What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
Given the equation y=-2x+1
and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect.
Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel.
To have this result, we must have that they have the same slope but different y intercept.
That is take m = -2 and b any value different to +1. For example, the b = 6.
So, y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.

8 Rotate the point (-3,-4) around the origin 180 degrees. State the image of the point.
A (-4,-3)
B (-4,3)
C (4, -3)
D (3, 4)
Answers
Answer: D (3,4) trust and believe
brainlyst pls I think I spelt is wrong
Step-by-step explanation:
When a line or shape or point is rotated, it must be rotated around a point.
The image of the point is D. (3,4)
The point is given as:
[tex]\mathbf{(x,y) = (-3,-4)}[/tex]
A 180-degree rotation across the origin is represented as:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
Substitute values for the coordinates of the point (x,y)
[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]
Simplify
[tex]\mathbf{(-3,-4) \to (3,4)}[/tex]
Hence, the image of the point is D. (3,4)

Answers
Answer:
37.6 in
48.2 yd
Step-by-step explanation:
The are of a circle is given as :
Area = pi(d²) /4
Area = 1110.4in²
1110.4 = 3. 14 * d² / 4
1110.4 * 4 = 3.14 * d²
4441.6 = 3.14d²
d² = 4441.6 /3.14
d² = 1413.8051
d = 37.600
d = 37.6
8.)
Area, A = 1824.7yd²
1824.7 = 3. 14 * d² / 4
1824.7 * 4 = 3.14d²
7298.8 = 3.14d²
d² = 7298.8 / 3.14
d² = 2323.2801
d = sqrt(2323.2801)
d = 48.200
Hence, diameter = 48.2 yd

Need help with this question; What is the measure of one leg of a right angle given that the hypotenuse measure 14cm and the other leg measure 8cm? Please help with explanation. I'll mark you as brainiest.
Answers
Answer:
11.5 cm
Step-by-step explanation:
The dimensions of a right angled triangle can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
a² + 8² = 14²
a² + 64 = 196
a² = 196 - 64
a² = 132
find the square root of 132
a = 11.5 cm
