No.
The three angles of a triangle need to add up to 180 degrees, this means no one angle can be 180 degrees.

Mark incorrectly solved the inequality -4(5/2+3/2x) > 8. His work is shown. Which step shows an error based on the inequality

aliya0001 [1]

Answer : The incorrect step is, (A) step 1: -10 + 6x > 8

Step-by-step explanation :

The given expression is:

$-4(\frac{5}{2}+\frac{3}{2}x)>8$

Now solving this expression step by step.

First -4 distributed over parentheses.

$(-4\times \frac{5}{2})+(-4\times \frac{3}{2}x)>8$

Now solving bracket term, we get:

$-10-6x>8$

Now taking like terms together, we get:

$-6x>8+10$

$-6x>18$

$-x>3$

Now multiplying this expression by (-1), we get:

$x>-3$

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8

Answer:

hope it helps

Step-by-step explanation:

4x-3=2x+25

step1: you collect like terms by crossing over values that are of the same kind and their signs also change as they cross the equal to sign

4x-2x=25+3

2x=28

step2: in order to find the value of x, you need to make it the subject of formula, which can be done by dividing the coefficient of x by itself on both sides

2x/2=28/2

x= 14

What is the solution set to the following system?<br> X+y=4<br> X^2+y^2=16

faltersainse [42]

X+y = 4, -----> y=4 - x
x² +(4-x)² =16
x² +16-2*4x+x² =16
2x² - 8x = 0
x(2x-8) = 0
2x-4=0, 2x=8, x=4
x=0 or x=4

If x=0, y=4-x=4-0=4.
If x=4, y= 4-x=4-4=0.

(0,4) or (4,0)

Check
x² +y² =16
For (0,4)
0²+4² =16
16 =16 True

For (4,0)
4² +0²=16
16=16 True

Answer (0, 4) and (4,0).
