Answer:
The sum is 2. ...........
Answer:
11 + x = -9
x = -20
Step-by-step explanation:
"The sum of eleven and a number" can be translated to: 11 + x, where 'x' is the unknown number.
[tex]11 + x = -9\\\rule{150}{0.5}\\11 - 11 + x = -9 - 11\\\\\boxed{x = -20}[/tex]
Hope this helps.

Find the value of K so that line passing through the points (k,-1) and (-2,8) is parallel to the equation 3x+y=-7
Answer:
k =1
Step-by-step explanation:
3x + y = -7
y = -3x - 7
m = -3
Parallel lines have same slope
[tex]Slope = -3\\\\\dfrac{8-[-1]}{-2-k}=-3\\\\\\\dfrac{8+1}{-2-k}=-3\\\\\dfrac{9}{-2-k} = -3[/tex]
Cross multiply,
9 = -3(-2-k)
9 = 6 + 3k
9-6 = 3k
3 = 3k
3/3 = k
k = 1
If lines l and m are parallel, then find the value of y.

What is 1/3 by the power of 4 in the simplest form. No links.
(1/3)^4 = 1^4/ 3^4 = 1/81
Answer: 1/81
The expression 1/3 by the power of 4 when evaluated has a value of 1/81
How to evaluate the expressionFrom the question, we have the following parameters that can be used in our computation:
1/3 by the power of 4
Express as an equation
So, we have
1/3 by the power of 4 = 1/3⁴
When expanded, we have
1/3 by the power of 4 = 1/3 * 1/3 * 1/3 * 1/3
Evaluate the products
This gives
1/3 by the power of 4 = 1/81
Hence, the solution is 1/81

Find the measures of the interior angles.
what is angle B and C?
Answer:
x = 42
Step-by-step explanation:
The square at ∠C means it is a right angle (90°). The sum of the angles of a triangle is 180°. Use the information to solve for ∠B.
[tex]x+48+90=180\\x+138=180\\x=42[/tex]
Answer:
B = 41 degreed
Step-by-step explanation:
Square of C = 90degrees
A = 49degrees
90 + 49 = 139degrees
180degrees - 139degrees = 41 degrees

What number cannot be divided into 9 groups without a remainder?
Answer:
The answer is B) 432
Step-by-step explanation:
The 4 in 432 becomes a 3, because we can't subtract 6 from 3. The 3 becomes 13 and if we subtract 13 with 6... We get 7.
I got 0 with option B... With A I got 2 which is a remainder. With C I got 6.5 (repeating). And with D I got 7.77777777778.
Hence, B) 432 is the correct option.
Check screenshot of my work below.
(I forgot to include 48 on top of the division I just did. Don't mind that too much..)
A) 326

[tex] = 59[/tex]
D) 630

A model rocket is launched from the top of a building. The height (in meters) of the rocket above the grown is given by h(t)=-6t^2+30t+10 , where t is the time (in seconds) since the rocket was launched. What is the rocket’s maximum height?
Answer:
47.5 Meters
Step-by-step explanation:
Find where the derivative changes from positive to negative (local maximum)
h(t)=[tex]-6t^2+30t+10[/tex]
h'(t)=[tex]-12t+30[/tex]
Find where the derivative equals zero
Theres no spot where the derivative wont exist because its a polynomial.
-12t=-30
t=[tex]\frac{5}{2}[/tex]
Ill stop here because this is a parabola opening down and this is the only spot where there will be a horizontal tangent line so this is the x-coordinate of the vertex. AKA you don't need to test positive and negative on both sides.
Now plug into original equation
h(2.5)=[tex]-6(2.5)^2+30(2.5)+10[/tex]
=-37.5+75+10
=47.5
How many solutions can be found for the system of linear equations represented
on the graph?
A) no solution
3) one solution
D) infinitely many solutions
C) two solutions
Answer:
Infinitely Many Solutions
Step-by-step explanation:
They are the same line so they cross each other infinitely many times.
If you picked a point on the first equation it would be the same point on the second equation.
Answer:
D) Infinitely many solutions
Step-by-step explanation:
Given the follwowing systems of linear equations, y = x + 2, and -3x + 3y = 6:
Transforming -3x + 3y = 6 into its slope-intercept form, y = mx + b:
-3x + 3y = 6
Add 3x to both sides:
-3x + 3x + 3y = 3x + 6
3y = 3x + 6
Divide both sides by 3:
[tex]\frac{3y}{3} = \frac{3x + 6}{3}[/tex]
y = x + 2 ⇒ This is the slope-intercept form of -3x + 3y = 6. Since they are equivalent equations, then it means that their graphed lines coincide. Since any point on either lines coincide (or also exists) on the other line, then it means that the solutions to one of the equations will satisfy the other. Therefore, the given systems of linear equations have an infinitely many solutions.
the range of two numbers is 10 and their median 14.what are the two numbers
Answer: 9,19
Range: The difference between the largest and smallest data in a data set.
nineteen (19) - nine (9) = 10 (which is equivelent to the given range 10)
Median: The value in a set that is most close to the middle of a range.
nine (9) and nineteen (19) the median would be 14

Step-by-step explanation:
Interest Rate = (Simple Interest × 100)/(Principal × Time).
I= 7000(.0245)(7)
I=1200.5
Answer:
1,200.5
Step-by-step explanation:
Simple interest is
I = Prt,
where I is the interest earn after t years, P is the initial money , r is the rate
I = 7000*.0245*7 = 1,200.5
1,200.5 is the interest after 7 years

Question 6 answer is: C and Question 7 answer is: A
Step-by-step explanation:
It's simple to divide for Question 6 because you just have to show the difference between the exponents. 5 - 2 = 3 and 7 - 3 = 4 so choice C is the best answer.
For question seven, the radical index is 3 so rewrite the equation as 300^(1/3). The answer will be around 6.69 which is between 6 and 7 so the answer is A.

What is Zeros of polynomial?
Zeroes of a polynomial are the points where the polynomial becomes zero.
Given that;
Zeroes of the polynomial are 2, 5 - i
Now, If one zero of polynomial is complex then another zero of the polynomial is its conjugate.
So, One root of polynomial = 5 - i
Then, The third zero of the polynomial = 5 + i
Thus, The polynomial are find as;
(x - 2) (x - (5-i)) (x - (5 + i)) = 0
So, The remaining zero of polynomial is (5 + i).
And, the linear factorization of the polynomial are;
(x - 2) (x - (5-i)) (x - (5 + i)).

Answer:
8Step-by-step explanation:
Let the numbers are:
6, x, y, 2Since the sequence is arithmetic, the difference of two consecutive terms is same:
d = x - 6 = y - x = 2 - yTherefore:
x = 6 + dy = 6 + 2d2 = 6 + 3dThe sum of the first two equations:
x + y = 6 + d + 6 + 2d = 6 + (6 + 3d)Substitute (6 + 3d) with 2 (the third equation) to get:
