The solution to the inequality, 1/2x - 3 < -1 3/8, is x < 13/4. See the graph below.

Given the inequality, 1/2x - 3 < -1 3/8, solve to find the value of x, which is the solution to the inequality.

1/2x - 3 < -1 3/8 [given]

1/2x - 3 < -11/8

Add 3 to both sides of the equation:

1/2x - 3 + 3 < -11/8 + 3 [addition property of equality]

1/2x < 13/8

Multiply both sides by 2:

1/2x * 2 < 13/8 * 2 [multiplication property of equality]

x < 13/4

The solution to this inequality, x < 13/4 is given in the graph below.

Required equation of points plotted on graph relating range gain(k) and charging time(t) is k=4t.

A two-variable linear equation is one in which both variables have exponent 1.

An object in geometry known as a line is simply one that is described as being straight, thin, one-dimensional, zero width, and extending on both sides to infinity.

In essence, a straight line is just a line devoid of any bends.

Additionally, we can state that any line that crosses two certain points on the same plane will be singular.

Straight line form

m= y 2. – y 1/x 2-x 1

y-y 1=m (x-x 2)

A (0,0) and B (5,20)

([tex]x_{1}[/tex],[tex]y_{1}[/tex]  ) = (0,0) and ([tex]x_{2}[/tex],[tex]y_{2}[/tex]) = (5,20)

m = 20-0/5-0

   = 20/5

   = 4

([tex]x_{1}[/tex],[tex]y_{1}[/tex]  ) =(0,0)

y-0=4(x-0)

y=4x

Replace y with k and x with t

On solving the provided linear equation question - Jolly = $17.4, Jimmy =2x-30  =4.8 and Johnny = 2x=34.8

A linear equation has the algebraic form y=mx+b. where m is the slope and b is the y-intercept, consisting of a first-order (linear) term and a constant. If x and y are variables, the above is sometimes called a "two-variable linear equation".

Take Jolly's expenditure as x.

Jimmy would have spent twice as much as Jolly.

Johnny Equals 2x-30 if Johnny spent $30 less than Johnny.

Total amount spent: $57

Therefore,

[tex]x+ (2x-30) + 2x = 57\\ x+ 2x -30 +2x =57.\\ 5x = 57+ 30\\[/tex]

x = 87/5

x= 17.4

The interval where the cosine function is increasing is (π, 2π).

The cosine function for the interval (0, π/2) gives

cos(x) = cos(0) = 1

cos(x) = cos(π/2) = 0

So, the value of the function is decreasing in this interval.

Then, for the interval (0, π), it gives

cos(0) = 1; cos(π) = -1

So, the value of the cosine function is decreasing in this interval.

Then, for the interval (π/2, 3π/2), it gives

cos(π/2) = 0

cos(π) = -1

cos(3π/2) = 0

So, the value of the function decreases up to x = π and then increases up to the same value as before i.e., cos(π/2) = cos(3π/2).

Then, for the interval (π, 2π), the cosine function gives

cos(π) = -1

cos(2π) = 1

Thus, the cosine function in this interval increase from -1 to 1.

Therefore, in the interval (π, 2π), the cosine function is increasing.

a. The given sequence is not an arithmetic sequence.

b. The distance a falling body covered in t = n seconds of movement is 5n²meters.

What is the distance?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

Here, we have

a. A sequence can be said arithmetic sequence if the difference between any two consecutive terms remains the same.

In this case, the difference between 20 and 5 is 15, and the difference between 45 and 20 is 25, this shows that the difference between two consecutive terms is not the same.

Hence, it can be said that the given sequence is not an arithmetic sequence.

b. To evaluate the distance covered by the body in “n” seconds, Substitute t=n in d(t) then d(n) will represent the distance covered by the body in “n” seconds

d(n)=1/2 g(n)²

d(n) = 1/2(10)(n)²

d(n) = 5n²meters

Hence, the distance a falling body covered in t = n seconds of movement is 5n²meters.

Answer: f = p * (1 + r) ^ n

f is the future value.

p is the present value.

r is the interest rate per time period.

n is the number of time periods.

time periods are months.

rate is the percent divided by 100.

p = 100

r = 6% per year / 12 = .5% per month / 100 = .005 per month.

n = 2 years * 12 = 24 months.

formula becomes f = 100 * (1 + .005) ^ 24

solve for f to get:

f = 112.7159776 = 112.72

Step-by-step explanation:

Therefore the solution for this question is  the unit price of each pair of gloves is $7.99.

One of the four fundamental arithmetic operations, or the process by which two or more numbers are added together to create a new number, is division. Multiplication, addition, and subtraction round out the list of operations.

Here,

The cost of 6 pairs of gloves  = $47.94

Now, the unit price = Price per unit of the given item

Let x be the unit price of the glove

thus

x=47.94/6

x=7.99

or it can be written as price of glove=$7.99

b)   - 56.25% (or -56% with 2 sig figs

Step-by-step explanation:

Calculate the total distance Ahmad jogged on both days.  This will require a conversion unit to make the distances the same units.

Sat.:  3200 m

Sun:       1.8 km

(1,000m/km)

(1.8km)*(1,000 m/km) = 1,800 m jogged on Sunday

Total distance jogged = 3,200 m + 1,800 m = 4,000 meters total jogged

a)  Percentage jogged on Saturday:

 (3,200 m)/(4,000 m) = 0.80 or 80%

b)  Percentage Decrease (From Saturday to Sunday):

    Sat:  3200 m

    Sun: 1800 m

Difference = 1400 m (decrease)

Percentage Decrease = (1800/3200) = 56.25%

Ahmad's distance on Sunday was a 56.25% decrease from Saturday.
