Find the x and y intercepts using the standard form equation of: y-1/4x = -1/2

mojhsa [17]

The x intercept is when the line passes through the x axis , the only time that happens is when y=0
the y intercept is when the line passes through the y axis, the only time that happens is when x=0

so to solve for them, set the other coortinate to zero so
x intercept is when y=0 so set y to zero and solve for x
0-1/4x=-1/2
-1/4x=-1/2
multiply both sides by -4/1
x=2
the x intercept is (2,0)

the y intercept is when x=0 so set x to zero
y-1/4(0)=-1/2
y=-1/2
the y intercept is (0,-1/2)

the x itnercept=(2,0)
the y intercept=(0,-1/2)

Saj makes Rose Pink paint and Cherry Pink paint. He mixes red paint with white paint as shown. Rose Pink red : white =1:2 Cherry

Julli [10]

Answer:

No. He had not made cherry pink paint

Step-by-step explanation:

Rose Pink red : white = 1 : 2

Cherry Pink red : white = 4 : 3

...he adds 80 litres of red paint and 28 litres of white paint.

The question basically want us to check if it follows the ratio.

To have the cherry pink, the ratio must be 4:3 however the ration of paint he mixed is;

80 : 28 which is equivalent to 20 : 7

This means he had not made cherry pink paint

If √6 is the geometric mean between 4 and another number, then the number is 1.5 9 24

konstantin123 [22]

Correct answer is A.

g - geometric mean
$g= \sqrt{ab} 
\\
\\g= \sqrt{6} ,a=4,b=?
\\ \sqrt{6}= \sqrt{4b} 
\\ (\sqrt{6})^2= (\sqrt{4b} )^2
\\6=4b
\\
\\b= \frac{6}{4} = \frac{3}{2}=1.5$
