Answer:I don't know all of them but for G. the answer is j= any number -5 and higher hope this helps!!
Step-by-step explanation:
Y = x2 – 3x – 10
roots are x intercepts on form of (x,0)
Let's solve the quadratic equation
y = x2 – 3x – 10
(x-5)(x+2)
x=5,-2
roots: (5,0)(-2,0)
let's see of these are correct
y = x2 – 3x – 10
y=(5)^2-3 (5)-10
y=25-15-10
y=10-10
y=0
y = x2 – 3x – 10
y=(-2)^2-3 (-2)-10
y=4+6-10
y=10-10
y=0
the roots are correct
Answer: 9
Step-by-step explanation:
Hi!
This question is worded a little funny, but i think in understand what it's asking. Forgive me if i'm wrong.
Place values in math are pretty self-explanatory. It's just asking you what place each number is in.
For example:
If you were to write the number 12, the 1 would be in the tens place and the 2 would be in the ones place.
When speaking about decimals, you pretty much just have to add the letters 'th' to the end of the place value, but instead of decreasing as the numbers grow smaller, you increase and the ones place doesn't exist.
So in this case:
With 249.637, 2 is in the hundreds place. 4 is in the tens place. 9 is in the ones place. 6 is in the tenths place. 7 is in the hundreths place. 3 is in the thousandths place.
Hope this helps :)
When you multiply two numbers, let’s say x and y, there are no negatives, so you know that it is positive. So that means it’s xy. Now, imagine we make that a -x times y. Since there is only 1 negative, it is negative. So that would be -xy. Now, imagine you have -x times -y. Since there are an even number of negatives, they cancel out!! (Magic). So -x times -y is xy.
