Graph the following equation y+2=3/5(x+3)

Answers

Answer 1

Answer:

Step-by-step explanation:

It is given

2x−3y=5

we can write it as

3y=2x−5

So we get

y=32x−5​

Substituting x=4 in the given equation

y=32(4)−5​

So we get

Y=38−5​

y=33​

By division we get

y=1

Substituting x=−2 in the given equation

y=32(−2)−5​

So we get

y=3−4−5​

y=3−9​

By division we get

y=−3

x 4       -2

y      1        -3

Now draw a graph using the points (4,1) and (−2,3)

Join the point through a line and find the value of y

(i) Based on the graph

consider x=4 on X-axis

Now the line joining the two points and a point on the Y-axis gives the value of y

Therefore,when x=4 the value of y=1

(ii) Based on the graph,

Consider y=3 on Y-axis

Now the line joining the two points and a point on the X-axis the value of x

Therefore, when y=3 the value of x=7

Two water balloons were launched into the air at different moments and collided. The water balloons were modeled by the quadratic functions: y=-7x2 + 26x + 6 and
y=-6x2 + 25x + 4 where y represents the height in meters and x represents the time in seconds after the launch. What is the time in seconds that the balloons
collided at the highest point?
O 1.75 seconds
O 20 seconds
O2 25 seconds
O 2.5 seconds

Answers

The time in seconds that the balloons collided at the highest point is; B: 2.0 seconds

What are quadratic equations?

We are told that the water balloons were modeled by the quadratic functions:

y = -7x² + 26x + 6 and y = -6x² + 25x + 4

where;

y = the height in meters

x = the time in seconds after the launch

The time at which they will collide has to be at the same height.

Thus;

-7x² + 26x + 6 = -6x² + 25x + 4

Rearranging this gives;

x² - x - 2 = 0

Using online quadratic equation solver gives us x = 2 or -1. We will take the positive one as x = 2.0 seconds

a

The measure of the First angle of

Second angle. The measure of the third angle
of the triangle is triple the measure of the
second angle.

Answers

Alright, lets say the measure of the 3rd angle (the smallest one) is  x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.

(x + 25) + 3x + x = 180

5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)

31 + 25 = 56o (first angle)

3 × 31 = 93o (second angle)

56 + 93 + 31 = 180

2.5 times 1,760 in steps.

Answers

Answer:

2.5 times 1760 is 4400

Step-by-step explanation:

math lol

Answer:

. We assume, that the number 1760 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 1760 is 100%, so we can write it down as 1760=100%.

4. We know, that x is 2.5% of the output value, so we can write it down as x=2.5%.

5. Now we have two simple equations:

1) 1760=100%

2) x=2.5%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

1760/x=100%/2.5%

6. Now we just have to solve the simple

equation, and we will get the solution we are looking for.

7. Solution for what is 2.5% of 1760

1760/x=100/2.5

(1760/x)*x=(100/2.5)*x - we multiply both sides of the equation by x

1760=40*x - we divide both sides of the equation by (40) to get x

1760/40=x

44=x
