Mark think of a number mark doubles it and add 2.9 to get answer of 30.6 form an equation with x from the information
Answer:
2x + 2.9 = 30.6
Step-by-step explanation:
We are to represent the unknown number that Mark thinks of with x
If Mark doubles this unknown number, he multiplies it by 2 and the unknown number becomes - 2x
He then adds 2.9
The equation becomes 2x + 2.9
The answer of the above equation is 30.6
This gives : 2x + 2.9 = 30.6

OB
It has only one vertical asymptote.
It has only one horizontal asymptote.
D.
It has no vertical asymptote.
E.
It has no horizontal asymptote.
Answer:
tha anser us B
Step-by-step explanation:
it is very easy you just read the question carefully
The correct statement about the asymptotes of the function is it has only one horizontal asymptote.
What is Polynomial?Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
If the degree of the polynomial function in the numerator of a rational function is 1 and the degree of the polynomial function in the denominator is 2, then the rational function can be written as:
f(x) = (ax + b)/(cx² + dx + e)
The leading coefficient of the numerator is a, and the leading coefficient of the denominator is c. Therefore, the function has one horizontal asymptote given by y = a/c.
Thus, the correct statement about the asymptotes of the function is it has only one horizontal asymptote.

Work out the value of x
2x + 13
x-4
x+7
(Look at the photo attached)
Answer:
x = 41
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
2x + 13 + x - 4 + x + 7 = 180, that is
4x + 16 = 180 ( subtract 16 from both sides )
4x = 164 ( divide both sides by 4 )
x = 41
Answer:
x=41
Step-by-step explanation:
we know that all the angles need to add up to 180
The angle on top is almost a right angle(90) but is not exactly
playing with the numbers will help
95-13=82/2=41
lets continue with this and see if it works out
41+7=48

Allison needed to get her computer fixed. She took it to the repair store. The
technician at the store worked on the computer for 4.25 hours and charged her $177
for parts. The total was $623.25. What was the cost of labor, per hour?
Answer:
ans = $105 per hour
Step-by-step explanation:
first: you subtract the charge for parts from the total and this gives you $446.25.
second: because the technician worked for 4.25 hours = $446.25,if the technician worked for an hour what would be the cost?
4.25hr = $446.25
1 hr = x . then cross multiply.
4.25x = 446.25 then divide by 4.25 both sides to find th value of x, which is the cost of labour per hour

The same amount deposited weekly into a bank account can be represented by a Linear.
Therefore, option A is correct.
What is Linear Function?Linear functions have a straight line as their graph. The following is the form of a linear function. a + bx = y = f(x). There is one independent variable and one dependent variable in a linear function. x is the independent variable, and y is the dependent variable.
The degree of the model for data presented as ordered pairs can be determined by determining the differences between dependent values.
The model will be linear if the initial difference is the same value.If the second difference has the same value as the first, the model is quadratic.If the number of times the difference is calculated before obtaining repeated values surpasses five, the model could be exponential or another unique equation.If the same amount deposited weekly into a bank then the difference between consecutive deposits will be same.
Thus, the situation shows the linear function.

In a school of 310 students, 70 of them are in the drama club, 190 of them are in a sports team and 50 students do drama and sports. Find the probability that a student chosen at random isnt in the in tje drama club or the sports team
The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Let's denote students in D = in the drama club , S = in a sports team
P(D) = 70/310
P(S) = 190/310
P(D and S) = 50/310
P(D or S) = P(D) + P(S) - P(D and S)
P(D or S) = 70/310 + 190/310 - 50/310
P(D or S) = 210/310 = 21/31
P(neither D nor S) = 1- 21/31
P(neither D nor S) = 10/31
The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.

Dan and Lisa each improved their yards by planting daylilies and ivies. They bought their supplies from the same store. Dan spent $78 on 6 daylilies and 8 pots of ivies. Lisa spent $123 on 9 daylilies and 13 pots of ivies. What is the cost of one daylily? What is the cost of one pot of ivies?
Answer:
Cost of daylillies = $5
Cost of pot = $6
Step-by-step explanation:
Let
Cost of daylillies = x
Cost of pot = y
6x + 8y = 78 (1)
9x + 13y = 123 (2)
Multiply (1) by 9 and (2) by 6 to eliminate x
54x + 72y = 702 (3)
54x + 78y = 738 (4)
Subtract (3) from (4)
78y - 72y = 738 - 702
6y = 36
y = 36/6
y = 6
Substitute y = 6 into (1)
6x + 8y = 78 (1)
6x + 8(6) = 78
6x + 48 = 78
6x = 78 - 48
6x = 30
x = 30/6
x = 5
Cost of daylillies = $5
Cost of pot = $6
