Express (x+7)^2 as a trinomial in standard form.

Answer:

(a,b) to (-a,-b)

Step-by-step explanation:

You can think of this as folding the paper horizontly and vertically, and see where the new point lies. You see that the x coordinate changes its sign  when the paper folds vertically, and the y coordinate changes its sign when folded horizontally.

But in general, if you have point (a,b) and if you rotate it 180 degrees, you just switch the signs, and you will get (-a,-b).

Ex. (-6,5) rotates 180 degrees and becomes (6,-5)

Answer:

(6,-5)

Step-by-step explanation:

Answer:

5y = 4x-25

Step-by-step explanation:

Let f(x) be regarded as y

So we have two points

(5,-1) and (0,-5)

We start by finding the slope of the line connecting the two points

m = y2-y1/x2-x1

m = -5+1/0-5 = -4/-5 = 4/5

The general equation of a straight line is;

y = mx + b

where m

is slope and b is the y-intercept

we already have the slope as 4/5

So;

y = 4x/5 + b

To get b, substitute one of the points

Let us use (0,-5)

-5 = 4(0)/5 + b

so b = -5

The equation is;

y = 4x/5 - 5

Multiply through by 5

5y = 4x - 25

The equation for total cost will be c = 60 + 29t and the total cost for 6 months will be $234.

It is given that charge of cellular connection for a phone is $60 and Economy plan is of $29 per month.

We have to find out the equation for total cost and the value of total cost for 6 months.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , multiplication , etc.

As per the question ;

Charge of cellular connection for a phone = $60

and

Economy plan of cellular connection = $29 per month

Let's assume c be total cost , t be no. of months.

So ;

The economy plan charges for t months will be ;

= 29 × t

and

The equation for total cost (c) will be ;

c = 60 + 29t

Also ;

The total cost for t = 6 months will be ;

c = 60 + 29 × 6

c = 60 + 174

c = $234

Thus , the equation for total cost will be c = 60 + 29t and the total cost for 6 months will be $234.

Answer: No.

Reason: (-1, -3) is (x, y) so, let's find -1 on the X scale first. Alright, -1 is in the blue, which is a great start. Now, it's -3 on the Y portion. And when you graph that, it's not in the blue shaded area, so no, it's not a solution. (TIP: Solution is the Shaded Area)

Answer:

6 miles

Step-by-step explanation:

because the common denominator is 12 so the man will walk 12 miles in 4 hours and the woman will walk 12 miles in 2 hours so they will meet in the middle

If point A and point B are 15 miles apart, they will meet H) 10 miles from point B.

The answer to the question is H: 10 miles.

To solve this problem, we can use the concept of relative velocity. Relative velocity is the velocity of one object as seen by another object. In this case, the man and the woman are moving towards each other, so their relative velocity is the sum of their individual velocities.

The man's velocity is 3 miles per hour and the woman's velocity is 6 miles per hour, so their relative velocity is 3 + 6 = 9 miles per hour.

We know that point A and point B are 15 miles apart, so they will meet when the distance between them is 0. The time it takes them to meet is 15 / 9 = 5/3 hours.

In 5/3 hours, the man will travel 3 * 5/3 = 5 miles and the woman will travel 6 * 5/3 = 10 miles. Therefore, they will meet 10 miles from point B.

Answer:

The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex] ⇒ c

Step-by-step explanation:

In the right angle triangle, we can use the trigonometry ratios to find the missing sides or angles

In the given right triangle

∵ There measure of an acute angle is 38°

∵ The adjacent side to this angle is a

∵ The opposite side to this angle is 6

→ We will use the tangent ratio because we have the opposite and

   adjacent sides of the given angle

∴ tan(38°) = [tex]\frac{6}{a}[/tex]

→ Multiply both sides by a to cancel the denominator in the right side

∴ a · tan(38°) = 6

→ Divide both sides by tan(38°) to find a

∴ a = [tex]\frac{6}{tan(38)}[/tex]

∴ The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex]

Answer:

A. Intercepted arc.

Step-by-step explanation:

From Geometry we know that arc ([tex]s[/tex]), dimensionless, is measured by the following equation:

[tex]s = \theta \cdot r[/tex] (1)

Where:

[tex]\theta[/tex] - Central angle, measured in radians.

[tex]r[/tex] - Radius, dimensionless.

If the circle has a radius of 1. Then, we notice that arc is directly proportional to the central angle. Hence, the right answer is A.
