How is the product of 2 and –5 shown using integer tiles? 2 positive tiles and 5 negative tiles. 2 negative tiles and 5 positive tiles. 5 negative tiles and 5 negative tiles. 5 positive tiles and 5 positive tiles.
Answers
Answer:
5 negative tiles and 5 negative tiles
Step-by-step explanation:
When multiplying a positive number by a negative number, the product is always negative.
This can be visualized using integer tiles:
Answer:
So lets say the negative tiles are red and the poiitive tiles are yellow.
Now for the first one
2*-5
That would be shown with two groups of fives with red tiles
Now we know its -10 be used if you count it up, its 10 negatives red tiles
-2*5
So 5 groups of 2 red tiles and if you count it all up, you’ll get -10
-5*-5
So 5 groups of -5 tiles
You’d get -25
But thats not the answer
I have no clue to show this but i guess you just have to know that negative *negative is positive so just switch the signs
25
5*5
Just make 5 groups of 5 yellow tiles and count them up, you’ll get 25

B) [tex]9d^8[/tex]
Step-by-step explanation:
To find the expression equivalent to [tex](3d^4)^2[/tex], we must simplify the given expression. This can be done by applying an exponent rule:
[tex](a*b)^x=a^xb^x[/tex]
In the context of our problem, we would have:
[tex](3*d^4)^2[/tex]
Therefore, when that exponent is distributed, we get:
[tex](3^2d^8)[/tex]
Simplified, we have:

The variables x an y vary directly. When x=13, y=52. Which equation correctly relates x and y?
Answers
Answer:
The equation which correctly relates x and y is y = 4x
Step-by-step explanation:
The equation of the direct variation is y = k x, where
k is the constant of variationTo find the value of k, use the initial values of x and y∵ The variables x and y vary directly
→ Use the form of the equation above
∴ y = k x
∵ When x = 13, y = 52
→ That means the initial values of x and y are 13 and 52
∴ x = 13 and y = 52
→ Substitute them in the equation above to find k
∵ 52 = k (13)
∴ 52 = 13k
→ Divide both sides by 13
∴ 4 = k
∴ The value of k is 4
→ Substitute it in the equation
∴ y = 4x
∴ The equation which correctly relates x and y is y = 4x
Charles wants to compare the solutions to the equations x^2=64 and x^3=64.
Compare the signs of the solutions. Explain your reasoning.
Answers
Answer:
x = ±4
x = 4
Step-by-step explanation:
x² = 64.
Square root both sides
√x² =√64
x= ±8
When squaring both sides, the required solution is both positive and negative since the product of two negative number is positive.
x³ = 63.
Cube root both sides
3√x³ = 3√65
x =4
This only gives a positive number not negative since the product of three negative number gives a negative number

Answers
Answer: B) 2/3
====================================================
Work Shown:
Method 1
Apply the slope formula
m = (y2-y1)/(x2 - x1)
m = (3-1)/(-1 - (-4)) ..... using the first two rows as points
m = (3-1)/(-1 + 4)
m = 2/3 is the slope
-----------------------------------
Method 2
Each time y goes up by 2, x goes up by 3.
For instance, the jump from y = 1 to y = 3 is "plus 2". At the same time, the jump from x = -4 to x = -1 is "plus 3".
We can then say
slope = (rise)/(run)
slope = (change in y)/(change in x)
slope = (y increase by 2)/(x increase by 3)
slope = 2/3
