Jasmine will buy the same number of stamps every month to add to a stamp collection her grandfather gave her. The table shows the number of stamps Jasmine will have at the end of x months. How many stamps was Jasmine given, and how many stamps will she buy every month?
Jasmine was given 65 stamps, and she will buy 5 stamps every month.
Jasmine was given 60 stamps, and she will buy 65 stamps every month.
Jasmine was given 5 stamps, and she will buy 60 stamps every month.
Jasmine was given 60 stamps, and she will buy 5 stamps every month
Answer:
Option (4)
Step-by-step explanation:
If we draw a graph against x(Number of months) and y(Number of stamps),
We will get a straight line.
Let the equation of straight line be,
y = mx + b
Here, m = Stamps purchased per month
b = Jasmine was given stamps initially
From the table attached,
m = [tex]\frac{70-65}{2-1}[/tex] = 5 stamps per month
Therefore, equation of the line will be,
y = 5x + b
Since, a point (1, 65) lies on this line,
65 = 5(1) + b
b = 60
That means she was given 60 stamps initially.
Option (4) will be the answer.

If the measurement a is 69 and measurement a and b are complementary what is measurement b
Answer:
nice and
since it is complementary then a +b = 90
and substitution gives
69 + b = 90
b = 21
hope this helped and brainliest pls
Answer:
21
Step-by-step explanation:
I assume you are dealing with complementary angles.
m<a + m<b = 90
69 + m<b = 90
m<b = 90 - 69
m<b = 21

Which equation represents the axis of symmetry of the function y=-2x² + 4x -6?
Oy=1
Ox=1
Ox=3
Oy=3
Answer:
B
Step-by-step explanation:
We are given the quadratic function:
[tex]y=-2x^2+4x-6[/tex]
And we want to find its axis of symmetry.
First, the axis of symmetry is always a vertical line. Hence, it should be represented by x. Thus, we can eliminate choices A and D.
Next, the axis of symmetry for a quadratic is always the x-coordinate of its vertex point. The vertex for a quadratic equation is given by:
[tex]\displaystyle AOS=x=-\frac{b}{2a}[/tex]
For our function, a = -2, b = 4, and c= -6.
Therefore, our AOS is:
[tex]\displaystyle AOS=-\frac{4}{2(-2)}=-\frac{4}{-4}=1[/tex]
Hence, the equation of our axis of symmetry is x = 1.
B is our answer.
remember that percentages are based on one-hundredths. the value 100% one-hundredths or 100/100. the value of 50% equals 50/100 which can also be written as a decimal 0.50%. The value of 5% equals 5/100 or 0.005. Convert the following percentages into one-hundredths and then into a decimal: 75%, 20%, 0.8%?
Answer:
75/100, 20/100, 8/1000
0.75% , 0.2% or 0.20%, 0.008%

(T x 2) - 14 For t=46
Answer:
78
Step-by-step explanation:
Use PEMDAS for questions like these (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction) It gives an order in which you should solve the problem. In this case, put 46 instead of T to get (46*2)-14. If we look at PEMDAS, it shows that we need to do what is in the parenthesis first. So, 46x2=92. You get 92-14. Solve that and you get 78
Are the events "selecting a female" and "selecting a students who has brown eyes" independent?
Answer:
No, the events are not independent.
Step-by-step explanation:
Suppose that there are two events, A and B.
Such that first happens the event A and then the event B.
If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.
In this case, if we have only the event "selecting a student who has brown eyes" (at random)
The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:
P = 91/200 = 0.455...
Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.
In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:
P = 32/90 = 0.355...
So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.

Jet bought a computer that was 20% off. If the original price of the computer was $785, how much did Jet save? How much did Jet pay?
785·20%=157
785-157=628
Answer:
You will pay $628 for a item with original price of $785 when discounted 20%. In this example, if you buy an item at $785 with 20% discount, you will pay 785 - 157 = 628 dollars.

f(x)=6x-90+27
What is the domain?The domain is the set of points at which the function is defined.
What is the range?
The range of a set of data is the difference between the largest and smallest values. The difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.
To f(x) = 6x - 63, it will cross all x and y values.

Answer:
x = 3
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the secant's external part and the entire secant, that is
8(8 + 2x + 4) = 12²
8(12 + 2x) = 144 ( divide both sides by 8 )
12 + 2x = 18 ( subtract 12 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
