Answer:
8y + 6x
Step-by-step explanation:
Combine like terms
y + 3x +4y + x + 3y + 2x
= (y + 4y + 3y) + ( 3x + x + 2x)
= 8y + 6x
A man's age is three times his son's age. Ten years ago, he was five times his son's
age. By forming two equations and solving them simultaneously, find both of their ages.

Anyone helps me pleaseeeeee✨
I will so so so love you if you help me to solve it!!!!!!!!!
Answer: Hope it helps :)
Step-by-step explanation:
The essential thing to learn from this lesson is the translation of equations. When f(x) = f'(x) + a, the graph of the equation is shifted up by a units.
When f(x) = f'(x + a), the graph of the equation is shifted left by a units.

Answer: 6.45 x 10^10
Step-by-step explanation:
Because 10^5 and 10^4 both have 10, we can add the exponents to get 10^9.
Multiplying 7.5 and 8.6 gets you
7.5 * 8.6 = 64.5
We can move the decimal up a place to get 6.45 and add another power to 10^9 to get 10^10
Your final answer should be 6.45 x 10^10
Answer:
C 6.45x 10 to the power of 10
Step-by-step explanation:
10 to the power of 5 is 100,000. 7.5x100,000 is 750,000.
10 to the power of 4 is 10,000.
10,000x8.6 is 86k
now we do 750,000x86,000 which is 64,500,000,000
10 to the power of 10 is 10 billion times 6.45 is 64,500,000,000
Mr. Chaplin measured his son’s rectangular bedrooms for new carpeting. Whose bedroom has the greatest area?
George’s bedroom 3.5 meters by 4.4 meters
Steven’s bedroom 3.8 meters by 3.8 meters
Andy’s bedroom 3.6 meters by 4.1 meters
Answer:
Step-by-step explanation: multiply each and then you choose which one is greater
which is George’s bedroom 15.4
The area of George's bedroom is the greatest with 15.4 sq meters.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the area of a rectangle is (length×width).
George’s bedroom 3.5 meters by 4.4 meters,
∴ The area of George's bedroom is (3.5×4.4) sq meters.
= 15.4 sq meters.
Steven’s bedroom 3.8 meters by 3.8 meters,
∴ The area of Steven's bedroom is (3.8×3.8) sq meters.
= 14.44 sq meters.
Andy’s bedroom 3.6 meters by 4.1 meters.
∴ The area of Andy's bedroom is (3.6×4.1) sq meters.
= 14.76 sq meters.
So, the area of George's bedroom is the greatest.

The equation 12x² + 4kx + 3 = 0 has real and equal roots, if
Answer:
[tex]k=\pm3[/tex]
Step-by-step explanation:
[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant [tex]\Delta = b^2-4ac[/tex] (or, if b is an even number, 1/4 of it) is zero.
I see it! I see it!
Stare at it for a while. First term is [tex]3(2x)^2[/tex], third term is [tex]3(1)^2[/tex], we are missing a double product, but we can play with k. For the LHS to be [tex]3(2x\pm1)^2 = 3(4x^2\pm4x+1) = 12x^2\pm12x+3[/tex] you just need [tex]4k= \pm12 \rightarrow k=\pm3[/tex].
I don't see it...
Then number crunching it is. Set the discriminant to 0, solve for k
[tex]\frac{\Delta}4 = 4k^2-12\cdot 3 =0 \rightarrow 4k^2=36 \\k^2 = 9 \rightarrow k=\pm3[/tex]
Tim earns spending money by doing odd jobs for his neighbors. The table shows how much he is paid
for each job. Tim gets $12 for mowing lawn, $9 for washing cars, and $7 for walking dogs. Tim owes his mother $23. What possible combination of jobs could Tim perform to earn
enough money to pay back his mother? Write an addition equation using integers to represent the
situation. Will he have money left over? Select the correct choice below and fill in the answer boxes to complete your choice.
Answer:
D
Step-by-step explanation:
D is the only option where Tim has 23 or more dollars earned.
To show this I will solve each equation...
A) (-23)+9+9 = (-23)+18= -5
-5 < 0 so A doesn't work
B) (-23)+7+7+7 = (-23)+21= -2
-2 < 0 so B doesn't work
C) (-23)+12+9 = (-23)+21= -2
-2 < 0 so B doesn't work
D) (-23)+12+12 = (-23)+24= 1
1 > 0 so D does work!
* I am using 0 to compare each number with the result because Tim should have 0 or more dollars after paying his mom.

Mrs. Collado is buying a
refrigerator that sells for $590.
After a 10% discount is taken,
6% sales tax is added to the
price. A $50 delivery charge is
added on after the tax is computed. What will be the final cost of the refrigerator?
9514 1404 393
Answer:
$612.86
Step-by-step explanation:
The discount multiplies the price by (1 -10%) = 0.90.
The tax multiplies the price by (1 +6%) = 1.06
Then the total price with delivery charge is ...
$590×0.90×1.06 +50 = $612.86
Answer:
612.86
Step-by-step explanation:
10% is 59 590-59=531

Transform y = cot(x) to get the graph of. Which type of transformation is not performed? vertical shift horizontal shift vertical stretch horizontal stretch.
Transformation involves changing the form of the function
The transformation that is not performed is (a) vertical shift
The function is given as:
[tex]\mathbf{y = cot(x)}[/tex]
From the complete question, the transformed function is:
[tex]\mathbf{y=3cot[\frac 15(x+2)]}[/tex]
On y = cot(x); start by translating the function 2 units left.
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (x +2,y)}[/tex]
So, we have:
[tex]\mathbf{y = cot(x + 2)}[/tex]
Next, stretch the function horizontally by a factor of 1/5
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (\frac 15x,y)}[/tex]
So, we have:
[tex]\mathbf{y=cot[\frac 15(x+2)]}[/tex]
Lastly, stretch the function vertically by a factor of 3
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (x,3y)}[/tex]
So, we have:
[tex]\mathbf{y=3cot[\frac 15(x+2)]}[/tex]
From the above transformations, we have:
Horizontal shift Vertical stretch Horizontal stretchHence, the transformation that is not performed is (a) vertical shift

What does x equal in the equation 10= 0.0048(x - 50)^2 + 6?
Answer:
x=\frac{0.48+\sqrt{0.0768}}{0.0096},\:x=\frac{0.48-\sqrt{0.0768}}{0.0096}
Step-by-step explanation:
(x-50)^2 is x^2+2500-100x*.0048 is .0048x. 2500*0.0048 is 12, and -100*0.0048=-.48.
So, we have .0048x^2+12-.48x+6, which is
.0048x^2+18-.48x=10. USing the quadratic formula, we get
x=\frac{0.48+\sqrt{0.0768}}{0.0096},\:x=\frac{0.48-\sqrt{0.0768}}{0.0096}

Answer:
Slope is 4.
y=4x + 1
Take coordinates (0,1) & (1,5)
Rise/Run
5-1/1-0 = 4
Use the table to calculate the slope and y-intercept, then write the equation in slope intercept form.
Answer: y = (28/4)x + 4
Step-by-step explanation:
We'll be using 20, 144 (1) and 24, 172 (2) for this
slope = y2 - y1 / x2 - x1
slope = 172 - 144 / 24 - 20
slope = 28/4
y = mx + b
y = (28/4)x + b
We can then reduce 20, 144 by 4, 28
20, 144
16, 116
12, 88
8, 60
4, 32
0, 4
The y-intercept is when x = 0, so its 4.
Plug that into y = mx + b
y = (28/4)x + 4
