Answer:
b=4
Step-by-step explanation:
-11+9b^2=25
add 11 to both sides
9b^2=36
divide both sides by 9
b^2=4
take the square root of both sides
b=4
Answer:
the second day
Step-by-step explanation:
4(d + 2) - 2d = 3(2 + d)
4d + 8 -2d = 6 + 3d
2d + 8 = 3d + 6
-6 -6
2d + 2 = 3d
-2d -2d
2 = d
to check your answer:
4(2 + 2) - 2(2) = 3(2 + 2)
4(4) - 4 = 3(4)
16 - 4 = 12
12 = 12
I’m assuming you mean plus so it would be 7 cm if you mean multiplication then still 6 cm
The equation of the line through (3,-5) and perpendicular to -3x + 2y = 12 in slope-intercept form is y = -2/3x + 1
<h3>Equation of a line</h3>
The equation of a line is expressed as;
y = mx + b
m is the slope
b is the y-intercept
Given the equation -3x + 2y = 12
2y = 3x + 12
y = 3/2x + 6
From the equation, the slope that is perpendicular to the slope is -2/3
<u>Determine the equation</u>
y-(-5) = -2/3(x-3)
y+5 = -2/3x + 6
y = -2/3x + 6 - 5
y = -2/3x + 1
Hence the equation of the line through (3,-5) and perpendicular to -3x + 2y = 12 in slope-intercept form is y = -2/3x + 1
