First we find the slope of the original equation
4x - 2y = 3
-2y = -4x + 3
y = -4/-2x - 3/2
y = 2x - 3/2......slope here is 2
for a parallel line, we use the same slope
y = mx + b
slope(m) = 2
(2,1)...x = 2 and y = 1
now we sub and find b, the y int
1 = 2(2) + b
1 = 4 + b
1 - 4 = b
-3 = b
so ur parallel equation is : y = 2x - 3
for a perpendicular slope, we need the negative reciprocal. All that means is flip the slope and change the sign. So we have a slope of 2...the negative reciprocal we need is -1/2
y = mx + b
slope(m) = -1/2
(2,1)...x = 2 and y = 1
now we sub again
1 = -1/2(2) + b
1 = -1 + b
1 + 1 = b
2 = b
ur perpendicular line is : y = -1/2x + 2
=========================
x + 4 = 0
x = -4....this is a vertical line with an undefined slope....sorry but I am not sure about this one
147% into a mixed number would equal 1 4/7
147% into a fraction would be 147/100
5.) no cause in the first triangle its sas (side angle side) but not in the second triangle and 6.) yes cause its sas in both triangles
Answer:
- 0.16
Step-by-step explanation:
4x + 5y = -20
I did first is
i minus 5 minus 5 and 5 minus -20
so it will be
4x = -25
then next
4 ÷ 4
4 ÷ -25
x = -0.16
