A) f(x) = 4•(2)^x

When substituting in the values of x and y into the functions, the only function that works for both (0,4) and (1,8) is A.

8 = 4•(2)^1 = 4 x 2 = 8

4 = 4•(2)^0 = 4 x 1 = 4

Answer:

x = - 1

Step-by-step explanation:

Length ( l ) = 2x + 8 cm

Width / Breadth ( b ) = 2 cm

Area ( rectangle ) = 12 cm

Formula : -

Area ( rectangle ) = lb

12 = ( 2x + 8 ) ( 2 )

Divide 2 on both sides,

12 / 2 = ( 2x + 8 ) ( 2 ) / 2

6 = 2x + 8

2x + 8 = 6

2x = 6 - 8

2x = - 2

x = - 2 / 2

x = - 1

Answer:

Mixed Number: 5 [tex]\frac{7}{10}[/tex]

Improper Fraction:[tex]\frac{57}{10}[/tex]

Step-by-step explanation:

A mixed number is when you express the decimal as a fraction, 0.7 is the same as [tex]\frac{7}{10}[/tex], so 5[tex]\frac{7}{10}[/tex] is your answer.

An improper fraction is a fraction where the numerator is bigger than the denominator, to do this you multipy the whole number 5, which can be written as [tex]\frac{5}{1}[/tex], by [tex]\frac{10}{10}[/tex].

[tex]\frac{5}{1}[/tex]·[tex]\frac{10}{10}[/tex]=[tex]\frac{50}{10}[/tex]

Then add 0.7, or [tex]\frac{7}{10}[/tex].

[tex]\frac{50}{10}[/tex]+[tex]\frac{7}{10}[/tex]=[tex]\frac{57}{10}[/tex]

Answer:

x² + y² = 12

Step-by-step explanation:

x + y = -4

xy = 2

x² + y² = (x+y)² - 2xy = (-4)² - 2(2) = 16 - 4 = 12

Answer:

m< WXZ = 73

m< ZXY = 87

Step-by-step explanation:

WXY = WXZ + ZXY

WXY = 5x+8+7x-4

WXY = 12x+4

m < WXY = 160

160 = 12x + 4

156 = 12x

13 = x

WXZ = 5x + 8

= 5*13 + 8

= 73

ZXY = 7x - 4

= 7*13 - 4

= 87

[tex]\\ \sf\Rrightarrow 5x+8+7x-4=160[/tex]

[tex]\\ \sf\Rrightarrow 12x+4=160[/tex]

[tex]\\ \sf\Rrightarrow 12x=156[/tex]

5\sqrt{2} + \sqrt{10}

Step-by-step explanation:

I assume the exp as [tex]\sqrt{5} (\sqrt{10} + \sqrt{2} )[/tex]

[tex]\sqrt{50 } + \sqrt{10}[/tex]

[tex]\sqrt{25*2} +\sqrt{10}[/tex]

[tex]5\sqrt{2} + \sqrt{10}[/tex]

The simplified form of the given expression [tex]\sqrt{5} (\sqrt{10} +\sqrt{2} )[/tex] will be  [tex]5\sqrt{2} + \sqrt{10}[/tex].

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

The given expression is as follows;

[tex]\sqrt{5} (\sqrt{10} +\sqrt{2} )\\\\\sqrt{5} \times \sqrt{10} +\sqrt{5} \times\sqrt{2} \\\\\sqrt{25 \times 2} +\sqrt{10}\\\\5\sqrt{2} +\sqrt{10}[/tex]

Hence, the simplified form of the given expression is [tex]5\sqrt{2} + \sqrt{10}[/tex].

Answer:

y = - x + 4

Step-by-step explanation:

First find slope:

6-1/-2-3 = 5/-5 = -1

Then plug one point and slope into point slope form: y-y1 = k (x-x1)

Plug in (3, 1) and slope -1 --> y-1 = -1(x-3)

Simplify --> y - 1 = - x + 4

Then add 1 to both sides --> y = -x + 4
