what is the y-intercept of 10x + 5y = 30
Answer: 6
Step-by-step explanation: The y-intercept is 6 and the slope is -2.
First, we subtract 10x.
5y = -10x+30
Then we divide by 5.
y = -2x + 6
Now we have everything we need!
So the y-intercept is 6.
Hope this helps! :)
The y-intercept is "6".
Intercept:Given:
[tex]10x+5y=30[/tex]

What algebraic property is demonstrated in the equation below? 6 + 4(7x – 2) = 6 + 28x – 8
Answer:
Distributive property
Answer:
The distributive property
Step-by-step explanation:
In the equation, we can see that the 4 in 4(7x - 2) was distributed to the parentheses in the other side of the equation.
The 4 was multiplied to both 7x and -2, creating 28x - 8 on the other side of the equation.
So, this represents the distributive property.

At Maria's Beading Boutique, 15% of the 40 beads on clearance are plastic. How many plastic beads are there on clearance?
for brainliest u got to get it right
Answer:
The answer would be 6 because 15/100 × 40/1 is 600/100 so 600 ÷ 100 is 6
There are 6 plastic beads on the clearance.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 b= 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of beads = 40
Percentage of plastic beads = 15%
The number of plastic beads.
= 15% of 40
= 15/100 x 40
= 3 x 2
= 6
Thus,
6 beads are plastic beads.

A study involves a population of 400 tall women. This population has a mean height of 179.832 cm and a standard deviation of 12.192 cm. If 50 of these women are randomly selected, find the probability that the mean for this sample group is above 182.88
Answer: 0.0386
Step-by-step explanation:
Given: The population of 400 tall women has a mean height[tex](\mu)[/tex] of 179.832 cm and a standard deviation[tex](\sigma)[/tex] of 12.192 cm.
Let X be a random variable that represents the height of woman.
Sample size : n= 50
The probability that the mean for this sample group is above 182.88 will be :
[tex]P(\overline{X}>182.88)\\\\=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{182.88-179.832}{\dfrac{12.192}{\sqrt{50}}})\\\\ =P(Z>1.7678)\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-P(Z<1.7678)\\\\=1-0.9614\ \ \ [\text{By p-value table}]\\\\= 0.0386[/tex]
Hence, Required probability = 0.0386
Elwin is attempting to read a 480 page book in 28 days. He reads the first 60 pages in 4 days. At this rate, will he finish the book in time? Show your work and/or explain your reasoning.
Answer:
No, he won't
Step-by-step explanation:
Given
Target = 480 pages in 28 days
Rate = 60 pages in 4 days
Required:
Determine if he'll reach his target
The rate can be expressed using:
[tex]Rate = \frac{Pages}{Days}[/tex]
So, we have:
[tex]Rate = \frac{60\ pages}{4\ days}[/tex]
Multiply the fraction by [tex]\frac{7}{7}[/tex]
[tex]Rate = \frac{60\ pages}{4\ days} * \frac{7}{7}[/tex]
[tex]Rate = \frac{60\ pages * 7}{4\ days * 7}[/tex]
[tex]Rate = \frac{420\ pages}{28\ days}[/tex]
This can be interpreted as: 420 pages in 28 days
And his target is 480 pages in 28 days
Hence, he wont finish the book at that rate

Write a rational inequality with the solution: (-2,-1)U(1, oo)
Answer:
[tex]\displaystyle \frac{x^2+3x+2}{1-x}<0[/tex]
Step-by-step explanation:
Rational Inequality
We are given the solution of rational inequality:
(-2,-1) U (1,∞)
The first set suggests a limited zone than can be obtained by a quadratic equation of the form:
[tex](x-a)(x-b)<0[/tex]
Where a and b are the roots of the equation, which coincide with the endpoints of the interval. Thus, to get the interval, we can use:
[tex](x+2)(x+1)<0[/tex]
Operating:
[tex]x^2+3x+2<0[/tex]
The second set is an open infinite interval, that can be modeled as a third binomial that changes signs in x=1 and is in the denominator, so x=1 is not included.
Thus, one possible inequality is:
[tex]\mathbf{\displaystyle \frac{x^2+3x+2}{1-x}<0}[/tex]
The solution to the inequality (-2,-1)U(1, ∞) is (-2, ∞)
Inequality
An inequality is an expression used to show the relationship between two or more numbers and variables.
A rational inequality is an inequality that contains a rational expression.

2x + 42 + 90 = 180
2x + 132 = 180
2x = 180 - 132
2x = 48
x = 48/2
x = 24
FOR VERIFICATION ONLY:2x + 42 + 90 = 180
2(24) + 42 + 90 = 180

Bill buys a new machine.
The value of the machine depreciates by 20% each year.
Bill wants to work out the value of the machine after 2 years.
By what single decimal number should Bill multiply the value of the machine when new?
Answer:
For a, the machine depreciates 20% of its current value each year. So, It will lose 20% of its value in the first year. Then in the second year, it will lose 20% of THAT value (not of the original value) and so on.
b) Since the machine loses 20% of its value each year, it retains 80% of its value each
Kim has a 15 meter head start and has a walking rate of 1.5 meters per second. Write an equation that gives the relationship between Kim's distance from the starting line d and the the time t.
Step-by-step explanation:
It is given that,
Distance, d = 15 m
Speed of Kim,v = 1.5 m/s
We need to find the equation that gives the relationship between Kim's distance from the starting line d and the time t. Speed of an object is given by :
speed = distance/time
⇒ [tex]t=\dfrac{d}{v}[/tex]
Putting all the values,
[tex]t=\dfrac{15\ m}{1.5\ m/s}\\\\t=10\ s[/tex]
Hence, this is the required solution.
