Answer:
y + 5 = ¹/₆(x - 1)Step-by-step explanation:
The slope of a line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(1, -5) ⇒ x₁ = 1 , y₁ = -5
(-5, -6) ⇒ x₂ = -5 , y₂ = -6
[tex]m=\dfrac{-6+5}{-5-1}=\dfrac{-1}{-6}=\dfrac16[/tex]
Point-slope form of equation of a line with givem slope m and passing through point (x₁, y₁): [tex]y-y_1=m(x-x_1)[/tex]
(1, -5) ⇒ x₁ = 1 , y₁ = -5
Therefore:
[tex]y-(-5)=\frac16(x-1)\\\\\underline{y+5=\frac16(x-1)}[/tex]

Cora is playing a game that involves flipping three coins at once let the random variable H be the number of coins that land showing heads. Here is the probability distribution for H.
Answer:
[tex]P(H <3) = 0.875[/tex]
Step-by-step explanation:
Given (Missing from the question):
[tex]\begin{array}{cc}{H}&{P(H)&0&0.125&1&0.375&2&0.375&3&0.125\end{array}[/tex]
And the required question is:
Determine the P(H < 3)
P(H <3) implies that: P(H = 0) or P(H = 1) or P(H = 2)
So, we have:
[tex]P(H <3) = P(H = 0) + P(H = 1) + P(H = 2)[/tex]
[tex]P(H <3) = 0.125 + 0.375 +0.375[/tex]
[tex]P(H <3) = 0.875[/tex]

Is 2(6 – 3x) + x equivalent to 2(3x) + x + 12?
Answer:
Step-by-step explanation:
Carry out indicated operations to see if they are equal
2(6-3x)+x=2(3x)+x+12
2(6)+2(-3x)+x=6x+x+12
12-6x+x=6x+x+12 combine like terms on both sides
12-5x=12+7x (we can see here they are unequal but we can continue) subtract 12 from both sides
-5x=7x divide both sides by x
-5=7
7 is not equal to -5 so the original expressions aren’t equivalent.

Virginia needed some batteries for her flashlights. She bought 4 batteries for $6.80. At that rate, how much would 10 batteries cost?
Answer:
$17
Step-by-step explanation:
First find the cost of 1 battery.
$6.80 ÷ 4 = $1.70
Then multiply the cost of one battery by 10.
$1.70 x 10 = $17
Answer:
10 batteries would cost $17
Find the length of the shorter leg in the triangle pictured below
x=6
x=24
X=12
X=12 square root 3
X=36
Answer:
b. x=24
Step-by-step explanation:
There are special formulas for finding the sides of a 30-60-90 triangle. The hypotenuse is always equal to 2a and the long leg is always equal to [tex]a\sqrt{3}[/tex].
Since side a is given already as 12. We can substitute 12 for a.
2(12) = 24

