5x+15 = 6x-10

Subtract 5x from 6x which leaves you with 15 = x-10

Now you add 10 to both sides of the equal sign. 25 =          

x=25

Answer:

Option B k > 0

Step-by-step explanation:

we know that

Observing the graph

The slope of the line is positive

The y-intercept is negative

we have

3y-2x=k(5x-4)+6\\ \\3y=5kx-4k+6+2x\\ \\3y=[5k+2]x+(6-4k)\\ \\y=\frac{1}{3}[5k+2]x+(2-\frac{4}{3}k)

The slope of the line is equal to

m=\frac{1}{3}[5k+2]

Remember that the slope must be positive

so

5k+2> 0\\ \\k > -\frac{2}{5}

The value of k is greater than -2/5

Analyze the y-intercept

(2-\frac{4}{3}k) < 0\\ \\ 2 < \frac{4}{3}k\\ \\1.5 < k\\ \\k > 1.5

1.5 is greater than zero

so

the solution for k is the interval ------> (1.5,∞)

therefore

must be true

k > 0

In the triangle below, 21 = 35 and 3 = 100
vesna_86 [32]

Answer:

135

Step-by-step explanation:

Okay so we know that all angles in  tringle sums up to 180

Therefore ∠2 = 180 - ∠1 - ∠3 = 180 - 35 - 100 = 45deg

We also know that angles on a straight line add up to 180deg as well

Therefore ∠4 = 180 - ∠2 = 180 - 45 = 135deg

What is the equation of the following line written in slope-intercept form -2/3 and -1/-4? y = -11x - 7 y = -7x + 11 y = -7x - 1
Snowcat [4.5K]

Answer:

y=-7x-11

Step-by-step explanation:

Given:

The two points on the line are (-2,3) and (-1,-4).

The slope of the line joining two points (x_{1},y_{1}) and (x_{2},y_{2}) is given as:

Slope,m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Here, x_{1}=-2,y_{1}=3,x_{2}=-1,y_{2}=-4

∴ m=\frac{-3-4}{-1-(-2)}=\frac{-7}{-1+2}=\frac{-7}{1}=-7

Equation of line with a point (x_{1},y_{1}) and slope m is given as:

y-y_{1}=m(x-x_{1})

Plug in -2 for x_{1}, 3 for y_{1} and -7 for m. This gives,

y-3=-7(x-(-2))\\y-3=-7(x+2)\\y-3=-7x-(7\times 2)\\y-3=-7x-14\\y=-7x-14+3\\y=-7x-11

Therefore, the equation of the line in vertex form is y=-7x-11.
