−4x+18>2x+12
−4x​+18−18>2x+12−18
−​4x−2x>2x−6−2x

−​6x>−6
Multiply both sides by −1 and reverse the inequality
(​−6x)(−1)<(−6)(−1)
6x<6
x<1
In interval notation (-∞, 1)

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
loris [4]

Answer:

New\ Lengths = (14,21)

New\ Scale\ Factor = \frac{1}{7}

Step-by-step explanation:

Given

Rectangle:

Length = 2 in

Width = 3 in

Scale Factor = 7

Solving (a):

The side lengths of the new scale is calculated as follows;

New Lengths = Old Lengths * Scale Factor

New\ Lengths = (2,3) * 7

New\ Lengths = (2 * 7,3* 7)

New\ Lengths = (14,21)

Solving (b): To go back to the original length

Given that the initial scale factor is 7;

The new scale factor is the reciprocal of the old factor;

Hence;

New\ Scale\ Factor = \frac{1}{7}

How do you write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1,1)
harkovskaia [24]
First you have to put it into point-slope form before you can write it in slope-intercept form which is y-y1=m(x-x1)

Y-1=2(x-1)
Distribute the 2 to the x and -1
Y-1=2x-2
Move it all to one side
Y=2x-1
