Answer:

10h^2

Step-by-step explanation:

i dont remember

Answer: 10h^2

Step-by-step explanation:

You’re gonna wanna combine your like terms, so…

([6h^2 + 8h^2] - 4h^2)

(14h^2 - 4h^2 = 10h^2)

So your answer would be: 10h^2

Answer:

x = 1/2

Step by step explanation:

Two numbers a and b are each greater than zero.

i.e a > 0 and b > 0

And;

[tex] \sqrt{a} \: = \: \sqrt[3]{b} [/tex]

Since the square root of a is equal to cube root of b then,

a = b = 1

[tex] {a}^{2x \: - \: 1} \: = \: b[/tex]

[tex] {1}^{2x \: - \: 1} = {1}^{0} [/tex]

2x - 1 = 0

x = 1/2

Two numbers are 'a' and 'b'.

And a > 0, b > 0

[tex]\sqrt{a}=\sqrt[3]{b}[/tex]

[tex]a^{\frac{1}{2} }=b^{\frac{1}{3}}[/tex]

[tex]a=(b)^{\frac{2}{3} }[/tex]

We have to find the value of [tex]x[/tex] if [tex]a^{2x-1}=b[/tex],

By substituting the value of [tex]a[/tex] in the given expression,

[tex](b^{\frac{2}{3}})^{2x-1}=b[/tex]

Now use the laws of exponents,

[tex]b^{\frac{2}{3}(2x-1)}=b[/tex] [Since, [tex](a^m)^n= a^{mn}[/tex]]

By comparing the exponents on both the sides,

[tex]\frac{2}{3}(2x-1)=1[/tex]

[tex]2(2x-1)=3[/tex]

[tex]4x-2=3[/tex]

[tex]4x=5[/tex]

[tex]x=\frac{5}{4}[/tex]

[tex]x=1.25[/tex]

Answer:

ummm I think u want the answer x= 11 1/4

Answer:

x = 45/4

Step-by-step explanation:

4(x - 5) = 25

4x - 20 = 25

4x - 20 + 20 = 25 + 20

4x = 45

4x/4 = 45/4

x = 45/4

Answer:

y = -3/4x + 14

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal of the original line.

4/3x -> -3/4x

Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].

11 = -3/4(4) + b

11 = -3 + b

14 = b

Put everything we know and solved for back into the expression.

y = -3/4x + 14

Best of Luck!

Answer:

- 3

Step-by-step explanation:

Given

7 - 2h ( substitute h = 5 into the expression )

= 7 - 2(5)

= 7 - 10

= - 3

On evaluating the function at h = 5, we get -

f(5) = - 3.

We have a function -

f(h) = 7 - 2h

We have to find the value of f(h) at h = 5.

f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )

f(2) = Sin( [tex]\frac{\pi }{2}[/tex] )

f(2) = 1

According to the question, we have -

f(h) = 7−2ℎ

Now, evaluating the function at h = 5, we get -

f(5) = 7 - 2 x 5 = -3

Hence, on evaluating the function at h = 5, we get -

f(5) = - 3.

Graphs are used to show the relationship between two variables. In the given graph, as the value of x increases, the value of y decreases.

Given that:

[tex]y = \frac{10}{x}[/tex]

The above function is an inverse function.

This means that:

As the value of x increases, the value of y decreases

Take for instance:

[tex]x= 1[/tex]

[tex]y = \frac{10}{1} = 10[/tex]

Now, [tex]x = 2[/tex]

[tex]y = \frac{10}{2} = 5[/tex]

Notice that:

As x increases from 1 to 2, the corresponding values of y decreases from 10 to 5

Hence, (b) is correct

Step-by-step explanation:

If a 6-foot board is cut in two pieces, both lengths could be anything that add up to 6 feet since the problem did not specify where the board was cut.

So if one piece is x feet long, the other must be 6 - x feet long because:
