2. Three times the sum of a number and 4 is 21
less than the number times 6. Find the number
Answer:
11
Step-by-step explanation:
Given two expressions involving the same unknown number, you want to find the number.
Setup3(x +4) . . . . three times the sum of a number and 4
6x -21 . . . . 21 less than the number times 6
These two expressions have the same value, so we can write the equation ...
3(x +4) = 6x -21
SolutionEliminating parentheses, we have ...
3x +12 = 6x -21
33 = 3x . . . . . . . . add 21-3x
11 = x . . . . . . . . . divide by 3
The number is 11.

Graph y = x² + 1 by plotting the points for x = -1,0, 1 and drawing the curve.
Provide your answer below:
Answer: The points are
(-1,2)
(0,1)
(1,2)
The graph is below
=========================================================
Explanation:
The idea is to replace x with the values mentioned (one at a time) and find the paired y value
For example, if x = -1, then...
y = x² + 1
y = (-1)² + 1
y = 1 + 1
y = 2
So (-1,2) is one point on the parabola. Follow similar steps to find the other points (0,1) and (1,2)

what is factorization?when you break a number down into smaller numbers that, multiplied together, give you that original number.
Given:

=x+ 10/ 2x(x-4)
D: 6x³ + 42x²/2x² + 26x +84

which is true about the degree of the sum and diffrence of the polynomials 3x^5y-2x^3y^4-7xy^3 and -8x^5y+2x^3y^4+xy^3?
The degree of the sum of the polynomials is 6 while the degree of the difference of the polynomial is 7.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A polynomial's degree is the highest exponent of a variable in a polynomial equation.
Given the polynomial 3x⁵y - 2x³y⁴ - 7xy³ and -8x⁵y + 2x³y⁴ + xy³
The sum of the polynomials = (3x⁵y - 2x³y⁴ - 7xy³) + (-8x⁵y + 2x³y⁴ + xy³) = -5x⁵y - 6xy³
The difference of the polynomials = (3x⁵y - 2x³y⁴ - 7xy³) - (-8x⁵y + 2x³y⁴ + xy³) = 11x⁵y - 4x³y⁴ - 8xy³

The integer 5 makes which of the following equations false?
A: 3m + 4 = 6m
B: −5(t − 7) = 10
C: 17 = 4x − 3
D: t + 9 = 14
Answer:
a) 3m + 4 = 6m is false.
Step-by-step explanation:
A) 3m + 4 = 6m
→ 3(6) + 4 = 6(5)
→ 18 + 4 = 30
→ [ 22 ≠ 30 ]
So, the equation is false.
B) -5(t - 7) = 10
→ -5(5 - 7) = 10
→ -5 × -2 = 10
→ [ 10 = 10 ]
So, the equation is true.
C) 17 = 4x - 3
→ 17 = 4(5) - 3
→ 17 = 20 - 3
→ [ 17 = 17 ]
So, the equation is true.
D) t + 9 = 14
→ 5 + 9 = 14
→ [ 14 = 14 ]
So, the equation is true.

The possible row arrangements for the football cheerleaders are (4×4) or (8×2).
What is termed as factorization?When you factorize a number, you divide it into smaller numbers that, when multiplied together, offer you the original number. Factorization occurs when you divide a number in with its factors or divisors. For example, the factorization of a number 12 could be 3 times 4.For the given expression.
The total of football cheerleaders = 16.
Each row consists of same number of cheerleaders.
For, this find the factors of 16;

On the other hand, low-cost manufactured items are produced and exported by China, Thailand, and Vietnam. These three nations enjoy a distinct advantage as a result of their significantly reduced unit labor costs.

One example can be:
"Amount of sugar that you put in your coffee and the calories of that coffee."
Where:
independent variable = amount of sugar.dependent variable = amount of calories.How to identify two related variables?
Any two quantities that are related in any way are related variables.
Some examples are:
Time driving your car at constant speed and the distance that you travel in that time. Time that you put food in the oven and the temperature of the food when you take it out.Amount of sugar that you put in your coffee and the calories of that coffee.etc...
The independent variable is the one that we can control, and the dependent variable is the one that changes in response to the independent one.
In the last example, the independent variable is the amount of sugar that you put in your coffee because you decide how many spoons you want.
And the dependent variable is the amount of calories in that coffee, that will depend on how much sugar you put there.

The scale of a map is 1:500 000.
The area of a lake on the map is 12cm".
Calculate the actual area of the lake in km?.
The scale of a map is 1:500 000. The actual area of the lake in km is 3x10¹² km².
What is meant by the scaling on the map?The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult.
• If 1 centimeter on a map corresponds to 500 000 km on the earth, then 1 cm2 would be equivalent to 1 cm² = (500000km) 2
=25×10¹⁰ km²
• The lake's exact area may now be determined by multiplying 12 cm² by 25 × 10¹⁰ km² (3 × 10¹² km²)
As a result, the distance between the towns is 0.000344 cm on the map, while the lake's real area is 3x10¹² km².

Step-by-step explanation:
Let's solve your equation step-by-step.
(x−5)²=3
Step 1: Simplify both sides of the equation.
x²−10x+25=3
Step 2: Subtract 3 from both sides.
x²−10x+25−3=3−3
x²−10x+22=0
For this equation: a=1, b=-10, c=22
