What is the slope of a line perpendicular to the line whose equation is x+y=5x+y=5. Fully simplify your answer.
Answer:
1
Step-by-step explanation:
x+y = 5
Put this equation in slope intercept form y = mx+b where m is the slope
y = -x +5
The slope of the line is -1
Perpendicular lines have slopes that multiply to -1
-1 * m = -1
m = 1
The slope of the perpendicular line is 1

Answer:
71. 19 72. 100 73. 9 74.1 75. 90 76. 4
Step-by-step explanation:
#71.
Start with 2b-a
Plug in the given numbers where the variables are.
Now the equation is 2(12) - 5
Solve 2(12) - 5
2(12) = 24 24 - 5 = 19
#72.
Start with d(ab-c)
Plug in the given numbers where the variables are.
Now the equation is 2((5×12) - 10)
Solve in the parenthesis first.
5×12= 60 60-10=50 2(50)= 100
#73.
Start with 3+ [tex]\frac{b}{d}[/tex]
Plug in the given numbers where the variables are.
Now the equation is 3+ [tex]\frac{12}{2}[/tex]
Solve.
[tex]\frac{12}{2}[/tex] = 6 3+6 = 9
#74.
Start with [tex]\frac{4a}{b+4d}[/tex]
Plug in the given numbers where the variables are.
Now the equation is [tex]\frac{4(5)}{12+(4x2)}[/tex]
Solve.
4(5)= 20
(4×2)= 8 12+8= 20
Now the fraction is [tex]\frac{20}{20}[/tex] = 1
#75.
Start with 2a² - c
Plug in the given numbers where the variables are.
Now the equation is 2(5)² - 10
Solve 2(5) = 10 10² = 100 100-10= 90
#76.
Start with b - c + d
Plug in the given numbers where the variables are.
Now the equation is 12 - 10 + 2
Solve.
12 - 10 = 2 2 + 2 = 4

Use the Table to evaluate each expression.
x | 1 2 3 4 5 6
f | 6 4 4 1 6 4
g | 5 5 2 1 4 3
a). f(g(1))
b). g(f(1))
c). f(f(1))
d). g(g(1))
e). (gof)(3)
f). (fog)(6)
Explain the concept and show step-by-step solution.
Here we have a problem of composition of functions.
Remember that:
(f ° g)(x) = f( g(x) )
Now we have the table:
x | 1 2 3 4 5 6
f(x) | 6 4 4 1 6 4
g(x) | 5 5 2 1 4 3
Using the table, we want to find:
To read the table, for example for f(5) first you go to the "x" part of the table and find the 5.
Now you go to the f(x) table and see which is the value of f(5), in this case, we can see that f(5) = 6.
a) f(g(1))
First, looking at the table, we can see that:
g(1) = 5
Then:
f(g(1)) = f(5)
Again, looking at the table we can see that f(5) = 6
Then we have:
f(g(1)) = 6
b) g(f(1))
Same approach as before:
f(1) = 6
then g(f(1)) = g(6)
And looking at the table, g(6) = 3
Then: g(f(1)) = 3
c) f(f(1))
f(1) = 6
f(f(1)) = f(6) = 4
f(f(1)) = 4
d) g(g(1))
g(1) = 5
then:
g(g(1)) = g(5) = 4
g(g(1)) = 4
e) (gof)(3)
This is equal to:
(gof)(3) = g(f(3))
we know that f(3) = 4
then:
g(f(3)) = g(4) = 1
(gof)(3) = 1
f) (fog)(6) = f(g(6))
We can see that:
g(6) = 3
then:
f(g(6)) = f(3) = 4
Concluding:
(fog)(6) = 4

Find the measure of the smaller angle formed by the hands of a clock at the following time.
1:25
The smaller angle formed by the hands of a clock at the following time.
1:25 is 42.5 degrees and 107.5 degrees
What is total angle of a circle?360 degrees
We need to find the angles of clock at 1:25
At 1:25, the hour hand has moved 85 out of 720 possible times from the top of the clock. 85 times 0.5 degrees is 42.5 degrees.
At 1:25, the minute hand has moved 25 out of 60 possible times from the top of the clock. 25 times 6 degrees is 150 degrees.
150 - 42.5 = 107.5 degrees
Therefore the smaller angle formed by the hands of a clock at the time 1:25 is 42.5 degrees and 107.5 degrees

A segment is simply the shortest distance between two points, For a line segment, it is the line which connects two points.
Given that :
LM = 22 ; MN = 15
The segment LN is defined as :
LN = LM + MN
LN = 22 + 15
LN = 37
2.)
LN = 54
LN = 54 LM = 31
The line segment, LN equals :
LN = LM + MN
54 = 31 + MN
MN = 54 - 31
MN = 23
3.)
DF = 9x - 39
DE = 47
EF = 3x + 10
The line segment, DF equals ;
DF = DE + EF
9x - 39 = 47 + (3x + 10)
9x - 39 = 47 + 3x + 10

Maggie's brother is 4 years younger than twice her age. The sum of their ages is 29.
How old is Maggie?
Maggie is____
years old.
Answer:
11
Step-by-step explanation:
You have to make a system of equations. So the first equation would be b=2m-4 (b is brother m is maggie). The next equation is 29=m+b (sum of their ages). Then you can use substitution so plug in 2m-4 for b in the second question. So it would be 29=m+2m-4. Simplify and solve for m and you get 11.
