Hi!

Step-by-step explanation:

$SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{(-4)-5}{(-1)-2}=\frac{-9}{-3}=3$

Slope is 3.

Hope this helps!

Step 3

EXPLANATION

The given polynomial expression is:

$2 {p}^{2} - 3p - 7 - (3 {p}^{2} + p - 5)$

Fatau correctly expanded the parenthesis in the first step.

$2 {p}^{2} - 3p - 7 - 3 {p}^{2} - p + 5$

Fatau also correctly grouped the like terms to obtain:

$(2- 3) {p}^{2} + (- 3 - 1)p + (- 7 + 5)$

Fatau committed a mistake at the third step.

Instead of obtaining,

$- {p}^{2} - 4p - 2$

He mistakenly got:

${p}^{2} - 2p +2$

Jessica plans to purchase a car in one year at a cost of $30,000. how much should be invested in an account paying 10% compounde

dezoksy [38]

The formula is
A=p (1+r/k)^kt
A fund needed 30000
p Amount invested?
R interest rate 0.1
K compounded semiannual 2
T time 1 year
Solve the formula for p to get
P=A÷(1+r/k)^kt
P=30,000÷(1+0.1÷2)^(2×1)
P=27,210.88

Send it quick guys...

Paladinen [302]

Answer:

194

Step-by-step explanation:

Recall 2 rules to solve this easily:

1. $(a+b)^2=a^2+2ab+b^2$

2. $(a-b)^2=a^2-2ab+b^2$

Now, if we let a = 7 and $b=4\sqrt{3}$ , we can say the problem is basically of the form:

$(a+b)^2 + (a-b)^2$

This can be simplified using the rules:

$(a+b)^2 + (a-b)^2\\a^2+2ab+b^2+a^2-2ab+b^2\\2a^2+2b^2$

Now we can plug the values of a and b we initially thought of (remember though $\sqrt{x} \sqrt{x} =x$ ):

$2a^2+2b^2\\2(7)^2+2(4\sqrt{3})^2\\ 2(49)+2(4\sqrt{3})(4\sqrt{3})\\98+2(4)(4)(\sqrt{3} )(\sqrt{3} )\\98+2(4)(4)(3)\\98+96 \\194$

194 is the final answer.
