YES if you simplify 15:10 by 5 since they can both be divided by 5 the ratio becomes 3:2
6b^2-5b=4
6b^2-5b-4=0
6b^2+3b-8b-4=0
(6b^2+3b) (-8b-4)
3b(2b+1) -4(2b-1)
(3b-4) (2b-1)
hope i helped
Answer:
<h3> y= -3/4x - 4</h3>
Step-by-step explanation:
To write an equation that is perpendicular to a given line, take the negative reciprocal of the given slope. the given slope is 4/3, so the negative reciprocal is -3/4.
Using slope-intercept form of a linear equation, y=mx+b substitute in -3/4 for "m" the slope.
y=-3/4x+b
Now you need to "b" the y-intercept using the given point (-4,-1). Substitute the values in the equation. -1=-3/4(-4)+b simplify
-1= 3 + b subtract 3 for both sides
-4=b
substitue -4 for b. Now you have y= -3/4x - 4 this is your answer.
Answer:
45 dimes
Step-by-step explanation:
66 nickels = 66 x $0.5 = $3.30
$7.80 - $3.30 = $4.50
$4.50 / $0.10 = 45
