X-y=5
xy=3.36
add y to both sides on first
x=5+y
sub that in other eqation
(5+y)y=3.36
expand
y^2+5y=3.36
minus 3.36 both sides
y^2+5y-3.36=0
use quadratic formula
for
ay^2+by+c=0

for 1y^2+5y-3.36




y=-2.5+/-3.1
y=5.6 or 0.6
sub back
x=y+5
so
x=10.6 or 5.6
the numbers are either 10.6 and 5.6 or 0.6 and 5.6
wait,but 10.6 and 5.6 don't multiply to get 3.36 so that is an extrainiesous answer
answer is 0.6 and 5.6
Acute means that has 3 angles less than 90 degrees
obtuse means at lesat 1 angle is more than 90 degrees
right triangle means 1 angle=90 degrees
s we solve for thierd angle
all angles add to 180 so
35+45+x=180
80+x=180
subtract 80
x=100
100>90
obtuse angle is answer
The value is 21 Because three represents those to variables which both equal to 21.
Answer:
-7 < x
Name 2 values
0 and 10
Any number greater than -7 will work
Step-by-step explanation:
-4 < 2(x + 5)
Divide each side by 2
-4/2 < 2/2(x + 5)
-2 < (x + 5)
Subtract 5 from each side
-2-5 < x+5-5
-7 < x
Name 2 values
0 and 10
Any number greater than -7 will work
Answer:
<u>Given is the piecewise function</u>
<h3>The first interval</h3>
<u>Domain:</u>
<u>The function</u>
<h3>The second interval</h3>
<u>Domain</u>
<u>The function</u>
- The slope is m = (0 - (-4))/(0 - (-2)) = 4/2 = 2
- The y-intercept is 0
- y = 2x
<h3>The third interval</h3>
<u>Domain</u>
<u>The function</u>
- The slope is m = (0 - 2)/(4 - 0) = - 1/2
- The y-intercept is 2
- y = -1/2x + 2
