Answer:

y=4/5x-18/5

Step-by-step explanation:

there are multiple ways we can find the slope, let's use two points and the point slope form y=mx+b for this equation. we can find the slope by using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

in this case, we can use the two points (-3,-6), (2,-2)

y2=-2, y1=-6, x2=2, x1=-3

so, the equation is [tex]\frac{-2-(-6)}{2-(-3)}[/tex]

this reduces to 4/5

our slope is 4/5, so the equation for now is y=4/5x+b

let's use (2,-2) to find b. the y is -2, x is 2

-2=4/5(2)+b

-2=8/5+b, multiply both sides by 5:

-10=8+5b, subtract 8 from both sides

-18=5b, divide by 5

-18/5=b

our final equation is y=4/5x-18/5

Answer:

|6-8|=2

Step-by-step explanation:

You see, absolute value makes any number positive. It doesn't matter if the number was already positive or negative. |x|>=0. If that makes sense. So, 6-8 would be -2. But -2 in absolute value would be 2.

Answer:

-7/12

Step-by-step explanation:

Answer:

-7/12

Step-by-step explanation:

-1/3 - 1/4 becomes -4/12 - 3/12

this is because 12 is the common denominator for both fractions. then subtract the numerators because when you add or subtract fractions, the denominator stays the same.

-4 - 3 = -7

the answer is

-7/12

the answer cannot be simplified so it remains the same

Answer: 18ft

Step-by-step explanation: I took the quiz and got 100%

The height of the tree is 8.3 ft.

To solve this problem, we have to find the angle of elevation from the student.

To do this, we have to assume or bring out a right angle triangle and solve for the.

Given that we have the distance of A to F and the point  to F

Using trigonometric ratio,

We can find the tangent of this angle

[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]

The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees

[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]

Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be

[tex]15 - 5 = 10ft[/tex]

Let's use the tangent of the angle to find the height of the tree.

[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]

From the calculations above, the height of the tree is 8.3 ft.

Answer:

50 km an hour

Step-by-step explanation:

if the person is traveling 100 km an hour, we can divide the distance by the time, to find out how fast they were traveling

100 divided by 2 = 50

the person was traveling 50 km an hour

Step-by-step explanation:

[tex]y = 4x - 4 \\ x + y = 11 \\ x + 4x - 4 = 11 \\ 5x = 15 \\ x = 3 \\ y = 4 \times 3 - 4 \\ y = 8[/tex]

Answer

The answer is negative 14.

Step-by-step explanation:

When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

Answer:

I think it is B

Step-by-step explanation:

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

Work Shown:

The smaller angles UVN and NVW add up to the largest angle UVW.

This is due to the angle addition postulate.

(angle UVN) + (angle NVW) = angle UVW

(6x+13) + (46) = 11+10x

6x + 59 = 11 + 10x

6x - 10x = 11 - 59

-4x = -48

x = -48/(-4)

x = 12

----------------

Extra info:

If you're curious about the angles, then we use that x value to find them

Note how 85+46 = 131 to show that (angle UVN) + (angle NVW) = angle UVW is a true equation. This confirms our answer for x.

Solve for X

Add 3.5 to both sides

[tex]X - 3.5 +3.5 = 9.1 + 3.5[/tex]

[tex]X = 9.1 + 3.5[/tex]

Answer:

The coordinates of the point P  in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:

Step-by-step explanation:

Let P be the point.

As the point P is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6

i.e.

(x₁, y₁) = (-2,-8)

(x₂, y₂) = (5,-1)

Rise = y₂ - y₁ = -1 - (-8) = -1 + 8 = 7

Run = x₂ - x₁ = 5 - (-2) = 5 + 2 = 7

1 : 6 ratio means the point P lies at

[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]

Thus,

rise for P = 7 × 14% = 1

run for P =  7 × 14% = 1

Thus, coordinates of P will be:

x = -2 + 1 = -1

y = -8 + 1 = -7

Thus,

The coordinates of the point P  in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:

Step-by-step explanation:

for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse

a² + b² = c²

in this problem, 4² + 10² ≠ 11²

16 + 100 ≠ 121

Answer:

The area of the triangle is 24 inches.

Step-by-step explanation:

First you multiply 8 by 6.

8 * 6 = 48

Next you divide by 2 because a triangle is half of a square.

48 ÷ 2 = 24

So, the answer is 24.

Hope this helps! :)

The area of triangle with base 6 inches and height 8 inches is 24in² .

Given, Right angled triangle .

Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]

Here,

b = base of triangle

h = height of triangle

Substitute the values,

Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]

[tex]= \frac{1}{2} \times 6 \times 8\\ = 3 \times 8\\= 24in^2[/tex]
