Hi there!

$\large\boxed{\frac{1}{4}, -\frac{3}{2}}$

13y² + 10y - 3 = 5y²

Begin by moving all terms to one side:

13y² + 10y - 3 - 5y² = 0

Combine like terms:

8y² + 10y - 3 = 0

Factor using the guess-and-check method.

(4y - 1)(2y + 3) = 0

Set each factor equal to 0 to find the solutions:

4y - 1 = 0

4y = 1

y = 1/4

2y + 3 = 0

2y = -3

y = -3/2

3/4h*19mi/1/4h. Can you please help me I need an answer by tonight

aniked [119]

Answer:

$57mi$

Step-by-step explanation:

we have

$\frac{3}{4}h*19mi/\frac{1}{4}h$

we know that

$\frac{3}{4}h*19mi/\frac{1}{4}h=\frac{(3/4)h}{(1/4)h}*19mi\\ \\=3*19mi\\ \\=57mi$

2, 8, 9, 20, 22, 25, 5<br> Mean ??<br> Mode ??<br> Median ??

Kobotan [32]

Answer:

the mean is the sum of them all divided by the number of terms.

mean: 13

the mode is the element that occurs MOST in the data set.

mode: none

the median is the middle value of all of the numbers.

median: 9

Which ordered pair is a solution to the system of inequalities ? (1, –5) (3, 0) (–1, –2) (1, 5)

Musya8 [376]

Point (3,0) is system solution.

<h3>What is inequality?</h3>

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

We have

y> -2

x + y <4

For (1,-5):

First inequation:

-5> -2 (incorrect)

Second inequality:

1-5 <4 (correct)

For (3,0):

First inequation:

0> -2 (correct)

Second inequality:

0+3 <4 (correct)

For (-1,-2):

First inequation:

-2> -2 (incorrect)

Second inequality:

-1-2 <4 (correct)

For (1,5):

First inequation:

5> -2 (correct)

Second inequality:

1+5 <4 (incorrect)

Hence, Point (3,0) is system solution.

Show how you can determine that the inscribed figure inside a quadrilateral is a parallelogram. Support your argument with diagr

denis23 [38]

Answer:

Look for perpendicular lines or corresponding angles or alternate interior angles.

Step-by-step explanation:

When you want to show that a quadrilateral is a parallelogram you need to show that the oposite sides are parallel. In order to show that two segments are parallel there are various theorems and definitions you can use.

1 - Remember that two lines perpendicular to the same segment are parallel.

2 - When two lines are cut by a secant and their alternate interior angles are congruent, then the resulting lines are parallel, I will attach a drawing to illustrate what I am saying.

3 - When two lines are cut by a secant and their CORRESPONDING angles are congruent, then the resulting lines are parallel, I will also attach a drawing to illustrate what I am saying.
