Answer: Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.
Here's how:
Step-by-step explanation:
19−4c=17
19 - 19 - 4c = 17 - 19 Subtract 19 from both sides 19-19 =0 Cancels on the left
-4c = 17-19 subtract: 17-19 = -2
-4c = -2
-4c/4 = -2/-4 Divide both sides by -4
Negatives divided by Negatives have a Positive quotient -4/-4 =1, Cancels
c = 1/2

Damarius is making some big life decisions! He decides it's time to start saving for his future and deposits $300 each month at 4.1% annual interest, compounded monthly, for 30 years. At the end of 30 years, he has an account balance of $211,966.64. How much of this did Damarius contribute and how much of this is interest?
Answer:
$108,000
$103,966.64
Step-by-step explanation:
Damarius contributes $300 each month, for 30 years. Therefore, to find the amount he contributed, we multiply those pieces together (12 months in each year).
300⋅12⋅30=$108,000
Therefore, over the 30 years, Damarius contributed $108,000.
If there was $211,966.64 in his account, and he contributed $108,000, then the rest is interest.
$211,966.64−$108,000=$103,966.64
There was $103,966.64 in interest earned on Damarius' account.

Which equation represents a line that passes through -2,4 and has a slope of 2/5 need help Now
Answer:
y = 2/5x + 24/5
Step-by-step explanation:
y - 4 = 2/5(x - (-2))
y - 4 = 2/5(x +2)
y - 4 = 2/5x + 4/5
y = 2/5x + 4/5 + 4
y = 2/5x + 24/5

What is the value of the expression below when z = 10 and w = 7
10z + 9w
Answer:
163
Step-by-step explanation:
10(10)+9(7)=
100+63=163
Answer:
163
Step-by-step explanation:
If z=10 and w=7.
10z+9w [writing the equation again for reference purposes]
10(10) + 9(7) [we substitute each variable with its defined value]
100 + 9(7) [we multiply 10 and 10, aka 10 and z]
100 + 63 [we multiple 9 and 7, aka 9 and w]
163 [we add 100 and 63 to get our final answer]
x^2-12x-6=-65 solve for x
Answer:
x
Step-by-step explanation:
x
Answer:
x = 6 + 4.796i and x = 6 - 4.796i
Step-by-step explanation:
For this problem, we will simply apply the quadratic formula to find the values of x. The quadratic formula is as follows:
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
Using the formula let's find the values of x.
x^2 - 12x - 6 = -65
x^2 - 12x - 6 + 65 = -65 + 65
x^2 - 12x + 59 = 0
The coefficient of x^2 is a, the coefficient of x is b, and the constant 59 is c.
Hence, for our formula we have the following values:
a = 1
b = -12
c = 59
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
x = [-(-12) +/- sqrt( (-12)^2 - 4(1)(59) ) ] / 2(1)
x = [ 12 +/- sqrt ( 144 - 236 ) ] / 2
x = [ 12 +/- sqrt ( -92 ) ] / 2
x = [ 12 +/- sqrt ( -4 * 23 ) ] / 2
x = [ 12 +/- 2i sqrt(23) ] / 2
x = 6 +/- i sqrt(23)
Hence from the formula, we have two possible values for x, both complex solutions. Note, i is an imaginary number.
x = 6 + i sqrt(23) and x = 6 - i sqrt(23)
x = 6 + 4.796i and x = 6 - 4.796i

Which relation is a function?
{(1, 2); (2, 3); (3, 4); (1, 5)}
{(1, 2); (1, 3); (3, 2); (4, 2)}
{(1, 2); (2, 5); (3, 2); (4, 5)}
{(1, 2); (2, 3); (3, 4); (2, 5)}
Answer:
the third relation: {(1, 2); (2, 5); (3, 2); (4, 5)}
Step-by-step explanation:
relations can only be a function if the input/x don't repeat at all.
its ok if the output/y repeat though!
{(1, 2); (2, 5); (3, 2); (4, 5)}, best represents the functions. Option C is correct.
Given that,
To determine which relation is a function.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Here,
For a relation to be a function, for two variables only one of the variables can have a repeated value i.e. dependent variable with respect to the others if the value of both variables is repeating then the relation is not a function. So,
{(1, 2); (2, 3); (3, 4); (1, 5)}
X repeated twice its not the function.
Similarly,
{(1, 2); (2, 3); (3, 4); (2, 5)} and {(1, 2); (1, 3); (3, 2); (4, 2)} are not the function.
But,
{(1, 2); (2, 5); (3, 2); (4, 5)} is function because the value of independent variable is not repeating.
Thus, {(1, 2); (2, 5); (3, 2); (4, 5)}, best represents the functions. Option C is correct.

What is the approximate volume of the cylinder? Round to the nearest hundredth. Use 3.14 for π.
1.05 cubic inches
1.57 cubic inches
3.14 cubic inches
6.28 cubic inches
Answer:
3.14, confirmed on Edge
Step-by-step explanation:
Since this cylinder has a radius of 1 inch, its volume is equal to 3.14 cubic inches.
Given the following data:
Radius of cylinder = 1 inch.
Height of can = 1 inch.
[tex]\pi =3.14[/tex]How to calculate the volume.Mathematically, the volume of a cylinder is given by this formula:
[tex]V = \pi r^2h[/tex]
Where:
h is the height.r is the radius.Substituting the given parameters into the formula, we have;

Diana baked 39 cookies with 3 scoops of flour. How many scoops of flour does Diana need in
order to bake 169 cookies? Solve using unit rates.
Answer:
Diana needs 13 scoops of flour to bake 169 cookies.
Step-by-step explanation:
well, first you need to find the unit rate.
if 3 scoops of flour makes 39 cookies,
then 1 scoop of flour makes 13 cookies. (39/3)
next, since the unit rate is 13 cookies per flour-scoop, divide 169 by 13 to get your answer.
169/13 = 13
Which of the following exponential equations shows a reflection over the y-axis, a vertical
stretch by a factor of 2, and horizontal shift right 1.
a. y = -2(4)* – 1
b. y = -2(4):-1
c. y = 2(4)-x-1
d. y = 4(2)-x-1
Answer:
we are given
parent function as
(1)
vertical stretch of factor 2
so, we can multiply y-value by 2
then a shift right of 3 units
so, we can replace x as x-3
(2)
a shift left by 2 units
we can replace x as x+2
then a horizontal shrink factor of 1/2
so, we can multiply by 2 to x-value
then a shift down of 5 units
we can subtract y-value by 5
so, we get
(3)
a shift to the right 1 unit
we can replace x as x-1
stretched vertically by a factor of 1/2
we can multiply y-value by 1/2
then is shifted down 4 units
we can subtract y-value by 4
(4)
reflected across the x-axis
we can multiply y-value by -1
tretched vertically by a factor of 3
multiply y-value by 3
shifted left 7 units
we can replace x as x+7
