Answer:
-4.2
Step-by-step explanation:
The linear term is missing from the quadratic, which means it is symmetrical about the vertical line x=0. For each x-intercept greater than 0, another is its opposite. The opposite of 4.2 is -4.2
The other x-intercept is -4.2.
__
Consider the parent function ...
y = x^2
which is symmetrical about the y-axis.
Transforming it to ax^2 +k causes it to be scaled vertically by a factor of 'a', and shifted vertically up k units. Neither of these transformations affects the horizontal position of the curve, so it remains symmetrical about the y-axis. Attached is one example of a quadratic of this form with an x-intercept of 4.2.

Two trains leave stations 360 miles apart at the same time and travel toward each other. One train travels at 110 miles per hour while the other travels at 90 miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.
Answers
train A speed = 95 mph
train B speed = 105 mph
they are travelling towards each other
so effective speed = 200 mph.
distance = 360 miles
t= d/r
t=360/200
time = 1.8 hours they will meet

Answer:
B) 24
Step-by-step explanation:
The area of the rectangle is 48 units (8 x 6).
The base of the is 6 units and the height is 8 units. The formula for the are of a triangle is A = [tex]\frac{1}{2}[/tex]bh.
b = base
h = height
A = [tex]\frac{1}{2}[/tex](6)(8)
A = 24
Answer:
[tex]24[/tex]
Step-by-step explanation:
If the area of a rectangle is bh, and the area of a triangle is bh/2, then a triangle's area is half a rectangle's area. Hence, if the area of the rectangle is 48, the area of the triangle is half of 48, or 24.

Consider the diagram.
Which equations are true? Select all true equations.
Answers
Answer:
Sum of angles of a triangle is 180, so x + y + w = 180
Straight angle is 180 , so y + z = 180
From the first 2 conditions :
=>x + y +w = y + z
=> x + w = z
Option 1, 2, 5
The equations which are true are given by,
w + x + y = 180w + x + y = 180y + z = w + x + yw + x + y = 180y + z = w + x + yw + x = z What is an Equation?Equation is a mathematical relation between more than one variable, number or mathematical quantities involving mathematical operations using equal sign in between them.
From angle sum property of triangle says that the sum of all interrior angles of a triangle is 180.
Here all interrior angles of triangle are x,y,w
So, x+y+w = 180
Hence first option is correct.
Again the exterrior angle of a triangle is equal to the sum of the opposite two interrior angles.
here exterrior angle is z and opposite two interrior of z are x,w
So, w+x = z
Hence last option is correct.
Again y+z = y+w+x
so second option is also true.
Hence correct options or equations are given by:
w + x + y = 180w + x + y = 180y + z = w + x + yw + x + y = 180y + z = w + x + yw + x = zLearn more about Equation here -

Answer:
A
Step-by-step explanation:
We cannot take the square root of a negative number without using complex numbers. Because of this, both 5x and x+3 must be non-negative in order for the product to be defined.
5x ≥ 0 implies that x ≥ 0x + 3 ≥ 0 implies that x ≥ -3Both of these are satisfied if and only if x ≥ 0 (note that if x ≥ 0, then x is automatically greater than or equal to -3). Therefore, the correct answer is x ≥ 0.

At Dairy Freeze, 2 of the last 10 sundaes sold had nuts. Considering this data, how many of the next 20 sundaes sold would you expect to have nuts?
Answers
Answer: 4
Step-by-step explanation:
By finding the relative frequency, we will see that we can expect that 4 out of the next 20 sundaes will have nuts.
How many of the next 20 sundaes can we expect to have nuts?
First, we know that 2 out of the last 10 sundaes sold had nuts. So the relative frequency of sundaes with nuts is:
R = 2/10 = 0.2
(the quotient between the number of sundaes with nuts and the total number of sundaes)
Then, out of the next 20 sundaes, we can expect that the number of sundaes with nuts will be:
N = R*20 = 0.2*20 = 4
