The point-slope form:

y-y_1=m(x-x_1)

We have a slope m = 4 and the point (-3, -1). Substitute:

y-(-1)=4(x-(-3))\\\\\boxed{y+1=4(x+3)}\to\boxed{b}

Target sells a pack of iTunes gift cards for $40. Sam's Club sells them for $38.88. What is the percent decrease from Target's p
patriot [66]

We have been given that target sells a pack of iTunes gift cards for $40. Sam's Club sells them for $38.88. We are asked to find the percent decrease from Target's price to Sam's Club's price.

We will use percent decrease formula to solve our given problem.

\text{Decrease percent}=\frac{|\text{Final}-\text{Initial}|}{\text{Initial}}\times 100\%

\text{Decrease percent}=\frac{|38.88-40|}{40}\times 100\%

\text{Decrease percent}=\frac{|-1.12|}{4}\times 10\%

\text{Decrease percent}=\frac{1.12}{4}\times 10\%

\text{Decrease percent}=0.28\times 10

\text{Decrease percent}=2.8\%

Therefore, the percent decrease from Target's price to Sam's Club's price is 2.8%.

Find the area of a parallelogram if a base and corresponding altitude have the indicated lengths. Base 1 1/2 feet, altitude 6 in
Butoxors [25]
Area of a parallelogram = A =base*height

so in this case is just (1½)(6).

first off let's convert the mixed fraction to "improper",

\bf \stackrel{mixed}{1\frac{1}{2}}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}}
\\\\\\
\cfrac{3}{2}\cdot 6\implies \cfrac{18}{2}\implies 9

The diagram represents a dilation with a center at P. If the scale factor of e dilation is K, which statement about the diagram
boyakko [2]

Answer:

C is correct. If the scale factor is greater than 1, the image is an enlargement. The segment UT could be an enlargement of the segment ST.

Step-by-step explanation:

A. If > 1, then the image of could be .  

B. If 0 < < 1, then the image of could be . ( If the scale factor is between 0 and 1, the image is a reduction )

C. If > 1, then the image of could be .

D.If = 2, then the image of is itself.

A is not correct.  If the scale factor is between 0 and 1, the image is a reduction.

B is not correct.  If the scale factor is between 0 and 1, the image is a reduction.

C is correct.  If the scale factor is greater than 1, the image is an enlargement.

D is not correct.  If the scale factor is 1, the figure and the image are congruent.
