Answer:

34

Step-by-step explanation:

Since AD is a straight line the sum of ABC and DBC would be equal to 180°

2x + 4 + 3x + 6 = 180 add like terms

5x + 10 = 180 subtract 10 from both sides

5x = 170 divide both sides by 5

x = 34

What choices are solutions for equation x^2-3x = -5/4
Kryger [21]

Here's the solution,

=》

{x}^{2}  - 3x =  -  \dfrac{5}{4}

=》

{x}^{2}  - 3x +  \dfrac{5}{4}  = 0

now, let's multiply the whole equation with 4

=》

4 {x}^{2}  - 12x + 5 = 0

=》

4 {x}^{2}  - 10x - 2x + 5= 0

=》

2x(2x - 5) - 1(2x - 5) = 0

=》

(2x - 1)(2x - 5) = 0

so,

Case 1. where, 2x - 5 = 0

=》

x =  \dfrac{5}{2}

case 2. where, 2x - 1 = 0

=》

x =  \dfrac{1}{2}

What is the x-intercept of a line that passes through the point (3,4) and has a slope of 2?​
Blababa [14]

Answer:

(1,0)

Step-by-step explanation:

Hi there!

We want to find the x intercept of the line that passes through the point (3,4) and has a slope of 2

First, let's find the line

We are given both a slope, and a point. We can write the equation of the line in point-slope form, which is y-y_1=m(x-x_1), where m is the slope and (x_1, y_1) is a point

We do have everything needed to write the equation, let's just label everything to avoid confusion:

m=2

x_1=3

y_1=4

Now substitute those values as the variables that they represent into the equation:

y-y_1=m(x-x_1)

y-4=2(x-3)

Now we have the equation in slope-point form

The x intercept of the line is the value in which the line passes through the x axis. The value of y at this point is 0

So we can substitute y as 0 in the equation to find out the value of x:

y-4=2(x-3)

0-4=2(x-3)

Multiply

0-4=2x-6

Add 6 to both sides

0+2=2x

Simplify the left

2=2x

Divide both sides by 2

1=x

So the value of the x intercept is 1, also written as the point (1,0)

Hope this helps!
