Answer:
It is
-0.5(3x+5)= -1.5x+2.5
Step-by-step explanation:
-0.5(3x+5)
multiply-0.5 with 3x and 5 to get rid of the brackets.
-0.5×3x= -1.5x
-0.5×5= 2.5
-1.5x+2.5
Answer:
Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent. Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.

What is 8 divided by 3526
Answer:
The answer is 4/1763 in fraction
In decimal, the answer is 0.001 rounded to thousandths.
Step-by-step explanation:
If you want to divide this, you will have to make this expression to a fraction
to 8/3526. Divide the highest numerator if the fraction can simplify. It looks like 3526 can only be simplified by being divided by 2. Divide 2 to each side of the fraction. You should get 2/1763 as a fraction.

What is the first step in solving the equation b=r + 27 for r? A Add 21 to both sides. B Subtract 271 from both sides. C Multiply both sides by 2n. D Divide both sides by 27.
Answer:
B. Subtract 2π from both sides.
Step-by-step explanation:
In order to solve for r, you are gonna want to isolate it. To do so, you first have to subtract 2π from both sides.

Mark wants to fence 4 rectangular gardens, each with a length of 9 1/4 feet and a width of 4 1/2 feet. What is the total length of fending Mark needs to
surround all 4 gardens?
Mark needs
feet of fencing

Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula
P = 2(L) + 2(W)
Total Length of the garden =
=
Length = 18.5 feet
Total width of the garden =
=
Width = 9.0 feet
Perimeter of the garden = 18.5 + 9 = 27.5 feet
Mark wants to fence 4 garden
Therefore, 27.5 × 4 = 110 feet.
Mark needs 110 ft. fencing to surround all 4 gardens.

+6x+12, determine the average rate of change of the function over the interval -3\le x \le 5−3≤x≤5.
Answer:
4
Step-by-step explanation:
edge
The average rate of the function is 4.
What is average rate of function?The average rate of change of a function f(x) over an interval [a, b] is defined as the ratio of "change in the function values" to the "change in the endpoints of the interval". i.e., the average rate of change can be calculated using [f(b) - f(a)] / (b - a). In other words, the average rate of change (which is denoted by A(x)) is the "ratio of change in outputs to change in inputs". i.e.,
A(x) = (change in outputs) / (change in inputs)
= Δy / Δx
= [f(b) - f(a)] / (b - a)
given function:
f(x) = -x² + 6x + 12
Now,
let a= -3, b = 5
and, f(b)= -(5*5) + 6*5 + 12
=-25+ 30 +12
= 17
f(a) = -(- 3 * (-3))+6(-3) +12
= -9-18+12
= -15
Now,
f(b)- f(a) / (b-a)
=17 -(-15))/5-(-3)
=32/ 8
=4

Answer:
slope = -1/2
Step-by-step explanation:
From the graph, pick two points:
[tex](x_{1} , y_{1} ) (x_{2} , y_{2} )[/tex]-> (0, -2) and (-4, 0)
Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Answer:
28 or 28.11111 because I don't know if it asked you to round or not.
Step-by-step explanation:
Mean is the average of a group of number added together and divided by the number of number there are.
20+22+25+28+29+30+32+33+34 = 253
Now we will divide by the number of numbers we have there are 9 numbers.
Soooo.

28
Answer:
28 1/9 or 28.1111... (0.1 repeating)
Step-by-step explanation:
20 + 22 = 42
42 + 25 = 67
67 + 28 = 95
95 + 29 = 124
124 + 30 = 154
154 + 32 = 186
186 + 33 = 219
219 + 34 = 253
253 / 9 = 28 1/9 or 28.11111...
