The first coordinate is the x coordinate
X is 3 units to the left so it is -3
The next coordinate is the y coordinate
Y is 6 units down so it is -6

drag the ordered pair that are 5.5 units apart.
(-3, -3.5)
(5, 1.5)
(5, -3.5)
(-1.5, -3.5)
(-1.5, 2)
(-1.5, 2.5)
Answer:
(-1.5, -3.5) and (-1.5, 2)
Step-by-step explanation:
The x-coordinates in increasing order are ...
-3, -1.5, 5
The distances between pairs of these coordinates are ...
-1.5 -(-3) = 1.5
5 -(-3) = 8
5 -(-1.5) = 6.5
Clearly, any pair with x = 5 is too far away from any pair with a different x-value.
∆x = 1.5
If the distance between pairs is 5.5, then the distance formula tells us the y-coordinate differences for pairs with x-coordinates of -3 and -1.5 must be ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
5.5 = √(1.5^2 +(y2 -y1)^2) . . . substitute known values
30.25 = 2.25 +(y2 -y1)^2 . . . . square both sides
√28 = (y2 -y1) . . . . . . . . . . . . . . subtract 2.25 and take the square root
This value is irrational. Clearly none of the y-coordinates is irrational, so there are no point pairs with x-coordinates -3 and -1.5 that are 5.5 units apart.
__
∆x = 0
If the x-coordinates are the same, then the y-coordinates must differ by 5.5 in order for the points to be 5.5 units apart. The coordinates in order are ...
for x = -1.5, y = -3.5, 2, 2.5 . . . . . differences of 5.5, 6, 0.25
for x = 5, y = -3.5, 1.5 . . . . . . . difference of 5
The only pair we can find that is 5.5 units apart is ...
(-1.5, -3.5) and (-1.5, 2).

Answer and Explanation:
Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:
x = 4√(2)
y = 2(4) = 8
because where 4 = T,
x = T√2 and y = 2T
so again:
[tex]x = 4\sqrt{2}\\y = 8[/tex]

A. 5. Incorrect. 5 is not long enough for y.B. 8. Correct. Just the right size for y.C. 4. Incorrect. 4 is already in there, so this is incorrect.D. 2. Incorrect. Not even close to fit y.Your answer is B.
area of a triangle when b = 6 m and h=7 m
Answer
42
Step-by-step explanation:
The area of a triangle is "triangle = BxH" Which in your case is 6x7
Answer:
21 square units
Step-by-step explanation:
Triangle area is [tex]\frac{b*h}{2}[/tex]
so, [tex]\frac{6*7}{2} =\frac{42}{2} =21[/tex]
so, area is 21 square units

Solve for the following function.
y = x + 3 when x = 0, 1, 2, 3
A. (0, -3) (1, -4) (2, -5) (3, -6)
B. (0, 3) (1, 4) (2, 5) (3, 6)
C. (3, 0) (4, 1) (5, 2) (6, 3)
D. (-3, 0) (-4, 1) (-5, 2) (-6, 3)
Answer:
B. (0, 3) (1, 4) (2, 5) (3, 6)
Step-by-step explanation:
An ordered pair is (x, y). So the first number in the first ordered pair is x=0, or (0, _).
The value of y is 3 more than the value of x, so the first ordered pair is (0, 3). This matches answer choice B.
What is the Y intercept and the slope of the equation Y=3-1/2x
Answer:
3
Step-by-step explanation:
y = 3 - 1/2x
rewrite equation so the slope is in front
y = -1/2x + 3
plug in 0 for x
y = -1/2(0) + 3
solve for y
y = 0 + 3
y = 3
y- intercept = (0,3)
Step-by-step explanation:
Since this equation is in slope-intercept form, we can easily identify what the slope is, and the y-intercept.
Slope intercept form: y = mx + b
m = slope
b = y intercept
Switch the coefficient and 3:
y = -1/2x + 3
-1/2 = Slope
3 = Y-intercept
Note: If we're asked to graph, using this equation will allow us to graph without solving.

Approximately what is the percent of decrease in the price of gummy bears?
Group of answer choices
Based on the information given, the reduction in the percentage of the bag is 62.6%.
How to solve percentageFrom the information, a bag of Halloween-themed gummy bears sells for $4.78 and after Halloween, a bag sells for $1.79.
The percentage decrease will be:
= (4.78 - 1.79) /4.78 × 100
= 2.99/4.78 × 100

A ball is thrown from an initial height of 1 meter with an initial upward velocity of 11 m/s. The ball's height h (in meters) after t seconds is given by the following.
h=1+11t-5^2
Find all values of t for which the ball's height is 6 meters.
Round your answer(s) to the nearest hundredth.
Answer:
[tex]t=0.64[/tex] and [tex]t=1.56[/tex] seconds
Step-by-step explanation:
[tex]h=1+11t-5t^2\\\\6=1+11t-5t^2\\\\0=-5+11t-5t^2\\\\0=-5t^2+11t-5\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-11\pm\sqrt{11^2-4(-5)(-5)}}{2(-5)}\\\\t=\frac{-11\pm\sqrt{121-100}}{-10}\\ \\t=\frac{-11\pm\sqrt{21}}{-10}\\\\t=\frac{11}{10}\pm\frac{\sqrt{21}}{10}\\ \\t_1\approx0.64\\\\t_2\approx1.56[/tex]

A line has 2/3 and y intercept -2 which answer is the equation of the line
Answer:
A line has a slope of 2/3 and y–intercept -2. The equation of the line is y = (2/3)x - 2.
Step-by-step explanation:
Hope this helps
Answer:
y = (2/3)x - 2
Step by step explanation:
The slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate of that line.
Given, slope of the line is 2/3
y-intercept is -2.
The equation of the line in slope-intercept form is given by
y = mx + c
Where, m is the slope
c is the y-intercept.
y = (2/3)x - 2