Unit 4 Homework 2 Gina Wilson all things algebra,
Pls help!
Answer:
1. m∠1 = 48°
2. m∠1 = 129°
3. m∠1 = 37°
4. m∠1 = 88°
m∠2 = 42°
m∠3 = 113°
5. m∠1 = 72°
m∠2 = 35°
m∠3 = 24°
6. m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 133°
m∠5 = 81°
7. m∠1 = 41°
m∠2 = 85°
m∠3 = 95°
m∠4 = 85°
m∠5 = 36°
m∠6 = 49°
m∠7 = 106°
8. x = 12°
9. x = 9°
10. x = 5°
11. x = 7°
Step-by-step explanation:
1. 76° + 56° + m∠1 = 180°
∴ m∠1 = 180° - (76° + 56°) = 48°
m∠1 = 48°
2. m∠1 = 67° + 62° = 129°
m∠1 = 129°
3. m∠1 = 152° - 115° = 37°
m∠1 = 37°
4. m∠1 = 180° - (52° + 42°) = 88°
m∠1 = 88°
m∠2 = 42°
m∠3 = 180 - (42° + 25°) = 113°
m∠3 = 113°
5. m∠1 = 180° - 118° = 72°
m∠1 = 72°
m∠2 = 180° - 72° - 73° = 35°
m∠2 = 35°
m∠3 = 73° - 49° = 24°
m∠3 = 24°
6. m∠5 = 180° - m∠52° - m∠47° = 81°
m∠5 = 81°
m∠1 = 81° + 47° = 128°
m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 180° - 47° = 133°
m∠4 = 133°
7. m∠3 = 95°
m∠5 = 180° - 144° = 36°
m∠5 = 36°
m∠6 = 180° - 95° - 36° = 49°
m∠6 = 49°
m∠4 = 180° - 95° = 85°
m∠4 = 85°
m∠2 = 85°
m∠7 = 360° - (38° + 85° + (180° - 49°)) = 106°
m∠7 = 106°
m∠1 = 360° - (85° + 90° + 144°) = 41°
m∠1 = 41°
8. (10·x - 11)° + (3·x - 2)° + (3·x + 1)° = 16·x° - 12° = 180°
16·x = 180°+ 12° = 192°
x° = 192°/16 = 12°
x = 12°
9. (3·x - 5)° + (7·x + 5)° + 90 = 180°
10·x + 90° = 180°
10·x = 180°- 90° = 90°
10·x = 90°
x = 90°/10 = 9°
x = 9°
10. 180 - 151 = 29°
(11·x - 1)° + (20·x - 3)° + 29° = 180°
31·x° + 25° = 180°
31·x° = 180° - 25° = 155°
31·x° = 155°
x = 155/31 = 5°
x = 5°
12. (4·x + 13) + (6·x + 2) + 180 - (14·x - 13)
208° - 4·x° = 180°
208° - 180° = 4·x°
28° = 4·x°
4·x° = 28°
x = 28°/4 = 7°
x = 7°.
5 t-shirts and a hat costs £62.00
2 t-shirts and a hat costs £29.00.
How much does a t-shirt cost?
How much does a hat cost?
Answer:
T-shirt : £11
Hat : £7
Step-by-step explanation:
Think of T-shirts as T
and Hats as H
5t + h = 62
2t + h = 29
we then subtract them both to cancel out h
3t = (62-29) = 33
now we divide 33 by 3 to find one t
33/3 = 11
so one t shirt is £11.00
now we substitute it back into the equation
2t ( 2x11 ) = 22
22 +h = 29
29 - 22 = 7

Find the value of X ?
Answer:
x = 19
Step-by-step explanation:
(10x - 23) and (7x + 34) are vertically opposite angles and congruent, so
10x - 23 = 7x + 34 (subtract 7x from both sides )
3x - 23 = 34 ( add 23 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19

Angle ABD is 52°. State the size of angle DEB, giving a reason for your answer.
Answer:
∠ DEB = 52°
Step-by-step explanation:
The angle between a tangent and a chord is equal to the angle in the alternate segment, that is
∠ DEB = ∠ ABD = 52°
The short answer is that you use the tangent-chord theorem. A more lengthy answer is given below.
=================================================
Explanation:
Refer to the diagram below.
I'm going to move point E so that segment EB becomes a diameter of the circle (it goes through the center point F). Points A,B,C,D will stay in place. The red points and red segments show the changes.
In this slightly redrawn diagram, triangle EDB is a right triangle where angle EDB is 90 degrees. This is due to Thales Theorem, which is a special case of the inscribed angle theorem.
Also, the new segment EB is perpendicular to segment AC because the diameter touching the point of tangency is perpendicular to the tangent line. So angle EBA is 90 degrees.
Since points A, D and B didn't move, this means angle ADB is still 52 degrees. This makes the new angle EBD equal to 90-52 = 38 degrees.
Despite the fact that angle E has moved, it has not effected the size of angle DEB. This angle is the same as its original because we're still subtending the same minor arc DB, and that arc hasn't changed size (since segment DB hasn't changed). So that's why it's valid to use the same x for the old angle DEB in black and the new angle DEB in red. They're the same angle.
-------------
Focus on triangle EBD. We have the following interior angles
B = 38D = 90E = xFor any triangle, the three interior angles must add to 180
B+D+E = 180
38+90+x = 180
128+x = 180
x = 180-128
x = 52
Angle DEB is 52 degrees
It's not a coincidence that we end up with the same angle as shown in the original diagram. The tangent-chord theorem says that the angle between a chord and tangent (as shown in the diagram) is exactly equal to the inscribed angle that subtends the arc formed by the chord. Arc DB is formed by chord DB.
In short, the tangent-chord theorem says that inscribed angle DEB and angle ABD are the same measure (both are 52 degrees).
This demonstration I've shown is one way to prove the tangent-chord theorem. Though a more rigorous proof would involve another variable.
