Answer:
x = [tex]\frac{2b+3}{5b-2}[/tex]
Step-by-step explanation:
Given
x(5b - 2) = 2b + 3 ← isolate x by dividing both sides by (5b - 2)
x = [tex]\frac{2b+3}{5b-2}[/tex]

simplify the exoression (x^3-5x^2+7x-12)÷(x-4)
Answer:
x^2-x+3
Step-by-step explanation:
You factor it out which would then make it
(x-4)(x^2-x+3)/x-4
Then you cancel out the common factor, x-4
which leaves you with x^2-x+3
Dominique and Ella are comparing whose jet traveled faster. The graph shows the relationship between the total distance Dominique traveled and the time in hours. The distance Ella traveled after x hours can be represented by the equation y=550x.
Who if anyone, traveled at a faster speed? Explain.
Answer:
Ella
Step-by-step explanation
Ella travelled faster than Dominique by 50 miles/hr.
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have Dominique and Ella are comparing whose jet traveled faster.
The speed of the jet will be equivalent to slope of the line representing the motions.
Dominique's speed = (2200 - 1100)/(4 - 2) = 1000/2 = 500 miles/hr
Ella's equation of motion -
y = 550x
Ella's speed = 550 miles/hr
Therefore, Ella travelled faster than Dominique by 50 miles/hr.

a right angle is formed by the x-axis, and the line y = -3x + 6. what is the length of the hypotenuse?
Answer:
The length of the hypotenuse is [tex]2\sqrt{10}[/tex] ≅ 6.325
Step-by-step explanation:
∵ A right angle is formed by the x-axis, y-axis and the line y = -3x + 6
∴ The line intersected the x-axis at point (x, 0)
→ To find x substitute y in the equation by 0
∵ 0 = -3x + 6
→ Add 3x to both sides
∴ 0 + 3x = -3x + 3x + 6
∴ 3x = 6
→ Divide both sides by 3
∵ [tex]\frac{3x}{3}=\frac{6}{3}[/tex]
∴ x = 2
∴ The line intersected the x-axis at point (2, 0)
∵ The line intersected the y-axis at point (0, y)
→ Substitute x in the equation by 0 to find y
∴ y = -3(0) + 6
∵ y = 0 + 6
∴ y = 6
∴ The line intersected the xyaxis at point (0, 6)
∵ The endpoints of the hypotenuse are (2, 0) and (0, 6)
→ Use the rule of the distance d = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex] to find it
∵ x1 = 2 and y1 = 0
∵ x2 = 0 and y2 = 6
∴ h = [tex]\sqrt{(0-2)^{2}+(6-0)^{2}}=\sqrt{4+36}=\sqrt{40}=2\sqrt{10}[/tex]
∴ The length of the hypotenuse is [tex]2\sqrt{10}[/tex] ≅ 6.325

Brenda has two pieces of string, one 28 feet long and the other 42 feet long. For an art project, she wants to cut them up to produce many pieces of string that are all of the same length, with no string left over. What is the greatest length, in feet, that she can make them?
Answer:
7 feet
Step-by-step explanation:
Length of one piece of string = 28 feet.
Length of the second string = 42 feet.
Since the number of required pieces was not given but many are required, the greatest length can be determined by;
If the maximum length is 7 feet, then:
the number of pieces from 28 feet long string = [tex]\frac{28}{7}[/tex]
= 4
Also,
the number of pieces from the 42 feet lone string = [tex]\frac{42}{7}[/tex]
= 6
Total number of 7 feet strings that she can make = 4 + 6
= 10
Since many pieces are required, the greatest length she can make is 7 feet. If she increase the length to 14 feet, the number of pieces would be 5 which limit the required number.

Answer:
x=10
Step-by-step explanation:
Perimiter is 2(x+y) with x and y being the two differend sides. First side is 3x and the second is 2x+4. 2(3x+2x+4)=108. 10x+8=108 10x=100 x=10.
The sides are 24 and 30
Please mark brainliest hope this helps :D
Answer:
x=10
Step-by-step explanation:
Since this is a rectangle, we know that the values of opposite sides are equal and that the perimeter is all of the sides' values combined. Therefore:
2(2x+4)+2(3x)=108
First, we need to distribute the 2s on the left side.
4x+8+6x=108
Combine like terms.
10x+8=108
Subtract the 8 from both sides.
10x=100
Divide by 10.
x=10

Mario runs a yard company. He charges $20 to show up for the job and $4 for each 10 square Yards. His competition, Linda's Lawn Care, charges $10 for showing up and $6 for each square 10 yards. After how many 10 square yards are, they charging the same? And how much is charged at that moment?
Answer:
5 square 10 yards
$40
Step-by-step explanation:
Mario:
20 + 4x
Her competitor:
10 + 6x
Where,
x = number of 10 square yards
Equate the expressions
20 + 4x = 10 + 6x
Collect like terms
20 - 10 = 6x - 4x
10 =2x
Divide both sides by 2
x = 10 / 2
= 5
x = 5 square 10 yards.
Charge at that moment
Using any of the cost equation
10 + 6x
= 10 + 6(5)
= 10 + 30
= 40
$40
Or
20 + 4x
= 20 + 4(5)
= 20 + 20
= $40

What is the slope of the line through the points (0,-3) and (2,1)?
Answer:
alright so you got 2 points! now this is the slope formula! y2-y1/x2-x1
okay let's label your points! (x1 0,y1 -3) (x2 2,y2 1)
let's follow the formula this makes it so we can solve! 1--3/2-0
I understand you may get a decimal but don't use 2.5 use a fraction because teachers seem to like fractions and general decimals can be hard to use (experience lol) 2.5 is 5/2 so this means your slope is 5/2
this formula works every single time and if you memorize it you can do any other problems with 2 points! please memorize y2-y1/x2-x1

Point P′(−3, 2) is the image of point
P(3, 8) under a translation. What
is the image of (0, −6) under the
same translation?
Answer:
The image of (0, -6) after the same transformation is (-6, -12)
Step-by-step explanation:
After the required translation, the given image of the given point P(3, 8) is P'(-3, 2)
Therefore, the translation of preimage P(3, 8) to the image P'(-3, 2) is given by the difference between the coordinates as follows;
The translation from P(3, 8) to P'(-3, 2) = T(-3 - 3, 2 - 8) = T(-6, -6)
Therefore after the same translation, the preimage of (0, -6) will have an image given as follows;
Coordinate of preimage (0, -6) → T(-6, -6) (0, -6) = (0+ -6, -6 + -6) → Coordinate of image (-6, -12)
The image of (0, -6) after the same transformation = (-6, -12).

evaluate when, x = -6
Substitute in -6, for x,
-10(-6)^(4) - 9(-6)^(2) - 8(-6) + 8
= -10(1296) -9(36) -8(-6) + 8
