What is the solution to the system of linear equations graphed below?

Answer:

Slope: 1

Y-Intercept: 3

Equation of the line: y=x+3

Step-by-step explanation:

1. Slope

Get two random points (eg. 0,3; -3,0)

x1-x2/y1-y2

0-(-3)/3-0

0+3/3

3/3=1

2. Y-intercept

The value of x when y=0

3. Equation of the line

y= mx+b

m= slope

b= y-intercept

y=1x+3

y=x+3

Answer:

Her mistake is that she should plot the point (0, 5) first, not (1, -3)

Step-by-step explanation:

First I simplified the equation given.

y - 3 = 2 (x + 1)

y - 3 = 2x + 2

  +3         +3

y = 2x + 5

Since 5 is our y-intercept we would want to graph that first, which would be (0, 5) as a point.

Answer:

10(7 + 6s) = 70 + 60s

Step-by-step explanation:

10(7 + 6s)

Distribute the 10 in the parenthesis. When distributing, multiply the number by every term in the parenthesis.

10 * 7 + 10 * 6s

Multiply.

70 + 60s

Answer:

10(7)+10(6s) which equals 70+60s

Given options:

Choice A

Answer:

A: Second option

B: 18%

Step-by-step explanation:

PART A

The second option

0.40c(0.15) + 0.60c(0.20)

If we have 40% men, and 15% of them are advanced

we can say 40% x 15% x c which is the same as 0.40 x 0.15 x c

Same thing for the women

0.60 x 0.20 x c

PART B

0.40c(0.15) + 0.60c(0.20)

= 0.06c + 0.12c

= 0.18c  which is the same as  18% of c

The perimeter of the triangle RON is the sum of the side lengths

The perimeter of the triangle is 15 units

From the question, we have:

ON = 5 units

Side lengths ON and OR are radii of the circle O.

So, we have:

OR = ON = 5 units

The chord RN has a length of 5 units.

So, the perimeter of the triangle is:

P = OR + ON + RN

This gives

P = 5 + 5 + 5

Evaluate

P = 15 units

Hence, the perimeter of the triangle is 15 units

Answer:

RON = 15.0

Step-by-step explanation:

Just did the test and got it right.

But question was I the only one who thought of Ron Weasley

Step-by-step explanation:

you have to be careful with the precise notation of terms and expressions.

you keep using only -7 for everything.

i suspect you mean 7 and -7, right ?

if that is correct, then just remember this :

on a number line the positive values are on the right, and the negative values on the left.

in fact, the further right you go, the larger the number gets. and the further left you go, the smaller (or lower) the number gets.

e.g. -7 is smaller than -6.

and so, -7 would be to the left of 7, because -7 < 7.

or vice versa :

7 would be to the right of -7, because 7 > -7

Answer:

the anwer is a triangle as it is shown below.

Answer:

10.14π

Step-by-step explanation:

First we have to work backwards. We know the forumla for circumference is pi x diameter. So we have to work backwards. 20 divided by pi is 6.37. So thats our diameter. Now that we that we can put it into our forumla for area. A= π x R^2.

The raidus is half of the diamater so 6.37/2. Which equals 3.185. Now we that into our formula. A= π x 3.185^2. Now we keep simplyifying the equation. 3.185^2=10.14. So now we have A=10.14π

The inequality x -4 > 2 uses a greater than symbol

All numbers lesser or equal to 6 are not a solution of the inequality x -4 > 2

The inequality is given as:

x -4 > 2

Add 4 to both sides of the inequality

x - 4 + 4 > 2 + 4

Evaluate the sum

x > 6

The above means that only numbers greater than 6 are in the solution of the inequality.

301.6 cubic meters

A cylinder is a shape with straight sides with circular or oval cross-sections. We know that the cylinder in the question must be a circular cylinder due to its radius description. 

Volume Formula

A circular cylinder has a volume of [tex]V=\pi r^2h[/tex]. In this equation, V is the volume, r is the radius, and h is the height. The question tells us that r=4m and h=6m. So, we can plug these values into the formula.

Solving for Volume

To solve plug the values into the formula and rewrite the equation.

Next, apply the exponents.

Then, multiply the constants.

Finally, multiply the remaining terms. Remember to use the pi button on the calculator and not an estimation to get a more exact value.

Make sure your answer is rounded to the correct digit. This means that the volume must be 301.6 cubic meters.

well, your observation is correct, for the form

if the coefficients are the of x² and y² are different and the same sign then we have an ellipse, hmmm I usually see a circle as an ellipse with equal major and minor axes, because is basically just that.

However, the rational form you have is that of an ellipse indeed, we can change it about to the form above and you'll see it so.

Just bear in mind that for the rational form for conics

if both fractions are positive and their denominator different, is an ellipse

if both fractions are positive and their denominator equal, is a circle

if one of the fractions is negative, then we have a hyperbola, and on a hyperbola the traverse axis is always the denominator with the positive fraction, so if the denominator is under the "x" fraction, then the traverse axis is horizontal, if under the "y" fraction, then vertical.

based on that fraction, is an ellipse with a center at (2 , -5).

now, the larger denominator is 29 and it's under the "y" variable, that means the major axis is in the direction of the y-axis, so is a vertical ellipse if you wish.     Check the picture below.
