In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25
in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1
in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.
5+ (-5) = 0
5- (-5) = 10

in two turns points=3-4=-1
in 6 turns=-1/2×6=-3 points

-23+40=17
she had 17 dollars balance.
Step-by-step explanation:
Given x intercept is 1, So (x,y) is (1,0)
When x intercept is 1 then y value is 0
Another point on the line is (-2,3)
Two points are (1,0) and (-2,3)
Find out slope using the two given points
Use point slope formula
m=-1 and point(1,0)
Point slope equation is
Equation of the line in slope intercept form is
Amount of money collected in the 2-day fundraiser is represented by the following equations:
- 12x + 4y = 152 .................. (i)
- 32x + 12y = 420 .................. (ii)
where x is the cost of a chicken lunch and y is the cost of a vegetarian lunch
Multiplying (i) with 3 and subtracting it from (ii)
36x + 12y - (32x + 12y) = 456 - 420
⇒ 4x = 36
⇒ x = 9
Put value of x in (i)
⇒ 12 × 9 + 4y = 152
⇒ 108 + 4y = 152
⇒ 4y = 44
⇒ y = 11
Hence, cost of the vegetarian meal is 11.
