Which is simplified form of the expression (6-2•65)-3
Answer:Answer:
The simplified form of this is 6^-9
Step-by-step explatnation
In order to find this, we first complete the operation inside the parenthesis. In this case, since it is multiplication, we add the exponents.
6^-2 x 6^5 = 6^3
Now that we have the simplified inside we multiply exponents using the parenthesis.
(6^3)^-3 = 6^-9
Step-by-step explanation:
Solve for x.

Lana uses factoring by grouping to factor the polynomial 8x2y−10xy2+12x−15y. Her work follows, but the last two lines of work are missing.
Which answers correctly fill in the blanks?
Select two answers: one for blank 1 and one for blank 2.
Answer:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)
Step-by-step explanation:
The first step in factoring this polynomial is to find the biggest common factor in both numbers inside the parenthesis, and the second step is to find the biggest common factor of the 2 addents.
The other steps are invalid, either because they don't respect positive or negative signs, or that they just factor it wrong completely.
The only correct answer are:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)

A pet store sells mice, reptiles, and birds.
Let event A = A customer buys a mouse.
Let event B = A customer buys a bird.
What does P(A or B) = 0.25 mean in terms of this problem?
A. Buying a mouse and buying a bird are mutually exclusive events.
B. The probability that a customer buys neither a mouse nor a bird is
25%.
C. The probability that a customer buys both a mouse and a bird is
25%.
D. The probability that a customer buys either a mouse or a bird is
25%.
The correct answer is: The probability that a customer buys either a mouse or a bird is 25%.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
Given that, a pet store sells mice, reptiles, and birds,
Let event A = A customer buys a mouse.
Let event B = A customer buys a bird.
We need to tell that,
What does P(A or B) = 0.25 mean in terms of this problem,
So, here the statement given is saying that the 0.25 is the probability that a customer will buy either a mouse or bird,
Hence, the correct answer is: The probability that a customer buys either a mouse or a bird is 25%.

Answer:
5) y = -8x -4
6) y = 2x + 3
Step-by-step explanation:
Slope is rise over run. For the first problem, you went down 8 and over 1 to your next point. Going down means you have a negative slope. -8/1 is 8. Your y intercept is where the line meets the y axis. The line meets the y axis at -4.
The line meets a new point every time it goes over 1 and up 2. Rise over run means 2/1. The line goes up so the slope is positive. The line meets the y axis at 3
What is the first question you ask yourself when factoring a polynomial?
Which is the best estimate of 26 × 604?
Answer:
The answer is actually 18,000 because for 26 your rounding the nearest ten and for 604 you rounding the nearest hundred so it is 30 x 600 = 18,000
Step-by-step explanation:
The best estimation of 26 × 604 is 18000.
What is Number system?A number system is defined as a system of writing to express numbers.
We need to find estimate of 26 × 604
Approximating a quantity to the required accuracy is known as estimation. This estimation we can do by rounding off the numbers involved in the calculation and get a rough answer.
Now let us round off the number 26 to the nearest tenths.
26 is rounded to 30.
604 is round off to the nearest hundredth which is 600.
Now let us multiply 30 with 600 to get the estimated value of 26 × 604.
30×600
18000
Hence the best estimation of 26 × 604 is 18000.

Find an
equation for the perpendicular bisector of the line segment whose endpoints
e (-3, -8) and (5,-4).
are
Answer:
[tex]y=-2x-4[/tex]
Step-by-step explanation:
Perpendicular Bisector
The bisector of a segment defined by points (x1,y1) and (x2,y2) must pass by the midpoint of the segment.
The midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The endpoints of the segment are (-3,-8) and (5,-4), thus the midpoint M is:
[tex]\displaystyle x_m=\frac{-3+5}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{-8-4}{2}=-6[/tex]
Midpoint: M(1,-6)
Let's find the slope of the given segment. The slope can be calculated with the formula:
[tex]\displaystyle m_1=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\displaystyle m_1=\frac{-4+8}{5+3}=\frac{1}{2}[/tex]
If the bisector is also perpendicular, its slope m2 and the slope of the segment m1 must comply:
[tex]m_1.m_2=-1[/tex]
Solving for m2:
[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{\frac{1}{2}}=-2[/tex]
Once we have the slope -2 and the point through which our line must pass (1,-6), we compute the equation in its point-slope form:
[tex]y-y_o=m(x-x_o)[/tex]
[tex]y-(-6)=-2(x-1)[/tex]
Operating
[tex]y+6=-2(x-1)[/tex]
[tex]y+6=-2x+2[/tex]
Rearranging
[tex]\boxed{y=-2x-4}[/tex]

Raleigh went to a gaming arcade for his birthday. His parent gave him $55 to spend. He purchased $14.25 in food and drinks, and put the rest of the money on the gaming arcade. Each Game in the arcade cost $1.25. Write a linear inequality to represent how many games g Raleigh can play in the arcade
Answer:
Step-by-step explanation:
Let [tex]g[/tex] denotes number of games that Raleigh can play in the arcade.
Cost of 1 game = $1.25
Cost of [tex]g[/tex] games = [tex]\$1.25g[/tex]
Amount spent in food and drinks = $14.25
Total amount spent by Raleigh = [tex]14.25+1.25g[/tex]
Also, amount with Raleigh = $55
So, the inequality is [tex]14.25+1.25g\leq 55[/tex]
Divide the inequality by 5
[tex]2.85+0.25g\leq 11[/tex][tex]2.85+0.25g\leq 11[/tex]
