Answer:The diameter is 12cm
Step-by-step explanation:
Answer: $817.35
Step-by-step explanation:
150x4 = 600
600+217.35 = 817.35
8x²+3y²=24
8x²+3y²-24=0
Let x be 1 ,
Therefore
8+3y²-24=0
3y²-16=0
3y²=16
y²=16/3
y=4/1.7
y=40/17

Answer:
Step-by-step explanation:
As we move from the x-intercept (-2, 0) to the y-intercept (0, 4), x increases by 2 (this is the run) and y by 4 (this is the rise). Thus, the slope of this line is
m = rise/run = 4/2 = 2.
Given the y-intercept (0, 4) and the slope (2), the slope-intercept form of the equation of this line is y = 2x + 4.
From this we get the point-slope form:
y = 2x + 4 becomes y - 4 = 2(x - 0), or just y - 4 = 2x.
Answer:
The cost of 4 medium pizzas:
4 (x - 3)
Step-by-step explanation:
#3
x = the cost of a large pizza
medium pizza costs $3 less than a large pizza. So it's x - 3
If 4 medium pizzas then it will be: 4 (x - 3)
