Answer:
The equation of line passing through points (1 , 0) is x - 5 y - 1 = 0
Step-by-step explanation:
Given equation of line as
x + 5 y = 30
Now, equation of line in standard form is y = m x + c
where m is the slope
So, x + 5 y = 30
Or, 5 y = - x + 30
Or, y = - x + 6
So, Slope of this line m = -
Again , let the slope of other line passing through point (1 , 0) is M
And Both lines are perpendicular , So , products of line = - 1
i.e m × M = - 1
Or, M = -
Or, M = - 1 × - =
So, equation of line with slope M and points (1, 0) is
y - = M × (x - )
Or, y - ( 0 ) = × ( x - 1 )
Or, y = x - × 1
Or, y = x -
or, y + = x
Or, 5×y + 1 = x
∴ 5 y + 1 = x
I.e x - 5 y - 1 = 0
Hence The equation of line passing through points (1 , 0) is x - 5 y - 1 = 0 Answer
Answer=
Well first we got to convert yards and feet into inches.
21 feet=252 inches
11 yards=396 inches
Alright so now that we have the inches needed we must find the cost for both Emily and Andy’s needed wire.
Emily:
We know how much it would cost for 200 inches, which is 8$.
15 inches adds a .60$ increase, which means that 5 inches is equivalent to .20$. By adding that to .60$ we get .80$ or the amount it would cost for 20 inches. We now know how much it would cost for 40 inches, 1.60$.
8+1.60=9.60 or how much it costs for 240 inches.
If it costs .80$ for 20 inches that means it costs .40$ for 10 inches.
9.60+.40=10
To find how much it costs for 2 inches we divide .40 by 5 which is .08.
10+.08=10.08$
Emily will spend 10.08$ for her needed wire.
Andy:
We know how much it would cost for 300 inches, which is 12$.
We also know how much it costs for 20 inches, which is .80$. So we multiply that by 4 to get how much it would cost for 80 inches.
.80*4=3.20
We then add that to the cost of 300 inches.
12+3.20=15.20
We know how much it would cost for 10 inches, which is .40$.
So we add that to the amount it would cost for 380 inches.
15.20+.40=15.60
Finally we know how much it costs for 2 inches, which is .08$. So we multiply that by 3 to find how much it costs for 6 inches.
.08*3=.24
We then add that to how much it would cost for 390 inches.
15.60+.24=15.84$
Andy will spend 15.84$ for his needed wire.
Answer:
the answer is $58
Step-by-step explanation: don't for to make me brainliest. All you need to do is to subtract $70 from $12.
The answer is 34/ 69 :) stay safe and i hope this helps
