Which phrase represents this expression? 42−3×8

Mathematics
1 answer:
iVinArrow [24]2 years ago
3 0

Answer: C

Step-by-step explanation:

Let’s establish some key terms here:

Subtraction = <u>Difference</u>

Multiplication = <u>Product</u>

Division = <u>Quotient</u>

Addition = <u>Sum</u>

First, we know that there is subtraction and multiplication is the problem, so we will be using the words difference and product.

The only answer that uses both these words is answer C.

Either way, let’s check it.

Answer C is “the difference of 42 and the product of 3 and 8”. Let’s break it down.

We see the word “product“ here, talking about the 3 and the 8. In the original equation, the 3 and 8 were multiplied, so this does make sense.

We also see the word “difference”, talking about the 42 and the product (of 3 and 8). These were subtracted by each other in the original equation, so it makes sense.

Therefore, the answer is C: the difference of 42 and the product of 3 and 8.

Hope this helps! :)

Which transformations could have been used to create A'B'C'? Choose all that apply.
Eduardwww [97]

The correct transformation is a rotation of 180° around the origin followed by a translation of 3 units up and 1 unit to the left.

<h3>Which transformation is used to get A'B'C'?</h3>

To analyze this we can only follow one of the vertices of the triangle.

Let's follow A.

A starts at (3, 4). If we apply a rotation of 180° about the origin, we end up in the third quadrant in the coordinates:

(-3, -4)

Now if you look at A', you can see that the coordinates are:

A' = (-4, -1)

To go from (-3, -4) to (-4, -1), we move one unit to the left and 3 units up.

Then the complete transformation is:

A rotation of 180° around the origin, followed by a translation of 3 units up and 1 unit to the left.

Use the quadratic formula to solve for the roots of the following equation.<br> x 2 – 4x + 13 = 0
Artyom0805 [142]
  • Quadratic Formula: x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} , with a = x^2 coefficient, b = x coefficient, and c = constant

With our equation, plug in the values:

x=\frac{4\pm \sqrt{(-4)^2-4*1*13}}{2*1}

Next, solve the exponent and multiplications:

x=\frac{4\pm \sqrt{16-52}}{2}

Next, solve the subtraction:

x=\frac{4\pm \sqrt{-36}}{2}

Next, factor out i (i = √-1):

x=\frac{4\pm \sqrt{36}i}{2}

Next, solve the square root:

x=\frac{4\pm 6i}{2}

Lastly, divide and <u>your answer is:</u>

x=2\pm 3i
