Given:
The equation is
[tex]-3(2x-3)=33[/tex]
The incorrect solution steps are given.
To find:
The first error.
Solution:
We have,
[tex]-3(2x-3)=33[/tex]
Using distributive property, we get
[tex]-3(2x)-3(-3)=33[/tex]
[tex]-6x+9=33[/tex]
The given step 1 is [tex]-6x+6=33[/tex], which is not correct.
Therefore, there is first error in step 1 because the distribution property is not used properly.
Hence, the correct option is D.

Triangle JKL is rotated to 270° counterclockwise about the origin to form triangle JKL what is the Y coordinate of point J?
Answer:
J' = (-2, 4)
Step-by-step explanation:
The transformation for 270° counterclockwise rotation about the origin is ...
(x, y) ⇒ (y, -x)
The point J is (-4, -2), so the point J' is ...
J' = (-2, -(-4))
J' = (-2, 4)

What is product of 5.2 · 10^6 and 1.4 · 10^3
Answer:
7280000000 or 7.28^9 (in scientific notation)
Step-by-step explanation:
this question is asking you to transfer numbers out of scientific notation and multiply them. 10^6 is 1 followed by 6 zeros (good trick to remember) or 1000000. when you multiply anything by a power of 10 you just add that many zeroes to it or move the decimal point one point to the left for every zero. so in this example it is 5.2 times 1000000 which is 5200000. we do the same for the other one and we get 1400. When we multiply these two values we get 7280000000 or 7.28^9

7x-1+6x=90
What is the answer?
Answer:
x = 7
Step-by-step explanation:
7x-1+6x=90
Combine like terms
13x-1 = 90
Add 1 to each side
13x-1+1 = 90+1
13x = 91
Divide by 13
13x/13 =91/13
x = 7
Help please I really need to solve for x
[tex](6 - 2) \times 180 = 4 \times 180 = 720 \\ [/tex]
So the sum of the nterior angles of the figure must equal 720° :
[tex](x - 8) + 4x + 2x + 3x + 2x + 2x = 720 \\ [/tex]
[tex]14x - 8 = 720[/tex]
Plus both sides 8
[tex]14x = 728[/tex]
Divided both sides by 14
[tex]x = \frac{728}{14} = 52 \\ [/tex]
So ;
[tex]x = 52[/tex]

help please! I just want to actually get my homework done
Answer:
72/b = h
Step-by-step explanation:
plug in known values
A = 1/2 (bh)
36 = 1/2 (bh)
goal is to isolate the variable h (height)
multiply both sides by 2 to cancel out 1/2
36 × 2 = 1/2 × 2 (bh)
72 = bh
divide both sides by b (base)
72/b = bh ÷ b
72/b = h
i dont see the value for base given so this would be the final answer as far as i know
What is greater, 3 pi or 9?
Answer:
3 pi is greater
Step-by-step explanation:
I don't know the exact amount of pi so I can't multiply it, but I do know that it starts with 3.14159 which is greater than 3 (which is what you have to multiply by 3 to get 9) so the amount will be larger than nine.

Congruent triangles are similar triangles.
The statement that completes the proof is [tex]\mathbf{\angle ACB \cong ECD}[/tex]
From the complete question (see attachment), we have the following highlights
[tex]\mathbf{AC\cong CE}[/tex].[tex]\mathbf{BC\cong CD}[/tex]The angle at point C of both triangles are congruent
i.e. [tex]\mathbf{\angle ACB \cong ECD}[/tex]
This means that the missing statement of the proof is that the angles at C of both triangles are congruent.

Write an equation perpendicular to y = -2x - 7 that passes through the point (4,3)
The equation of line perpendicular to the line y = -2x-7 passing through (4,3) is : 2y = x+2
What is slope of line ?
Slope of line is the angle made by the line from positive x-axis in anticlockwise direction, it also denoted the steepness of the line.
Here, the equation of line given is y = -2x-7 first calculating its slope ([tex]m_{1}[/tex]) by comparing it with slope- intercept form of line i.e. y = mx+c
Therefore, the slope of the given line [tex]m_{1}[/tex] is -2.
Now the slope ([tex]m_{2}[/tex]) of the line perpendicular to the given line is calculated using relation :
[tex]\begin{aligned}m_{1}m_{2}&=-1\\m_{2}&=\frac{-1}{-2}\\&=\frac{1}{2}\end{aligned}[/tex]
Now the equation of the line passing through (4,3) and slope 1/2 will satisfy the equation y = mx +c
[tex]\begin{aligned}y&= mx +c \\3&=\frac{1}{2}\cdot 4+c\\c&=1\end{aligned}[/tex]
Therefore the equation of line perpendicular to the line y = -2x-7 passing through (4,3) is : 2y = x+2
[tex]\begin{aligned}y&= mx +c \\y&=\frac{1}{2}x+1\\2y&=x+2\end{aligned}[/tex]

=======================================================
Explanation:
The angles (2x+24) and x are same side interior angles. Same side interior angles are supplementary when we have parallel lines.
(2x+24) + (x) = 180
2x+24+x = 180
3x+24 = 180
3x = 180-24
3x = 156
x = 156/3
x = 52
