Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation

Olenka [21]

Answer:

y = $\frac{49}{3}$

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 7 when x = 3

k = $\frac{y}{x}$ = $\frac{7}{3}$ , thus

y = $\frac{7}{3}$ x ← equation of variation

When x = 7, then

y = $\frac{7}{3}$ × 7 = $\frac{49}{3}$

Thx in advance for the help

Answer: $x\geq 13$

Step-by-step explanation:

Given

The inequality is $2x-7\geq 19$

adding both side 7

$2x-7+7\geq 19+7\\2x\geq 26$

Multiply both sides by $\frac{1}{2}$

$\dfrac{1}{2}\times 2x\geq 26\times \dfrac{1}{2}\\\\x\geq 13$

the shaded region in the figure indicates the solution set.

3i = 105

To make i by itself, divide both sides by i.

i = 35

There you have it, 35 is the answer.

Five years from now, the sum of the ages of a women and her daughter will be 40 years. The difference in their present age is 24

CaHeK987 [17]

Answer:

Her daughter is <u>3 years</u> old now.

Step-by-step explanation:

Given:

Five years from now, the sum of the ages of a women and her daughter will be 40 years.

The difference in their present age is 24 years.

Now, to find how old is her daughter now.

Let the age of daughter be $x\ years$ .

And the age of mother be $y\ years$ .

According to question:

$(x+5)+(y+5)=40$

⇒ $x+y+10=40$

<em>Subtracting both sides by 10 we get:</em>

⇒ $x+y=30$

⇒ $x=30-y$ ............( 1 )

Now, as given in question:

The difference in their present ages is 24 years.

$x-y=24$

Putting the equation ( 1 ) in the place of $x$ we get:

⇒ $(30-y)-y=24$

⇒ $30-2y=24$

<em>Moving variable on one side and the numbers on the other:</em>

⇒ $30+24=2y$

⇒ $54=2y$

<em>Dividing both sides by 2 we get:</em>

⇒ $27=y$

So, <em>the age of the mother is 27 years.</em>

Now, putting the value of $y$ in equation( 1 ) we get:

$x=30-27$

⇒ $x=3$

<em>The age of daughter is 3 years.</em>

Therefore, her daughter is 3 years old now.
