As given by the question.
There are given that the equation of current graph:
f(x) = x^2
Now,
According to the question,
There are also given that graph left 4 units, that means
(x+4)²
Then,
Vertical stretching it by a factor of 5 units
So,
The equation will be: f(x) = 5 (x+4)²
Then,
And, shifting the graph down 2 units
So,
f(x) = 5 (x+4)² -2
Hence, the correct option is f(x) = 5 (x+4)² -2.

because we can divide 75 by 5 witch is 15, and divide 100 by 5 which is 20. you can also divide 15 and 20 by 5, 15 divided by 5 is 3 and 20 divided by 5 is 4. the 3 is the numerator and the 4 is the denominator.

Answer:
The required measure of angle 3 is 60°.
Step-by-step explanation:
We are given to find the measure of angle 3 from the figure if
m∠5 = 130° and m∠4 = 70°.
Let the measure of angle 3 be x°.
From the figure, we note that
angle 5 is an exterior angle and angles 3 and 4 are two remote interior angles of the triangle.
We know that
the measure of an exterior angle to a triangle is equal to the sum of the measures of two remote interior angles.
So, we get
Thus, the required measure of angle 3 is 60°.

How to find the sum of two vectors?
A vector exists as an object that has both a magnitude and a direction. Geometrically, we can imagine a vector as a directed line segment, whose length exists the magnitude of the vector and with an arrow suggesting the direction. The direction of the vector exists from its tail to its head.

Answer:
x = 5/3
Step-by-step explanation:
Solve for x:
7 x - 15 = -2 x
Add 2 x to both sides:
7 x + 2 x - 15 = 2 x - 2 x
2 x - 2 x = 0:
7 x + 2 x - 15 = 0
7 x + 2 x = 9 x:
9 x - 15 = 0
Add 15 to both sides:
9 x + (15 - 15) = 15
15 - 15 = 0:
9 x = 15
Divide both sides of 9 x = 15 by 9:
(9 x)/9 = 15/9
9/9 = 1:
x = 15/9
The gcd of 15 and 9 is 3, so 15/9 = (3×5)/(3×3) = 3/3×5/3 = 5/3:
