revious Question
Answers
y = 4x - 28
Step-by-step explanation:
When two lines are parallel, their slope stays the same. thus we have y = 4x (so far)
Then use the point (8, 4) to plug in the coordinates to y = 4x + b
y = 4x + b (because y-intercept changes)
4 = 4(8) + b
4 = 32 + b
b = 4 - 32
b = -28
the y-intercept is -28 and the equation of the line that passes through the point (8, 4) and is parallel to the line y = 4x + 2 is y = 4x - 28
A school gym is set up for an
assembly. There are 17 rows with 28
chairs in each row. Parents are sitting
in half the chairs, but the other half
are empty. How many chairs are empty?
Answers
17 rows•28 chars per row=476 chairs total
476 chairs/2(because half are empty)=238 empty chairs.
Answer:
238 chairs are empty
Step-by-step explanation:
Firstly,
you'll have to times 17 by 28 to get the total chairs in the school gym
17 × 28
= 476
Next,
divide it by 2 because half of the gym???
476/2
= 238
So, the amount of the empty chairs in the school gym are 238 in total ｡◕‿◕｡

3-1/8a=1/4
Pleasseeee help
Answers
The goal is to isolate "a" and its coefficient to make the simplification process easier.
Start by subtracting 3 from both sides:
3 - 3 - 1/8a = 1/4 -3
-1/8a = 1/4 - 3
Next, multiply 3 by 4/4 to convert it into a fraction:
-1/8a = 1/4 - [3 • (4/4)]
-1/8a = 1/4 - 12/4
-1/8a = - 11/4
Multiply both sides by -8:
(-8) -1/8a = - 11/4 (-8)
a = 88/4 = 22
Therefore, a = 22.

75.3325 round to the tenth
Answers
the first 3 is in the tenths place, the second 3 is in the hundredths place, the 2 is in the thousandths place, and the 5 is in the ten thousandths place.
now since you know that the 3 is in the tenths place you have to look at the number in the hundredths place so you know what to round it to. since the number in the hundredths place is below 5, it stays the same. if it were a 5 or above, that 3 would be rounded to a 4 making the answer 75.4, but since it’s a 3, the answer stays 75.3
Why might you write the equation in
point-slope form instead of slope-intercept
form?
Answers
Step-by-step explanation:
Slope-intercept form is useful when we know the y- intercept of a line. However, we are not always given this information. When we know the slope and one point which is not the y-intercept, we can write the equation in point-slope form.
I hope this will help you out!
The equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point slope form.
We need to check why might we write the equation in point-slope form instead of slope-intercept form.
What is point-slope form?Point slope form is used to represent a straight line using its slope and a point on the line. That means, the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point slope form. Different forms can be used to express the equation of a straight line. One of them is point slope form. The equation of the point slope form is: y - y1 = m(x - x1)
where, (x, y) is a random point on the line and m is the slope of the line.
The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as: y = mx + b.
We use point-slope form with one coordinate and slope.
Therefore, the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point slope form.

Step-by-step explanation:
Correct on edge
The function will be one-to-one only if c = 13.
When a function is one-to-one?
A function is one-to-one if and only if each value in the range appears only once.
So, the given set will represent a one-to-one function if c takes a value that is not repeated in any of the other coordinate pairs.
We have:
(1, 2), (2, 3), (3, 5), (4, 7), (5, 11), (6, c)
For the given options, the only element that not already appears in one of the pairs is c = 13, so that is the correct option.

Answers
Answer:
1: C) Yes, because the last digit is 6, which is divisible by 2
2: B) Yes, because the sum of 2+1+6=9, which is divisible by 3
3: C) Yes, because the last digit of the number is 0
Step-by-step explanation:
Let's start with the first one. Is 26 divisible by 2? Yes, it is, because the last digit is 6, which is divisible by 2. To check to make sure we are right, we simply divide 26 by 2. Can it be done? Yes, 26 divided by 2 is 13, so we are right.
What about number two? Is 216 divisible by 3? Well, the rules divisiblity rules change for 3. For three, the sum of the digits of the number must be divisible by three. Do 2, 1, and 6, when added together, equal a number that is divisible by 3? Well, 2+1+6 is 9, and 9 is divisible by three, so the answer is B.
For the last one we need to check the divisibility rule for ten. The rule is that if the number ends in 0, it is divisible by 10. Does 40,100 end in a zero? Yes, so the answer is C.
