10) The second pair of coordinate on the line parallel to q and passes through the point (1, 0) is (-5, 0).
11) The second pair of coordinate on the line perpendicular to q and passes through the point (3, 5) is (2, 0).
What is a slope?When the ratio is expressed as a quotient ("rise over run"), the same number is provided for every two distinct locations on the same line. There is a negative "rise" on a descending line.
Given,
Line q passes through (3, 5), (-2, 4)
(y-y₁)=m(x-x₁)
(y-5)=((4-5)/(-2-3))(x-3)
(y-5)=(-1/-5)(x-3)
-5y+25=-x+3
x-5y+22=0
10) Given point is (0,1)
Slopes are equal for parallel lines.
So, (y-1)/(x-0)=(-1/-5)
-5y+5= -x
x-5y+5=0Let y=0 then,
x= -5
Therefore, the second pair of coordinate on the line parallel to q and passes through the point (1, 0) is (-5, 0).
11) The equation of a line perpendicular to q is,
(y-y₁)=(-1/m)(x-x₁)
(y-5)=5(x-3)
y-5=5x-15
5x-y-10=0
Let y=0 then,
5x-10=0
x=2
Therefore, the second pair of coordinate on the line perpendicular to q and passes through the point (3, 5) is (2, 0).

D
∠W≅∠E
Answers
Answer:
(A) ∠Y ≅ ∠C.
Step-by-step explanation:
To prove that two triangles are congruent by ASA (Angle-Side-Angle), you need to show that two angles in one triangle are congruent to two corresponding angles in the other triangle, and that the side between the two angles is congruent to the corresponding side in the other triangle.
Given that ∠X ≅ ∠D and ∠DE ≅ ∠XW, the third congruence needed to prove that ΔXWY ≅ ΔDEC by ASA is:
(A) ∠Y ≅ ∠C
This is because ∠Y and ∠C are the corresponding angles in the two triangles that have not been shown to be congruent.
So the answer is (A) ∠Y ≅ ∠C.

2. Dimensions of shape 2: Length is 8 ft, and width is 6 ft
Step 2: Multiply the length by the height of each shape
Area = lw
3. Area of shape 1: 10 ft ∙ 4 ft = 40 ft²

Write an equation for the line.
Answers
Answer:
y = 2x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 0) ← 2 points on the line
m = [tex]\frac{0-(-2)}{1-0}[/tex] = [tex]\frac{0+2}{1}[/tex] = [tex]\frac{2}{1}[/tex] = 2
the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2
y = 2x - 2 ← equation of line
Answer:
y = 2x - 2
Step-by-step explanation:
The equation y = mx + b is a standard form of a linear equation in one variable. It represents a straight line on a graph
In this equation, y is the dependent variable, which is the variable that is being measured or predicted. The independent variable is x, which is the input or cause in the relationship.
The coefficient m is the slope of the line, which tells you the rate of change between the two variables. It represents how much the value of y changes for each unit change in the value of x. A positive slope means that the line goes up as you move from left to right, while a negative slope means that the line goes down.
- Our slope is positive
- slope (m) = rise / run = 2/1 = 2
The constant b is the y-intercept, which is the point where the line crosses the y-axis. It represents the value of y when x is equal to 0.
- Our y-intercept is -2
m is 2 and b is -2, the equation y = 2x - 2 represents a line with a slope of 2 and a y-intercept of -2. This means that for every 1 unit increase in the value of x, the value of y increases by 2 units, and the line crosses the y-axis at the point (0, -2).

The attached graph is defined by f(x) = x² + 5|x| + 6.
What is the graph function?
The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function is a special case of the graph of an equation.
We have,
y = x² + 5|x| + 6
we know,
|x|² = x² use this ,
y = |x|² + 5|x| + 6
Steps for drawing y = |x|² + 5|x| + 6
step1 :- first draw y = x² + 5x + 6, this graph is quadratic equation .
step2:- Leave the part of y=x² + 5x + 6 right side to the y-axis and also take its image with respect to the y-axis as a plane mirror.
step3 :- now remove the part of y = x² + 5x + 6 to left side from y - axis .
now your graph is ready
you can see in the figure attached.
Hence, the attached graph is defined by f(x) = x² + 5|x| + 6.

Use synthetic division to solve (×3 + 1) = (X - 1). What is the quotient?
Answers
The required quotient is x² + x + 1 + (2/ x -1) which is determined by the synthetic division.
What is the Quotient?A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient.
Use the divisor and find x :
x - 1 = 0 add 1
x= 1
Now we'll divide with the number one:
Take the coefficients from the terms in front of them.
Make careful to include 0's for x² and x since all terms must be included.
set it up with a 1 in a box:
1| 1 0 0 1 bring the first number down
____________
1 multiply the boxed number by the first number and add it to the second number
1| 1 0 0 1
____+1_____ repeat with the rest of the terms
1 1
1| 1 0 0 1
___+1_+1_+1
1 1 1 2
When you're finished, use the new numbers to build an equation that begins with a term that has one fewer degree than the previous equation.
Because there is a remnant, divide it by the original divisor.
final answer:
x² + x + 1 + (2/ x -1)
Thus, the required quotient is x² + x + 1 + (2/ x -1) which is determined by the synthetic division.

B i the midpoint of AC. D i the midpoint of CE. DE=5 and AE=18. What i the length of BD?
Answers
The length of BD is 9 units when considering the idea of a line segment's midpoint.
What is midpoint of line segment ?A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. The midpoint is the point on the middle of the line that is equally distant from the two points if a line is drawn connecting the two points. The midpoint is the point B that lies halfway between any two points, let's say A and C. As a result, measuring the length of the line segment and dividing it by two will yield the midway.
According to the given information :
AE = 18, DE = 5
However, D is the middle of CE
CE = 2 × 5 = 10
The line CE will become 10
But AE is the total length of the line segment and it is equal to 18
AE = AC + CE
AC = AE - CE
AC = 8

A car drives down a road in such a way that its velocity (in m/s) at time t (seconds) is v(t)=2t1/2+1. Find the car's average velocity (in m/s) between t=4 and t=8
Answers
Average velocity of the car as calculated from the given data is 6m/s.
The average velocity is calculated by dividing the total distance travelled by the whole time that has passed. Given the velocity as a function of time, you may integrate the velocity function from t = 4 to t = 8 to determine the total distance travelled.
The opposite of taking a derivative is to integrate; in other words, the function I get when I take a derivative is 2t1/2 + 1. Assuming you are aware of how to do that If not, you can input the aforementioned integral into your TI-84 to obtain the result.
The integral turns out to be
(4/3)t^3/2 + 4t so x(t)
= (4/3)t3/2 + 4t and x(8) - x(4)
= (4/3)(8)3/2 + 4(8) - [(4/3)(4)3/2 + 4(4)]
= 24 meters
The distance travelled in total was 24 meter and it took 4 seconds (8-4) to do it, so the average velocity is 24 /4 = 6 m/s.
