Step-by-step explanation:
a)1) As denominators are same, keep the same denominator for the result also
Add the numerators and write the new numerator.
[tex]\frac{3y}{4}+\frac{5y}{4}=\frac{3y+5y}{4}=\frac{8y}{4}[/tex] = 2y

3) Maurice has a pet hamster. In October he spent
$ 13.68 on hamster food
$ 7.89 on wood shavings
$ 21.14 on a new hamster wheel.
About how much money did he spend on his hamster? Estimate by rounding each amount to
the nearest dollar.
Exactly how much did he spend on his hamster in October?
Answer:
now
Step-by-step explanation:
The amount of money that he spent on his hamster round to the nearest dollar will be $43.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Maurice has a pet hamster. In October he burned through $13.68 on hamster food $7.89 on wood shavings and $21.14 on another hamster wheel.
Then the amount of money that he spent on his hamster will be given by the summation of $13.68, $7.89, and $21.14.
⇒ $13.68 + $7.89 + $21.14
⇒ $42.71
⇒ $43
The amount of money that he spent on his hamster round to the nearest dollar will be $43.

Determine which of the following relationships is true.
O DE=2AC
Om BCA = 2(m_BED)
O DE = AC
DEI|AC
Answer:
DE is parallel to AC
DE = 2AC
ExplanationIn triangle ABC, BD = AD
BE = EC
D is mid point of AB
E is the mid point of AC
According to the mid point theorem, ( The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”) DE is parallel to AC and equal to half of it
Answer:
For clarification, the answer is DE||AC or in other words, DE is parallel to AC.

A 35-foot tall pole is leading towards a building. To stop the pole from leaning further, a 48-foot long cable is secured from the top of the pole to a stake in the ground opposite of the building. If the stake is 30 feet from the pole, what angle does the cable make with the pole?
Round the answer to the nearest tenth.
9514 1404 393
Answer:
38.5°
Step-by-step explanation:
A triangle solver can give an answer easily. The angle is 38.5°.
__
The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.
C = arccos((a² +b² -c²)/(2ab))
Here, we have a=35, b=48, c=30, so the angle is ...
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°
The angle the cable makes with the pole is about 38.5°.

Answer: Good luck guys
a) 4(9 x - 18) > 3(8x + 12)
The solution to the inequality is x > 9.
Graph A.
b) -1/3 (12x + 6) ≥ -2x + 14
The solution to the inequality is x ≥ -8.
Graph B.
c) 1.6 (x + 8) ≥ 36.4
The solution to the inequality is x ≥ 14.75.
Graph C.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
a)
4(9x - 18) > 3(8x + 12)
First, we can simplify both sides of the inequality:
36x - 72 > 24x + 36
Next, we can isolate the variable on one side by subtracting 24x from both sides:
12x - 72 > 36
Finally, we can isolate x by adding 72 to both sides:
12x > 108
x > 9
Therefore, the solution to the inequality is x > 9.
b)
-1/3(12x + 6) ≥ -2x + 14
First, we can simplify the left-hand side of the inequality:
-4x - 2 ≥ -2x + 14
Next, we can isolate the variable on one side by adding 4x to both sides:
-2 ≥ 2x + 14
Then, we can isolate x by subtracting 14 from both sides:
-16 ≥ 2x
Finally, we can divide both sides by 2, remembering to reverse the direction of the inequality because we are dividing by a negative number:
-8 ≤ x
Therefore, the solution to the inequality is x ≥ -8.
c)
1.6(x + 8) ≥ 36.4
First, we can simplify the left-hand side of the inequality:
1.6x + 12.8 ≥ 36.4
Next, we can isolate the variable on one side by subtracting 12.8 from both sides:
1.6x ≥ 23.6
Finally, we can divide both sides by 1.6:
x ≥ 14.75
Therefore, the solution to the inequality is x ≥ 14.75.
Thus,
a) 4(9 x - 18) > 3(8x + 12)
The solution to the inequality is x > 9.
Graph A.
b) -1/3 (12x + 6) ≥ -2x + 14
The solution to the inequality is x ≥ -8.
Graph B.
c) 1.6 (x + 8) ≥ 36.4
The solution to the inequality is x ≥ 14.75.
Graph C.

Subtract the sum of −7 and 13 from the sum of −2 and −9 *
Answer:
-17
Step-by-step explanation:
The sum of -2 and -9 is (-2) + (-9) = -2 - 9 = -11.
The sum of -7 and 13 is 13 - 7 = 6.
Hence, subtracting 6 from -11 would be -11 - 6 = -17.

If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.
x + 1 + 6x + 6 + 8
7x + 15 is your final answer.
However, I think the question is

Let y = x + 1
y^2 + 6y + 8
(y + 2)(y + 4)
(x + 1 + 2 ) ( x + 1 + 4)

B.
The y-intercept is , and the slope is .
C.
The y-intercept is , and the slope is .
D.
The y-intercept is , and the slope is .
Answer:
the y-intercept is 8 and the slope is -4/3 .
Step-by-step explanation:
The y - intercept is (0, 8) and the slope is -4/3
What is the y-intercept?"It is the point at which the graph of the function intersects the y-axis"
What is slope?The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
For given example,
We can observe that the line of best fit on this scatter plot passes though points (0, 8) and (6, 0)
Using the slope formula,
⇒ slope = (0 - 8)/(6 - 0)
⇒ slope = (-8)/6
⇒ slope = -4/3
Also, we can observe that the line of best fit on this scatter plot intersects y-axis at point (0, 8)
So, the y - intercept is (0, 8)
Therefore, the y - intercept is (0, 8) and the slope is -4/3

A sports store is having a 20% off sale on skis. The original price of the ski is $560.00
The tax rate is 8.5%. What is the total cost of the skis?
Answer:
Total cost: 486.080$
Step-by-step explanation:
Original Price: 560.000$
Sale: 20%
Discount: 560.000$ * 20% = 112.000$
Discounted Price: 560.000$ - 112.000$ = 448.000$
Tax Rate: 8.5%
Tax: 448.000$ * 8.5% = 38.080$
