Yes so first the ratio is 3 (30/10)

so then you take the original ratio (9/10) and multiply the 9 by 3 (27)

30+27=57 so yes it is

GOD PLZ HELP:: Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes.

Annette [7]

Answer:

x intercept is (3.75, 0) and y intercept is (0, 2.5)

Step-by-step explanation:

4x + 6y - 15 = 0

x int = (3.75, 0)

0*6 = 0

4x - 15 = 0

0 + 15 = 4x = 15

15/4 = 4x

x = 3 3/4 or 3.75

y int = (0, 2.5)

0*4 = 0

6y - 15 = 0

15 = 6y

15/6 = y

y = 2.5

Answer:

$x = \sqrt{\frac{7}{2} }$

Step-by-step explanation:

<u><em>Explanation</em></u>

From given graph

AC = √7

Given angle ∝ = 45°

$cos\alpha = \frac{adjacentside}{Opposite side}$

$cos45 = \frac{x}{\sqrt{7} }$

$\frac{1}{\sqrt{2} } = \frac{x}{\sqrt{7} }$

$x = \frac{\sqrt{7} }{\sqrt{2} }$

$x = \sqrt{\frac{7}{2} }$

x = 1.8708

How do I solves these problems

1) 2z= -6
divide both sides by 2
2z/2= -6/2
2 on the left cancels out
z= -3

2) y/-5= 20
multiply both sides by -5
(-5)(y/-5)= (-5)(20)
-5 on the left cancels out
y= -100

Hope this helps! :)
