Answer:
x^2 + 16x - 15 = 0.
Step-by-step explanation:
x^2 + 16x – 11 = 4 Subtract 4 from both sides:
x^2 + 16x - 15 = 0 is one equation with the same roots.
Also any equation which is a multiple of the above will have the same roots. For example if we multiply by 3:
3x^2 + 48x - 45 = 0.

find x using
dialations
Answer:
x = 14.4
Step-by-step explanation:
Using dilations, the following equation can be written to show the relationship between the two similar triangles:
x/4 = (6.5 + 2.5)/2.5
x/4 = 9/2.5
Cross multiply
x*2.5 = 9*4
2.5x = 36
2.5x/2.5 = 36/2.5
x = 14.4

Find the volume of the sphere. Round your answer to the nearest tenth.
Answer:
See below.
Step-by-step explanation:
The formula for the volume of a sphere
= 4/3 π r^3 where r = the radius.
So for number 1:
V = 4/3 π (5)^3
= 523 .60 mm^3 to nearest hundredth.
The others are solved in exactly the same way except where the diameter is given as in number 4 and 5 you get the radius r by dividing the diameter by 2. So in number 4, r = 30/2 = 15.
Write a quadratic function in standard form whose graph satisfies the given conditions.
passes through
0, 0 , 2, 4 , and 4, 0
Answer:
y = -x² + 4xStep-by-step explanation:
The standard form:
y = ax² + bx + cPairs given:
(0, 0), (2, 4), (4, 0)Substitute values of x and y and work out the values of a, b and c.
1. Point (0, 0)
0 = a(0)² + b(0) + c ⇒ c = 02. Point (2, 4)
4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a3. Point (4, 0)
0 = a(4)² + b(4) ⇒ 16a + 4b = 0Substitute b and solve for a:
16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1Find b:
b = 2 - 2(-1) = 2 + 2 = 4The function is:
y = -x² + 4x
A clothing manufacturer offers 2 different styles of jeans, relaxed fit and regular fit, in 5 different colours. How many combinations of a style and a colour are possible?
Answer:
10 combinations
Step-by-step explanation:
We can solve the above question using the Fundamental Counting Principle.
This states that:
If an event has x possible outcomes and a other event has y possible outcomes, then there are x and y total possible outcomes for the two events together.
We are told in the above question that:
Styles of jeans = 2
Number of colors = 5
Hence,the number of combinations of a style and a colour that are possible is calculated as:
5 × 2 = 10 combinations

x = (- (-7) ±√121 )/12x = (7 ± 11)/12x = 1.5, x = -1/3Write the equation based on the picture and calculate the mass of the unknown package.
Answer:
Step-by-step explanation:
5x + 2 = 4 x + 7
x = 5
Answer:
5x + 4 = 4x + 7
x = 3
Step-by-step explanation:
Let's call the mass of the unknown package "x". The equation is:
2+2 + x+x+x+x+x = x+x+x+x + 2+5
5x + 4 = 4x + 7
Now let's solve for x
5x + 4 = 4x + 7
x + 4 = 7
x = 3
