“ write the equation of the line that goes through the point (6,3) and is parallel to y=-2/3x+5 “ ????
brilliants [131]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - \frac{2}{3} x + 5 ← is in slope- intercept form

with slope m = - \frac{2}{3}

Parallel lines have equal slopes, thus

y = - \frac{2}{3} x + c ← is the partial equation of the line

To find c substitute (6, 3) into the partial equation

3 = - 4 + c ⇒ c = 3 + 4 = 7

y = - \frac{2}{3} x + 7 ← equation of line

Write 4x = 1024 in logarithmic form. A) logx1024 = 4 B) log41024 = x C) logx4 = 1024 D) log10241024 = x
Step2247 [10]
<span>The answer would be B) log4 1024 = x

The logarithmic form can be explained as

</span>log_{A}<span> B=C   -----> A^C=B

Using </span>A^C=B to the question (4^x=1024) will result
A=4
B=1024
C=x

If you put the variable into logarithmic form
log_{A} B=C
log_{4} 1024= x

1/4 miles to a shoe store. Then you walk another 2/5 miles to a music store. How many miles have you walked in all?
zavuch27 [327]

Answer:

\frac{13}{20}

Step-by-step explanation:

\frac{1}{4}  +  \frac{2}{5}

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.

\frac{ 1 \times 5}{4 \times 5}  +  \frac{2 \times 4}{5 \times 4}

\frac{5}{20}  +  \frac{8}{20}

=  \frac{13}{20}

demoninator now doesn't change unless you're multiplying or dividing.
