Answer:
x-12≤7
x≤19
Step-by-step explanation:
less than means it comes after
x-12
is at most means less than or equal to
x-12≤7
Add 12 to each side
x-12+12≤7+12
x≤19
Answer:
X - 12 ≤ 7; X ≤ 19
Step-by-step explanation:
Using the keywords less than, at most, and 'a number' we can identify the expression.
Now let's solve for x:
x - 12 ≤ 7
+12 +12
X ≤ 19

Nicky wants to surround a 25 in. by 16 in. painting with a frame that is w inches wide. Which quadratic function represents the combined area A of the picture and the frame?
A. A(w) = 4w2 + 32w + 400
B. A(w) = 4w2 + 42w + 400
C. A(w) = 4w2 + 64w + 400
D. A(w) = 4w2 + 82w + 400
Answers
Answer:
Option "D" is the correct answer to the following question.
Step-by-step explanation:
Given:
Length of painting = 25 inch
Height of painting = 16 inch
Width of frame = w inch
Find:
Area of Picture with frame
Computation:
New length of painting = 25 + w + w
New length of painting = 25 + 2w inch
New height of painting = 16 + w + w
New height of painting = 16 + 2w
Area = l x b
So,
Area of Picture with frame = [25 + 2w][16 + 2w]
Area of Picture with frame = 400 + 50w + 32w + 4w²
Area of Picture with frame = 4w² + 82w + 400
Find the length to the third side. If necessary, round to the nearest tenth.

Grammy is buying a pair of Jeans that regularly cost $40. They are on sale for 20% off.
If the tax rate is 8%, what is the sale price of the Jeans Including tax?
Answers
Answer:
$34.56
Step-by-step explanation:
First, find the discount price.
20% of 40
20/100 x 40= $8
Deduct the discount from the original price.
40 - 8 = $32
This is the discount price.
Now, find 8% (tax) of the price.
8/100 x 32 = $2.56
Add it to the price.
32 + 2.56 = $34.56

A refrigerator is sold for $1998 and a 11% profit is made.
Find the original cost of that refrigerator.
Answers
Answer:
Cost Price = $1800
Step-by-step explanation:
Let cost price (CP) be x
Selling price(SP) = 1998
Profit = Selling price - cost price = 1998 - x
[tex]profit \% = \frac{SP - CP}{CP}[/tex]
[tex]\frac{11}{100} = \frac{1998-x}{x}[/tex]
[tex]0.11 = \frac{1998}{x} - 1\\\\1 + 0.11 = \frac{1988}{x}\\\\1.11 = \frac{1998}{x}\\\\x = \frac{1998}{1.11} = 1800[/tex]

Write a function in any form that would match the graph shown below.
Answers
Answer:
y + 16 = -1(x + 3)²
Step-by-step explanation:
Looking at the graph, parabola vertex opens upwards with x intercepts as -5 and -1.
Thus, the line of symmetry will be;
x = (-5 + (-1))/2 = -3
Looking at the graph we can see that the vertex when traced to the x - coordinate will be 3 which is same with what we got.
Now, the general form of the equation will be;
y - h = a(x - k)²
where (k,h) is the vertex coordinate
Thus, k = -3
So;
y - h = a(x - (-3))²
>> y - h = a(x² + 6x + 9) =
>> y = ax² + 6ax + 9a + h
When, x = 0
y = 9a + h
From the graph, we can see that the y-intercept is y = -25
Thus;
9a + h = -25
From the graph, h which is the y-coordinate of the vertex = -16
Thus;
9a - 16 = - 25
9a = -25 + 16
9a = -9
a = -9/9
a = -1
Thus, the equation is;
y - (-16) = -1(x - (-3))²
>> y + 16 = -1(x + 3)²
The size of angle DEF
Answers
Answer
132 degrees
Step-by-step explanation:
Strategy: Find angle DEB and using that fact that DEB + DEF is 180 degrees to find angle DEF
The sum of the four angles of any quadrilateral is 360 degrees.
Since three angles are given, we can use that to find the fourth.
360-(147+93+72)=size of angle DEB. Solving, you get angle DEB is 48.
Also, knowing that segment BF is a straight line, it means that angle DEB + angle DEF is equal to a straight angle (180 degrees).
DEB+DEF=180
48+DEF=180
DEF=180-48=132 degrees.
Thus, angle DEF is equal to 132 degrees.

Write x as a logarithm in the following: 10^x=7
Answers
Answer:
x = log 7
Step-by-step explanation:
10^x=7
Take the log base 10 on each side
log10 (10^x)=log10 (7)
We dont need to write the 10, it is implied
log(10^x)=log (7)
The exponent goes out front since log a^b = b log a
x log 10 = log 7
log 10 = 1 since the base is 10 log10(10) =1
x = log 7
