Answer:

f(x)

Step-by-step explanation:

f(x)=x-1/x+5

y=x-1/x+5

xy+5y=x-1

xy-x=-1-5y

x(y-1)=1-5y

x=-1-5y/y-1

x=-5

PLEASE HELP

Answer:

a) $2 + 3 + 5 + 6 = 16$

b) $8a + b-9$

c) $8a - 28b + 15c$

Step-by-step explanation:

We are given the following in the question:

1. Equivalent expression

$2 + 3 + 5 + 6$

Since all the terms are like terms, we can write,

$2 + 3 + 5 + 6 = 16$

2. Sum of given expression

$(8a - 2b - 4) \text{ and } (3b - 5)\\ (8a - 2b - 4) + (3b -5)\\= 8a -2b -4 + 3b -5\\\text{Collecting the like terms}\\8a + (-2b+3b) + (-4-5)\\= 8a + b-9$

3. Standard form of the expression

$4(2a) + 7(-4b) + (3 \times c \times 5)\\=(8a) + (-28b) + (15c)\\=8a - 28b + 15c$

which is the required standard form of the given expression.

Kyla makes a triangular school pennant. The area of the triangle is 180 square inches. The base of the pennant is z inches long.

kykrilka [37]

We can represent the base as z and the height as 2z+6. We are going to use the formula A=1/2*b*h and solve for z
180=1/2*z*(2z+6)
360=2z^2+6z
0=2z^2+6z-360
0=2(z^2+3z-180)
0=(z+15)(z-12)
So z=-15 and 12 but it must be positive so then the base is equal to 12

When we plug this into 2z+6 we get 30 for the height
2(12)+6=30

Hope this helps
