Answer:
This point is not on the line, NOT TRUE
Step-by-step explanation:
The equation of the line is written in the slope-intercept form,
y = mx + b
where m represents the slope
b represents the y-intercept
where the format of a point is (x, y)
<u>Given:</u> y = 7x (6/7, -1/4)
we can plug in the point (6/7, -1/4)
-1/4 = 7(6/7)
-1/4 = 6
<em>-1/4 does not equal 6 so this point is not on the line</em>

Answer:
Step-by-step explanation:
y + 4 = -2(x - 5)
y + 4 = -2x + 10
y = -2x + 6
Answer:
Perimeter of is .
Explanation:
Given: In , , and AD= 8cm.
In
Sum of the measure of the angles of triangles is 180 degree.
or
Simplify:
∵ AD= 8cm and to calculate the length of CD we use tangent ratio i.e,
then;
or
Simplify:
cm.
Also, find the length of AC, we use sine ratio i.e, .
Then,
or
On simplify:
cm.
Now, in triangle ABC;
, then
[Sum of the measure of the angles in the triangle is 180 degree]
To calculate the length of BC;
[∴ ]
therefore,
or
Simplify:
cm.
Using Pythagoras theorem in triangle ACB;
Let BD be x cm
AB = 8+x cm , AC = 16 cm and cm
or
or
Simplify:
x=24 cm
Therefore, the length of AB = 8+x= 8+24=32 cm
Perimeter(P) of triangle ABC is equal to the sum of the sides of the triangle.
⇒ P= AB+BC+AC = cm
B.)greater than five but less than six
30 because 18 and the plain goes into 12 which is 30
