Answer:
a=4
Step-by-step explanation:
combine like terms
8a-4=36
add on both sides
8a-4+4=36+4
8a=32
divide
a=32/8
a=4
Answer:
a = 5
Step-by-step explanation:
5a+3a = 8a
8a - 4 = 36
8a - 4 + 4 = 36 + 4
8a = 40
a = 40 divied by 8
a = 5

What is the equation of this line?
A.y=-2x
B.y=1/2x
C.y=1/2x
D.y=2x
Answer:
D. y = 2x
Step-by-step explanation:
The slope of the line is 2, so you get 2x. Therefore, the equation is y = 2x.
Answer:
the equation is answer D
Step-by-step explanation:
the slope is 2 and the y-intercept (b) is zero so it isn't written.

what is the solution to the original equations 8(3x-7) = -6(x+7)+4 ? Show your work
3/5
Step-by-step explanation:
8 (3x-7)=-6 (x+7)+4
24x-56=-6x+(-42)+4
24x+6x=-42+4+56
30x=-38+56
30x=18
30x/30=18/30
x=3/5

if one box has 8 books then n no.of boxes will have n × 8 no.of books
In 1846 the depth of the river was 5 feet deep. In 1847 it dropped to 3.2 feet. This year, 1848, it rose to 6.8 feet. Find the percent for EACH change in river depth
Answer:
1846= 0% change
1847= 3.2/5 ×100 = 64% decrease in river
1848= 6.8/3.2 ×100 = 212.5% increase
( used 3.2 because that was the last record)

Answer:
3(4/3)^2543
Step-by-step explanation:
Using logarithms base 2, we have ...
[tex](a_n)^{\log{a_n}}=(a_{n+1})^{\log{a_{n-1}}}\\\\(\log{a_n})(\log{a_n}) = (\log{a_{n-1}})(\log{a_{n+1}}) \\\\ \dfrac{\log{a_{n+1}}}{\log{a_{n}}}=\dfrac{\log{a_n}}{\log{a_{n-1}}}=\dots\dfrac{\log_2{16}}{\log_2{8}}=\dfrac{4}{3}[/tex]
That is, the ratio of each term to the previous is a constant equal to 4/3. This is the definition of a geometric sequence. This sequence has first term 3 and common ratio 4/3, so the general term is ...
[tex]\log_2 a_n=3\left(\dfrac{4}{3}\right)^{n-1}[/tex]
and the 2544th term is ...
[tex]\boxed{\log_2{a_{2544}}=3\left(\dfrac{4}{3}\right)^{2543}}[/tex]

The price of an item yesterday was $85. Today, the price rose to $136. Find the percentage increase
60%
Step-by-step explanation:
(136 - 85)/85 × 100%
= 51/85 × 100%
= 51/17 × 20%
= 3 × 20%
= 60%

Solve for d.
3 + d ≤ 3 - d
Answer:
[tex]3 + d \leqslant 3 - d \\ d + d \leqslant 3 - 3 \\ 2d \leqslant 0 \\ d \leqslant 0 \\ thank \: you[/tex]
1) Cancel 3 on both sides
d≤−d
2) Subtract -d from both sides.
d+d≤0
3) Simplify d+d to 2d.
2d≤0
4) Divide both sides by 2.
d≤0

Someone plz help URGENTLY will mark brainliest plz no links or will be reported
Step-by-step explanation:
Given the function, f(x) = -3x + 4, you basically need to choose any input (x-value) and substitute those values into the function.
f(0) = -3x + 4, where the input is x = 0.f(0) = -3(0) + 4
f(0) = 0 + 4
f(0) = 4 [this is the value of your final column, in the f(x)].
2. f( 1 ) = -3( 1 ) + 4, where the input is x = 1.
f( 1 ) = -3( 1 ) + 4
f( 1 ) = -3 + 4
f( 1 ) = 1 [this is the value of your final column, in the f(x)].
3. f(2) = -3(2) + 4, where the input is x = 2.
f(2) = -6 + 4
f(2) = -2 [this is the value of your final column, in the f(x)].
All you need to do is plot the following points on your graph:
{(0, 4), (1, 1), (2, -2)}

Write the algebraic expression into words 9m-3
Answer:
You probably already figured it out, but the correct answer is the last one. Subtract 3 from the product of 9 and m
Step-by-step explanation:
Reason for this is 9m is the same as 9 multiplied by m, or the product of 9 and m. You always do multiplication before subtracting or adding, therefore you are subtracting 3 FROM the product of 9 and m
