−3(2x−3)=−6x+9
Give the answer with the explanation and i will give branliest if you give explanation.
Answer:
All Real Numbers
Step-by-step explanation:
Expand
-6x+9=-6x+9
This holds true for all real numbers x.
Answer:
Infinite amount of solutions
Step-by-step explanation:
Step 1: Write equation
-3(2x - 3) = -6x + 9
Step 2: Solve for x
Distribute -3: -6x + 9 = -6x + 9Subtract 9 on both sides: -6x = -6xDivide both sides by -6: x = xHere, we see that x is infinite amount of solutions. We can plug in any value x and it would render the equation true.

One-half of the sum of 8
can someone help me find the roots of 3x^2+36x+81=0
Answer:
-3 and -9 are the roots.
Step-by-step explanation:
Answer:
x = -9, -3
Step-by-step explanation:
Step 1: Write equation
3x² + 36x + 81 = 0
Step 2: Solve for x
Factor out 3: 3(x² + 12x + 27) = 0Factor quadratic: 3(x + 3)(x + 9) = 0Divide both sides by 3: (x + 3)(x + 9) = 0Solve individual roots: x = -9, -3Step 3: Check
Plug in x to verify it's a solution.
3(-9)² + 36(-9) + 81 = 0
3(81) - 324 + 81 = 0
243 - 243 = 0
0 = 0
3(-3)² + 36(-3) + 81 = 0
3(9) - 108 + 81 = 0
27 - 27 = 0
0 = 0

which process in the water cycle that is not driven by the force of gravity? *
A. infiltiration
B. precipitation
C. evaporation
D. run off
Answer : The answer is option c evaporation
The process in the water cycle that is not driven by the force of gravity is evaporation.
The water cycle is a series of processes that transport water between the earth's water bodies to the atmosphere, and land, including precipitation in the form of rain as well as snow, evaporation, and transpiration to restore water to the atmosphere.
The force of gravity is a universal force of attraction that acts on any matter coming towards the earth's surface.
From the given options, the only option that is not driven by the force of gravity is evaporation.
This is because water substances evaporate upward and not downward the earth's surface.

To get to the dance competition finals, a dancer must average at least 8.5 points on their 4 preliminary dances. The scores for Jodi’s first 3 dances were: 8.9 points, 7.1 points, and 9.2 points.
What is the lowest score that Jodi can get on the last dance and still make the finals?
Show all your work AND justify your steps.
Answer:
She must score an 8.8 or higher
Step-by-step explanation:
The average is the sum of the number divided by the number of numbers
Let x be the score on the 4th dance
The average is
( 8.9+7.1+ 9.2+x)/4
This must be at least 8.5
( 8.9+7.1+ 9.2+x)/4≥ 8.5
Multiply by 4
( 8.9+7.1+ 9.2+x)/4*4≥ 8.5*4
( 8.9+7.1+ 9.2+x)≥ 34
Combine like terms
( 25.2+x)≥ 34
Subtract 25.2 from each side
( 25.2-25.2+x)≥ 34-25.2
x≥ 8.8
She must score an 8.8 or higher

Which numbers are solutions of 7a−6=a2+4
Choose exactly two answers that are correct.
2
5
7
10
Answer:
a = 5 ; a = 2Step-by-step explanation:
solve for a from the given equation: 7a - 6 = a² + 4
a² - 7a + 10 = 0
the equation can be solved using quadratic equation: ax² + bx + c = 0
x₁,₂ = - b ± √(b² - 4ac)
2a
where a = 1
b = -7
c = 10
now, plug in values into the formula:
a₁,₂ = - (-7) ± √(-7² - 4(1)10)
2(1)
a₁ = 7 + 3 = 10 = 5
2 2
a₂ = 7 - 3 = 4 = 2
2 2
therefore, the answer to the equation is:
a = 5 ; a = 2

Jenny made 3 out of every 4 free throws she took. If she took 48 free throws, how many did she make?
Answer:
36 throws
Step-by-step explanation:
Well, here we go.
Jenny made 3/4 of the tosses.
Now, we need to know what is 3/4 of 48.
Did that word "of" trigger something?
If someone says "of" it automatically means multiplication.
Back to the question, though.
Since it's 3/4 of 48, we need to multiply 3/4 x 48
Let's do it!
[tex]\frac{3}{4}[/tex] × [tex]\frac{48}{1}[/tex]
You cancel out 4 and 48, making the equation simplified.
[tex]\frac{3}{1}[/tex] × [tex]\frac{12}{1}[/tex] = [tex]\frac{36}{1}[/tex]
Alright! Almost done.
[tex]\frac{36}{1}[/tex] is also equal to 36, and that's our answer.
how does the quotient compare to the dividend when the divisor is less than 1
Answer:
Greater provided the divisor is positive.
It would be more accurate and clearer to say that when dividing a number which is greater than zero by a number between 0 and 1, then the quotient is greater than the dividend.
If the divisor is negative and the dividend is positive, then the quotient is negative (and so less than the dividend).

Write the slope-intercept form of the equation of each line given the slope and y-intercept.
Answer:
D. y = -³/2x - 1
Step-by-step explanation:
Given that a line has a slope (m) of -³/2, and a y-intercept of -1, an equation of this line in the slope intercept form is given as y = mx + b.
Where,
m = slope of the line = -³/2
b = y-intercept of the line = -1.
Substitute m = -³/2, and b = -1 into y = mx + b to get the equation of the line in slope-intercept form.
Thus, we would have:
y = -³/2x + (-1)
y = -³/2x - 1
