Answer:
Y = 27
Step-by-step explanation:
To find the the value of y when x = 4 simply substitute the given value of x
into the equation and solve for y
Equation given: y - 3x = 15
x = 4 * substitute 4 for x in given equation *
y - 3(4) = 15
Now solve for y
simplify multiplication
y - 12 = 15
Add 12 to both sides
y - 12 + 12 = 15 + 12
y = 27
So we can conclude that when x = 4 y = 27
Answer:
y – 1= Three-halves(x + 3)
Step-by-step explanation:
line goes through (-2, -4) and (2, 2)
goes through (-3, 1)
slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/2
1 = (3/2)*-3 + b
1 = -9/2 + b
b = 1 + 9/2 = 11/2 = 5.5
y = (3/2)*x + 11/2
(y - 1) = (3/2)(x + 3)
Answer:
168 cm³
Step-by-step explanation:
The base of the prism is a right triangle whose hypotenuse is 10 cm and one other side is 6 cm.
So, the third side of the triangle =
cm.
{Since we have applied the Pythagoras theorem.}
Hence, the area of the base triangle is
cm².
Therefore, the volume of the prism is =
cm³ {Since volume of a prism is given by ( Area of the base triangle ) × ( Height of the prism )}
