Two equations are given below:

vovikov84 [41]

You can fill the second in in the first to get an equation with only b:

(b-2) - 3b = 22 =>

-4b-2 = 22 =>

-4b = 24

b = -6

a = -6-2 = -8

So (-8,-6) is the answer.

Anyone wanna help me

EleoNora [17]

$\huge\text{Hey there!}$

$\mathsf{4(3 + 5) - 3\times9^2}$

$\mathsf{3 + 5 = \bf 8}$

$\mathsf{4(8) - 3\times 9^2}$

$\mathsf{4(8) = \bf 32}$

$\mathsf{32 - 3\times9^2}$

$\mathsf{9^2 = 9\times9 = \bf 81}$

$\mathsf{32 - 3\times 81 }$

$\mathsf{-3\times81 =\bf -243}$

$\mathsf{32 - 243}$

$\mathsf{= \bf -211}$

$\boxed{\huge\text{= \bf -211}}$

$\boxed{\boxed{\mathsf{OVERALL\ ANSWER: \bf 4(8) - 3 \times 81 \rightarrow }\huge\text{\bf Option C}}}\huge\checkmark$

Answer:

The interval [25, 35] has the slowest average rate of decay.

Step-by-step explanation:

The number of grams in a sample of radium is represented by the function $r(t) = 50\cdot e^{-0.013\cdot t}$ , which is a monotonous decreasing function. Hence, the greater the values of $t$ , the slowest the average rate of decay, represented by a secant line. The interval [25, 35] has the slowest average rate of decay.
