Answer:
Step-by-step explanation:
Simplifying
2x + 4y = 13
Solving
2x + 4y = 13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
2x + 4y + -4y = 13 + -4y
Combine like terms: 4y + -4y = 0
2x + 0 = 13 + -4y
2x = 13 + -4y
Divide each side by '2'.
x = 6.5 + -2y
Simplifying
x = 6.5 + -2y

10 is 2x 5
so
you need to do 2x8 for the answer. so Regina needs to chop 16 logs
Answer:
200π m²
Step-by-step explanation:
Lateral area of a cone = πrl
r = 8 m
l = 25 m
Plug in the values
Lateral area = π × 8 × 25
Lateral area = π × 200 = 200π m²
Answer:
exponential decay
Step-by-step explanation:
The function is in the form
y = ab^x where a is the initial value and b is the growth or decay rate
If b >1 then it is growth
b < 1 then it is decay
f(x) = 5(2/3)^x
a = 5
b = 2/3
2/3 <1 so it is decay
Answer: (4)
<em>4 Absolute vale means how many places a number is away from 0 "zero". The absolute value of </em><em>(-4)</em><em>, written as abs</em><em>(-4),</em><em> is equal to 4 because </em><em>-4</em>
Step-by-step explanation:
To represent the absolute value of a number (or a variable), we write a vertical bar on either side of the number. For example, the absolute value of 4 is written as |4|.
Also, the absolute value of -4 is written as |-4|. As we discussed earlier, the absolute value results in a non-negative value all the time.
