Which is the slope for the equation that is perpendicular to y=-4x+3

zzz [600]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

The equation for a line is y=mx + b where m represents the slope

If a line is perpendicular to another line, it's slope is the negative reciprocal of the other line's slope.

The reciprocal of -4 is $-\frac{1}{4}$

And the negative of that would be $\frac{1}{4}$

A sofa regularly rells for $800. The sale price is $600

sveta [45]

Because the sofa usually sells for $800, we know that's 100% of the price.

100% = $800

Let's find 1%.

1% = $800/100

1% = $8

Next, multiply $8 by 75 to find the percent of the sofas price when it's $600.

75% = $600

We now know that $600 is 75% of the sofas original price.

100% - 75% = 25%

The percent of decrease I'm the sofas sale price is 25%.

Hope I got that right, the question was worded a little strangley so I wasn't quite sure what you were asking :)

Answer:

see below

Step-by-step explanation:

(x) = 7 - 2x

Let t(x) =0

0 = 7-2x

Subtract 7 from each side

-7 = -2x

Divide by -2

-7/-2 =-2x/-2

7/2 =x

h(x) = 4x + 2

Replace x with x+3

h(x+3) = 4(x+3) + 2

Distribute

= 4x+12 +2

=4x+14

a trapezoid with base measure of 23 km and 29km an area of 390km . find the height of the trapezoid.

cupoosta [38]

Hello!

To find the area of a trapezoid you use the equation

$A = \frac{a+b}{2} h$

Put in the values you know

$390 = \frac{23+29}{2} h$

Add

$390 = \frac{52}{2} h$

Divide

$390 = 26 * h$

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!
