Answer:
2x^2 - 7
we can plug any values of x into this The domain is All Real x.
The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7
so the range is f(x) <= -7 or (-∞, -7]

Answer:
[tex]a=2.6-3.4b[/tex]
Step-by-step explanation:
So we have the equation:
[tex]2.2a+3.4b=1.2a+2.6[/tex]
And we want to solve for a.
So, subtract 1.2a from both sides:
[tex](2.2a+3.4b)-1.2a=(1.2a+2.6)-1.2a\\1a+3.4b=2.6[/tex]
Now, subtract 3.4b from both sides:
[tex](a+3.4b)-3.4b=2.6-3.4b\\a=2.6-3.4b[/tex]
And that's our answer :)
What is the approximate side length of a game board with an area of 160 in.
Answer:
13 in
Step-by-step explanation:
[tex]\sqrt{a} =160[/tex]²
Perfect squares close to 160 include 144 and 169
12²=144
13²=169
Now that we can see 160 is closer to 169 rather than 144,
[tex]\sqrt{160}[/tex]≈ 13 in

Answer:
[tex](x-5)(x+8)=x^2+3x-40[/tex]
Step-by-step explanation:
So we have the expression:
[tex](x-5)(x+8)[/tex]
To multiply, distribute the left to the terms on the right:
[tex]=(x-5)(x)+(x-5)(8)[/tex]
Distribute:
[tex]=(x^2-5x)+(8x-40)[/tex]
Combine like terms:
[tex]=(x^2)+(-5x+8x)+(-40)[/tex]
Simplify:
[tex]=x^2+3x-40[/tex]
Therefore:
[tex](x-5)(x+8)=x^2+3x-40[/tex]
Answer:
Step-by-step explanation:

two strips of fabric measures 14 3/4 inches and 20 7/8 inches in length. to form one length, the strips are sown together using 1/2 inch from each strip to make the seam. what is the final length of the fabric after two strips are sewn together
Answer:
34 5/8 inches
Step-by-step explanation:
Let the two strips be fabric A and fabric B
Fabric A= 14 3/4 inches
Fabric B = 20 7/8 inches
To form one length, the strips are sown together using 1/2 inch
Length after sewing=
Fabric A - 1/2 inch
= 14 3/4 inches - 1/2 inch
= 59/4 - 1/2
= 59-2 /4
= 57/4 inches
Length after sewing=
Fabric B - 1/2 inch
= 20 7/8 inches - 1/2 inch
= 167/8 - 1/2
= 167-4 /8
= 163/8 inches
Final length of the fabric after two strips are sewn together
= 57/4 inches + 163/8 inches
= 114+163 /8
= 277/8
= 34 5/8 inches
Final length of the fabric after two strips are sewn together= 34 5/8 inches

Step-by-step explanation:
Simplify the following:
(-(2 + 2/3))/(-(1 + 1/3))
(-(2 + 2/3))/(-(1 + 1/3)) = (-1)/(-1)×(2 + 2/3)/(1 + 1/3) = (2 + 2/3)/(1 + 1/3):
(2 + 2/3)/(1 + 1/3)
Put 1 + 1/3 over the common denominator 3. 1 + 1/3 = 3/3 + 1/3:
(2 + 2/3)/(3/3 + 1/3)
3/3 + 1/3 = (3 + 1)/3:
(2 + 2/3)/((3 + 1)/3)
3 + 1 = 4:
(2 + 2/3)/(4/3)
Put 2 + 2/3 over the common denominator 3. 2 + 2/3 = (3×2)/3 + 2/3:
((3×2)/3 + 2/3)/(4/3)
3×2 = 6:
(6/3 + 2/3)/(4/3)
6/3 + 2/3 = (6 + 2)/3:
((6 + 2)/3)/(4/3)
6 + 2 = 8:
(8/3)/(4/3)
Multiply the numerator by the reciprocal of the denominator, (8/3)/(4/3) = 8/3×3/4:
(8×3)/(3×4)
(8×3)/(3×4) = 3/3×8/4 = 8/4:
8/4
The gcd of 8 and 4 is 4, so 8/4 = (4×2)/(4×1) = 4/4×2 = 2:

