When Billy's asked how old he is, he replies, "In two years I will be twice as old as I was five years ago." How old is he?
brainliest to whoever answers
Answer:
12 years old
Step-by-step explanation:
Set up the following equation:
x + 2 = 2(x - 5) (distribute the 2)
x + 2 = 2x - 10 (subtract 2 from both sides)
x = 2x - 12 (subtract 2x from both sides)
-x = -12 (multiply both sides by negative 1)
x = 12
Brainliest, please :)
Answer: 12
Step-by-step explanation:
Let's algebraically represent this situation. Say his current age is x. We can rephrase the sentence to say that in two years, his age is the same as twice his age 5 years ago.
The phrase "in two years" means when his age is 2 more than his current age, or x + 2.
The phrase "same as" represents equality. The expressions on both sides have the same value.
The phrase "twice his age 5 years ago" is his age minus 5, multiplied by 2. We can write this as 2*(x-5).
Now that we have "translated" the equation from words to numbers, let's put it all in one equation and solve:
[tex]x+2=2(x-5)[/tex]
[tex]x+2=2x-10[/tex] [Distributive Property]
[tex]x+2-2x-2=2x-10-2x-2[/tex] [Adding -2x-2 to both sides]
[tex]-x=-12[/tex] [Combining like terms and simplifying]
[tex]x=12[/tex] [Multiplying both sides by -1 to remove the negative]
Hence, Billy's age is 12.

Ray and Kelsey have summer internships at an engineering firm. As part of their internship, they get to assist in the planning of a brand new roller coaster. For this assignment, you help Ray and Kelsey as they tackle the math behind some simple curves in the coaster's track.
Part A
The first part of Ray and Kelsey's roller coaster is a curved pattern that can be represented by a polynomial function.
Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only. Is there a way for the both of them to be correct? Explain your answer.
Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = (x + 2)(x − 1)(x − 2)
g(x) = (x + 3)(x + 2)(x − 3)
g(x) = (x + 2)(x − 2)(x − 3)
g(x) = (x + 5)(x + 2)(x − 5)
g(x) = (x + 7)(x + 1)(x − 1)
Create a graph of the polynomial function you selected from Question 2.
From the information given about the polynomial function, It is correct to state that there is a way for both of them to be correct. See the explanation below and the attached for the graph related to the second question.
What is the explanation for the above?A polynomial could only have a number of zeros equal to its degree. A third degree polynomial can thus have three zeroes, but Ray claims the polynomial has four Intercepts.
While the words "zeroes" and "intercepts" are sometimes used interchangeably, a zero is officially an x-intercept. A function can also have a y-intercept, therefore a cubic can have four intercepts in total, albeit only three will be zeroes.
The zeros of g(x)= x3-x2-4x+4 are -2,2, and 1. End behavior, the Y- intercept, the axis of symmetry, and the vertex are other important characteristics of polynomial functions.

Option A is correct.
When we divide one number by another, the result is a quotient. Although a quotient can be greater than the divisor, it will never be greater than the dividend.
In mathematics, the outcome of dividing a number by any divisor is known as the quotient. It refers to how many times the dividend contains the divisor.
After the division has been done, the quotient is obtained. This signifies that the quotient is the result of dividing a dividend by a divisor.

Meters
W
Answer:
15m
Step-by-step explanation:
Let w be the width, l the length and p the perimeter.
We know, by definition, that p = 2w + 2l. We also know that p = 80m and l = 25m.
So we can re-write the perimeter formula as:
80 = 2w + 50
2w = 30
w = 15m
So we now know that the width is 15m.
use the sum to product formula to find exact values: if cos255 - cos195 = squrtroot a/ 2 then a=
By applying trigonometric expression and direct comparison, we conclude that a = 2 such cos 255° - cos 195° = √a / 2
How to analyze a trigonometric expression
In this question we need to simplify a trigonometric expression in order to find the value of a. In this case, we need to use the following formula:
[tex]\cos \theta - \cos \xi = - 2\cdot \sin \left(\frac{\theta + \xi}{2} \right)\cdot \sin \left(\frac{\theta - \xi}{2} \right)[/tex]
Then,
cos 255° - cos 195° = - 2 · sin 225° · sin 30°
cos 255° - cos 195° = - 2 · sin (- 135°) · sin 30°
cos 255° - cos 195° = 2 · sin 135° · sin 30°
cos 255° - cos 195° = 2 · (√2 / 2) · (1/2)
cos 255° - cos 195° = √2 / 2
Then, by direct comparison we find that a = 2.

