Answer:
− 108 x 5 y 7
Step-by-step explanation:
My computer wont allow it but the 5 and the 7 are exponents
Answer:
[tex]-108x^{5}y^{7}[/tex]
Step-by-step explanation:
Simplify using the laws of exponents (there are more rules than listed, these given rules are just the ones that come into play here);
- when there is a term in parenthesis with an exponent outside, the term's exponent gets multiplied by the exponent outside
- when multiplying two exponents, one can only combine terms with the same base, and one must add the exponents
[tex](3xy^{2})^{3}*(-4x^{3}y)\\\\=(3^{3}*x^{3}*y^{2{^{3}}}) *(-4x^{2}y)\\\\=(27x^{3}y^{6})(-4x^{2}y)\\\\=-108x^{5}y^{7}[/tex]

Amanda plans on going to the amusement park this Friday. It costs $25.00 to
enter the park, and then $1.25 for every ride that Amanda goes on. What will be
the total cost if Amanda goes on 9 rides?
Answer:
$36.25
Step-by-step explanation:
To enter the park, Amanda pays 25 dollars.
+$25
It costs 1.25 for every ride that Amanda goes on.
Since we don't know the number of rides Amanda goes on, we will add a variable to represent the number of rides.
1.25x
Then, the passage says that Amanda goes on 9 rides. So, substitute 9 for x.
Equation: 25+1.25(9)
Then solve:
$36.25
What is 5x - 3y when x equals negative 2 and Y equals 6
Answer:
-28
Step-by-step explanation:
We have the equation [tex]5x-3y[/tex] and are given that [tex]x=-2, y=6[/tex]. To solve this equation, we simply replace the variables with their real value. In action, this would be [tex]5(-2)-3(6)=-10-18=-28[/tex].

O Right 3 Up 4
Left 3. Up 4
Down 3. Right 4
O Up 3 Right 4
Answer:
3 down, 4 up
Step-by-step explanation:
-3 is the X line, which starts on 0, if you subtract 3, or add -3, you would have to go down, 3 down. 4 is on the Y line, so you add, go left to add on the Y line, 4 up.
Always start with you X coordinate. Here is a tip to help you (X, Y)

Please help me
Answer:
C) -7/3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-(-5))/(-2-4)=(9+5)/-6=14/-6

What is the Area of 28in circle rounded to the nearest hundred
Answer:
The circumference is similar to the perimeter in that it is the total length needed to draw the circle.
We note the circumference as c.
c = 2πr
or
c = πd
This depends on whether or not you know the radius (r) or the diameter (d)
Let’s calculate one manually, for example.
If r = 6 cm, then the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.
Suppose you only know the diameter? If the diameter is 8 cm, then the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth.

System of equations!!!
Answer:
Step-by-step explanation:
1. x^2-x-20=3x-15
x=5, x=1 substitute
y=3*5-15 = 0
y=3*(-1)-15 = -18
Solution: (5,0) & (-1,-18)
2. x^2+2x+3=x+5
x=-2, x=1 substitute
y= -2+5 = 3
y=1+5 = 6
Solution: (-2,3) & (1,6)
A bicycle shop normally sells for 569.99. it is now on sale for 30% off. As an employee. Johnny is able to save an extra 15% off the sale price. How much, to the nearest dollar, would Johnny need to pay for the bicycle?
Answer:
$339.14
Step-by-step explanation: 569.99 * 30%=171.
569.99-171.=398.99
398.99*15% = 59.85
398.99-59.85=339.14

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
What is LCM?It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
The GCF of 14x and 18xy
As we know, GCF is the greatest common factor.
The greatest common factor of 14 and 18 or
GCF(14, 18) = 2
And the greatest common factor of GCF of x and xy
= x
the greatest common factor of 14x and 18xy is:
= 2x
Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
