Answer:
5 + a
A: ---------
a - 1
Step-by-step explanation:
3+x 3 + a + 2
f(x) = ---------- becomes f(a + 2) = ------------------
x-3 a + 2 - 3
5 + a
when a + 2 is substituted for x. This last result simplifies to ------------
a - 1
which matches Answer A.
What is the equation of this graph?
Answer (assuming it is allowed to be written in slope-intercept form):
[tex]y = -\frac{2}{3} x + 1[/tex]
Step-by-step explanation:
When knowing a line's y-intercept and its slope, you can write its equation using slope-intercept form, or [tex]y = mx + b[/tex].
1) First, find the slope of the line. Read the graph and look at the two points marked on the line - they are (0,1) and (3,-1). Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] , substitute the x and y values of those points, and solve:
[tex]\frac{(-1)-(1)}{(3)-(0)} \\= \frac{-1-1}{3-0} \\= \frac{-2}{3}[/tex]
Thus, the line's slope is [tex]-\frac{2}{3}[/tex].
2) Now, use the slope-intercept formula, [tex]y = mx + b[/tex], to write an equation. Substitute the [tex]m[/tex] and [tex]b[/tex] for real values.
The [tex]m[/tex] represents the slope, so substitute [tex]-\frac{2}{3}[/tex] in its place. The [tex]b[/tex] represents the y-value of the y-intercept, or the point at which the line crosses the y-axis. Looking at the graph, we can see that the line intersects the y-axis at (0,1). Thus, substitute 1 for [tex]b[/tex]. This gives the following equation and answer:
[tex]y = -\frac{2}{3} x + 1[/tex]

Answer:
slope is 2/3
Step-by-step explanation:
To solve for slope: y2-y1 / x2- x1.
Two points can be (0,50) and (30,70) since they intercept.
70-50 / 30- 0 = 20/30 = 2/3.
The slope is also going 20 units up and 30 units across which gives you 2/3.

Option (A)
Given expression [tex]\sqrt{\frac{x^2+2x-5}{2x^2-3x+4}}[/tex] can't be written in the form of a fraction [tex](\frac{p}{q})[/tex] (Without square root).
Therefore, given function is not a rational function.
Rest all options represent a rational function.
Option A will be the answer.
The length of a diagonal of a square is 10 square root of 2 inches. Find the length of one side of the square.
Answer:
10inches
Step-by-step explanation:
Let the length of one side of the square be a
If the diagonal of a square is 10√2 inches
According to pythagoras theorem
a²+a² = (10√2)²
2a² = 100(2)
2a² = 200
a² = 200/2
a² = 100
a = √100
a = 10
Hence the length of one side of the square is 10inches

Devon has been saving $5 & $10 for the past four years. Over spring break he wanted to see how much money he has saved up. After counting the money he calculated that he has a total of $395 & had 49 bills. Based on this information, how many $5 & $10 bills does he have?
Answer:
19 five dollar bills
30 ten dollar bills
Step-by-step explanation:
x=number of $5 bills
y=number of $10 bills
x+y=49
x=49-y
5x+10y=395
substitute for x
5(49-y)+10y=395
245-5y+10y=395
245+5y-245=395-245
5y=150
5y/5=150/5
y=30
x=49-30=19

The value of x would be 75 degrees beacuse of corresponding angles on the same line of tranversal.
What are corresponding angles?In literal sense, corresponding means pair wise angles. Like the right corner angles of two triangles etc. But usually we take them as: For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of same measurement.
Given that AD and EH are parallel lines
So Angle GFE is equals to angle FBA.
And angle CBA equals to 180°
Angle FBA = 180°-105°
Angle FBA = 75°
Hence, The value of x would be 75 degrees beacuse of corresponding angles on the same line of tranversal.

well you use pythagorean theorem
12 × 3
=36
16 × 3
=48
pythagorean theorem states that:
a²+b²=c²
so
48² + 36² =3600
then, because c is squared, you just square root it
√3600 = 60
