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
(a^3-2a^2)-(3a^2-4a^3)
(a^3-2a^2)-3a^2+4a^3
5a^3-5a^2
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
