How do I solve this?

Answer:

B. x + y = 14 and x - y = 2

Step-by-step explanation:

Sum means addition, so the sum of the tens digit (x) and the ones digit (y) is equal to 14 (x + y = 14).

Difference means subtraction, so the difference between the tens digit (x) and the ones digit (y) is 2 (x - y = 2).

I hope this helps =)

Answer:

Option B. will be the answer.

Step-by-step explanation:

If the tens digit is x and ones digit is y, then the number formed will be xy.

Now we fill form the equations as per statements given in the question.

"The difference between tens and unit digits is 2"

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

"Sum of the digits of two digit number is 14"

x + y = 14 -------(2)

Therefore, system of equations will be as the given equations 1 and 2.

Option B is the answer.

Answer:

-5 < x <=-2

Step-by-step explanation:

9<=1-4x<21

Subtract 1 from each side

9 -1<=1-1-4x<21-1

8 <= -4x < 20

Divide each side by -4.  That means to flip all inequalities

8/-4 >= -4x/-4 >20/-4

-2 >=x > -5

-5 < x <=-2

Answer:

its 18

Step-by-step explanation:

6+12=18

lol

Answer:

y = 18

Step-by-step explanation:

Just let x = 12

y = 6 + x

y = 6 + 12

y = 18

When x = 12, y = 18.

The graph is included to show you what y = 6 + x looks like and it also shows the point (12,18) = (x,y)

Final answer:

The number of eggs Ty has left after making 4 servings of scrambled eggs, using n eggs for each serving, is represented by the algebraic expression 10 - 4n.

Explanation:

To determine the number of eggs Ty has left after making scrambled eggs, we need to use a simple algebraic expression. If Ty started with 10 eggs and used n eggs for each of the 4 servings, we can represent the number of eggs used in total as 4n.

To find the number of eggs remaining, we subtract the total number of eggs used from the initial number of eggs:

Number of eggs remaining = Initial number of eggs - Number of eggs used

Number of eggs remaining = 10 - 4n

Answer:

[tex]\left(gof\right)\left(0\right)=16[/tex]

Step-by-step explanation:

Given functions are [tex]f\left(x\right)=-3x+4[/tex] and [tex]g\left(x\right)=x^2[/tex].

Using both functions we need to find about what is the value of [tex]\left(gof\right)\left(0\right)[/tex]. That can be done as shown below:

[tex]\left(gof\right)\left(0\right)[/tex]

[tex]=g\left(f\left(0\right)\right)[/tex]

[tex]=g\left(-3\left(0\right)+4\right)[/tex]

[tex]=g\left(0+4\right)[/tex]

[tex]=g\left(4\right)[/tex]

[tex]=4^2[/tex]

[tex]=16[/tex]

Hence final answer is [tex]\left(gof\right)\left(0\right)=16[/tex].

Step-by-step explanation:

Final answer:

Mary spends a total of 24 hours on math and art homework combined over a period of 4 weeks.

Explanation:

Mary spends 2 2/3 hours on math homework and 3 1/3 hours on art homework each week.

To find out how much time she spends on both subjects over 4 weeks, first, we add the weekly hours:

2 2/3 + 3 1/3 = 6 hours per week.

Next, we multiply this weekly total by 4 to determine the monthly total: 6 hours/week × 4 weeks = 24 hours.

Therefore, Mary spends a total of 24 hours on math and art homework over 4 weeks.

Answer:

The area of rhombus = 195 yd²

Step-by-step explanation:

Points to remember

Area of rhombus = d₁d₂/2

Where d₁ and d₂ are the diagonals of the rhombus

To find the area of given rhombus

Here diagonals of rhombus are given

From the figure we get,

d₁ = 13 + 13 = 26 yd and

d₂ = 7.5 + 7.5 = 15 yd

Area = d₁d₂/2 = (26 * 15 )/2 = 13 * 15 = 195 yd²

Therefore the area of rhombus = 195 yd²

The answer will be D

The equation of the line passing through points O(0,0) and P(8,-6) is y = -3/4x.

To find the equation of a line, we need to determine its slope and y-intercept. The slope can be found using the formula (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are coordinates of two points on the line. In this case, we have the coordinates of points O and P: O(0,0) and P(8,-6).

The slope of the line passing through O and P is (-6 - 0) / (8 - 0) = -6 / 8 = -3 / 4.

Since the line passes through the origin (0,0), its y-intercept is 0. Therefore, the equation of the line is y = -3/4x.

