
L.C.M = Common factors × Remaining factors
= 2 × 2 × 5 × 2 × 3
= [tex] \boxed{ \text{120}}[/tex]

HELPPPPPPPPPPPPPPP asap
Answer:
a. 30 degrees
b. 60 degrees
c. 105 degrees
Step-by-step explanation:
Angle a is 30 degrees becuase it is congruent to the one right above it
Angle b is 60 degrees because the interior angles of a triangle always add up to 180. We know that angle a is 30 degrees and the angle with the mini square is a right angle, and right angles are always 90 degrees. Based on this information, we can subtract 90 from 180 followed by subtracting 30 from 90, which equals 60. Angle b is 60 degrees
Angle c is 105 degrees because a straight angle is 180 degrees. We know that one angle is 75, so we subtract 75 from 180 to get the difference. The difference is 105 degrees, which is also the measurement of angle c.
Hope this helps!

Lainey puts $600 into a GIC for 5 years. The GIC pays 6.2% interest, compounded monthly. How much interest has she earned after 5 years?
Answer:
FV= $819.03
Step-by-step explanation:
Giving the following information:
Initial investment= $600
Number of periods= 5*12= 60 months
Interest rate= 0.062/12= 0.0052
To calculate the future value of the investment, we need to use the following formula:
FV= PV*(1+i)^n
FV= 600*(1.0052^60)
FV= $819.03
