<span>y = –2x + 5
–5y = 10x + 20

replace </span>y = –2x + 5  into –5y = 10x + 20

–5( –2x + 5 ) = 10x + 20
10x - 25 = 10x + 20 
        -25 = 20...can't be...

Write an explicit formula for the arithmetic sequence 15.6, 15, 14.4, 13.8,..., and then find the 32nd term.
uysha [10]

Answer: the 32nd term is - 3

Step-by-step explanation:

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + d(n - 1)

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 15.6

d = 15 - 15.6 = 14.4 - 15 = - 0.6

n = 32

The explicit formula for the arithmetic sequence is

Tn = 15.6 - 0.6(n - 1)

We want to determine the value of the 32nd term, T32. Therefore,

T32= 15.6 - 0.6 (32 - 1)

T32 = 15.6 - 18.6

T32 = - 3

Nicole invested her savings in two investment funds. The amount she invested in Fund A was $3000 less than the amount she invest
victus00 [196]
<span>Let us denote the amount of investment in the Fund B with x. We know that Fund B returned 8%  and that in Fund A Nicole invested </span>$3000 less than the amount she invested in Fund B, so we can write: x-3000<span>Fund A returned 6%. 
Interest = 2060
The percent has been converted by multiplying the equation by 100 
8x+6(x-3000)= 2060*100 
8x+6x-18000=206000
</span><span>14x=206000+18000
14x=224000
x=16000
Nicole invested in Fund B $16000 and in Fund A </span><span> $16000-3000=13000.</span><span>

Convert to standard form of the equation into the slope intercept form -3x-5y=-15
Mamont248 [21]
Our goal is to get y by itself
We will first add 3x to both sides to get
-5y = 3x - 15
We will then divide both sides by -5 to get y by itself which becomes
y = -3/5x + 3

Given point P (3, 4). What is the distance of point P from (a) x axis (b) y axis?
vova2212 [387]

Answer:

a) 3

b) 4

Step-by-step explanation:

The point P is(3,4)

which means that 3 is the point P's x- coordinate and 4 is it's y-coordinate

Because we use the axes as our reference point when plotting points,

the distance of P from x-axis and y-axis would be the point itself.
