jarptica [38.1K]

Problem

evaluate the function

f(-x) = f(x)

plug in the points (2,1) then solve

Solution

For this case we can conclude that:

f(2) =1

So then we satisfy that:

f(-2) =1

If CX = 5 units, then DZ = ___ units

gulaghasi [49]

Answer:

$DZ=4\ units$

Step-by-step explanation:

we know that

If CD is parallel to XZ

then

Triangle XYZ is similar to Triangle YCD

therefore

The ratio of their corresponding sides are equal

$\frac{XY}{CY}=\frac{ZY}{YD}$

we have

CX=5\ units, CY=25\ units, YD=20\ units,

$XY=CX+CY$

$XY=5+25=30\ units$

$ZY=YD+DZ$

$ZY=20+DZ$

substitute the values

$\frac{30}{25}=\frac{20+DZ}{20}$

$20\frac{30}{25}={20+DZ}$

$24={20+DZ}$

$DZ=4\ units$

Write an equation of a line that goes through the point (-9, 3), and is perpendicular to the line 3x + y = 5

Vlad [161]

To find the slope of the line, first find the slope of 3x + y = 5, and then its opposite reciprocal.

3x + y = 5
y = -3x + 5
the slope of 3x + y = 5 is -3.

the slope is -3, so the opposite reciprocal slope is 1/3.

the equation of any line is y = ax + b
to find this line, y = 3, x = -9, and the slope is 1/3.

3 = -9a + b
3 = -9 (1/3) + b
3 = -3 +b
b = 6

substitute a and b into the equation
y = ax + b
y = 1/3x + 6

the equation of the line is y = 1/3x + 6.

A store manager predicts that 150 blankets will be sold if each blanket

Sever21 [200]

Answer:

$47

Step-by-step explanation:

Given: Store manager have predicted that 150 blanket can be sold at $32 each.

Also he has predicted sales of 2 blanket will decrease with $1 increase in price.

Now, finding price at which 120 blanket can be sold.

As we know cost of 150 blanket is $32 and we are finding for 120 blanket, which mean we have to increase price to decrease sales.

∴ $150-120 = 30\ blankets$

Using unitary method to find correct price.

For 2 decrease in sales = $1 increase in price

∴ 30 decrease in sales of blanket = $15 increase in price

Next, price of 120 blanket = $Price of 150\ blanket + increase\ in\ price$

Price\ of\ 120\ blanket = $32+15 = \$ 47$

∴ $47 should be the price for at least 120 blanket to be sold.
