Which expression is equivalent to 4x - 2y = 6

180°

Answer:

x=2

Step-by-step explanation:

-3x+1=-5

Subtract 1 from both sides.

-3x=-6

Divide -3 from both sides.

x=2

If f(x)=-5 and f(x)=-3x+1, x=2.

The value of x = -12.

Define Function.

A special relationship where each input has a single output. It is often written as "f(x)" where x is the input value. Example: f(x) = x/2 ("f of x equals x divided by 2")

The given expression is

H(x)=-5/6 x

also, H(x) = 10

so, put H(x) value in given expression,

10 = -5/6 x

Now, solve for 'x'

-5x = 60

x = 60/(-5)

x = -12

Therefore, the value of x = -12

The equation of the line in slope-intercept form would be; y = -12x + 18

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = MX +c

To find the slope of a line, we the rate at which the value of 'y' is increasing as we increase the value of 'x' by one unit.

We have been given the point (1,6) and (2,-6)

y-y₁ = m(x-x₁)

m = (-6-6)/(2 -1)

m = -12/1

Now substitute;

y-y₁ = m(x-x₁)

y- 6 = -12(x- 1)

y- 6 = -12x + 12

y = -12x + 18

Hence, the equation of the line in slope-intercept form would be; y = -12x + 18

Answer:

Exterior angle = 20 degrees

Interior angle = 160 degrees

================================================

Explanation:

The phrasing "Each exterior angle measure is one eighth the measure of each interior angle" means,

exterior = (1/8)*(interior)

That rearranges to

interior = 8*(exterior)

Let's say x is the measure of the unknown exterior angle. That makes 8x the measure of the interior angle

The two must add to 180 to form a straight line.

interior + exterior = 180

8x + x = 180

9x = 180

x = 180/9

x = 20 is the measure of the exterior angle

8x = 8*20 = 160 is the measure of the interior angle

Note how 160+20 = 180 to verify our answers.

We are to determin if the following sequence are arithmetic and also fin their common difference if they are arithmetic.

(1) -3, -9, -27, -81, ................

This sequence is not an arithmetic sequence because theere is no common difference.

-9 - -3 = -27 - -9

-9 + 3 = -27 + 9

-6 ≠ -18

Therefore is not an arithmetic sequcence.

(2) 13, 17, 21, 25, ......................

This sequence is an arithmetic sequence.

It has a commdon difference of 4

17 - 13 = 21 - 17

This sequence is an arithmetic sequence.

It has a common difference of 4

-2 - -6 = 2 - -2

-2 + 6 = 2 + 2

The oil prospector drills wells with a success probability of 0.15. The probability of finding the first productive well in the third attempt is 0.108375 and the probability that the prospector fails to find productive well in the first 5 attempts is  0.26724 or 26.724%

Let Y be the number of drilling trials on which the prospector will find the first productive well. As Y is a geometric random variable with p=0.15 where p is the probability of being successful on any drilling. Let q = 1- p be the probability of being unsuccessful in drilling a well. q = 1 - 0.15 = 0.85

The probability that the first productive well is found on the third attempt is when outcomes are independent

P(Y=3) = q * q * p = 0.85^2* 0.15 = 0.108375

We want to find the probability that 5 wells are drilled and not a productive one is found. That is we need to find p(Y>5). Y is a binomial random variable with several wells drilled at most as n. Given n=5 and p=0.15, q = 0.85

We know the geometric probability is p(y) = [tex]q^{y-1}[/tex]p

Then corresponding probabilities are added

p(Y≤ 5 ) = p(0) + p(1) +p(2) + p(3) +p(4) +p(5)= 0.73276

Using the complement rule:

p(Y>5) = 1 - p(Y≤5) = 1- 0.73276 = 0.26724 = 26.724 %

The value of x for the given triangle is 30°.

According to the question,

We have the following information:

We have a triangle.

Three angles of the triangle are x°, 65° and (x+55)°.

We know that the sum of all the three angles of a triangle is 180°.

So, the sum of these angles will be 180°.

Now, adding three angles:

x° + 65° + (x+55)° = 180°

(2x+120)° = 180°

2x = 180-120

2x = 60

x = 60/2 (2 was in the multiplication on the left hand side. So, it is in the division on the left hand side.)

x = 30°

Hence, the value of x in the angles of the given triangle is 30°.

Given, an integer is subtracted from 8 times the next consecutive odd integer, the difference is -33.

Assuming the first odd integer to be 'n'.

So, the next consecutive odd integers are (n + 2), (n + 4)...

∴ 8(n + 2) - n = - 33.

Now, to find the values of each function we will put the values in place of x.

We will find the value of f(2) by putting 2 in place of x.

f(2) = [tex](2)^{2} -3(2)-4[/tex]

f(2) = 4-6-4

f(2) = -2-4

f(2) = -6

(We know that the numbers with negative sign are added but the result always remains in negative.)

We will find the value of f(4) by putting 4 in place of x:

f(4) = [tex](4)^{2} -3(4)-4[/tex]

f(4) = 16-12-4

f(4) = 4-4

f(4) = 0

Now, we will find the value of f(-3) by putting -3 in place of x:

The dimensions are Width = 7 feets ; length = 20 feets

As given,

Meadow area is 140 square feet.

Height = W (smaller dimension and 2 sides)

Height = L (longer dimension and 1 side)

Fence yards equal 34 feet;

Hence,

L + W = 34

L + 2W = 34

L = 34 - 2W - - - (1)

Recall:

Area = L * W = 140

Substitute value of L

140 = (34 - 2W) * W

140 = 34W - 2W²

2W² - 34W + 140 = 0

W² - 17W + 70 = 0

W² - 10W - 7W + 70 = 0

W(W - 10) - 7(W - 10) = 0

(W - 10) = 0 or (W - 7) =0

W = 10 or W = 7

We choose the shorter width because length should be as long as possible:

W = 7
