A'(1, -4)
B'(3, 2)
C'(4. -2)
Step-by-step explanation:
Given
Triangle ABC with coordinates
A(1, 4), B(3, -2), C(4, 2)
To find
Coordinates of the image A'B'C' after a reflection over the x-axis
Solution
Rule for reflection over x-axis is
R(x) = (x, y) → (x, -y)
The coordinates will change as follows
A(1, 4) → A'(1, -4)
B(3, -2) → B'(3, 2)
C(4, 2) → C'(4. -2)
The 40-ft-long A-36 steel rails on a train track are laid with a small gap between them to allow for thermal expansion. Determine the required gap d so that the rails just touch one another when the temperature is increased from T1=-20F to T2=90F. Using this gap, what would be the axial force in the rails if the temperature rises to T3=110F? The cross-sectional area of each rail is 5.10 in2

Solve 2х + 4 > 16.
А. x> 6
В. x<10
C. x> 10
D. х< 6
Answer:
The answer is x > 6.
Reasoning:
2x + 4 > 16You have to subtract 4 from both sides:2x + 4 > 16
-4 > -4
2x > 12
16 subtract from 4 is 12. You then divide the 12 by the 2.2x > 12
2 2
x > 6
You then get the result of x > 6.1.49

I need help finding the slope, the y-intercept and the equation?
Answer:
y is (0,-2) thats all i know sorry
Step-by-step explanation:
The equation of line will be;
⇒ y = x + 2
And, The y - intercept will be 2.
What is Equation of line?
The equation of line with slope 'm' and y - intercept at point 'b' is given as;
⇒ y = mx + b
Given that;
The points on the graph are (0, 2) and (- 2, 0).
Now,
Since, The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope 'm' is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Thus, The slope of the line with the points (0 , 2) and (-2, 0) is;
m = (0 - 2) / (- 2 - 0)
m = - 2/- 2
m = 1
So, The equation of line passing through the points (0 , 2) and (-2, 0) with slope 1 is defined as;
y - y₁ = m (x - x₁)
y - 2 = 1 (x - 0)
y - 2 = x
y = x + 2
Now, Compare with the equation y = mx + b, we get;
The y - intercept = 2
Thus, The equation of line will be;
⇒ y = x + 2
And, The y - intercept will be 2.

What does f(1) represent in a sequence?
Answer: First term.
Step-by-step explanation:
An ordered list with a pattern is known as a sequence.It is denoted by [tex]<f(n)>[/tex] or [tex]<a_n>[/tex], where n is any natural number.i.e. Domain for this function is natural number.
Natural number starts with 1.
so, at n=1 f(1) represents the first term in a sequence.
Hence, f(1) represents "first term" in a sequence

if f(x)=3x+23, find the value of x so that f(x)=36
with steps please!
Answer: f(36)=131
Step-by-step explanation:
f(x)=3x+23
f(36)=3(36)+23
f(36)=108+23
f(36)=131
Answer:
131
Step-by-step explanation:
f(x)=3x+23 The first thing you do is plug in 36. so replace the X's with 36.
f(36)=3(36)+23 The second step is to multiple 3 times 36.
f(36)=108+23 The last step is to add 108 to 23.
