Consider the relation (9,8) (2,6) (1,5) (8,3) (5,7)

What is the domain of the relation?

Enter each value on the same line, separated by commas.

Answer:

length = 8

width = 4

Step-by-step explanation:

Area = length x breadth

Let x represent the width

length = x + 4

32 = x × (x + 4)

32 = x² + 4x

x² + 4x  - 32  = 0

solving using quadratic equation =

(x² - 4x) -32 + 8x

x = 4 or -8

since width cannot be a negative number, we would use 4

Answer:

166

Step-by-step explanation:

A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

A=2(wl+hl+hw)=2·(7·5+4·5+4·7)=166

A = 166

Hope this helps

Answer:

[tex] \frac{k}{5} = 7 \\ k = 5 \times 7 \\ \boxed{k = 35}[/tex]

k=35 is the right answer.

Answer:

First Question: 75 x [tex]10^{3}[/tex] and 7.5 x [tex]10^{4}[/tex]

Second Question:

A = bh (parallelogram)

A = 1/2bh (triangles)

Step-by-step explanation:

First Question: It's multiplied by [tex]10^{3}[/tex] because 75,000 has 3 zeros.

It's also multiplied by [tex]10^{4}[/tex] because you move the decimal place 4 times on the right at 7.5 which leads to 75,000.

Second Question: Well there aren't specific numbers to solve the areas of the parallelogram or triangle, so I gave the formulas instead. "b" stands for base and "h" stands for height

Hope this helped! <3

Answer:

69

Step-by-step explanation:

Answer: C. 2.889 .

Step-by-step explanation:

To find : A decimal expression equivalent to [tex]\dfrac{26}{9}[/tex] .

When we divide 26 by 9 , we get 2.88888888889 which is approximately equal to 2.889  [Round off to the nearest thousandth place]

Hence, the decimal is equivalent to[tex]\dfrac{26}{9}[/tex]  is 2.889.

Hence, the correct option is C. 2.889 .

Answer:

2.8 with the _ above the 8 dont listen to that other guy/girl

Answer:

-3.44 times 10^10

Step-by-step explanation:

Answer:

Equation for question number 1:

y = -6x -1

Equation for question number 2:

y = 6x

OR

y = 6x + 0

btw, if you want to know how to solve the equations by urself, the equation is y = mx + b

m = slope

b = starting point / intercept

hope this helps!

Answer:

x>-6

Step-by-step explanation:

Subtract 8 from both sides.

2x+8−8>−4−8

2x>−12 Divide both sides by 2.

x>-6

Answer: A) “Two X Plus 8 Is Greater Than Negative Four”

B) 2x + 8 > -4, Then subtract 4 from 8 so now it is 2x > -12. Then divide -12 by 2. Your answer will be X > -6 I hope that this helps you

Answer:

DF = 10 units

[tex]m\angle DFG = 28^\circ[/tex]

EG = 5.04

Step-by-step explanation:

Properties of Rhombus es

The image contains a rhombus with the following data (assume the center as point O):

DO = 5 units

GF = 5.6 units

[tex]m\angle FEO = 62^\circ[/tex]

4. Calculate DF

Applying property 4, diagonals bisect each other, thus the length of DF is double the length of DO, i.e. DF=2*5 = 10:

DF = 10 units

5. Calculate [tex]m\angle DFG[/tex]

Applying property 4 in triangle EFO, the center angle is 90°, thus angle EFO has a measure of 90°-62°=28°.

Applying property 5, this angle is half of the measure of angle EFG and angle DFG has the same measure of 28°.

[tex]m\angle DFG = 28^\circ[/tex]

6. FG is the hypotenuse of triangle OFG, thus:

[tex]OG^2=FG^2-OF^2[/tex]

[tex]OG^2=5.6^2-5^2[/tex]

[tex]OG^2=6.36[/tex]

[tex]OG=\sqrt{6.36}=2.52[/tex]

EG is double OG: OG=2*2.52=5.04

EG = 5.04

Answer:

65°

Step-by-step explanation:

They are corresponding angles if M and N are parallel

Answer:

m∠b = 65°

Step-by-step explanation:

∠b and the 65° angle are known as corresponding angles meaning they are equivalent. Therefore, m∠b is 65°.

Answer: 4000

Step-by-step explanation:

Answer:

its 4000 right

Step-by-step explanation:

1000

x    4

-------

4000

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

[tex]x^2\:-16x\:+\:39\:=\:0[/tex]

Subtract 39 from both sides

[tex]x^2-16x+39-39=0-39[/tex]

Simplify

[tex]x^2-16x=-39[/tex]

Rewrite in the form x² + 2ax + a²

solve for a, 2ax = -16x

2ax = -16x

divide both sides by 2a

2ax/2x = -16x/2x

a = -8

Add a² = (-8)² to both sides

[tex]x^2-16x+\left(-8\right)^2=-39+\left(-8\right)^2[/tex]

simplify

[tex]x^2-16x+\left(-8\right)^2=25[/tex]

Apply perfect square formula:  (a-b)² = a² - 2ab + b²

[tex]\left(x-8\right)^2=25[/tex]           ∵ [tex]x^2-16x+\left(-8\right)^2=\left(x-8\right)^2[/tex]

Thus,

[tex]\left(x-8\right)^2=25[/tex]

BONUS! EXTENDED SOLUTION!

We can further solve for x such as

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

solve

[tex]x-8=\sqrt{25}[/tex]

[tex]x-8=\sqrt{5^2}[/tex]

[tex]x-8=5[/tex]        

[tex]x=13[/tex]

similarly,

[tex]x-8=-\sqrt{25}[/tex]

[tex]x-8=-5[/tex]

[tex]x=3[/tex]

Therefore,

[tex]x=13,\:x=3[/tex]

Answer: The answer is C) y= 2/3x-3

Step-by-step explanation:

i figure it out

Answer:

C

Step-by-step explanation:

so obviously your slop is 2/3. so it starts with y=2/3. so B is out of the question. since the slope is x in the equation, you still have to add the x in the equation; y=2/3x
