Answer:

A. $1,710

B. Yes, probably.

Step-by-step explanation:

Assuming that a 10% decrease in energy use leads to a 10% decrease in the electric bill:

We'll want to find the value which is 10% less than the original value, i.e., the bill cost which is 90% of the original bill.

90% = 0.9

Since the original bill was $1900, we can just multiply 1900 by 0.9:

1900*0.9=1710

Answer: A bill of $1,710 would equal a 10% decrease.

Since $1,672 is less than that, then they have decreased their energy use by more than 10% which is likely a success.

Answer: Yes, probably.

PLZ HELP!!!! A pair of equations is shown below: y = 6x − 4 y = 5x − 3 Part A: In your own words, explain how you can solve the
Goryan [66]

Answer:

Step-by-step explanation:

y = 6x − 4

y = 5x − 3

A: chose a value for x(input) and get the out put (y) because the equation already in the slope intercept mode:y=mx+b

x                   y=6x-4                  y=5x-3

1                    y=2                        y=2

2                    y=8                        y=7

0                     -4                            -3

slope  :

y=6x-4    slope is 6            y intercept(0,-4)

y=5x-3      slope is 5          y intercept (0,-3)

solution of the pair of equation is  the point of intersection :

6x-4=5x-3

6x-5x=-3+4

x=1   and y=6x-4   ⇒ y=6-4=2

Find the nonpermissible replacement for a in
lisabon 2012 [21]

Answer:

a ≠ 2

Step-by-step explanation:

Given

\frac{a^2}{-3a+6}

The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that a cannot be, that is

- 3a + 6 = 0 ( subtract 6 from both sides )

- 3a = - 6 ( divide both sides by - 3 )

a = 2 ← excluded value

Write an equation in slope intercept form for the line passing through (2, 6) with a slope of -3−3 .
Vikentia [17]

Answer:

y = 9/5x +12/5

Step-by-step explanation:

First find the slope using the two points

(2,6) and (-3,-3)

m = ( y2-y1)/(x2-x1)

   = (-3-6)/(-3-2)

   = -9/-5

   = 9/5

Using the slope intercept form of the line

y = mx+b where m is the slope and b is the y intercept

y = 9/5x +b

Using one of the points and substituting for x and y

6 = 9/5(2) +b

Getting a common denominator

30/5 = 18/5+b

30/5 -18/5 = b

12/5 = b

y = 9/5x +12/5

What is the equation of the quadratic graph with a focus of (-4, 17/8) and a directrix of y=15/8
MrRa [10]
Yay

so
this is going to be
(x-h)^2=4p(y-k)

(h,k) is the vertex
p is the distance from the vertex to the focus and the vertex to directix

half of the distance between directix and focus is p
if the directix is above the focus, p is negative
if the directix is below the focus, p is positive
so

we see
y=15/8 is the directix
focus is above directix (p is positive)
it is 2/8 or 1/4 above it
so
half of 1/4 is 1/8
p=1/8
the vertex is 1/8 below vertex so it is it at (-4,16/8) or (-4,2)
the equation is
(x-(-4))^2=4(1/8)(y-2) or
(x+4)^2=4(1/8)(y-2) is the equation
