help pleaseeeeeeeeeee

Answer:

x = -2

Step-by-step explanation:

Hi!

Your answers should be : 1. Obtuse | 2. Acute | 3. Obtuse

Here's a little tip for you to remember if you cant get an answer off of brainly: if its 90ft (or degrees or what ever you want to call it) then its right, if its over 90ft its Obtuse, and if its under 90ft its Acute.

Hope this helps!

Let me know if you need anymore help!

Yours truly,

Answer: 45 students

Step-by-step explanation:

Company A’s charge can be represented by: 4s+60

Company B’s charge can be represented by: 2s+150

s is the charge per student

To find the cost at which they are the same, I will set both equations equal to each other.

4s+60=2s+150

-2s -2s

2s+60=150

-60 -60

2s=90 Divide both sides by 2

s=45

So when 45 students are going, the cost for both companies are the same.

Answer:

The coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3)

Step-by-step explanation:

The slope of the given line AB can be presented as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m =\dfrac{-5-4}{2-(-1)} = \dfrac{-9}{3} =-3[/tex]

The slope of a perpendicular line  to a given line is equal to the negative reciprocal of the slope of the given line

Therefore, the slope of the perpendicular to a line that has a slope of m is -1/m

The slope of the perpendicular to the line AB is therefore [tex]-\dfrac{1}{3}[/tex]

From which we get the equation of the perpendicular to the line AB given as follows;

y - 4 = -1/3 × (x - 3)

y - 4 = -x/3 + 1

y = -x/3 + 1 + 4

y = -x/3 + 5

When x = 6, y = -6/3 + 5 = 3

Therefore, the coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3).

Using the slope concept, it is found that the coordinate pair is:

[tex]D\left(x, \frac{x}{3}+9\right)[/tex]

The slope of a coordinate pair [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the change in y divided by the change in x, that is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

If two segments are perpendicular, the multiplication of their slopes is -1.

For segment AB, the slope is:

[tex]m = \frac{-5 - 4}{2 - (-1)} = -\frac{9}{3} = -3[/tex]

At segment CD, we want that:

[tex]-3m = -1[/tex]

[tex]m = \frac{1}{3}[/tex]

Considering D(x,y), we have that:

[tex]\frac{y - 4}{x - 3} = \frac{1}{3}[/tex]

Writing y as a function of x:

[tex]x - 3 = 3(y - 4)[/tex]

[tex]3y - 12 = x - 3[/tex]

[tex]3y = x + 9[/tex]

[tex]y = \frac{x}{3} + 9[/tex]

Thus, the coordinate pair is:

[tex]D\left(x, \frac{x}{3}+9\right)[/tex]

Answer:

x = -6

Step-by-step explanation:

Distribute the 2 into the brackets:

2x + 10 = -2

leave the 2x alone on one side:

2x = -2 -10

2x = -12

divide both sides by 2:

x = -6

Answer:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 385 by 6 and keep only what is to the left of the decimal point:

385 / 6 = 64.1667 = 64

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

385 - (6 x 64) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 385/6 as a mixed number is:

64 1

Answer:

x=160°, y= 62°

Hope this helps

Answer:

∠X = 160°, ∠Y = 62°

Step-by-step explanation:

∠ABD = ∠FDC = 20° [ DF║AB ]

∠X = 180° - ∠FDC

∠X = 180° - 20° = 160°

∠FCD = ∠BCA = 98°        

∠Y = ∠CAB [ DF║AB]

∠BCA+∠CAB+∠ABC = 180°

98°+∠CAB+20° = 180°

∠CAB = 180° - 118° = 62° = ∠Y
