Answer:
y = 4x – 10
Step-by-step explanation:
slope formula: [tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
point-slope formula: [tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]
Use slope formula and plug in your numbers: [tex]m = \frac{-18-6}{-2-4 }[/tex]Solve for slope [tex]m = 4[/tex]Use the point-slope formula to solve for the equation: [tex]y-6=4\left(x-4\right)[/tex]Solve and find equation: [tex]y=4x-10[/tex]Note: When given two points you only need to pick one for the point-slope formula!

Explain why Justine is correct or incorrect.
the second claim of justine is that the only angle of rotation that shows rotational symmetry is 120 degree is correct.
A rotational symmetry implies that the shape remains the same when rotated
Justine's claim is correct
How to determine the true statementThe angle of rotational symmetry is calculated as:
[tex]\theta = \frac{360}n[/tex]
Where n represents the number of sides.
From the complete question, the shape is a regular hexagon.
This means that n = 6.
So, we have:
[tex]\theta = \frac{360}6[/tex]
Divide
[tex]n = 60[/tex]
Other angles of rotational symmetry are:
[tex]n = 60, 120, 180, 240.....[/tex]
120 degrees is part of the list of possible angles of rotational symmetry.
Hence, Justine's claim is correct

(__,__)?
Answer:
(-3, 4)
Step-by-step explanation:
First, substitute y=-2x-2. We have 3(-2x-2)=9-x ---> -6x-6=9-x Then isolate the x. -5x=15 Simplify, we have x=-3. Then we can input this x-value back into one of the equations. We have 3y=9--3 ---> 3y=12 ---> y=4. So the solution to this system is (-3, 4).
Date : . The perimeter of Kite LIKE is 80 cm. The length of LI is 6cm less than Length of IK. Find the length of each side?
Answer:
lK = KE = 23cm
LI = LE = 27cm
Step-by-step explanation:
perimeter of kite LIKE =80cm
If IK=x cm
LI=(x-6) cm
Perimeter =2(a+b)
80 = 2(x+(x-6))
80 = 2(x+x-6)
80 = 2(2x-6)
80/2 = 2x-6
40 = 2x-6
2x = 40+6
2x = 46
x =46/2
x = 23
therefore,IK = 23cm
LI = 23-6 = 27cm

Find the measures of the interior angles of the triangle. Find A, B, C
Step-by-step explanation:
I am not sure what you mean by A, B, and C.
the picture does not name the corners or vertices.
but is seemingly asks for the angle x.
remember, the sum of all angles in any triangle is always 180°.
and the sum of all angles around one point on one side of a line is also 180° (as the line cuts a virtual circle in half with its center being the point around which the angles rotate).
when we know all angles except for one, we call the missing angle a supplementary angle (fills up to 180°).
if the angle fills up to 90°, we call that a complementary angle.
so, now look at the triangle. we know 2 angles : the right angle (90°) and the 38° angle.
so, the third angle down left must be
180 - 90 - 38 = 52°
and x is the supplementary angle to 52° :
x = 180 - 52 = 128°

how many natural numbers less than 50 have exactly 4 positive factors?
Options:
a) 13
b) 15
c) 17
d) 11
Answer:
15
Step-by-step explanation:
We will use the Tao function for our use. If there are 4 factors of a number then Tao function has a value of 4.
According to the Tao function, (a1 + 1)(a2 + 1).....(an + 1) = 4. So, by comparison We have two cases.
Case 1: a1 + 1 = 4
So, in that case a1 = 3 and we see there are two cubes less than 50.
Case 2: a1 + 1 = 2, a2 + 1 = 2
So, a1 = 1 and a2 = 1. Thus, it's a pure multiple of linear primes. And we notice there are 13 such numbers.

The sum of the numbers expressed in scientific notations is given by: Option B: [tex]6.82 \times 10^{12}[/tex]
How does scientific notations work?The number is written in the form [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
Better readability due to compact representationIts value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.The given expression is:
[tex](3.1 \times 10^5) \times (2.2 \times 10^7)[/tex]
Evaluating the multiplication, we get:
[tex]3.1 \times 2.2 \times 10^5 \times 10^7 = 6.82 \times 10^{5 +7} = 6.82 \times 10^{12}[/tex]
It is because of exponent rule that [tex]a^b \times a^c = a^{b+c}[/tex], and because of commutative property of addition.
Thus, the sum of the numbers expressed in scientific notations is given by: Option B: [tex]6.82 \times 10^{12}[/tex]

luke drives 35 mph for 5 miles. he then drives 80 mph for 30 seconds (0.0082 miles). what is his average speed?
ik the answer i just need to know how to do it
the answer is 55.56 mph
Answer:
Step-by-step explanation:
Average speed is total distance divided by total time.
The relation between time, speed, and distance is ...
time = distance/speed
Total timeThe time to travel 5 mi at 35 mi/h is ...
time = (5 mi)/(35 mi/h) = 1/7 h
30 seconds is (30 s)/(3600 s/h) = 1/120 h, so the total time for this trip is ...
1/7 +1/120 = (120 +7)/840 = 127/840 hours
Total distanceAt 80 mph, the distance traveled in 1/120 hour is ...
distance = speed × time = (80 mi/h)(120 h) = 2/3 mi
So, the total distance traveled is ...
(5 mi) +(2/3 mi) = 17/3 mi
Average speedThe average speed is then ...
speed = distance/time
speed = (17/3 mi)/(127/840 h) = 17·840/(3·127) mi/h = 37 61/127 mi/h
The average speed is about 37.48 miles per hour.
_____
Additional comment
In order for the average speed to be 55.56 mph, the time spent at 80 mph would need to be about 7 minutes 12.6 seconds, for a distance at 80 mph of about 9.61 mi.
suppose y=2x-16 and y=x+2. what is the value of x?
Step-by-step explanation:
Set two equations equal to each other
2x -16 = x+2
x = 18
Answer:
18
Step-by-step explanation:
Make the two equations to each other by subbing out the y
2x - 16 = x + 2
Move the like terms to one side
Subtract x from both sides
2x - 16 = x + 2
-x -x
x - 16 = 2
Add 16 to both sides
x - 16 = 2
+ 16 + 16
x = 18
X will have to be 18 for these equations to be true.
