Negative 6 minus (negative 1)
Negative 6 minus 1
Negative 5 minus (negative 1)
Negative 5 minus 1
The expression that is the representation of the number of available tiles is (a) -6 - (-1)
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to interpret the representation of the tiles?The representation of the tiles is given as
6 negative tiles1 tile is crossed out.The above representation of tiles implies that:
Total number of tiles = 6All tiles are negativeOne of these negative tiles is crossed outThe representation of the tiles is
Available tiles = Total number of tiles - (The number of tiles crossed out)

Let f(x)=2 x²+8 and g(x)=x-3 . What are f+g and f-g ? What are their domains?
Domain of f + g ( x) = R and f - g ( x) = R
Given :
F(x) = 2x^2 + 8 and g(x) = x-3
From this, we get to know that f(x) and g(x) assume real values for all values of x.
Hence, domain (f)= Real(R) and domain (g)= real ( R ) .
Therefore D (f) and D(g) are Real Number
Now,
A > (f + g ) : R ----> R is given by (f + g) (x)
= f(x) + g(x) = 2x^2 + 8 + x- 3
= 2x^2 + x + 5
Hence, domain ( f + g ) = Real ( R )
B > (f – g) : R---> R is given by ( f-g ) (x)
= f(x) – g(x) = 2x^2 + 8 – ( x – 3)
= 2x^2 -x + 11
Hence, domain ( f - g ) = Real ( R ) .

find the value of k so that the point A lies on the line given by the equation.
A(2,1), 3x+ky=8
The value of K is 2 so that the point A lies on the line given by the equation A (2,1), 3x+ky=8.
Given: Equation is 3x+ky=8
Points A (2,1)
We need to determine the value for K
3x+ky=8 — 1 (Take as equation 1)
Substitute the points in equation 1
So, we take x = 2 and y = 1
3(2) +k (1) = 8
6+k = 8
k = 8 - 6
k = 2
When graphing points on a coordinate plane, it is often helpful to find the value of k that makes the point lie on a line. For this problem, k = 2 so that A (2,1), 3x+ky=8.
Hence, the value of K is 2 so that the point A lies on the line given by the

What is the probability of guessing all of the correct answers?
P(correct) = _______
Since each response is distinct, the odds of correctly predicting each response is 1/3× 1/3× 1/3, or 1/27.
Probability is the ability to happen. The occurrence of random events is the subject of this branch of mathematics. The value is expressed as a number between 0 and 1.
For instance, when a coin is tossed into the air, a Head or Tail are two possible results.
Hence, the term "probability" is most commonly used to refer to the likelihood that a specific event (or group of events) will occur, either as a linear scale from 0 (impossibility) to 1 (certainty) or as a percentage between 0 and 100%. Statistics is the study of events subject to probability.

The probability of getting a total of more than 4 is 5/6.
What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.So, formula: P = favorable events/total events
Total outcomes = 36Favorable outcomes (sum more than 4) = 30(Refer to the image attached below)

For each annual rate of change, find the corresponding growth or decay factor.+ 500%
The corresponding growth factor of +500% is 6
The formula for the annual rate of change is
1 ± r (1)
where r = rate of change
and ± sign depends upon whether it is a growth or decay factor. If it is growth factor then it is plus sign otherwise negative sign.
According to the question we have been given the growth that is +500%. Since there is plus sign therefore it is a growth factor.
Thus, r = + 5
Putting this value in equation (1) we get

The will meet after 2.5 hour.
To solve for distance use the formula for distance d = st, or distance equals speed times time.
distance = speed x time
Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.
distance = rate x time
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
speed = distance/time
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
time = distance/speed
let say they will meet after time t.
distance covered by first boat = velocity of boat × time= 8.5t
distance covered by second boat= 5.5t
distance between both boats = 35km.
by equating both the distance
35km = 8.5t+5.5t
35km = 14t
t= 35÷14 =2.5 hour= 9020.618 seconds.
