Answers

Answer:

m + (m + 15) + (m + 2)

Step-by-step explanation:

Even thought we don't know the value of m, we can use expressions to represent it.

Hope this helps.

The required expression is m + (m + 15) + (m + 2) which represents the total number of miles Marla, Lawrence, and Jerry drove in all.

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.

Let's represent Marla drove "m" miles.

Since Lawrence drove 15 more miles than Marla.

So, this means the expression m + 15

Then Jerry drove 2 more miles than Marla.

So, this means the expression m + 2

Now, the total number of miles = m + (m + 15) + (m + 2)

This expression represents the total number of miles Marla, Lawrence, and Jerry drove in all.

What is the initial value of the equation shown?

y = −7x − 6

Answers

Answer:

[tex]y = -6[/tex]

Step-by-step explanation:

Given

[tex]y = -7x-6[/tex]

Required

Determine the initial value

The initial value of any equation is the point where

[tex]x = 0[/tex]

Substitute 0 for x in [tex]y = -7x-6[/tex]

[tex]y = -7 * 0 - 6[/tex]

[tex]y=0-6[/tex]

[tex]y = -6[/tex]

Hence, the initia; value is -6

The polynomial below is a perfect square trinomial of the form A2 - 2AB + B2.

9x^2-36x+16

A.True
B.False​

Answers

Step-by-step explanation:

9x² - 36x + 16

= (Ax - B)² = A²x² - 2ABx + B².

By Comparing Coefficients, we have:

A² = 9,

2AB = 36,

B² = 16.

It is obvious that A = 3 and B = 4.

However 2AB = 2(3)(4) = 24 which is not equal to 36.

Hence 9x² - 36x + 16 is not a perfect square trinomial.

Answer:

False

A. the equation has two true solutions
B. the equation had one true solution
C. the equation has one extraneous solution
D. the equation has one true solution and one extraneous solution ​

Answers

Answer:

C. the equation has one extraneous solution

Step-by-step explanation:

Given equation:

x/(x - 1) + 2/(x + 2) = -6/(x² + x - 2)

Common denominator is x² + x - 2, consider x ≠ 1 and x≠ -2

Multiply both sides by x² + x - 2:

x(x + 2) + 2(x - 1) = -6x² + 2x + 2x - 2 + 6 = 0x² + 4x + 4 = 0(x + 2)² = 0x + 2 = 0x = -2

There is one solution but it is not true one.

Option C is correct

Answer:

[tex] \frac{x}{x - 1} + \frac{2}{x + 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ \frac{x(x + 2) + 2(x - 1)}{(x - 1)(x + 2)} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 2x + 2x - 2 }{ {x}^{2} + 2x - x - 2} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 4x - 2 }{ {x}^{2} + x - 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ {x}^{2} + 4x - 2 = - 6 \\ {x}^{2} + 4x + 4 = 0 \\ {x}^{2} + 2 \times 2 \times x + {2}^{2} = 0 \\ {(x + 2)}^{2} = 0 \\ x + 2 = 0 \\ \boxed{x = - 2 }[/tex]

x =-2 is the right answer.

C. the equation has one extraneous solution.

Answers

Answer: y=-1/3x+5

Step-by-step explanation: I presume they want this in the y=mx+b format where m is the slope (change in y/change in x) of the line and b is the y-intercept (what y is when x is equal to 0). To answer this you need to choose any 2 points on this graph. For simplicity's sake, I'm going to choose (0,5) and (9,2). What's good about choosing (0,5) is that we now know the y-intercept is 5. Now, to find slope, subtract the y coordinate 2 from the y coordinate 5. You now know that the change in y is 3. Then, subtract the x coordinate 9 from the x coordinate 0. You now know that the change in y is -9. Finally, divide 3 (change in y) by -9 (change in x) and you should get  -3/9 which can be simplified into -1/3. So now that you have your y-intercept and your slope, all that's left to do in plug it into the format. So your answer should be y=-1/3x+5. Hope this helps you!

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?

