Use elimination using multiplication to solve 2x-y=-1 3x-2y=1

Mathematics
1 answer:
saw5 [17]3 years ago
5 0

Answer:

x = -3 and y = -5

Step-by-step explanation:

2x - y = -1  ⇒  y = 2x + 1

Substitute this into  3x - 2y = 1 to solve for x:

3x - 2(2x + 1 ) = 1  ⇒  3x - 4x - 2 = 1  ⇒  -x = 3  ⇒  x = -3

Now sub the value you found for x into y = 2x + 1 to find y:

y = 2(-3) + 1 = -5

So x = -3 and y = -5

I have a rectangle with a length of 7 cm and a perimeter of 38 cm. Find the area of the rectangle?
Alex17521 [72]

Answer:

area is 84

Step-by-step explanation:

perimeter is 38(p)

length (l) is 7cm

width is?(w)

p=2(l+w)

38=2(7+w)

38=14+2w

2w=38-14

2w=24

w=12

area=l*w

12*7

=84

C. Find the value of x. Round to the nearest<br> tenth.
Otrada [13]
Label your sides= hypotenuse(h),opposite(o),adjacent(a)
hypotenuse=longest(opposite the right angle)
opposite= opposite the other angle
adjacent= the other side
see which sides are involved
in this case it is adjacent and hypotenuse
so A and H
we have to use the SOHCAHTOA rule
Sin=o/h Cos=a/h Tan=o/a
we use cos because a and h are involved
Cos(15°)=62/x
rearrange the equation to find x
x= 62/cos(15)
put this in your calculator
x= 64.12
