Which of the following descriptions represents the transformation shown in the image

Viktor [21]

Answer: A. 270° rotation, 3 units left, and 2 units up

Step-by-step explanation:

C = (1, 1) D = (3, 3) E = (2, -2)

270° rotation counterclockwise means (x, y) = (y, -x)

new C = (1, -1) new D = (3, -3) new E = (-2, -2)

3 units left means subtract 3 from the x-coordinate

newer C =( -2, -1) newer D = (0, -3) newer E = (-5, -2)

2 units up means add 2 to the y-coordinate

C' = (-2, 1) D' = (0, -1) E' = (-5, 0)

Since the first option worked, there is no need to check the other options.

Which line is a graph of the equation: 2x + 5y = -10?

Lady bird [3.3K]

Answer:

Step-by-step explanation:

2x + 5y = - 10 Subtract 2x from both sides

5y = -2x - 10 Divide by 5

y = -2x/5 - 10/5

y = 0.4x - 2

The slope is minus so the line is going from lower right to upper left as B and D are doing.

The y intercept is - 2. B goes through + 2 so it is not the answer.

The answer is D

Find the value of x help

Temka [501]

Answer:

6.7

Step-by-step explanation:

This is trigonometry. We will have to find the opposite leg and the hypotenuse is given to us as 10. So we will have to use sin.

Soh in Soh cah toa

So sin(42)=x/10

10 times sin(42)=x

Evaluate using a calculator=6.69130606 and so on

Rounded to the nearest tenth is 6.7

So the answer is 6.7

Solve using the quadratic formula: 2x2-9x+12=0

marta [7]

Answer:

no solution

Step-by-step explanation:

For getting the nature of solution of the quadratic equation of the form:

ax² + bx + c = 0

We need to find Discriminant which is:

Discriminant (D) = b² - 4ac

If D < 0, there is no solution of equation.
If D = 0, there are two equal and real solution of equation
If D < 0, there are two real and distinct solution of equation

Here we have equation is:

2x² - 9x + 12 = 0

∴ a=2, b = -9, c = 12

⇒ D = 81 - 4 × 2 × 12 = -16 < 0

Hence, there is no solution of given equation.
