Answer:
X is your answer bc when coordinates are flipped over the x-axis the y coordinate goes negative
Answer:
Step-by-step explanation:
Given an inequality that relates the height h, in centimeters, of an adult female and the length f, in centimeters, of her femur by the equation
If an adult female measures her femur as 32.25 centimeters, we can determine the possible range of her height by plugging f = 32.25cm into the modelled equation as shown:
If the modulus function is positive then:
If the modulus function is negative then:
multiply through by -1
combining the resulting inequalities, the estimate of the possible range of heights will be
If we assume this is a right triangle
for a right triangle
if it has legs length a and b and hyptonouse c then
a²+b²=c²
given
a leg is 24
hyptonuse =25
the other leg is b
24²+b²=25²
576+b²=625
minus 576 from both sides
b²=49
sqrt both sides
b=7
the other leg is 7 units
Answer:
Step-by-step explanation:
y = -2x + 2/2.....slope = -2, y int = 2/2(or just 1)
y = -2x + 3/2....slope = -2, y int = 3/2
when the equations have the exact same slope, but different y intercepts.....and this one does....then there is no solution because these are parallel lines....they never cross each others path.
An equvilent equation
remember you can do anything to an equation as long asyou do it to both sides
assuming yo have
x+y=1 and
x-3y=9
mulitply both by 2
2x+2y=2
2x-6y=18
those are equvilent
ok, solve initial
x+y=1
x-3y=9
multiply first equation by -1 and add to 2nd equation
-x-y=-1
<u>x-3y=9 +</u>
0x-4y=8
-4y=8
divide both sides by -4
y=-2
sub back
x+y=1
x-2=1
add 2
x=3
x=3
y=-2
(3,-2)
if we test it in other one
2x+2y=2
2(3)+2(-2)=2
6-4=2
2=2
yep
2x-6y=18
2(3)-6(-2)=18
6+12=18
18=18
yep
solution is (3,-2)
