Answer:
No solution
Step-by-step explanation:
Equation C :
y = 6x + 9
Equation D :
y = 6x + 2
By comparing both the equations with slope-intercept form of the equation,
y = mx + b
Where, m = Slope of the line
And b = y-intercept
Slopes of both the lines C and D are common as 6,
Therefore, both the lines will be parallel.
And the set of parallel lines has no solution.
Therefore, given set of equations have no solution.

Using trigonometric identities, it is found that the value of the tangent of the angle is given by:
B. [tex]-\frac{\sqrt{15}}{7}[/tex]
What is the tangent of an angle?The tangent of an angle is given by it's sine divided by it's cosine, that is:
[tex]\tan{\theta} = \frac{\sin{\theta}}{\cos{\theta}}[/tex]
In this problem, we have that:
[tex]\cos{\theta} = -\frac{7}{8}[/tex]
The following identity is applied:
[tex]\sin^2{\theta} + \cos^2{\theta} = 1[/tex]
Then:
[tex]\sin^2{\theta} + \left(-\frac{7}{8}\right)^2 = 1[/tex]
[tex]\sin^2{\theta} + \frac{49}{64} = 1[/tex]
[tex]\sin^2{\theta} = \frac{15}{64}[/tex]
[tex]\sin{\theta} = \pm \frac{\sqrt{15}}{8}[/tex]
Since it is on the second quadrant, it is positive, hence:
[tex]\sin{\theta} = \frac{\sqrt{15}}{8}[/tex]
Applying the tangent equation:
[tex]\tan{\theta} = \frac{\sin{\theta}}{\cos{\theta}}[/tex]
[tex]\tan{\theta} = \frac{\frac{\sqrt{15}}{8}}{-\frac{7}{8}}[/tex]
[tex]\tan{\theta} = -\frac{\sqrt{15}}{7}[/tex]

Find the surface area of this prism.
Round to the nearest tenth.
Answer:
The answer is 493.3
Step-by-step explanation:
6.72 x 12.7 x 5.78 = 493.28872
And 493.28872 rounded to the nearest tenth is 493.3 because the original number in the tenth place is 2 and then the digit before that is 8 which in this case is your rounding digit. Round up If the number is greater than 5 and round down if its less than 5. In this case its greater than 5 to that leaves you with 28 so now you have 493.28, 28 rounded to the nearest tenth is 30 and just take the 0 away, as if it didn't exist.
The surface area of the prism is 395 square centimeter.
What is volume?Volume is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write volume as -
V = ∫∫∫ F(x, y, z) dx dy dz
Given is to fins the surface area of the prism given below.
The given prism is a cuboid. We can write the surface area of the cuboid as -
V = 2(LB + BH + LH)
V = 2(12.7 x 5.78 + 5.78 x 6.72 + 12.7 x 6.72)
V = 2(73.4 + 38.8 + 85.344)
V = 395 square centimeter
Therefore, the surface area of the prism is 395 square centimeter.

- Sketch the solution to each system of inequalities.
Find a polynomial f(x) of degree 3 with real coefficients and the following zeros. -2,- 2+i.
Answer:
f(x) = x^3 + 2x^2 + x + 2
Step-by-step explanation:
If -2 + i is a zero, then -2 - i must also be a zero.
These zeros are -2, -2 + i and -2 - i, and the corresponding factors of the polynomail f(x) are (x + 2), (x + 2 - i) and (x + 2 + i).
(x + 2 - i) and (x + 2 + i) multiplied together becomes x^2 + 1.
Multiplying this result by the 3rd and last factor, (x + 2), we get
(x^2 + 1)(x + 2) = x^3 + 2x^2 + x + 2
Check, using synthetic division. What are the factors of x^3 + 2x^2 + x + 2?
-2 / 1 2 1 2
-2 -2 -2
-----------------------
1 0 -1 0 Since the remainder is zero, we know that
(x + 2) is a factor and -2 is a root.

rewrite the equation 12x=13-x^2
Answer:
x^2+12x-13 = 0
Step-by-step explanation:
12x=13-x^2
=>12x+x^2=13-x^2+x^2
=>x^2+12x-13 = 13-13
=> x^2+12x-13 = 0
Answer:
x² + 12x - 13 = 0
Step-by-step explanation:
12x = 13 - x²
the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;
0 = 13 - x² - 12x
0 = -x² - 12x + 13
In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:
x² + 12x - 13 = 0

"Determine which three lengths cannot be the measure of the sides of a triangle. 2 m, 5 m, 6 m 8 m, 10 m, 17 m 5 m, 20 m, 22 m 4 m,15 m, 20 m"
Answer:
None.
All the four given measurements can form a triangle.
Step-by-step explanation:
Given;
first measurement, = 2m , 5m, 6m
second measurement, = 8m, 10m, 17m
third measurement, = 5m, 20m, 22m
fourth measurement, = 4m, 15m, 20m
For any of the three lengths to form a triangle, the sum of any two sides must be greater than the third side.
First measurement: 2m + 5m = 7m and 7m > 6m (can form a triangle)
Second measurement: 8m + 10m = 18m and 18m > 17m (can form a triangle)
Third measurement: 5m + 20m = 25m and 25m > 22m (can form a triangle)
Fourth measurement: 4m + 15m = 19m and 19m < 20m BUT
20 m + 15m = 35 m and 35 m > 4m (can form a triangle)
Therefore, all the four given measurements can form a triangle.
If a triangle has sides with lengths of 10 inches 12 inches and 14 inches is a right triangle?
Answer:
not a right triangle
Step-by-step explanation:
right triangles are those that prove out to be true when you square the two smaller sides and the sum is equal to the square of the longest side
true or false?
10² + 12² = 14²
100 + 144 = 196
False, ∴ not a right triangle
