creativ13 [48]
2 is the slope so the slope perpendicular to that is -1/2 (negative reciprocal)
-5=-1/2(9)  9*-1/2=-4.5 and -4.5 - 0.5 = -5 so the equation for the line is y=-1/2x -0.5

[-1/4/5] × [-7/10+0.95] - [-2/1/4]
const2013 [10]

Answer:

-2.5625

Step-by-step explanation:

<u>1)[-1/4/5] × [-7/10+0.95] - [-2/1/4] turn that into improper fractions</u>

2 1/4=9/4

which is 1 4/5(-7/10+0.95)9/4

<u>2) 1 4/5(-7/10+0.95)= 0.3125</u>

which is 0.3125-9/4

<u>3)Make into decimal form</u>

9/4 equals 2.25

which is 0.3125-2.25

which all equals -2.5625
