- 7 ( x - 2 ) + 1 = 15 - 7x

Mathematics

Savatey [412]3 years ago
5 0

Answer: x=1

Step-by-step explanation:

You need to open up the parenthesis so you multiply every term inside the parenthesis by -7.

1.  -7x + 14 + 1 = 15 -7x

2. Combine like terms -7x + 15 = 15-7x

The two sides of the equation are the same so that means that x=1

What are the solution(s) to the quadratic equation 40 - x2 = 0?
Julli [10]

Answer:

x = ±2√10

Step-by-step explanation:

40 - x² = 0

⇌  

(√40 - x)(√40 + x) = 0  

⇌

x = √40  or  x = -√40

we can go further and say that √40 = 2√10

viktelen [127]

Answer:

log_{b} (5b) = 2.609

Given that:

log_{b} (3) = 1.099

log_{b} (5) = 1.609

Evaluating with that:

\sf log_b (5b) = log_b\left(5\right)+log_b\left(b\right)

            = \sf 1.609 + 1

             = \sf 2.609

Rule Used:

\rm \log _a\left(xy\right)=\log _a\left(x\right)+\log _a\left(y\right)
