Answer:

One.

Step-by-step explanation:

The reason why is because 12-5 = 7, meaning that your lowest length has to be 7. meaning, that you can only do one triangle.

Answer:

D. None.

Step-by-step explanation:

<em>The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides. The longest side ( 12 ) >= ( 7 plus  5 ) = 12  is too large.</em>

The Polleys want to put in a swimming pool next summer. They need to save $6,000 over 12 months in order to achieve this goal. T
Sauron [17]

Answer:

Therefore Neither option A nor option B will allow them to meet their goal....

Step-by-step explanation:

The Polleys need to save $6,000 over 12 months.

After 7 months they discovered that they have saved $ 3,100 but in actual they have to save $3,500. It means $400 are short. Therefore for the remaining months they must save $6000-$3100 = $2900. They have to save 2900/5 = $580 each month.

According to the Option A The original amount was $500, in 5 months they will save 500*5 =$2500. They need total of $2900, which means $400 are short.

According to the Option B  Increase savings each month by $100 from their original plan makes a total amount of $3000. This amount exceeds their goal.

Therefore Neither option A nor option B will allow them to meet their goal....

Point Q is the center of dilation. Lines segment S U is dilated to form line segment S prime U prime. The length of Q S is 3 .2
tia_tia [17]

Answer:

Option C.

Step-by-step explanation:

It is given that the dilation rule is D_{Q,2.5}. It means the center of dilatation is point Q and scale factor is 2.5.

Scale factor is the ratio of distance from center to the image of a point and distance from center to the corresponding point.

\text{Scale factor}=\dfrac{QU'}{QU}

It is given that QU=4 and scale factor = 2.5.

2.5=\dfrac{QU'}{4}

Multiply both sides by 4.

2.5\times 4=QU'

10=QU'

We know that

UU'=QU'-QU

UU'=10-4

UU'=6

The distance between U' and U is 6 units.

Therefore, the correct option is C.

12x−5y=−20 y=x+4 x=x=x, equals y=y=y, equals
aksik [14]

Answer:

The solution is (0, 4)

Step-by-step explanation:

Please pay attention to the first two equations and drop the last two:

12x−5y=−20 y=x+4 x=x=x, equals y=y=y   should ideally be:

12x−5y=−20

y=x+4

Let's find x.  Substitute x + 4 for y in the first equation, obtaining:

12x - 5(x + 4) = -20

Carrying out the indicated multiplication, we get:

12x - 5x - 20 = -20, or 7x = 0

If x = 0 then y must be 0 + 4, or 4.  

The solution is (0, 4)
