Answer:
only the 3rd one and 2nd shows correct comparison
Answer:
<em>In Explanation</em>
Step-by-step explanation:
First, you should put the equation in slope intercept form (y = mx + b), where m is the slope.
10x + 4y = 20
Isolate the y term
10x + 4y – 10x = 20 – 10x
4y = 20 – 10x
Rearrange the terms
4y = –10x + 20
Divide both sides by 4
4y4=−10x+204
y=−104x+5
The slope of the given line is –10/4. A perpendicular line will have a slope with the opposite reciprocal. In simpler terms, you flip the slope and change the sign, therefore, the opposite reciprocal is 4/10.
So we say x=-2
so in the equation where ever we see x we plug in like
f(-2)= 2 * (-3)^3 + 3 * (-2)^2
= 2 * -8+ 3 * 4
= -4
(-2,-4)
hope that helps
Answer:
The roots of any quadratic equation is given by using: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the shape of ax^2 + bx + c = zero. If the equation is in the shape y = ax^2 + bx +c, honestly replace the y with zero. that is achieved because the roots of the equation are the values where the y axis is same to 0.
Answer:x = 9.01
Step-by-step explanation:
The given triangle is a right angle triangle.
From the given right angle triangle the hypotenuse of the right angle triangle is 17
With 35 degrees as the reference angle,
x represents the adjacent side of the right angle triangle.
The unlabelled side represents the opposite side of the right angle triangle.
θ = 35 degrees
To determine x, we would apply trigonometric ratio
Cos θ = adjacent side/hypotenuse side. Therefore,
Cos 35 = x/11
x = 11 Cos 35 = 11 × 0.8192
x = 9.01
