<u>Answer:</u>

The correct answer option is a) there are an infinite number of solutions

<u>Step-by-step explanation:</u>

We are given these two following equations:

15x = 5y - 5 --- (1)

y = 3x + 1 --- (2)

Solving these two by the substitution method by putting the value of y in equation (1).

15x = 5y - 5

15x = 5(3x + 1) - 1

15x = 15x + 5 - 5

5 and -5 get cancelled and we are left with 15 on both sides of the equation which will cancel each other.

Therefore, these equations have an infinite number of solutions.

A car initially traveling at 20 kilometers per hour takes 10 seconds to speed up to 70 km/hour. At what rate is it changing spee
Snezhnost [94]
  • Initial velocity=u=20km/h
  • Final velocity=v=70km/h
  • Time=10s=t

Convert speeds to m/s

\\ \rm\longmapsto u=20\times\dfrac{5}{18}=5.05m/s

\\ \rm\longmapsto v=70\times \dfrac{5}{18}=19.4m/s

\boxed{\sf Acceleration=\dfrac{v-u}{t}}

\\ \rm\longmapsto Acceleration=\dfrac{19.4-5.05}{10}

\\ \rm\longmapsto Acceleration=\dfrac{14.3}{10}

\\ \rm\longmapsto Acceleration=143m/s^2

Y’all pls help me :(
Ilia_Sergeevich [38]

Answer: B

Step-by-step explanation:

When you are multiplying exponents, if the base is the same, then you can directly add the exponents together.

We can see that both bases are 6. That means we can add the exponents.

3+\frac{1}{4}                             [common denominator]

\frac{12}{4}+\frac{1}{4}                            [add]

\frac{13}{4}

Now, we know that the answer will be 6^1^3^/^4.
