6cm , 12cm

Step-by-step explanation:

Answer:

8ab

Step-by-step explanation:

Answer:

since,

y = 2x and y = –2x + 15

then,

2x = –2x + 15

or, 4x = 15

or, x = 15/4

or, x = 3.75

Also,

y= 2x

= 2*3.75

= 7.5

Hope it helped

All the best!!

Answer:

Step-by-step explanation:

[tex]x^{2} = -2x^{2} +15[/tex]

add [tex]2x^{2}[/tex] to both sides

[tex]3x^{2} = 15[/tex]

divide each side by 3

[tex]x^{2} =5[/tex]

square root each side [tex]\sqrt{x^2} =\sqrt{5}[/tex]

[tex]x= 2.23606794[/tex] or rounded to the nearest hundredth [tex]x=2.24[/tex] or x = ±[tex]\sqrt{5}[/tex]

Answer:

Step-by-step explanation:

6x-12y

trust me

Answer:

9x-7y-3x-5y

= 6x-12y

Step-by-step explanation:

9x and -3x are like terms as they both are "x" values

-7y and -5y are like terms as they both are "y" values

To receive the x value you subtract 3x from 9x giving you 6x

To receive the y value you subtract -5y from -7y giving you -12y

Hope that helps (:

Answer:

16.8

Step-by-step explanation:

just look at the length to the side of it (the "28") and look at the given answers. 4 seems way too small and because the line is shorter than 28 it cant be 43, so 16.8 is the most reasonable option.

Answer:

Initial population is 2,466,000 ( p0 )

Growth is 1.1% each year ( r=1.1

p(t)=p0(1+r)t

After 30 years, the population of Jamaica should be 3.42 million by that calculation, but it is only 2.95 million, so apparently that growth rate was a little high, or wasn’t sustained.

Answer:

x = 9

Step-by-step explanation:

Given

(x + [tex]\frac{2}{3}[/tex] x ) - [tex]\frac{1}{3}[/tex](x + [tex]\frac{2}{3}[/tex] x ) = 10 ← distribute parenthesis

x + [tex]\frac{2}{3}[/tex] x - [tex]\frac{1}{3}[/tex] x - [tex]\frac{2}{9}[/tex] x = 10

Multiply through by 9 ( the LCM of 3 and 9 ) to clear the fractions

9x + 6x - 3x - 2x = 90

10x = 90 ( divide both sides by 10 )

x = 9

Answer:

There are 380 students and 20 teachers.

Answer:

380

Step-by-step explanation:

Let 19x =  no. of students

        x =  no. of teachers

Then,  x + 19x = 400

20x = 400

x = 20

19x = 19(20) = 380

Answer:

(p - 4)(p + 4)

Step-by-step explanation:

p² - 16 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

p² - 16

= p² - 4²

= (p - 4)(p + 4)

Answer:

A

Step-by-step explanation:

Find AB using the Law of Sine:

[tex] \frac{AB}{sin(C)} = \frac{AC}{sin(B)} [/tex]

Thus:

[tex] \frac{AB}{sin(40)} = \frac{47}{sin(103)} [/tex]

Multiply both sides by sin(40)

[tex] \frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40) [/tex]

[tex] AB = \frac{47*Sin(40)}{sin(103)} [/tex]

AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

Hey there!

First, we are given:

[tex]\frac{1\frac{1}{4}}{1\frac{3}{8}}[/tex]

To make this easier, I am going to change the fractions in to decimals.

[tex]\frac{1.25}{0.375}[/tex]

To get the unit rate, we can use proportions:

[tex]\frac{1.25}{0.375} = \frac{x}{1}[/tex]

Using cross products, we know that...

[tex]1.25 * 1 = 0.375 * x[/tex]

Now, we solve for [tex]x[/tex]:

[tex]1.25 * 1 = 0.375 * x\\ 1.25 = 0.375x\\ 3 \frac{1}{3} = x[/tex]

Therefore, the unit rate is [tex]\frac{3\frac{1}{3} }{1}[/tex]

Now, do the same with the other problem, and the unit rate is [tex]\frac{1\frac{4}{5} }{1}[/tex]

Have a terrificly amazing day!!!

Answer:

x=5 and y=7

Step-by-step explanation:

The opposite parallel sides of any rhombus are going to be equal.

a.) Knowing this you take (x+14) and make it equal to (5x-2). Then you subtract the x from (x+14), and add the 2 from (5x+2), making the new equation 16=4x. You divide 4 by x and by 16, getting the final simplified answer of x=4.

b.) Using the same method you take 3y-3 and set it equal to (2y+4). Then you subtract the 2y from (2y+4) and add the 3 from (3y-3) to bother sides. Now you have your new equation and answer being y=7.

a.) x+14 = 5x-2

b.) 3y-3 = 2y+4

Answers:

Graph A is a function

Graph B is not a function

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

Explanation:

To check if we have function or not, we apply the vertical line test. This test is where you ask yourself: "Is it possible to draw a single vertical line through more than one point on the curve?"

If the answer to that question is "yes it is possible", then we do not have a function. Graph B shows that we can draw a line through say x = 2 and have the vertical line intersect at points (2,2) and (2,4). The input x = 2 leads to multiple outputs y = 2 and y = 4 simultaneously. This is why graph B is not a function.

A function is only possible when any x input from the domain leads to exactly one y output in the range. Graph A is a function because we cannot draw a single vertical line to intersect through that curve more than once.

Answer:

Start at the point (0,-2), and go down three points, to the coordinate (0,-5), then go right 2 points, to the coordinate (2,-5). Then draw a line from (2,-5), through (0,-2)

Step-by-step explanation:

Answer:

your second point will be (2,-5) x=2 y=-5. your first point will be (0,-2) x=0 y=-2.  connect them to make a line.

Step-by-step explanation:

So I’m doing this right now. Basically, you need to create a chart.

x and y. So if x=0, solve for y. You need at least 2 points like this to solve it.

I’ll choose 0.

y=-3/2x-2

y=0-2

y=-2

your first point will be (0,-2) x=0 y=-2.

I’ll choose 2.

y=-3/2x-2

y=-3/2*2-2

y=-3-2

y=-5

your second point will be (2,-5) x=2 y=-5.

Answer:

a=6

Step-by-step explanation:

We are given that an equation

[tex]14a=84[/tex]

We have to solve the equation

To solve the equation we will use division property of equality

By using division property of equality

We get

[tex]a=\frac{84}{14}[/tex]

[tex]a=\frac{14\times 6}{14}[/tex]

[tex]a=6[/tex]

Hence, a=6
