Answer:
choice b because it is constantly going up the same amount.

6pink 7purple. total count 13.
without replacement draws 1 and then another. (odds of drawing purple)
first draw 7/13
second draw 6/12
7/13•6/12 = 42/156 or 21/78 or 7/26
with replacement.
first draw 7/13
second draw 7/13
7/13•7/13 = 49/169
-------------3.
total $8.40, p=n-60
60•5¢= $3.00
$8.40-$3.00=$5.40
1¢+5¢= 6¢
$5.40/6¢=90¢
1¢•90=90¢
5¢•90=$4.50
150•5¢=$7.50
90•1¢= $0.90
$7.50+$0.90=$8.40
Answer:
Missing value is -4/3 and whole solution can be written as ( 8,-4/3)
Step-by-step explanation:
Given equation 2x+3y=12
solution ( 8,)
solution is form (x,y) hence in (8,) x is given as 8 while y is missing to find y
we will plug 8 as value of x in equation 2x+3y=12. From this equation we will find the missing value.
2x+3y=12
=> 2*8+3y=12
=> 16 + 3y = 12
=> 3y = 12-16= -4
=> y = -4/3
Thus, missing value is -4/3 and whole solution can be written as ( 8,-4/3)
Answer:
y = 9
Step-by-step explanation:
To solve this question we will use the property of perpendicular lines,
Where and are the slopes of two lines perpendicular to each other.
Slope of a line passing through two points and is given by,
Slope of a line which passes through the points A(4, 2) and B(-1, y) will be
Slope of the line given in the graph [passing through (2, 4) and (-5, -1)]
From the property of perpendicular lines,
5y - 10 = 35
5y = 45
y = 9
Answer:
(1/3)/(1/3)=3/3=1
(1/3)/(1/3)=3/3=1ms-1
u get the speed or velocity by dividing the y axis(metres) over x axis(seconds)
which is metres (m)/seconds (s)= ms-1
so
take from the graph the differences of y axis divided by that of the x axis
1/1=1ms-1
