Answer:
y = negative four-thirds x + StartFraction 31 Over 3 EndFraction
y = 2 x + 7
Step-by-step explanation:
Let x denote the smaller number and y denote the larger number.
Part 1
The equation presented indicates that four times some number added to three times a larger number equals 31.
This translates to:
From here, solving for y yields:
- 4x + 3y=31 ⇒ 3y= -4x+31 ⇒ y= (-4x+31)/3 = - 4/3x + 31/3
⇒ y= - 4/3x + 31/3
This indicates the correct response for this scenario:
y = negative four-thirds x + StartFraction 31 Over 3 EndFraction
Part 2
The statement that seven subtracted from the larger number equals twice the smaller number translates to:
y-7= 2x
Further, solving for y yields:y-7= 2x ⇒
y= 2x+ 7
The correct answer for this equation is:
y = 2 x + 7
It should be 94, I hope this provides assistance
The blue line depicted in the attached image illustrates the reflection of f(x) across the x-axis.
To elucidate, the function f(x) is an exponential function displaying the characteristics: the y-intercept calculates as f(0) = 6(0.5)⁰ = 6; the multiplicative rate of change is 0.5, signifying a decay function (decreasing); and the horizontal asymptote exists at y = 0, defining the limit of f(x) as x approaches positive infinity. The reflection across the x-axis for f(x) results in a function denoted as g(x) = -f(x), leading to g(x) reflecting the features discussed including growth into the third quadrant while never intersecting the x-axis. Therefore, using these insights, it is feasible to sketch the corresponding graph across the x-axis.
Answer:
The attached figure illustrates the graph.
Step-by-step explanation:
Let
x represents the count of open acres
y depicts the total developed acres
It is established that
corresponds to inequality A
corresponds to inequality B
Keep in mind that
if the open acres, x, is limited to a maximum of 1, then it follows that x must adhere to ≤ 1
The system of equations can be solved by graphing
The solution is found in the shaded area (Note Negative acreage counts are not permissible)
The attached figure serves as a visual representation.
I divided by 100 and shifted the decimal point two places left.
