7 4K ≡ ________________ (mod 100 )
(a ) 4
(b ) 2
(c) 3
( d ) 1
I assume you're asked to find [tex]7^{4k}\pmod{100}[/tex] for positive integer k. To start, notice that
[tex]7^4 \equiv 7^3\times7 \equiv 343\times7 \equiv 43\times7 \equiv 301 \equiv 1\pmod{100}[/tex]
Then for every k, we have
[tex]7^{4k} \equiv (7^4)^k \equiv 1^k \equiv 1 \pmod{100}[/tex]

Questions 10-12
f(x)= 3x-13
g(x)= 2x^2-4x-5
h(x)=4^x-7
10. Find (f - g) (x)
11. Find (f - h) (x)'
12. Find (f + g) (x)
(f–g)(x)= (3x-13) – (2x²–4x–5)= –2x²+7x-8
(f–h)(x)= (3x-13) – ( 4^x –7) = 3x – 4^x–6
(f+g)(x)= (3x-13) + (2x²–4x–5) = 2x²–x – 18

answer choices
A. (-5, 2)
B. (5, 2)
C. (2, -5)
D (-2, 5)
Answer:
The correct choice is option B. (5, 2)
Step-by-step explanation:
The rotation rule of 180° is = (x ,y) -> ( -x , -y) .
Coordinates of C before the rotation are ( -5 , -2) so according to the rule above they will now be = C'( 5 , 2 ) .
Therefore, the ordered pair for C' is (5, 2) after the 180 degrees rotation.
6x+6=-5+3x+17
I need help
Answer:
Get all the terms with x on the left. Get all the terms without x on the right. Simplify by adding and subtracting the terms without x and adding and subtracting the terms with x. Finally divide to get the value of x.
Step-by-step explanation:
6x+6 =- 5+3x+17
6x+6 -6 =- 5+3x+17 -6
6x = 5+3x+11
6x = 3x + 16
6x - 3x = 3x + 16 -3x
3x = 16
3x / 3 = 16 / 3
x = 15/3 + 1/3
x = 5 1/3
x = 5.33333...

a shea cd player costs $80 last year and $112 this year. what was the percent of increase in its price
Answer:
40% increase
Step-by-step explanation:
c = final value - initial value

112 - 80 = 32
32 / 80 = 0.4
0.4 = 40%
Pls help I need it I’m really confused
The equations are alike because all of their variables are equivalent to 6. Another similarity is that they are all one-step equations, meaning they can be solved with just one operation.
[tex]4a=24\\a=6[/tex]
[tex]c-1.2=4.8\\c=6[/tex]
[tex].5b=3\\b=6[/tex]
[tex]d + 5.5=11.5\\d=6[/tex]
These equations are different because require different operations to find their variables. Their terms, excluding the variable, also have differnt values.

9d^ 2 - 27d^ 5 + 45d^ 3
Answer:
Below.
Step-by-step explanation:
The GCF of 9 , 27 and 45 = 9.
GCF of the d terms is d^2.
So the GCF of the whole expression is 9d^2.
Factors are 9d^2( 1 - 3d^3 + 5d)

I need help on this problem
Answer:
x 1 / 2 / 3 / 4 / 5
y -3 / 3 / 11 / 21 / 33
you can figure this put by just putting the equation above in a calculator and replacing all the x's with numbers and press equal the answer is y
example
1^2 + 3(1) -7 = -3
x= 1
y=-3
and you can use those coordinates to graph them

Anthony travels 48 miles by car in the same time it takes him to travel 12 miles on his
bike. His average rate of speed by car is 24 miles per hour faster than his average rate of speed by bike. What is the average rate of speed for both the car and the bike?
Answer:
Anthony's average speed by car is 32 miles per hour and his average speed by bike is 8 miles per hour.
Step-by-step explanation:
Let the average rate (in miles per hour) at which Anthony travels by car be c and by bike be b.
His average rate of speed by car is 24 miles per hour faster than his average rate of speed on bike. In other words:
[tex]c = b + 24[/tex]
Anthony travels 48 miles by car in the same amount of time it takes him to travel 12 miles by bike.
Recall that distance is given by the rate multiplied by the time t.
Hence, c multiplied by time t equals 48 miles:
[tex]\displaystyle ct = 48[/tex]
Likewise, b multiplied by the same time t equals 12 miles:
[tex]bt = 12[/tex]
Solve. We can multiply the second equation by four:
[tex]4bt = 48[/tex]
Substitute:
[tex]ct = 4bt[/tex]
Divide:
[tex]c = 4b[/tex]
Since c = b + 24:
[tex](b + 24) = 4b[/tex]
Solve for b. Subtract:
[tex]24 = 3b[/tex]
And divide:
[tex]b = 8\text{ miles per hour}[/tex]
Hence, Anthony bikes at an average rate of 8 miles per hour.
Since his average speed by car is 24 miles per hour faster, his average speed by car is 32 miles per hour.
In conclusion, Anthony's average speed by car is 32 miles per hour and his average speed by bike is 8 miles per hour.

We know that corresponding angles of similar figures are congruent. Based on this example, are corresponding sides of similar figures always congruent?
Answer:
no
Step-by-step explanation:
similar figures means that the corresponding angles are congruent and the corresponding sides are similar. this means if ABCD and EFGH are similar, A=E*x, B=F*x, C=G*x, and D=H*x, so they aren't congruent
