The slope of parallel line m = -7 is an integer

Step-by-step explanation:

Explanation:-

Given that the parallel line

                     -7x-y = 2

we know that the slope of the two parallel lines are equal

m₁ = m₂

The given parallel line equation

                           - 7 x - y = 2

The slope-intercept form

                             y = - 7x -2

comparing

                             y = mx +C

slope of parallel line m = -7 is an integer

y- Intercept  c = -2

Answer:

(√2 - √6) / 4

C. square root of two minus square root of six divided by four.

Step-by-step explanation:

sine of negative eleven pi divided by twelve.

We have :

sin(-11π/12)

sin((4 - 15)π / 12) = sin(4π/12 - 15π/12)

sin(4π/12 - 15π/12) = sin(π/3 - 5π/4)

Recall:

Angle difference formula:

sin(A - B) = sinAcosB - sinBcosA

Hence,

sin(π/3 - 5π/4) = sin(π/3) cos(5π/4) − sin(5π/4) cos(π/3)

From trigonometry:

sinπ/3 = √3/2

cos5π/4 = -√2/2

sin5π/4 = -√2/2

cos π/3 = 1/2

(√3/2) (-√2/2) − (-√2/2) (1/2)

-√6/4 - -√2/4

-√6/4 + √2/4

√2/4 - √6/4

(√2 - √6) / 4

(7, 10)

Step-by-step explanation:

The vector has an x component of 5 and a y component of 7, so we can add each of these components to the coordinates of B to get its image:

B(2,3)

B'(2 + 5, 3 + 7) = B'(7, 10)

The image will be located at (7, 10).

Vectors, in Maths, exist as objects which have both, magnitude and direction. Magnitude determines the size of the vector. It exists described by a line with an arrow, where the length of the line exists the magnitude of the vector and the arrow displays the direction.

The vector has an x component of 5 and a y component of 7, so we can add each of these components to the coordinates of B to get its image:

B(2,3)

B'(2 + 5, 3 + 7) = B'(7, 10)

Answer:

The perimeter of ΔABC is 43 units

Step-by-step explanation:

An illustrative diagram is shown in the attachment below.

To find the perimeter of the triangle, we will first determine the length of the unknown sides.

First, we can determine /BC/ using the Sine rule

From Sine rule

[tex]\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}[/tex]

∴ [tex]\frac{SinA}{a} = \frac{SinC}{c}[/tex]

In the diagram, [tex]a = /BC/[/tex] and [tex]c = /AB/ = 12[/tex]

m∠A=60° and m∠C=45°

∴ [tex]\frac{Sin60}{/BC/} = \frac{Sin45}{12}[/tex]

[tex]/BC/ = \frac{12 \times Sin60}{Sin45}[/tex]

[tex]/BC/ = 6\sqrt{6}[/tex]

To find /AC/, will first determine m∠B

m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)

60° +m∠B + 45° = 180°

m∠B + 105° = 180°

m∠B = 180° - 105°

m∠B = 75°

Also, using the sine rule

[tex]\frac{SinB}{b} = \frac{SinC}{c}[/tex]

From the diagram, [tex]b = /AC/[/tex]

[tex]\frac{Sin75}{/AC/} = \frac{Sin45}{12}[/tex]

[tex]/AC/ = \frac{12 \times Sin75}{Sin45}[/tex]

[tex]/AC/ = 6 + 6\sqrt{3}[/tex]

Now,

The perimeter of ΔABC = /AB/ + /BC/ + /AC/

= [tex]12 + 6\sqrt{6} + 6+6\sqrt{3}[/tex]

= 43.09 units

≅ 43 units

Hence, the perimeter of ΔABC is 43 units.

Answer:

Using the figure above, if AB = RT and ∠R = 70°, then ________.

ΔABC ~ ΔRTS

m ∠ S = 50°

ΔABC ≅ ΔRTS

m ∠ S = 60°

Answer:

3. Yes, because 160 / 4 = 40 and 120 / 3 = 40.

4. 10, because 24 / 12 = 2 and 20 / 2 = 10

Answer:

3. David and Aryana use their phones at the same rate.

4.10 parts of water to 20 parts of cornstarch.

Step-by-step explanation:

3. First, you have Aryana who uses 160 mins in 4 days. Then there is David who has 120 minutes in 3 days. You want to divide the minutes by days to see  how many minutes per day they use their phone. 160/4=40 120/3=40. David and Aryana use their phones at the same rate.

4. First, you have 24c to 12w (c is cornstarch and w is water). If you want to find 20c and what w is, you need to make c into a smaller number. What I mean is that you need to divide the equation as low as it can go, this one happening to be 12. So you do 24 to 12/12 = 2c to 1w. You then multiply the number back up to twenty. so 2*10 = 20 1*10=10. Your final answer is 10 parts of water to 20 parts of cornstarch.

This answer is C, it is on the perpendicular bisector of segment LC.

Draw any line segment P and L, then another point C anywhere, but the length needs to be the same as PL.  You will note that LC (if you connect those points) will become the perpendicular bisector to point P.
