Answer:
Step-by-step explanation:
When multiplying or dividing two negatives, multiply or divide the normal way and make your answer positive. Two negatives make a positive.
Answer:
A.
Step-by-step explanation:
Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.
Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.
Hence the answer is Graph A.
Answer:
There are 3027 chairs
Step-by-step explanation:
There are 2925 chairs in the theater and 102 chairs in the balcony
all together are 3027
Let m = slope = -4/5
P(x,y) = P(5,10)
Slope-intercept form for the equation of a line:
y=mx+c
Plug m= -4/5 into the slope-intercept formula
y = -4/5x + c
Plug P(5,10) into point-slope formula
y = -4/5x + c
10 = -4/5(5) + c
10 = -4 + c
substract -4 from both sides,
10 - (-4) = -4 - (-4) + c
14 = c
So, the equation is y = -4/5x + 14
Answer:
15 inches
Step-by-step explanation:
Suppose length of original square is L inches.
Now, to form a new square the length increases by 2.5 inches
So, new length=L+2.5 inches
Given that, perimeter of new square =70 inches.
Formula:-
Perimeter=4*length of square
Therefore 70=4*(L+2.5)
70 =4 L+10
4 L=60
L=15 inches
