10t+50=100
-50 -50
10t=50
10t/10=50/10
t=5
Answer:
No, this matrix is singular
Step-by-step explanation:
-1*-2*3=6
2*1*-2=-4
1*2*-1=-2
So, 6+(-4)+(-2)=0 -SINGULAR-
Answer:
Algebra Review: x=-4, r =5
Step-by-step explanation:
Use distributive prop;
-3x-6=6
then add 6 to both sides to get x by itself
you get -3x=12
divide both sides by -3
you get x=-4
Again do distributive prop.
-12r+24=-36
trying to get r by itself, so subtract 24 on both sides
you get: -12r=-60
then divide -12 both sides to get r by itself and you get r=5
Pythageron Theorem:
which is a^2+b^2=c^2
a=3, b=7 and c=C^2 (this is always the long side)
so then we get 3^2+7^2=c^2
9+49=c^2
opposite of sqaring is rooting
so we get sqare root of 58 or 7.6
I'm sorry I can't help you with the angles, I would suggest looking it up and Khan Acadamy is a good resource. Good Luck!
When you reflect over the y-axis, you negate the x coordinate and maintain the same y coordinate.
so (a,b) reflected over the y-axis would be (-a,b).
Assume the graduate put the purchase on his card.
then
Initial balance = $8000 on the first statement (+fees and interest charges, if any)
That means he owes the card issuer $8000.
Credit balance is what the issuer owes the card holder, which is zero.
