For a given input value b, the function f outputs a value a to satisfy the following equation. 4a+7b=−52 Write a formula for ) f

Sergio [31]

Answer: Our required formula becomes :

$a=f(b)=-13-\frac{7}{4}b$

Step-by-step explanation:

Since we have given that

$4a+7b=-52\\$

We need to write a formula for f(b) in terms of b So, it becomes

$4a=-52-7b\\\\a=\frac{-52-7b}{4}\\\\a=\frac{-52}{4}-\frac{7b}{4}\\\\a=-13-\frac{7b}{4}$

Hence, our required formula becomes :

$a=f(b)=-13-\frac{7}{4}b$

A bag contains yellow marbles and blue marbles, 37 in total. The number of yellow marbles is 7 more than 5 times the number of b

Mazyrski [523]

Answer:

Step-by-step explanation:

let b represent the number of blue marbles then

yellow = 5b + 7 and

b + 5b + 7 = 37, that is

6b + 7 = 37 ( subtract 7 from both sides )

6b = 30 ( divide both sides by 6 )

b = 5

Thus there are 5 blue and 5(5) + 7 = 25 + 7 = 32 yellow marbles

Graph the solution of the inequality on a number line. x − (5 − 3x) ≤ 2x − 1

egoroff_w [7]

Answer:

x ≤ 2

Step-by-step explanation:

x − (5 − 3x) ≤ 2x − 1
x - 5 + 3x ≤ 2x - 1
4x - 5 ≤ 2x - 1
4x - 2x ≤ 5 - 1
2x ≤ 4
x ≤ 2 or x ∈ (- oo, 2]

The graph includes all point to the left from point 2, same point included

Juan wants to find two numbers such that their sum is 33 and their difference is 13. The equations that will help him find the a

bija089 [108]

$2x - 13 = 33 \\ 2x = 33 + 13 \\ 2x = 46 \\ \frac{2x}{2} = \frac{46}{2} \\ x = 23$
33-23=10. 10+23=33. 23-10=13
the numbers are 23 and 10
