Answer:
12/ x^2+7x
Step-by-step explanation: Took the test and got it right
The product of the expression 3/(x+7) and 4/x is equivalent to the expression 12/(x^2+7x) option 12/(x^2+7x) is correct.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
The polynomial can be represented as:
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have polynomial:
[tex]\rm = \frac{3}{x+7}\times \frac{4}{x}[/tex]
[tex]=\rm \frac{3\times4}{x(x+7)}[/tex]
[tex]\rm = \frac{12}{x^2+7x}[/tex]
Thus, the product of the expression 3/(x+7) and 4/x is equivalent to the expression 12/(x^2+7x) option 12/(x^2+7x) is correct.

What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
5. The graph of this function is constant for all values of x, y = 3.
6. The graph of this function has points (0, 3) and (3, 2).
m = (2 - 0)/(3 - 0).
m = 2/3.
2 = (2/3)×3 + b.
2 = 2 + b.
b = 0.
y = (2/3)x.
7. The graph of this function has points (0, 1) and (3, 2).
m = (2 - 0)/(3 - 1).
m = 2/2.
m = 1.
2 = 1(3) + b.
2 = 3 + b.
b = -1.
y = x - 1.
8. The graph of this function has points (- 3, 0) and (0, 3).
m = (3 - 0)/(0 + 3).
m = 1.
3 = 1(0) + b.
b = 3.
y = x + 3.
9. The graph of this function is a vertical line parallel to the y-axis,
x = 3.
10. The graph of this function has points (0, 0) and (- 1, 3).
m = (3 - 0)/(- 1 - 0).
m = 3/ - 1.
m = - 3.
0 = - 3(0) + b.
b = 0.
y = - 3x.

- 3/8 + 3/4 + -1/4 = ?
Evaluate the expression as a fraction.
Rewrite all the fractions to have the same denominator:
3/4 = 6/8
-1/4 = -2/8
Now you have -3/8 + 6/8 + -2/8
-3/8 + 6/8 = 3/8
3/8 + -2/8 = 3/8 - 2/8 = 1/8
The answer is 1/8
Erik works 55 hours a week making $12.50 hour? His employer pays time and a half for hours over 40. Find his gross pay.
Answer:
781.25
Step-by-step explanation:
Regular pay = 40*12.50 = 500.00
Overtime = 15*12.5*1.5 = 281.25
Gross pay = 500.00 + 281.25 = 781.25

Solve for x by cross multiplying:

Subtract 25 from both sides:

For the two similar figures, the expression can be written as:
[tex]\dfrac{GH}{AB} = \dfrac{JD}{CD}[/tex]
What is the similarity?In geometry, similarity refers to the property of two figures that have the same shape but possibly different sizes. Two figures are considered similar if their corresponding angles are congruent and their corresponding sides are proportional.
For example, two triangles are similar if they have the same shape but can be different in size. This means that the corresponding angles of the two triangles are equal and the corresponding sides are in proportion.
The symbol used to denote similarity is "~". For example, if triangle ABC is similar to triangle DEF, we write it as:
ABCDE~GHJDF are similar. So the ratios of the sides of the figure can be written as,

What is the equation of a line parallel to the y axis?
Answer:
If any point on AB, then x = a. Hence, the equation of a straight line parallel to y-axis at a distance a from it is x = a.
Step-by-step explanation:
Thus, if P(x, y) is any point on AB, then x = a. Hence, the equation of a straight line parallel to y-axis at a distance a from it is x = a. The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it.

If r= 1 and 0 = 5 pie/4, what is the approximate arc length?
A. 1.25 units
B. 4.189 units
C. 3.927 units
D. 3.665 units
9514 1404 393
Answer:
C. 3.927 units
Step-by-step explanation:
The arc length (s) is given by ...
s = r·θ
s = 1·5π/4 ≈ 3.92699
s ≈ 3.927 . . . units
The length of the given arc is 3.927 units, so the correct option is C.
How to get the arc length?
For an arc in a circle of radius R, defined by an angle θ, the length is:
L = θ*R
In this case, we have:
R = 1 unit.
θ= (5/4)pi
Where pi = 3.14159
Replacing that in the length equation we get:
L = (5/4)*3.14159*(1 unit) = 3.927 units.
So the correct option is C.

The three inside angles (A, B and C) of a right angled triangle are in the ratio 7:18:11
The smallest angle is 35°
Work out out angles a,b and ,
Answer:
Angle A =35 degrees, Angle B = 90 degrees, and Angle C = 55 degrees
Step-by-step explanation:
So all the angles added up would be 180. Let's use the variable x. The angles would be 7x, 18x, and 11x.
The smallest angle is 35, and 7x is the smallest out of all them since x has to be positive.
7x = 35
x = 5
Then substitute x into each angle.
They would be 35 degrees, 90 degrees, and 55 degrees
