Answer:

The price before increase = 1255.5

Step-by-step explanation:

7% of 1350 = \frac{7*1350}{100}

= 94.5

The price before increase = 1350 - 94.5

The price before increase = 1255.5

Inputs:

Original Price: $1350.00

Discount Percentage: 7%

Results:

Discount: $94.50

Final Price: <u>$1255.50</u>

So since 7% off of $1350.00 is $1255.50, you're saving $94.50.

Hope I helped.

Parallel to y = 4x - 6 <br> through (6,-3)
kolbaska11 [484]

Answer:

y=4x-27

Step-by-step explanation:

Parallel lines have the same slope, so lets use 4 as the slope.

Plug in the slope, and the two points into point-slope form to find the y-intercept:

<u>y+3=4(x-6)</u>

1) Distribute the 4 to x and -6:

y+3=4x-24

2) Subtract 3 from both sides:

y=4x-27

What is the range of the function y=-x² +1?<br> A) y≤ -1<br> B) y²-1<br> C) y≤ 1<br> D) y≥ 1
MakcuM [25]

Answer:

Option (C)

Step-by-step explanation:

The minimum value of x² is 0, and the maximum value is unbounded, so therefore, the maximum value of -x² is 0, and the minimum value is unbounded.

So, this means that adding 1 to this, the range matches with option C.

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle?
zvonat [6]

Answer:

It is C.

Step-by-step explanation:

The centre of the circle is at the midpoint of The diameter = (8+2)/2, (6+0)/2 = (5,3) so the left side of the equation is (x-5)^2+(Y-3)^2. Now we need to work out the radius:

The diameter = square root(8-2)^2+6^2) = square root of 72 = 6sqrt2.

So the radius = 3sqrt2 and r^2=18.
