Answer:
(3 +/- i*sqrt(151) / 20 (no real solutions)
Step-by-step explanation:
10x^2 - 6x + 4 = -3x
Add 3x to both sides
10x^2 - 6x + 4 + 3x = -3x + 3x
10x^2 - 6x + 4 + 3x = 0
Add like terms
10x^2 - 3x + 4 = 0
We have to use quadratic formula to find the answers
For this equation, a = 10, b = -3 and c = 4
Note: +/- is plus or minus
Quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / 2a
x = (-(-3) +/- sqrt(-3^2 - 4(10)(4))) / 2(10)
x = (3 +/- sqrt(9 - 160)) / 20
x = (3 +/- sqrt(-151) / 20
x = (3 +/- i*sqrt(151) / 20
if there's a "-" sign inside a square root, it will give you an imaginary number.
Example:
-sqrt(9) = -3
sqrt(-9) = 3i (first you will ignore the "- " sign, then square the number. After finding the square root, take that '-' sign and turn it to an "i")
So for sqrt(-151), 151 is not a perfect square, so you will get a decimal number. Leave it as it is:
sqrt(151). We can't forget about the "-". Turn the minus into a sign.
It will be i*sqrt(151)
Imaginary numbers can't be simplified, so this is the answer.
(3 +/- i*sqrt(151) / 20

What is an equation of the line that contains the point (0, -5) and a slope of 1/4
Answer:
y=1/4x-5
Step-by-step explanation:
Answer:
y = 1/4x - 5
Step-by-step explanation:
y = mx + b is the equation of a straight line.
m = slope, b = y intercept. (y intercept is the point where the line of the graph crosses the y axis)
(0, -5) is the y intercept (if you were to graph this point, it would be on the y axis, fitting the previous description)
the slope is 1/4
replace each variable in the equation, and you get:
y = 1/4x - 5

Find the measure of MN. please help!!!!
Given:
A circle with center O.
[tex]m\angle MOP=45^\circ, m\angle PON=85^\circ[/tex].
To find:
The measure of arc MN.
Solution:
We know that,
[tex]m\angle MON=m\angle MOP+m\angle PON[/tex]
[tex]m\angle MON=45^\circ+85^\circ[/tex]
[tex]m\angle MON=130^\circ[/tex]
The central angles in equal to the measure of the corresponding arc.
[tex]Arc(MN)=m\angle MON[/tex]
[tex]Arc(MN)=130^\circ[/tex]
Therefore, the measure of arc MN is 130 degrees.

What is 4/9 x 5/7 x 1/2
Answer:
0.16
Step-by-step explanation:
4*5*1=20
9*7*2=126
20/126=10/63
Answer:
10/63
Step-by-step explanation:
First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.

A house is losing value at a rate of 5.4% per year. In 2009, the house was worth $331,000. Find the value of the house in 2021.
Answer:
$169803
Step-by-step explanation:
Given data
rate of decrease = 5.4%
time = 2009-2021= 12years
P= $331,000
Let us apply the compound interest formula
A=P(1-r)^t----------------note the minus sign because this is a decrease
A= 331000(1-0.054)^12
A= 331000(0.946)^12
A= 331000*0.513
A=$169803
Hence the value in 2021 is $169803
Explain two different ways to find a new value after an original value is increased by 30%.
Answer:
Frequently, we know the new amount and the percent change and need to know the original amount. We found that a $600 TV on sale for 30% off, cost $420 on sale. We might think, that to find the original cost of the TV that has a sale price of $420 after a sale of 30% off, we could just take 30% of the $420 cost and add it back to the $420 to find the original cost.
30% of $420 is 0.30($420) = $126 and $420 + $126 = $546.
Or, 130% of $420 is 1.3($420) = $546.
Notice that this is not the $600 original list price with which we started.

Step-by-step explanation:
Mr. Bayless invests $3500 in a savings plan. The savings account pays an
annual interest rate of 4.75% on the amount he put in at the end of the
year. How much will Mr. Bayless earn if he leaves his money in the savings
plan for 8 years and how much money will be in his savings plan at the end
of 8 years?
Answer:
Interest = $1330
Amount = $4830
Step-by-step explanation:
Given
Principal = $3500
Rate = 4.75%
Time T = 8 years
Interest =PRT/100
Interest = 3500*4.75*8/100
Interest = 35*4.75*8
Interest = $1,330
Hence the interest earned by Mr. Bayless is $1,330
Amount after 8years = Principal + Interest
Amount after 8years = 3500+1330
Amount after 8years = $4830
Hence the amount after 8years is $4830

Explain how to use the distributive property to simplify: -2(x + 5) ?
Answer:
-2x-10
Step-by-step explanation:
Distributive Property is basically a term for opening parentheses. So, in your case -2(x+5) we would multiply x and 5 by -2. X times -2 is -2x and 5 times negative 2 is -10. -2x-10 would be your final answer.
[tex]\huge\bold{ANSWER:}[/tex]
-2x-10
[tex]\bf{EXPLANATION:[/tex]
Hi there!
Here's what the Distributive Property states:
a(b+c)=ab+ac
So, we take a number outside the parentheses, and "distribute" it.
In this case, we should distribute -2:
-2(x+5)
-2x-10 (a negative times a negative is a positive)
