Answer:
y = 3x +1
Step-by-step explanation:
The line intersects the y-axis at y=1, so the y-intercept is ...
b = 1
The line rises 3 grid squares for each 1 grid square to the right, so the slope is ...
m = rise/run = 3/1 = 3
Then the slope-intercept equation of the line is ...
y = mx +b
y = 3x +1

Answer:
Your answer is 2.042
Step-by-step explanation:
If you want it simplified you can change it to
2.0/2.04.
The decimal notation of two and forty-two thousandths is 2.042.
Given that, two and forty-two thousandths.
Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.
Here, 2+42/1000
= 2+0.042
= 2.042
Therefore, the decimal notation of two and forty-two thousandths is 2.042.

Answer:
It's an Irregular Quadrilateral
Step-by-step explanation:
It has 4 sides and the length of the sides of the Quadrilateral is not equal. This makes it irregular.
Answer:
Irregular Polygons
Step-by-step explanation:
Let's us first learn the definition of a polygon. A polygon is a closed shape figure that has a minimum of three sides and three vertices. The term ‘poly’ means ‘many’ and ‘gon’ means ‘angle’. Thus, polygons have many angles. The perimeter and area of polygon depend upon its types.
The classification of polygons is described based on the numbers of sides and vertices. For example, a polygon as four sides and four angles, then it is quadrilateral. The polygons up to 12 sides are the important ones. We are going to learn here polygon’s types based on the number of sides of the closed figure along with examples and diagrams.
Polygons are classified into various types based on the number of sides and measures of the angles. They are:
Regular PolygonsIrregular PolygonsConcave PolygonsConvex PolygonsTrigonsQuadrilateral PolygonsPentagon PolygonsHexagon PolygonsEquilateral PolygonsEquiangular PolygonsRegular PolygonIn a regular polygon, all the sides of the polygon are equal, and all the interior angles are the same. For example, a regular hexagon has six equal sides, and all its interior angles measure to 120 degrees.
Irregular PolygonA polygon with an irregular shape. It means the sides and angles of the polygon are not equal.
Convex PolygonIn a convex polygon, the measure of the interior angle is less than 180 degrees. It is exactly opposite to the concave polygon. The vertices of a convex polygon are always outwards
Concave PolygonIn a concave polygon, at least one angle measures more than 180 degrees. The vertices of a concave polygon are inwards as well as outwards.
TrigonsTrigons are polygons who have three sides. They are nothing but triangles. These trigons or triangles are further classified into different categories, such as:
Scalene Triangle: All sides are unequalIsosceles Triangle: Two sides are equalEquilateral Triangle: All the three sides are equal and all angles measures to 60 degrees.Quadrilateral PolygonQuadrilateral polygon is also called a four-sided polygon or a quadrangle. The different types of the quadrilateral polygon are square, rectangle, rhombus and parallelogram.
Pentagon PolygonThe five-sided polygon is called pentagon polygon. When all the five sides of the polygon are equal in length, then it is called regular pentagon otherwise irregular pentagon.
HexagonsAnother type of polygon is the hexagon which has 6 sides and 6 vertices. A regular hexagon will have equal 6 sides and all its interior and exterior angles also measure equals.
Equilateral PolygonsThe polygons whose all the sides are equal are called equilateral polygons, for example, an equilateral triangle, a square, etc.
Equiangular PolygonsThe polygons whose all the interior angles are equal such as a rectangle are called equiangular polygons.

What is the equation of the parabola ?
Answer:
D. y = 1/12x² + 2Step-by-step explanation:
As per graph we observe:
The y-intercept is 2The coefficient is positive as the graph opens upAccording to the observations, the equation is:
y = 1/12x² + 2Correct choice is D
b is y intercept,a is coefficient
Here a is 1/12 as every option contains this factor so don't calculate.
As parabola is opening upwards a is positive
and
y intercept is 2
So the equation is
y=1/12x²+2Choose the correct inequality symbol to make the inequality below true. Please help me.
Todd orders pictures from a photographer. Each picture cost $7.50. A one time shipping fee of $3.25 is added to the cost of the order. The total cost of Todd’s order before tax is $85.75. How many pictures did Todd order?
The equation for the number of pictures is, 7.50x + 3.25 = 85.75 and Todd ordered 11 pictures.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
From the given information, Let the number of pictures be 'x'.

The value of a in y³ - 5y² + 72y - 68 = 0 is -5
Quadratic equation
A quadratic equation is in the form:
ax² + bx + c = 0
where a, b, c are constants integers.
Given the roots of the equation as 1 and 2 - 8i, hence the third root is 2 + 8i. Complex roots are in conjugate pairs, hence:
y = 1 or y = 2 - 8i or y = 2 + 8i
(y - 1) = 0; y - 2 + 8i = 0 and y - 2 - 8i = 0
(y - 1)(y - 2 + 8i)(y - 2-8i) = 0
y³ - 5y² + 72y - 68 = 0
The value of a in y³ - 5y² + 72y - 68 = 0 is -5

How many inches is the diagonal distance.? WRITE THE ANSWER TO THE NEAREST INCH
Answer:
37 in (to the nearest inch)
Step-by-step explanation:
Assume the TV is rectangular ⇒ each corner is a right angle.
We need to find the length of the diagonal, so we can use Pythagoras' Theorem a² + b² = c² where a and b are the legs and c is the hypotenuse (diagonal) side of a right angled triangle.
In this diagram, a and b are the height and width, and the diagonal (c) is the hypotenuse.
Therefore, if a = 18 and b = 32 then:
18² + 32² = c²
324 + 1024 = c²
c² = 1348
c = √(1348)
c = 36.7151195...
c = 37 (rounding up to the nearest integer)
Therefore, the diagonal distance is 37 in (to the nearest inch)
On a 4-hour bike ride. Talal averaged 5.75 miles per hour. Write an equation and find the total distance.
Answer:
23 miles.
Step-by-step explanation:
Using the given, 4 and 5.75, we can create an equation.
To create a valid equation, we must multiply 4 and 5.75 to find the total distance.
4(5.75) = T
T = the total distance of the bike ride.
Solve:
4(5.75) = 23.
Your solution is 23 miles, the total distance of the bike ride.
