1)
2a - 3bc = -9
2a = -9 + 3bc
a = -9/2 + 3bc/2
2)
Reciprocal of -2/3 is -3/2
3)
reciprocal of -1 is -1/1 or -1
Hope this helps :)
Answer:
Option (D) is correct.
Step-by-step explanation:
In a triangle BCD , with b, c, d as the sides of triangle.
Sine rule states when we we divide side b by the sine of angle B then it is equal to side c divided by the sine of angle C and also equal to side d divided by the sine of angle D.
Using Sine rule,
Consider the first and third ratio,
Substitute the values of d = 3 , b= 5 and ∠D=25°
Thus, Measure of angle B is 45 and 135 as sinB is positive is first and 2nd quadrant.
Thus, option (D) is correct.
divide total cost by amount
5 / 4 = 1.25
unit cost = $1.25 per quart
Answer:
B im almost 100% sure, the 3 is where it starts on the Y axis so its based off the 2x which goes up 2 over to the right one, if it goes on a downward slope like the bottom two then that means its a negative equation.
Answer:
Part 1)
Part 2) The length of the base is
Step-by-step explanation:
Part 1) Which equation would be help solve the following problem?
Let
x----> the length of the base of a triangle
y----> the height of a triangle
we know that
The area of a triangle is
so
------> equation A
-----> equation B
Substitute equation B in equation A
Part 2) Find the length of the base
we have
solve for x
Solve the quadratic equation by graphing
The solution is
see the attached figure
