Answer: c) y = 9/4 · x
Step-by-step explanation:
We can use slope formula to find the slope of a line that passes through two points (x₁ , y₁) and (x₂ , y₂)
m = ∆y/∆x = y₂-y₁/x₂-x₁Given points are: P(x₁ , y₁) = (0, 0) and Q(x₂ , y₂) = (-4, -9)
Substituting these two known points in the slope formula, we have:
m = (-9-0)/(-4-0) = -9/-4 = 9/4Now we can use the point-slope formula to write the equation of a line given a point on the line and the slope of the line:
m = 9/4 , given point P(x₁ , y₁) = (0, 0)
Formula = (y-y₁) = m(x-x₁) (y-0) = 9/4(x-0) y = 9/4 · xAnswer: c) y = 9/4 · x

Solve the following absolute value equation in the work space. Be sure to circle
your answer(s).
|3t +3|=18
Answer: so the answer t= 5, -7
3t + 3 = 18
( we subtract 3 from both sides)
3t + 3 = 18
- 3 -3
3t = 15
( then we divide both sides by 3 )
3t/3 = 15/3
t = 5
(and this is the negative part, we do most of the same steps as teh last one)
3t + 3 = -18
- 3 -3
3t = -21
3t/ 3 = -21/ 3
t = -7

What is the ratio of 3:6
Answer:
1:2
Step-by-step explanation:
You didn't really specify, but I'm going to assume you meant as simplified as possible. If you write it as a fraction, it will be ½ or as a decimal it will be 0.5.
Answer:
1:2
Step-by-step explanation:
Simplifying a ratio is like simplifying a fraction.
Simply put the number to the left as the numerator, and the number to the right as the denominator.
In this case, 3/6 = 1/2.
Hence, plug the numbers right back in and you get 1:2.

Answer:
The answer is x = 6.
Step-by-step explanation:
The middle line is 2, and the leg is [tex]\sqrt{13}[/tex]. We can use the pythagorean theorem and use [tex]\sqrt{13}[/tex] as the hypotenuse and have 2 be a leg.
[tex]a^{2} + b^{2} = c^{2} \\\\2^{2} + b^{2} = \sqrt{13}^{2}[/tex]
[tex]4 + b^{2} = 13\\\\b^{2} = 9\\b = 3[/tex]
Since we know one of the bottom parts of x is 3, and the other triangle is the same as the on we solve, we do 3 + 3 which is 6. 6 is equal to x.

jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. which expression can he use to figure out the number of holes he will need to drill
Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes

Please help me to solve this quadratic equation.
Don't answer if you don't know.
Answer:
The answer is m=-2 or m=7.
Step-by-step explanation:
The steps to solve this equation are below:
Factor: to get (m+2)(m−7)=0.
m+2=0 or m−7=0
m=−2 or m=7. So, your answer is m=-2 or m=7.
Answer:
m = 7
m = -2
Step-by-step explanation:
ax^2 + bx + c
1m^2 - 5m - 14
a = 1
b = -5
c = -14
-b ± √b^2 - 4ac/2a
-(-5) ± √(-5)^2 - 4(1)(-14)/2(1)
5 ± √25 + 56/2
5 ± √81/2
5 ± 9/2
5 + 9/2
14/2 = 7

x+y=5
2x-y=-2
WILL GIVE BRAINLIEST
Answer:
(x, y) = (1, 4)
Step-by-step explanation:
Given: x+y=5 and 2x-y=-2
Solve for y and x
x+y=5; solve for y
y = 5 - x; substitute into other equation
2x-y= -2
2x - (5 - x) = -2
2x - 5 + x = -2; combine x's
3x - 5 = -2; add 5 to both sides
3x =3; divide by 3
x = 1; use this to solve for y
x+y=5
1 + y = 5; subtract 1 from both sides
y = 4
(x, y) = (1, 4)

what does 9a-2=12+2a
Answer:
a=2
Step-by-step explanation:
Subtract 2a from both sides.
9a−2−2a=12
Combine 9a and −2a to get 7a.
7a−2=12
Add 2 to both sides.
7a=12+2
Add 12 and 2 to get 14.
7a=14
Divide both sides by 7.
a=[tex]\frac{14}{7}[/tex]
Divide 14 by 7 to get 2.

1/5 part of pole is inside the mud, 2/3 part is inside the water and the remaining length of 10m is above the surface of the water. Find the length of the pole.
Answer:
75 m
Step-by-step explanation:
Let the length of the pole to be : x m
1/5 of x is inside the mud, this will be : 1/5 x
2/3 of x in inside water , this will be : 2/3 x
10 m remaining is above the water surface. Finding the fraction that remains will follow;
x - {1/5 x + 2/3x } = 10
x-13/15 x =10
2/15 x = 10

[tex]\large\boxed{tan\text{ } (\frac{-\pi }{6})}[/tex]
**Recall that tangent is Opposite / Adjacent**
tan (5π / 6) according to the unit circle equals -1 / √3. We can go through each choice and eliminate:
tan (-5π / 6) is in the third quadrant which would mean that the value would be positive 1 / √3. This choice is incorrect. tan (7π / 6) is the same as tan (-5π / 6), which is positive 1 / √3. This choice is incorrect.cot (5π / 6) is the reciprocal of tan 5π / 6, which is incorrect.tan (-π / 6) is equal to -1 / √3. This choice is correct.Therefore, the correct choice is tan (-π / 6).
