Answer:
Given the equations:
.....[1]
....[2]
Substitute the value of x in [1] we get;'
Use identity: 
Combine like terms;
Subtract 36 from both sides we get;
By zero product property, we get;
y = 0 and 
Substitute these y values in [2] to get x values;
For y = 0 we have;
x = 2(0) +6 = 0+6 = 6
For x = -4.8
x = 2(-4.8)+6 = -9.6 + 6 = -3.6
Therefore, the solution for the given equations are; (6, 0) and (-3.6, -4.8)
Answer:
Step-by-step explanation:
We can solve the problem in this way:
- The 1st information that we have is that the four numbers are even and consecutive integer. Let's call these numbers A, B, C and D. This means that:
(since the distance between two even consecutive numbers is 2)
- The 2nd information that is given is that the sum of the first and third multiplied by 3 equals 28 less than 5 times the fourth, so:
(1)
Now we rewrite eq(1) by using:
and
(obtained by combining the 3 first equations)
So we get:
Solving this equation for C,
So the other numbers are:
The area of the park without fountain is about 819.76 square yards.
Human and non-human species possess a mental system of number representations that appear early in the lifespan and that supports approximate number skills, such as numerical estimation or number comparison. With the later acquisition of language and of symbolic numbers, human beings also develop exact number skills that allow using numbers precisely, such as in counting and arithmetic. The current review points out the behavioral data which either support or challenge these contrasting proposals. In an attempt to provide a comprehensive overview of these mixed data, we carefully took into account the heterogeneity of the available studies regarding the kind of tasks, stimuli or ages of assessment. Also, you can show how the numbers are related simply by identifying the tenth place value of each digit.
I think this is it not sure tho
