Answer:
x=7
Step-by-step explanation:
In this question, since the horizontal lines are parallel lines, these two angles are congruent to each other.
So we have: 105=16x-7
Equation: 105=16x-7
Add 7 to both sides: 112=16x
Divide by 16 on both sides: x=7

Use the graph of the polynomial
function to find the factored form of
its related polynomial. Assume it
has no constant factor
Answer:
The factored form of the polynomial is [tex]y = (x-2)\cdot (x+1)[/tex].
Step-by-step explanation:
According to the graph, we have a second order polynomial with a vertical axis of symmetry. The standard form of the polynomial is:
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.
We can obtain the solution of the polynomial by knowing three distinct points. From graph we know that the curve pass through the following three points: [tex](x_{1},y_{1}) = (-1, 0)[/tex], [tex](x_{2},y_{2}) = (0, -2)[/tex], [tex](x_{3},y_{3}) = (2,0)[/tex]. Three linear equations are constructed:
[tex]a^{2}-b+c = 0[/tex] (2)
[tex]c = -2[/tex] (3)
[tex]4\cdot a + 2\cdot b + c = 0[/tex] (4)
The solution of this system is [tex]a = 1[/tex], [tex]b = -1[/tex] and [tex]c = -2[/tex]. Then, the polynomial in standard form is [tex]y = x^{2}-x-2[/tex]. By factorization, we find that factored form is:
[tex]y = (x-2)\cdot (x+1)[/tex] (5)
Find (4.2) x (1.6) by drawing an area diagram or using another method. Show your reasoning. Pleae answer this I really need help. PLZ
Answer:
the answer is 6.72
Step-by-step explanation:
Instead of a diagram you can do 4.2 times 1.6 and after you finishes doing that You put the decimal 2 times and you should get 6.72
The answer is 6.72
What is area diagram method?The length and width of a rectangle are defined by the factors being multiplied in an area model, which is a rectangular diagram used in mathematics to solve multiplication problems. Therefore, the area of the rectangle is the product. Subsequently, it is known as the "Region model for augmentation".
Given (4.2) x (1.6)
by area drawing method make an rectangle of 4.2 and 1.6 units and make perpendicular lines at distance of 4 units and 1 units on length and breadth, the rest distance will be 0.6 and 0.2 units, now we have four different rectangles as shown in image now find area of each rectangle and add all the areas.
area of rectangle 1 = 4 x 1 = 4
area of rectangle 2 = 1 x 0.2 = 0.2
area of rectangle 3 = 4 x 0.6 = 2.4
area of rectangle 4 = 0.2 x 0.6 = 0.12
total area = 4 + 0.2 + 2.4 + 0.12
total area = 6.72
Hence (4.2) x (1.6) = 6.72

What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related. They can answer geometrical problems because it gives them geometrical aspects of algebra. In this area of geometry, a pair of ordered numbers is used to describe the location of points on a plane.
As per the given data:
Coordinates of point V = (3, -7)
Rotation to be given = 180° (clockwise)
For drawing the image of point V (3, -7):
Step 1: Draw a line passing through the origin and V (3, -7) extending through 2nd and 4th quadrant.
Step 2: Change sign of x and y coordinates as rotation is of 180° and mark the point in the 2nd quadrant.
Image of the point V is V' = (-3, 7) as shown in the graph below.
Hence, the image of the point V is V' = (-3, 7).

Mario is constructing a wall around a rectangular area which will cover a maximum of 60 square feet. The length of the wall will be 10
feet.
Which inequality represents all the possible widths in feet, w, that Mario can use to construct the rectangular
wall?

Answer:
[tex]W \le 6[/tex]
Step-by-step explanation:
Given
[tex]Area = 60ft^2\ (max)[/tex]
[tex]Length = 10ft[/tex]
Required
Represent the width as an inequality
First, we represent the area as an inequality.
[tex]Area = 60ft^2\ (max)[/tex]
max as used above means less than or equal to.
So, we have:
[tex]Area \le 60[/tex]
The area of a rectangle is:
[tex]Area = L * W[/tex]
So, we have:
[tex]L * W \le 60[/tex]
Substitute 10 for L
[tex]10 * W \le 60[/tex]
Divide both sides by 10
[tex]\frac{10 * W}{10} \le \frac{60}{10}[/tex]
[tex]W \le \frac{60}{10}[/tex]
[tex]W \le 6[/tex]

Which is the graph of y= -x-3?
Answer:
Graph a
Step-by-step explanation:
Answer:
the answer is A
Step-by-step explanation:
to start, I would use the slope intercept, in this case -3 which lets you know the slope meets the y axis at (0,-3) since you have that point, you count with the slope.
now slope is rise over run, therefore, it would be y over x and since the y in this case is 3, you'd go up three from your point. since x is 4, you'd go right four units from where you are. since A is the only graph that follows that, A would be correct.

What is the value of n?
Answer:
B. 85 degrees
Step-by-step explanation:
To find the top angle inside the tringle, do 180-133 = 47. To find the angle on the left, do 180 - 142 = 38. Do 180 - 47 + 38 = 95 to find the final angle. Then do 180-95 = 85 to find the angle wanted. This is all about using lines, because the angles on both sides of the line must add to 180 if one of the lines they lie on is the same. Hope this makes sense.

What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the slope of the line is 2 and the point through which it is passing is (-1,4).
The equation of the line will be calculated as,
y = mx + c
y = 2x + c
4 = -2 + c
c = 6
The equation will be written as,
y =2x + 6
The graph of the line is attached with the answer below.
