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

Answer:

There are two solutions for x;

x = 0

x = [tex]-\frac{3}{2}[/tex]

Step-by-step explanation:

Answer:

x = 0 or -3/2

Step-by-step explanation:

( 2 x +  3 ) ^2  −  6 x −  9  =  0 ---> distribute

4x^2 + 6x + 6x + 9 - 6x - 9 = 0 --> add the 9's together

4x^2 + 12x  - 6x = 0 --> combine like terms

4x^2 + 6x = 0 --> common factor

2(2x^2 + 3x) = 0 --> divide by 2 on both sides

2x^2 + 3x = 0

then you should use the quadratic formula (can't add here or the explanation would take too long)

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

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.

Answer:

So because the range is between 20 and 40, it can be noticed through counting.

5, 10, 15, 20, 25, 30, 35, 40

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39

The number of balls in the box, just from the information by 5, is either ending in 1 (for example 21, 31) or 6 (26, 36)

From counting by 3 with that information, it would mean the number is most likely 26 balls, since there would be one left when Max reaches 25 counting by 5, and two left when he reaches 24 counting by 3.

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

Answer:

d=-4.......,...........

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

If,

c - d = 7

c = 3 - 8i

The value of  d is -4 - 8i

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

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.
