Step-by-step explanation:

The y -intercept in this situation mean that Jerry was given $75 for his birthday

The equation below is a linear equation.

y = 50x + 75

A linear equation is an equation that has a single variable raised to the power of 1. 50x is raised to the power of 1

75 represents the constant. This is the money he deposited in the account. 75 is the y-intercept. The y-intercept is the value of the line y when it crosses the y-axis

50x is the slope of the line. - 50 is the amount he puts in every month and x represents month.

The slope of a line also known as the gradient of the line determines the steepness and direction of a line. If the slope coefficient is less than zero, the slope is negative and it would decline from left to right

y is the dependent variable. It is the total amount he would have at the end of each month.  y depends on the constant term (75), the number of months(x) and the amount he deposits every month (50)

at the end of :

one month, he would have : 50(1) + 75 = 125

two months, he would have : 50(2) + 75 = 175

Step-by-step explanation:

Answer:

y = 4x - 4

Step-by-step explanation:

to write a linear equation you need to know 2 components:  slope and y-intercept

find slope by selecting 2 points, for example, (1,0) and (2,4)

slope ('m') = difference of y-values              4 - 0  =  4

                    difference of x-values             2 - 1        1

to find y-intercept ('b'), plug values into the slope-intercept form of a line, which is:

y = mx + b

you need a point and the slope of 4/1; can use any point

we'll use (2,4) where x =2 and y=4  and, again, m = 4

4 = 2(4) + b

4 = 8 + b

-4 = b

i dont get that either lol pain. why does school have to be so hard

Answer:  Choice A.  y + 5 = -2(x + 2)

================================================

Explanation:

Let's solve the given equation for y so we can find the slope.

3x - 6y = 2

3x = 2+6y

3x-2 = 6y

6y = 3x-2

y = (3x-2)/6

y = (3x/6) - (2/6)

y = (1/2)x - 1/3

The last equation is in y = mx+b form. We see that m = 1/2 is the slope.

Apply the negative reciprocal to go from 1/2 to -2/1 or just -2.

The original slope is 1/2, and the perpendicular slope is -2.

Rule: multiplying any two perpendicular slopes leads to -1 where neither line can be vertical.

Let's plug in m = -2, x1 = -2 and y1 = -5 into point slope form

y - y1 = m(x - x1)

y - (-5) = -2(x - (-2))

y + 5 = -2(x + 2)

Similar to motion sickness, cybersickness is a mix of sensations that develops when there is no actual physical movement. The three types of symptoms are nausea, oculomotor problems, and general disorientation.

Eye strain, weariness, and headaches are examples of oculomotor symptoms that result from overworking the nerve that regulates eye movement.

The symptoms of disorientation can include vertigo and dizziness. Additionally, numerous cybersickness symptoms, including trouble focusing and fuzzy vision, cross over into different categories.

As per the given results, there are two 1s and two 0s in the number lines of the trial. Hence, total response of "yes" is 4.

Answer:

24/2 slices

= 12/1

Step-by-step explanation:

Total slices of pizza = 8

Anna and Jose ate = 5

Slices of pizza remaining = 3

Zach and Sarah came over and Anna split the remaining slices evenly between them

That's is, 3 slices of pizza divided by 2 people

= 3/2

= 1 1/2 slices each

Each of Zach and Sarah ate 3/2 slices of pizza

fraction of the original pizza that Zach and Sarah each ate

= 3/2 of 8

a₃₀ = - 18

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = a₂ - a₁ = 10 - 11 = - 1, then

[tex]a_{n}[/tex] = 11 - (n - 1) = 11 - n + 1 = 12 - n , thus

a₃₀ = 12 - 30 = - 18

Answer:

The length of side along the river is 68 m

Step-by-step explanation:

Area of trapezium = 10200 m²

Length of side along the road (a) = x

Length of side along the river (b) = 2x

Height = 200 m

We need to find Length of side along the river.

The formula used is: [tex]Area\: of\: trapezium=\frac{a+b}{2}\times h[/tex]

Putting values and finding length:

[tex]Area\: of\: trapezium=\frac{a+b}{2}\times h\\10200=\frac{2x+x}{2}\times 200\\10200=2x+2\times 100\\\frac{10200}{100} =2x+2\\102=3x\\x=\frac{102}{3}\\x=34[/tex]

So, Value of x = 34

Length of side along the road (a) = x = 34

Length of side along the river (b) = 2x = 2(34) = 68

So, the length of side along the river is 68 m

Answer: A. The modes differ by 40 and the ranges differ by 40.

Step-by-step explanation:

The required, modes differ by 40 and the ranges differ by 40. Option A is correct.

To compare the modes and ranges of the given data, let's first find the modes and ranges.

Last Summer:

140, 220, 190, 180, 190

This Summer:

150, 170, 150, 190, 180

The mode is the value that appears most frequently in a dataset, while the range is the difference between the maximum and minimum values in a dataset.

The modes are as follows:
Last summer: The mode is 190 since it appears twice, more frequently than any other value.
This summer: The mode is 150 since it appears twice, more frequently than any other value.

The ranges are as follows:
Last summer: The range is 220 - 140 = 80.
This summer: The range is 190 - 150 = 40.

Now, let's compare the modes to the ranges:

Statement: The modes differ by 40 and the ranges differ by 40. Since the modes differ by 40 and the ranges differ by 40, the statement is true.

Therefore, the correct statement is:

A. The modes differ by 40 and the ranges differ by 40.

Answer:

10 inches.

Step-by-step explanation:

One stack has boxes that are 2 inches high, then the height of this stack can be only multiples of 2 inches.

The other stack has boxes that are 5 inches high, then the height of this stack can be only multiples of 5 inches.

The height of both stacks will be the same for all the common multiples of 2 and 5.

Because 2 and 5 are prime numbers, all the common multiples between 2 and 5 will be direct products of these two numbers.

Like 2*5 = 10

is both a multiple of 2 and 5 (is the first common multiple)

Then we can use stacks of 10 inches.

Such that, for the stack where each box is 2 inches high, we need:

10in/2in = 5

5 boxes.

And for the stack where each box is 5 inches high, we will need:

10in/5in = 2

2 boxes.

Alexander's new glasses cost would be the amount of $108.55 which is the correct answer would be an option (B).

The percentage is defined as a ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

We have been given that Alexander's new glasses normally cost $167 at a retailer, but he only paid 65% of the retail cost.

To determine the amount his new glasses cost

We have to calculate 65% of $167 which is the retail cost.

As per the given information, the solution would be:

⇒ 65% of $167

⇒ (65/100)(167)

⇒ (0.65)(167)

⇒ 108.55

Therefore, his new glasses cost would be the amount of $108.55.

Hence, option A is correct.          

Step-by-step explanation:

From the given right-angled triangle,

Using the formula to determine the area of the right-angled triangle

Area of the right triangle A = 1/2 × Base × Perpendicular
