What is an equation of the line that passes through the point (-4,-6) and is perpendicular to the line 4x+5y=25?
Answers
Answer:
y= 5\4x - 1
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
First, rewrite the equation of the given line in the form of y=mx +c.
4X+5y=25
5y= -4X +25
y= -4\5X +5
The gradient of the given line is -4\5
The product of the gradient of perpendicular lines is -1.
(14\5)(gradient of the line) = -1
gradient of the line= -1 divided by (-4\5)
Thus, m=5\4
y=5\4x +C
Substitute a coordinate to find c.
When X= -4, y= -6,
-6 =5\4 (-4) +C
-6= -5 +C
C= 5-6
C= -1
Hence, the equation of the line is
y= 5\4x - 1

All three angles of a triangle add to 180°. You are given that one angle is 42° and for a isosceles triangle, the two remaining angles in the photo are equal so:
180° = 2x - 42°
138° = 2x
x = 69°

ASAP: Which equation best represents the line of best fit for the data in the scatterplot above?
Answers
Answer:
F : y = -x + 4
Step-by-step explanation:
The first observation about this scatterplot is that the best line of fit will be a line going diagonally from top left to bottom right(or bottom right to top left)
Such a line has negative slope
Equation will be of the form
y = mx + b where m is a negative number
We can eliminate H and I since both lines have a positive slope which means that the line will go in a diagonal bottom left to top right direction
Let's examine options F and G
F: y = - x + 4
G: -9x + 3
Plug in some values for x from the graph and see which of the lines comes closest to the y values computed from the equations
At x = -5, the y value from the graph appears to be either 7 or 8
F: y = -x + 4 ==> -(-5) + 4 = 5 + 4 = 9; pretty close to graph's point value
G: -9x + 3 ==> -9(-5) + 3 = 45 + 3 = 48; this is greatly different from the graph value
At x = 0; the y value from graph is close to 4
From the equations we get
F: y = -x + 4 ==> y = -(0) + 4 = 4; pretty darn close
G: y -9x + 3 => y = -9 + 3 = -6; large difference
One more point
At x = 20, the point on the graph appears to be close to -19
From the equations we get
F: y = -x + 4 = -20 + 4 = -16; not too different
G: y = -9x + 3 = -9(20) + 3 = -180 + 3 = 177; way off
So the best line of fit would be
F : y = -x + 4
The equation that best represents the line of fit from the scatter plot is given as follows:
y = -x + 4.
How to define a linear function?The slope-intercept representation of a linear function is given by the equation shown as follows:
y = mx + b
The coefficients m and b have the meaning presented as follows:
m is the slope of the function, representing the increase/decrease in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, representing the numeric value of the function when the input variable x has a value of 0. On a graph, it is the value of y when the graph of the function crosses or touches the y-axis.From the scatter plot, we have that when x = 0, y = 4, hence the intercept b is given as follows:
b = 4.
When x = 20, y is approximately -16, hence the slope m is obtained as follows:
-16 = 20m + 4
20m = -20
m = -1.
Hence the function is:
y = -x + 4.

Answers
Answer:
58
Step-by-step explanation:
Ok So do you see the right angle square that equals 90 so all you have to do is subtract 32 from 90 which is 58
So the angle where 32 and x are in show the 90 degree angle line, so you would subtract 32 from 90; 90-32= 58
Explaining the other points , you would use the same process. A whole thing is 360 degrees
It is broken up by one straight line the breaks them into 2 sections of 180
The bottom one has a known value of 120
180-120=60
The top one is divided into three parts, and one is a divided 90 angle, so the other side would be 90 degrees

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles. Suppose a star is 13.4 light-years from Earth. In scientific notation, how many miles away is it? 7.8792 x 1013 miles 1.34 x 1012 miles 5.88 x 1012 miles 5.88 x 1013 miles
Answers
Explanation: We need to make a proportion to figure out the miles.
1 light year/5,880,000,000,000 miles=13.4 light years/x miles.
After cross multiplying (1 by x and 5800...by 13.4), we have x=7.8792*10^13
Also, the answer before setting it in scientific notation was 78.792 trillion and we moved the decimal 13 times to get to 7, which is between 1 and 10.

The probability that a sequence will contain exactly one zero is true in options {B}, {C} and {D}.
We can write the formula for probability as -
P{Event} = (no. of favorable outcomes)/(Total no. of favorable outcomes)
For the sequence {A} -
000, 001, 010, 011, 100, 101, 110, 111
P{one zero} ≠ 7/8
For the sequence {B} -
001, 011, 101, 111
P{one zero} = 7/8
For the sequence {C} -
000, 010, 011, 101, 111
P{one zero} = 2/8
For the sequence {C} -
000, 001, 010, 011, 100, 101, 110, 111
P{one zero} = 3/8
