Match the ordered pairs so that the relation defined by the set of ordered pairs does not represent a function.

1 answer:

5 0

From what I understand about the problem, I think you have to match them so that the x values are the same. For two coordinate points to be on the same function, every x has to have its own y. Since we're trying to <em>not </em>make a function, we should deliberately match the x values.

(2,3) (2,2)
(-5,2) (-5,1)
(6,-5) (6,5)
(-1,0) (-1,6)

I'm not sure where the (0,3) belongs.

Please help! The answer is not A I got this question wrong.

Answer:

Right option is (D).

ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Step-by-step explanation:

We have given,

Two triangles ΔABC and ΔDBE such as :

$\frac{BD}{BA} =\frac{BE}{BC}$

This relation will contribute to side side similarity.

Also,

∠B = ∠B , This will contribute as an angle similarity .

So combining above two relations,

$\frac{BD}{BA} =\frac{BE}{BC}$

and ∠B = ∠B

we can conclude that the triangle ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Hence the right option is (C)

What quadratic inequality does the graph below represent?

barxatty [35]

The quadratic graph crosses the y-axis at -3, so the equation is $y= x^{2} -3$

The shaded region is on 'outer' part of the graph, hence the inequality is

$y\ \textgreater \ x^{2} -3$

Given ABC find the values of x and y. In your final answer, include all of your calculations.

So with this, we will be using proportions. To solve for x, our proportion will be $\frac{x}{6} =\frac{6}{x-9}$

Firstly, cross-multiply: $x^2-9x=36$

Next, subtract 36 on both sides: $x^2-9x-36=0$

Next, replace -9x with 3x-12x $x^2+3x-12x-36=0$

Next, factor x^2+3x and -12x-36 separately: $x(x+3)-12(x+3)=0$ . After, rewrite it as $(x-12)(x+3)=0$

Next, solve for x separately in the two parentheses:

$x-12=0\\ x=12$

$x+3=0\\ x=-3$

Since we can't have a negative length, x = 12.

To solve for y, our proportion will be $\frac{y}{9} =\frac{12}{y}$

Firstly, cross-multiply: $y^2=108$

Next, just square root each side, and your answer will be (rounded to hundredths) $y=10.39$

In short, x = 12 and y = 10.39.

Answers:

Angle A = 62.1 degrees

Angle X corresponds to angle A

The triangles are not similar

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

Explanation:

To find angle A, subtract the given angles B and C from 180 to get 180 - B - C = 180 - 60.8 - 57.1 = 62.1 degrees

Notice how none of the angles of triangle ABC have a measure of 59.1, so this means that angle Y cannot be congruent to any of A, B or C. This is why the triangles are not similar. We would need 2 pairs of congruent angles to use the AA (angle angle) similarity theorem.

If the triangles were similar, then we can say triangle ABC is similar to triangle XYZ. The letters A and X are the first letters mentioned of the trio of letters, which means that they correspond to one another.
