Answer:

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Step-by-step explanation:

15x-(-3x-10)=38x-5(4x-2)
son4ous [18]
15x+3x+10 = 38x-20x+10
18x+10 = 18x+10
18x-18x = 10-10
0 = 0
The equation is true.

Enter a range of values for x please help me
Brums [2.3K]

Answer:

-5 < x < 9

Step-by-step explanation:

By Hinge theorem,

"If two sides of a triangle are congruent to the two sides of another triangle, and the included angle of one triangle is larger than the included angle of the second, then the 3rd side of triangle one will be larger than the third side of the second"

23 > 21

Therefore, 42° > (3x + 15)°

42° - 15° > 3x

27 > 3x

9 > x

And (3x + 15) > 0

3x > -15

x > -5

Therefore, range for x will be,

-5 < x < 9

The roots of 6 corn plants had depths of -3.54 feet? /2 4/5 feet, /3.86 feet, -3 2/5 feet. How many corn plants had roots betwee
Lana71 [14]

Since roots go down into the ground, the answers must be negative. That eliminates both 2 4/5 deep and 3.86. You could look at a number line if your unsure, but -3.54 is between 3 and 4, as is -3 2/5.

On average 83.1% of welds performed by a particular welder are defective. if, in one day, the welder creates three welds. what i
Nuetrik [128]
Let p be 0.831 denote the percentage of defective welds and q be 0.169 denote the percentage of non-defective welds.

Using the binomial distribution, we want all three to be defective.
P(X = 3) = \binom{3}{3}(p)^{3}{q}^{3 - 3}
P(X = 3) = \binom{3}{3}(0.831)^{3}(1)
P(X = 3) = (0.831)^{3} \approx 0.573856191

Write the equation of each line using the given information.
MrRissso [65]

Answer:

See explanation.

Step-by-step explanation:

We need a point and a slope to have a point slope equation.

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

We need a slope and y-intercept to write in slope intercept form.

y=mx+b

A) y-1=\frac{1}{2}(x+4) or y=\frac{1}{2}x+3

B) y+1=-1(x-2)

C) y-1=0(x-1)

D) y=-3x+8
