Need help don't know what to do!

Answers

Answer:

1) 15x+10=130 (corresponding angles)

15x=120

x=120/15

x=8

2) 60+128+x=180 (angle to straight line)

188+x=180

x=180-188

x=-8

3) 12x+8=13x+2

12x-13x=2-8

-x=-6

x=6

4) 115+16x+1=180 (co interior angles)

116+16x=180

16x=180-116

16x=64

x=64/16

How can you use the graph of a quadratic equation to determine the number of real solutions of the equation?​

Answers

Answer:

Step-by-step explanation:

The number of real solution of a quadratic equation can be found from the number of x-intercepts on the graph. If the curve passes through the x-axis twice, (2 x-intercepts), then the equation has two real solutions.

If it passes through once, (the vertex is on x-axis), then there is one real solution, and if it does not touch the x-axis at all (floating above it or below it), then it has no real solutions.

Hope this helped!

2). Bill has twice as many candies as Fred. Tim has 3 fewer than 3 times as many candles as Fred.
In all, they have 177 candies. How many do they each have?

Answers

Step-by-step explanation:

Answer:-

[tex]\tt{Let \ the \ candies \ taken \ by \ Fred \ be \ x.}[/tex]

Now, let's Solve!

So, according to Question,

Bill = 2x

Tim = 3x-3

Total Candies = 177.

[tex]\bf{x+2x+3x-3=177}[/tex]

Totalling x,

[tex]\bf{6x-3=177}[/tex]

[tex]\bf{6x=177+3}[/tex]

[tex]\bf{6x = 180}[/tex]

[tex]\boxed{\sf{x = 30}}[/tex]

So, Fred has 30 candies.

Bill's Candies = 2×30 = 60 Candies

Tim's Candies = 3×30-3 = 90-3 = 87 Candies.
