PLEASE HELP!!! Write a quadratic equation if its roots are: [tex]\sqrt{3} -1/2[/tex] and [tex]\sqrt{3} +1/2[/tex]
Answer:
x²- √3 x +1/2
Step-by-step explanation:
To write a quadratic equation with roots only:
x² -(sum of the roots)x+(product of roots)
x²-((√3-1/2)+(√3+1/2)x + ((√3-1/2)(√3+1/2)
x² -(2√3)/2 + ( 9-1)/4
x²- √3 x +1/2

Why is thinking about the problem before you work important?
Answer: It's good to think about things before doing them because it is more thought out and you have a better chance of getting things correct whereas without thinking your most likely going to get it wrong. Without thinking through your options you are basically guessing the answer. I hope this helped you have a great day and god bless you :D
Graph the system below and write its solution. Y=1/2x-1
-2x+y=4
You can answer no solution or infinitely many
Answer:
x = -3.3333333
y = -2.666666
Step-by-step explanation:
y = 1/2 x - 1
y = 2x + 4 The second equation has the 2x moved to the right side. The y's must be equal so equation the two equations.
1/2x -1 = 2x + 4 Subtract 1/2x from both sides.
-1 = 2x - 1/2 x + 4 Combine
-1 = 1.5x + 4 Subtract 4 from both sides
-1 - 4 = 1.5x
- 5 = 1.5x Divide both sides by 1.5
-5/1.5 = x
x = - 3.333333
Now put x = - 3.333333 into either one of the two given equations. The first one will require one less step, but it does not matter.
y = 1/2 (- 3.3333333) - 1
y = - 1.6666666 - 1
y = -2.6666666

An investment company pays 7% compounded semiannually. You want to have $24000 in the future. How much should you deposit now to have that amount 5 years from now?
Answer: You should deposit about $17014 or little more
Step-by-step explanation:
use the compound interest formula.
A= p( 1 + r/n)^nt
Where A is the amount you will save over some years .
p is the principal or start up amount mostly known as the initial fee.
r is the interest rate represent by a decimal so 7% will be 0.07.
n is the number of times the interest is being applied annually. Semiannually means twice. So n will be 2.
T is the time the money will elapsed. So in 5 years the money will elapse. Now input the values into the formula and solve for p the principal.
24,000 = p( 1 + 0.07/2)^2*5
24,000= p( 1 + 0.035)^10
24000 = p( 1.035)^10
24000 = p( 1.41059876062) Divide both sides by 1.41059876062
p = 17104
Which means you should deposit about $17014 or little more

Can someone please please pleaseee helppp
Step-by-step explanation:
Hey there!!!
Here,
The point is, (-3,1).
Using one point formula.
(y-1)= m(x+3)....1st equation.
It has said that it is also perpendicular to the line y = 1/3x + 2 .......2nd equation.
Now, the equation with y = mx + c.
We get slope (m2) = 1/3.
Now,
As per the condition of perpendicular lines,
[tex]m1 \: \times m2 = - 1[/tex]
[tex]m1 \times \frac{1}{3} = - 1[/tex]
Simplifying them we get,
m1 = -3.
Therefore the slope is -3.

NEED HELP ASAP!!! Which of the following correctly uses absolute value to show the distance between −70 and 15? Question 6 options: 1) |−70 − 15| = |−85| = −85 units 2) |−70 + 15| = |−55| = 55 units 3) |−70 − 15| = |−85| = 85 units 4) |−70 + 15| = |−55| = −55 units
Answer:
3) |−70 − 15| = |−85| = 85 units
Step-by-step explanation:
Absolute value ignores negative values so the equation when finding the distance between −70 and 15 is 70 + 15 which equals 85.

Division first:
-2/5 / 8/15
When dividing two fractions flip
The second one over and multiply:
-2/5 x 15/8 = (-2x15)/(5x8) = -30/40 = -3/4
Now you have:
2-3/4-3/4
2-3/4 = 1 1/4
1 1/4 - 3/4 = 1/2
The answer is 1/2
What is the missing statement and the missing reason in step 5? A 2-column table with 7 rows. Column 1 is labeled statements with the entries measure of angle A D E = 60 degrees and measure of angle C D F = (3 x + 15) degrees, angle A D E and angle C D F are vertical angles, angle A D E is-congruent-to angle C D F, measure of angle A D E = measure of angle C D F, question mark, 45 = 3 x, and, 15 = x. Column 2 is labeled reasons with the entries given, definition of vertical angles, vertical angles congruent, definition of congruency, question mark, subtractive property, division property. Statement: 60 = 3x + 15; Reason: substitution Statement: x = 15; Reason: subtraction property of equality Statement: 60 = 3x + 15; Reason: transitive property Statement: x = 15; Reason: subtraction and division properties of equality
Answer:
Statement: 60 = 3x + 15; Reason: substitution
(aka A)
Step-by-step explanation:
The missing statement and the missing reason in step 5 is;
Statement: 60 = 3x + 15; Reason: substitution
Here,
We have to find the missing statement and missing reason.
What is Substitution method?
Substitution method is algebraic method to solve the linear equations .
Now,
Column 1 and column 2 are labeled here as;
Angle A D E = 60 degrees ( entries given)
Angle C D F = (3 x + 15) degrees
Angle A D E and Angle C D F are vertical angles. (definition of vertical angles)
Angle A D E is-congruent-to Angle C D F. ( definition of congruency)
Measure of angle A D E = Measure of angle C D F.
⇒ 60 = 3x + 15 ( substitution )
⇒ 45 = 3 x ( subtractive property )
⇒ 15 = x ( division property )
Hence, The missing statement and the missing reason in step 5 is;
Statement: 60 = 3x + 15; Reason: substitution

absolute value of 100
Answer:
100
Step-by-step explanation:
Think of the absolute of a number as the distance from that number to zero on the number line. The distance from 100 to 0 on the number line is 100, so absolute value of 100 is 100. Notice that -100 is also at a distance of 100 from zero, so |-100| = 100.
|100| = 100
