O2 + 3x + 5
O x-1 +X-2 + x
0-3 - 3x – 1 + x
03 – 3x

Answer:

3 pens.

Step-by-step explanation:

x+y=7 where x is # of pens and y =# of pencils

3x + 2y= $18

from first equation, x=-y+7 so substitute that into other equation

3(-y+7)+2y=18

-3y+21+2y=18

-y=18-21

-y=-3

y=3

now replace y =3 into first equation

x+3=7

x=4

Hello! answer: 8.0 m

Step-by-step explanation:

8 × 8 = 64

15 × 15 = 225

64 + 225 = 289

√289 = 17

therefore 8 would be the missing angle

Answer:

9 pi

Step-by-step explanation:

First find the circumference of the circle

C =2 * pi *r

C = 2 * pi *9

C = 18 pi

This is a semicircle which is 1/2 of a circle

Take 1/2 of the circumference

1/2 C = 1/2 ( 18 pi)

1/2 C = 9 pi

2x² + 9x - 5 = 0

b = 9

Step-by-step explanation:

(2x - 1) (x + 5) = 0

Expand

2x² + 10x - x - 5 = 0

Simplify

2x² + 9x - 5 = 0

b = 9

Step-by-step explanation:

in a parallelogram, opposite angles are equal..

so C is 4a + 22. and B is 6a - 12.

sum of interior angles in a quadrilateral = 360

4a + 22. + 6a - 12. + 4a + 22. + 6a - 12 = 360

20a + 20 = 360

20a = 340

a = 17

sum of angles on a straight line = 180

B + x = 180

6 ( 17) - 12 + x = 180

102 + × = 180

× = 180 - 102

× = 78

We know that:

Factorize the expression for the area and find the missing side

Given:

Find l:

l = A/w

l = (x² + 10x + 21)/(x + 3) =

    (x + 3)(x + 7)/(x + 3 =

    x + 7

------------------------------

Given:

Find w:

w = A/l

w = (x² + 2x - 8)/(x + 4) =

      (x + 4)(x - 2)/(x + 4) =

      x - 2

Answer and Step-by-step explanation:

We are given a linear pair. The angles of a linear pair add up to 180.

To find x, add the two angles together and equal it to 180, then solve for x.

126 + x + 23 = 180

Simplify.

149 + x = 180

Subtract both sides of the equation by 149.

x = 31

x = 31 is the answer.

Answer:

not whoever wrote this question. every 10th person is surveyed. she surveyed 50 people. that mean 500 people and 50 surveyed people. then at the end the teacher said there is 1000 students. your teacher wrote you a bad question with no right answers.

The answers to all limits are:

(a) lim x → a [ f(x) + 2g(x)] =  -6,

(b) lim x → a [h(x) − 3g(x) + 1] = 13

(c) lim x → a [ f(x)g(x)] = -8

(d) lim x → a [g (x)]² = 16

(e) lim x → a 3√6 + f(x) / 2g(x)

The central limit theorem states that if you take sufficiently large samples from a population, the samples' means will be normally distributed, even if the population isn't normally distributed.

here, we have,

(a) lim x → a [ f(x) + 2g(x)]

= lim x → a f(x) + 2 lim x → a g(x) (using algebraic limit theorem)

= 2 + 2(-4)

= -6

(b) lim x → a [h(x) − 3g(x) + 1]

= lim x → a h(x) - 3 lim x → a g(x) + lim x → a 1 (using algebraic limit theorem)

= 0 - 3(-4) + 1

= 13

(c) lim x → a [ f(x)g(x)]

= lim x → a f(x) * lim x → a g(x) (using algebraic limit theorem)

= 2 * (-4)

= -8

(d) lim x → a [g(x)]²

= [lim x → a g(x)]^2 (using algebraic limit theorem)

= (-4)^2

= 16

(e) lim x → a 3√6 + f(x) / 2g(x)

= [3√6 + lim x → a f(x)] / [2 lim x → a g(x)] (using algebraic limit theorem)

= [3√6 + 2] / [2(-4)]

= (-3√6 - 2) / 8

Therefore, the answers to all limits are:

(a) lim x → a [ f(x) + 2g(x)] =  -6,

(b) lim x → a [h(x) − 3g(x) + 1] = 13

(c) lim x → a [ f(x)g(x)] = -8

(d) lim x → a [g (x)]² = 16

(e) lim x → a 3√6 + f(x) / 2g(x)

[tex]54000 \times 1200 = 64800000 = 6.48 \times 10^{7}[/tex]

The result of 54,000 × 1,200 in scientific notation is written as [tex]6.48[/tex] ×[tex]10^{7}[/tex].

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

According to the question

We have , 54,000×1,200

Therefore,

The the result 54,000× 1,200 in scientific notation is given by

54,000 × 1,200

= 64,800,000

= [tex]648[/tex] × [tex]10^{5}[/tex]

= [tex]6.48[/tex] × [tex]10^{7}[/tex]

Hence, the result of 54,000×1,200 in scientific notation is written as [tex]6.48[/tex]×[tex]10^{7}[/tex].

Answer:

y - 6 = 9(x + 3)

Step-by-step explanation:

The point slope equation of a line is: y - y1 = m(x- x1), where m is the slope and (x1, y1) is a point on the line.

First, plug in the slope:

y - y1 = 9(x- x1)

Now, plug in the given point:

y - 6 = 9(x + 3)

So, the equation in point slope form is y - 6 = 9(x + 3)

The axis of symmetry is what straight line would divide the parabola directly in half.

Answer:

A. -1.5 B.2

Step-by-step explanation:

The Axis of symmetry is the line that goes through the center of the parabola. And resembles a symmetrical shape that makes the parabola look the same on both sides.

In this case for A, -1.5 would be the answer because it is in the center of the parabola on the x-axis. For B, 2 is the axis of symmetry because it lines up in the center of the parabola.

The item can be anything really. I'm going to add a trampoline which is a square shown in purple. The square is rotated 45 degrees so it looks like a diamond shape. The rotation isn't necessary but I figured to spice things up compared to the other figures which were mostly squares or rectangles. If we split the purple square into 4 triangles, and apply the pythagorean theorem, then we can find the length of each side of the purple square to be roughly 2.828 cm.

Scaling things up, the trampoline in real life is 2*2.828 = 5.656 meters along each dimension.

With any square the angles are always 90 degrees.

Answer:

13 units

Step-by-step explanation:

(6 , 5) = (x2 , y2)

distance = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

=[tex]\sqrt{{6 - (-7)}^2 + (5 - 5)^2}[/tex]

=[tex]\sqrt{(6 + 7)^2 + (0)^2}[/tex]

=[tex]\sqrt{(13)^2 + 0}[/tex]

=[tex]\sqrt{169}[/tex]

Answer:

Plug in the given points (-7,5) and (6,5)

[tex]d=\sqrt{(6-(-7))^2+(5-5)^2}\\d=\sqrt{(6+7)^2+(5-5)^2}\\d=\sqrt{(13)^2+(0)^2}\\d=\sqrt{(13)^2}\\d=13[/tex]
