Answer:
(-1,-3) and (1,-1)
Sometimes you give the solutions as just the x.
x = -1 and x = 1
Step-by-step explanation:
The two curvy pieces are f(x) and the straight line is g(x). The solutions are where the two graphs intersect. There are two points where this happens: (-1,-3) and (1,-1).
Sometimes your teacher, the text or the course just wants you to give the answer as the x where it happens. The graphs intersects where x=-1 and x=1
How to find x and y? We didn’t study much about the rhombus at all
Answer:
answer can be any numbers but I will choose
x = 50° and y =130°
Step-by-step explanation:
We know all the inner degree of rhombus =360°
Then, x+y+x+y = 360°
or,2x + 2y = 360°
or, 2(x + y) = 360°
or, x + y = 360°/2
or,x + y = 180°
Let x = 50° then
50° + y = 180°
or, y = 180° - 50°
or, y = 130°

A boating company has the following notice at the gate:
"Children under the age of 13 are not allowed to operate a boat".
Part A- Write an inequality to show the age of children who are allowed to operate a boat.
Part B- Describe in words how you can show the solution to this inequality of a number line.
Answer:
Part A:
x > 13
Part B:
How to show this inequality on a number line is a closed circle on 13, going left of 13.
Step-by-step explanation:
Part A:
x represents the age of children who are allowed to operate the boat.
Our inequality is < because if you are of the age of 13 you are allowed to operate the boat,
the inequality x > 13 reads x (the age of children) is greater than or equal to 13
Part B:
How to describe inequalities on a number line;
Closed circle: less than or equal to - or - greater than or equal to ( < , > )
Open circle: less than - or - greater than ( < , > )
To the right of the number on the number line: greater than
To the left of the number on the number line: less than
Answer:
Part A
Let x = age of child (in years)
Given:
"Children under the age of 13 are not allowed to operate a boat"
Therefore, children should be 13 or older:
⇒ x ≥ 13
Part B
Place a closed circle at 13.
Shade to the right of the closed circle.
Explain a situation where the probability could be equally unlikely
Equally likely refers to two or more possible outcomes of a given situation that have the same probability or the same likelihood to occur. For example, if you throw a die, there are six possible outcomes. You could get 1, 2, 3, 4, 5, or 6. These outcomes are equally likely to occur.

Find the maximum height of the equation -16x^2+64x+86=0
Answer:
max = 150
Step-by-step explanation:
the maximum height is the value of the y- coordinate of the vertex.
given a quadratic equation in standard form : y = ax² + bx + c = 0 ( a ≠ 0 )
then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
- 16x² + 64x + 86 = 0 ← is in standard form
with a = - 16 and b = 64 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{64}{-32}[/tex] = 2
substitute x = 2 into the quadratic for corresponding y- coordinate
- 16(2)² + 64(2) + 86 = - 16(4) + 128 + 86 = - 64 + 128 + 86 = 150
vertex = (2, 150 )
then maximum height is 150 units

352,345,338,... Find the 43rd term
Step-by-step explanation:
it seems we are dealing with subtraction, as the differences between the 1st and second, and between the 2nd and 3rd numbers are equal : -7
so, we can assume that the sequence is created by always subtracting 7.
a1 = 352
a2 = a1 - 7 = 352 - 7 = 345
a3 = a2 - 7 = a1 - 7 - 7 = 352 - 7 - 7 = 338
an = an-1 - 7 = a1 - 7(n-1) = 352 - 7(n-1)
a43 = 352 - 7(43-1) = 352 - 7×42 = 352 - 294 = 58
Determine and state an equation of the line perpendicular to the lines 5x-4y=10 and passing through the point (5,12). in point-slope form.
Please help I will mark branilest!!! and give 100 points
The equation of the line in point-slope form is: y - 12 = -4/5(x - 5).
What is the Equation of a Line in Point-slope Form?It is given as, y - b = m(x - a), where (a, b) is a point on the line and m is the slope of the line.
Rewrite 5x-4y=10 in slope-intercept form:
-4y= - 5x + 10
y= -5x/-4 + (10/-4)
y = 5/4x - 5/2
The slope is 5/4
The line that is perpendicular to 5x-4y=10 will have a slope which is the negative reciprocal of 5/4, which is -4/5.
Substitute (5, 12) and -4/5 into y - b = m(x - a):
y - 12 = -4/5(x - 5) [point-slope form]

The total surface area of the three figures are 702 square feet.
How to estimate the amount of metal needed to produce a given amount of figures
According to this problem, we are required to determine the amount of metal needed to build three pieces with the dimensions presented in the figure.
In this case, we need to estimate the total surface area ([tex]A_{T}[/tex]), in square feet, required for the production of the three pieces, that is, the product of the number of pieces (n), no unit, and the surface area of each piece (A).
Now we proceed to calculate the total surface area:
