Write an equation in slope-intercept form for a line that passes through the given pair of points. (-6,5), (-9,0)

1 answer:

4 0

Slope intercept form is y=mx+b because m=slope and b=y-intercept hence "slope intercept form"...

m=deltay/deltax=(0-5)/(-9--6)=-5/-3=5/3 so far we have now:

y=5x/3 +b, using any point, I'll use (-9,0) we can now solve for b or the y-intercept...

0=-9(5)/3 +b

0=-15+b, so b=15 and our line is:

y=5x/3 + 15 or more neatly

y=(5x+45)/3

Which of the following investments could be represented by the function A = 250(1 + 0.08/12)12 × 4?

Alekssandra [29.7K]

hello,

the first term is 250 so this is the initial invested amount

$(1+\dfrac{0.08}{12})^{12}=(1+\dfrac{8\%}{12})^{12}$

is to compute 8% annual interest compounded monthly (there are 12 months in a year)

and then multiply by 4 means that it is computed for 4 years so

finally the answer is

$250 is invested at 8% annual interest compounded monthly for 4 years

hope this helps

WWhat is the solution to the equation 1/2 X +3 equals 2/3 X plus one

RUDIKE [14]

1/2x + 3 = 2/3x + 1....multiply everything by the common denominator of 6
3x + 18 = 4x + 6
3x - 4x = 6 - 18
-x = - 12
x = 12 <====

multiplying by the common denominator will get rid of the fractions

Answer:

Step-by-step explanation:

To get the other angles you need to do this

110+80+x+x=360

190+2x=360

2x=360-190

2x=170

X=170÷2

X=85
