Can you help me with this please??

Answer:

B. y= 2x–15

Step-by-step explanation:

The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15

"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)

(8, 1) and (10, 5)

x in the first bracket is 8 and x in the second bracket is 10.

y in the first bracket is 1 and y in the second bracket is 5.

When this equation is applied to find the value for y we get:

y= 2x-15

y= 2(8)-15

y= 16-15

y= 1

y= 2x-15

y= 2(10)-15

y= 20-15

y= 5

We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)

Answer:

There is no real solution

Step-by-step explanation:

If you are finding the square root of a number, it cannot be negative. No number can be multiplied by itself to get a negative number. Negative numbers multiplied with themselves make a positive number. Positive numbers are obviously going to stay positive. Therefore there is no square root of -9

Answer:

C. 4123.

Step-by-step explanation:

We calculate the cost of a gram of cat food for each package.

Pack 1: Cost of 1 gram = total cost / number of grams

= 39.99 / (24 * 250)

= $0.00665 '

Pack 2: The cost is  24.99 / (12 * 300)

= $0.00694.

In a similar way

Pack 3:  The cost is $ 0.0722

Pack 4: The cost is $0.00642 .

So the answer is

4123

Answer:

y = 1/4x - 1.75

Step-by-step explanation:

standard form is y = mx + b

to get m you need to calculate the slope between the given points

m= (y1-y2)/(x1-x2)

m = (-1 - (-3))/(3 - (-5)) = 2/8 = 1/4

now you need to find the constant b by plugging in one of your points

y = 1/4x + b

-1 = 1/4(3) + b

b = -1 - (3/4)

b = -7/4 or -1.75

Answer:

0 = x - 4y - 7

Step-by-step explanation:

Moving from (-5, -3) to (3, -1), we see that x (the run) increases by 8 and y (the rise) incrases by 2.  Thus, the slope of the line connecting these two points is m = rise / run = 2/8, or 1/4.

Use the slope-intercept form of the equation of a straight line first:

y = mx + b becomes          -1 = (1/4)(3) + b, or (after multiplying all three terms

                                           by 4)  -4 = 3 + 4b.  Then 4b = -7, and b = -7/4.

Then the desired equation is    y  = (1/4)x - 7/4, or

4y = x - 7, or

0 = x - 4y - 7.  This is the desired equation in standard form.

Answer:

b) ∠4 = m∠U + m∠L

Step-by-step explanation:

The volume of the cylinder is approximately 351.9 cubic centimeters.

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

We have,

The volume of a cylinder can be calculated using the formula:

V = πr²h,

where r is the radius of the base and h is the height.

Since the base diameter is given as 8 centimeters, the radius is half of that or 4 centimeters.

Substituting these values into the formula, we get:

V = π (4 cm)² (7 cm)

V ≈ 351.86 cm³

Rounding this answer to the nearest tenth gives a final answer of V ≈ 351.9 cm^3.

Therefore,

The volume of the cylinder is approximately 351.9 cubic centimeters.

Answer:

Option B

Step-by-step explanation:

When all options are graphed along withe the equation in the question,

[tex]y=-4x[/tex] does not intercept with [tex]y=-4x-12[/tex].

This means that y=-4x and y=-4x-12 will have no solution.

Option B should be the correct answer.

Work Shown:

The diameter is 60 feet, so the radius is half that at 60/2 = 30 feet.

Plug r = 30 into the formula below and simplify

V = (4/3)*pi*r^3

V = (4/3)*pi*(30)^3

V = (4/3)*pi*27000

V = (4/3)*27000*pi

V = 36000pi

Answer:

C. Brandon. He has a 0.63 probability of attending both activities.

Step-by-step explanation:

                 Probability of attending     Probability of attending

                 the Saturday activity          the Sunday activity

Aisha                     0.90                                  0.68

Brandon                 0.71                                  0.89

Given that attendance at one activity is independent of  attendance at the other, the probability that Aisha attends both activities is: 0.9*0.68 = 0.61, and the probability that Brandon attends both activities is: 0.71*0.89 = 0.63

Brandon has a 0.63 probability of attending both activities.

The correct option is (C).

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

                Probability of attending     Probability of attending

                            ( Saturday)                    ( Sunday )

Aisha                     0.90                                  0.68

Brandon                 0.71                                  0.89

As,  attendance at one activity is independent of attendance at the other activity.

P( Aisha attends both activities)

=0.9*0.68

= 0.61,

P(Brandon attends both activities)

= 0.71*0.89

= 0.63

Hence, Brandon. He has a 0.63 probability of attending both activities.

Answer:

He need to cover 275 miles for same cost for both plans

Step-by-step explanation:

Let x be the no. of miles

Case 1 :

Initial fee = $38

Additional cost of 1 mile = 0.13

Additional cost of x miles = 0.13x

So, total cost = 38+0.13x

Case 2 :

Initial fee = $49

Additional cost of 1 mile = 0.09

Additional cost of x miles = 0.09x

So, total cost = 49+0.09x

Now we are supposed to find amount of driving do the two plans cost the same

So, 38+0.13x=49+0.09x

0.13x-0.09x=49-38

0.04x=11

[tex]x=\frac{11}{0.04}[/tex]

x=275

Hence he need to cover 275 miles for same cost for both plans

Answer:

6900000 + (6900000 * x) = 7400000

This equation is telling us 6900000 plus 6900000 times a specific percent will get you 7400000, which is what you want.

6900000 + (6900000 * x) = 7400000

6900000 + 6900000x = 7400000

Subtract 6900000 from both sides.

6900000x = 500000

Divide both sides by 6900000

x = 0.0724637681, or .07 when rounded to the nearest tenth.

convert .07 to a percentage by moving the decimal point two places to the right.

.07 = 7%
