write an equation in slope intercept form for the line that passes through (1,-1) and is parallel to the line described by y=2x-4

PLEASE HELP:(((((

Answers

Answer:

If 2 lines are parallel, their slopes are the same, so all we need to do is plug in the given point and slope in the equation y = mx + b and solve for b.

[tex]-1 = 2(1) + b\\\\-1 = 2 + b\\\\-3 = b[/tex]

The equation of a line in slope-intercept form that goes through (1, -1) and is parallel to the line y = 2x - 4 is [tex]y = 2x - 3[/tex].

D.

Answers

Answer:

the y-intercept is 8 and the slope is -4/3 .

Step-by-step explanation:

The y - intercept is (0, 8) and the slope is -4/3

What is the y-intercept?

"It is the point at which the graph of the function intersects the y-axis"

What is slope?

The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,

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

For given example,

We can observe that the line of best fit on this scatter plot passes though points (0, 8) and (6, 0)

Using the slope formula,

⇒ slope = (0 - 8)/(6 - 0)

⇒ slope = (-8)/6

⇒ slope = -4/3

Also, we can observe that the line of best fit on this scatter plot intersects y-axis at point (0, 8)

So, the y - intercept is (0, 8)

Therefore, the y - intercept is (0, 8) and the slope is -4/3

A cork has a mass of 3 grams and a volume of 16 cm3
. Calculate the density.

Answers

Answer:

0.1875, or 3/16

Step-by-step explanation:

The formula for density is mass/volume.

I hope this helps :)

Answer:

[tex]{\boxed {\sf \frac{3}{16} \ g/cm^3}}[/tex]

or

[tex]\boxed {\sf 0.1875 \ g/cm^3}}[/tex]

Step-by-step explanation:

Density can be found by dividing the mass by the volume.

[tex]\rho= \frac{m}{v}[/tex]

The mass of the cork is 3 grams and the volume is 16 cubic centimeters.

[tex]m= 3 \ g\\v= 16 \ cm^3[/tex]

Substitute the values into the formula.

[tex]\rho = \frac{3 \ g }{16 \ cm^3}[/tex]

Divide.

[tex]\rho=\frac {3}{16} \ g/cm^3[/tex]

[tex]\rho=0.1875 \ g/cm^3[/tex]

The density of the cork is 3/16 or 0.1875 grams per cubic centimeter.

A sports store is having a 20% off sale on skis. The original price of the ski is $560.00
The tax rate is 8.5%. What is the total cost of the skis?

Answers

Answer:

Total cost: 486.080$

Step-by-step explanation:

Original Price: 560.000$

Sale: 20%

Discount: 560.000$ * 20% = 112.000$

Discounted Price: 560.000$ - 112.000$ = 448.000$

Tax Rate: 8.5%

Tax: 448.000$ * 8.5% = 38.080$

Tax after Tax: 448.000$ + 38.080$ = 486.080$

What information can be used to compare linear relationships? Explain why.

Answers

Answer:the slope and the y intercept (you can tell there linear if the slope is the same and the y-intercepts are different).

Step-by-step explanation:

Answer:

Sample Response: Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.

Step-by-step explanation:

Two years ago Juanita bought 2 shirts for $15 and last year she bought 4 shirts for $45. Assuming the prices will increase linearly, how much will 8 shirts cost Juanita this year?

Answers

Answer:

This year, Juanita will have to use $75.

Step-by-step explanation:

Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.

Answer:

  38.5°

Step-by-step explanation:

A triangle solver can give an answer easily. The angle is 38.5°.

__

The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.

  C = arccos((a² +b² -c²)/(2ab))

Here, we have a=35, b=48, c=30, so the angle is ...

  C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°

The angle the cable makes with the pole is about 38.5°.

solve the equation or inequality.
5t - 3 (7t + 1) < 93​

Answers

Step-by-step explanation:

5t-3(7t+1) < 93

Remove the parentheses

5t-21t-3 < 93

-16t < 93+3

-16t < 96

Divide both sides by 16

-t<96/16

-t<6

t > -6

Answer: The inequality t < 6 is the correct answer.

Step-by-step explanation:

5t - 3 (7t + 1) < 93​ <--- This is the original equation.

5t + (7t + 1) - 3 < 93​ <---- Use commutative property.

16t - 3 < 93 <--- Simplify

16t - 3 + 3  < 93​ + 3 <---- Add 3 to both sides,

16t < 96 <--- Simplify and do addition.

[tex]\frac{16t}{16}[/tex] < [tex]\frac{96}{16}[/tex] <--- Divide both sides by 16.

t < 6 <--- is the answer to the inequality.

solve this equation fast please

Answers

I don’t think there’s a solution
Ok hi so I’m going to help you solve on this equation, if I solved this correctly can you please mark me as brainiest? I’d really appreciate it. Anyway let’s get started!

What we need to do is cancel both like terms on both sides of this equation which is
8=8 and you remove them.

Then you are left with -2y-3y=-5y-12

What you need to do is add -2y-3y because they are like terms

Now you have -5y

Then you put -5y=-5y-12

So you have to now cancel equal terms on both sides of this equation which were “-5y=-5y”, then you turn them into a 0

Now you are left with 0=-12

Therefore the statement is false for any value of y.

7. The lifetime of a certain brand of tires is approximately normally distributed, with a

mean of 40,000 miles and a standard deviation of 2,500 miles under normal driving conditions.

Tire wear is greatly affected by road, weather and driver conditions along with proper

maintenance of the tires. A driver who aggressively accelerates or makes quick stops, for

example, will wear out a tire much more quickly. The brand carries a warranty of 33,000 miles

under normal driving conditions, i.e., the company will replace a tire if it wears out before this

mileage limit is reached.

Answers

Answer:

0.0025551

Step-by-step explanation:

Given that:

Mean (m) = 40000

Standard deviation (s) = 2500

P(x < 33,000) :

USing the relation to obtain the standardized score (Z) :

Z = (x - m) / s

Z = (33000 - 40000) / 2500 = - 2.8

p(Z < -2.8) = 0.0025551 ( Z probability calculator)

Probability of Tyre wagering out before mileage limit is reached = 0.0025551
