Answer:
y = - 
Step-by-step explanation:
Substitute x = - 3 into the expression
2x - 7y = 30
2(- 3) - 7y = 30
- 6 - 7y = 30 ( add 6 to both sides )
- 7y = 36 ( divide both sides by - 7 )
y = 
= - 
Answer:
C
Step-by-step explanation:
the negative sign in -0.3 implies that it is below and the only answer choice with the word below is
C: New orleans is 0.3m below sea level
Answer:
GHS 940,000 and GHS 1,410,000
Step-by-step explanation:
Total Ratio, thus 2+3 = 5 = 2,350,000
2/5 × 2,350,000 = 940,000
3/5 × 2,350,000 = 1,410,000
In conclusion, the money was shared at GHS 940,000 and GHS 1,410,000 among the two.
The piecewise function graphed on the axes is defined as follows:
<h3>What is a piecewise function?</h3>
A piecewise function is a function that has different definitions, depending on the input.
For x up to 1, we have that there is a <u>linear function with an intercept of 5 and a slope of -2</u>, hence the definition is:
f(x) = -2x + 5, x ≤ 1.
For x greater than 4, we have a <u>linear function with a slope of 2,</u> hence:
f(x) = 2x + b.
When x = 5, f(x) = 6, hence the value of b is found as follows:
6 = 2(5) + b
10 + b = 6.
b = -4.
Hence the second definition is:
f(x) = 2x - 4, x > 4.
