From the first equation we get
y=4x-15
put the value of y in the second equation
3x+2(4x-15)= -8
3x+8x-30= -8
11x=22
x=2
now put x=2 in any one eqn , say in first
4(2)-y=15
8-y=15
-y=7
y=-7
hope you understand!
The fundamental theorem of calculus tells us that
So we have
and
Answer:
a triangle with a right angle
Step-by-step explanation:
Answer:
<em>b = 50√c</em>
Step-by-step explanation:
If b varies directly as the square root of c, this is expressed as;
b∝√c
b = k√c
k is the constant of proportionality
Given b = 100 and c = 4
100 = k√4
100 = 2k
k = 100/2
k = 50
Substitute k = 50 into the original expression:
Recall that: b = k√c
b = 50√c
<em>hence equation that can be used to find other combinations of b and c is b = 50√c</em>
