Answer:
1, (-5)(8)=-40 2, (4)(-4)=-16. 3, (-1)(-9)=9. 4 , (5)(6)=30. 5, (12)(-2)=-24. 6, (‐15)(9) =-135. 7. (5)(‐6)= -30. 8. 6(‐6) = -36. 9. (‐27)(14) = - 378. 10.(‐32)(0) = 0. 11.(128)(‐3)= -384. 12.(‐54)(‐4) = 216. 13.(+21) ÷ (+7)= +3
Step-by-step explanation:
positive number multiplied by positive number gives positive number
negative number (-ve) times positive number (+ve) gives -ve
-ve times -ve gives +ve
+ve times -ve gives -ve

Y = x^2 . . . (1)
y = -x + 2 . . . (2)
Putting (1) into (2) gives,
x^2 = -x + 2
x^2 + x - 2 = 0
x^2 - x + 2x - 2 = 0
x(x - 1) + 2(x - 1) = 0
(x + 2)(x - 1) = 0
x = -2 or x = 1
y = (-2)^2 or y = (1)^2
y = 4 or y = 1
Solution is (-2, 4) and (1, 1)
Answer:
c=1/8
Step-by-step explanation:
2c-1/4=0
2c=1/4
2c/2=1/4/2
c=1/4x1/2
c=1/8
The required equation of line B is 2y+5x=-2
The equation of a line in point-slope form is expressed as:
y-y0 = m(x-x0)
m is the slope of the line
(x0, y0) is the point on the line
Given the line A expressed as:
2x = 5y – 25
Rewrite in standard form
5y = 2x + 25
y = 2/5 x + 5
The slope will be 2/5
The slope of the perpendicular line will be;

Substitute the point (-6, 14) and slope -5/2 into the equation above to get the required equation of line B

Hence the required equation of line B is 2y+5x=-2
