y=−3x+9 slope of this equation is -3 and y-intercept is 9
Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9
y=−x−5 slope of this equation is -1 and y intercept is -5
Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5
The intersection point of these two lines gives you the solution.
The coordinates of point of intersection (7,-12)
Answer:
$23.88
Step-by-step explanation:
Represent the original price by p.
The sale price is (100% - 60%), or 40%, of p:
$9.55 = 0.40p
Dividing both sides by 0.40 results in:
p = $23.88 (rounded up from $23.875).
Answer:
(3,1) +(1,6)
Step-by-step explanation:
first yiu
2(5*4)+2(4*3)+2(3*5)=94 sq.m (Orginial SA)
2(4*5)+2(5*6)+2(6*4)=148 sq.m (Total SA)
148-94=54 (New SA)
