Answer:
Step-by-step explanation:
6(k + 2) + 1 = 13 (distribute 6 around the k+2)
6k + 12 + 1 = 13 (add 12 and 1)
6k + 13 = 13 (subtract 13 from both sides)
6k = 0 (divide by 6)
k = 0
Answer:
6( k + 2 ) + 1 = 13
6k + 12 + 1 = 13
6k + 13 = 13
6k = 0
k = 0/6
so it will 0

Answer:
Right isosceles triangle
Step-by-step explanation:
I took the quiz and got it wrong, but it told me the correct answer
A right isosceles triangle has exactly 2 equal sides and one right angle.
Given that, a triangle has exactly 2 equal sides and one right angle.
Isosceles triangle: An isosceles triangle is a triangle that has two sides of equal length.
Right isosceles triangle: An isosceles right triangle is defined as a right-angled triangle with an equal base and height which are also known as the legs of the triangle.
Obtuse isosceles: An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90° and 180°), and the other two acute angles are equal in measurement.
Right triangle: A right triangle is a triangle in which one angle is 90°.
Hence, right isosceles triangle has exactly 2 equal sides and one right angle.

The perimeter of this shape is 40cm
Calculate the value of x
Answer:
x = 8
Step-by-step explanation:
The perimeter (P) is calculated as
P = 2(l + b) ← l is length and b is breadth
Here l = 12 and b = x , P = 40, then
2(12 + x) = 40 ( divide both sides by 2 )
12 + x = 20 ( subtract 12 from both sides )
x = 8
1. The height of a missile t seconds after it has been fired is given by h=4.9t^2+44.1t. How many seconds will it take for the rocket to reach its greatest height?
Answer:
The rocket will take 4.5 seconds to reach its maximum height.
Step-by-step explanation:
The height of a missile t seconds after it has been fired is given by h=-4.9*t²+44.1*t
This function is a quadratic function of the form f (x) = a*x² + b*x + c. In this case a=-4.9, b=44.1 and c=0
To calculate how many seconds it will take for the rocket to reach its maximum height, I must calculate the maximum of the function. The maximum of a quadratic function is the vertex of the parabola. The x coordinate of the vertex will be simply: [tex]x=\frac{-b}{2*a}[/tex]. The y coordinate of the vertex corresponds to the function evaluated at that point.
In this case the x coordinate of the vertex corresponds to the t coordinate. In other words, by calculating the x coordinate of the vertex, you are calculating the maximum time t it will take for the rocket to reach its maximum height. So:
[tex]t=\frac{44.1}{2*(-4.9)}[/tex]
t=4.5
The rocket will take 4.5 seconds to reach its maximum height.

Linda and Philip share £54 in the ratio 4:5. Find how much money each of them will recieve
Answer:
Linda has £24 and Philip has £30.
Step-by-step explanation:
Denote a variable to the amount of money Linda and Philip have:
Money Linda has = L
Money Philip has = P
L + P = 54
There is a ratio of 4:5 so for every £4 Linda has, Philip will have £5. When adding both values, 4+5, you get 9.
Divide the total amount of money by the sum of the ratio numbers so 54/9 which gives 6.
Multiply the number you get from the division by their respective ratios.
Linda = 6 * 4 = 24
Philip = 6 * 5 = 30
Add both numbers if you want to make sure the answer is correct.
Write the equation of the line that goes through (9,-4) and is perpendicular to the line
y = -3x – 8
Answer: y = (1/3)*x - 7
Step-by-step explanation:
When we have a line:
y = a*x + b
A perpendicular line to this one needs to have a slope s equal to:
s = -(1/a)
Then any line written as:
y = -(1/a)*x + c
is perpendicular to the lines of the form "y = a*x + b"
Then if we have the line:
y = -3*x - 8
The family of perpendicular lines to this one is:
y = -(1/-3)*x + c
y = (1/3)*x + c
where c can be any real number.
Now we also want that this line passes through the point (9, -4)
Then we need to replace x by 9, and y by -4
-4 = (1/3)*9 + c
Now we can solve this for c.
-4 = 9/3 + c
-4 = 3 + c
-4 - 3 = c
-7 = c
Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:
y = (1/3)*x - 7

no solution

Given:
The system of equation is

[tex]y=-\dfrac{1}{3}x-4[/tex]
To find:
The solution of given system of equations.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
Write the given equation in slope intercept form.
The first equation is
[tex]y-8=-\dfrac{1}{3}x-4[/tex]
[tex]y=-\dfrac{1}{3}x-4+8[/tex]
[tex]y=-\dfrac{1}{3}x+4[/tex] ...(i)
Here, slope is [tex]-\dfrac{1}{3}[/tex] and y-intercept is 4.
The second equation is
[tex]y=-\dfrac{1}{3}x-4[/tex] ...(i)
Here, slope is [tex]-\dfrac{1}{3}[/tex] and y-intercept is -4.
Since the slopes of both lines are same but the y-intercepts are different, therefore the given equations represent parallel lines.
Parallel lines never intersect each other. So, the given system of equation has no solution.
Hence, the correct option is B.
