the coordinates of endpoint B are (7,7)
Answer:
Solution given:
M(x,y)=(2,-1)
A
Let
B
now
by using mid point formula
x=
$ubstituting value
2*2=-3+a
a=4+3
a=7
again
y=
$ubstituting value
-1*2=5-b
b=5+2
b=7
the coordinates of endpoint B are (7,7)
Answer:
x=3, y=8; (3,8)
Step-by-step explanation:
To use the substitution method, first solve for a variable.
2x+y=14
2x+y(-2x)=14(-2x)
y=14-2x
Now substitute y in the other equation with 14-2x
5x-2(14-2x)= - 1
Simplify by multiplying inside the parenthesis.
5x-28+4x= - 1
Combine the x values
9x-28= - 1
9x=27
x=3
Now substitute the x value in to solve for y
2(3)+y=14
6+y=14
y=8
Answer:
0.4
Step-by-step explanation:
33+72+55+20=180
probability of choosing of choosing a maths teacher=72/180
=0.4
Answer:
the median is the middle number.
and the mode is the number that occurs most.
so if we put everything in order
53, 53.5, 54, 54.5, 54.5, 55, 57
so the mode would be 54.5 cause it occurs twice
and the median would be somewhere in between 54 and 54.5
Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x.
364 = 1.40x
Solving for x gives x = 260.
Thus, the autograph of the basketball player was worth only $260 last year.
