Determine whether the two lines are parallel, perpendicular, coinciding, or only intersecting.
y = - 3x + 8
6x + 2y =1
Choose the correct answer below.
parallel
only intersecting
perpendicular
coinciding

Answer:The discriminant is the expression b2 - 4ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. If you get a positive number, the quadratic will have two unique solutions.

Answer:

  see below

Step-by-step explanation:

You might do well to refer to the proof referenced here--the previous slide. We assume it more or less matches what we've done in the attachment.

Step-by-step explanation:

x - y = 6

x + y = 42

substitute

x = y + 6

( y + 6) + y = 42

2y + 6 = 42

2y = 36

y = 18

x = y + 6

x = 18 + 6

x = 24

Answer:

Range=9, Mean=4.125

Step-by-step explanation:

Mean is the average. To find the average, just add all the numbers and divide the total amount of numbers present in the set.

The range is the highest number minus the smallest numbers. In this set the range is 9.

Part A

(D) 100 ≤ 20x ≤ 1,000

Part B

[tex]\frac{100}{20}[/tex] ≤ [tex]\frac{20x}{20}[/tex] ≤ [tex]\frac{1000}{20}[/tex]

5 ≤ x ≤ 50

Answer:

:0 wowwwwwwww

Step-by-step explanation:

Answer:

If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.

< is angle

For the first one, <2+<3 equals 180

So, 37+<3=180. Rewrite that, and <3=180-37, which then <3 is 143 degrees

For the second one, COMPLEMENTARY ANGLES ADD UP TO 90 DEGREES

So, if one angle is 35 degrees, and we rewrite that again, 90-35 is it's complement.

So the answer to the second one is 90-35, 55.

Answer:

it should be 20 cans to make 5pounds

Answer:

(15, 15)

Step-by-step explanation:

Dilating by a scale factor of 5 centered at the origin simply multiplies the coordinates of a point by 5 so our answer is (3 · 5, 3 · 5) = (15, 15). Hope this helps!

Answer:

Shane collected 911 cans.

Step-by-step explanation:

S - represents Shane

S + (S + 178) ≥ 2000

2S + 178 ≥ 2000

*subtract 178 from both sides*

2S ≥ 1822

*divide both sides by 2*

S ≥ 911

Answer:

x is a variable

Step-by-step explanation:

what happens an squared plus B equals C and what I want to do is solve for a so again what we want to do is when we're taking solver a we want to isolate the variable get the variable by itself so the data that need to look at well what is happening on my variable a well you can see me as being multiplied by X and it's being added by B so I need to undo those but we got to make sure we undo them in a certain upper certain order which we call the reverse order of operations which is like the order of operations but the reverse method meaning I'm gonna undo addition or subtraction first so you can see that since my variable a is being added by B I need to undo that by subtracting B and I'll use my subtraction property of equality that's going to now subtract a 0 and then these C minus B are not like terms so I'm going to write ax is equal to C minus B now I need to solve for a so I need to look at and say alright my a is being x over X so the inverse operation of multiplying is dividing by X so therefore have a equals C minus B divided by X now sometimes you could say alright that's correct but we could also divide this X into both of these terms and I'm going to rewrite this in a different form I could say a equals C over X minus B over X alright so what I'm doing is are just dividing those through

Answer:

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... A slope with a greater absolute value indicates a steeper line. The direction of a line is either increasing, decreasing, horizontal or vertical.

Step-by-step explanation:

here are a few more things you might want to know will douing this

How do you know which slope is steeper?

When you look at the two lines, you can see that the blue line is steeper than the red line. It makes sense the value of the slope of the blue line, 4, is greater than the value of the slope of the red line, . The greater the slope, the steeper the line.

Can you create a line segment with infinite steepness?

An infinite slope is simply a vertical line. When you plot it on a line graph, an infinite slope is any line which runs parallel to the y-axis. You can also describe this as any line that doesn't move along the x-axis but stays fixed at one constant x-axis coordinate, making the change along the x-axis 0.

How does rate of change affect the steepness of a line?

The steepness of a line is essentially the slope. ... A negative slope would be depicted by a line going from the upper left to bottom right. Slope values increase the higher the number is: For instance, a line with a slope of 2 is steeper than a line with a slope of 12 . Hope this helps!Jun 20, 2018

What are the 3 slope formulas?

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

What is a 6% grade?

A road sign indicating a 6% grade, or 6% slope. A six percent slope means that the road elevation changes 6 feet for every 100 feet of horizontal distance (Figure 1.3). ... A road climbs at a gradient of 6 percent. The road gains 6 feet in elevation for every 100 feet of horizontal distance.

What does the slope represent?

The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x.
