Answer:
(x-3)(x+5) = 0
x-3 = 0 and x+5=0
x=3 and x=-5 when y=0
y = x^2+2x-15
complete the square
= x^2+2x + 1 -15 - 1

y intercept = -15 or the point (0,-15)
x intercepts = 3 and -5 = the two zeroes or roots, or the points (3,0) and (-5,0)
vertex or minimum point of the upward opening parabola is (-1,-16)
note the 2 zeroes are both 4 units horizontally from the vertex x value, 3 to -1 is 4, and -1 to -5 is 4.

the box that shoes come in are often used in other capacities once the shopper has bought theshoes sometimes the boxes are used to hold other items so it is helpful to know the volume of the box if the area of the base of the box is 112 square inches and the hight is 3.5 inches. What is the vloume of the box?
The box with area of the base of the box is 112 square inches and the height is 3.5 inches has volume of 392 in³
A cuboid is a three dimensional shape polyhedral with six quadrilateral faces. The volume of a cuboid is:
Volume of cuboid = length * width * height
A box is a three dimensional shape in the form of a cuboid. The volume of a box is:
Volume of box = length * width * height
Volume of box = area of base * height
The area of the base of the box is 112 square inches and the height is 3.5 inches, hence:
Volume of box = 112 in² * 3.5 in
Volume of box = 392 in³
The box has volume of 392 in³

Mia is solving the equation x2 – 12x = 1. Which value must be added to both sides of the equation to make the left side a perfect-square trinomial?
9
-9
36
8
The value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.
To make the equation x2 – 12x = 1 look similar to the completing the square kind of expression where the left hand side of the equation becomes a perfect square, we must do the following;
First, the completing the square method usually takes the form; x² + bx = (x + b/2)² + cIn this scenario, the term (x² - 12x) can be rewritten as; (x - 6)² - 36.
This so because the expansion of (x - 6)² becomes;
x² - 12x + 36.Therefore, there's a need to subtract 36 from both sides of the equation so that the equation x2 – 12x = 1 is retained.
Therefore, the value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.

The answer is C (-3 , -3) and (-3 , 3)
Step-by-step explanation:
the other answer was already right.
yes, C (-3, -3) and (-3, 3)
but why ?
the slope is the y/x ratio of the x and y coordinate differences when going from one point to the other.
so, x changes 0 units. y changes 6 units (from -3 to 3).
so, the slope is 6/0 = infinite or simply undefined.
this is a vertical line at x = -3.

Answer:
y = 6
Step-by-step explanation:
[tex]3(y - 5) + 2 = 5 \\ 3y - 15 + 2 = 5 \\ 3y - 13 = 5 \\ 3y = 5 + 13 \\ 3y = 18 \\ \\ y = \frac{18}{3} \\ \\ y = 6[/tex]
I hope I helped you^_^
The solution of the equation 3(y - 5) + 2 = 5 gives the result y = 6.
Thus, option (d) is correct.
An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=).
Let's solve the equation step by step:
3(y - 5) + 2 = 5
First, distribute the 3 on the left side:
3y - 15 + 2 = 5
Combine the constants on the left side:
3y - 13 = 5
Now, isolate the variable y by adding 13 to both sides:
3y = 18
Finally, divide both sides by 3 to solve for \(y\):
y = 18/3
y = 6
So, the solution to the equation is y = 6.
Thus, option (d) is correct.

= ( 5 . a^2 . b^3 ) ( 4 . a . b^5 )
= ( 5 . 4 ) ( a^2 . a ) ( b^3 . b^5 )
= 20 ( a^2 . a^1 ) ( b^3 . b^5 )

solve for r to find the missing term in geometric sequence
—
hi can someone please answer my question. thank you ❤️
Step-by-step explanation:
given :
120, 60, 30, _, _, _
find r!
solution :
r = 60/120 = ½.
=> 120,60,30, 15, 15/2 , 15/4 , ...
Step-by-step explanation:
Calcute the ratio :
r = Un/Un-1
r = 60/120
r = ½
Calculate 4th term :
Un = ar^n-1
U4 = 120 × ½^4-1
U4 = 120 × ½³
U4 = 120 × 0.125
U4 = 15
Calculate 5th term :
Un = ar^n-1
U5 = 120 × ½^5-1
U5 = 120 × ½⁴
U5 = 120 × 0.0625
U5 = 7.5
Calculate 6th term :
Un = ar^n-1
U6 = 120 × ½^6-1
U6 = 120 × ½⁵
U6 = 120 × 0.03125
U6 = 3.75
Sam walked x miles at 4mph.
Then he walked 2x miles at 3mph.
A) find average speed for the whole journey.
The second part of journey took 25mins longer than the first part.
B) Find the value of x.
Answer:
Sam average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
Step-by-step explanation:
Formula: Speed = [tex]\frac{Distance}{Time}[/tex]
i.e. Time = [tex]\frac{Distance}{Speed}[/tex]
If Sam walked x miles at 4 mph, then time taken by him = [tex]\frac{x}{4}[/tex] hours
If he then walked 2x miles at 3 mph, then time for this period = [tex]\frac{2x}{3}[/tex]hours
Average speed = [tex]\frac{Total Distance}{Total Time}[/tex]
=[tex]\frac{x+2x}{\frac{x}{4} \frac{2x}{3} }[/tex]
=[tex]\frac{3x}{\frac{x1}{4} \frac{2}{3} }[/tex]

x + y = 36
x = (4/5)y
we use the second equation as substitute in the first

The waves will cover a circular area of 7542.96 miles.
What is the area of the circle?The circle is defined as the locus of the point traces around a fixed point called the center and is equidistant from the outer trace. The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that a radio station sends out radio waves in all directions from a tower at the center of the circle of broadcast range. The circle has a diameter of 98 miles.
The area of a circle is calculated by the formula below:-
Area = ( π / 4 ) d²
Area = ( π / 4 ) ( 98 )²
Area = 7542.96 square miles
Therefore, the waves will cover a circular area of 7542.96 miles.
