By visually assessing we can eliminate the other choices until we have the ff:

(–1, –1), (0, 0), (1, 1), (2, 8)(–1, 1), (0, 0), (1, 1), (2, 4)<span>
Well, it's definitely not the second set of points. Exponential functions are monotonic (either always increasing, or decreasing). In the second set, the function has decreased from (-1,1) to (0,0), and then increased from (0,0) to (1,1).</span>

Write an equation for the line parallel to the given line that contains C<br> C(2,6); y= -4x + 7

MrRa [10]

Answer:

$y=-4x+14$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

$y=-4x+7$

This is the equation of the given line in slope intercept form

The slope is $m=-4$

step 2

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are the same

therefore

The slope of the line parallel to to the given line is $m=-4$

step 3

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=-4$

$C\ (2,6)$

substitute

$y-6=-4(x-2)$

step 4

Convert to slope intercept form

$y-6=-4(x-2)$

isolate the variable y

$y-6=-4x+8$

$y=-4x+8+6$

$y=-4x+14$

A rectangle is enlarged by a factor of 1.5. The width is given as w=2 and the length is given as l =7 in. What would be the peri

guapka [62]

Answer:

Hence Perimeter for new rectangle will be 27 units .

Step-by-step explanation:

Given:

A rectangle with enlarged factor of 1.5

L=7 and W=2

To Find:

Perimeter for new rectangle

Solution:

First calculate the new dimensions for new rectangle ,

Given that original length and width as 7 and 2 respectively and it is increasing by 1.5 times of the original ones

So

New length =1.5 *L

=1.5 *7

=10.5 units

And for width,

New width=1.5 *W

=1.5 *2

=3

Hence New dimensions are 10.5 and 3 units .

So perimeter of new rectangle =2(New length + New breadth)

=2(10.5+3)

=2(13.5)

=27 units

What is the value of x? <br><br> Enter your answer in the box.<br><br> x =___

Zanzabum

Answer:

x = 12

Step-by-step explanation:

The diagram shows an equilateral triangle (because all angles are congruent). All sides in equilateral triangle are congruent, so

$4x-10=5x-22=3x+2$

Solve the equation

$4x-10=5x-22\\ \\4x-10-4x=5x-22-4x\\ \\-10=x-22\\ \\-10+22=x-22+22\\ \\12=x$

Check this value:

$4x-10=4\cdot 12-10=48-10=38\ units \\ \\5x-22=5\cdot 12-22=60-22=38\ units\\ \\3x+2=3\cdot 12+2=36+2=38\ units$

Thus, $x=12$
