Hello there! Your answer would be y = 0.5x - 3.
To find the equation, use slope intercept form, y = mx + b. <em>(m = slope, b = y intercept)</em>
For the slope, solve by subtracting the y values over the x values.
- 5 - - 3 / 0 - 4
- 2 / - 4
The negatives cancel out, and you are left with 0.5 as your slope. Plug that into m.
y = 0.5x + b
Now to find the y intercept. To do this, we can replace the x and y values into the equation and solve for b.
-5 = 0.5(4) + b
-5 = 2 + b
- 3 = b
so, the y intercept has a value of -3. Plug that in to the final equation.
y = 0.5x - 3
Hope this helps and have a great day!
Answer:
2
Step-by-step explanation:
29 % 3 = 9
3x9 = 27
29 - 27 = 2
Oh ok so square root of 2 is irrational since it goes on and on. square root of 18 is an irrational number too
Answer:
16. D
17. 5^-1 · 5^-1 and 25^-1
8^0 · 8^3 and 8^3
Step-by-step explanation:
When you multiply two same numbers with exponents, just think of it as adding up exponents.
When you divide two same numbers with exponents, just think of it as subtracting exponents.
If a parenthesis has an exponent outside, then every exponent inside the parenthesis will be multiplied by that outside parenthesis.
(5^-1)^-2 · 5^3 ÷ 5^7
5^2 · 5^3 ÷ 5^7
5^5 ÷ 5^7
5^-2
When exponents are negative, you have to flip them or put them on the other side
5^-2 = 1/5^2 = 1/25
Let's try to find the equivalent pairs
6^7 ÷ 6^-2 = 6^5
6^9 = 6^5 Not equivalent
(6^3)^0 = 6
6^0 = 1 (Any number with a zero exponent is always 1)
1 = 6 Not equivalent
5^-1 · 5^-1 = 25^-1
5^-2 = 25^-1
Flip em
1/5^2 = 1/25
1/25 = 1/25 Equivalent
8^0 · 8^3 = 8^3
8^3 = 8^3 Equivalent
4^-3 ÷ 4^2 = 4^5
4^-5 = 4^5 Not equivalent