Which numbers in Set A = {−7, −4, 2, 14, 21, 34, 42} are elements of both Set B and Set C, shown below? Set B = {even numbers} Set C = {multiples of 7} and Enter answers from smallest to largest THERE ARE TWO QUESTIONS
Answer:
14, 42
Step-by-step explanation:
Set A = {−7, −4, 2, 14, 21, 34, 42}
Set B = {even numbers}
Set C = {multiples of 7}
There is only one question asked
Which numbers in Set A are elements of both Set B and Set C,
We need it to be even and a multiple of 7
14 is even and a multiple of 7 and 42 is even and a multiple of 7
Answer:
[tex]\Huge \boxed{\mathrm{\{ 14, 42\} }}[/tex]
Step-by-step explanation:
[tex]\mathrm{Set \ A = \{-7, -4, 2, 14, 21, 34, 42\} }\\\\\\\mathrm{Set \ B = \{even \ numbers\} } \\\\\\\mathrm{Set \ C = \{multiples \ of \ 7\}}[/tex]
Whatever number is in Set A, it must also be in Set B and Set C.
The elements in Set A must be an even number and a multiple of 7.
Multiples of 7 from Set A are -7, 14, 21, 42.
The even numbers from these multiples of 7 are 14 and 42.

Find the distance between the points: (-3, -4) and (5, 5). If necessary, round your answer to the nearest tenth. A.14.4 b.19 c.12 d.11.8
Answer:
The answer is option CStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-3, -4) and (5, 5)
The distance between them is
[tex]d = \sqrt{( { - 3 - 5})^{2} + ({ - 4 - 5})^{2} } \\ = \sqrt{ ({ - 8})^{2} + ( { - 9})^{2} } \\ = \sqrt{64 + 81} \\ = \sqrt{145} \\ = 12.04159 [/tex]We have the final answer as

y=-|x-2|
Please help me
Answer:
y = -|x-2| (*)
2 cases:
case 1: for x≥2 <=> |x-2| = x-2
(*) <=> y = - (x-2)
<=> y = -x+2
<=> x+y = 2
case 2: for x>2 <=> |x-2| = 2-x
(*) <=> y = -(2-x)
<=> y = x-2
<=> x-y = 2
since there are 2 variables but just one equation, we cannot find the exact values of x and y. Instead, we can find some kind of connection between them.

Step-by-step explanation:
the company started with 65 employees 12 months ago, and now there are 29. 65 - 29 = 36. In 12 months, 36 employees were laid off. 36 employees divided by 12 months = 3 employees per month.
Simplify –56 ⋅ 25 ⋅ 4. State a property that you can use.
Answer: [tex]-56\cdot 25\cdot 4 = -5600[/tex] .
Step-by-step explanation:
Associative property of multiplication : We can group numbers to multiply in any order like
[tex]p\times (q \times r) = (p\times q )\times r = p\times q\times r[/tex], where p , q and r can be any expression.
The given expression : [tex]-56\cdot 25\cdot 4[/tex]
By using associative property of multiplication, we have
[tex]-56\cdot(25\cdot 4)\\\\= -56\cdot 100\\\\=-5600[/tex]
Hence, [tex]-56\cdot 25\cdot 4 = -5600[/tex] .

A local pizza shop has a membership program for frequent buyers. The membership
costs $25 per month and members get a discounted price of $1.50 per slice of pizza.
Aaliyah purchased a membership to this pizza shop. How much would Aaliyah have
to pay the pizza shop if she bought 6 slices of pizza this month? What would be the
monthly cost for a slices of pizza?
Answer:
$34
$26.5
Step-by-step explanation:
Membership cost per month = $25
Price of a slice of pizza for members= $1.50
How much would Aaliyah have
to pay the pizza shop if she bought 6 slices of pizza this month
Total cost of Aaliyah on 6 slices of pizza = membership cost per month + prices of 6 discounted pizza
= $25 + $1.50(6)
= $25 + $9
= $34
What would be the
monthly cost for a slices of pizza
Monthly cost of Aaliyah a slices of pizza = membership cost per month + price of 1 discounted pizza
= $25 + $1.5
= $26.5
Answer:
Monthly cost for 6 slices: 25+1.50(6)=34
Monthly cost for x slices: 25+1.50x

AC = 23. AB = 2x + 2, and BC = 3x + 6. Find BC
Answer:
21Step-by-step explanation:
Given AC = 23, AB = 2x + 2 and BC = 3x+6 then using vector notation;
BA+AC = BC
Since BA = -AB
The equation becomes -AB+AC = BC
Substituting the given equations;
-(2x+2)+23 = 3x+6
open the parenthesis
-2x-2+23 = 3x+6
-2x+21 = 3x+6
collect the like terms
-2x-3x = 6 - 21
-5x = -15
Divide both sides by -5
-5x/-5 = -15/-5
x = 3
TO get BC, we will substitute x = 3 into the expression BC = 3x+6
BC = 3(5)+6
BC = 15+6
BC = 21
Hence the length of BC is 21 units
