4x-8y=24 find the x-intercept and y- intercept on the graph

2 answers:

8 0

The x intercept is the value of x when y=0
the y intercept is the value of y when x=0
when y=0: 4x-0=24 => x=4
when x=0: 0-8y=24 => y=-3
so the x intercept is 4, and the y intercept is -3

4x-8y=24
move variables to the right side and change its sign
4x=24+8y
divide both sides by 4
x=6+2y

4x-8y=24
move variable to the right and change the sign
-8y=24-4x
divide both sides by -8
y=-3+1/2x

Set up a proportion: (1/4)/6 = 32/x
Cross multiplying, we have (1/4)x = 192
x = (4)(192) = 768 miles

5c squared- d squared+3/2c - 4d...c= -1. d= -4

riadik2000 [5.3K]

For this case we have the following expression:

$5c ^ 2-d ^ 2 + \frac {3} {2} c-4d$

We must find the value of the expression when:

$c = -1\\d = -4$

Substituting we have:

$5 (-1) ^ 2 - (- 4) ^ 2 + \frac {3} {2} (- 1) -4 (-4) =\\5 (1) -16- \frac {3} {2} + 16 =\\5-16- \frac {3} {2} + 16 =\\-11- \frac {3} {2} + 16 =\\- \frac {25} {2} + 16 =\\\frac {-25 + 32} {2} =\\\frac {7} {2}$

Finally, the value of the expression is:

$\frac {7} {2}$

ANswer:

$\frac {7} {2}$

Will mark brainliest if correct (surface area question)

I am Lyosha [343]

Answer:

535

Step-by-step explanation:

8 x 7 = 56

15 x 17 = 255 . 255 / 2 = 127.5

15 x 7 = 105

17 x 7 = 119

119 + 105 + 127.5 + 127.5 + 56 = 535
