what form is the equation 12y=2x=24
Answer:
Step-by-step explanation:
Simplifying
12y + 2x = 24
Reorder the terms:
2x + 12y = 24
Solving
2x + 12y = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12y' to each side of the equation.
2x + 12y + -12y = 24 + -12y
Combine like terms: 12y + -12y = 0
2x + 0 = 24 + -12y
2x = 24 + -12y
Divide each side by '2'.
x = 12 + -6y
Simplifying
x = 12 + -6y
. Chris read 25 books in 135 days. At this rate, in how many days will he read another 5 books? Another 10 books?
Answer:
5 books - 27 days
10 - 54 days
15 books - 81 days
Step-by-step explanation:
First, you need to find how many days it takes to read one book, to do this, simply divide 135 by 25 (135/5=5.4). Then, you multiply that number by the amount of books it wants to know how long it would take him to read (5 and 15 since it asks "another 10". It could also be 54 if it was asking how many for 10 books not including the 5 he would have read). 5*5.4=27, 10*5.4=54, and 15*5.4=81.

The Hiking Club is on a trip to hike up a mountain. The members increased their elevation 290 feet during their hike
this morning. Now they are at an elevation of 450 feet.
a. Explain how to find their elevation before the hike.
b. Han says the equation e + 290 = 450 describes the situation.
What does the variable e represent?
C. Han says that he can rewrite his equation as
e = 450 + -290 to solve for e. Compare Han's strategy to your
strategy for finding the beginning elevation.
Answer:
Step-by-step explanation:
A. Subtract 290 from 450, 450-290= 160
B. The variable e represents the elevation before they started the hike
C. 450+-290= 450-290
The requried elevation before the hike is given as 160 feet and the required equation model of the situation is e + 290 = 450 where e represents the elevation before the hike.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
a. To find the members' elevation before the hike, we can subtract the increase in elevation from their current elevation. So, their elevation before the hike would be 450 - 290 = 160 feet.
b. In the equation e + 290 = 450, the variable "e" represents the members' elevation before the hike.
c. Han's strategy for finding the beginning elevation involves adding -290 to both sides of the equation e + 290 = 450 to get e = 450 + -290. This is equivalent to subtracting 290 from both sides of the equation e + 290 = 450. Both strategies result in the same equation, e = 160, which tells us that the members' elevation before the hike was 160 feet.

Answer:
Step-by-step explanation:
5=h/1.25
h=6.25
On solving for the value of {h}, we get -

What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is the expression as -
5 = h/1.25
We can solve for the value of {h} as -
5 = h/1.25
{h} = 5 x 1.25
{h} = 5 x 125/100
{h} = 125/20
{h} = 6.25
Therefore, on solving for the value of {h}, we get -

find an equation of line containing (3, -4) and having slope -2. if this line contains the points (a, 8) and (5, b) find a and b
Answer:
a = -3
b = -8
Step-by-step explanation:
Equation for a line is:
y-coordinate = (slope * x-coordinate) + y-intercept
For (3, -4): -4 = (-2 * 3) + y-intercept
y-intercept = 2
Equation for all points on this line is:
y = -2*x + 2
For (a, 8): 8 = (-2 * a) + 2
For (5, b): b = (-2 * 5) + 2
What is the relationship between the angle of depression of a person looking down from the top of a hill at their friend standing on the ground and the angle of elevation of the person on the ground looking up at their friend who is standing on top of the hill?
a. the angle of elevation will be greater than the angle of depression because the person has to look up from the ground to see their friend at the top of the hill
b. The angle of depression and angle of elevation will add to 180°
c. The angle of depression and angle of elevation will be the same
d.The angle of depression would be greater than the angle of elevation because the hill is higher than the ground
Answer:
C) angle of depression and angle of elevation will be the same.
this is because the horizontal for angle of elevation and angle of depression are parallel
therefore, the two angles are same (alternate angles)
hope it helps.
pls mark brainliest !!!
The correct answer is (c) The angle of depression and angle of elevation will be the same.
What is an angle of depression?When a person is standing on top of a hill and looking down at their friend standing on the ground, the angle formed between the line of sight and a horizontal line is called the angle of depression.
Similarly, when a person on the ground is looking up at their friend who is standing on top of the hill, the angle formed between the line of sight and a horizontal line is called the angle of elevation.
Since the two angles are formed by the same two points and are measured with respect to the same horizontal line, they will be congruent or the same. Therefore, option (c) is correct.

Answer:
(2, 0)
Step-by-step explanation:
Given the simultaneous equation
2x-y = 4
3x+y = 6
Add both equation
2x+3x = 4 + 6
5x = 10
x = 10/5
x = 2
Substitute x = 2 into equation 1
From1 ;
2x-y = 4
2(2) - y = 4
4 - y = 4
y = 4-4
y = 0
Hence the solution to the system of equation is (2, 0)

The base and corresponding height of a parallelogram are 75 cm and 25 cm. If the other base is 50 cm, find out its corresponding height.
Answer:
Height of the parallelogram = 37.5 cm
Step-by-step explanation:
As given,
Base of a parallelogram = 75 cm
Height of a parallelogram = 25 cm
As,
we know that
Area = Base × Height
= 75 × 25
= 1875 cm²
As the parallelogram is same
So, Area = Base × Height
⇒1875 = 50 × Height
⇒ Height = [tex]\frac{1875}{50}[/tex] = 37.5 cm
So, we get
Height of the parallelogram = 37.5 cm

g(-4) and g(4)=
Using the graph
Answer:
g(-4) = 1 g(5) = -3
Step-by-step explanation:
Step 1: Recognize this is in function notation
In funcion notation what is in the brackets are the x coordinates of the point
Step 2: Solve
We see the first one is g(-4) so we head to the left side of the x-axis and look for a point on the line that has the x value of -4. We see that at x = -4 y is equal to 1 so g(-4) is equal to 1
Next we take a look at g(5) so we look at the right side of the x-axis and see that the line crosses x=5 at y=-3 so the value of g(5) is -3

Different dealers may sell the same car for different prices. The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively. Suppose we select one of these cars at random. Let X represent the sale price (in thousands of dollars) for the selected car.1. Find P(26< X<30) You may round your answer to two decimal places
Answer:
0.48
Step-by-step explanation:
Mean, m = 26000 ; Standard deviation, s = 2000
P(x < x)
Zscore = (x - m) / s
P(26< X<30) ;
P[(26 - 26 / 2) < (30 - 26) / 2)]
P[(0 < Z < 2)]
P(Z < 2) - P(Z <0)
Using a z table of z calculator, we can obtain the probabilties of the Z value :
0.97725 - 0.5
= 0.47725
= 0.48 ( 2 decimal places)
