Answer:

a = 8.5t

y = 32.55

Step-by-step explanation:

Solving (9): The equation of the table

We start by calculating the slope (m)

m = \frac{a_2 - a_1}{t_2 - t_1}

Where:

(t_1,a_1) = (15,127.5)

(t_2,a_2) = (16.5,140.25)

m = \frac{140.25 - 127.5}{16.5 - 15}

m = \frac{12.75}{1.5}

m = 8.5

The equation is then calculated using:

a = m(t - t_2) + a_2

So, we have:

a = 8.5(t - 16.5) + 140.25

Open bracket

a = 8.5t - 140.25 + 140.25

a = 8.5t

Solving (10):

4.8y = 156.24

Required

Find x

Divide both sides by 4.8

y = 32.55

(5+2 i)(4-3i) - (5-2yi)(4-3i) in a + bi form, where y is a real number.
ElenaW [278]
<span>(5+2 i)(4-3i) - (5-2yi)(4-3i)

Factorize out (4 -3i)

(4 -3i)( (5 +2i) - (5 -2yi) )

=  </span><span><span>(4 -3i)(5 +2i - 5 + 2yi)</span>

=  </span><span><span>(4 -3i)(5 - 5 + 2i + 2yi)</span>

= (4 -3i)(2i + 2yi)

= (4 - 3i)(2 + 2y)i.    Let's multiply the first two.
</span>
(4 - 3i)(2 + 2y) = 2*(4 -3i) + 2y*(4 - 3i)           
                      =  8 - 6i + 8y - 6yi
                      =  8 + 8y - 6i - 6yi

(4 - 3i)(2 + 2y)i = (8 + 8y - 6i - 6yi)i                Note: i² = -1
                       =  8i  + 8yi - 6i² - 6yi²
                       =  8i  +  8yi - 6(-1) - 6y(-1)  
                       =  8i  +  8yi  + 6 + 6y
                       =  6 + 6y + 8i + 8yi
                       =  (6 + 6y) + (8 + 8y)i    In the form a + bi

Select the equations whose graphs are parallel to the graph of the equation y=23x+5.
iren [92.7K]

Answer:

2x-3y=9    and    4x-6y=30

Step-by-step explanation:

hello :  

note y=(2/3)x+5  no y=23x+5

2/3 is the slope....... all lines parallel to this line has same slope.

1)   2x-3y=9   means : 3y = 2x-9   divide by 3 : y=(2/3)x-3..same slope.

2)  4x-6y=30  means : 6y= 4x-30 divide by 6 : y=(4/6)x -30/6

but 4/6 = 2/3 so : y=(2/3)x-5..same slope.
