11 1303170
11 1000 210
Answer:
Answer is in attached image.
Step-by-step explanation:
Given the expressions, for which we have to find the estimates as per the expressions on the left.
The given expressions are:
1) 35 [tex]\times[/tex] 23
2) 132 [tex]\div[/tex] 168
3) 17.3 [tex]\times[/tex] 18.4
4) 999 [tex]\div[/tex] 208
5) 998 [tex]\times[/tex] 211
Here, we need to find the rounded off numbers.
35 can be rounded to 40 and 23 to 20.
Therefore, equivalent to 35 [tex]\times[/tex] 23 is 40 [tex]\times[/tex] 20
132 can be rounded to 130 and 168 to 170.
Therefore, equivalent to 132 [tex]\div[/tex] 168 is 130 [tex]\div[/tex] 170.
17.3 can be rounded to 17.0 and 18.4 to 18.0.
Therefore, equivalent to 17.3 [tex]\times[/tex] 18.4 is 17.0 [tex]\times[/tex] 18.0.
999 can be rounded to 1000 and 208 to 210.
Therefore, equivalent to 999 [tex]\div[/tex] 208 is 1000 [tex]\div[/tex] 210.
998 can be rounded to 1000 and 211 to 210.
Therefore, equivalent to 998 [tex]\times[/tex] 211 is 1000 [tex]\times[/tex] 210.
The solution can be found in the attached image as well.

2a - 3b = -11
a + 3b = 8
Answer:
b = 3 and a = -1
Step-by-step explanation:
You have your given equation:
2a - 3b = -11
a + 3b = 8
You need to find what a and b is.
To find b:
2a - 3b = -11
-2a - 6b = -16
I multiplied a + 3b = 8 by -2. When you multiply a number you have to multiply all of them. You have to choose a number that would cancel out all of a.
So now your equation would look like this when you solve for b:
2a - 3b = -11
-2a - 6b = -16
-------------------
a - 9 = -27 then you divide -9 to -27 which is 3 so b = 3.
To find a:
2a - 3b = -11
a + 3b = 8
I multiplied a + 3b = 8 by -1 and 2a - 3b = -11 by -1 as well.
Your equation will look like this when you solve for a:
-2a + 3b = 11
-1a - 3b = -8
------------------
-3a = 3 then divide -3 to 3 which is -1 so a = -1.
Check to see if you have the correct answer by plugging in the number you got for a and b into the equation and solve.
1. 2(-1) -3(3) = -11
-2 - 9 = -11
2. -1 + 3(3) = 8
-1 + 9 = 8

What is the best way to determine whether a given point is a solution to a system of equations?
A. Substitute the x and y coordinates into one equation and check to see if they work.
B. Graph the equations and see if the point lies on both lines
C. Substitute the x and y coordinate into both equations and check to see if they work
D. Solve the system of equations and compare the answer to the given point
Substitute the x and y coordinate into both equations and check to see if they work is a best way to determine whether a given point is a solution to a system of equations.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
The best way to determine whether a given point is a solution to a system of equations is to substitute the x and y coordinate into both equations and check to see if they satisfy the equation.
And if the solutions do not satisfy the equation that means given x , y are not the solutions.
And if the unknowns are the solutions of system of the equation that
means the pair of point lies in the graph.
Therefore the answer is option C.

Given: f(x) = 1/x+5 and g(x) = x - 2.
What are the restrictiorts of the domain of f(g(x))?
0 x4 -5
O X-3
OX= 2
There are no restrictions.
Answer:
The restriction of the domain of f(g(x)) is that x cannot be 3.
Step-by-step explanation:
The first step to solve this question is finding the function, replacing the values. So
[tex]f(x) = \frac{1}{x+5}[/tex]
[tex]g(x) = x - 2[/tex]
[tex]f(g(x)) = f(x - 2) = \frac{1}{x - 2 + 5} = \frac{1}{x - 3}[/tex]
The function is a fraction, which means that the restriction is that the denominator cannot be zero. So
[tex]x - 3 \neq 0[/tex]
[tex]x \neq 3[/tex]
The restriction of the domain of f(g(x)) is that x cannot be 3.

Use the expression to answer Rewrite the expression above using two whole numbers.
what is the sign of f on the interval -5
Answer:
f(x) = x3 - 3x + 1
f'(x) = 3x2 - 3 = 3(x2 - 1) = 3(x+1)(x-1)
Find the critical numbers: set f'(x) = 0
3(x+1)(x-1) = 0 x = 1, -1
Check the sign of f'(x) on either side of each critical number. If f'(x) is positive on an interval, then f is increasing on the interval. If f'(x) is negative on an interval, then f is decreasing on the interval.

express 28x-35y=-7,inthe form ax+by+c=0and find the value of a,b,&c
Answer:
a = 28, b = -35 and c =7
Step-by-step explanation:
Given expression is :
28x-35y=-7
We need to express it in the form of ax+by+c=0 and then find the value of a,b and .
Adding 7 to both sides.
28x-35y+7=-7+7
28x-35y+7=0
or
28x+(-35y) +7=0
It is in the form of ax+by+c=0.
On comparing,
a = 28, b = -35 and c =7
Select all the intervals where f is decreasing
One Answer: Choice C) 0 < x < 1
==================================================
Explanation:
Let's go through the answer choices one at a time.
Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.Choice D is false because choice C was shown to be true.The correct option is C
What is a decreasing function?A function whose value decreases as the independent variable increases over a given range is called a decreasing function.
Considering the options :
A) it represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.
B) It is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.
In contrast, C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.
Hence, the correct option is 0 < x < 1
