Hello,

y = ax + b where a is the slope

We have A(-4 ; 2) and B(8 ; 5)

a =  \frac{yb - ya}{xb - xa}  =  \frac{5 - ( - 4)}{8 - 2}  =  \frac{9}{6}  =  \frac{3 \times 3}{3 \times 2}  =  \frac{3}{2}

→ Slope : 3/2

Avery deposited $1,250 in a new savings account. Determine which amount is closest to the balance of the account at the end of 3
makkiz [27]

Answer:

$1456.25

Step-by-step explanation:

Given data

P= $1,250

t= 3 years

r=5.5%

The compound interest expression is given as

A= P(1+r)^t

substitute

A=  1250(1+0.055*3)

A=  1250(1+ 0.165)

A= 1250(1.165)

A= 1456.25

Hence the amount after 3 years is $1456.25

The solution set of a linear system whose augmented matrix is [a b c d] is the same as the solution set of Ax = d, where A = [a
Charra [1.4K]

Answer:

True

Step-by-step explanation:

First statement

[a b c | d][x]

[a b c]x=d

ax+bx+cx=d

Second statement

Ax=d

Given that A = [a b c]

[a b c]x=d

ax+bx+cx=d

ax+bx+cx=d

Then, they are going to have the same solutions
