Y intercept is where our x variable is equal to 0 and where the graph touches the y-axis.

Therefore, you can get the y intercept by just plugging in x = 0. For example, in the linear function: f(x) = 2x + 3, our y intercept would be (0,3) because we just set our x value equal to 0.

Answer:

x = -0.17 and x = -5.83

Step-by-step explanation:

We are asked to solve the quadratic equation

$x^2+6\,x+1=0$

We use the quadratic formula using a = 1, b = 6 and c = 1

for a general quadratic equation of the form: $ax^2+bx+c=0$

Then, the solutions are given by;

$x=\frac{-6+/-\sqrt{36-4\,(1)\,(1)} }{2} =\frac{-6+/-\sqrt{32} }{2}$

which produces the two following answers (rounded to two decimals):

x = -0.17 and x = -5.83

Make U the subject of the formula <br> D = ut + kt2

natali 33 [55]

Remark

I'm going to interpret this equation as

D = ut + kt² The only difference is the 2.

Solution

Subtract kt² from both sides.

D - kt² = ut Now divide by u on both sides.

$\dfrac{D - kt^2}{t} = \dfrac{ut}{t}$

The t's cancel out. on the right. You are left with u on the right.

$\dfrac{D - kt^2}{t} =\text{u}$

P = a^b + b^a. Given a,b,p are prime numbers. find the value of p

VARVARA [1.3K]

2³ + 3² = 2*2*2+3*3= 8+9=17
a=2,
b=3,
P= 17,
2,3,17 are all prime numbers

Is my answer A or d??

alexira [117]

Answer:

Step-by-step explanation:

The answer must have a negative slope because the graph is decreasing.

The y-intercept is 10. The equation must have +10 at the end.

y = -3x + 10
