Step-by-step explanation:
2(x+3) = 5x + 6 - 3x is it true or false
Answer:
True
Step-by-step explanation:
2(x+3) = 5x+6-3x
2x+6=5x-3x+6
2x+6=2x+6
Answer
True
Step-by-step explanation:
Cause 2×X=2x and 2×3=6
so total = 2× + 6 =5× + 6 - 3x
or, 2x + 6 = 5x - 3x + 6
or, 2x + 6 = 2x + 6
The attendance office creates a bar graph to display the number of students tardy throughout the month. What is the range of the number of students tardy during the first five months of the year?
Answer:
60
Step-by-step explanation:
To find the range you subtract the highest and lowest value
The highest value on this graph is 105 from the month of May and the lowest value is 45 from the month of March.
When you do 105-45 you get 60 which is the range

Answer:
(24,4,84)
Step-by-step explanation:
Since they restricted our domains to certain x values, we can find the range by plugging in the x values to find it y value or output.
[tex]f( - 2) = 5( { - 2}^{2} ) + 4[/tex]
[tex]5(4) + 4 = 24[/tex]
[tex]f(0) = - 5( {0}^{2} ) + 4 = 4[/tex]
[tex]5(4) {}^{2} + 4 = 84[/tex]
So our range is (24,4,84)
Answer:
f(x)=5x²+4
f(-2)=5×(-2)²+4
5×4+424f(0)=5(0)²+4
0+44f(4)=5×(4)²+4
5×16+484so the range of function{-2,0,4}is{24,4,85}

Mark's father was putting in a new kitchen floor. The dimensions were 8 feet by 12 feet. If each tile was 1 square foot, how many tiles did he need?
Answer:
96 tiles
Step-by-step explanation:
The kitchen floor is rectangular on shape.
The dimensions of the kitchen floor were 8 feet by 12 feet.
Hence, Area of a rectangle = Length × Width
Length = 8ft
Width = 12ft
Hence:
Area = 8ft × 12ft
= 96 ft²
If each tile was 1 square foot, the number of tiles he would need is
1 ft² = 1 tile
96 ft² = x
Cross Multiply
1ft² × x = 96 ft² × 1 tile
x = 96 ft² × 1 tile/1 ft²
x = 96 tiles
Therefore, Mark's father would need 96 tiles

how do you factor y=6x^2-x-2
6 x -2 = -12
-12 = 3, -4
y = 6x^2 + 3x - 4x - 2
y = 3x(2x + 1) - 2(2x + 1)
(2x + 1) (3x - 2) = 0
2x = -1, 3x = 2
x = -1/2, 2/3
pls give brainliest im trying to level up :))
Answer:
(2x+1)(3x-2)
Step-by-step explanation:
Given :-
y = 6x² - x - 2We need to factor out the given expression. For that we may use the middle term splitting method. Taking the equation,
[tex]:\implies[/tex] y = 6x² - x - 2
[tex]:\implies[/tex] y = 6x² - 4x + 3x-2
[tex]:\implies[/tex] y = 2x ( 3x -2) +1( 3x -2)
[tex]:\implies[/tex] y = (2x + 1)(3x -2 )
Hence the required answer is y = (2x+1)(3x-2)what is the answer -4h=-14
The Answer Is H=3.5
have am amazing day <3
Answer:
[tex]h = \frac{7}{2} [/tex]
Step-by-step explanation:
1) Divide both sides by -4.
[tex]h = \frac{ - 14}{ - 4} [/tex]
2) Two negative makes a positive.
[tex]h = \frac{14}{4} [/tex]
3) Simplify 14/4 to 7/2.
[tex]h = \frac{7}{2} [/tex]
Therefor, the answer is 7/2.

Two best friends, Pluto and Goofy, have very different hobbies. Pluto likes to skydive from a height of 24,568 feet. Goofy likes to scuba dive down to a depth of 124 feet. If they participate in their hobbies at the same time, how far apart will these friends be?
Answer:
They are 24, 692 feet aprart
Step-by-step explanation:
Let us assume at the instance we are measuring their position, that Pluto is at the highest point in the air, which is = 24,568 feet, and Goofy is at the lowest point of the sea (that he can go) = 124 feet.
Before we can proceed with the addition, we need to establish a datum, which will serve as the reference point from which the two distances are measured. This definitely is the sea level, because altitude and depth are usually measured above and below sea level.
Pluto's location to the sea level = 24,568 feet
Goofy's Location to the sea level = 124 feet
their distance apart = 24,568 feet + 124 feet =24, 692 feet apart

The two-dot plots below show the number of miles run by 14 students at the beginning and end of the school year.
Answer:
Step-by-step explanation:
From the dot plot of start of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 5
Range of the data set = 10 - 5
= 5 miles
From the dot plot of End of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 6
Range of the data set = 10 - 6
= 4 miles
The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.

Twenty different statistics students are randomly selected. For each of them, their body temperature (C) is measured and their head circumference (cm) is measured. If it is found that r0, does that indicate that there is no association between these two variables? Choose the correct answer below. A. No, because if r0, the variables are in a perfect linear relationship. B. No, because while there is no linear correlation, there may be a relationship that is not linear. C. No, because r does not measure the strength of the relationship, only its direction. D. Yes, because if r0, the variables are completely unrelated.
Answer:
B. No, because while there is no linear correlation, there may be a relationship that is not linear.
Step-by-step explanation:
Relationships between variables are diverse and fitted model of a dataset for each of the models will usually differ. That is the lebl of association between variables for a linear model may differ and better than a quadratic model or an exponential may perform. For r = 0 ; this means no relationship exists between the variables, however , this is the information for the linear model, which clearly depicts that no assicitio exist for the linear fit. A model change could result in a differ and slightly or highly correlated R value.
