Angle EBI and angle BCJ are congruent is proved as follow.
To prove that corresponding angles are congruent, we can use the transformation that takes angle EBI to angle BCJ.
First, we place angle EBI in the plane.Next, we use a transformation, such as a translation or rotation, to move angle EBI to the position of angle BCJ.Since the transformation preserves the angle measure and the angles have been superimposed on each other, we can see that angle EBI and angle BCJ have the same measure.Therefore, we can conclude that corresponding angles are congruent.
Alternatively, we can use the fact that if two lines are parallel, then the alternate interior angles are congruent and corresponding angles are congruent. Since AI and GJ are parallel, angle EBI and angle BCJ are congruent.

I’m kinda slow can someone help
Answer:
60
Step-by-step explanation:
You're not slow.
So given was the formula for perimeter
12x + 1/2 - 4x - 8.5 + 2x + 8
They want you to find perimeter is x = 6, so this is a matter of plug and play. so everywhere you see an x, you'll replace it with the number 6
And we will start simplifying what we can
P = 12(6) + 1/2 - 4(6) - 8.5 + 2(6) + 8
P = 72 + 0.5 - 24 - 8.5 + 12 + 8
P = 72 - 24 - 8 + 12 + 8
P = 72 - 12
P = 60

Angela wants to learn how to rock climb. The Rocky Climbing gym has a special where 5 climbs cost $52.50.
Select the equation that represents the total cost, t, of c climbs. Assume the relationship is proportional.
Answer: t = 10.50c
Step-by-step explanation: The relationship between the number of climbs, c, and the total cost, t, is proportional. This means that the ratio of t to c is constant. One way to represent this relationship is through an equation of the form:
t = kc
where k is a constant of proportionality. In this case, we know that 5 climbs cost $52.50, so we can use this information to find the value of k:
52.50 = k(5)
k = 52.50/5 = 10.50
So the equation that represents the total cost, t, of c climbs is:
t = 10.50c
Where t is the total cost, c is the number of climbs and 10.50 is the constant of proportionality.
how to go from slope intercept form to standard form
To go from slope intercept form of line to standard form Ax + By + C = 0, collect all terms on the left side of the equation and multiply by the denominator B.
We know that the standard form of equation of line is Ax + By + C = 0. And the slope intercept form of line is y = mx +b, where m is the slope of the line, and b is the y-intercept i.e., the value of y when x = 0.
Converting from slope intercept form to standard form:
⇒ y = mx + b
⇒ y - mx = (mx - mx) + b .........(subtract mx from each side)
⇒ y - mx = b
⇒ y - mx - b = b -b .........(subtract b from each side)
⇒ y - mx - b = 0
⇒ - mx + y - b = 0
Above equation is of the form Ax + By + C = 0

geometry - i need help with this problem and it’s pretty easy. i’m just curious on how i would round the square root of 95 within the problem
Step-by-step explanation:
I am not sure what you mean. you don't round the intermediate numbers and results. only the final result.
you keep the irrational terms (like square root) like variable terms as they are and apply operations on them without actually expressing them as numbers.
only at the very last moment (when the final result is calculated) would you express them as actual number. and then you round the final result.
so, this is solved via Pythagoras :
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.
in our case we have
BP² = BN² + NP² = 7² + sqrt(95)² = 49 + 95 = 144
you see ?
no need ever to bring the actual result of sqrt(95) into the picture. just keep it at sqrt(95) and do with it, what you would do with any actual number.
BP² = 144
BP = sqrt(144) = 12
so, we never had to deal with the actual irrational number.
we know how it is created, so we keep using that term to represent it.

Amanda explains to a classmate how to find the growth factor of an exponential function, given a table of values. She tells her classmate to choose a f ( x ) f(x) value from the table and divide it by the previous f ( x ) f(x) value.
Analyze Amanda's explanation.
If she is correct, choose one of the following ways to respond.

Create a function, in function notation, and explain how to tell what the growth factor is.
If she is incorrect, respond to the following statement.
Explain what Amanda did wrong and what should be done to correct her explanation
Amanda's explanation is not correct. The growth factor of an exponential function is the constant value that the function is multiplied by for each expansion in the information variable.
It is not determined by dividing one value in the table by the previous value.
To find the growth factor of an exponential function, one ought to take the proportion of any two consecutive f(x) values and distinguish the normal proportion. The growth factor is equivalent to this normal proportion.
For instance, assuming the function is [tex]f(x) = 2^x[/tex], and the table of values is:
x f(x)
0 1
1 2
2 4
3 8
The growth factor can be tracked down by taking the proportion of f(x) values for consecutive x:
f(1)/f(0) = 2/1 = 2
f(2)/f(1) = 4/2 = 2
f(3)/f(2) = 8/4 = 2
For this situation, the growth factor is 2, meaning that the function is multiplied by 2 for each increase in x.

the sum is 1) 5/3, 2) 5/6 , 3) 7/10 and the difference is 1) 1/6 , 2)2/15, 3) 1/30. When adding or subtracting fractions with unlike denominators, the first step is to convert the fractions so that they have a common denominator.
1. 1/3+2/3 = 5/3
2. 1/2 + 1/3 = 5/6
3. 2/5+1/2 = 7/10
1. 1/2-1/3 = 1/6
2. 4/5-2/3 = 2/15
3. 4/15-1/10 = 1/30
When adding or subtracting fractions with unlike denominators, the first step is to convert the fractions so that they have a common denominator. To do this, you can use the lowest common denominator, which is the least common multiple of the denominators. For example, in the first problem, the least common multiple of 3 and 2 is 6, so you can convert the fractions to 2/6 and 4/6, or 1/3 and 2/3. Then, you can add or subtract the fractions as normal. For example, 1/3+2/3 would equal 3/3 or 1.
For subtracting fractions with unlike denominators, the same process is used. For example, in the second problem, the least common multiple of 5 and 3 is 15, so you can convert the fractions to 4/15 and 2/15. Then, you can subtract the fractions as normal. For example, 4/15-2/15 would equal 2/15.

alex earns a $35,000 salary in the first year of his career. each year, he gets a 3% percent raise. which expression gives the total amount alex has earned in his first n years of his career?
After n years Alex will earn salary which can be expressed as $(1 + 0.03)^n * 35,000.
The total amount Alex has earned in his first year of his career is $35,000.
In the second year of his career, he gets a 3% raise, which is an increase of 3/100 * $35,000 = $1,050.
So his salary for the second year is $35,000 + $1,050 = $36,050.
In the third year of his career, he again gets a 3% raise, which is 3/100 * $36,050 = $1,081.50
So his salary for the third year is $36,050 + $1,081.50 = $37,131.50
We can see that for each year, his salary is increasing by a fixed percentage of the previous year's salary.
This pattern can be represented by the expression:
(1 + 0.03)^n * 35,000
Where n is the number of years since the start of his career. This expression gives the total amount Alex has earned in his first n years of his career.

Step-by-step explanation:
First you have to graph your y-intercept (1) *which is the red dot in the graph I made for you*
Then you must use your slope (-2) to graph the rest
Since your slope is negative you have to go down from your y-intercept. In your case you are going down 2 units from your intercept. And since your slope is a whole number instead of a fraction you just go to the right 1 unit to make the coordinate (1,-1).
That is how you graph your equation.
