Answer 1

Answer: -1.56i^ +1.07j^

Step-by-step explanation:Vector C = -1.56i^ +1.07j^

This question requires that we use the properties of the scalar product of two vectors to find the required x and y component.

The dot product of two perpendicular vectors is equal to and the product of two vectors that are not parallel is equal to a nonzero value.

These are the properties that have been used in solving this problem alongside solving the simultaneous questions generator.

HELP ASAP PLS

Answers

Answer:

inconsistent, none

Step-by-step explanation:

Write both equations in slope-intercept form to see if the lines are parallel.

These two lines have slope m = −2 and different y-intercepts, therefore they are parallel.

Since the lines are parallel, the system is inconsistent and there are no solutions.

The system of equations  4x + 2y = −8 6x + 3y = 9 is inconsistent and has no solutions.

What is system of Equations?

A system of equations is a collection of two or more equations with a same set of unknowns.

We need to write both equations in slope-intercept form to see if the lines are parallel.

4x+2y=-8

2y=-8-4x

y=-4-2x,

y=-2x-4, m₁=-2

and 6x+3y=9

3y=9-6x

y=-2x+3, m₂=-2.

So two lines have slope m = −2 and different y-intercepts,

It means two line are parallel.

Since the lines are parallel, the system is inconsistent and there are no solutions.

Hence 4x + 2y = −8 , 6x + 3y = 9 is inconsistent and has no solution.

Graph the linear equation 5x-4y < 20

Answers

using a graphing calculator:

Answer: (See attached image file)

Step-by-step explanation:

Start by plotting given key features

Based on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x  (5x = 20)(x = 20/5 = 4)        (4, 0)  

We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5)      (0, -5)  

Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.

Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.        

Three times a number increased by 44 is the same as the opposite of the number. Find the number

Answers

Answer:

- 11

Step-by-step explanation:

let the number be n then 3 times the number is 3n and the opposite is - n

3n + 44 = - n ( add n to both sides )

4n + 44 = 0 ( subtract 44 from both sides )

4n = - 44 ( divide both sides by 4 )

n = - 11

The required number is - 11

The solution is A. (-2,7) and C. (3,2)

Step-by-step explanation:

x+y = 5 ............(1)

x²+y = 11 ............(2)

_________________________

y = 5-x

x²+(5-x) = 11

x²+5-x-11 = 0

x²-x-6 = 0

x²+2x-3x-6 = 0

(factor statement)

x(x+2)-3(x+2) = 0

(x+2) (x-3) = 0

x+2=0 x-3 =0

x = -2 x = 3

(x1 = -2, x2 = 3)

_________________________

y = 5-x

y = 5-(-2) ............(1)

y = 5-3 ............(2)

Lines l and m are parallel lines cut by transversal n. Angle R is measured by (3x +12)° and angle S is measured by (5x +8)°.
What is the measure of angle s?
A-90°
B-108°
C-72°
D-20*

Answers

Answer:

x = 20

Step-by-step explanation:

Lines l and m are parallel so the sum of given angles is = 180

3x + 12 + 5x + 8 = 180 add like terms

8x + 20 = 180 subtract 20 from both sides

8x = 160 divide both sides by 8

x = 20 replace x with 20 in given expression to calculate any measure.
