A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

Describe in words the translation of X represented by the translation rule T ...?
Digiron [165]
<h3>Answer: B. 4 units to the right, 5 units down</h3>

The vector notation <4, -5> is the same as writing (x,y) \to (x+4, y-5) which in my opinion is more descriptive in saying "4 units to the right, 5 units down"

We shift 4 units to the right because of the x+4. Whatever x is, add 4 to it getting x+4. So for instance x = 10 leads to x+4 = 10+4 = 14.

The y-5 is why we shift 5 units down. Eg: y = 37 leads to y-5 = 37-5 = 32.

Find the value of x for which abcd must be a parallelogram 3x 4x-5
Aliun [14]
Let's first denote the intersection point of diagonals with O. In this parallelogram, we can observe that ΔAOB is congruent to ΔCOD because of AB=CD and the angles ∠BAO and ∠OCD are equal (They are alternate angles). According to the rule of congruency, 3x=4x-5 and x=5

73. Suppose that you want to buy a house that costs $175,000. You can make a 10% down payment, and 1.2% of the house’s value is
Irina-Kira [14]

Answer:

total monthly payment is  $973.03

Step-by-step explanation:

given data

costs = $175,000

down payment = 10%

house value paid = 1.2%

to find out

monthly payment for a 30 year i.e 360 months

solution

we consider here rate of interest for 30 year is 4.25% so monthly interst rate will be \frac{0.0425}{12} = 0.00375

so We have present value Ap = 0.9 ( 175000) = $157500

and the monthly escrow payment is

monthly escrow payment = \frac{1}{12} × 0.012 × 175000

monthly escrow payment = $175

so  monthly payment formula is

monthly payment = \frac{Ap*r}{1-(1+r)^{-n}}   ..................1

here r is rate and n is time period

so

monthly payment = \frac{157500*0.00375}{1-(1+0.00375)^{-360}}

monthly payment  = 798.03

so the payment to the loan is $798.03 each month

and Then the total monthly payment is  = $798.03 + $175

total monthly payment is  $973.03

On the packaging for a triangular sail, the edge measurements for the sail are listed as 7ft x 15ft x 17ft without unfurling the
kirza4 [7]

The law of cosines can be helpful here. The largest angle (C) will be opposite the longest side (c). That law tells us ...

... c² = a² + b² -2ab·cos(C)

Then

... cos(C) = (a² +b² -c²)/(2ab)

We don't actually need the angle. We only need to know the sign of the cosine.

... cos(C) = (7² +15² -17²)/(2·7·15) = -15/210 . . . . negative sign, so C > 90°

The sail has the shape of an obtuse triangle.

_____

A triangle solver app on your calculator, phone, tablet, or computer can give you the result easily.
