what is the answer to this? −1.2b−5.3≥1.9
Answers
Answer:
b≤−6
here u go
Answer:
b ≤ -6 ✅Step-by-step explanation:
To solve an inequality, we will solve just like a normal equation. The goal is to isolate b, so we can determine the set of values it can take on.
Step 1: Add 5.3We need to reverse the operation - 5.3, so we add 5.3.
-1.2b - 5.3 + 5.3 ≥ 1.9 + 5.3
-1.2b ≥ 7.2
Step 2: Divide by -1.2We need to reverse the multiplication that is multiplying b by -1.2, so we will divide. However, we must remember an important rule first.
Important: When we divide by a negative number in an inequality, we must reverse the inequality sign, so ≥ becomes ≤.
-1.2b / -1.2 ≥ 7.2 / -1.2
b ≤ -6 (remember to reverse the sign!)
Step 3: CheckWe now substitute our answer in and see if it is correct. We will use a number that is smaller than -6, for example, -8.
-1.2(-8) - 5.3 ≥ 1.9
9.6 - 5.3 ≥ 1.9
4.3 ≥ 1.9 ✅
We can check again with -6, since this and all numbers smaller than it should be a solution set.
-1.2(-6) - 5.3 ≥ 1.9
7.2 - 5.3 ≥ 1.9
1.9 ≥ 1.9 ✅

Answer:
C
Step-by-step explanation:
The zeros are also known as x-intercepts so it is the points on the x axis.
For x-intercepts the y is 0 so it is (-1,0) and (5,0)

What is the correct factorization of:
x? - 11x + 18
Answers
9514 1404 393
Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)

Answer:
- 1/4
Step-by-step explanation:
The formula to find slope from two points is (x₂ - x₁) / (y₂ - y₁).
Substituting the points in (2, 4 = x₁, y₁ and 5, -8 = x₂, y₂) we get (5 - 2) / (-8 - 4).
= 3 / -12
= - 1/4
(Tip: when assigning the numbers to the variables, make sure x₁, y₁ are always from the same pair.)

Step-by-step explanation:
Step 1: Substitute -x+18 for y in y=8x:
-x+18=8x Add X to both sides
9x=18 Divide 9 by both sides
x=2
y=8(2)Plug in the new value for x(which is 2) into one of the equations

There are 12 applicants for financial aid. The Scholarship allows four students to receive the money. How many different ways can these scholarships be awarded? The first scholarship is $1000, the second is $750, the third is $500, and the last is $250. Only place a numeric value as an answer.
Answers
Answer:
495 ways
Step-by-step explanation:
Given that:
Total number of applicants (n) = 12
Required number (r) = 4
Using the combination formula :
nCr = n! / (n-r)!r!
12C4 = 12! / (12 - 4)!4!
12C4 = 12! / 8!4!
12C4 = (12*11*10*9) / 4*3*2*1
12C4 = 11880 / 24
= 495 ways

You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798
Answers
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
