Answer:
Step-by-step explanation:
Note that x^2 - 6x + 9 = 0 can be rewritten as the square of a binomial:
(x - 3)^2
and the roots are found by setting this equal to zero and solving for x:
(x - 3)^2 = 0, or x - 3 = ±0, or x = 3 and x = 3
a) there are two equal roots: {3, 3}
b) the roots {3, 3} are rational
c) the roots {3, 3) are real
If you want to use the quadratic formula, proceed as follows:
1. Identify the coefficients of the quadratic: {1, -6, 9}
2. Find the discriminant b^2 - 4ac: It is (-6)^2 - 4(1)(9) = 36 = 36 = 0
As a general rule, if the discriminant is zero, the quadratic has two equal, real roots. These roots are rational: 3 can be rewritten as 3/1, which is a ratio.
This week at the farmer's market the price of oranges per pound has decreased by 20% compared to last week. If the price of oranges this week is $3.89, which equation would represent the price of oranges per pound last week, p?
Answer:
$4.8625
Step-by-step explanation:
$3.89 + 20%
$3.89 = 80%
$3.89 × ¼ = $0.9725
$0.9725 × 5 = $4.8625
what number is 6% of 850?
Answer:
51 is 6% of 850
Step-by-step explanation:
0.06*850
6 is 4% of what
number?
Answer:
150
Step-by-step explanation:
since 4 percent would have to be multiplied by 25 to get 100 you have to multiply 6 by 25. This comes out to 150. You can even check this by doing 150 times 0.04 which is 6 so we are correct!

PQRS is a parallelogram. Solve for x.
Plz help
Answer:
The opposite sides of a parallelogram are congruent, then
19x - 9 = 13x + 15 ( subtract 13x from both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4

Consecutive angles are supplementary, sum to 180° , that is
10y - 37 + 4y + 7 = 180
14y - 30 = 180 ( add 30 to both sides )
14y = 210 ( divide both sides by 14 )
y = 15
Then
∠ R = 10y - 37 = 10(15) - 37 = 150 - 37 = 113°
Then
∠ P = 113° ( opposite angles are congruent )

what is 3 3/4 dived by 2 5/8
Answer:
[tex]1 \frac{36}{84} [/tex]
simplified :
[tex]1 \frac{3}{7} [/tex]
Step-by-step explanation:
first, we turn them into improper fractions
[tex]3 \frac{ + 3}{ \times 4} \div 2 \frac{ + 5}{ \times 8} [/tex]
First, we multiply 3×4=12+3=15 the demoninator will remain the same.
2×8=16+5=21, denominator remains the same.
[tex] \frac{15}{4} \div \frac{21}{8} [/tex]
when it comes to division with fractions, you flip the right(direction)fraction then multiply.
[tex] \frac{15}{4} \times \frac{8}{21} [/tex]
15×8=120
4×21=84
[tex] \frac{120}{84} [/tex]
then turn in back into a mixed fraction.
[tex]1 \frac{36}{84} [/tex]
demoninator remains the same, how many times 84 goes into 120, which is once(whole number) and how many is left over (numberator)

Lisa works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this
week. Lisa sold a total of 110 CDs over the two weeks. Find the number of CDs she sold last week and the
number of CDs she sold this week.
Answer:
This week sales = 26
Last week sales = 84
Step-by-step explanation:
Let this week sales = x
Sales last week = 6 + 3x
Sales last week + this week = 110
x + (6 + 3x) = 110
x + 6 + 3x = 110
6 + 4x = 110
4x = 110 - 6
4x = 104
x = 26
This week sales = 26
Last week sales = 6 + 3(26) = 84

Please help me with this !
Answer:
a. 4 (or maybe like 3.5)
b. 6
Step-by-step explanation:
a. Going from x = 0 to x = 8, it is obvious that y goes down 4 or 4.5 units during this stretch. This gives an approximate slope of -3/8. With this in mind, it can be easily calculated that going the remaining distance from x = 8 to x = 10, the value of y will be approximately 4 or so.
b. A dot literally is right next to (6, 6).
Select all the expressions that are equivalent to
1/2(2).
Z+Z
Z/2
Z/Z
1/4 (z)+1/4 (z)
2(z)
Answer:
Step-by-step explanation:
An ellipse is defined as the locus of all points,the sum of whose from two given points is constant. Here z is a complex number whose distance from (1,0) and (−1,0) is constant. Hence the locus of z is an ellipse in the complex plane. Hence z will be all those points which lies on the ellipse with focus (−1,0) and (1,0).

Solve the system of equations
2x+3y= 6
x+y=4
(6,-2)
(-2,6)
(-3, 4)
(0, 2)
Answer:
Step-by-step explanation:
2x+3y= 6 ========================>>> 2x + 3y = 6
x+y=4 ===== times both sides by 2 =====>>> 2x + 2y = 8
==== subtract these two equations ==>> (2x - 2x) + (3y - 2y) = 6 - 8
0x + y = -2
y = -2 so if x + y = 4 plug in -2 where y was
x + (-2) = 4 add 2 to both sides
x = 6
(6,-2)
(-2,6)
(-3, 4)
(0, 2)
