Is 1 + 4(3x - 10) - 12x equivalent to -9? EXPLAIN and show your work.
Answer:
Since you have to distribute the 4 to both terms in parentheses, the equation is simplified like this:
1 + 12x - 40 -12x
= 1 - 40
= -39
Step-by-step explanation:
Answer: No
Step-by-step explanation:
1 + 4(3x - 10) - 12x = 9
simplifies to
1+12x - 40 -12x =9
combine like terms to get
-39 = 9
This is not possible so the answer is no.

Question: Detereme the intercepts of the line
y - intercept ( , ) ( , )
x - intercept ( , ) ( , )
Answer:
y= (-40,-1) x=(-10-17)
Step-by-step explanation:
please help and can someone explain what a integer is
w = -18
x = -10
y = -2
z = 10
x and z are opposite, x= -10, where as z = 10, Hence x times (-1) equals z.
An integer is a non-fractional number real number. It can be either negative or positive, it simply cannot be a fraction.
"w", "x", and "y" are negative, and hence less than zero.

If P=(-3,4), find: Rx-axis (P)
Answer:
(-3,-4)
If it was on the y-axis it would be (3,4)
Step-by-step explanation:
Rx-axis (P) = (-3, -4)
What is reflection about x-axis?"When we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol."
For given example,
we have been given a point P = (-3, 4)
We need to find Rx-axis (P)
That is we need to reflect given point about x-axis.
We know, when we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol.
So, the reflected point would be (-3, -4)
Therefore, Rx-axis (P) = (-3, -4)

Prove that the triangle with vertices A(0,1), B(3,3), and C(3,-1) is an isosceles triangle. Select the two sides that are congruent.
Answer:
AB and AC are congruent
Step-by-step explanation:
To show that the triangle is isosceles, we need to show that two of the sides of the triangle are equal.
Get AB
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
A(0,1), B(3,3)
AB = √(3-0)²+(3-1)²
AB = √3²+2²
AB = √9+4
AB = √13
Get BC
B(3,3), and C(3,-1)
BC = √(3-3)²+(-1-3)²
BC = √0²+-4²
BC= √0+16
BC = √16
BC = 4
Get AC
A(0,1), and C(3,-1)
AC = √(3-0)²+(-1-1)²
AC = √3²+(-2)²
AC = √9+4
AC= √13
Since AB = AC, this shows that the triangle ABC is an isosceles triangle.
The two sides that are congruent are AB and AC
