Answer:
1. x = -4y ---> y = (-1/4)x
slope = -1/4. y-intercept = (0,0)
2. y = -2x + 4
3. y = (1/3)x - 1
Step-by-step explanation:
1. Re-write your equation so that x is on the right and y is on the left:
x = -4y ---> y = (-1/4)x
slope = -1/4. y-intercept = (0,0)
2. y-intercept = (0,4) ----> P1
x-intercrpt = (2,0) ----> P2
slope m = (y2 - y1) / (x2 - x1)
= (0 - 4)/(2 - 0)
= -2
therefore, y - y1 = mx - x1 ---> y - 4 = -2x
or y = -2x + 4
3. y-intercept = (0,-1)
x-intercept = (3,0)
m = (0 - (-1)) / (3 -0) = 1/3
y - (-1) = (1/3)x - 0 ---> y = (1/3)x - 1
A^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 + 81 = 324
a^2 = 243
a = 15.589 = 15.6 feet is the angle the ladder is at :)
Answer:
tell ur teacher am not sure about the question
The value of the expression is one eight
<h3>How to solve the expression?</h3>
The expression is given as:
negative one fifth times the quantity 4 minus 14 times the quantity one fourth squared end quantity
Rewrite properly as:
-1/5 * (4 - 14) * (1/4)^2
Evaluate the difference
-1/5 * (-10) * (1/4)^2
Evaluate the exponent
-1/5 * (-10) * 1/16
This gives
2 * 1/16
Further, evaluate
1/8
Hence, the value of the expression is one eight
