You seemed to have gotten the equation wrong, but don't worry I'll help you
===================================================================
First you simplify the equation
4=<span><span><span>(-1)</span><span>(-3)</span></span>+b
(A negative times a negative is a positive)
</span>4 = 3 + b
(Flip the equation)
b + 3 = 4
--------------------------------------
Then you subtract 3 from each side
<span><span>b+3-</span>3</span>=<span>4-3
</span>b = 1 is your answer
===================================================================
y = -1x - 7 is wrong as well
To find the answer just add -4 on each side for y+4=-<span>1<span>(x-3)</span></span>
<span>y+4+-4</span>=-<span>x+3+-4
</span>y = -<span><span>x - </span><span>1 is the answer
</span></span>To graph, plot points on Y-intercept of -1 and place another point at (-2,1)
Answer:
3 foot 3 inches
Step-by-step explanation:
How much deeper the hole should be = intended depth - current depth
Convert feet to inches for easy calculation
1 ft = 12 inch
5 x 12 = 60 inches
1 foot = 12
12 + 9 = 21 inches
60 - 21 = 39 inches
convert inches to feet
39 /12 = 3 feet 3 inches
Answer:
<em>Approximately 43 feet of minimum cable is needed. </em>
Step-by-step explanation:
This problem can be solved using Trigonometry and Pythagorean theorem. Pythagorean theorem applies on right-triangles (<em>which are known to have one 90° angle</em>). The theorem states that the square of the Hypotenuse is obtained by the squared sum of the other two sides of the triangle (i.e the two sides forming the 90° angle - with the hypotenuse side being across it as:
Eqn. (1)
where
is the hypotenuse
is a side
is a side
<u>Now in this case, the utility pole must be perpendicular to the ground and the anchor being parallel to the ground, and a 90° angle formed between them. </u>Conclusively the cable length will be represented by the hypotenuse in a right triangle. So here we have 
and 
. Plugging in Eqn.(1) and solving for we have:
So we conclude that the minimum length of cable needed by Lamont is
≈43 feet (rounded up).
