Answer:
$87.32Step-by-step explanation:
Step one:
given data
we are told that the initial bill is $74
thereafter they gave a tip worth 18% of the bill
let us compute what 18% of $74 will amount to
Step two:
=18/100*74
=0.18*74
=$13.32
The added expenses is $13.32
Hence the total cost is
the initial bill plus the tip
=74+13.32
=$87.32
(-12,14) and (6,-1) write the linear equation in slope-intercept form that passes through the given points. PLEASE HELP ASAP THANK YOU!!!
The equation of the line written in slope intercept form is 0.8333x + 24
From the question given :
x1 = - 12 ; y1 = 14 ; x2 = 6 ; y2 = - 1General form of a slope intercept equation :
y = bx + cb = slope = (y2 - y1) / (x2 - x1)
Slope = (-1 - 14) / (6 - (-12)) = - 15 / 18 = 0.8333
The intercept, c can be obtained thus :
14 = 0.8333(-12) + c
14 = - 10 + c
14 + 10 = c
c = 24
Therefore, the equation can expressed thus y = 0.8333x + 24

First, we need to find how much Beatrice earns each month, so you need to find the difference between the two- and four-month amount and divide by 2, which gives you 150. So, we know she gets 150 dollars each month. Multiply that by two to get 300, and subtract that from 850 to see how much she was awarded in the beginning, which was 550. So, the answer is G.

Please helpppp algebra
Answer: (-6,-9)
Step-by-step explanation: you probably don't wanna read this but in case someone asks you about it- first start by putting the first equation into graphing form, turning it into 2y=-3x+12.
then you can go ahead and multiply the second equation by two to get 2(y=1/2x-6), which is 2y=x-12.
next, just subtraction! 2y=-3x+12 minus 2y=x-12!
You get -4x=24, which leaves you to divide both sides by -4 to get x=-6!
now to put in x for the solution, you take a equation(either one) and put in x
[y=1/2(-6)-6]
[y=-3-6]
[y=-9]
so your points are (-6,-9)

Use any method to multiply (–14ab)(a + 3b – 4c).
Question 2 options:
A)
–14a2b – 42ab2 + 56c2
B)
14a2b + 42ab2 + 56abc
C)
–14a2b – 42ab2 + 56abc
D)
–14a2b – 42a2b2 + 56c
Answer:
-14 a^2 b - 42 a b^2 + 56 a b c C. is the answer
Step-by-step explanation:
Expand the following:
-14 a b (a + 3 b - 4 c)
Hint: | Distribute -14 a b over a + 3 b - 4 c.
-14 a b (a + 3 b - 4 c) = -14 a b a - 14 a b×3 b - 14 a b (-4 c):
-14 a b a - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b a = -14 a^2 b:
-14 a^2 b - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b×3 b = -14 a b^2×3:
-14 a^2 b + -14×3 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and 3 together.
-14×3 = -42:
-14 a^2 b + -42 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and -4 together.
-14 (-4) = 56:
Answer: -14 a^2 b - 42 a b^2 + 56 a b c
Ray and Claudia are writing in journals. Ray has written 16 pages and he now writes 2 pages every day. Claudia has written only 2 pages, but she now writes 4 pages every day. In how many days will they have written the same number of pages?
Answer:
6 days
Step-by-step explanation:
Step one:
Given data
For Ray
He has 16 pages already
Now he is writing 2 pages per day
let x be the number of days
and y be the total number of pages writen
the linear function for the situation is given as
y=2x+16-------------1
For Claudia
He has 2 pages already
Now he is writing 4 pages per day
let x be the number of days
and y be the total number of pages writen
the linear function for the situation is given as
y=4x+2-------------2
Step two:
let us equate equation 1 and 2 to find x
2x+16=4x+2
collect like terms
2x-4x=2-16
-2x=-12
divide both sides by -2
x=12/2
x=6
Therefore it will take 6 days for them to have the same number of pages

Solve for the unknown length.
Answer:
37.5 units
Step-by-step explanation:
I assume that there is condition: BC║DE . If so, then ΔABC ~ ΔADE ⇒ that corresponding sides are proportional.
[tex]\frac{BC}{DE}[/tex] = [tex]\frac{AC}{AE}[/tex]
AC = 30 + 20 = 50
[tex]\frac{x}{15}[/tex] = [tex]\frac{50}{20}[/tex] ⇒ x = [tex]\frac{15*50}{20}[/tex] = 37.5 units

f(x) = 2x, find the ordered pair when x = 1. O (1,2) 0 (4,1) (2,1) O (1,4)
Answer:
The ordered pair is (1, 2) ⇒ A
Step-by-step explanation:
In the function f(x) = y
x is the domain of the functiony is the range of the functionThe domain is all the x-coordinates of the points lie on the graph of the functionThe range is all the y-coordinates of the points lie on the graph of the functionThat means any ordered pair (x, y) satisfy the function f(x) = y, lies on the graph of the function
∵ f(x) = 2x
→ That means y = 2x
∵ x = 1
→ Substitute the value of x in the function above
∴ f(1) = 2(1)
∴ f(1) = 2
→ That means at x = 1, y = 2
∴ The ordered pair is (1, 2)
