The answer is : A (-a,0)
It can't be 'b' as it is on y-axis.
So we are left with A.
On the x-axis, y=0. And x is -a as 'a' is a x-coordinate.
Hope it helped!!
Answer:
y=1, x=2
Step-by-step explanation:
x+y=3
x-y=1
Using elimination method
x-x+y--y=3-1
2y= 2
y=1
Substitute y=1 into equation 2
x-1=1
x=1+1
x=2
Answer:
1. T
2. T
3. T
4. F
Step-by-step explanation:
1. The tempature must be 0 degrees celcus or 32 degrees fahrenheit or below to snow.
2. An acute angle is less than 90 degrees
3. Supplementary angles are 2 angles that add up to 180.
4. Complementary angles are any 2 angles that add up to 90 degrees BUT they do not have to be only 45 degrees and can be any 2 degrees that add up to 90.
The answer is 150 grams i think
Answer:
Step-by-step explanation:
4*2=8, thats one rectangle (side)
8*2 is 16, thats TWO rectangles (sides)
7*4=28, thats one rectangle (front)
28*2=56, thats TWO rectangles (front and back)
7*2=14, thats one rectangle (top)
14*2=28, thats TWO rectangles (top and bottom)
add all of these surface areas together
TWO rectangles + TWO rectangles + TWO rectangles
28+56+16=100
As you can see, the 60cm2 is incorrect. 100cm2 is the real surface area of the shape
