Answer:

see explanation

Step-by-step explanation:

(a)

The opposite sides of a rectangle are congruent, hence

x + 1 = 5 ( subtract 1 from both sides )

x = 4

Or

x - 1 = 3 ( add 1 to both sides )

x = 4

(b)

The sum of the 3 angles in a triangle = 180°, hence

3y + 2y + y = 180

6y = 180 ( divide both sides by 6 )

y = 30

Write the equation of a line with a slope of -5 that passes through the point (1, -1).
ipn [44]

In this question, we will use slope intercept form that is y=mx +b, where m is the slope and b is the y intercept .

For the given question . x=1, y=-1 and slope , m = -5

We need to substitute these values in slope intercept form and solve for b, that is

-1=-5(1)+b

-1 = -5+b

Adding 5 to both sides

b =4

So we have slope, m =-5 and b=4

THerefore required equation is

y=-5x+4

A system of linear equations includes the line that is created by the equation y = x+ 3, graphed below, and the line through the
ad-work [718]

Answer:

(8,11)

Step-by-step explanation:

1st line

y = x+ 3

We need to find the equation of the other line

We have two points (3, 1) and (4, 3)

Slope

m = (y2-y1)/(x2-x1)

   = ( 3-1)/(4-3)

   = 2/1 = 2

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y =2x+b

Using the point (4,3)

3 = 2(4)+b

3 = 8+b

3-8=b

-5 =b

y = 2x-5

We have 2 lines

y =x+3 and y = 2x-5

Setting them equal to each other

x+3 = 2x-5

Subtract x from each side

x+3-x = 2x-5-x

3 = x-5

Add 5 to each side

3+5 =x-5+5

8=x

Now we can find y

y =x+3

y = 8+3

y=11

bagirrra123 [75]

Mr Chan spent

90\cdot 0.5 = 45

dollars when he bought the shares. If he sells 45 shares at 3.80, he will gain

45\cdot 3.8 = 171

dollars. So, the net profit would be

171-45 = 126
