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

Wht is 84 is 74% of what number
Elina [12.6K]
'is' in mathematics means equal
'of' in mathematics means multiplication

percent means over 100

84 = 74% * x

84 = 74/100 * x

84 = 37/50 * x

Multiply 50/37 on both sides, so we can isolate 'x'

85 * 50/37 = x

x = 4250/37

x ≈ 114.864865

84 is 74 percent of <span>114.86</span>.
