Answer:
b= 4a-c
Step-by-step explanation:
There isnt an actual number you can solve for here so just say what b equals to.
4a-b=c
Move b
4a=b+c
Move C

If f(1)=7f(1)=7 and f(n)=f(n-1)+2f(n)=f(n−1)+2 then find the value of f(4)f(4).
Answer:
Step-by-step explanation: f1 =7
f2 = 5(7) + 2 = 37
f3 = 5(37) + 2 = 27
f4 = 5(9) + 2 = 47____
The value of f(4)f(4) f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2 is,
121.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2.
By this pattern,
f(4)f(4) = [f(4 - 1) + 2f(4)][f(4 - 1) + 2f(4)].
f(4)f(4) = [f(3) + 2f(4)][f(3) + 2f(4)].
f(4)f(4) = [f(3) + 2(4)][f(3) + 2(4)].
f(4)f(4) = [3 + 8][3 + 8].
f(4)f(4) = [11][11].
f(4)f(4) = 121.

A chemical company makes up batches of copper sulfate solution by adding 250 kg of copper sulfate powder to 1000 liters of water. A laboratory chemist wants to make a solution of identical concentration, but only needs 350 mL (0.35 liters) of solution.
How much copper sulfate powder should the chemist add to the water? Enter your answer in the box below in decimal format.
The mass of copper sulfate that the chemist should add is______
kg.
help me please
Answer:
0.07 kgStep-by-step explanation:
Assuming copper sulfate has same density as waterChemical to water ratio as per given is:
250 kg : 1000 liter = 1 kg : 4 literLab solution is 350 ml
Converting to same ratio as above:
350/(1 + 4) = 70 ml
70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 mlAnswer is 0.07 kg

Mario got a part time job mowing lawns. On Monday he charged his neighbor $25 to mow his lawn, then spent $6 to refill his lawn mower with gas. The next day he mowed his Grandparents yard for $20. How much money does Mario have after mowing both yards?
Answer:
$39Step-by-step explanation:
Step one:
He charged $25 and spent $6 on gas on Monday.
then he made 25-6= $19 mowing his neighbor's lawn.
the next day is Tuesday(we are not told he spent any amount on gas on Tuesday).
So he mowed his Grandparents yard for $20.
total money saved for Monday and Tuesday is
19+20= $39
Hence he has $39 for mowing both yards

write an equation in slope intercept form that passes through the points (-4,3) and (0,2)
Answer:
[tex]y = -\frac{1}{4}x +2[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx + b
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Given points: (-4, 3), (0, 2)
(0, 2) = (x1, y1)
(-4, 3) = (x2, y2)
To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.
First, let's find the slope. To do this, input the given points into the formula used to find slope:
[tex]\frac{3-2}{-4-0}[/tex]
Simplify:
3 - 2 = 1
-4 - 0 = -4
[tex]\frac{1}{-4}= -\frac{1}{4}[/tex]
The slope is [tex]-\frac{1}{4}[/tex].
To find the y-intercept, input the slope and one of the given points(in this example I'll use point (0, 2)) into the equation and solve for b:
[tex]2 = -\frac{1}{4} (0)+b[/tex]
2 = 0 + b
2 = b
The y-intercept is 2.
Now that we know the slope and the y-intercept, we can write the equation:
[tex]y = -\frac{1}{4}x +2[/tex]

Find the value of c that completes the square
x^2-16x+c
Please help me with how to do this, and show me. Thank you.
Answer:
c = 64
Step-by-step explanation:
Given
x² - 16x + c
To complete the square
add ( half the coefficient of the x- term )² to x² - 16x
x² + 2(- 8)x + 64
= (x - 8)²
Thus
x² - 16x + 64 = (x - 8)² ← a perfect square
with c = 64

Explain why 173 degrees cannot be an interior angle from any regular polygon.
173 cannot be an interior angle of any regular polygon because the number of sides would be negative.
Why can't the interior angle of the polygon be 173 degrees?
The formula that can be used to determine one of the one interior angle of an n-sided polygon is [180(n−2)]/n .
In order to determine the value of n, take the following steps:
[180(n - 2) ]/ n = 173
Multiply both sides of the equation by n
180(n - 2) = 173n
Divide both sides by 180
n - 2 = 0.961111n
Combine similar terms
n - 0.96n = 2
0.038889n = 2
n = 51.4
