4•45= 180
what is the inverse of -9x+2
Step-by-step explanation:
so,
y = -9x + 2
now we need to transform this equation that actually x is calculated out of y.
and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.
so,
y = -9x + 2
y - 2 = -9x
x = -(y - 2)/9 = (-y + 2)/9
=> for a formal function definition
y = (-x + 2)/9

side lengths for a triangle?
A. 9, 4,8
B. 14, 7,6
C. 3, 8, 1
The only set of side lengths that can form a triangle is 9, 4, 8.
Option A is the correct answer.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Let's check if each of the given sets of side lengths satisfies this condition:
A.
9, 4, 8
9 + 4 > 8 ✓
9 + 8 > 4 ✓
4 + 8 > 9 ✓
All three inequalities are true, so these side lengths can form a triangle.
B.
14, 7, 6
14 + 7 > 6 ✓
14 + 6 > 7 ✓
7 + 6 > 14 ✗
The last inequality is false, so these side lengths cannot form a triangle.
C.
3, 8, 1
3 + 8 > 1 ✓
3 + 1 > 8 ✗
8 + 1 > 3 ✓
The second inequality is false, so these side lengths cannot form a triangle.
Therefore,
The only set of side lengths that can form a triangle is A. 9, 4, 8.

A school counts the number of students taking AMDM and find 225 students taking AMDM. They also count the number of students taking Physics and find 248 students taking the Physics. When they compare the two lists they find 98 student taking AMDM and Physics. What is the probability of a student taking AMDM given they are taking Physics. (Answer in decimal form rounded to the thousandth)
The probability of a student taking AMDM given they are taking Physics is 39.51%.
Since a school counts the number of students taking AMDM and find 225 students taking AMDM, and they also count the number of students taking Physics and find 248 students taking the Physics, and when they compare the two lists they find 98 student taking AMDM and Physics, to determine what is the probability of a student taking AMDM given they are taking Physics, the following cross multiplication calculation must be performed:
248 = 100 98 = X 98 x 100/248 = X 9800/248 = X 39.51 = X
Therefore, the probability of a student taking AMDM given they are taking Physics is 39.51%.

Write an equation (any form) for the quadratic graphed below:
Answer:
Quadratic equation in vertex form: y = 2(x + 3)²+ 0
Step-by-step explanation:
The vertex form of a quadratic equation is:
y = a (x - h)² + k where:
The value of a determines that the graph opens up or down. If a is positive, the graph opens up. The value of a also makes the parent function wider or narrower.
The vertex of the given parabola occurs at point (h, k) where the parabola intersects the axis of symmetry, x = h. It is also determines whether it is either the maximum or minimum point on the graph.
The quadratic equation of the graph in vertex form is: y = 2(x + 3)²+ 0
where:
a = 2
vertex (minimum point) = (-3, 0)
axis of symmetry: x = -3
