Answer:

distance between (3,7) and (-6,-4) is [tex]\sqrt{202}[/tex]

Step-by-step explanation:

3rd point = (3, -4)

from (3,7) to (3, -4) is 11 units

from (-6,-4) to (3, -4) is 9 unites

hypothenuse

a^2 + b^2 = c^2

(11)^2 + (9)^2 = c^2

121 + 81 = c^2

c^2 = 202

c = [tex]\sqrt{202}[/tex]

Answer:  The equations aren't written properly.  They seem to be missing something, but if I interpret what is there, we have 1) V = x + 3, and 2) x = -2.

That can't be correct, but if it is, x = -2. and V = 1

Answer:

maybe A? B, D, E

Give brainlest if u agree :)

Step-by-step explanation:

A - Parrallelgrams do indeed have 1 pair of parrlell sides, but are not limited to 1. They in fact have 2 sides. If ur instructor is super literal i would put A, if not then technically a parallelogram has 2 pairs of parrallel sides.

B - True. opposite  pairs have the same measure of radians

C - Not true because of B

D - True, sides are same length

E - True, consecutive angles add to 180

Answer:  9) x = 2,  10) x = 3

Step-by-step explanation:

9)  (9x+7)+(-3x+20) = 39

9x + 7 -3x + 20 = 39

6x + 27 = 39

6x = 12

x = 2

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

10)  3x + 5x = 24

8x = 24

x = 3

Answer:

x = 9

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (9, - 7) with x- coordinate 9 , then

x = 9 ← equation of vertical line

Answer:

RXS=48

Step-by-step explanation:

According to the figure,

RXQ+QXS=RXS

or,8x-1+3x+5=5x+28

or,8x+3x-5x=28+1-5

or,6x=24

or, x=24/6

or,x=4

Then,

RXS=5x+28

=5×4+28

=20+28

=48

Answer:

B

Step-by-step explanation:

Using the rule of exponents

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

Given

y = 12 × [tex]3^{x}[/tex] ← substitute x = - 2 into the expression

y = 12 × [tex]3^{-2}[/tex] = 12 × [tex]\frac{1}{3^{2} }[/tex] = 12 × [tex]\frac{1}{9}[/tex] = [tex]\frac{12}{9}[/tex] = [tex]\frac{4}{3}[/tex] → B

Answer:

B

Step-by-step explanation:

y= 12 *3 ^x , substitute x with -2

y=12 *3^-2 , use the rule  a^ - b =  1 /a^b

y= 12 / 3^2 , 3^2 =3*3 = 9

y= 12/9, divide both numbers by 3,  12÷3/ 9÷3

y= 4/3

[tex]\text{Suppose the width of the rectangle is }x\text{ cm}[/tex]

[tex]\text{then the perimeter can be expressed as}[/tex]

[tex]2(24+x)=72[/tex]

[tex]24+x=36[/tex]

[tex]x=12[/tex]

[tex]\text{Therefore the area of the rectangle is }24\cdot x=24\cdot 12=288\text{ cm}{}^2[/tex]

Answer: Solution,

length (l) = 24 cm

perimeter (p)= 74 cm

Area (A) = ?

we know,

P = 2(l + b )

74 = 2( 24 + b)

74 = 48 + 2b

2b = 74 - 48

2b = 26

b= [tex]\frac{26}{2}[/tex]

b = 13

now,

A = l*b

   = 24 * 13

   = 312 cm square

Therefore, the area of the rectangle is 312 cm square.

The range of the function is: (b) {y: y = -7, -2, 3, 8}

The ordered pairs are given as:

(x,y) = {(-1, 8), (0, 3), (1.-2), and (2, -7)}

The range is the set of output values of the function

The y values represent the range.

So, we have:

y = {8, 3,-2, -7}

Hence, the range of the function is:

{y: y = -7, -2, 3, 8}

Answer:

n = 25

Step-by-step explanation:

9 / n+2 = 2/6

can be written as

n+2 / 9 = 6/2

n+2/9 = 3

n+2 = 3 * 9

n+2 = 27

n = 27 - 5

n = 25

Answer:

Step-by-step explanation:

Notice that KL = LM and PQ = QR since OL and OQ are perpendicular to both KM and PR.

It follows that QR = (1/2) PR = 20 cm. We also know that MR = 21.

Now in order to solve the problem we just need OQ=OL

[tex]OQ^2=OR^2-QR^2= 25^2-20^2 =225\\OQ=15[/tex]

Therefore the perimeter of the pentagon is

[tex]OL+LM+MR+RQ+Q)\\= 15+20+21+20+15= 91[/tex]

y=2x+5

2(2x+5)+4x=10

4x+10+4x=10

8x=20

So there's one solution, x=2.5

Answer:

[tex]\frac{a^{5}b }{x^{6} }[/tex]

Step-by-step explanation:

you just need to forget about 0 because whole equation is raised to 0

and anything raise to 0 is 1

so

[tex]\frac{a^{5}b^{4} }{x^{6}b^{3} }[/tex]  law of exponent [tex]a^{n}[/tex] ÷ [tex]a^{m}[/tex] = [tex]a^{n-m}[/tex]

here [tex]b^{4}[/tex] ÷ [tex]b^{3}[/tex] = [tex]b^{4-3}[/tex]

       = [tex]b^{1}[/tex]

so the answer will be

[tex]\frac{a^{5}b }{x^{6} }[/tex]

81 = 2x + 1 + 6x

81 = 8x + 1

81 - 1 = 8x

80 = 8x

80/8 = x

10 = x

Step-by-step explanation:

According to the question,

AB+BC=AC

2x+1+6x=81

8x+1=81

8x=81-1

8x=80

x=80/8

x=10
