Given y = 3x + 6, we find the x-intercept by setting y = 0 and solving the resulting equation for x: 0 = 3x + 6, or 3x = -6, or x = -2. The x - intercept is (-2,0).

Find the y-intercept by setting x = 0: y = 3(0) + 6 = 6. The y-int. is (0,6).

y = 3x + 6 slope intercept form

change to standard form

-3x + y = 6

to find x-intercept substitute y for zero

-3x + 0 = 6

-3x/-3 = 6/-3

x = -2 so the x-intercept is -2

-3x + y = 6

to find y-intercept substitute x for zero

-3(0) + y = 6

0 + y = 6

y = 6 so the y-intercept is 6

also in y= mx + b (the slope intercept form) b represents the y-intercept.

y = 3x + 6 b is the 6 so 6 is the y-intercept

The ordered pairs: y-intercept (0,6) x-intercept (-2,0)

Does anyone know the answer

Answer:

Both angles B and C are equal to 40°

Step-by-step explanation:

The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.

$2x+10=3x-5\\10=x-5\\15=x$

Now we are going to plug x back into each expression to solve for angles B and C.

Angle B

$2x+10$ ⇒ $2(15)+10=40$

Angle C

$3x-5$ ⇒ $3(15)-5=40$

Both angles B and C are equal to 40°

the coordinate plate shows the location of vijays house. the location of huang's house is a reflection of the location of vijays

harina [27]

Answer:

The location of Huang's house is (5,2)

Step-by-step explanation

We can see in the picture that

Elm street can be defines as x-axis

Oak street cab be defines as y-axis

A reflection can be defined as flipping an object over the line of reflection. The original object is called pre-image, and the newly formed reflection is called image. Both the object and reflection have the same size and shape, and same distance from the line of reflection.

E.g when reflecting an object across x-axis , the x-coordinate of the object remains the same in the reflection, but the sign of y-coordinate is changed.

Similarly, when reflecting an object across y-axis, y-coordinate of the object remains the same in reflection, but the sign of x-coordinate is changes.

In the question, the location of Vijay's house is given by coordinates (-5,2)

As we can consider Oak street as y-axis, and we have to reflect the house across Oak street, then the reflection will have same y-coordinates, but the sign of x coordinate will change.

Which means the location of Huang's house is (5,2)
