Answer:
-12.8x - 20y + 8.4
Step-by-step explanation:
To do this you just multiply everything by negative 4
so we have 3.2x*-4 + 5y*-4 - 2.1*-4
This gives us
-12.8x - 20y + 8.4
The last term is positive because we multplied a negative by another negative
Answer:
I would choose either A.x 22 or D. infinitely many solutions
Step-by-step explanation:
Since you did put the answer choice B then I don't know what are all the possible answer choices
They are usually represented like this
commutative property of addition
a+b=b+a
associative property of additon
(a+b)+c=a+(b+c)
identity property of addition
a+0=a
so number sentatnces
lets say a=1,b=2,c=3
commutative property of addition
1+2=2+1
associative property of addition
(1+2)+3=1+(2+3)
identity property of addition
1+0=1
<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2
So, the answer is "A"
And we can test this with a square, sum of angles = 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct

Answer: Yes
Step-by-step explanation:
Though x and y can be achieved in a system of equations. The equation
x (t)=0.0411905(t^2)+(-0.164619)t+28.0114
And
y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)
Are not system of equations but rather two different models of equations. Nevertheless
To find t in the first equation, x(t) has to be equal to zero.
When the t is substituted in the second equation, t will completely disappear. Given the value of y(t) and vice versa.
