In the diagram below of triangle HIJ, K is the midpoint of HJ and L is the
midpoint of IJ. If KL = -8x +96, and HI= -8x + 120, what is the measure
of KL?
H
L
Answer: 24
Step-by-step explanation: HI = 2 times KL
-8x + 120 = 2(-8x + 96)
-8x + 120 = -16x + 192
8x = 72
x = 9
KL = -8x + 96
KL = -8(9) + 96
KL = 24

An angle measures 111.4° more than the measure of its supplementary angle. What is the measure of each angle?
The measure of the supplementary angles are 34.3 and 145.7 degrees.
What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees.
In other words, two angles are Supplementary when they add up to 180 degrees.
Therefore, the angles measures 111.4° more than the measure of it's supplementary angle.
Hence,
let
x = measure of the other angle
x + x + 111.4 = 180
2x + 111.4 = 180
subtract 111.4 from both sides
2x + 111.4 - 111.4 = 180 - 111.4
2x = 68.6
divide both sides by 2
x = 68.6 / 2
x = 34.3
Other angle = 34.3 + 111.4 = 145.7°
Therefore, the measure of the supplementary angles are 34.3 and 145.7 degrees.

$850 at 7% compounded annually for 3 years how do you calculate earned interest?
Answer:
$191.29
Step-by-step explanation:
Use the formula
[tex]A = P(1 + \dfrac{r}{100})^n[/tex]
where P is amount deposited, A the accrued amount, n number of years and r the interest rate in % compounded annually
The division by 100 is necessary to convert r% to a decimal for calculations
We have P = 850, r = 7% and n = 3
Plugging these in we get
[tex]A = 850\cdot (1 + (\dfrac{7}{100})^3\\\\A= 850\cdot(1 + 0.07)^3\\A = 850\cdot1.07^3\\\A = \$1,041.29[/tex]
Interest = A - P = 1041.29 - 850 = $191.29

The correct statements regarding the linear function in the graph are:
The three points form a straight line.The graph does not pass through the origin.The graph does not a show a proportional relationship.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the points, we have that:
When x changes by 4, y changes by 6.When x changes by 6, y changes by 9.When x changes by 2, y changes by 3.Hence these points form a straight line with a slope of 1.5, that is:
y = 1.5x + b.
When x = 1, y = 3, hence we use it to find b as follows:
3 = 1.5 + b
b = 1.5.
Hence the relation is:
y = 1.5x + 1.5.
Since the y-intercept is different of 0, we have that:

Step-by-step explanation:
For every 21 litres of petrol a car can run for 80 km.
How much petrol do you need (to 1 DP) to ensure the car has enough petrol of a trip that is 224 km?
For every 21 liters of petrol a car can run for 80 km- 58.2 liters of petrol would be required to ensure the car has enough petrol of a trip that is 224 km unitary method
It is provided that to run 80km car requires 21 liters of petrol
To know how much petrol is required for a trip of 224 km, we first would require to know how much petrol is required to run 1 km
This is called unitary method
Petrol required by car to run 1 km would be petrol required by car to cover 80kms of distance divided by 80 km of distance = 21 liters of petrol/ 80 km distance
= 21/80
=0.26 liters
So, petrol required by car for a trip of 224 km= 0.26 liters ×224km
= 0.26× 224

Answer:
(-7, 5)
Step-by-step explanation:
You want to know the image of the point (-4, -6) after reflection in the x-axis and translation 3 left and 1 down.
Composition of transformationsThe composition ...
[tex]T_{-3,-1}\circ r_{\text{x-axis}}[/tex]
is interpreted to mean reflection in the x-axis occurs first, then translation by (-3, -1).
That is, a composition of transformations is evaluated right to left.
ReflectionReflection in the x-axis moves a point from below the x-axis to the same distance above the x-axis. That is, the sign of the y-coordinate changes:
(-4, -6) ⇒ (-4, 6) . . . reflection in the x-axis
TranslationThe translation vector is added to the coordinates of the point:
(-4, 6) +(-3, -1) = (-4-3, 6-1) = (-7, 5)
The image of the point is located at (-7, 5).
Which statement is true about the end behavior of the
graphed function?
0 As the x-values go to positive infinity, the function's
values 90 to negative infinity.
As the x-values go to zero, the function's values go
to positive infinity.
As the x-values go to negative infinity, the function's
values are equal to zero.
O As the x-values go to positive infinity, the function's
values go to positive infinity.
Answer: B) as the x-values go to negative infinity, the functions values go to positive infinity.
Step-by-step explanation:
The graph of g is a translation 2 units left and 3 units up, followed by a reflection
in the y-axis of the graph of f(x) = x² - 2x.
Graph of g is a translation where g(x) = (x+2)^2 - 2x – 1
f(x) = x^2 - 2x
g(x) = f(x+2) + 3
Translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis. A translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system. In a Euclidean space, any translation is an isometry.
Hence , g(x) = (x+2)^2 -2(x+2) + 3 = (x+2)^2 - 2x - 1. When we graph the equations, we can confirm that our answer is correct.

three-unit class and a C in a three-unit class, what is the student's grade point average?
Answer:

Step-by-step explanation:
A in a 4-unit class will be 4 x 4 = 16 points
B in a 3-unit class will be 3 x 3 = 9
C in a 3-unit class will be 2 x 3 = 6

On a number line, B is between a and c. AB = 1/3ac
We may infer from the number line that A and B are separated by 8 units (AB).
Let AB stand for the separation between points A and B, and let AC stand for the separation between points A and C. Let B stand for the separation between points B and C. Hence:
Point B being halfway between A and C, we can infer:
AB + BC Equals AC (Postulated segment addition)
As a result, since the distance between points A and B is equal to 1/3 of AC:
AC/3 = AB = 1/3(AC)
But as shown in the accompanying image:
AC equals 16 – (–8) to 24 units.
Therefore:
AB = 1/24 = 8 unit
A and B are separated by 8 units.

Twenty less than four times an mover is twenty one what is the number
Answer:
10.25
Step-by-step explanation:
Define the variable
Let x be the unknown number.
Therefore:
[tex]\begin{aligned}& \textsf{Four times a number}: \quad & 4x\\& \textsf{Twenty less than four times a number}: \quad & 4x-20\\& \textsf{Twenty less than four times a number is twenty one}: \quad & 4x-20=21\end{aligned}[/tex]
To find the number, solve the found equation for x:
[tex]\begin{aligned}\implies 4x-20&=21\\4x-20+20&=21+20\\4x&=41\\\dfrac{4x}{4}&=\dfrac{41}{4}\\x&=10.25\end{aligned}[/tex]
Therefore, the unknown number is 10.25.
As an improper fraction, this is ⁴¹/₄.
As a mixed number, this is 10 ¹/₄.
Answer:
x = 10.25
Step-by-step explanation:
Given that,
→ Twenty less than four times a number is twenty one.
The equation we form,
→ 4x - 20 = 21
Now the value of x will be,
→ 4x - 20 = 21
→ 4x = 21 + 20
→ x = 41/4
→ [ x = 10.25 ]
Hence, the number is 10.25.
