How many solutions are there to this system of equations? On a coordinate plane, 2 lines have equations y = one-fourth (x minus 4) and y = one-fourth x minus 1.
a. one solution
b. no solution
c. infinitely many solutions
d. it cannot be determined without solving

Answers

Answer:

b. no solution

Step-by-step explanation:

y=1/4x-4

y=1/4x-1

This pair of equations has the same slope, meaning that they are parallel lines. Parallel lines never intersect so there is no result of solving this system of equations. Therefore, the correct answer would be b, that this system of equations has no solution.

NO solution

match each function with its rate of growth or decay

Answers

Answer:

y=5(1.05)^t=5% rate of growth

f(t)=50(0.95)^t=5% rate of decay

g(t)=50(1.5)^t=50% rate of growth

y=5(.5)^5=50% rate of decay

Step-by-step explanation:

y=5(1.05)^t= 1+x=1.05. x=0.05. 0.05= 5%, 5% rate of growth,

f(t)=50(0.95)^t=1-x=0.95, x=-0.05=-5%=5% rate of decay

g(t)=50(1.5)^t=1+x=1.5, x=0.5=50%, 50% rate of growth

y=5(.5)^5=1+x=0.5, x=-0.5=50%, 50% rate of decay

If this helps please mark as brainliest

The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.

What is an exponent?

Consider the function:

y = a (1 ± r)ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction or 100r %

If there is a minus sign, then there is exponential decay happening by r fraction or 100r %

The functions are given as,

y = 5 · (1.05)ⁿ

y = 5 · (1 + 0.05)ⁿ

The growth rate is 5%.

y = 50 · (0.95)ⁿ

y = 50 · (1 - 0.05)ⁿ

The decay rate is 5%.

y = 50 · (1.5)ⁿ

y = 50 · (1 + 0.5)ⁿ

The growth rate is 50%.

y = 5 · (0.05)ⁿ

y = 5 · (1 - 0.5)ⁿ

The decay rate is 50%.

The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.

Answers

Answer:

Use absolute difference

Step-by-step explanation:

Given

The given parameters can be represented as:

[tex]Expense > Income[/tex]

[tex]Income - Expense< 0[/tex]

Required

Eliminate negative difference

To eliminate negative difference, Sara has to  make use of absolute difference when calculating the difference between her income and expense.

Take for instance:

[tex]Income = 10[/tex]

[tex]Expense = 12[/tex]

The difference between both is:

[tex]Income - Expense = 10 - 12[/tex]

[tex]Income - Expense = -2[/tex]

But if she uses absolute difference, the result will be:

[tex]|Income - Expense| = |10 - 12|[/tex]

[tex]|Income - Expense| = |-2|[/tex]

[tex]|Income - Expense| = 2[/tex]

The formula for the volume of a rectangular prism is volume = length × width × height.


Which of the following is the BEST estimate of the volume of the rectangular prism below?

A. 16 cubic units

B. 54 cubic units

C.90 cubic units

D. 120 cubic units

Answers

Length x width x height would be 9.7 x 3.4 x 2.9 and that equals 95.642 so your closest answer would be C

Answer:

C

Step-by-step explanation:

The formula to work out the volume of a rectangular prism is:

V= w*h*l

Let's plug these nums. in:

V = (2.9)(9.7)(3.4) = 95.642

The closest answer is C ~ 90 cubic units
