Answer:

C) y = 2x +8

Equation of the straight line passing through the point (-2,4) and having slope m =2

y = 2x +8

Step-by-step explanation:

Step(i):-

Given that the points are (-2,4) and (6,20)

The slope of the line

   m =   [tex]\frac{20-4}{6-(-2)} = \frac{16}{8} =2[/tex]

    m =2

Step(ii):-

Equation of the straight line passing through the point (-2,4) and having slope m =2

y - 4 = 2( x-(-2))

  y = 4 + 2x  +4

 y = 2x +8

Answer:

Step-by-step explanation:

length = 5 m

height = 1.8 m

The triangle that it formed is given in the figure,

Now first we have to find angle A,

sin(A) =perp/hyp = 1.3/5 = 0.26

now we get ,

Angle A = 15 degree

now using ,

tan(15) = perp/base = 1.3/distance

distance = 1.3/tan(15)

distance =1.3/0.27

distance = 4.8 m

Step-by-step explanation:

1) 10 * 10 * 10 = 1000

2) 10 * 10 is not = to 1000

3) 10^2 is not = to 1000

4) 10^3 = 1000

5) simplify it is 150

6) simplify it is not 1500

Answer:

The answer is 7 because if we write 7 - 8 = -1, then we could see that the answer would be -1 since 7 is 1 value lower than 8, and 8 - 8 = 0, so if 7 is lower than 8 by 1, then you would go one value lower from 0, which is -1. You can also figure this out by looking at a number line and starting from 7 and then going backwards 8 times and whatever number you land on after going back 8 times is your answer.

The number factor of a variable term is called the numerical coefficient.

Algebraic expression are made of terms . Terms might be a signed numbers, a variable, or a constant multiplied by a variable or variables.

Examples of an algebraic expression is as follows:

When a constant is multiplied by a variable or variables , that constant is called the coefficient.

In our example the variable is x . The number factor of the variable term x is called the numerical coefficient .

Therefore, the numerical coefficient in our case is 4.

Answer:

y=17/3x-26

Step-by-step explanation:

So what you need to do is find the slope and y-intercept. Then, you write it in y=mx+b form. m=slope, b=y-intercept. So in this case, 17/3 is the slope, and -26 is the y-intercept. Hope this helps :)

Answer:

No solution

Step-by-step explanation:

Use the quadratic formula

Simplify

No real solutions because the discriminant is negative

Answer:

slope = [tex]-\frac{4}{3}[/tex]  

Step-by-step explanation:

Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. [tex]m[/tex] represents the slope. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (-3, 4) and (0, 0) into the formula appropriately and solve:

[tex]m= \frac{(0)-(4)}{(0)-(-3)} \\m = \frac{0-4}{0+3} \\m = \frac{-4}{3}[/tex]

Thus, the slope is [tex]-\frac{4}{3}[/tex].
