Answer:
A) X=3
Step-by-step explanation:
If x=y then x is the same value as y.
So if y=3, the x must also equal 3.
Consider this system of equations.
f(x)=x−4g(x)=−x−2
Plot the point that represents the solution to the equation f(x)=g(x).
We are given two functions.
[tex]f(x)=x-4\\g(x)=-x-2[/tex]
The point that represents the equation [tex]f(x)=g(x)[/tex], will also be the intersection of those two lines, meaning we can set the two equations equal to each other and solve for [tex]x[/tex].
[tex]f(x)=g(x)\\x-4=-x-2\\2x=2\\x=1[/tex]
Now that we are given the x value, we can plug this value back into either equation and solve for the y value.
[tex]f(1)=1-4\\f(1)=-3[/tex]
The point of intersection will be [tex](1,-3)[/tex].
Hope this helps!
Answer:
x=-1
Step-by-step explanation:
x-4=-x-2
x+x=-2+4
2x=-2
x=-1
Find the linear function for F in terms of H
Answer:
F = -20h + 450
Step-by-step explanation:
To find the linear function, we will use the coordinate points (1, 430) and (2, 410)
Get the slope;
m = ΔF/Δh = 410-430/2-1
m = -20/1
m = -20
Get the y intercept b
Substitute m = -20 and (1, 430) into y = mx+b
430 = -20(1) + b
430+20 = b
450 = b
Swap
b = 450
Get the required equation
y = -20x + 450
replace x with h and y with F
F = -20h + 450
Hence the required equation is F = -20h + 450

How would I simplify x+2y<4 so I can graph it
Answer:
y < -1/2x + 2
Step-by-step explanation:
x+2y<4
subtract x from both sides
2y<-x+4
then divide both by 2
y< -1/2+2

two times the sum of a number and 18 is at least -21
Answer:
2x + 18 ≥ 21
x ≥ 2/3
Step-by-step explanation:
Let sum be X
2 times the sum means 2x
the sum of a number and 18 means x + 18
at least -21 means ≥ 21
put them together, and you get, 2x + 18 ≥ 21
If solving for x,
2x + 18 ≥ 21
2x ≥ 3
x ≥ 2/3

In triangle ABC below , which is the longest side?
Answer:
the longest side is AC
Step-by-step explanation:
The longest side will be opposite the largest angle.
4x+(2x-6) + (4x-4) = 180 (all triangle interior angles add up to 180 degrees)
simplify:
10x - 10 = 180
10x = 190
c= 19
angle B = 4(19) = 76 degrees
angle A = 2(19) - 6 = 32 degrees
angle C = 4(19) - 4 = 72 degrees
so the longest side is AC

A factory can build 15 cars every hour. If at a certain time of day , they have already built 9 cars,how many cars in total will they have built 5 hours from now?
Answer:
They would have built 84 cars
Step-by-step explanation:
From the question, they have already built 9 cars
Now, the hourly production rate is 15 cars per hour;
So therefore, in 5 hours, total that would have been built excluding the initial 9 will be;
15 * 5 = 75 cars
Now, let us add the initial 9
we have this as 9 + 75 = 84 cars

hello : here is an solution
At a water park there is a slide that you really want to ride. In order to get to the top of the 29 foot slide you must first climb a ladder. When you finish the ride you end up 21 feet from the base of the ladder. How tall is the ladder you must climb in order to get to the top
Answer: 20 feet
Step-by-step explanation:
This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.
Solve with Pythagoras rule:
c² = a² + b²
c = hypotenuse
a= length
b = height
29² = 21² + b²
841 = 441 + b²
b² = 841 - 441
b² = 400
b = √400
b = 20 feet

Find the missing side length.
Assume that all intersecting sides meet at right angles.
Be sure to include the correct unit in your answer.
Answer:
the answer is 12 yd if you are talking about the question mark.
Step-by-step explanation:
Well, if you split this figure into two rectangles, then the 16 yd length becomes 12 yd because the one congruent to it is 4 yd. Both sides are congruent so you'd get 12 yd.
