y = -3/2 x + 4

Step-by-step explanation:

y - y1 = m(x - x1)

Here, m = slope = -3/2 & (x1,x2) = (2, 1)

=> y - 1 = (-3/2) (x - 2)

=> y - 1 = -3/2 x + 3

=> y = - 3/2 x + 3 + 1

=> y = -3/2 x + 4

What is the x-and y-intercept of the graph 4x -5y =40??
umka21 [38]

Answer:

x-intercept = 10

y-intercept = -8

Step-by-step explanation:

4x-5y=40

To identify the y-intercept, we will need to format the equation in the form y=mx+b. We can start by subtracting 4x from both sides of the equation:

-5y=-4x+40

Divide both sides of the equation by the coefficient of y, which is -5:

y=\frac{-4}{-5} x - 8

The b is representative of the y-intercept in y=mx+b.

Identify b in the equation y=\frac{-4}{-5} x - 8:

b=-8

Therefore, our y-intercept is -8.

To solve for the x-intercept, replace the y in the equation y=\frac{-4}{-5} x - 8 with a zero:

0=\frac{-4}{-5} x - 8

Add 8 to both sides of the equation:

8=\frac{-4}{-5} x

You can go ahead and divide -4 by -5 to get rid of the fraction:

8=0.8x

Divide both sides of the equation by the coefficient of x, which is 0.8:

10=x

Therefore, our x-intercept is 10.

The diameter of a circle has endpoints whosever coordinates are R(-2,2) and S(4,2). find the center of the circle
lisov135 [29]
Hello!

As you can see this line is horizontal. It is 6 units long. Therefore the center is three units in. Therefore the center of this circle is at (1,2).

I hope this helps!

6+(-9)= I want a answer<br>​
choli [55]
It would be -3. since they’re different signs you would subtract instead of doing addition. you also would us the greater numbers sign, which, in this case, -9 is the greater number so the answers sign would be negative.

HI yeah its me again
damaskus [11]

Answer:

4\sqrt[3]{7x}

Step-by-step explanation:

Look for the same stuff under the radical symbol. Here, that "stuff" is "7x". Only one answer choice has 7x under the radical.

_____

Here, there are no cubic factors under the radical that can be factored out—either in the problem expression or in the answer choices. If there were cubic factors, you'd want to remove them before making the comparison.

For example, ∛(56x) would be a like radical to ∛(7x) because a cubic factor of 2^3 = 8 can be removed to make it be 2∛(7x).

#4 need help with this one
4vir4ik [10]

Answer:

x = 25.6

Step-by-step explanation:

As we can see, this is a right triangle, so there are known relationships

well to start we have to know the relationship between angles, legs and the hypotenuse

α = 43

a: adjacent  = x

o: opposite

h: hypotenuse  = 35

sin α = o/h

cos α = a/h

tan α = o/a

we see that it has (angle, adjacent, hypotenuse)

cos α = a/h

cos 43° = x / 35

cos 43° * 35 = x

25.59 = x

if we want to round to the nearest tenth

x = 25.59 = 25.6
