To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
Answer:
Volume is measured in "cubic" units.
Step-by-step explanation:
Answer:
y ≤ 0
Step-by-step explanation:
The circle isn't shaded in so the value is less than and y
cause below the line (or 0,0) the graph is shaded
Answer:
-1 and -11 are x-intercepts, y-intercept = 11.
Step-by-step explanation:
given function: f(x) = x^2 + 12x + 11.
- x-intercepts: value of the function when f(x) is zero.
so, 0= x^2 + 12x + 11.
write 12x as 11x+x,
x^2 + x+11x + 11=0
common terms,
0 = (x + 1)(x+ 11)
- so, -1 and -11 are x-intercepts. because, when we substitute these as x values, the f(x) will be zero.
- y-intercept: value of the function f(x) when x=0 i.e, f(0).
so, y-intercept= 0+0+11 = 11.
We can use the Sine Law:
a / sin A = b / sin B
16 / sin 22° = 25 / sin B
16 / 0.3746 = 25 / sin B
sin B = 25 · 0.3746 / 16
sin B = 0.5853
∠B = sin^(-1) 0.5853
∠B = 35.83° ≈ 35.8°
Answer: b. 35.8°
