find the equation of a straight line passing through the point (1,2) and making an intercept of 3 on the positive y-axis.​

Answers

Answer 1
Given: the points (1|2) and (0|3) lie on the line.

Question: equation of the line.

Solution:

General equation of a line: y = kx+d,

whereby:

the point (y|x) lies on the line
When x = 0, y = d
The point (0|3) says that d = 3.

So far, the equation is y = kx +3 ……… (1)

Inserting the point (1|2) into (1):

2 = k(1) + 3 => 2–3=k => -1 = k

Putting k into (1):

y = -1x + 3 => y = -x + 3 => y = 3 - x

Answer:

y = 3 - x

Answers

1. 2x + 20 + x + 10 + 2x - 5 = 180
5x + 25 = 180
5x = 155
x = 31 degrees

2. A = x + 10
A = 31 + 10
A = 41 degrees

3. B = 2x + 20
B = 62 + 20
B = 82 degrees

4. C = 2x - 5
C = 62 - 5
C = 57 degrees

Answer:

∠A =  41

∠B = 82

∠C  = 57

Step-by-step explanation:

Sum of all the angles of triangle = 180

x + 10 + 2x -5 + 2x + 20 = 180

x +2x +2x + 10 - 5 +20 = 180     {Combine like terms}

5x + 25 = 180

         5x = 180 - 25

         5x =155

          x = 155/5

         x = 31

∠A = x + 10 = 31 + 10 = 41

∠B = 2x +20 = 2*31 + 20 = 62 + 20 = 82

∠C = 2x - 5 = 2*31 - 5 = 62 - 5 = 57

y = x^2 + 4x - 5
I need to know if it is maximum or minimum , the axis of symmetry , the vertex , domain , range ​

Answers

Answer:

i honestly have no idea

Step-by-step explanation:

Answer:

The coefficient of x^2 is positive (here it is 1) so we have a minimum.

Rearrange it to the form (x-a)^2 + b:

(x+2)^2 - 4 - 5 = (x+2)^2-9

This means the minimum, or vertex, is at (-2,-9)

Parabolas are symmetrical horizontally, so the axis of symmetry is the vertical line at the minimum, which is x = -2

The domain is all numbers

The range is y >= -9

Answers

Answer:

R'(-5, -1) S'(-1, -1) T'(-1,-6)

Step-by-step explanation:

because the triangle is moving to the left, you subtract the number of units from the x coordinates of each vertex of the triangle. becasue the triangle is moving down, you subtract the number of units moved down from the y coordinates of each vertex.

The volume of a cuboid is 189cm3.
The length is 7cm and the width is 9cm.
Work out the height of the cuboid.

Answers

The height of the cuboid is 3cm. 7x9x3 = 189
Volume = Length x Width x Height

Volume of cuboid:
Let h cm be the height of the cuboid.

7 x 9 x h = 189

63h = 189

h = 189/63

h = 3


The height of the cuboid is 3 cm.
