Answer:

t = 0.534 seconds

Step-by-step explanation:

Given that,

Amanda and Alexis live 4 miles apart.

Speed of Amanda = 3.5 mph

Speed of Alex = 4 mph

We need to find how long will it take for them to meet.

As they start walking toward each other's houses at the same rate. Their relative velocity will be :

v = 3.5 mph + 4 mph

= 7.5 mph

Let after time t they will meet.

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{4}{7.5}\\\\=0.534\ s[/tex]

Hence, after 0.534 seconds they will meet.

Answer:

The current price is Tk. 3750

Step-by-step explanation:

Given:

[tex]\%\ Increase = 20\%[/tex]

[tex]New\ Price = Tk.\ 4500[/tex]

Required

Determine the current price

Percentage increment is calculated using the following formula:

[tex]\%\ Increase = \frac{New - Old}{Old}[/tex]

In this case, we have:

[tex]\%\ Increase = \frac{New\ Price - Old\ Price}{Old\ Price}[/tex]

Substitute values for % increase and New Price

[tex]20\% = \frac{4500 - Old\ Price}{Old\ Price}[/tex]

Cross Multiply

[tex]20\% *Old\ Price= 4500 - Old\ Price[/tex]

Convert percentage to decimal

[tex]0.20*Old\ Price= 4500 - Old\ Price[/tex]

Collect Like Terms

[tex]Old\ Price+0.20*Old\ Price= 4500[/tex]

Factorize:

[tex]Old\ Price(1+0.20)= 4500[/tex]

[tex]Old\ Price(1.20)= 4500[/tex]

Solve for Old Price

[tex]Old\ Price= \frac{4500}{1.20}[/tex]

[tex]Old\ Price= 3750[/tex]

Hence, the current price is Tk. 3750

Step-by-step explanation:

Given:

The price of a share of stock in JZMobile was $74 two weeks ago.

Seven weeks ago, the price was $59 a share.

To find:

The linear equation to find the price p of a share of JZMobile w weeks from now.

Solution:

Let, p be the price of a share of JZMobile w weeks from now.

The price of a share of stock in JZMobile was $74 two weeks ago. It means, the graph of linear equation passes through (2,74).

Seven weeks ago, the price was $59 a share. It means, the graph of linear equation passes through (7,59).

The graph of linear equation passes through two points (2,74) and (7,59). So, the linear equation is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-74=\dfrac{59-74}{7-2}(x-2)[/tex]

[tex]y-74=\dfrac{-15}{5}(x-2)[/tex]

[tex]y-74=-3(x-2)[/tex]

[tex]y-74=-3x+6[/tex]

Adding 74 on both sides, we get

[tex]y=-3x+6+74[/tex]

[tex]y=-3x+80[/tex]

[tex]y=80-3x[/tex]

Therefore, the correct option is C.

Answer:

Angle I = 90 degrees

Angle J = 61 degrees

Angle K = 29 degrees

Step-by-step explanation:

Angle I is given

We know that the angles in all triangles add up to 180. Since we are given that angle I is equal to 90 degrees, we now know that angle J + angle K = 90 degrees:

(5x+26) + (2x+15) = 90

Solve for X:

7x + 41 = 90

7x = 49

x = 7

Angle J =  (5x + 26) = (5(7) + 26) = 61

Angle K = (2x + 15) = (2(7) + 15) = 29

Checking your work: 61 + 29 = 90

Answer:

[tex] m\angle I = 90\degree [/tex]

[tex] m\angle J= 61\degree [/tex]

[tex] m\angle K = 29\degree [/tex]

Step-by-step explanation:

(5x + 26)° + (2x + 15)° = 90°

(5x + 26 + 2x + 15)° = 90°

(7x + 41)° = 90°

7x + 41 = 90

7x = 90 - 41

7x = 49

x = 49/7

x = 7

[tex]m \angle \: I= 90 \degree \\ \\ m \angle \: J=(5x + 26) \degree = (5 \times 7 + 26) \degree \\ \\ m \angle \: J = (35+ 26) \degree \\ \\ m \angle \: J= 61\degree\\ \\ m \angle \: K=(2x + 15) \degree = (2 \times 7 + 15) \degree \\ \\ m \angle \: K = (14+ 15) \degree \\ \\ m \angle \: K = 29\degree[/tex]

Answer:

y= -x+8

Step-by-step explanation:

slope int. form: y=mx+b

first, we need to find the slope (m)

the two points are (2,4) and (7,-1).

to find the slope we do (y2-y1)/(x2-x1)

doing this we get -5/5=-1

now we can plug in point (2,4) and the slope into y=mx+b

doing this we get:

4=-1(2)+b

4=-2+b

b=8

now we have the equation:

y= -x+8

Answer:

The 12 egg offer.

Step-by-step explanation:

Find the unit price for each. Then make them common denominators. Like 3 eggs for 2 dollars is for 1 egg, 2/3 dollars. After getting the unit price for all of them, get the common denominators of 24. Then we see which numerator is the lowerst, since we want the lowerst price. We find 12/24, or the 12 egg offer.

Explanation:

Angle 3 and the 100 degree angle are corresponding angles. They are both in the southeast quadrant of their four-corner angle configuration. Assuming the lines that look horizontal are parallel, this would mean angle 3 is 100 degrees. Recall that corresponding angles are congruent when we have parallel lines.

Once we know that angle 3 = 100, we will use this to find angle 4.

Angles 3 and 4 add to 180. They form a straight angle or straight line.

(angle3)+(angle4) = 180

(100) + (angle4) = 180

angle4 = 180-100

angle4 = 80 degrees

What is the solution for the system below?

y = 5x - 9

y = x + 3

ANSWER : x = 3 and y = 6

The method of elimination is a method by which one of the variables is eliminated so that the remaining variables are subsequently searched for the satisfactory value.

Equation 1 : y = 5x - 9

Equation 2 : y = x + 3

x?

y?

Equation 1

y = 5x - 9

- 5x + y = - 9

5x - y = 9

Equation 2

y = x + 3

- x + y = 3

Elimination Equation 1 dan 2

5x - y = 9

- x + y = 3

--------------- +

4x = 12

x = 3

Obtained x = 3

Substitute x = 3 to equation 2

- x + y = 3

- ( 3 ) + y = 3

- 3 + y = 3

y = 3 + 3

y = 6

PROOF IF x = 3 and y = 6

5x - y = 9

5 ( 3 ) - ( 6 )

15 - 6 = 9

so the x and y values for the system are

x = 3 and y = 6
