If an angle measures 90 then, it is a right angle. 2.if it is a right angle then, the angle measures 90. I dont know the last two.

write the slope intercept form of an equation of the line that passes through (4,3) that is perpendicular to the line Y=-3x-15

cricket20 [7]

If two lines are perpendicular, then their slopes have a product of -1 or you could say they are opposite signed reciprocals of each other.
The given equation has a slope of -3. We know this because it is in slope-intercept form y = mx + b ...y = (slope)x + (y-intercept).

so taking the slope -3...the opposite signed reciprocal would be + $\frac{1}{3}$

Now we have a slope and a point... we can use them to find the b (y-intercept)
x = 4, y = 3, and m = $\frac{1}{3}$
$3= \frac{1}{3} (4)+b$
$3= \frac{4}{3} +b$
Using the common denominator fraction for 3, we subtract 4/3 from both sides
$3= \frac{9}{3}$
$\frac{5}{3} =b$
plug the values for m and b into the slope intercept form
$y= \frac{1}{3} x+ \frac{5}{3}$

Find the length of the missing side (nearest tenth). 25 yd 37 yd

Ket [755]

Answer:

27.3 yards

Step-by-step explanation:

Since this triangle is a right triangle, this can be solved using the equation:

a^2 + b^2 = c^2

c^2 is the side opposite to the right angle (37)

So, you need to change the equation to where it is set equal to b^2.

Subtract a^2 on both sides.

b^2 = c^2 - a^2

Now, plug in the numbers you have.

b^2 = 37^2 - 25^2

Simplify.

b^2 = 1369 - 625

b^2 = 744

Now, to find b, take the square root of 744.

√744 = 27.3

Solve for w: -5(3-w)+4=-5/6(24-6w)

AfilCa [17]

Answer:

no solution

Step-by-step explanation:

well first you gotta distribute

-5(-3 - w) + 4 = -5/6(24 - 6w)

15 + 5w + 4 = -20 + 5w

19 + 5w = -20 + 5w

+20 +20

39 + 5w = 5w

-5w -5w

39 ≠ 0

therefore there is no solution (which is the answer)

Which scenarios have a posItive correlation. MARK ALL THAT APPLY. *

Anit [1.1K]

Answer:

Step-by-step explanation:

well the negative correlations are the number of calories consumed and the amount of weight lost by a person and the thickness of the ice on a lake and the likelihood of falling through the ice.

Negative correlation is defined as an inverse relationship between two entities. If entity 1 increases, entity 2 decreases and if entity 2 increases, then entity 1 decreases.

So the postive are

the temperature outside and the number of pool guests

the number of children assigned to a class and the number of desks

the price of apples and the number of giraffes in Africa
