Answer:
It will be 381. You round up if it is five and over, and round down if 5 and below.
Step-by-step explanation:
A decimal cannot be a whole number so rounding to the nearest whole number means getting rid of the decimal. You do this by rounding up if it 5 and up, and rounding down if it is 5 and below. 380.5 means you would round up to 381. If it it were 380.4, you would round down to 380.
Answer:
381
Step-by-step explanation:
any number 5 and over will round up

Which is a solution for 4 x + 8 = 3 x + 14?
Answer:
x=6
Step-by-step explanation:
Step 1:
Subtract 3x from both sides:
4x + 8 - 3x = 3x + 14 - 3x
x + 8 = 14
Step 2:
Subtract 8 from both sides:
x + 8 - 8 = 14 - 8
x = 6
The table shows the cost of movie tickets based on the number of tickets purchased. PLEASE HELP ME
Number of Tickets Cost
2 $17.00
3 $25.50
4 $34.00
5 $42.50
Based on this proportional relationship, find the constant of proportionality (r). Using the value for r, enter an equation that will calculate the cost (y) of x movie tickets in the form of y=rx. The answer is not y=8.5 Please help the one who gives me the correct answer will get brainliest
The proportional relationship is given by y = 8.5x
Two variables are said to be proportion if an increase/decrease in one variable causes an increase/decrease in the other variable.
Let x represent the movie tickets and y represent the cost.
Since x and y are proportional, hence:
y ∝ x
y = rx
Where r is the constant of proportionality.
From the table to find x, when y = 17, x = 2, hence:
17 = 2r
r = 8,5
y = 8.5x
The proportional relationship is given by y = 8.5x

6. Write the equation of a line with a y-intercept of 2 and a slope of - . Graph the equation. 3
Answer:
y = 3/4x + 2
Step-by-step explanation:
May I please receive help?
Original line: y = -5/6x - 1
A line that is parallel to the original will have the same slope. To find the new y-intercept, we'll take the original line, plug in the given point, and solve for b.
y = -5/6x + b
-2 = -5/6(5) + b
-2 = -25/6 + b
b = 13/6
Parallel Line: y = -5/6x + 13/6
A line that is perpendicular to the original will have the opposite reciprocal slope. To find the new y-intercept, we'll take our perpendicular slope, plug in the given point, and solve for b.
y = 6/5x + b
-2 = 6/5(5) + b
-2 = 6 + b
b = -8
Perpendicular Line: y = 6/5x - 8

Yeah bit confused need help
Answer:
[tex]x = \frac{1}{2}y[/tex] or [tex]y = 2x[/tex]
Step-by-step explanation:
Basically, x is 2 times smaller than y, or
y is 2 times larger than x.
For example, when x equals 4, y is 2 times greater, so y = 4 * 2 = 8
Another example:
When y equals 12, x must be 2 times smaller than that, so x = 12 / 2 = 6
I don't know which one you're looking for, but try putting in
x = 1/2y or y = 2x

Find the equation of a line parallel to y=2x-4 that contains the points (1,-1)
Answer:
y=2x-3
Step-by-step explanation:
refer to picture plz
Answer:
the desired equation is y = 2x - 3
Step-by-step explanation:
Parallel lines have the same slope. Thus, a new line parallel to y = 2x - 4 has the slope 2.
Find the equation of the new line by writing out the slope-intercept form
y = mx + b. Substitute -1 for y and 1 for x:
-1 = 2(1) + b, which yields b = -3
Then the desired equation is y = 2x - 3

Find the value of x. Find the measures of the two supplementary angles
Answer:
x = 32
<1 = 102 degrees
<2 = 78 degrees
Step-by-step explanation:
3x + 6 + 2x + 14 = 180
5x + 20 = 180
5x = 180 - 20
x = 160/5
x = 32
3(32) + 6 = 102 degrees
180 - 102 = 78 degrees

Answer: - 4d
Step-by-step explanation:
In the equation, there's an invisible 1 in front of the first d, so let's add that.
1d - 2d - 3d
Since all the terms in the above equations are like terms, we would focus on only subtracting. We would first subtract 2d from 1d.
- 1d - 3d
We then subtract 3d from - 1d. This would give us our answer.
- 4d

Explanation:
Parallel lines always have equal slopes, but different y intercepts. For example, the two lines y = 3x+5 and y = 3x+7 have a slope of 3. Refer to y = mx+b where m is the slope. Parallel lines never intersect.
-----------
For perpendicular lines, the two slopes always multiply to -1 assuming neither line is vertical nor horizontal. Consider the two linear equations
y = (1/2)x+5
y = -2x-7
The slopes 1/2 and -2 multiply to -1 which is enough to show that they are perpendicular lines. The two lines meet at a 90 degree angle.
To go from one slope to the other, we apply the negative reciprocal. That means we...
flip the fractionflip the signApplying the first step to 1/2 gets us 2/1 or 2. Then changing the sign has us go from 2 to -2. This process can be reversed.
-----------
For some of these equations, you'll need to rearrange things into either point-slope form or slope intercept form. This will allow you to read off the slope.
Point slope form is y-y1 = m(x-x1)
Slope intercept form is y = mx+b
For either case, all we care about is the variable m.
I'll show how problem 14 transforms into slope intercept form
x+2y = 14
2y = -x+14
y = (-x+14)/2
y = (-x/2) + (14/2)
y = (-1/2)x + 7
We see that m = -1/2 here. Anything parallel to this will have the same slope. The perpendicular slope is 2 after applying the negative reciprocal operation. Problems 13, 15, 16, 17, and 18 are going to follow similar steps.
