-6 is a solution for -4x > 16

Answers

Answer:

True

Step-by-step explanation:

-4x > 16

Divide each side by -4, remembering to flip the inequality since we are dividing by a negative

-4x/-4 < 16/-4

x < -4

-6 is less than -4 so -6 is a solution to the inequality

Given a triangle JLM with vertices J(-4,3), L(-2,7), and M(2,7). What would the coordinates be if it was reflected across the line y=1?

Answers

Answer: M'(2, - 5), L'(-2, -5), j'(-4, - 1)

Step-by-step explanation:

When we do a reflection over a given line, the distance between all the points (measured perpendicularly to the line) does not change.

The line is y = 1.

Notice that a reflection over a line y = a (for any real value a) only changes the value of the variable y.

Let's reflect the points:

J(-4, 3)

The distance between 3 and 1 is:

D = 3 - 1 = 2.

Then the new value of y must also be at a distance 2 of the line y = 1

1 - 2 = 1

The new point is:

j'(-4, - 1)

L(-2, 7)

The distance between 7 and 1 is:

7 - 1 = 6.

The new value of y will be:

1 - 6 = -5

The new point is:

L'(-2, -5)

M(2,7)

Same as above, the new point will be:

M'(2, - 5)

What is the value of x?
93

72

Answers

Answer:

72°

Explanation:

Given that line J and line K are parallel, we can safely assume that line m is the transversal for the following question. We can also remove line l so that we can focus on line m instead.

Using the rule of Alternate Exterior Angle theorem, x would equal to 72°.

Answer: 72

Now that we are told that J and K are parallel, we know that there can be a transversal line (m). You can see that m goes 72 degrees.

So, the answer is 72. Best of Regards!

con someone hwlp me please i can give you a brainle​

Answers

Answer:

For the first section, you write the algebraic expression or equation that goes with the statement.

For example, 9 more than the product of 51 and number "i" would translate into 51i+9. More and sum refers to addition, difference is subtraction, and quotient is division.

For the second section, you just simplify each of the expressions. when a number has ^, that means it has the square root, so 9^2 would be nine squared, which is 81.

For the third section, replace the c values for 3 and the d values for 5.

For the fourth section, determine whether or not each number is rational by writing the number as a fraction where both numerator and denominator are whole numbers. Pi is irrational as it can't be written as the fraction of 2 integers

For the last section, combine like terms and explain each step.
