Step-by-step explanation:
The drink you usually buy is on sale, the price has been reduced by $2 per can, this means you can get 28 cans for the same price that you usually pay for 20 cans, determine the original price
Answer:
The answer is $2.80.
Step-by-step explanation:
The price was reduced to two dollars and you buy 28 cans for the same price in which you got 20 cans at original price. So you need to take 28 cans times 2, which you will receive 56. Take 56 the price divided by 20 the original price cans and you will receive 2.8 or $2.80. To double check your work, take 2.80 times 20 and see if you get 56. #BallersKnowMath

Answer:
X=5
Step-by-step explanation:
f(1)= -1^2+4(1)+12=15
f(2)= -2^2+4(2)+12=16
f(3)= -3^2+4(3)+12=15
f(4)= -4^2+4(4)+12=12
f(5)= -5^2+4(5)+12=7
g(1)=1+2=3
g(2)=2+2=4
g(3)=3+2=5
g(4)=4+2=6
g(5)=5+2=7
so g(5)=f(5)= X=5
Answer:
Step-by-step explanation:
You're suppose to plug in the values 1, 2, 3, 4, 5, and 6 into f(x) and g(x) to find where they're equal to find the solution to f(x) = g(x) (when the column values are equal).
So for example
f(1) = -(1)^2 + 4(1) + 12
f(1) = -1 + 4 + 12
f(1) = 15
g(1) = 1 + 2
g(1) = 3
put these two values in the table for f(1) and g(1)
f(2) = -(2)^2 + 4(2) + 12
f(2) = -4 + 8 + 12
f(2) = 16
g(2) = 2 + 2
g(2) = 4
f(3) = -(3)^2 + 4(3) + 12
f(3) = -9 + 12 + 12
f(3) = 15
g(3) = 3 + 2
g(3) = 5
f(4) = -(4)^2 + 4(4) + 12
f(4) = -16 + 16 + 12
f(4) = 12
g(4) = 4 + 2
g(4) = 6
f(5) = -(5)^2 + 4(5) + 12
f(5) = -25 + 20 + 12
f(5) = 7
g(5) = 5 + 2
g(5) = 7
f(5) = g(5) so the solution is when x=5
f(6) = -(6)^2 + 4(6) + 12
f(6) = -36 + 24 + 12
f(6) = 0
g(6) = 6 + 2
g(6) = 8
Find the equation of a line that passes through the point (-2,1) and has a gradient of -3.
Leave your answer in the form
y
=

x
+
c
A straight line passing through the point (-2,1) and having a gradient of -3 yields the equation y = -3x - 5.
We know that a straight line is an infinitely long line with no curves on it. A straight line's equation is
y = mx + c...(1), where m is the gradient of the straight line and c is a constant.
Given that the gradient of the given straight line = m = -3.
Putting this value in (1), we get
y = -3x + c ...(2)
Again, the given straight line passes through the point (-2,1). So, we can put x = -2 and y = 1 to get the value of the constant c.
So, 1 = (-3)(-2) + c
i.e. 6 + c = 1
i.e. c = 1 - 6 = -5
(2) can be written as
y = -3x - 5
Therefore the equation of the given straight line is
y = -3x - 5

Find the monthly house payment necessary to amortize the following loan. In order to purchase a home, a family borrows $110,000 at 2.9% for 30 yrs. What is their monthly payment? Round the answer to the nearest cent.
The monthly payment for purchasing the home will be $457.85.
What is a monthly payment?The term loan refers to a sort of credit vehicle in which a sum of money is lent to another party in exchange for the value or principal amount being repaid in the future.
Then the formula of monthly payment (MP) will be
[tex]\rm MP = P \times \dfrac{r(1+r)^n}{(1+r)^n - 1}\\[/tex]
In order to purchase a home, a family borrows $110,000 at 2.9% for 30 years.
We have
P = $110,000
r = 0.029 / 12 = 0.0024
n = 30 × 12 = 360
Then the monthly payment will be
[tex]\rm MP = 110,000\times \dfrac{0.0024(1+0.0024)^{360}}{(1+0.0024)^{360} - 1}\\\\[/tex]

The question is incomplete. Below you will find the missing content in the figure.
Prove: m/EIF = m/GIH
Step Reason
m∠EIF+m∠FIG = 180°
m∠FIG+m∠GIH= 180°
m∠EIF+m∠FIG= m∠FIG+m∠GIH
m∠EIF = m∠GIH
The figure is shown below.
The correct answer is m∠EIF = m∠GIH
Here lines FH and GE intersect each other at the point I.
we have to prove the angle
m∠EIF = m∠GIH
so,
m∠EIF+m∠FIG = 180° as angels ∠EIF and ∠FIG forming a linear pair summing up to 180°. angels ∠EIF and ∠FIG form straight angels on a line EG.
m∠FIG+m∠GIH= 180° as angels ∠FIG and ∠GIH forming a linear pair summing up to 180°. angels ∠FIG and ∠GIH form straight angels on a line FH.
m∠EIF+m∠FIG= m∠FIG+m∠GIH because of the substitution property of equality. we replace 180° by m∠FIG+m∠GIH.
m∠EIF = m∠GIH because of the subtraction property of equality. We can subtract the same elements from both sides by the subtraction property of equality.
Therefore m∠EIF = m∠GIH.
