Q(2, a) is 5 units away from P(–2, –1). Find all possible values of a.
Answer:
a = 2
Step-by-step explanation:
Here, we want to find all the possible values of a
If Q is 5 units away from P, then the distance between Q and P is 5 units
Mathematically, to find the distance between two points, we use the following formula
D = √( (x2-x1)^2 + (y2-y1)^2
So we have ;
D = √(2-(-2)^2 + (a-(-1)^2
D = √(16) + (a + 1)^2
Since D is 5, we have
5 = √(16) + (a +1)^2
Squaring both sides to remove the square root, we have
25 = 16 + (a + 1)^2
(a + 1)^2 = 25 - 16
(a + 1)^2 = 9
(a + 1)^2 = 3^2
Since power is equal, equate base
a + 1 = 3
a = 3-1
a = 2

What is the missing addend?
52,835 +
= 87,216
Answer: 34,381
Step-by-step explanation:
You have to subtract 52,835 by the sum 87,216 which will get you the answer of 34,381
The missing addend is 34,381.
87,216-52,835=34,381
How many solutions y=5x-4 y=5x-5
Answer:
No solution
Step-by-step explanation:
Any equations with the same slope are parallel, or will never intersect.
In a slope-intercept equation, this would mean the 'm' values are the same.
y = mx + b
Two equations:
y = 5x - 4
y = 5x - 5
Since the two equations given have the same slope, they will never intercept and therefore have no solution.

Answer:
The direction matters , but only in sign... so from A to A' is what i'm guessing is the direction of translation
Step-by-step explanation:
find the vector from A to A' or any of the other non prime to prime points.. the vector will be the same... soooo
take the origin point as P1 , then take the destination point a P2
and subtract P2-P1
P2 = A' = (6,-2)
P1 = A = (2, 1)
(6-2, -2-1) = (4,-3)
your vector can be place at the origin.. and go 4 in the x direction and -3 in the y direction and you get that translation.. make sense?

Answer:
1 is 87 and 2 is 93
Step-by-step explanation:
idrk exactly how to explain it....but i'll try....
the 87 is part of a straight angle, so the one to the left of it, that angle is 93.
1 is diagnoly oppisite of the 87, so 1 is 87. 2 is diagnoly oppisite of the other part of the striaght angle(93), so its 93

Which value of x satisfies the equation
5/6 (3/8 - x)
= 16
Answer:
[tex]x = - 18.825[/tex]
Step-by-step explanation:
[tex] \frac{5}{6}( \frac{3}{8} - x)
= 16 \\ \frac{(5)(3)}{(6)(8)} - \frac{5x}{6} = 16 \\ 15 - 40x = 768\\ 40x = 15 - 768\\ x = - 18.825[/tex]
The value of x for the equation to be equal is- 40/753
Solution to linear equationGiven the linear equation expressed as:
5/6 (3/8 - x) = 16
Open the parenthesis
5/16 - 5/6x = 16
Collect the like terms
-5/6x = 16 - 5/16
-5/6x = 251/16
Cross multiply
1506x = -80
x = -80/1506
x = -40/753
Hence the value of x for the equation to be equal is- 40/753

The pre-image and image of what transformation are not congruent?
O A. dilation
O B. reflection
O C. translation .
O D. rotation
Answer:
Option A
Step-by-step explanation:
Options B, C, and D are examples of ridged transformations. Ridged transformations are transformations that keep the pre-image and image congruent.
A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation.
Hope this helps.
The correct options are Reflection, Translation and Rotation.
What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Reflection, Translation and Rotation are examples of rigid transformations, and we know that a rigid transformation is a transformation that doesn't change the size or shape of a geometric figure, a special kind of transformation that doesn't change the size or shape of a figure.
There are three different types of transformations: translation, reflection, and rotation.
Whereas,
A dilation would change the actual size of the pre-image to make the image, so they would be not congruent in a dilation, it can enlarge or shrink the image.
Hence, Reflection, Translation and Rotation are the transformation which preserve the preimage.

Answer:
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
The relation R is not a function
Step-by-step explanation:
Relations and Functions
We are given the ordered pairs of a relation, let's call it R:
R={(-3, 2), (-2, 2), (1, 2), (-3, 1), (0, 3)}
The domain of R is the set of values that relate to 1 or more elements from the range.
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
Note the value 2 is repeated in the second set, but it's reported only once as part of the Range.
A relation is a function if each element of the domain appears in only one ordered pair, or relates to a single element in the Range.
The relation R is not a function, because the ordered pairs (-3, 2) and (-3, 1)
map the element -3 twice.
-3x-4=-5y-8 what is the y-intercept and x-intercept
Answer:
3/5x + 4/5 = y
or
y = 3/5x + 4/5
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the y-intercept just need to put 0 instead of x in the equation.
[tex] - 3(0) - 4 = - 5y - 8[/tex]
[tex] - 4 = - 5y - 8[/tex]
Add sides 8
[tex] -4 + 8 = - 5y - 8 + 8[/tex]
[tex] 4 = - 5y[/tex]
Divide sides by -5
[tex] \frac{4}{ - 5} = \frac{ - 5}{ - 5} y \\ [/tex]
[tex]y = - \frac{4}{5} \\ [/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the x-intercept just need to put 0 instead of y in the equation.
[tex] - 3x - 4 = - 5(0) - 8[/tex]
[tex] - 3x - 4 = - 8[/tex]
Add sides 4
[tex] - 3x - 4 + 4 = - 8 + 4[/tex]
[tex] - 3x = - 4[/tex]
Negatives simplifies
[tex]3x = 4[/tex]
Divide sides by 3

Find the value of x?
Answer:
x = 94°
Step-by-step explanation:
interior angle sum of any polygon: (s-2)×180°
with s being the number of sides.
since there are 7 sides, 7-2 = 5
5* 180°
900° = total sum
______________________________
since we know the rest of the angles, just subtract the total sum from the sum of the known angles to find the unknown one.
900°-(148°+140°+136°+142°+150°+90°) = x
900°- 806°= 94°
x= 94°

The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?
0.1 m/s
9.65
1040m/s
0.1s
Answer:
Time, t = 9.615 secs.
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex] ....equation 1
[tex]Time = \frac{distance}{speed}[/tex] .....equation 2
Given the following data;
Distance = 100m
Speed = 10.4m/s
Substituting into equation 2;
[tex]Time = \frac{100}{10.4}[/tex]
Time, t = 9.615 secs.
