Jamie draws a triangle he says two of my three angles are obtuse

A triangle's interior angles will always add up to 180 degrees.

When one interior angle gets larger, the other angles must decrease in size.

If you attempt to make a triangle with two obtuse angles, you will find you can't do it in three lines. But you need an extra line in order to close the shape. But it won't be a triangle.

Mr. Gaster has $5 in his piggy bank and wants to put $45 every week into the piggy bank. Make you equation showing how much mone
Romashka-Z-Leto [24]
So your starting amount is 5. Your equation will start like this:
5+
Now 45 dollars a week. So no matter how many weeks you are going to multiply it by 45. So you add that in and you have an equation that looks like this:
5+45x
X stands for the weeks. Then finish it off with your equals:
5+45x=y
Y is the total amount of money. 
The Equation will be. 
5+45x=y

Part 2:

The equation is set up on weeks so you need to find out how many weeks 28 days is. 
28/7=4
 
Now that you know that you can substitute 4 for x. 

5+45*4=y
5+180=y
185=y
He will have 185 dollars in his bank. <span />

What are the solutions to the system of equations?<br> y = 2x² + 6x - 10<br> \ y =<br> y = -x + 5
Akimi4 [234]

Answer:

x= 1.5, y= 3.5

or x= -5, y= 10

Step-by-step explanation:

Let's solve by substitution.

Label the two equations:

y= 2x² +6x -10 -----(1)

y= -x +5 -----(2)

Substitute (2) into (1):

2x² +6x -10= -x +5

2x² +6x +x -10 -5= 0

Simplify:

2x² +7x -15= 0

Factorise:

(2x -3)(x +5)= 0

2x -3= 0 or x +5= 0

2x= 3 or x= -5

x= 1.5

Now that we have found the value of x, we can find the value of y through substitution.

Substitute into (2):

y= -1.5 +5 or y= -(-5) +5

y= 3.5 or y= 10
