Answer: x = -1, 15
Step-by-step explanation:
15 = x²- 14x
⇒ x²- 14x-15 = 0
⇒ x²- 15x+x-15 = 0
⇒ x (x-15) + (x-15) = 0
⇒ (x-15) (x+1) = 0
Now,
x= -1, 15

What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
We have to given the function is,
3 (x - 2) - 4 (x + 1) = -22
Now, We can solve the expression as,
3 (x - 2) - 4 (x + 1) = -22
Use Multiplicative property;
3x - 6 - 4x - 4 = -22
Use addition and subtraction property,
- x - 10 = - 22
Use addition property and Add 22 both sides;
- x - 10 + 22 = - 22 + 22
- x + 12 = 0
Use subtraction property, Subtract 12 both sides;
- x + 12 - 12 = 0 - 12
- x = - 12
Multiply by -1 in both sides,
x = 12
Therefore, The solution of the equation 3 (x - 2) - 4 (x + 1) = -22 is,
⇒ x = 12

Step-by-step explanation:
t = number of t-shirts
n = number of notebooks
n + t = 70
5n + 11t = 500
n = 70 - t
5(70 - t) + 11t = 500
350 - 5t + 11t = 500

Find the coordinates of the missing endpoint if B is the midpoint of AC.
C(5/3,-6), B(8/3, 4)
The coordinates of the missing endpoint are (11 / 3, 14).
How to determine the location of the missing endpoint of a line segment
Herein we find the coordinates of a endpoint and a midpoint of a line segment and the location of missing endpoint can be found by using the midpoint formula, whose definition is shown:
B(x, y) = 0.5 · A(x, y) + 0.5 · C(x, y) (1)
If we know that B(x, y) = (8 / 3, 4) and C(x, y) = (5 / 3, - 6), then the location of the missing endpoint is:
(8 / 3, 4) = 0.5 · A(x, y) + 0.5 · (5 / 3, - 6)
(16 / 3, 8) = A(x, y) + (5 / 3, - 6)
A(x, y) = (16 / 3, 8) - (5 / 3, - 6)
A(x, y) = (11 / 3, 14)

11. Twenty-four students in Jamal's class are wearing tennis shoes. There are
thirty students in his class. Jamal says that 70% of his class is wearing
tennis shoes. Is Jamal correct? Explain your reasoning.
Answer: Incorrect.
Step-by-step explanation: 24 out of 30 is 80.00%.
Step 1: We make the assumption that 30 is 100 % since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100 % = 30.
Step 4: In the same vein, x % = 24 .
Step 5: This gives us a pair of simple equations:
100 % = 30(1).
x % = 24(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100 % / x % = 30/24
Step 7: Taking the inverse (or reciprocal) of both sides yields
x/100 = 24/30
x = 80 %

1303045464 more tickets were sold last year than this year.
According to the given question.
Number of lottery tickets were sold last year = 5,526,572,333
And, the total number of tickets sold this year = 4,223,526,869
To find the how many more tickets were sold last year than this year, we will subtract the number of of tickets sold this year from the number of lottery tickets were sold last year.
Therefore, the numebr of more tickets were sold last year
= 5,526,572,333 - 4,223,526,869
= 1303045464
Hence, 1303045464 more tickets were sold last year than this year.

TranslationDilationReflectionRotationWhat is a rotation?A rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
From the graph (see attachment), we have the following data:
Points at J = (-6, -7)Points at K = (-6, -2)Points at L = (-3, -7)In Geometry, rotating a point 180° about the origin in a clockwise or counterclockwise (anticlockwise) direction would produce a point that has the coordinates (-x, -y).
By applying a rotation of 180° clockwise to triangle JKL, the location of J’ is given by:
Points at J = (-6, -7) → Points at J' = (-(-6), -(-7))

Step-by-step explanation:
Given graphed inequalities and a list of points, you want the point that is a "solution."
AssumptionsWe assume the graphed inequalities are part of a system of two inequalities and that a "solution" is one that must satisfy both of them. Any solution point will be in the doubly-shaded area, or on the solid blue boundary next to that area.
SolutionEach of the given points is 6 units from the origin on one of the coordinate axes. The only such point that lies in the doubly-shaded area is (-6, 0) on the negative x-axis.
The point (-6, 0) is a solution.
__
Additional comment
We know the kinds of inequalities that can give rise to a graph like this, but we don't know the question for which one of these points would be a solution. That is why assumptions are necessary.
The point (0, 6), for example, could be a solution to the question, "what set of values satisfies x-y ≤ 1, but not x+y < 3?"
