Give your answer in the form y=mx+c
Answers
Answer:
y = -5x - 5
Step-by-step explanation:
Given the standard form of an equation as y=mx+c
m is the slope
c is the intercept
Using the coordinate points
(1, 0) and (0,-5)
m = -5-0/0+1
m = -5/1
m = -5
Get the intercept
Intercept is the point where thee line cuts the y axis. intercept is -5
Get the equation:
Recall that y = mx+c
y = -5x + -5
y = -5x - 5
This gives the required equation

The proper angle for a ladder is about 75' from the ground. Suppose you have a 21 foot ladder. How high
can it reach?
Answers
The ladder gets propped against the house, making a 75 degree angle with the ground. We can use the fact that cos(75°)=base distance/length of ladder to figure out the length of the base. Multiplying both sides by length of ladder we get, length of ladder×cos(75°)=base distance.Nov 6, 2019
A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t, where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?
t = 3; It takes the ball 3 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 3; It takes the ball 3 seconds to reach the maximum height and 6 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
Answers
Answer:
The function is a parabola of the form . The the formula for the axis of symmetry of a parabola is. So it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

Answers
Answer:
(2,1)
Step-by-step explanation:
The coordinate point between two points divided between ratio a and b is expressed as;
(X, Y) = [(ax1+bx2/a+b,ay1+by2/a+b]
Given the coordinate points (-7,-5) and (5,3) divided within the ratio 1:3
X = ax1+bx2/a+b
X = 1(-7)+3(5)/1+3
X = -7+15/4
X = 8/4
X = 3
Similarly
Y = ay1+by2/a+b
Y = 1(-5)+3(3)/1+3
Y = -5+9/4
Y = 4/4
Y = 1
Hence the required coordinate point is (2,1)

Answer:
this problem has this form, (x,y) (x-7)(y+5) and tells you that the X and Y coordinates are translated to X-7 and Y+5.
Step-by-step explanation:
The translated point A' of the triangle is given by A' ( -3 , 13 )
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the triangle be represented as ΔABC
Now , the coordinates of the triangle are
A ( 7 , 5 ) , B ( 2 , 9 ) and C ( 1 , 3 )
Now , the triangle is translated 4 units left and 8 units up
To translate the point A(7,5) 4 units to the left and 8 units up, we subtract 4 from the x-coordinate and add 8 to the y-coordinate:
A'(3,13)
To reflect this point across the y-axis, we change the sign of the x-coordinate:
A'(-3,13)
Hence , the translated point is A' ( -3 , 13 )

Which equation represents a line which is perpendicular to the y-axis?
Answers
Answer:
The real answer is y=5
Step-by-step explanation:
because its horizontal
y=5 represents a line which is perpendicular to the y-axis
What is Straight line?A line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects
We need to find the equation which represents a line that is perpendicular to the y-axis
A line perpendicular to the y axis will be a horizontal line, the equation of any horizontal line is y=b where b is the y-intercept.
In the given options
x=-6
y=x-4
y=5
and x=-2y
The only horizontal line is y=5
Hence, y=5 represents a line which is perpendicular to the y-axis
