The graph of the linear equation:

y - 4 = (2/3)*(x + 2)

Can be seen on the image at the end.

Here we have the following linear equation:

y - 4 = (2/3)*(x + 2)

Isolating y, we get:

y = (2/3)*(x + 2) + 4

To graph the line, we just need to evaluate it in two different values of x so we get two points, once we get the points, we can graph them on a coordinate axis and then connect them with a line.

If we use x = 1 we get:

y = (2/3)*(1 + 2) + 4

y = (2/3)*3 + 4

y = 2 + 4 = 6

y = 6

Then we have the point (1, 6)

if x = 4 then:

y = (2/3)*(4 + 2) + 4

y = (2/3)*6 + 4

y = 4 + 4 = 8

So we have the point (4, 8)

Then the graph of the linear equation is the one you can see below:

Answer:

x = 3.5 hours

y = 1.5 hours

Step-by-step explanation:

There are two unknowns, x and y, both in umits of hours.  We need at least two equations before we start trying to solve this with substitution.  Looking at the information, this should be possible.

First, we know that Speed x Time = Distance.  

The distance covered by the cyclyst would be the sum of (12km/h)*x and (16km/h)*y, where x is the time, in hours, for the slower speed and y for the faster.  Together, the student travels 66 km.

The total distance of 66 km would be comprised of the two distances 12x and 16y:

 12x + 16y = 66 km  

For the second equation, we know that the total time is 5 hours.  That would be the sum of x and y:

 x + y = 5 hours

We now have 2 equations, so we stand a good chance of finding the answer.  Pick one of the equations and isolate one of the variables to one side.  Let's choose x + y = 5 hours, since that is easy to rearrange:

     x = 5-y

Now take the first equation and substitute the definition of x from above (5-y):

12x + 16y = 66

12(5-y) + 16y = 66

60-12y + 16y = 66

4y = 66-60

4y = 6

y = (6/4) or 1.5 h

The time spent at 16 km/h was 1.5 hours.

Use this value of y in either equation to find x.  Let's use x+y=5, since that will be easier:

x+y = 5 for y = 1.5

x+1.5 = 5

x = 3.5h

The time spent at 12 km/h was 3.5 hours

Step-by-step explanation:

remember, the sum of all angles in a triangle is always 180°.

now let's consider the white, "cut-out" triangle on the left side.

the purple one angles at the top and bottom corner are 45°.

the withe outer angles at the same corners (they are the inner angles for the white triangle) are complementary angles (together they have 90°) to the purple ones, because due to the equal angles at the top and bottom we know the connection between the 2 45° angles (the white baseline) is at a 90° angle to the 45° to 135° sides.

so the 2 baseline angles of the left white triangle are also 45° (45+45 = 90).

and that means that the third white angle is

180 - 45 - 45 = 90°.

and because a full circle around the 3x° point must have 360° (as any full circle), we know that both angles (90° and 3x°) together are 360°.

360 = 90 + 3x

270 = 3x

x = 90°

3x = 270°

Lines do not end, so there can not be an end behavior.

What is straight line?

Y = mx + c is the general equation for a straight line, where m denotes the line's slope and c the y-intercept. It is the version of the equation for a straight line that is used most frequently in geometry. There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

The equation of the right sideline is y+8 =  [tex]\frac{4+8}{2-0}[/tex] (x-0)

y+8 = 6(x -0)

y =6x - 8

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Answer: length C to A is .001 and c to b is 0.03 and b to a is 0.04

Step-by-step explanation:

a.  I would rather compound annually at 5 % interest

b.  I would increase the simple interest rate if i were to change my answer

Since you have $200 to invest for 10 years, would you rather invest your money in a bank that pays 7% simple interest or 5% interest compounded annually, we need to determine the amount of each type of interest after 10 years.

Since  you have $200 to invest for 10 years at  7% simple interest, using the simple interest formula for the amount, we have

A = P(1 + rt) where

Substituting the values of the variables into the equation, we have

A = P(1 + rt)

A = 200(1 + 0.07 × 10)

A = 200(1 + 0.7)

A = 200(1.7)

A = 340

Also, since  you have $200 to invest for 10 years at  5% interest compounded annually, using the compound interest formula for the amount, we have

A' = P(1 + r)ⁿ where

Substituting the values of the variables into the equation, we have

A' = P(1 + r)ⁿ

A' = 200(1 + 0.07)¹⁰

A' = 200(1.07)¹⁰

A' = 200(1.9672)

A' = 393.43

Since A' = $393.43 > A = $340, i would rather compound annually at 5 % interest

The sum of the numerator and denominator of the decimal is found as 111.

As for the given question;

The decimal number is given as;

0.12 bar

Decimal to fraction conversion

100(0.12 bar) = 12(0.12 bar)

99.(0.12bar) = 100(0.12bar) - (0.12 bar)

99.(0.12bar) = 12 × 0.12bar - 0.12bar

99.(0.12bar) = 12

0.12 bar = 12/99 (lowest fraction)

Thus, in the result the numerator is found as 12 and the denominator is found as 99.

Step-by-step explanation:

the flight path of a rocket or a thrown object is a parabola as described by the function.

h(t) = -16t² + 40t + 7

the negative sign of the prime coefficient (-16) tells us that the parabola opens downwards, and that the vertex as the extreme point of the parabola is a maximum.

we get the extreme point of a curve by finding the zero solution of the first derivative of the function.

and the extreme value itself by using that value in the original equation and calculate the result.

h'(t) = -32t + 40

0 = -32t + 40

32t = 40

t = 40/32 = 5/4 = 1.25 seconds

h(5/4) = -16×(5/4)² + 40×5/4 + 7 =

= -16×25/16 + 10×5 + 7 =
