2x + 24 = 2 • (x + 12)
2x + 24 = 2x + 24
This equation is a tautology or an Identity meaning it's always true.
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
4x + 37 = 2x + 13
-2x. -2x
2x + 37 = 13
-37. -37
2x = -24
x = -12
Find the slope of the line that passes through the points (1,-4) and (3,-1).
Answer:
The answer is
[tex] \frac{3}{2} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(1,-4) and (3,-1)
The slope is
[tex]m = \frac{ - 1 - - 4}{3 - 1} = \frac{ - 1 + 4}{2} = \frac{3}{2} \\ [/tex]
We have the final answer as
[tex] \frac{3}{2} \\ [/tex]

Which of the following statements about the function cannot be used to conclude that is defined at x = 1?
a) lim x—>1 f(x) exists
b) f is continuous at x = 1
c) f is differentiable at x = 1
d) the line tangent line to the graph of f at x=1 exists
a) [tex]\lim_{x \to 1} f(x)[/tex] exists
As the limit of a function at any certain point can exist, but the function itself may be not defined at that point.
For example, if [tex]f(x) =\frac{ (x^3 - 1) }{(x - 1)}[/tex], then [tex]\lim_{x \to 1}\frac{(x^3 - 1)}{ (x - 1)} = 3[/tex],
So, here f(1) is undefined as there is a hole in the graph of the function f(x) at the point (1,3).
Therefore the correct statement about the function cannot be used to conclude that is defined at x = 1 is [tex]\lim_{x \to 1} f(x)[/tex] exists.

Give the equation of the line with a slope of
1
7
and a y-intercept of 1.
Answer:
y = 17x + 1
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m = slope
b = y-intercept
Answer:
y=17x+1
Step-by-step explanation:
When a question asks us to give the equation of a line, we usually organize it into this formula:
y=mx+b
This formula is called slope-intercept form. Here's what the variables mean:
y=the y-axis
m=the slope
x=the x-axis
b=the point on the line that crosses the y-axis (the y-intercept)
So to write an equation of a line with a slope of 17 and a y-intercept of 1, we would need to plug those values in as m and b.
y=17x+1
I hope this helps! Please comment if you have any questions.

What is the LCD of 1/2 and2/17
Answer:
the answer would be 34
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/2, 2/17
For the denominators (2, 17) the least common multiple (LCM) is 34.
LCM(2, 17)
Therefore, the least common denominator (LCD) is 34.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/2 = 1/2 × 17/17 = 17/34
2/17 = 2/17 × 2/2 = 4/34
Which of the following is true about the charge of an electron?
a. It is 1.602 x 10^-19 C, and the smallest unit of charge
b. It is -1.602 x 10^-19 C, and the smallest unit of charge (THIS ANSWER IS CORRECT)
c. It is -1.602 x 10^-19, and it is a multiple of the smallest unit of charge
d. It is 1.602 x 10^-19, and it is a multiple of the smallest unit of charge
Answer:
It is -1.602 x 10^-19 C, and the smallest unit of charge
Step-by-step explanation:
The charge on an electron is [tex]1.6\times 10^{-19}\ C[/tex]. The charge on electron is negative. The quantization of electric charge is :
q = ne
q is net charge
n is no of electrons
e is the electronic charge which is [tex]-1.6\times 10^{-19}\ C[/tex]. Hence, the correct option is (b).

Use the critical value with three decimal places. a. At confidence, what is the margin of error? b. Develop a confidence interval estimate of the mean amount spent for lunch. to
Answer:
The sample is calculated by adding the samples and dividing by the number of sample size.
X ± 2.58(6$)/√64
Step-by-step explanation:
Given:
Data were collected by 64 customers for lunch.
Based on past studies, the population standard deviation is known with =∂= $6
a) At 99% confidence
By using given information,
∂= $6, n= 64,
At 99% confidence, the value of z = 2.58
By using formula of margin error:
ME=za/2 ∂/√n
= 2.58 $6/√64
= 15.48/8
=1.935
b) Find the 99% confidence interval for mean amount spent on lunch?
By using given information:
∂= $6, n= 64,
At 99% confidence, the value of z = 2.58
By using the formula:
X ± z∂/√n
Where x is the sample means, z is the %99 confidence level, which is equal to 2.58
The sample is calculated by adding the samples and dividing by the number of sample size.
X ± 2.58(6$)/√64

Hunter invested $580 in an account paying an interest rate of 4.6% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 19 years?
Answer: 1388
Step-by-step explanation:
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + R/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
The amount in the account after 19 years is $1388.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + R/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $580
R = 4.6%
n = 12 ( compounded monthly)
t = 19 years
Now,
Convert R as a percent to r as a decimal
r = R/100
r = 4.6/100
r = 0.046 rates per year,
Now,
A = P [tex](1 + R/n)^{nt}[/tex]
A = 580 [tex](1 + 0.046)^{12\times19}[/tex]
A = 580 [tex](1.0046)^{228}[/tex]
A = $1,387.64
Rounding to the nearest dollar we get,
A = $1388
Thus,
The amount in the account after 19 years is $1388.

use the following functions: yf(x) = 3x - 7
g(x) = 2x - 4
1. Find (f + g)(x).
2. Find (f - g)(x).
Answer:
(f + g) (x) = 5x - 11
(f - g) (x) = x + 3
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 2x - 4
to find ; (f + g) (x) and (f - g) (x)
now,
(f + g ) (x) = f (x) + g(x)
= (3x - 7) +( 2x - 4 )
= 3x - 7 + 2x - 4
= 5x - 11
again ,
(f - g ) (x) = f(x) - g(x)
= (3x - 7) - (2x - 4)
= 3x - 7 - 2x + 4
= x + 3
