I need to explain how I calulated my answer but I don't understand this and I'm being timed ​

Answer:

3

Step-by-step explanation:

A term is any part of the equation that is separate from another part. In the equation, 2m - n + 3, 2m is a term because they are not separate, n is a term, and 3 is a term. I hope this helps and I hope it's not wrong but I don't think it is.

Answer:

use the slope intercept form of the equation

y = Mx +b

Step-by-step explanation:

6x+5y = -60

5y = -6x - 60

y = (-6/5)x -12

now just plug in zero for x in that above equation ... that will be the y intercept -12

and plug in zero for y and solve for x

0 = (-6/5)x -12

12= -6/5x

(-5/6)(12) = x

-10 = x  

Answer:

x = 2

Step-by-step explanation:

Given the expression 5x−4 = 3x +8, we are to solve for the value of x;

Step 1: Collect the like terms so that the variables are on one side and Constants on the other side

5x - 3x = 8-(-4)

5x - 3x = 8+4

Step 2: Evaluate the expression in both sides

5x-3x = 8+4

2x = 12

Step 3: Divide both sides by 2

2x = 12

2x/2 = 12/2

x = 6

Hence the value of x is 2

Answer:

  7n +5

Step-by-step explanation:

English tends to be ambiguous in statements like this. It is difficult to tell whether we want 5 more than the product, or 7 times the sum. Sometimes punctuation can help make the meaning clear. Assuming the former, a suitable expression is ...

  7n +5 . . . . the product of 7 and a number, increased by 5

Answer:

100 times

Step-by-step explanation:

Mathematically, the probability of getting a 3 or 4 is the probability of getting a 3 + probability of getting a 4

Probability of getting a 3 = number of 3/total number = 1/6

Probability of getting a 4 = number of 4/total number = 1/6

Thus, the probability of getting a 3 or 4 is 1/6 + 1/6 = 2/3

So the number of times will be probability multiply by number of rolls

= 2/3 * 150 = 100 times

Answer:

y + 17 = 7/3(x - 12)

General Formulas and Concepts:

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate

y₁ - y coordinate

m - slope

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Perpendicular lines have the negative reciprocal slope of the given line's slope.

Step-by-step explanation:

Step 1: Define

Line: y = -3/7x - 5

Slope m = -3/7

Point (12, -17)

Step 2: Find slope of perpendicular line

Take the negative reciprocal of the original slope.

Slope m = 7/3

Step 3: Write perpendicular line equation

x₁ = 12

y₁ = -17

m = 7/3

y + 17 = 7/3(x - 12)

________{$24.50 if x ≤ 1

r(x) - - - - - {24.50 + f(3 - 2) if x > 1

Flat rate paid for each additional 100 = $12

Step-by-step explanation:

Given that :

Cost of first 100 resume = $24.50

Flat rate for each additional 100 resumes

Total amount paid for 300 resumes = $48.50

Let x = number of sets of 100 resumes

Number of sets of 100 copies = {1, 2, 3}

Since first 100 copies = $24.50

r(x) = cost of printing resume

r(x) = 24.50 if x ≤ 1

Cost of additional 100 equals ;

Let flat rate paid for each additional 100 = f

r(x) = 24.50 + f(3 - 1) if x > 1

________{$24.50 if x ≤ 1

r(x) - - - - - {24.50 + f(3 - 2) if x > 1

The flat rate paid for additional 100 resume ;

(Total amount paid - cost of first 100) / 2

($48.50 - $24.50) / 2

$24 / 2

= $12

Answer:

Where is the problem??

Step-by-step explanation:

Given :-

AB = AC

Then :-

This triangle is an isosceles triangle .

Let x be the value of ∠CAB . Then, ∠ABC will also have the same value as ∠CAB , since∠CAB and∠ABC are both the opposite base angles of an isosceles triangle .

An equation to find ∠ABC and ∠CAB :-

[tex] = x + x + 60 = 180[/tex]

[tex] = 2x + 60 = 180[/tex]

[tex] = 2x = 180 - 60[/tex]

[tex] = 2x = 120[/tex]

[tex] = x = \frac{120}{2} [/tex]

[tex] = x = 60[/tex]

Which means that the measure of ∠ABC and ∠CAB both are equal to 60°, and this triangle is an equilateral triangle.

Therefore :-

[tex]\color{olive}\bold{m∠ABC\color{hotpink} = 60°}[/tex]

[tex]\large{\underline{\underline{\red{\tt{\purple{\leadsto } GiveN\:\: Figure:-}}}}}[/tex]

[tex]\setlength{\unitlength}{1 cm}\begin{picture}(12,8)\put(0,0){\line(1,0){4}}\put(4,0){\line(-1,2){2}}\put(2,4){\line( -1, - 2){2}}\put(2,4.2){$\bf B $}\put(0, - 0.3){$\bf A $}\put(4, - 0.3){$\bf C $}\put(2,0.2){\line(0,-1){0.4}}\put(0.8,2){\line(1,-2){0.2}}\put(3.3,0.1){$\sf 60^{\circ}$}\end{picture}[/tex]

[tex]\large{\underline{\underline{\red{\tt{\purple{\leadsto } AnsweR:-}}}}}[/tex]

It is given that AB = AC . Since two sides of the triangle are equal , hence it must be an isosceles triangle .

And we know that in an isosceles triangle two base angles are equal . So ∠ABC = ∠ ACB = 60° .

To calculate the y position given an x value, multiply the x value by -2 and subtract 3.

Answer:

switch the equation around so it looks like the slope intercept form

y= Mx + b

Step-by-step explanation:

y=3 - 1/2x

y= -1/2x +3

so when x = 0   you know this line is at 3 on the y axis

make a point on the graph at (0,3)

also you know that when x=6  they y is zero.. so

make a point on the graph at (6,0)

now draw a straight line between those two points on  your graph :)

Answer:

The range is all the y values.

Therefore, the range is : {-4,-2,2}.....I realize choice c has all the y values listed, however, if u have repeating y values, u only have to list it once.

Answer: After 8 months they will have equal number of DVD's.

Step-by-step explanation:

Given: Kaleb has 45 DVD's in his collection and Eileen has 61.

Let x= Number of months

If Kaleb buys 4 new DVD's each month and Eileen buys 2 new DVD's each month , then

Total DVD's Kaleb has = 45+4x

Total DVD's Eileen has = 61+2x

When they has equal DVD's , then

[tex]45+4x =61+2x\\\\\Rightarrow\ 4x-2x=61-45\\\\\Rightarrow\ 2x=16\\\\\Rightarrow\ x=\dfrac{16}{2}\\\\\Rightarrow\ x=8[/tex]

Hence, after 8 months they will have equal number of DVD's.

Answer:

16ft

Step-by-step explanation:

Please see attached diagram depicting the above scenario.

Since the ladder leans against a house, then it forms a right angled triangle while the hypothenus is 20 foot, the distance of the base of the ladder is 12 feet from the house, hence we are required to find the point at which the ladder touches the house I.e height, rep by h.

We will apply Pythagoras theorem to solve the problem.

h^2 = 20^2 - 12^2

h^2 = 400 - 144

h^ 2 = 256

h = √256

h = 16ft

Hence, the distance from the ground to the top of the ladder is 16ft.
