Answer:
x = 3
Step-by-step explanation:
A line with a slope of 0 is a horizontal line parallel to the x- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
the line passes through (3, - 3 ) with x- coordinate 3 , then
x = 3 ← equation of line
Answer:
f(x) = -3
Step-by-step explanation:
it will be a constant function because if the slope = 0, the y value is not changing
so the equation of the line, f(x) = ax+b, will be f(x) = 0x+b
f(x) = b, b is the y value here

The midpoint formula can determine the midpoint of a line segment given its endpoints. The midpoint is the location midway between two endpoints, as the name may have already implied. Divide the total of the x-values by 2 and the same for y-values.
Calvin’s credit card computes finance charges using the daily balance method. His card has a billing cycle of 30 days and an APR of 14. 75%. The following table details Calvin’s transactions in the month of September. Date Amount ($) Transaction 9/1 716. 54 Beginning balance 9/7 84. 94 Purchase 9/12 15. 69 Purchase 9/20 200. 00 Payment What will Calvin’s starting balance be next month? a. $617. 17 b. $624. 74 c. $625. 91 d. $623. 52.
Answer:
c. $625. 91
Step-by-step explanation:
The average daily balance totals each day's balance for the billing cycle and divides by the total number of days in the billing cycle. Then, the balance is multiplied by the monthly interest rate to assess the customer's finance charge—dividing the cardholder's APR by 12 calculates the monthly interest rate.

question 4
from what I can see through the diagram the hypotenuse is 15 and the adjacent is 9 and we're asked to find titre
so we use the relation cos titre= adjacent/hypotenuse
cos titre= 9/15
cos titre=0.6
therefore titre is cos inverse of 0.6 which is 53.13
PLEASE HELP ME!!!!!!!!!!!
Answer:
3y
Step-by-step explanation:
Sqrt of 9 = ±3
-±3[tex]\sqrt{y^{2} }[/tex]
the square and sqrt cancel leaving you with -±3y
Since y < 0, the sqrt of 9 should be -3 to cancel out the - sign in front.

Answer:
240 cm²
Step-by-step explanation:
Split the shape into a trapezoid (top half) and a rectangle (bottom half).
Area of a rectangle = width x length
⇒ area = 6.5 x 20 = 130 cm²
[tex]\textsf{Area of a trapezoid} = \frac{1}{2}(a+b)h[/tex]
(where a and b are the lengths of the base and top, and h is the height)
⇒ [tex]\textsf{area} = \frac{1}{2}(20+20)\times5.5[/tex]
⇒ area = 110 cm²
Total area = area of rectangle + area of trapezoid
⇒ area = 130 + 110 = 240 cm²
3(2x-7=5-(1-x) pls help me
Answer:
3 • (2x - 7) - (x + 4) = 0
then do 3.1 Pull out like factors :
5x - 25 = 5 • (x - 5)
5 • (x - 5) = 0
4.2 Solve : x-5 = 0
Add 5 to both sides of the equation :
x = 5
Step-by-step explanation:
Answer:
[tex] \sf \: x = 5[/tex]
Step-by-step explanation:
Given equation,
→ 3(2x - 7) = 5 - (1 - x)
Now the value of x will be,
→ 3(2x - 7) = 5 - (1 - x)
→ 6x - 21 = 5 - 1 + x
→ 6x - x = 4 + 21
→ 5x = 25
→ x = 25/5
→ [ x = 5 ]
Hence, the value of x is 5.

10. A company finds that 45% of first-time visitors to its website do not buy any of its products. If there are 75 first-time visitors on a given day, what is the probability that exactly 36 of them buy a product? Round your answer to the nearest thousandth. Answer choices: 0.044 0.080 0.450 0.550
Using the binomial distribution, it is found that the probability that exactly 36 of them buy a product is of 0.044.
For each first-time visitor, there are only two possible outcomes, either they buy a product, or they do not. The probability of a first-time visitor buying a product is independent of any other first-time visitor, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
45% of first-time visitors to its website do not buy any of its products, hence 55% buy, that is, p = 0.55.There are 75 first-time visitors on a given day, hence n = 75.The probability that exactly 36 of them buy a product is P(X = 36), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 36) = C_{75,36}.(0.55)^{36}.(0.45)^{39} = 0.044[/tex]

Add. Simplify your answer.
Step-by-step explanation:
Add the ones with like terms.
which means the ones with things in common.
4/5x^2 + 1/4x^2 i'm adding this first because we have x^2 on both sides.
(4/5 + 1/4)x^2
= (5+16/20)x^2
= (21/20)x^2
the next terms are those with x as common.
(1/4 +- 1/5)x...take the sign into consideration while dealing with the terms within the equations.
=(1/4 - 1/5)x
=(5 - 4/ 20)x
= (1/20)x
= (1 × x) / 20
= x/20.
last ones are the constant terms(numbers)
1/6 + 2/3
=12 + 3 / 18
= 15/18...we can simplify this one as well.
= 5 × 3 / 6 × 3
= 5/6.
Now write all the results as a one equation.
descending order starting from the highest degree which is 6/5x^2 --> 1/20x ---> 5/6.

what is the distance between (-6,8) and (-3,9)
A) 4
B) 6
C) square root of 10
D) square root of 15
Answer:
I would say it is close to 4, but not 4.
Step-by-step explanation:
So I rounded the distance between the 2 plots with a line, and I got either 3.8 or 3.1
square root of 10 = 3.1
square root of 15 = 3.8
The picture is my graph I used to base it, so I would generally consider how close it is to 4 saying C. Square root of 10.
(I only chose 3.1 because I went up on the graph 3 squares with my line. It did not quite reach. I went 1/10(0.1) of a whole up further, and it resulted in the square root of 10 choice.)

Step-by-step explanation:
any root of a number can be written as fraction in the exponent of that number.
so, here, the square root of 5 is 5^1/2.
and the cubic root of 5 is 5^1/3.
what happens, when we multiply the same base number with exponents ?
a^n × a^m = a^(n+m)
and so we get here
5^1/2 × 5^1/3 = 5^(1/2 + 1/3)
how do we add fractions with different denominators ?
we bring them to the same denominator, usually by using the smallest (or least) common multiple of the existing denominators, which is 6 for 2 and 3.
so,
1/2 + 1/3 = 3/6 + 2/6 = 5/6
therefore, the simplified solution is
5^5/6
the first answer option is correct.

Given system:
x + y = 6 6x - 5y = 14 Solve by elimination, multiply the first equation by 5 and add up equations:
5x + 5y + 6x - 5y = 5*6 + 1411x = 44x = 4Find y:
4 + y = 6y = 6 - 4y = 2Answer:
x = 4
y = 2
Step-by-step explanation:
Rewrite x + y = 6 to make y the subject:
⇒ y = 6 - x
Substitute y = 6 - x into 6x - 5y = 14 and solve for x:
⇒ 6x - 5(6 - x) = 14
⇒ 6x - 30 + 5x = 14
⇒ 11x - 30 = 14
⇒ 11x = 44
⇒ x = 4
Substitute x = 4 into x + y = 6 and solve for y:
⇒ 4 + y = 6
⇒ y = 2
