How many solutions does the equation −4y + 4y + 2 = 2 have?

timofeeve [1]

−4y + 4y + 2 = 2
 −4y + 4y = 2 -2
0 = 0 .

Anytime you have this format of 0 = 0, just know there are infinitely many.

Any number as a value of y can satisfy the equation.

Jen knows that (-1, 41) and (5, 41) lie on a parabola defined by the equation y=4x^2-16x+21. How can I find the coordinates of t

andreyandreev [35.5K]

The vertex is at (2, 5).

To find the vertex, we first find the axis of symmetry; this is given by

x = -b/2a

For our equation, b = -16 and a = 4:
x = -(-16)/2(4) = 16/8 = 2

We substitute this back into our equation:
y = 4(2)² - 16(2) + 21 = 4(4) - 32 + 21 = 5

Therefore the vertex is at (2, 5).

2) As part of traffic accident investigations, the speed of a car involved can be approximately determined by checking actual sk

dezoksy [38]

a) The speed of car was 60 mph.

b) The speed of car was 45 mph.

Step-by-step explanation:

Given,

a = actual skid marks

p = test skid marks

Formula;

$s=30*\sqrt{\frac{a}{p}}\\$

a) a = 144 feet, p = 36 feet

Putting in formula;

$s = 30*\sqrt{\frac{144}{36}}\\\\s=30*\sqrt{4}\\\\s=30*2\\\\s=60$

The speed of car was 60 mph.

b) a = 153 feet, p = 68 feet

Putting in formula;

$s=30*\sqrt{\frac{153}{68}}\\\\s=30*\sqrt{2.25}\\\\s=30*1.5\\\\s=45$

The speed of car was 45 mph.
