9. What is the correct factorization of
x2 + 13x + 30?

Answer:

x=1 y=14

multiply x-y=-13 by 3 so the x would cancel out. solve for y

then plug in y to one of the equations to get x

Answer: the answer is x= -2 , y=11

Step-by-step explanation:

First

1: we have to find the answer for x in x-y= -13

2: add y on both sides of the equation

3: we will get x= -13+y

Second

1: Substitute x in 3x-y= -17 with x=-13+y

2: then you will get 3(-13+y)-y= -17

3: multiply 3 with -13 and y

4: you will get -39+3y-y =-17

5: add 3y and -y

6: you will get -39+2y= -17

7: add 39 on both sides of the equation

8: you will get 2y=22

9: divide 2 on both sides

10: you will get y= 11

Third

1: plug 11 for y in x= -13+y

2:  then you will get x= -13+11

3:  you will x= -2

So x= -2 and y= 11

Actually Welcome to the concept of Locus of a shape.

Here, the left movement is in x direction and vertical or up movement is in the y direction.

so we get as,

A(1,-2) ==> 1 towards left => 0

and 3 units up => 1

hence the new co-ordinates are A(0,1)

hence, A(0,1) is correct option

Answer:

$3240

Step-by-step explanation:

First you need to find the area of that lot. Area of a rectangle = length x width. But you also have mixed units...yards and feet. Since the price of the sod is in square yards, we'll convert the 45 feet to yards. 3 feet = 1 yard, so divide 45 by 3, = 15 yards.

18 x 15 = 270 square yards

then you multiply that by the $12/square yard

270 x 12 = $3,240

Please lmk if you have questions

Answer:

The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.

Answer:

[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]

Step-by-step explanation:

Since the hyperbola opens left and right with a center at the origin, then

[tex]\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1[/tex]

In the graph a = 60 and b = 11

So

[tex]\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1[/tex].

[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]

whats this homework called and ill help u

Step-by-step explanation:

Answer:

y= 3x +2

Step-by-step explanation:

-10x-30y = 6

-30y = 10x +6

y = -1/3x - 1/5

m = -1/3 perpendicular slope would be 3

2x+9y = 18

2(0) +9y = 18

y = 2 = y intercept

y = 3x +2

MARK ME AS BRAINLIST

Answer:

20.78 feets

Step-by-step explanation:

Based on the solution diagram attached below :

The height at which the step ladder meets the house can be obtained thus :

Using trigonometry :

Sin θ = opposite / hypotenus

Sin θ = h / 24

Sin 60 = h / 24

0.8660254 = h/24

Height, h = 0.8660254 * 24

Height, h = 20.78 feets

Answer:

38 degrees

Step-by-step explanation:

this is an isosceles triangle, meaning that the base angles are congruent.

the total triangle is equal to 180

so the equation would be: x=180 - (71+71)

evaluate:

x=180-142

x=38 degrees
