Answer:5 sqrt(2)
Step-by-step explanation:
All the sides of the square are congruent by the markings. Therefore they all measure 5 and because all 4 sides are congruent it is a square. Because it is a square the corners are right angles and you can use the Pythagorean Theorem. a^2 +b^2 = c^2.
5^2 + 5^2 = x^2
25 + 25 = x^2
50= x^2
X = square root of 50
X= square root of 25 Times Square root of 2
X= 5square root of 2
Answer:
$1095.6.
Step-by-step explanation:
A 12% discount (12% off) means that the customer will save 12% of the full price. The full price here is equal to $1,245. The customer will thus save
.
The actual price paid will thus equal
.
Answer:
y = -7/2x +17
Step-by-step explanation:
First, lets put the original equation into slope intercept form which is y=mx+b
7x + 2y = -8
subtract 7x on both sides
2y = -7x -8
divide by 2 on both sides
y = -7/2x - 8/2
y = -7/2x - 4
now we can plus in any x and y values to get a new b, which is our y intercept.
lets use (4,3)
Also, since they are parallel, their slope (m) will be the same.
y = -7/2x + b
3 = -7/2(4) + b
3 = -14 + b
b = 17
lets plug in our new b into our original equation
y = -7/2x + 17
