8x=24 which is 3 so x = 3

4y=24 which is 6 so y = 6
(3,0) for x and (0,6) for y

Question 1*

worty [1.4K]

Given expressions;

f(x) = x² + 6x + 7

g(x) = 8x² - 2

h(x) = 3x + 4

k(x) = x - 3

Find f(2) - g(2). k(2)

f(2) = 2² + 6(2) + 7 = 23

g(2) = 8(2)² - 2 = 30

k(2) = 2 - 3 = -1

Now, f(2) - g(2). k(2) = 23 - (30)(-1)

= 53

The solution to the problem is 53

For the following right triangle find the side length x round your answer to the nearest hundredth

pashok25 [27]

Answer:

x ≈ 12.96

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 11² = 17²

x² + 121 = 289 ( subtract 121 from both sides )

x² = 168 ( take the square root of both sides )

x = $\sqrt{168}$ ≈ 12.96 ( to the nearest hundredth )

Answer:

log2(0.25) = -2

512 = 8^3

Step-by-step explanation:

<em>Use of formula: </em><em>loga (b) = c ⇔ b = a^c</em>

Rewrite the following equation in logarithmic form. 0.25 = 2^-2

log2(0.25) = -2

Rewrite the following equation in exponential form. log8 (512) = 3

512 = 8^3

Aarón made a picture frame with the dimensions show in the figure what is the area of the picture

tatuchka [14]

Answer:

Area of the picture is $72\textrm{ }cm^{2}$

Step-by-step explanation:

Given:

Outer rectangle dimensions are 10 cm by 12 cm.

Inner rectangle dimensions are 6 cm by 8 cm.

Area of the picture given as:

$Area=\textrm{Outer rectangle area}-\textrm{Inner rectangle area}$

Outer rectangle area = $10\times 12=120\textrm{ }cm^{2}$

Inner rectangle area = $6\times 8=48\textrm{ }cm^{2}$

Therefore, the area of the picture is given:

$Area=120-48=72\textrm{ }cm^{2}$
