Answer:
6.7 in bcoz 4-3.2=0.8 and 7.5-0.8=6.7
Answer:
56=29+a
Step-by-step explanation:
So 2 people gathered apples. That means there will be 3 numbers in the equation you are trying to make.
One number will be the amount of apples you gathered.
(as said, 29)
One number will be the amount of apples your friend gathered.
(you do not know this, so it will be a variable)
The last number will be the amount of apples you AND your friend gathered.
(as said, 56)
Since 56 is the amount of apples you and your friend gathered, its is equal to both other numbers combined.
to say that 56 is equal to both your apples and your friend's apples, you would say:
56 = 29 + a
(a is the variable)
To use this equation to find a, you would subtract 29 from both sides. It should look like:
27 = a
The slope of this line is -3/4
In order to find this, we look for two points on the line and then use the slope formula. Two points that are on the line are (0, 2) and (4, -1). Plug these into the following formula.
m (slope) = (y2 - y1)/(x2 - x1)
m = (-1 - 2)/(4 - 0)
m = -3/4
To find the volume you can use the subtraction technique. Volume is length x width x height. So find the volume of the whole shape, 8x10x6 = 480. Then you subtract the missing piece 6x5x6= 180. So the volume is 480-180=300m^3 If you don't understand this technique I can explain the dissection technique
Answer:
(- 3, 0 ) and (1, 0 )
Step-by-step explanation:
Given
y =2x² + 4x - 6
To find the x- intercepts let y = 0, that is
2x² + 4x - 6 = 0 ← divide all terms by 2
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
The x- intercepts are (- 3, 0 ) and (1, 0 )
