Slope=2/4 or 1/2
Y-Intercept=8
The slope of the graph of the equation -2x + 4y = 8 is [tex]\frac{1}{2}[/tex] , and the
y-intercept is 2.
To calculate the y-intercept and slope of the graph of the equation -2x + 4y = 8, to change the given equation in the general form of line. The general form of the line is y = mx + b, where m is the slope of the line and b is the y-intercept of the line.
Find the value of y from the given equation of graph.
Calculate y as:
[tex]-2x + 4y = 8\\4y = 2x + 8\\y=\dfrac{2}{4}x+2\\ y=\dfrac{1}{2}x +2[/tex]
Here, the slop of the graph m is [tex]\dfrac{1}{2}[/tex] and y-intercept is 2
Therefore, the slope of the graph is 1/2, and the y-intercept is 2.

-8x+5y=43
-8x+4y=36
Answer:
[tex]x=-1\\y=7[/tex]
Step-by-step explanation:
Given equations:
[tex]-8x+5y=43[/tex] Equation:1
[tex]-8x+4y=36[/tex] Equation:2
As the coefficients of 'x' are same which will eliminate the terms of 'x':
Subtracting Equation:2 From Equation:1
[tex]-8x+5y-(-8x+4y)=43-36\\\\-8x+5y+8x-4y=7\\\\5y-4y=7\\\\y=7[/tex]
Putting value of 'y' in either equation:1 or 2
Putting y=7 in equation:2
[tex]-8x+4y=36[/tex]
[tex]-8x+4(7)=36\\\\-8x+28=36[/tex]
Subtracting '28' from both side:

38/312.6 or 12 remainder 2Today everything in a store is for sale. THe store offers a 30% discount. The regualar price for a T-shirt is 18$. What is the discount price
Answer:
12.60
Step-by-step explanation:
Start off by the total which is 18. To find the percentage off you will have to make the 30% into a decimal, so simply move it two spaces to the left. Now you have .30. Multiply the decimal, .30, and the full amount, 18. Your equation now should be (.30)*(18). Your answer will be 5.40. 5.40 is what is off of the shirt from the original price, so subtract 5.40 from 18. Your equation now is (18-5.40) which is 12.60.
In the above figure, m∠AOC = 26° and m∠BOD = 2x + 32. If ∠AOC and ∠BOD are vertical angles, what is the value of x?
The value of x is -3.
Step-by-step explanation:
It is given that the angles ∠AOC and ∠BOD are vertical angles.The vertical angles have same measure of angles.Therefore, ∠AOC is equal to ∠BOD.⇒ 26° = 2x+32
⇒ 2x = 26-32
⇒ 2x = -6
⇒ x = -6/2
⇒ x = -3
Substitute x=-3 in ∠BOD = 2x+32
∠BOD = 2(-3)+32 = 26°

A cylindrical water tank has a radius of 5 feet and a height of 10 feet. The volume of water in the tank is 565.2 cubic feet.
What percent of the tanks volume is filled with water?
About 71.96% of the cylindrical water tank, with a radius of 5 feet and a height of 10 feet, is filled with water when it contains 565.2 cubic feet of water.
To determine what percent of the tank's volume is filled with water, we must first calculate the total volume of the cylindrical tank using the formula for the volume of a cylinder: V = (pi)r²h. Here, the radius r is 5 feet, and the height h is 10 feet.
The total volume V of the tank is:
V = (pi)(5 feet)²(10 feet) = 3.14159 times 25 times 10 = 785.398 cubic feet
Now, since the volume of water in the tank is given as 565.2 cubic feet, we can calculate the percent of the tank's volume that is filled with water by dividing the volume of water by the total volume of the tank and then multiplying by 100 to convert to a percentage. So the calculation becomes:
Percent filled = ([tex]\frac{565.2}{785.398}[/tex]) times 100
Percent filled approx 71.96%
Therefore, about 71.96% of the tank's volume is filled with water.

What is the y-intercept (b value) of a line that is PERPENDICULAR to the line y = -x- 2and through
the point (-3,-7)
Answer:
The y -intercept is the point (0, -4).
Step-by-step explanation:
The slope of the perpendicular line = -1/m
= -1/-1 = 1.
So it is y = x + b.
To find b we substitute the point (-3, -7):
-7 = -3 + b
b = -7 + 3 = -4.
The y -intercept is the point (0, -4).

