Answer:
y ≥ 1/4x + 2
Step-by-step explanation:
The line is solid, and the shading is above it, so the inequality will have a form similar to ...
y ≥ [the boundary line]
The y-intercept is y = 2, and the slope is 1 unit up for 4 units right, so 1/4. In slope-intercept form, the equation of the boundary line is ...
y = mx + b . . . . . . for slope m and y-intercept b
This boundary line has equation ...
y = 1/4x + 2
So, the inequality is ...
y ≥ 1/4x + 2
1/4 I think bc there are 2 pairs of each and I total there are four earrings solo
Answer:
The equation that describes the amount of mass left after a time t of a radioactive isotope is the following:
where
is the mass of the sample at t = 0
is the half-life of the sample
For the element X in this problem,
We want to find the time t at which
So we need to re-arrange the equation making t the subject:
Step-by-step explanation:
Answer:
It would be True
Step-by-step explanation:
2+5x = -8
SUBTACT 2 on both sides and it would look like this:
5x = -8 - (2)
5X= -10
then DIVIDE 5 both side to get "X" ALONE,
x= -10/5
then divide -10 with 5
equal to:
x = -2
(-3, 1) y = 2/5x - 4
x₁ y₁ slope (m) = 2/5x
Since the equation we are looking for is perpendicular to y = 2/5x - 4, we need to find the opposite reciprocal slope. We have to flip the slope upside down and turn it negative.
2/5 ⇒ 5/2 ⇒ -5/2
So far, we have the equation y = -5/2.
Now, we need to find the y intercept by plugging in the given point into point slope form, which is...
y - y₁ = m(x - x₁)
The subscripts in the y and x are just the x and y in (-3,1). They are just placeholders, not exponents.
y - 1 = -5/2(x + 3)
y - 1 = -5/2x - 15/2
+ 1 + 1
------------------------------
y = -5/2x - 13/2 ⇒ final equation
