Answer:

6

Step-by-step explanation:

Plug the values of a and b into the equation.

4(3) + 5(-1.2)

12 + (-6)

Adding negatives basically means subtracting, so...

12-6 = 6

Therefore your answer is 6

Hope this helps!

Answer:

  • A'(-3, 12)
  • B'(9, 6)
  • C'(-6, -6)

Step-by-step explanation:

Dilation about the origin multiplies each coordinate value by the dilation factor.

For dilation factor k, the new coordinates are ...

  (x, y) ⇒ (kx, ky)

Your dilation factor is 3, so the transformation is ...

  (x, y) ⇒ (3x, 3y)

  A(-1, 4) ⇒ A'(-3, 12)

  B(3, 2) ⇒ B'(9, 6)

  C(-2, -2) ⇒ C'(-6, -6)

Solve the following exponential equation:<br><br>5^x=2 <br><br>e^x=10​
olya-2409 [2.1K]

Number 1.

5^x=2, first we will take the log of both of these numbers getting us,

x=\frac{log(2)}{log(5)}, which then gives us that x=0.4306777777....

Number 2

e^x=10, solve for our exponent, 2.718282^x=10, use the logarithmic formula, and we get,

x=\frac{log(10)}{log(2.718282)}, which then we get that x=2.302585
