Three more than twice a number is greater than negative .fifteen. Solve the inequality for the unknown number.
Answer: n > -9
Step-by-step explanation:
3+2n > -15
2n> -18
n > -9
Write an inequality to represent the model and solve for the unknown number
let
the unknown number = x
twice a number = 2 × x
= 2x
Three more than twice a number = 2x + 3
Three more than twice a number is greater than negative fifteen:
2x + 3 > -15
2x > -15 - 3
2x > - 18
Divide both sides by 2
x > -18/2
x > -9
Therefore, the unknown number x, is greater than -9

The coordinates for point M is (12, 6)
what is section formula?Section formula is used to find the coordinates of a point that splits a line segment internally or externally into a ratio of m:n.
(x, y) = ( mx2 + nx1/ m+n, my2 + ny1/ m+n)
Given:
Coordinates of A(0, 15) and B (20, 0)
ratio is 3:2
Now,
x1=0, x2= 20, y1= 15, y2=0
let the coordinates of M is (c, d)
Using section formula
c=2*0+3*20/5
c=12
and d= 15*2+ 2*0/5
d= 6
Hence, the coordinates of M are (12, 6).

Statements Reasons 1. circle O has diameter LN and inscribed angle LMN 1. given 2. is a semicircle 2. diameter divides into 2 semicircles 3. circle O measures 360o 3. measure of a circle is 360o 4. m = 180o 4. definition of semicircle 5. m∠LMN = 90o 5. ? 6. ∠LMN is a right angle 6. definition of right angle HL theorem inscribed angle theorem diagonals of a rhombus are perpendicular. formed by a tangent and a chord is half the measure of the intercepted arc.
Answer:
Inscribed angle theorem
Step-by-step explanation:
This theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
In this case, the angle is ∠LMN and the arc is arc LN. Arc LN measures 180°, because segment LN is the diameter of the circle. Then, by the theorem:
∠LMN = (1/2)*arc LN = (1/2)*180° = 90°
Answer:
B. Inscribed Angle theorem

What is the area of the squares with sides (2x-3)feet?
Answer:
4x^2 -12x +9 ft^2
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
A = (2x-3) ^2
A = (2x-3) (2x-3)
FOIL
first 2x*2x =4x^2
outer 2x (-3) = -6x
inner -3*2x = -6x
last -3*-3 = 9
Add them together
4x^2 -6x-6x +9
Combine like terms
4x^2 -12x +9
The area is 4x^2 -12x +9 ft^2

Matthew has $1,500 in his savings account. Currently, he pays $20 each month for an
app that he has subscribed to and $30 each month at his favorite Italian restaurant. If
he does not spend money on anything else or make any other deposits into his savings
account, for how many months can he continue to make these purchases without going
into debt?
Answer: 30 months
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
Matthew's saving account money (1500) must be equal to the product of the amount he pays per month for the app subscription (20) and the number of months (x); plus the product of the amount he pays per month for the Italian restaurant subscription (30) and the number of months (x).
1500= 20x+30x
Solving for x:
1500=50x
1500/50 =x
30 months =x

Write an equation for the function that includes the points (3,12) and (4, 24)
10 points
fx=6/3 * 2^x
fx= 3/2 * 2^x
fx = 2x
Answer:
Equation for the function is:
f(x) = (3/2) · 2ˣ
Step-by-step explanation:
We have been provided with 2 points
Point 1 : (3, 12)
Point 2 : (4, 24)
Testing all three equations:
1) f(x) = 6/3 · 2ˣ
Substitute x of Point 1 in the equation
f(x) = (6/3) · 2³
f(x) = 16
y = 16 ≠ 12
NOT TRUE
Substitute x of Point 2 in the equation:
f(x) = (6/3) · 2⁴
f(x) = 32 ≠ 24
NOT TRUE
2) f(x) = 3/2· 2ˣ
Substitute x of Point 1 in the equation
f(x) = (3/2) · 2³
f(x) = 12
y = 12
TRUE
Substitute x of Point 2 in the equation:
f(x) = (3/2)· 2⁴
f(x) = 24
TRUE
3) f(x) = 2x
Substitute x of Point 1 in the equation
f(x) = 2(3)
f(x) = 6
y = 6 ≠ 12
NOT TRUE
Substitute x of Point 2 in the equation:
f(x) = 2(4)
f(x) = 8 ≠ 24
NOT TRUE
Which expression is the factorization of x2 + 10x + 212
O (x+3)(x + 7)
O (x + 4)(x+6)
O (X+6)x+15)
O(x + 7)(x+14)
Answer:
The answer is option 1.
Step-by-step explanation:
Firstly, you have to elaborate the expression :
[tex] {x}^{2} + 10x + 21[/tex]
[tex] = {x}^{2} + 3x + 7x + 21[/tex]
Next you have to take out the common factors and factorize it :
[tex] {x}^{2} + 3x + 7x + 21[/tex]
[tex] = x(x + 3) + 7(x + 3)[/tex]
[tex] = (x + 7)(x + 3)[/tex]
The right answer is (X+3)(X+7)

what is the coefficient of 7c+8?
1) 1
2)8
3)7
4)c
The coefficient of 7c + 8 is the coefficient of the term with the variable c, which is 7.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
Unknown variables, numbers, and arithmetic operators make up an algebraic expression. It contains no equality or inequality symbols.
The given expression is 7c + 8.
A coefficient is a numerical factor that appears before a variable in a term. In this expression, 7c is a term, where 7 is the coefficient of c. Similarly, 8 is also a term, where the coefficient is 8.
Since integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer.
Therefore, the coefficient of 7c + 8 is the coefficient of the term with the variable c, which is 7.
So, the answer is option 3, which is 7.

Find the volume of this cylinder. Give your answer to one decimal place.
Answer:
1329.8 cm³
Step-by-step explanation:
Volume of a Cylinder is: [tex]V=\pi r^2h[/tex]
We are given the height of 14 cm, and the diameter of 11 cm.
The radius is half the diameter.
[tex]11/2=5.5[/tex]
The radius is 5.5.
I use 3.14 for pi:
[tex]V=3.14*5.5^2*14\\\rightarrow 5.5^2=30.25\\V=3.14*30.25*14\\\boxed{V=1329.79}[/tex]
1329.79 ≈ 1329.8
The volume of the cylinder should be 1329.8 cm³.

[tex]S_{15}=\frac{15}{2}(a_{1}+l)\\\\240=\frac{15}{2}(a_{1}+33.5)\\\\240*2=15*(a_{1}+33.5)\\\\480=15*(a_{1}+33.5)\\\\\frac{480}{15}=a_{1}+33.5\\\\32=a_{1}+33.5\\\\32-33.5=a_{1}\\-1.5=a_{1}[/tex]
