-3 - 3x = -4(2x + 7)
Answer : x=−5
Step-by-step explanation: Step 1: Simplify both sides of the equation.
−3−3x=−4(2x+7)
−3+−3x=(−4)(2x)+(−4)(7)(Distribute)
−3+−3x=−8x+−28
−3x−3=−8x−28
Step 2: Add 8x to both sides.
−3x−3+8x=−8x−28+8x
5x−3=−28
Step 3: Add 3 to both sides.
5x−3+3=−28+3
5x=−25
Step 4: Divide both sides by 5.
5x /5 = −25 /5
x=−5
Answer:

8. Fill in the blank. The ___
form of the equation of a line with a slope
m passing through (x1y1) is y- y1= m(x-x1).
answer this equation-3x+2<8
Answer:
x > -2
Step-by-step explanation:
-3x+2<8
Subtract 2 from each side
-3x+2-2<8-2
-3x<6
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 6/-3
x > -2
Hey there!☺
[tex]Answer:\boxed{x>-2}[/tex]
[tex]Explanation:[/tex]
[tex]-3x+2<8[/tex]
Let's subtract 2 from both sides of the inequality.
[tex]-3x+2-2<8-2\\-3x<6[/tex]
Now divide both sides by -3.
[tex]\frac{-3x}{-3}<\frac{6}{-3}[/tex]
Simplify 6/-3. Also remember that dividing a positive with a negative will give us a negative.
[tex]6/-3=-2[/tex]
[tex]x>-2[/tex]

The perimeter of the triangle is 13 inches. What is the length of the shortest side?
Answer:
3 in
Step-by-step explanation:
Sum of all sides of ∆ = perimeter
Given that it has a perimeter of 13 in, and the following sides: (x - 5) in, x/2 in, and 6 in, therefore:
[tex] x - 5 + \frac{x}{2} + 6 = 13 [/tex]
Solve to find the value of x
[tex] \frac{2x - 10 + x + 12}{2} = 13 [/tex]
[tex] \frac{3x + 2}{2} = 13 [/tex]
Multiply both sides by 2
[tex] \frac{3x + 2}{2}*2 = 13*2 [/tex]
[tex] 3x + 2 = 26 [/tex]
Subtract 2 from both sides
[tex] 3x + 2 - 2 = 26 - 2 [/tex]
[tex] 3x = 24 [/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{24}{3} [/tex]
[tex] x = 8 [/tex]
The shortest side = (x - 5) in
Plug in the value of x
= (8 - 5) in
= 3 in

Which function below is the inverse of f(x)= 3x+5/7
Answer:
[tex]\huge\boxed{f^{-1}(x) = \frac{7x-5}{3}}[/tex]
Step-by-step explanation:
Given the function:
[tex]f(x) = \frac{3x+5}{7}[/tex]
Put f(x) = y
[tex]y = \frac{3x+5}{7}[/tex]
Interchange x and y
[tex]x = \frac{3y+5}{7}[/tex]
Solve for y
[tex]x = \frac{3y+5}{7}[/tex]
Multiplying both sides by 7
[tex]7x = 3y+5[/tex]
Subtracting y to both sides
[tex]7x-5 = 3y[/tex]
Dividing both sides by 3
[tex]\frac{7x-5}{3} = y[/tex]
OR
[tex]y = \frac{7x-5}{3}[/tex]
Put y = [tex]f^{-1}(x)[/tex]
So,
[tex]f^{-1}(x) = \frac{7x-5}{3}[/tex]

What is quadrilateral?A closed quadrilateral is a form of polygon with four sides, four vertices, and four angles. Four non-collinear points are joined to create it. Quadrilaterals' internal angles add up to a constant 360 degrees.
In the given quadrilateral,
Side AD = 8X - 1, CD = 6X + 9
And AB = 3x - 2
According to given diagram,
AD = CD
8x -1 = 6x + 9
2x = 9 + 1
2x = 10
x = 5
The length of side AB = 3x - 2 = 3 (5) - 2 = 15 - 2 = 13
The figure ABCD is a symmetrical figure,
Therefore,
AB = BC
AB = BC = 13
The required side AC = AB + BC
= 13 + 13
= 26
The length of the side AC is 26 units.

When cut into 16 equal slices, each slice is 1/16 of the pizza. Express how much of the plzza 8 of these slices would be in decimal form.
Answer:
the answer is 0.5, or about 50%
Step-by-step explanation:
If 8 slices are being take out of 16, divide the taken pieces by the total pieces, and it would be half or 0.5.
Hope this helps
Answer: 0.5
Step-by-step explanation: because if the pizza is 8 slices that would be the half of the original number of slices it was, so therefore, it would be rounded to 0.5, or 50%- half the pizza

z=-3.
Solve for x in simplest form. 9=8/5(x+5)
Answer:
5/8 =x
Step-by-step explanation:
9=8/5(x+5)
Multiply each side by 5
5* 9=5*8/5(x+5)
45 = 8(x+5)
Distribute
45 = 8x+40
Subtract 40 from each side
45-40 = 8x+40-40
5 = 8x
Divide each side by 8
5/8 = 8x/8
5/8 =x
