Answer:
point (-2,11) does not lie on the given line
Step-by-step explanation:
To find : Which of the following points does not lie on the line ?
Solution :
To determine the point lie on line or not we have to put points in equation if it satisfy then it lie otherwise not.
a) Point (1,8)
Line y=3x+5
Substitute x=1 and y=8
8=3(1)+5
8=8
(1,8) point lie on the line.
b) Point (4,12)
Line y=3x+5
Substitute x=4 and y=17,
17=3(4)+5
17=12+5
17=17
(4,17) point does not lie on the line.
c) point (-2,11)
Line y=3x+5
substitute x=-2 and y=11
11=3(-2)+5
11=-6+5
11 is not equal to -1
d) Point(0.5)
Line y=3x+5
Substitute x=0 and y=5
5=3(0)+5
5=5
Answer:
y-intercept = -12
Step-by-step explanation:
The y-intercept is the "y" value when x = 0. You can find the y-intercept by plugging 0 into the equation and simplifying.
y = 4x - 12 <----- Original equation
y = 4(0) - 12 <----- Plug 0 in "x"
y = 0 - 12 <----- Multiply 4 and 0
y = -12 <----- Subtract 12 from 0
This is a simple math problem.
To find how many shirts Deena bought first, subtract
9x+25=88
-25 -25
Then
9x=63
Divide by 9
9/9=1
and
63/9=7
x=7
Thus, Deena bought 7 shirts.
Answer:
Step-by-step explanation:
2x+5y = 13
2(8-3y)+5y =13
16-6y+5y = 13
y=3
x =8-3y = -1
A semi-circle is equal to 1/2 of a full circle. To find the area, we can find the area of the whole circle, then divide it by 2.
radius = 10/2 = 5
A = pi x 5^2
A = 25pi
25pi/2 = 12.5pi
A = 12.5pi = 39.25 units^2
Hope this helps! :)
