Answer:

The second one is the correct answer g(x)=-1/4x-1/4

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° .

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:

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

Hi! Can I ask you a question?

Answer:

10.67 km/hr

Step-by-step explanation:

A crosstown bus travels 8 kilometers in 45 minutes, its average rate of speed is,  10.67 km/hr

In mathematics, Average is a values which we calculate by dividing sum of values of all the data-set by number of data-sets.

Average =  sum of values of all the data-set/number of data-sets

Given that,

A crosstown bus travels 8 kilometers

Time = 45 minutes =45/60 hr = 3/4 hr

Average speed = ?

Average speed = Total distance covered /Total time taken

Average speed = 8 km/(3/4)hr

                          = 10.6666 km/hr

Hence, The average speed is 10.67 km/hr

Answer:

Where is the problem??

Step-by-step explanation:

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)

Answer:

1. Anjali answered 10 questions incorrectly

2. Rohan answered 16 questions incorrectly

Step-by-step explanation:

1 .The mark given for one correct answer = 5

That means that the mark given for 10 correct answers = 5 × 10 = 50

But Anjali's score = 30

Also, the marks gotten for incorrect answers = 30 - 50 = -20

Mark given for one incorrect answer = -2.

Therefore, number of incorrect answers would be;

= (-20) ÷ (-2)

= 10

•Anjali answered 10 questions incorrectly.

2. Total marks = -12

Number of correct answers = 4

Total marks for correct answers = 4 × 5 = 20

Also, marks for incorrect answers = -2 × Number of incorrect answers

Therefore,

Total marks = Marks for the correct answers + Marks for the incorrect answer

-12 = 20 + (-2) × Number of incorrect answers

-12 - 20 = -2 × Number of incorrect answers

-32 / 2 = Number of incorrect answers

Number of incorrect answers = 16

• Rohan answered 16 questions incorrectly.

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.
