Identify the slope and y-intercept of the line y = 9x - 3
Answer:
slope = 9 , y- intercept = - 3
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 )
y = 9x - 3 ← is in slope- intercept form
with slope m = 9 and y- intercept c = - 3
Two cyclists start from 98 miles apart and begin racing toward each
other. Three hours later, they have not yet met and the distance between
them is 2 miles. How fast is each of them biking if one bikes 3 mph
slower than the other?
The speed of one bicyclist was 14.5mph, speed of the other bicyclist was 17.5mph.
Let the speed of one bicyclist=x mph
Let the speed of the other bicyclist=(x+3) mph
Hence:
Speed of one bicyclist:
3x+3(x+3)+2=98
3x+3x+9+2=98
6x=87
Divide both side by 6x
x=87/6
x=14.5 mph
Speed of the other bicyclist:
x+3 mph
14.5 mph+3 mph
=17.5 mph
Inconclusion the speed of one bicyclist was 14.5mph, speed of the other bicyclist was 17.5mph.

What is w(53)is equal to
Answer:
Step-by-step explanation:
The question is slightly ambiguous. The problem is, do you find the first 40 hours using 10x and then the second equation using x >40. I don't think so, but it should be made clear. It turns out that the first 40 hours does equal 400 so that you can use the second expression with no worries.
w(53) = 15(53 - 40) + 400
w(53) = 15(13) + 400
w(53) = 195 + 400
w(53) = 595

Enter your answer as a fraction, formatted like this: 42/53
Or, if the slope is undefined, enter a lowercase letter "u," like this: u
Answer:
-1/2
Step-by-step explanation:
To find the slope, you use the rise/run method.
To get from one point to another, you would move 1 unit down (rise) and 2 units to the right (left)
The slope would be -1/2

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The value of d is -4 - 8i
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
2x + 6 is an equation.
We have,
Two equations:
c - d = 7 _______(1)
c = 3 - 8i _______(2)
We are using the substitution method to solve this problem.
We make the value of a variable from an equation and substitute the value of that variable in the other equation.
From (1) we get,
c - d = 7
Add d on both sides.
c - d + d = 7 + d
c = 7 + d ______(3)
Put (3) on (2) we get,
7 + d = 3 - 8i
Subtract 7 on both sides.
7 + d - 7 = 3 - 8i - 7
d = -4 - 8i
Thus,
If,
c - d = 7
c = 3 - 8i
The value of d is -4 - 8i

Find the size of LZ.
PLEASE HELP ILL PAY U $10
Answer:
Angle Z is 70 degrees
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees. Angle x is 45, angle y is 65.
180-45-65 = 180-110 = 70
The two triangles shown are congruent
Answer:
30* or A
Step-by-step explanation:
If the triangles are congruent, corresponding angles and sides are equal.
So angle c is 60* because it is opposite of side x.
angle b is 180-90-60 because all angles add up to 180 in a triangle.
