Answer:
- 3/5
Positive
Step-by-step explanation:
when plotting on a number line, you will start with the first term listed in the equation, in this case it is -3/5
then, if the next term is positive, you will move to the right (aka positive direction), but if the next term is negative then you will move to the left (aka negative direction)
in this question, the next term is positive, so you will move in the positive direction

a two-digit number is equal to 8 times the sum of its digits
Answers
10x-y=8(x+y)
how can we show that the numbers digits are reversed using our variables? the numbers digits being reversed means that the digit that was in the tens place is now in the ones place and vise versa. so the reversed digit number would look like this: 10y+x
(10x+y)-45=10y+x
now you can solve the system of equations.
10x+y=8(x+y)
solve for one variable, i’ll choose x
2x=7y
x=7/2y, or 3.5y
(10x+y) - 45= 10y+x
go to your second equation
(10•3.5y+y)-45=10y+3.5y
plug in for x
36y-45=45
y=2
x=3.5y go back to the equation where you solved for c in terms of y
x=3.5(2)
plug in for y
x=7
the number is 72
let’s check
1. 72=8(7+2)
72=8(9)
72=72
2. 72-45= 27
27=27

Answer:

Step-by-step explanation:
We can use pythagoras to solve this:
Distance along x = 3 (side a)
Distance along y = 4 (side b)
Pythagoras theorem states that: a² + b² = c²
Therefore 3² + 4² = c²
9 + 16 = c²
25 = c² (square root on both sides to get c)
√25 = c
5 = c
Find the values of a and b given that the polynomial P(x) = x^3+ ax^2 +x+b, is divisible by
both x-1 and x + 3.
Answers
Answer:
a=4
b=-6
Step-by-step explanation:
If P(x) is divisible by x-c, then P(c)=0.
So P(1)=0 implies 1^3+a1^2+1+b=0
and
P(-3)=0 implies (-3)^2+a(-3)^2+-3+b=0
So notice we have a system to solve.
Let's simply it.
First equation:
1^3+a1^2+1+b=0
1+a+1+b=0
2+a+b=0
a+b=-2
Second equation:
(-3)^3+a(-3)^2+-3+b=0
-27+9a-3+b=0
9a+b-30=0
9a+b=30
Let's put our system together:
a+b=-2
9a+b=30
This is setup so if we subtract the equations b will eliminate allowing us to solve for a:
-8a=-32
a=4
If a=4 and a+b=-2, then 4+b=-2 giving us b=-6.
a=4
b=-6

If you look at the image, look where x equals -9. Look at what points are on that line called x=-9. We see the x=-9 line intersects the blue line system at (-9,1). We now know that the y output for x input being -9, is 1.

² x 160 qx x ✓
Answers
Answer:q = - 9 and r = - 10
Step-by-step explanation:
since g(x) is divided by (x - 1) with remainder - 12, then (1) = 4(1)³ + q(1)² + r + 3 = - 12, that is 4 + q + r + 3 = - 12
q + r + 7 = - 12 ( subtract 7 from both sides )
q + r = - 19 → (1)
Since (x - 3) is a factor of g(x), then
g(3) = 4(3)³ + q(3)² + 3r + 3 = 0, that is
108 + 9q + 3r + 3 = 0
9q + 3r + 111 = 0 ( subtract 111 from both sides )
9q + 3r = - 111 → (2)
The 2 equations to be solved simultaneously are (1) and (2)
Multiply (1) by - 3
- 3q - 3r = 57 → (3)
Add (2) and (3) term by term to eliminate r
6q = - 54 ( divide both sides by 6 )
q = - 9
Substitute q = - 9 into (1)
- 9 + r = - 19 ( add 9 to both sides )
r = - 10

Which is a perfect square?
6^1
6^2
6^3
6^5
Answers
Answer:
6^2
Step-by-step explanation:
6^2 because,
6^1 is not a perfect square because 6 is its own number because 6 x 1 =6 Therefore being eliminated.
6^3 is not a perfect square because 6 x 6 x 6 (216) is cubed not square
*This one almost tricked me*
6^5 is not a perfect square because 6 x 6 x 6 x 6 x 6 (7776) it isn't an equal factor combination, that when multiplied together, produce the number 7,776. That means 7,776 is not a perfect square.
6^2 is a perfect square because 6x6= 36 and 36 is a perfect square.
Therefore, its 6^2

Now for decimals it goes in the order of tenths, hundredths, thousandths, etc.
We have 21 thousandths
it would end up looking like this
121.021
The 0 is relevant due to the the fact the decimal is suppose to be 21 thousandths.
