Evaluate |x + y|, for x = 8 and y = -15.

Answers

Answer 1

Answer: First, we substitute the numbers to the corresponding variables.

|(8) + (-15)|

And we change the plus sign since we’re just basically subtracting.

|8 - 15|

|-7|

Now to do absolute values, we must remember that it will always equal a positive unless there is a negative sign outside of the | |.

So the final answer will be 7.

Divide 7/24 by 35/48 and reduce the quotient to the lowest fraction.A. 4/10
B. 2/5
C. 42/48
D. 245/1152

Answers

the answer is B.2/5
flip 35/48 so it looks like this 48/35 then chance the divide symbol and put the multiply symbol 7*48=336, and 24*35=840. your answer is 336/840 then simply reduce to get 2/5.

The graph of the equation x2 + y2 + 8x − 10y − 40 = 0 is which of the following conic sections?ellipse

hyperbola

parabola

circle

Answers

in form
ax^2+by^2+cx+dy+e=0
to determine the shape
when a=c and b=d, you have a circle

if you do b^2-4ac
if:
1. the result is GREATER than zero: hyperbola
2. result is EQUAL to zero: parabola
3. result is LESS than zero: elipse

x^2+y^2+8x-10y-40
a is not equal c so nt circle
a=1
b=1
c=8
1^2-4(1)(8)
we can see this is less than 0
ellipse

Write the following comparison as a ratio reduced to lowest terms. 85 minutes to 8 hours

Answers

Let us first convert 8 hours to minutes.

1 hour has 60 minutes,

thus, 8 h = 8 x 60 = 480 minutes.

Thus, ratio = 85 : 480

= 3 : 56 (simplest ratio)