Find a(33) if the first term in the sequence is 3 and the common difference is -1.
Answer:
Step-by-step explanation:
a(n) = a + (n-1)d
a(33) = 3 + (33-1)*(-1)
= 3 + 32*(-1)
= 3 - 32
= -29
The 33rd term (a33) in an arithmetic sequence starting with 3 and a common difference of -1 is -29. This is achieved by using the formula for finding a term in an arithmetic sequence.
Explanation:The question is asking for the 33rd term in a sequence where the first term is 3 and each following term is derived by subtracting 1 from the previous term, a common process known as an arithmetic sequence. The formula to find any term (an) in an arithmetic sequence is an = a1 + (n - 1)d, where a1 is the first term, d is the common difference, and n is the term number.
So, to find a(33) (the 33rd term), we will fill in the formula as follows: a33 = 3 + (33 - 1)*-1
Which simplifies to: a33 = 3 - 32 = -29
So the 33rd term of the sequence is -29.

Natasha paid $4 per paintbrush
Natasha paid $17.50 per paintbrush
Natasha paid $6 per paintbrush
Natasha paid $21 per paintbrush
Answer:
Step-by-step explanation:
Cost of paint brushes= Total cost - cost of paint
= 71 - 50 = $21
No.ofpaint brushes =21/3.50 = 21*10/3.5*10
= 210/35 = 6
Answer:
Natasha paid $6 per paintbrush
Step-by-step explanation:
Cost for paint brusheswe can make use of variables
p = paint
b = brushes
bought paintbrushes and paint for a total of $71. . The brushes cost $3.50 per brush and the paint cost $50
we can create an equation from the information
3.5b + 50p = 71
since 1 paint is bought
3.5 b + 50 (1) = 71
3.5b = 71 - 50
3.5b = 21
b = 21/3.5
b = 6
paintbrush costs $ 6An angle measures 65.6° less than the measure of its complementary angle. What is the
measure of each angle? This is IXL w17 7th grade. Thanks!
Answer:
The 2 angles are 12.2 and 77.8 degrees.
Step-by-step explanation:
Let the measure of one angle be x degrees, then it's complementary angle = 90-x degrees.
So we have the equation:
x = 90 - x - 65.6
2x = 90 - 65.6 = 24.4
x = 12.2 degrees.
Its complement = 90 - 12.2 = 77.8 degrees.

z varies directly as x². If z=8 when x=2, find z when x=7
Answer:
98
Step-by-step explaination:
For this question, it is a direct variation. Hence, the equation would be formed accordingly, and the constant k would also be used.
z varies directly as x²
z= kx² where k is the constant
z = 8
x = 2
Putting the figures in the equation, we have
8=2²(k)
8= 4k
Dividing both sides by 4, we have
k = 8/4
k = 2
Solving for z now, we substitute k with 2. And x with 7
z=kx²
z = 2(7²)
z= 2(49)
z= 98
If it were indirect variation, the constant would have been 1/k. We also have other types of variation, Indirect variation, partial variation and joint variation.
Cameron wants to buy six video games all costing the same amount he has a $30 coupon and he can spend no more than $100 write an inequality to find the possible cost of each video game
Let's work this problem step by step, using each piece of given information to create the inequality:
Let x represent the cost of each video game that Cameron wants to buy. The price of the 6 games will be 6 multiplied with x, or 6x.Cameron has a $30 coupon, which means that the price of the video games after the coupon will be 30 less than 6x, which is 6x - 30.The last piece of information is that Cameron cannot spend any more than $100. Thus, the equation 6x - 30 must be less than or equal to 100.Putting all this together, we can create the inequality:
[tex]6x-30\leq 100[/tex]
If you need the inequality solved for x, let me know and I'll help you solve it

A cylindrical pipe has a circumference of 16cm
Calculate the diameter of the pipe
Please show method cleary
Step-by-step explanation:
pi×diamiter = circumference
pi÷circumference = diamiter
3.14159265358979 (pi) ÷ 16
Calculate the diameter of a cylindrical pipe with a circumference of 16cm using the formula C = πd. Hence the diameter of the pipe is approximately 5.09 cm.
The circumference of a cylindrical pipe is related to its diameter through the formula C = πd, where C is the circumference, π is Pi (approximately 3.14159), and d is the diameter. Given that the circumference is 16 cm, we can use the formula to solve for the diameter:
16 = πd
16 = 3.14159d
d = 16 / 3.14159 ≈ 5.09 cm
Therefore, the diameter of the pipe is approximately 5.09 cm.
