Answer:

x=-8 then x times y coulum = x coulum answer same for if y=-9 then times x coulum =y coulum answers if y=x+5 solve for x be making y=0

Step-by-step explanation:

Start by piking the equations you want to use and put them on the lines below the box the take and put that into a table with that if it’s a x then you start with the y coulum and put -2,-1,0,1,2 ok then from their if you know what x is you times it by the y coulum and contiue to do that with all the x integers this is the same for the y integers except it’s switched. If you still don’t understand I suggest asking your teacher for help and be honest with them that you didn’t understand it.

The ratio of the measures of the angles in a

Gwar [14]

Explanation:-

We have given measure of angles of the triangle are in ratio 4 : 7 : 9 and here we need to find the measure of largest angle of a ∆.

Let, the three angles of a triangle be 4x, 7x, 9x.

We know that, Sum of all angles of a triangle is 180°.

4x + 7x + 9x = 180°

⇛20x = 180°

⇛x = 180°:20

⇛x = 9°

Now, finding largest angle by putting the value of “x”

4x = 4(9) = 36°
7x = 7(9) = 63°
9x = 9(9) = 81°

Hence ,the measure of largest angle is 81°.

HELP ASAP! Use the quadratic equation y = –2x^2 + 4x +5 to complete the statements.

gregori [183]

Answer:

Step-by-step explanation:

Given quadratic equation is,

y = -2x² + 4x + 5

y = -2(x² - 2x) + 5

y = -2(x² - 2x + 1 - 1) + 5

y = -2(x² - 2x + 1) + 2 + 5

y = -2(x - 1)² + 7

This equation is in the vertex form of the quadratic equation,

y = a(x - h)² + k

where, (h, k) is the vertex of the parabola.

Therefore, vertex of the given quadratic equation is (1, 7)

The equation can be rewritten as y = -2(x - 1)² + 7.

Therefore, the vertex of the graph of the function y = -2x² + 4x + 5 in the xy-coordinate plane is located at the point (1, 7).

Marissa notices that the top of the net is 20 inches higher than the tallest player on the team. The net is less than 90 inches

Vika [28.1K]

No, the inequality uses less than or equal to, but it should be less than. The relationship could be written as h + 20 < 90. This says that the tallest player’s height plus 20 inches is less than 90 inches.

Tobias rented a kayak from a sports equipment store.

Ket [755]

Answer:

Step-by-step explanation:

Let x = every day he rented the kayak

Since the store charges $60 for each day, multiply x by 60 like this: 60x

They also have $25 on top of that; 60x + 25

This all has to equal $325; 60x + 25 = 325

To solve for x, subtract 25 from both sides

60x + 25 = 325

- 25 - 25

60x = 300

Divide both sides by 60

60x/60 = 300/60

x = 5

This means Tobias rented the kayak for 5 days
