through: -1,4 and 0,0 point slope
Step-by-step explanation:
the slope = (4-0)/(-1-0) = 4/(-1) = -4
the equation : y = -4x
m = (Y2 - Y1)/(X2 - X1)
m = (0 - 4)/(0 - (-1))
m = -4/(0 + 1)
m = -4/1 = -4
Complete the equation of the line through (−10,3) and (-8,-8)
Answer:
[tex]\boxed{y = -5,5x - 52}[/tex]
Step-by-step explanation:
Equation of a straight line: y = kx + b
Points: (-10,3) and (-8,-8)
Сompose the system of equations:
[tex]\displaystyle \left \{ {{3=-10k + b} \atop {-8=-8k + b}} \right[/tex] [tex]\displaystyle \left \{ {{b= 3 + 10k} \atop {b=8k - 8}} \right \Longrightarrow 3 + 10k = 8k - 8[/tex]
[tex]3 + 10k = 8k - 8[/tex]
[tex]2k = -11|:2[/tex]
[tex]k = -5,5[/tex]
[tex]b = 3 + 10k = 3 + 10 \cdot ( -5,5) = 3 - 55 = -52[/tex]

Answer:
x = 47
Step-by-step explanation:
Because the lines are parallel, we know that some angles are the same, see the images attached. That means that A and B in the image are the same angles. So we know that angle A totals to 78 degrees. And the angle outside the triangle is 35. So the angle inside the triangle is
78 - 35 = 43.
The interior angles of a triangle add up to 180. We know that one angle is 43 and another angle is 90 because of the indicating square angle marker. That means that
43 + 90 + x = 180.
Then we can simplify the equation:
133 + x = 180⇒
x = 180 - 133⇒
x = 47

Find the slope and y-intercept
Answer:
slope = 35/2
y intercept is 0
Step-by-step explanation:
the y-intercept is 0 because you can see from the graph that it intersect with y-axis at (0,0)
Slope = rise /run
pick a point (8, 140)
rise = 140
run = 8
slope = 140/8 = 70/4 = 35/2

Answer: C
Step-by-step explanation: using Δx/Δy we find that the slope is -59. Since the y intercept is -176 using the plug in -235 = -59(1) + b, C is the only one that can match that answer.

x^2+18=0 solve please
9514 1404 393
Answer:
x = ±3√2i
Step-by-step explanation:
Add -18 to both sides of the equation:
x^2 = -18
Take the square root of both sides:
x = ±√(-18)
Remember that 18=9·2 = (3^2)·2 and √-1 = i. Simplify.
x = ±(√(3^2))·(√2)·(√-1)
x = ±3√2i
What is the equation of the line that passes through the point (1,3)and has a slope of 6
Answer:
y = 6x - 3
Step-by-step explanation:
y = mx + B
3 = 6(1) + B
3 = 6 + b
3 - 6 = b
-3 = b
b = -3
3 = 6(1) - 3
3 = 3
y = 6x - 3

Use factoring to solve the quadratic equation. Please provide an explanation.
x^2-25=0
Answer:
±5
Step-by-step explanation:
Given equation ,
=> x² - 25 = 0
=> x² - 5² = 0
=> ( x +5)(x-5) = 0
=> x = ±5
Answer:
x = -5 or 5
Step-by-step explanation:
→ Factor the quadratic
( x + 5 ) ( x - 5 )
→ Equate each bracket to 0
x + 5 = 0 and x - 5 = 0
→ Solve each for x
x = -5 or 5

What is the solution to the equation 5x+1.2=−3.8, given the replacement set {−1, −0.52, 1} ?
Answer:
the answer is x=-1
Step-by-step explanation:
The required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question below as:
5x + 1.2 = −3.8
We have to determine the solution to the given equation 5x + 1.2 = −3.8
⇒ 5x + 1.2 = −3.8
Rearrange the terms of non-variable in the above equation,
⇒ 5x = - 3.8 - 1.2
Apply the addition operation,
⇒ 5x = -5
Divided by 5 both sides of the above equation,
⇒ x = -5 / 5
Apply the division operation,
⇒ x = - 1
Therefore, the required solution to the given equation 5x + 1.2 = −3.8 is x = - 1.
