1/4 × s = 15

s = 15 : 1/4

s = 15 × 4

s = 60

[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]

[tex] \sf \: \frac{1}{4s} = 15 \\ [/tex]

Variable s cannot be equal to 0 as division by zero is not defined. Multiply both sides of the equation by 4s.

[tex] \sf \: 1=60s [/tex]

Swap sides so that all variable terms are on the left-hand side.

[tex] \sf \: 60s=1 [/tex]

Divide both sides by 60.

[tex] \sf \: s= \boxed{ \bf\frac{1}{60}}\:\sf\approx 0.0166... \\ [/tex]

Answer:

No

Step-by-step explanation:

Inverse f(x) into f(x)^-1.

x = 2y + 4

Solve for y.

x -4 = 2y

x/2 - 2 = y

y = x/2 - 2

No.

These circles are tangent .

Two circles are tangent to each other if they have only one common point. Two circles that have two common points are said to intersect each other. Two circles can be externally tangent if the circles are situated outside one another and internally tangent if one of them is situated inside the other.

According to the question

These circles are :

A > Concentric

This option is incorrect because circle are concentric if and only if they have common center .

B> none of these

This option is incorrect .

C > Tangent

This option is correct as Two circles are tangent to each other if they have only one common point and in the figure there is only one common point between both circles .

D> Congruent

This option is incorrect as this two circles have different size but in congruent both circle should be same size which is not possible here.

Hence, These circles are tangent .

Answer:

Value of k is 9

Step-by-step explanation:

-2x + 8 = -10

-2x = -10 - 8

-2x = -18

x = -18/-2

x = 9

f(x) = f(k)

x = k

9 = k

Hello there!

We are given the function:

[tex] \displaystyle \large{f(x) = - 2x + 8}[/tex]

We want to find the value of k. First, we know that f(k) is -10. We substitute x = k and f(x) = -10.

[tex] \displaystyle \large{f(k) = - 2k + 8} \\ \displaystyle \large{ - 10 = - 2k + 8}[/tex]

Solving the equation. First, we subtract both sides by 8.

[tex] \displaystyle \large{ - 10 - 8 = - 2k +8 - 8} \\ \displaystyle \large{ - 18 = - 2k} \\ [/tex]

Divide both sides by -2.

[tex] \displaystyle \large{ \frac{ - 18}{ - 2} = \frac{ - 2k}{ - 2} } \\ \displaystyle \large{ 9= k}[/tex]

Therefore, k = 9

When we substitute k = 9 in f(k), the value is -10.

Topic: Linear Function

The answer is infinitely many solutions because 0 = 0.

If you don't seem to see where I got 0 = 0, look at the equation,

4b – 4b = 0

first lets do the math on the left side.

4b - 4b  is equal to 0.

so lets put 0 on the left side, now lets look at the equation all together,

0 = 0,

and this means that it has infinitely many solutions.

The reason why it is not no solution because no solution means when there are no answers to the equation. For example, the solution is not true, such as the equation 24 ≠ 29. This is a no solution equation. One solution can be 4x = 20, as x = 5, concluding it being one solutions.

Answer:

Greta is correct.

Step-by-step explanation:

The variable that is lower in each scenario is the variable that should have a coefficient (unless there are fractions).  Greta's equation makes sense because it's saying that in order for the # of trees to = the # of people, you need to multiply x by 4, or 4x.

Answer:

[tex]\displaystyle \frac{ 1 }{3} [/tex]

Step-by-step explanation:

we would like to compute the following limit:

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} [/tex]

if we compute the limit from numerator to denominator directly,we'd end up with

[tex] \dfrac{ \infty }{ \infty } [/tex]

which is an indeterminate form so we must do it in a different way. well to compute this limit,we can consider factoring method . notice that we can factor the numerator and that yields

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{ {n}^{2} ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]

remember that ,

thus we acquire:

[tex]\displaystyle \lim_{n \to \infty } \frac{ {n} \sqrt{ ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]

reduce fraction:

[tex]\displaystyle \lim_{n \to \infty } \frac{ {} \sqrt{ 4 {}^{} + \frac{3}{n} } }{6} [/tex]

as n approaches to ∞ ,3/n approaches to 0 which yields:

[tex]\displaystyle \frac{ \sqrt{ 4 {}^{} } }{6} [/tex]

simplify square root:

[tex]\displaystyle \frac{ 2 }{6} [/tex]

reduce fraction:

[tex]\displaystyle \frac{ 1 }{3} [/tex]

hence,

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} = \boxed{ \frac{1}{3} }[/tex]

and we're done!

Step-by-step explanation:

Answer:

9 is a constant

These are the true statements.

Step-by-step explanation:

the coefficient is only the number in a term

the constant is a number by itself in an expression.

The absolute value of inequality is 180 ≤  x ≤  200 and its solution lies in [180, 200].

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

Suppose the operating temperature be x.

Then, as per the question the absolute difference of the temperature and 190°F is within 10°F.

It can be written in the form of inequality as follows,

|x - 190| ≤ 10

⇒ x - 190 ≤ 10 and  x - 190 ≥ -10

⇒ -10 ≤ x - 190 ≤ 10

⇒ -10 + 190 ≤ x ≤ 10 + 190

⇒ 180 ≤  x ≤  200

Thus, the range of acceptable temperatures lie in [180, 200].

Hence, the absolute value of inequality and its solution are given by  180 ≤  x ≤  200 and [180, 200] respectively.

Answer: the simplest form is 4/7

Step-by-step explanation:

Step-by-step explanation:

let's say, 7 - 4 = 3

that contradicts the statement that both numbers are odd.

no, they are 7, 4, with 4 being even (and not odd).

in fact, as with sums and subtractions in general, it requires an odd and an even number to produce an odd result.

odd with odd always delivers an even result. as does even with even.

Answer:

2nd option

Step-by-step explanation:

Given

2x - 6 = 22 ( isolate the x- term by adding 6 to both sides )

2x = 28 ( divide both sides by 2 )

x = 14

Answer:

Add 6 to both sides, then divide by 2. The solution is x = 14

Step-by-step explanation:

Add 6 to both sides:

[tex](2x - 6) + 6 = 22 + 6 \\ 2x = 28[/tex]

And then divide by 2:

[tex] \frac{2x}{2} = \frac{28}{2} [/tex]

The solution is 14

Answer:

x^2-7x+4

Step-by-step explanation:

4x^2 -3^2 is basically 4-3, leaving you with 1.

-3x-4x, you're adding to the negative value of -3x, giving -7x.

-4-(-8), a little tricky at first. a trick that i was taught is if you're subtracting a number with a negative number, treat it as if you're adding, therefore -4-(-8) = -4+8, giving you a positive 4.