[tex]\left[\begin{array}{ccc}7\\4\\2\end{array}\right][/tex]

The answer is a single-column matrix (7,4,2)

Step-by-step explanation:

In such multiplication of matrices, you have to proceed by multiplying each ROW of the first matrix by the COLUMN of the second matrix.  So,

[tex]\left[\begin{array}{ccc}3&6&1\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (3 * 2) + (6 * 0) + (1 * 1) = 6 + 0 + 1 = 7[/tex]

then...

[tex]\left[\begin{array}{ccc}2&4&0\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (2 * 2) + (4 * 0) + (0 * 1) = 4 + 0 + 0 = 4[/tex]

and

[tex]\left[\begin{array}{ccc}0&6&2\end{array}\right] * \left[\begin{array}{ccc}2\\0\\1\end{array}\right] = (0 * 2) + (6 * 0) + (2 * 1) = 0 + 0 + 2= 2[/tex]

Answer:

1.68

Step-by-step explanation:

1. Move all of the terms to the left side and set the problem equal to zero.

2. Set each factor equal to zero.

For this case we have the following equation:

[tex]6 ^ {- x} + 4 = 3x-1[/tex]

We must clear the value of x, we follow the steps below:

We subtract 3x on both sides of the equation:[tex]6 ^ {- x} -3x + 4 = -1[/tex]

Add 1 to both sides of the equation:

[tex]6 ^ {- x} - 3x + 4 + 1 = -1 + 1\\6 ^ {- x} - 3x + 5 = 0[/tex]

Each side of the equation is drawn, then the solution is the x value of the intersection point.

where

B is the area of the base of the prism (triangular base in this problem)

L is the length of the prism (perpendicular distance between the top and the bottom)

we have

Answer: choice c

----------

This is a pretty poor question.  The questioner should clarify the exact dates of the given values of the CPI, and use the actual values.   44% is an alarming inflation rate, but fortunately a fictitious one here in the US.  US inflation in 2014 was around 0.7% so the number the student was asked to compute was off by more than a factor of sixty.

p = 1/6

Step-by-step explanation:

5/6 - 1/3 n = p(5-2n)

Multiply each side by 6 so we do not have any fractions

6(5/6 - 1/3 n) = 6*p(5-2n)

5 - 2n = 6p (5-2n)

Divide each side by (5-2n) to isolate 6p

(5-2n)/(5-2n) = 6p (5-2n)/ (5-2n)

1 = 6p

Now divide by 6 to get p alone

1/6 = 6p/6

1/6 = p

Answer: 6 meters per second

Step-by-step explanation:

Ben's average speed from Post A to Post C is 6 meters per second, calculated by dividing the total distance cycled (420 meters) by the total time taken (70 seconds).

The subject of the problem is calculating average speed. In this context, Ben's average speed can be calculated by dividing the total distance cycled by the total time taken.

Total distance is the sum of the distance from Post A to Post B and from Post B to Post C, which is 120 meters + 300 meters = 420 meters.

Total time is the sum of the time taken from Post A to Post B and from Post B to Post C, which is 15 seconds + 55 seconds = 70 seconds.

So, Ben's average speed=Total Distance/Total Time.
This equals 420 meters/70 seconds= 6 meters/second.

Therefore, Ben’s average speed for the entire distance from Post A to Post C is 6 meters per second.

ANSWER

[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]

EXPLANATION

The given ellipse has a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin.

The equation of an ellipse with vertex on the y-axis and center at the origin is given by

[tex]\frac{ {y}^{2} }{a ^{2} } + \frac{ {x}^{2} }{ {b}^{2} } = 1[/tex]

[tex]\frac{ {y}^{2} }{( - 7) ^{2} } + \frac{ {x}^{2} }{ {4}^{2} } = 1[/tex]

[tex]\frac{ {y}^{2} }{49} + \frac{ {x}^{2} }{ 16 } = 1[/tex]

The equation of the ellipse with a vertex at (0, -7), a co-vertex at (4,0), and a center at the origin is x^2/16 + y^2/49 = 1.

To find the equation of the ellipse in standard form, we need to identify the lengths of the major and minor axes. The given vertex at (0, -7) indicates that the semi-major axis length, a, is 7 because the distance from the center to a vertex measures the semi-major axis. Similarly, the co-vertex at (4, 0) represents the semi-minor axis length, b, which is 4.

Since the center is at the origin (0, 0), the standard form of the ellipse equation is given by x^2/b^2 + y^2/a^2 = 1. Plugging the values of a and b, we get x^2/4^2 + y^2/7^2 = 1. So, the equation of the ellipse is x^2/16 + y^2/49 = 1.
