Step-by-step explanation:
how do you find the slope of (2,20)(4,40)(6,60)
9514 1404 393
Answer:
slope = 10
Step-by-step explanation:
Examination of the values shows you that each y-value is 10 times the corresponding x value. That means the slope is 10. (If the ratios were different, then the slope formula would need to be used. The fact that they are all the same means y is proportional to x.)
__
You can use the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (40 -20)/(4 -2) = 20/2
m = 10
The slope is 10.
F(x) = 4x+3x
g(x) = 2x-5
7. Find (f+9) (x)
8. Find (f - g) (x)
Answer:
7. [tex](f+g)(x) = 6x - 2[/tex]
8. [tex](f-g)(x) = 2x + 8[/tex]
Step-by-step explanation:
We are given two function, f(x) and g(x).
We want to find their addition and their subtraction, and we do this combining like terms.
The functions are:
[tex]f(x) = 4x + 3[/tex]
[tex]g(x) = 2x - 5[/tex]
7. Find (f+9) (x)
[tex]4x + 3 + 2x - 5 = 4x + 2x + 3 - 5 = 6x - 2[/tex]
So
[tex](f+g)(x) = 6x - 2[/tex]
8. Find (f - g) (x)
[tex]4x + 3 - (2x - 5) = 4x + 3 - 2x + 5 = 4x - 2x + 3 + 5 = 2x + 8[/tex]
So
[tex](f-g)(x) = 2x + 8[/tex]

Hope this helps
can you please help and explain how to do this
Answer:
x = -3
Step-by-step explanation:
Notice that the addition of angle <CDH plus angle <HDE have to give the measure of angle <CDE (which is 144 degrees as stated in the problem)
Then, we can say in equation form:
<CDH + <HDE = 144
replacing with their expressions in terms of x:
x + 93 + 57 + x = 144
solving for x:
2 x + 150 = 144
2 x = 144 - 150
2 x = - 6
x = -3

if the domain of the coordinate transformation f(x,y)=(y+2,-x-4) is (1,-4),(3,-2), (0,-1)
Answer:
The Fundamental Graphing Principle for Functions says that for a point (a, b) to be on the graph,
f(a) = b. In particular, we know f(0) = 1, f(2) = 3, f(4) = 3 and f(5) = 5. Suppose we wanted to
graph the function defined by the formula g(x) = f(x) + 2. Let’s take a minute to remind ourselves
of what g is doing. We start with an input x to the function f and we obtain the output f(x).
The function g takes the output f(x) and adds 2 to it. In order to graph g, we need to graph the
points (x, g(x)). How are we to find the values for g(x) without a formula for f(x)? The answer is
that we don’t need a formula for f(x), we just need the values of f(x). The values of f(x) are the
y values on the graph of y = f(x). For example, using the points indicated on the graph of f, we
can make the following table.
x (x, f(x)) f(x) g(x) = f(x)
In general, if (a, b) is on the graph of y = f(x), then f(a) = b, so g(a) = f(a) + 2 = b + 2. Hence,
(a, b+ 2) is on the graph o
main role x (x, f(x)) f(x) g(x) = f(x) + 2 (x, g(x))

(Guys I really need help with this one question) FGHIJ ~ YUVWX. Find UY and GH.
Answer:
UY = 90
GH = 4
Step-by-step explanation:
Property of similarity of two similar figures:
"If two figures are similar, their corresponding sides are proportional"
Since, FGHIJ ~ YUVWX
[tex]\frac{FG}{UY}= \frac{GH}{UV}= \frac{IJ}{WX}[/tex]
[tex]\frac{10}{UY}= \frac{GH}{36}= \frac{6}{54}[/tex]
[tex]\frac{10}{UY}= \frac{6}{54}[/tex]
UY = [tex]\frac{54\times 10}{6}[/tex]
UY = 90
[tex]\frac{GH}{36}= \frac{6}{54}[/tex]
GH = [tex]\frac{6\times 36}{54}[/tex]
= 4
GH = 4
