What is the equation of the line that passes through the point (8,-8 and has a slope of -1/4
Answer:
The answer is
[tex] \huge y = - \frac{1}{4} x - 6[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is ( 8 , - 8) and slope -1/4
We have
[tex]y + 8 = - \frac{1}{4} (x - 8) \\ y + 8 = - \frac{1}{4} x + 2 \\ y = - \frac{1}{4} x + 2 - 8[/tex]
We have the final answer as
[tex]y = - \frac{1}{4} x - 6 \\ [/tex]

6x-4=3x+4 i need help doing this
Answer:
x=2.666 repeated
Step-by-step explanation: this is correct, pls mark brainliest. take -4 and add it to the other side(+4). 6x=3x+8. subtract 3x from 6x. 3x=8. take 3x and devide it on bolth sides. x=2.666 repeated
Answer:
x = 3/8
Step-by-step explanation:
6x -4 = 3x + 4
Step 1 - Add 4 on both sides
6x -4 = 3x + 4
+ 4 + 4
6x = 3x + 8
Step 2 - Subtract 3x on both sides
6x = 3x + 8
-3x -3x
3x = 8
Step 3 - Divide 3 on both sides
3x = 8
÷3 ÷3
Answer - x = 3/8

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
Answer:
9.72 seconds
Step-by-step explanation:
9.72 seconds ( approx )
Step-by-step explanation:
Since, the equation that shows the height of the rocket from the ground,
Where,
x = time after launch, in seconds,
When the rocket hits the ground,
y = 0,
i.e.
By the quadratic formula,
∵ Time can not be negative,
So, the time taken to hit the ground = 9.716 seconds ≈ 9.72 seconds.
The time at which the rocket will hit the ground to the nearest hundredth of seconds is 15 seconds.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
As per the given height of tower y in terms of time is seconds x
y = -16x² + 240x + 115
The height of the tower when the rocket hit the ground will be zero.
Thus, y = 0
0 = -16x² + 240x + 115
16x² - 240x - 115=0
By quadratic equation formula,
x = [-(-240) ± √((-240)²+4×16×(-115))]/ 2×16
x = [240 ± 254.8725]/32
x = 15.46 and x = -0.46 since time can be never negative thus 15.46 seconds will be correct.
15.46 to the nearest hundred is 15.
Hence "The time at which the rocket will hit the ground to the nearest hundredth of seconds is 15 seconds".

Answer:
The values of x and y are x = 95 and y = 25
Step-by-step explanation:
If a quadrilateral is inscribed in a circle which means all its vertices lie on the circumference of the circle, then it is called a cyclic quadrilateral.
The properties of the cyclic quadrilateral
Every two opposite angles are supplementary (the sum of their measures is 180°)The measure of an exterior angle at one vertex equals the measure of the interior opposite angle to this vertexIn the given figure
∵ The four vertices of the quadrilateral QRTU lie on the circle
∴ QRTU is a cyclic quadrilateral
∵ ∠ PQU is an exterior angle of quadrilateral QRTU at Q
∵ ∠RTU is the opposite interior angle to it
→ By using the 2nd property above
∴ m∠PQU = m∠RTU
∵ m∠PQU = 95°
∵ m∠RTU = x°
∴ x = 95
∵ ∠QRT and ∠QUT are opposite angles in the cyclic quadrilateral
→ By using the 1st property above
∴ m∠QRT + m∠QUT = 180° ⇒ supplementary angles
∵ m∠QRT = 110°
∴ 110 + m∠QUT = 180°
→ Subtract 110 from both sides
∴ m∠QUT = 70°
In ΔSQU
∵ ∠ PQU is an exterior angle to the Δ T vertex Q
→ That means its measure equal the sum of the measures of the
two opposite interior angles QSU and QUS
∴ m∠PQU = m∠QSU + m∠QUS
∵ m∠PQU = 95°
∵ m∠QSU = y°
∵ m∠QUS = 70°
∴ 95 = y + 70
→ Subtract 70 from both sides
∴ 25 = y
∴ y = 25

what is the slope of the line (1/2,-4) (1/2,5)
Write the equation of a line that is perpendicular to y = 7/5x + 6 and that passes through the point (2,-6).
Answer:
y = -5/7x - 32/7
Step-by-step explanation:
Perpendicular slopes are "opposite reciprocals."
7/5 goes to 5/7, then -5/7 (if you don't get it you can comment)
So the perpendicular equation line: y = -5/7x + b (you don't know the y-intercept yet)
Substitute (2, -6) because that perpendicular line is going through it.
-6 = -5/7(2) + b
-6 = -10/7 + b
-42/7 = -10/7 + b
-32/7 = b
Perpendicular line equation: -5/7x -32/7

(b) About how many times larger was the population of the United States than the population of Columbus, Ohio?
Answer:
387.6. So, the closest whole number would be 388 times larger
Step-by-step explanation:
I divided the U.S. pop by the Columbus pop and got the answer: 387.6. So, the closest whole number would be 388 times larger
Answer:
The population of the United States is 387.87 times larger than the population of Columbus, Ohio.
Step-by-step explanation:
8.25 times 100000 = 825,000
3.2 times 100000000 = 320,000,000
320,000,000 divided by 825,000 = 387.87

Answer:
he worked 35 hours
equation: p= $9x + 250
p is pay
x is hours worked
Step-by-step explanation:
we know that the pay was 565 so plug that into p: 565= 9x + 250
subtract 250 from both side to isolate the variable: 315= 9x
divide both sides by 9: x= 35

m < 1 = 130°
m < 1 = 130°m < 2 = 50°
We know this is a linear pair, therefore the two angles must add up to 180°
[tex](m < 1 )+ (m < 2 )= 180[/tex]
[tex]5x + x + 24 = 180[/tex]
Combine like terms
[tex]6x + 24 = 180[/tex]
Isolate the variable
[tex]6x = 156[/tex]
[tex]x = 26[/tex]
Plug in 26 for x in both of the individual angle equations.
[tex]m < 1 = 5x[/tex]
[tex] = 5(26)[/tex]
[tex] = 130[/tex]
[tex]m < 2 = x - 24[/tex]
[tex] = (26) + 24[/tex]
[tex] = 50[/tex]
A good way to check if we did this correctly, is to add up the two angles. Because 180 + 50 = 180, we did this correctly.
I hope this helped. Let me know if you have any questions!
Use the figure to find measures of the numbered angles.
Answer:
1 = 137
2 = 43
3 = 43
4 = 137
Step-by-step explanation:
for the first line, do (180-137 = 43)
then, 43 would be corresponding angle to 2 - making them equal
2 would be vertically opposite to 3, making them equal
137 and 1 are corresponding- making them equal
4 is vertically opposite to 1 - making them equal
