The equation of the straight line passing through the point (3, 3)

which is perpendicular to the line y=-1/2x-4 is y= 2x-3

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept.

The equation for a straight line is y = mx + c. (1)

The line is parallel to the equation y=-1/2 x-4 ....(2),

meaning that the value of m in equation (1) is 2 y = 2x + c

The needed line has the equation y= 2x-3 since it goes through the point (3,3) where 3=2(3)+c provides c=-3.

Applying the sine ratio, the length of CD is calculated as: 12.687 cm.

The sine ratio is stated as:

sin ∅ = opposite length / hypotenuse length of a right triangle.

Use the Pythagorean theorem to find BC:

BC = √(AC² - AB²)

AC = 12 cm

AB = 6 cm

Plug in the values

BC = √(12² - 6²)

BC = √(144 - 36)

BC = √108

Find the length of CD using the sine ratio:

∅ = 55

Opposite length = BC = √108

Hypotenuse length = CD

Substitute

sin 55 = √108/CD

(CD)(sin 55) = √108

CD = √108/sin 55

CD ≈ 12.687.

Therefore, applying the sine ratio, the length of CD is calculated as: 12.687 cm.

For x = 80 and y = 130, l and m will be parallel to j and n respectively.

If two lines are parallel, then the sum of the interior angles is supplementary.

Thus, if m || n, then (x - 30) and (x + 50) will be supplementary

⇒ (x - 30) + (x + 50) = 180

x - 30 + x + 50 = 180

2x + 20 = 180

2x = 180 - 20

2x = 160

x = 80

Thus, if x = 80, then k will be parallel to l

Now, if m || n, then y and (x - 30) must be supplementary

⇒ (x - 30) + y = 180

x - 30 + y = 180

we found that x = 80

⇒ 80 - 30 + y = 180

50 + y = 180

y = 180 - 50

y = 130

Thus, if y = 130 then, k will be parallel to l.

The solved logarithmic function is 2x - y = e and x + y = 8 for log (2x - y) = 1 and log (x + y) = 3 log 2 respectively.

What is a logarithmic and exponential function?

Logarithmic functions and exponential functions are inverses of each other. The logarithmic function is denoted by using the word log while exponential by using the alphabet,  e. For example log 10 = 1 and e^2.

Solving the given expressions: log (2x - y) = 1 and log (x + y) = 3 log 2

Applying given properties of logarithmic and exponential function;

log a + log b = log (ab)

4 log x = log x⁴

e^(log x) = 1

e^(x + y) = (e^x) × (e^y)

Take expression, log (2x - y) = 1

Applying exponential on both sides, we get,

e^(log 2x - y) = e^1

2x - y = e

To Check Results,

Taking logarithm both sides,

log (2x - y) = log e

log (2x - y) = 1

Thus, the answer is verified.

Take expression, log (x + y) = 3 log 2

Applying exponential on both sides, we get,

e^(log (x + y) = e^(3 log 2)

x + y = e^(log 8)

x + y = 8

To Check Results,

Taking logarithm both sides,

log (x + y) = log 8

log (x + y) = 3 log 2

Thus, the answer is verified.

Hence, the solved expression is 2x - y = e and x + y = 8 for log (2x - y) = 1 and log (x + y) = 3 log 2 respectively.

16. Constant of variation, k = 1/4

17. Constant of variation, k = 1

A direct variation is a proportional relationship where variable x varies directly with variable y. The equation of a direct variation is modelled by the equation below:

y = kx.

k is the constant of proportionality of the relationship between x and y. It is also referred as the unit rate. On a proportional or direct variation graph, it can be determined by using any point on the graph (x, y) to find k.

k = y/x.

All graphs that represent direct variations passes through the origin (0, 0). The coordinate of the constant of proportionality of a direct variation graph is (1, k), where the constant of variation = k, and x = 1.

14. The graph passes through the origin (0, 0), so it represents a direct variation.

Constant of variation, k = 3/2

Step-by-step explanation:

Answer:

One number is -6 and the other number is 7.

Step-by-step explanation:

Let x be one of the numbers and y be the other number.

So 8x + 5y = -13.

Also, x + y = 1

These two equations are the algebraic version of the words in the problem.

We need to solve this system of equations. You may be studying solving systems of equations using substitution or elimination method or even matrices. I will show you here using elimination method, sometimes called addition or subtraction method.

We need to multiply x+y=1 by -5.

-5(x + y = 1)

-5x - 5y = -5

We can stack the two equation and add them together to eliminate one of the variables.

8x + 5y = -13

-5x - 5y = -5

___________ Add.

3x = -18

3x = -18 Now divide by 3.

x = -6

Put thus value back into one of the original equations.

x = -6

x + y = 1

Substitute.

-6 + y = 1

Add 6.

y = 7

When one number is -6 and the other number is 7, then both equations will be true.

When the value of the variable x is greater than or equal to -3, the result returned by the even function is 3.

x=-1x=−1x, equals, minus, 1, Then the correct option is C.

A true function f(x) is an even function if the yield value of the function f(-x) is the same as the value returned by the function f(x) for all values of x that fall within the domain of f.

It is recommended that the equation be saved in an even function:

f(-x) = f(x)

Therefore

f(x) = f(3) = 3

Let's assume that f(x) is a function that always returns even. Then there is also

f(-3) = f(3) = 3

x + 2 =  (3³)⁴/₃

Cancelling 3 on Right Hand Side of the equation

x + 2 = 3⁴

Solving Right Hand Side of the equation

x + 2 = 81

Step-by-step explanation:

For right triangle has a line of symmetry two sides of the triangle have the same length and two angles of the triangle have the same measure.

A triangle is a three-sided polygon that consists of three edges and three vertices.

A right angle triangle is a triangle in which one angle is a right angle, i.e., in which two sides are perpendicular.

If a right triangle has a line of symmetry then two sides of triangle will have same length and two angles are equal.

For a triangle to have a line of symmetry, it must be an isosceles triangle, meaning two of it’s sides and two of it’s angles must be the same.

From there it follows that for a right triangle to have a line of symmetry it must be an isosceles right triangle, meaning it must either have two 90-degree angles, or two identical non-90-degree angles.

Hence for right triangle has a line of symmetry two sides of the triangle have the same length and two angles of the triangle have the same measure.

The distance being proportional to the time Hector walked 2 km in 18 minutes.

Two variables are proportional if they can be written in the form ak=b where k is the proportionality constant.

Here the proportionality constant is speed.

Speed is defined as the distance covered in unit time. The unit of speed can be written as kilometer per hour, miles per hour or meters per second.

The distance is proportional to the time walked therefore:

1.5/2=13.5/T₁

or, T₁=18

Similarly:

1.5/4.5=13.5/T₂

Because the squared equation can have negative roots.

If the equation you're given already includes the squared variable (and you don't multiply by the variable yourself), then you don't need to worry about the extraneous root. Both solutions will be correct because the variable was already squared.

You only need to worry about the extraneous root in the case of a quadratic equation if you made the equation quadratic by multiplying by a variable. Any time you square a negative number or a variable (which may be negative), you risk losing information by making it positive. That means that, if you square a variable (especially for variables on both sides of the equation, which can easily hide a negative) or a negative number, you should always do a quick plug-in and check.
