Answer:

y=50 and x=-173/2

Step-by-step explanation:

52-2y=-48

∴-2y=-100

y=50

and 2x+3y=-23

y=50→(1)

2x+3y=-23→(2)

Putting y=50 in equation (2), we get

⇒2x+3y=-23

⇒2x+3(50)=-23

⇒2x+150=-23

⇒2x=-23-150

⇒2x=-173

⇒x=-173/2

∴y=50 and x=-173/2

Answer:

csc 2 (csc [tex]\frac{5\pi}{6}[/tex] = csc 150 = csc 30 = csc 2)

Step-by-step explanation:

csc [tex]\frac{5\pi}{6}[/tex] is in the 2nd Quadrant where only sin, and csc are positive.

csc [tex](\frac{5\pi}{6})=csc (\pi -(\frac{5\pi}{6}))=csc(\frac{5\pi}{6})[/tex]

but csc [tex]\frac{5\pi}{6}[/tex] = [tex]\frac{1}{sin (\pi/6)} = \frac{1}{sin 30} = \frac{1}{1/2} =2[/tex]

Answer:

(-infinity, -2) ∪ (-2, infinity)

Step-by-step explanation:

I will have to assume that you meant

f(x)=(x-3)/(x+2).  You must use parentheses to specify the order of operations in this problem.

x can take on any value except -2, at which the function is undefined.

Thus, the domain is (-infinity, -2) ∪ (-2, infinity)

Answer:

they are equal

Step-by-step explanation:

Answer:

I believe 14 but I'm not sure

Answer:The given equation is of the form y = mx + b where m is the slope and b is the y-intercept.

Here, m = -14

Two parallel lines have the same slope. So, the slope of the new line will be -14.

To calculate the y-intercept substitute x=4 and y=4 in the equation.

4 = (-14)(4) + b

Solving for b, we get b = 60.

So, the new equation will be y = -14x + 60

Answer:

[tex]y = 3x +4[/tex]

Step-by-step explanation:

Given

[tex]m = 3[/tex] --- slope

[tex](x,y) = (-2,-2)[/tex]

Required

Determine the equation and plot the graph

The formula for the equation is:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 3(x - (-2)) - 2[/tex]

[tex]y = 3(x +2) - 2[/tex]

Open bracket

[tex]y = 3x +6 - 2[/tex]

[tex]y = 3x +4[/tex]

Answer:

1. tan

2. standard

3. y=16.8

Step-by-step explanation:

1. Trigonometic functions are:

sinA=opposite/hypoteneuse

cosA=adjacent/hypoteneuse

tanA=opposite/adjacent.

We have the opposite side (20) and the adjacent side (y), but not the hypoteneuse, ao we have to use tan.

2.Inverse is only used when we dont know the angle measure, so we use standard.

3.tanA=opp/adj

tan50=20/y

1.19175359259=20/y

y=16.7819926235 or 16.8

6/8 and 3/8

4 = 2²

8 = 2³

LCM = 2 × 2 × 2

LCM = 8

The Least common denominator of the fraction numbers 3/4 and 3/8 is 9/24

The least common denominator (LCD) of 3/4 and 3/8 is the smallest number that both 4 and 8 can divide into evenly.

The prime factorization of 4 is 2 x 2, and the prime factorization of 8 is 2 x 2 x 2.

Next, we list the prime factors of each denominator and identify any factors that are common to both:

4: 2 x 2

8: 2 x 2 x 2

The common factors are 2 x 2, which means that we only need to include one set of these factors in the LCD.

So, the LCD of 3/4 and 3/8 is:

LCD = 2 x 2 x 2 x 3 = 24

For 3/4, we need to multiply both the numerator and denominator by 6 to get:

3/4 = (3 x 6)/(4 x 6) = 18/24

For 3/8, we need to multiply both the numerator and denominator by 3 to get:

3/8 = (3 x 3)/(8 x 3) = 9/24
