20 if f(x) = 4x + 5, what is the value of f(-3)? A-2 B-7 C 17 04

Juliette [100K]

Answer:

B. -7

Step-by-step explanation:

f(x) = 4x + 5

To find the value of f(-3), replace all the x's in f(x) with -3.

f(x) = 4x + 5

f(-3) = 4(-3) + 5

f(-3) = -12 + 5

f(-3) = -7.

This makes your answer B, -7.

5/√2+9/√8-2√50+√32 rationalise the denominator and simplify

Alik [6]

Answer: $\displaystyle\ \Large \boldsymbol{ -\frac{5\cdot \sqrt{2} }{4}}$

Step-by-step explanation: $\displaystyle\ \Large \boldsymbol{} \frac{5}{\!\!\sqrt{2} } +\frac{9}{\!\!\sqrt{8} } -2\sqrt{50} +\sqrt{32} =\frac{1}{\!\!\sqrt{2} } \bigg(5+\frac{9}{\sqrt{4} } \bigg)+\sqrt{2} (\sqrt{16} -2\sqrt{25} ) \\\\\\\\\frac{1}{\sqrt{2} } (5+4,5)+\sqrt{2} (4-10)=\frac{9,5}{\sqrt{2} } -6\sqrt{2} =\frac{9,5-12}{\sqrt{2} } = \\\\\\-\frac{5\cdot \sqrt{2} }{4}$
