Answer: B) Infinitely many solutions; both equations are equivalent

==============================================================

Work Shown:

x+y = 4 ... start with the first equation

x + (-x+4) = 4 ... replace y with (-x+4)

x-x+4 = 4

0x+4 = 4

0+4 = 4

4 = 4 ... this is a true statement regardless of what x you pick

So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.

Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.

The figure shows three quadrilaterals on a coordinate grid: see image

FrozenT [24]

Hello!

The statement that is true about the three quadrilaterals is the first one:

$\boxed{ \bf D~and~E~are~similar~but~not~congruent.}$

____________________________________________________________

Option #2 is incorrect because although E and F are similar, they are not congruent. They do not have the same size.

Option #3 is also incorrect because, again, D and E are similar, but they are not congruent.

Option #4 is not correct because it says that "F and D are similar but not congruent." This is not true since they are the same shape and size. Only their orientation is different, which makes them congruent.

Identify the graph that correctly represents the inequality |x + 1| + 2 > 5.

NeTakaya

$|x+1|\ \textgreater \ 3$

The greater than 3 means that the graph will have a shaded region for when the absolute value of (x+1) is greater than 3.

The absolute value means that we are interested in the magnitude of x+1. That means that the the graph will be shaded where x+1 > 3, and where -x-1 > 3

If we solve both of these for x, we get:

x > 2 and x < -4

So the graph will look like the attached picture. Notice that the vertical lines are dotted rather than solid. This means that we are dealing with a greater than sign, not a greater than or equal to.

A test has 20 true/false questions. What is the probability that a student passes the test if they guess the answers? Passing me

Minchanka [31]

Using the binomial distribution, it is found that:

The probability that the student will get 15 correct questions in this test by guessing is 0.0207 = 2.07%.

For each question, there are only two possible outcomes, either the guess is correct, or it is not. The guess on a question is independent of any other question, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
