Answer:
80.5
Step-by-step explanation:
Given that after a discount of 40% a furniture was bought for $438. The original price of the furniture will be calculated as follows:
discount=40%
new percentage price=100-40=60%
Original percentage price=100%
New buying price=$438
therefore, the original price was:
100/60×438
=$730
The original price was $730
Answer:
Solution given:
<u>A.coordinate are</u>
A(-2,3)
B(0,-3)
C(4,5)
<u>B</u><u>.</u><u>Each</u><u> </u><u>length</u><u> </u><u>are</u><u> </u><u>:</u>
we have
length 
now
AB:
=
units
BC:
=
units
AC:
=
units
<u>C.</u><u> the </u><u>figure</u><u>:</u>
<u>By</u><u> </u><u>using</u><u> </u><u>Pythagoras</u><u> </u><u>law</u>
base[b]=AB=perpendicular [p]=AC
hypotenuse [h]=BC
we have
h²=p²+b²
substituting value
(
)²=2p²
16*5=2*(
)²
80=2*4*10
80=80
<u>SO</u><u> </u><u>IT</u><u> </u><u>IS</u><u> </u><u>RIGHT</u><u> </u><u>ANGLED</u><u> </u><u>ISOSCELES</u><u> </u><u>TRIANGLE</u><u>.</u>
Answer:
3
Step-by-step explanation:
(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)

![= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B10-%5B-2%5D%7D%7B3-%5B-1%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B10%2B2%7D%7B3%2B1%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B4%7D%5C%5C%5C%5C%3D4)
m = 4
y - y₁ = m (x - x₁)
y - [-2] = 4(x - [-1])
y + 2 = 4(x + 1)
y + 2 = 4x + 4
y = 4x + 4 - 2
y = 4x + 2