The measure of angle C (m ∠C) is 40°
Calculating angles in a triangleFrom the question, we are to determine the measure of angle C (m ∠C)
In any given triangle, the sum of all the angles is 180°
Thus,
In ΔABC, the angles sum up to 180°
That is,
∠A + ∠B + ∠C = 180°
From the given information,
m ∠A = 80°, m ∠B = 60°
Thus,
80° + 60° + m ∠C = 180°
140° + m ∠C = 180°
m ∠C = 180° - 140°
m ∠C = 40°

Rafael earns $35 more per week than Andrew. If their weekly salaries total $715, what amount does each earn?
Answer:
Rafael earns $375
Andrew earns $340
Step-by-step explanation:
Here, we will set up a system of equations where r represents Rafael and a represents andrew.
r = a + 35
r + a = 715
Next, we substitute a + 35 for r in the second equation.
(a + 35) + a = 715 (combine like terms)
2a + 35 = 715 (subtract 35 from both sides)
2a = 680 (divide both sides by 2)
a = 340
To solve for r, we can plug 340 for a into either equation.
r = (340) + 35
r = 375
We can double check by plugging both values into the other equation.
375 + 340 = 715 (yes, it works!)

Find the point on the line y = 5x + 2 that is closest to the origin.
Answer: [tex]\left(-\frac{5}{13}, \frac{1}{13}\right)[/tex]
Step-by-step explanation:
The shortest distance from a point to a line is the perpendicular distance. The origin is essentially a point with coordinates (0,0); hence, we have to find the equation of the line that's both perpendicular to [tex]y=5x+2[/tex] and crosses the origin.
We can do this by recognizing that slope of a perpendicular line is the opposite reciprocal of the slope of the original line.
Opposite Reciprocal of 5: [tex]-\frac{1}{5}[/tex]
Now that we have the slope and the point, we can use the point-slope form to get the equation of the perpendicular.
Point-Slope Form: [tex]y-y_1=m(x-x_1)[/tex] (m is slope, [tex]x_1[/tex] and [tex]y_1[/tex] are the point's coordinates)
[tex]y-0=-\frac{1}{5}(x-0)\\y=-\frac{1}{5}x[/tex]
Since we need to find a point on the original line that's closest to the origin, we need to find the intersection of the line and its perpendicular. We can do this by setting both lines equal to each other and solving for x and y.
[tex]5x+2=-\frac{1}{5}x\\25x+10=-x\\26x=-10\\x=-\frac{10}{26}\\x=-\frac{5}{13}[/tex]
Substituting x in any of the equations will give us y. Here, I will put it in the equation [tex]y=-\frac{1}{5}x[/tex]
[tex]y=-\frac{1}{5}*-\frac{5}{13}\\y=\frac{5}{65}\\y=\frac{1}{13}[/tex]
The closest point to the origin on the line [tex]y=5x+2[/tex] is [tex]\left(-\frac{5}{13}, \frac{1}{13}\right)[/tex]
The point on the line y = 5x + 2 that is closest to the origin is (-5/13, 1/13).
What is the point slope form?The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.
The given equation of a line is y=5x+2 ------(I)
The shortest distance from a point to a line is the perpendicular distance. The origin is essentially a point with coordinates (0,0); hence, we have to find the equation of the line that's both perpendicular to y=5x+2 and crosses the origin.
We can do this by recognizing that slope of a perpendicular line is the opposite reciprocal of the slope of the original line.
So, slope of perpendicular line is -1/5
The equation of the point slope form is: (y - y1) = m(x - x1)
Now, substitute m=-1/5 and (x, y)=(0, 0), we get
y-0=-1/5 (x-0)
y=-1/5 x -----(II)
Equate equation (I) and (II), we get
5x+2=-1/5 x
⇒ -x=25x+10
⇒ -26x=10
⇒ x= -5/13
So, y=-1/5 x =1/13
Therefore, the point on the line y = 5x + 2 that is closest to the origin is (-5/13, 1/13).
