Answer:
Alright, so we got k + 9k = 8k - 6.
This means that 10k = 8k - 6.
As a result, we have 2k = -6, and k = - 6/2 = -3
So, k = -3 :)

Write the equation of a line that is perpendicular to y = 0.25x - 7 and that passes through the point (-6,8).
Answer:
y = -4x -16
Step-by-step explanation:
Line perpendicular have the slope = -1/m
Substitute the values,
8 = (-4)(-6) + c
8 = 24 + c
c = -16
Thus, the equation of the perpendicular line is y = -4x-16

2х + 5y= 25
Answer: 2х+5y=25= Slope = -0.800/2.000 = -0.400
x-intercept = 25/2 = 12.50000
y-intercept = 25/5 = 5
so slope form =0,400
x intercept form = 12.50000
y intercept =5
and the answer to 2x+3y=-1= Slope = 1.333/2.000 = 0.667
x-intercept = 1/2 = 0.50000
y-intercept = -1/3 = -0.33333
Step-by-step explanation: an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2x+5y-25 = 0 and calculate its properties
Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000
y-intercept = 25/5 = 5
When y = 0 the value of x is 25/2 Our line therefore "cuts" the x axis at x=12.50000
x-intercept = 25/2 = 12.50000
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 4.200. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 4.200 - 5.000 = -0.800 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -0.800/2.000 = -0.400
Geometric figure: Straight Line
Slope = -0.800/2.000 = -0.400
x-intercept = 25/2 = 12.50000
y-intercept = 25/5 = 5

The length and width of a rectangle are in a ratio of 7:11. If the perimeter of the
rectangle is 72 cm. Find the
length and
width of the rectangle.
Answer:
14cm and 22cm
Step-by-step explanation:
Given parameters:
Perimeter of rectangle = 72cm
Ratio of length to width = 7: 11
Unknown:
Length and width of the rectangle = ?
Solution:
Since the ratio of length to width is 7: 11,
if the length is 7x , width = 11x
The perimeter of a rectangle can be obtained using
Perimeter = 2(L + W)
Insert the parameters and solve;
72 = 2(7x + 11x )
72 = 2(18x)
x = [tex]\frac{72}{36}[/tex] = 2
The length = 7x = 7x2 = 14cm
width = 11x = 11 x 2 = 22cm
Select the equivalent expression.

The half-life of a certain radioactive material is 36 days. An initial amount of the material has a mass of 487 kg. Write an exponential function that models the

OD
: 0 kg
Answer:
a(t) = 487(1/2)^(t/36)a(5) = 442.302 kgStep-by-step explanation:
The exponential function for half-life problems is easily written using 1/2 as the base of the exponent.
present value = (initial value) × (1/2)^(t/(half-life))
Then the amount (a) remaining after t days is ...
a(t) = 487 × (1/2)^(t/36)
__
After 5 days, the amount remaining is ...
a(5) = 487×(1/2)^(5/36) ≈ 442.302 kg
_____
Some folks like their exponential function to be written using e as the base for the exponent. Here, that would be ...
a(t) = 487·e^(-0.019254t)
where the constant in the exponent is -ln(2)/36.

Answer:
x = 54angle ACD = 124°Step-by-step explanation:
The rule is that the exterior angle (ACD) is equal to the sum of the remote interior angles (the two marked angles on the right).
You are expected to use this relation to write and solve an equation.
exterior angle = angle D + angle B
(2x +16) = 58 + (x+12)
2x +16 = x +70
x + 16 = 70

What is the average rate of change of y with respect to x over the interval [-2, 6] for the function y = 5x + 2?
Answer:
5
Step-by-step explanation:
Average rate of change is slope, which is change in y over change in x:
[tex]\frac{[5(6)+2]-[5(-2)+2]}{6-(-2)} =\frac{32-(-8)}{8} =5[/tex]
The average rate of change of the function is 5.
What is the average rate of change of a function?The sum of the change in the function values (output values) divided by the change in the input values is the average rate of change between two input values.
The given interval is [-2,6] and the given function is f(x) = y = 5x + 2.
The value of the function for x = 6 is:
f(6) = 5(6) + 2
f(6) = 32
The value of f(x) for x = -2 is:
f (-2) = 5(-2) + 2
f(-2) = -10 + 2
f(-2) = -8
The average rate of change of the function is given by:
( f(6) - f(-2) )/ (6 - (-2))
= ( 32 - (-8))/ (6 + 2)
= ( 32 + 8)/8
= 40/8
= 5
Hence, the average rate of change of the function is 5.

1) Select the characteristics that are true of all parallelograms. Group of answer choices Opposite sides are never equal. Opposite angles are congruent (equal). A parallelogram can have more than 4 sides. Parallelograms have 4 sides. Opposites sides are parallel and equal in length.
Answer:
- Opposite angles are congruent (equal).
- Parallelograms have 4 sides
- Opposites sides are parallel and equal in length.
Step-by-step explanation:
A parallelogram is a quadrilateral and since quadrilaterals are fur sided figures, hence parallelograms are also four sided figures.
A parallelogram has its opposite side equal and parallel to each other with a slanting edge at two of its sides. Since its opposite sides are equal hence its opposite angles are also equal.
Parallelogram cannot have more than four sides because they are quadrilateral. Find the diagram of a parallelogram in the attached figure.

The cost of 6 1/2 kg of apples is Rs. 520. What is the rate of one kg of apples
Step-by-step explanation:
So, cost of 6.5 kg of apples is Rs. 520 and we need to find cost of one kg apples.
It can be done just by applying Unitary Method!So,
6.5 kg -- Rs. 520
1 kg -- Rs.(520/6.5) = Rs.80
So, cost of 1 kg apples is Rs.80.Need help to solve 6/4y - 12 = 1/2y - 4
