759.78=(a+33.1)32.4 x 1/2 must multiply both sides by 2 to get rid of 1/2
2(759.78)=(a+33.1)32.4 multiply and distribute each side
1519.56=32.4a+1072.44 subt. 1072.44 from both sides
1519.56-1072.44=32.4a   now subt on the left side
447.12=32.4a  now you can divide by 32.4 on both sides to get a by itself
447.12/32.4=a  divide
13.8yd= a  this should be the length of a

What is the slope of the line that contains the point (-1,8) and (5,-4) answer.com?
pshichka [43]
THE SLOPE IS -2



if we have the coordinates of two points on a line, we can find the slope with this formula:
s =  \frac{y2 - y1}{x2 -x1}  =  \frac{y1 - y2}{x1 - x2}
so the slope is
\frac{8 - ( - 4)}{ - 1 - 5}  =  \frac{12}{ - 6}  =  - 2
the answer is -2



good luck

What must be the value of x so that lines a and b are parallel lines cut by transversal f?
ExtremeBDS [4]

we know that

if the lines a and b are parallel lines cut by transversal f

then

(6x-36)=96 --------> by alternate exterior angles

solve for x

(6x-36)=96\\ 6x=96+36\\6x=132\\x=(132/6)\\x=22\ degrees

therefore

<u>the answer is</u>

the value of x is 22\ degrees

The polynomial p{x) = x4 -2x3 + 3x2 -ax+3a-7 when divided by x+1 leaves the remainder 19. Find the values of a. Also, find the r
Mrrafil [7]

Answer:

a = 5

Remainder when p(x) is divided by x+2 = 62

Step-by-step explanation:

Given:

P(x) = x⁴-2x³+3x²-ax+3a-7

When x+1 divides the polynomial p(x) the ramainder is 19.

Applying remainder theorem,

x = -1

p(-1) = 19

Substitute the x = -1 into the polynomial expression

p(-1) = (-1)⁴-2(-1)³+3(-1)²-a(-1)+3a-7 = 19

1+2+3+a+3a-7 = 19

6-7+4a = 19

4a-1 = 19

4a = 19+1

4a = 20

a = 20/4

a = 5.

Hence, a = 5

p(x) = x⁴-2x³+3x²-5x+8

If p(x) is divided by x+2,

Then the remainder is p(-2)

p(-2) = (-2)⁴-2(-2)³+3(-2)²-5(-2)+8

p(-2) = 16+16+12+10+8

p(-2) = 62

Hence the remaider when p(x) is divided by x+2 is 62