Answers

Answer:

Mei descends faster

Mei's height decreases 5ft every second

Victor's height decreases 3.33 ft every second

Step-by-step explanation:

Given

Mel

[tex](x_1,y_1) = (2,50)[/tex]

[tex](x_2,y_2) = (5,35)[/tex]

Victor

[tex](x_1,y_1) = (1,60)[/tex]

[tex](x_2,y_2) = (4,50)[/tex]

Required

Who descend faster?

To do this, we simply calculate the slope/rate of both individuals

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For Mei:

[tex]m_1 = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex](x_1,y_1) = (2,50)[/tex]

[tex](x_2,y_2) = (5,35)[/tex]

[tex]m_1 = \frac{35 -50}{5 - 2}[/tex]

[tex]m_1 = \frac{-15}{3}[/tex]

[tex]m_1 = -5[/tex]

Mei descends at 5ft per second

For Victor:

[tex]m_2 = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex](x_1,y_1) = (1,60)[/tex]

[tex](x_2,y_2) = (4,50)[/tex]

[tex]m_2 = \frac{50-60}{4 - 1}[/tex]

[tex]m_2 = \frac{-10}{3}[/tex]

[tex]m_2 = -3.33[/tex]

Victor descends at 3.33ft per second

By comparison:

Mei descends faster

m is proportional to the cube of r. when r=3m,m=216.when r=5 find the value of m

Answers

Answer:

The value of m is 1000 for r=5

Step-by-step explanation:

Given that m is proportional to the cube of r

It can be written as:

[tex]m \propto\ r^3[/tex]

When the proportionality symbol is removed a proportionality constant is introduced in the equation.

Let k be the proportionality constant

[tex]m = kr^3[/tex]

Given

r=3,m=216

Putting the values

[tex]216 = k(3)^3\\216 = k * 27\\k = \frac{216}{27}\\k = 8[/tex]

The equation will now become

[tex]m = 8r^3[/tex]

Putting r = 5

[tex]m = 8(5)^3\\m = 8 * 125\\m = 1000[/tex]

Hence,

The value of m is 1000 for r=5

Which of the following statements best describes the relationship between the point (5,-20) and the system of
inequalities below?

Answers

Answer: The point (5,-20) only satisfies the second inequality statement in the system of inequalities shown.

Step-by-step explanation:

It isn't super clear exactly what you're asking, but the first thing we can do is see if the point (5, -20) satisfies the system of equations.

So, we start by plugging in -20 for y and 5 for x.

y > -2x-3

-20 > (-2)(5) - 3

-20 > -10-3

-20 > -13. - we can see that the coordinates DO NOT satisfy the first inequality, now we can try the second equation.

y ≤ 3x + 2

-20 ≤ 3(5) + 2

-20 ≤ 15 +2

-20 ≤ 17 - this inequality is true because -20 is indeed less than 17.

What equation is the rule for the function illustrated by the table of values?

Answers

Answer:

The equation which determined the rule for the function is:

y = 3x+2

Thus, option B is true.

Step-by-step explanation:

We know the slope-intercept form of line function is

y = mx+b

where m is the slope and b is the y-intercept

Given the table

x     -2       -1        0       1       2

y      -4       -1        2      5       8

Finding the slope between the points (-2, -4) and (-1, -1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-1\right)[/tex]

[tex]m=\frac{-1-\left(-4\right)}{-1-\left(-2\right)}[/tex]

[tex]m=3[/tex]

Thus, the slope of the function = m = 3

We know that the y-intercept can be determined by setting x = 0 and determining the corresponding y-value.

It is clear,

at x=0, y = 2

Thus, the y-intercept 'b' = 2

now substituting m = 3 and b =2 in the slope-intercept form

y = mx+b

y = 3x + 2

Therefore, the equation which determined the rule for the function is:

y = 3x+2

Thus, option B is true.

Given the 5 number summary information :

The Outlier :

Lower bound : Q1 - (1.5 * IQR)

Upper bound : Q3 + (1.5 * IQR

IQR = Q3 - Q1 = (86 - 72) = 14

Lower = 72 - (1.5 * 14)

Lower boundary = 51

Upper boundary = 86 + (1.5 * 14)

Upper boundary = 86 + 21 = 107

Values below 51 and values greater Than 107 are outliers.

Hence, 7, 36 and 123 are outliers
