Answer: 30 months

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

Matthew's saving account money (1500) must be equal to the product of the amount he pays per month for the app subscription  (20) and the number of months (x); plus the product of the amount he pays per month for the Italian restaurant subscription  (30) and the number of months (x).

1500= 20x+30x

Solving for x:

1500=50x

1500/50 =x

30 months =x

Answer:

4x^2 -12x +9   ft^2

Step-by-step explanation:

The area of a square is

A = s^2 where s is the side length

A = (2x-3) ^2

A = (2x-3) (2x-3)

FOIL

first 2x*2x =4x^2

outer 2x (-3) = -6x

inner -3*2x = -6x

last -3*-3 = 9

Add them together

4x^2 -6x-6x +9

Combine like terms

4x^2 -12x +9

The area is 4x^2 -12x +9 ft^2

Answer:

[tex]= 4 {x}^{2} - 12x + 9 {ft}^{2} \\ [/tex]

Step-by-step explanation:

[tex]area = {x}^{2} \\ = (2x - 3)^{2} \\ = (2x - 3)(2x - 3) \\ = 2x(2x - 3) - 3(2x - 3) \\ = 4 {x}^{2} - 6x - 6x + 9 \\ = 4 {x}^{2} - 12x + 9 {ft}^{2} [/tex]

Step-by-step explanation:

Answer:

Equation for the function is:

f(x) = (3/2) · 2ˣ

Step-by-step explanation:

We have been provided with 2 points

Point 1 : (3, 12)

Point 2 : (4, 24)

Testing all three equations:

Substitute x of Point 1 in the equation

f(x) = (6/3) · 2³

f(x) = 16

y = 16 ≠ 12

NOT TRUE

Substitute x of Point 2 in the equation:

f(x) = (6/3) · 2⁴

f(x) = 32 ≠ 24

NOT TRUE

Substitute x of Point 1 in the equation

f(x) = (3/2) · 2³

f(x) = 12

y = 12

TRUE

Substitute x of Point 2 in the equation:

f(x) = (3/2)· 2⁴

f(x) =  24

TRUE

Substitute x of Point 1 in the equation

f(x) = 2(3)

f(x) = 6

y = 6 ≠ 12

NOT TRUE

Substitute x of Point 2 in the equation:

f(x) = 2(4)

f(x) = 8 ≠ 24

NOT TRUE

Answer:

x = 3

Step-by-step explanation:

The area of a rectangle is length*width, while for a rectangle it is the length*width over two. Now lets substitute the values given.

3(x+12) = 3x+36 = Area of rectangle

5(2x)/2 = 10x/2 = 5x = Area of triangle

We know that the area of the rectangle is 3 times the area of the triangle, so 3x + 36 = 3(5x) --> 3x+36 = 15x

This gives basic linear equation of 3x + 36 = 15x to solve. Isolate x and solve:

36 = 12x

x = 3

Answer:

∠NXO = 90° because the diagonals of a rhombus are perpendicular. Because the sum of angles in a triangle is 180°, 90 + 29 + ∠7 = 180 which means ∠7 = 61°.

Answer:

1329.8 cm³

Step-by-step explanation:

Volume of a Cylinder is: [tex]V=\pi r^2h[/tex]

We are given the height of 14 cm, and the diameter of 11 cm.

The radius is half the diameter.

[tex]11/2=5.5[/tex]

The radius is 5.5.

I use 3.14 for pi:

[tex]V=3.14*5.5^2*14\\\rightarrow 5.5^2=30.25\\V=3.14*30.25*14\\\boxed{V=1329.79}[/tex]

1329.79 ≈ 1329.8

The volume of the cylinder should be 1329.8 cm³.

Answer:

(y - 9)(y - 7) = [tex]y^2-16y+63[/tex]

(2y + 2)(y + 1) = [tex]2y^2+4y+2[/tex]

(2y + 6)(y + 3) =  [tex]2y^2+12y+18[/tex]

(3y + 4)(y + 5) = [tex]3y^2+19y+20[/tex]

Answer:

[tex]\huge \boxed{y^2 - 16y + 63}[/tex]

n > -9

Write an inequality to represent the model and solve for the unknown number

let

the unknown number = x

twice a number = 2 × x

= 2x

Three more than twice a number = 2x + 3

Three more than twice a number is greater than negative fifteen:

2x + 3 > -15

2x > -15 - 3

2x > - 18

Divide both sides by 2

x > -18/2

x > -9

Therefore, the unknown number x, is greater than -9

Answer:

f(q) = 11/3q+2/3

Step-by-step explanation:

11q - 4 = 3r - 6

Solve for r

Add 6 to each side

11q - 4+6 = 3r - 6+6

11q +2 = 3r

Divide each side by 3

11q/3 + 2/3 = 3r/3

11/3q + 2/3 = r

f(q) = 11/3q+2/3

Answer: A; 9/25

Step-by-step explanation:

First, you add up all the coloured t-shirts do you can find out the denominator. Then, you have the bottom number, 25. Now, you just find out the number of red t-shirts, which is 9.

So the probability of you picking a red t-shirt is 9/25

i wanna found all area firstly. thats why multiplaying 44 with 16.

44×16 = 704.

now ill find the triangle's area because ill remove it from the all area to find the shaded part of rectangle.

for triangle's area: 12×16/2 = 96.

now i substrack 704 from 96.

704-96= 608 square meters.

If the room dimensions are 8 1/3 feet by 11 1/2 feet, the perimeter length is ...

  P = 2(L+W) = 2(8 1/3 +11 1/2) = 2(19 5/6) = 39 2/3 feet

The area of the walls is the product of this perimeter length and the height of the wall. If that height is 12 feet, then the wall area is ...

The coordinates for point M is (12, 6)

Section formula is used to find the coordinates of a point that splits a line segment internally or externally into a ratio of m:n.

(x, y) = ( mx2 + nx1/ m+n, my2 + ny1/ m+n)

Given:

Coordinates of A(0, 15) and B (20, 0)

ratio is 3:2

Now,

x1=0, x2= 20, y1= 15, y2=0

let the coordinates of M is (c, d)

Using section formula

c=2*0+3*20/5

c=12

and d= 15*2+ 2*0/5

d= 6

Hence, the coordinates of M are (12, 6).
