write the equation in slope intercept form for the line that passes through (-2,2) and is parallel to 2x+4y=16
ratelena [41]

Answer:

<h3>Step 1 - Find the gradient of 2x + 4y = 16</h3>

2x + 4y = 16

4y = 16 - 2x

y = 4 - 1/2x

gradient = -1/2

<h3>Step 2 - Find the Equation</h3>

y - y1 = m(x - x1)

m = gradient, (x1, y1) = (-2,2)

y - 2 = -1/2 (x + 2)

y - 2 = -1/2x - 1

y = -1/2x + 1 → ANSWER

Hope it helps!

Part 1
Rule of thumb for month rent: Rent ≤ 28% of monthly gross income

Then,
Month gross income = $62,112/12 = $5,176
Affordable rent = 0.28*5176 = $1,449.28
Rounding to nearest dollar;
Affordable rent = $1,449.
The correct answer is C.

Part 2
Monthly rent = $1240
Security deposit = 80% of rent = 0.8*1240 = $992
Amount to be paid = 1240*2 + 992 = $3472

The correct answer is B.

Which expression represents the sixth term in binomial expansion (2a-3b)^10
AysviL [449]

Therefore the sixth term in the binomial expansion is=-{10}C_5(2a)^{5} (3b)^5

Step-by-step explanation:

Given

(2a -3b)^{10}

=^{10}C_0 (2a)^{10} + ^{10}C_1(2a)^9(-3b)+^{10}C_2(2a)^8(-3b)^2+...............+^{10}C_10(-3b)^{10}

So,

T_{n+1}= ^{10}C_n(2a)^{(10-n)} (-3b)^n

T_6=T_{(5+1)} =^{10}C_5(2a)^{10-5} (-3b)^5

Therefore the sixth term in the binomial expansion is= {10}C_5(2a)^{10-5} (-3b)^5

                                                                                         =-{10}C_5(2a)^{5} (3b)^5
