algebra unit 8 lesson 1 assessment question 4
2y – 3x = 9
4y + 3x = 12
A.
coincident
B.
not enough information
C.
inconsistent
D.
consistent and independent
Answer: D. consistent and independent
Step-by-step explanation:
The given system is
When we compare the coefficients of the corresponding variables of both the equations we get,
For y,
For x,
And ,
⇒ The system in independent.
Therefore the system has one unique solution.
Since, if a system has a unique solution then the system is consistent .
Therefore, the system is consistent and independent.
Answer:
πr²
Step-by-step explanation:
The surface area of a circle is πr²
Pie is 22/7 or 3.14
While the radius of a circle is any line from the centre of a circle to any part of the circumference of the circle. A diameter is any line that cuts the circle into two equal halves, cutting the circle from the centre.
To get the surface area of a circle, you draw a line from the centre of the circle, and then touch any part of the circumference of the circle. Then you measure the line, that's the radius.
If for instance, the radius gives 7cm, you find the Square, And then multiply it with pie.
22/7 X 7 ²
22/7 X 7 X 7
22 X 7
154cm²
