Answer:

The two numbers are 100 and 10

Step-by-step explanation:

Let's call the two numbers x and y.

x-y=90 \\\\x\div y=10

Add 7 to both sides of the first equation to isolate x:

x=90+y

Substitute:

(90+y)\div y=10 \\\\90+y=10y \\\\90=9y \\\\y=10 \\\\x=100

Hope this helps!

Answer:

x = 100

y = 10

Step-by-step explanation:

<em>Let the two numbers be x and y</em>

<u><em>Condition 1:</em></u>

x - y = 90  ----(1)

<u><em>Condition 2:</em></u>

\frac{x}{y} = 10   --------(2)

<em>Taking eq (1)</em>

x - y = 90

x = 90+y -----(3)

<em>Putting ep (3) in (2)</em>

\frac{90+y}{y} = 10

=> 90+y = 10y

=> 90 = 10y-y

=> 90 = 9y

<em>Dividing both sides by 9</em>

=> y = 10

<em>Putting y = 10 in eq (1)</em>

=> x-10 = 90

=> x = 90+10

=> x = 100

Answer:

A. y=3x-10

C. y+6=3(x-15)

Step-by-step explanation:

Given:

The given line is 6x+18y=5

Express this in slope-intercept form y=mx+b, where m is the slope and b is the y-intercept.

6x+18y=5\\18y=-6x+5\\y=-\frac{6}{18}x+\frac{5}{18}\\y=-\frac{1}{3}x+\frac{5}{18}

Therefore, the slope of the line is m=-\frac{1}{3}.

Now, for perpendicular lines, the product of their slopes is equal to -1.

Let us find the slopes of each lines.

Option A:

y=3x-10

On comparing with the slope-intercept form, we get slope as  m_{A}=3.

Now, m\times m_{A}=-\frac{1}{3}\times 3=-1. So, option A is perpendicular to the given line.

Option B:

For lines of the form x=a, where, a is a constant, the slope is undefined. So, option B is incorrect.

Option C:

On comparing with the slope-point form, we get slope as  m_{C}=3.

Now, m\times m_{C}=-\frac{1}{3}\times 3=-1. So, option C is perpendicular to the given line.

Option D:

3x+9y=8\\9y=-3x+8\\y=-\frac{3}{9}x+\frac{8}{9}\\y=-\frac{1}{3}x+\frac{8}{9}

On comparing with the slope-intercept form, we get slope as  m_{D}=-\frac{1}{3}.

Now, m\times m_{D}=-\frac{1}{3}\times -\frac{1}{3}=\frac{1}{9}. So, option D is not perpendicular to the given line.

Explain why the initial value of any function of the form<br> f(x) = a(bx) is equal to a.
Serggg [28]

Answer:

Step-by-step explanation:

f(x) = a(b^x), the initial value is always a, because a is independent of x , so when x changes only b^x changes.ex if  a = 2, b = 3, and x = 0: f(0) = 2 (3^0) = 2  If x = 1, then f(1) = 2 (3^1) = 2 (3). If x = 2, then f(2) = 2 (3^2) = 2 (9), as you can see a still the same.

Which statement is not true <br> 3+4+5=4+3+5<br> (6-3)=4+(6-3)<br> 6+6-3=6-6+3
Mandarinka [93]

Answer:

The second one is not true the left side 3 does not equal the left side 7, which means it is not true.

The third one is also not true because the left side 9 does not equal the left side 3, which also means it is not a true statement
