Any value you choose for x will make the equation a TRUE statement. This type of equation is called an identity, and the solution set is all real numbers.
An identity is an equation that, regardless of the values used, is always true.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
An identity is an equation that, regardless of the values used, is always true.
For the linear equation y = mx + c, all the values of the variable x are real numbers because the quadratic function is defined.

What is the value of x
Answer:
x = 25
Step-by-step explanation:
The sum of the angles in a triangle are equal to 180 degrees. Since we know the value of one angle is 90 degrees, subtract 90 from 180 to get 90. Now we know the sum of the other two angles must equal 90 degrees. If we add the x and 2x + 15 together, we get 3x + 15 = 90. Subtract 15 from both sides to get 3x = 75. Divide both sides by 3 to get x = 25.
Consider the figure. Determine the value of x.
Answer:
x is 3.

On a 750 mile road trip Thelma drove 110 miles more than Louise. How far did each person drive?
Answer:
Thelma drove 430 miles, Louise drove 320 miles
Step-by-step explanation:
[tex]Distance = 750\\T + L = 750\\T = L + 110\\(L + 110) + L = 750\\2L + 110 = 750\\2L = 640\\L = 320\\T = 430[/tex]
8. An automobile traveled 320 miles in 6 hours. What is its average speed?
Answer:
The automobile's average speed is 53.33 mph.
Step-by-step explanation:
Since average speed equals total distance traveled divided by the time of the travel we have:
d = 320 mi the distance traveled
t = 6 hr the time of the travel
v = average speed
v = d/t
v = 320/6
v = 53.33 mph
Answer:
about 53 miles per hour
Step-by-step explanation:
320/6 is 53.33 repeated
you divide 320/6 because you need to know how many miles you going in an hour

Use technology to convert the polar coordinates (5, 6.1) to rectangular coordinates.
O (0.98, -0.18)
O (0.98, 0.18)
O (4.92, -0.91)
O (4.92, 0.91)
Answer:
(c) (4.92, -0.91)
Step-by-step explanation:
The conversion shown in the attached uses the complex number features of the calculator, so the y-coordinate is shown as an imaginary value. Rounded to 2 decimal places the conversion is ...
(r; θ) ⇔ (x, y)
(5; 6.1) ⇔ (4.92, -0.91)
__
The correct answer choice can be made without the use of technology. The sum of the magnitudes of the values of x and y must not be less than r, eliminating the first two choices. The angle 6.1 radians is near the angle 6.28 radians (2π), so is almost 360°. It will be a 4th-quadrant angle, so its y-component will be negative (eliminating the last choice).
The only viable choice for polar coordinates of radius 5 and angle 6.1 radians is the third choice: (4.92, -0.91).
__
Additional comment
The angle given has no units, so we assume it is given in radians. A calculator can only give a proper answer if it is set to radians mode for angles.

The circumference of the circle is 106.76 km.
What is Circumference of a Circle?Circumference of a circle is defined as the total length of the boundary of the circle.
The concept is same as the perimeter for straight sided figures.
Given that,
The diameter of a circle is 34 kilometers.
Diameter of the circle = 34 kilometers
Radius of the circle = Half of diameter = 34 / 2 = 17 km
Circumference of the circle = 2πr, where r is the radius of the circle.
Circumference = 2π × 17
= 34π
= 106.76 km
Hence the circumference of the circle is 106.76 km.

The equation y = 10x describes the amount of money Miranda earns, where x is the number of
hours she works and y is the amount of money she earns.
The table shows the amount of money Tommy earns for different numbers of hours worked.
(a) how much money does miranda earn per hour ? SHOW UR WORK.
(b) who earns more per hour? JUSTIFY YOUR ANSWER .
HELP !! ESPECIALLY IF UR IN k/12. THERES A PICTURE W/ MY QUESTION
Answer:
Miranda. Because she earns $10 per hour while Tommy earns $8 per hour.
Step-by-step explanation:
y = 10x <--- 10 is the amount she earns per every x, which is the number of hours she works.
Tommy's equation is y = 8x
Because if you plug in his values of time (x) and total cash earned (y) you get:
32=?4
Read the above ^ as " 32 = blank multiplied by four "
subtract both sides by four to find blank
Our blank equals 8, which is the amount Tommy makes per hour.
A circular mirror is surrounded by a square metal frame. The radius of the
mirror is 4x. The side length of the metal frame is 16x. What is the area of the
metal frame?
Answer: [tex]= 240x^2[/tex]
Step-by-step explanation:
Area of the entire frame = [tex](16x)^2 = 256x^2[/tex]
Area of the mirror = area of a circle = [tex]\pi r^2[/tex]
= [tex]\pi(4x)^2[/tex]
Area of the metal frame surrounding the mirror = square area - circle area
[tex]= (16x)^2-(4x)^2[/tex]
