Answer:
3
Step-by-step explanation:
f(x)=a*b^x - is a formula of exponential function
As we know the point (x=0; y=3) lies at the function's graph.
So we have to put in formula f(x)=a*b^x x=0 f(x)=y=3
3=a*b^0 (b^0=1) => 3=a*1 => 3=a
I think it may be: 0.66666666666
I only looked it up on the internet.
Answer:
angle 3 = 79 degree
Step-by-step explanation:
given:
angle 1 = 98 degree
angle 2 : 19 degree
angle 3 =?
angle 2 + angle 3 =angle 1 (sum of two interior angle opposite angles is equal to the exterior angle formed)
19 + angle 3 = 98
angle 3 = 98 - 19
angle 3 = 79 degree
Y = 6x - 11
-2x - 3y = -7
Let's use substitution:
-2x - 3y = -7
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-20x + 33 = -7
-20x = -40
x = 2
----
y = 6x - 11
y = 6(2) - 11
y = 12 - 11
y = 1
----
y = 6x - 11 => 1 ? 6(2) - 11 => 1 = 12 - 11 <--True
-2x - 3y = -7 => -2(2) - 3(1) ? -7 => -4 - 3 = -7 <--True
Answer:
x = 2
y = 1
Hope this helps!
