The value of expression at x = 3 is,
⇒ 30
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 6² + x - x²
Now, We can simplify as;
⇒ 6² + x - x²
⇒ 36 + x - x²
Put x = 3;
⇒ 36 + 3 - 3²
⇒ 36 + 3 - 9
⇒ 36 - 6
⇒ 30
Thus, The value of expression at x = 3 is,
⇒ 30

Answer:
The answer is
[tex]y = 3x + 5[/tex]
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ↶
[tex]y = mx + b[/tex]
❃Since we already have the slope, we don't need to solve for that.
➊ First: We are going to find the y-intercept.
[tex]y = mx + b \\ 2 = 3( - 1) + b \\ 2 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: }{5 = b}[/tex]
➋Second: Plug in.
[tex]y = 3x + 5[/tex]
Which of the following is logically equivalent to “I wear a jacket if it is cold outside." ?
If I wear a jacket, then it is cold outside.
If I do not wear a jacket, then it is not cold outside.
I wear a jacket if and only if it is cold outside.
If it is not cold outside, then I do not wear a jacket.
The option from the following that is logically equivalent to the statement is that: If it is not cold outside, then I do not wear a jacket.
What is Logical equivalence?Two statements are regarded to be logically equivalent if, and only if, their resultant forms are logically equivalent during the time at which identical statement variables are utilized to illustrate their component statements.
Similarly; two statement forms are noted to be logically equivalent if, and only if, their resultant truth tables show an identical form per variation of statement variables.Therefore, we can conclude that the correct option that is logically equivalent to the statement being made is that: If it is not cold outside, then I do not wear a jacket.

Which expressions are equivalent to x/3x times 8x/3x? Select all that apply?
a. 8x^2/9x^2
b. 8x^2/3x
c. 8x/3, for x not equal to 0
d. 8/9, for x not equal to 0
e. 9x^2/9x^2
f. 1, for x not equal to 0
Answer:
A, D
Step-by-step explanation:
x/3x times 8x/3x is equivalent to x(8x)/[(3x)(3x)] i.e. 8x^2/9x^2 or 8/9.
A is correct obviously.
B is not correct since the coefficients and degrees are different.
C is not correct since the coefficients and degrees are different.
D is correct.
E is obviously wrong by comparing the coefficients.
F is also wrong since 8/9 is not equal to 1.
So the correct answers are A and D.
The expressions equivalent to (x/3x) * (8x/3x) is 8/9 and 8x² / 9x²
An equation is an expression that is used to show the relationship between two or more variables and numbers.
Given the equation:
(x/3x) * (8x/3x)
Multiplying the numerator and denominator:
= (x * 8x)/(3x * 3x)
= 8x² / 9x²
Further simplifying the equation:
= 8/9
The expressions equivalent to (x/3x) * (8x/3x) is 8/9 and 8x² / 9x²

Start by finding the scale of this map. At the actual gym, one side length of the snack stand is 60 feet. On the scale map, it is 20 cm. What is the scale?
Answer:
I actual foot represents 0.01093 foot on paper
Step-by-step explanation:
Given that :
Actual side length of snack stand = 60 feets
Length of side on map = 20cm
Scaie :
60 feet = 20cm
1 foot = (20/60) cm
1 foot = 0.333 cm
1cm = 0.0328084 foot
0.333cm = (0.33 * 0.0328084) = 0.01093 feets
Scale :
I actual foot represents 0.01093 foot on paper
Which expressions are equivalent to
?
1/5x1/5x1/5x1/5
Choose 2 answers:
Answer:
we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]
Hence, options A and D are true.
Step-by-step explanation:
Given the expression
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}=\frac{1\cdot \:\:1\cdot \:\:1\cdot \:\:1}{5\cdot \:\:5\cdot \:\:5\cdot \:\:5}[/tex]
[tex]=\frac{1}{5\cdot \:5\cdot \:5\cdot \:5}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Checking options B and C:
Option B
[tex]\left(5^{-4}\right)^0=1[/tex]
Option C
[tex]\frac{5^1}{5^4}=\frac{5}{625}=\frac{1}{125}[/tex]
Thus, options B and C are not equivalent!
Checking Option A
Option A
[tex]\left(5^{-2}\right)^2[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(5^{-2}\right)^2=5^{-2\cdot \:2}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Now, checking option D
Option D
[tex]5^2\cdot \:5^{-6}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
[tex]5^2\cdot 5^{-6}=5^{2-6}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Therefore, we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]
Hence, options A and D are true.
On a sunny day, Larry notices that his shadow is 24 inches long. If it is 74 inches from the top of his head to the end of the shadow, how tall is Larry?
Answer:
70 inches
Step-by-step explanation:
Larry forms a right triangle with the ground (this is one leg of a right triangle) and he is 24 inches from his shadow (this is the second leg).
74 inches is the hypotenuse of the right triangle
use pythagorean theorem: a^2 + b^2 = c^2
let h = Larry's height
h^2 + 24^2 = 74^2
h^2 + 576 = 5476
h^2 = 4900
h = sq rt 4900
h = 70
A group of friends wants to go to the amusement park. They have no more than $275
to spend on parking and admission. Parking is $5, and tickets cost $27 per person,
including tax. Write and solve an inequality which can be used to determine 2, the
number of people who can go to the amusement park.
Answer:
10 persons
Step-by-step explanation:
Step one:
given data
We are told that they have a total of $275
also, they want to spend $5 on packing space
and a ticket cost $27 per person.
Step two:
let the number of persons be x
and let the total amount to be spent be y
hence the inequality is
y≤ 5+ 27x
now for y= $275, let us find x
Substitute into the inequality we have
275≤5+27x
275-5≤27x
270≤27x
Divide both sides by 27
x ≤ 270/27
x ≤ 10
Hence the number of persons should not be more than 10
Answer:
Inequality: 25x+10_<275
Answer: x_<10.6

Answer:
g(x) is shifted 3 to the left and 5 up
Step-by-step explanation:
I am very horrible at explaining these things, especially why it's 3 to the left and not to the right, but you'll have to trust me on that one.
As far as the 5 up part, you take the function (x+3)^2 and you always add 5, raising every output by 5.

For a fundraiser, a group plans to sell granola bars and bottles of water at the same prices as described in Part A. The group wants the income from the fundraiser to be at least $150. Choose the inequality to show the number of granola bars x and the number of bottles of water y that must be sold.
Incomplete question. The missing part read;
Ten granola bars and twelve bottles of water cost $23. Five granola bars and four bottles of water cost $10.
Options:
A. 1.4x + 0.75y > 150
B. 1.4x + 0.75y ≥ 150
C. 1.4x + 0.75 < 150
D. 1.4x + 0.75 ≤ 150
Answer:
B. 1.4x + 0.75y ≥ 150
Step-by-step explanation:
Remember, from the question we are told that the group wants the income from the fundraiser to be at least $150, meaning, they are not against having an income above $150 from the fundraiser, but a minimum of at least that amount.
Hence, among all the listed options, the correct inequality sign to represent the number of granola bars 'x' and the number of bottles of water 'y' that must be sold is the ≥ (equal to or greater than sign).
