Answer:
8(x + 14)
Step-by-step explanation:
The term product signifies multiplication in mathematics. However, in order to find a product, we must have two or more terms to multiply. Because we are finding the product of 8 and the sum of a number x and 14, we will place the sum in parentheses to show they are being added together.
Using this knowledge, we are left with the sum in parentheses (x + 14) and the number 8 to multiply it.
To simplify, this can be written as 8(x + 14).
Calculus is the relationship between change (in forms of rates, slopes, differentials) and content (measure by examples: volume, area, distance) It's a field that connects how big something is to how much it grows when small changes are made or, conversely, how knowing the rate that something is changing can tell you how much "stuff" you've accumulated.
a. True
b. False
Answer:
a. True
Step-by-step explanation:
Calculus is the mathematical study of continuous change. Calculus is usually developed by working with very small quantities. Calculus has two major branches, which are, differential calculus and integral calculus. Differential calculus involves instantaneous rates of change, and the slopes of curves, while integral calculus deals with the accumulation of quantities, and areas under or between curves.

Plz help I don’t understand
Answer: The answer is 700
Step-by-step explanation:
I hope is right?
Answer:
1. 20(-1) - (-4) (-5)= -40
2.[-12 + (-3 - 3)]= -18
Step-by-step explanation:
20(-1) - (-4) (-5)
=(20 * -1) - (-4 * -5)
(When 2 numbers are written next to each other in brackets without any sign in between them, it means multiplication)
=(-20) - (20)
= -20 -20
= -40
----------------------------------------------------------------------------------------------
[-12 + (-3 - 3)]
=[-12+(-6)]
=[-12-6]
= -18

Find the measure of AB if B is the midpoint of AC and AB = 2x - 4 and AC = 28
Answer:
AB=14
Step-by-step explanation:
First you write the equation 2(2x-4)=28 because if b is the midpoint then AB is half of the line so you multiply that half by two the make it equal to the whole line.
Then you distribute the two and get 4x-8=28.
Then you add 8 to 28 and get 36.
Then you divide 36 by 4 because the 4 and x are being multiplied together so you have to divide to get them apart.
So then you get x=9 and you aren't done yet because you have to plug x into 2x-4.
So it is 2(9)-4 which is 18-4 which equals 14.

There are 8 more boys than girls in the class. If there is a total of 32 students in the class, how many are boys
Answer:
There will be 24 boys, 32 -8 = 24
Step-by-step explanation:
In the class there is 20 boys.
What are monomials, binomials, polynomials ?All these are alzebraic expressions. A monomial consists of only one term, binomial contains two terms and a polynomial is when the number of terms is two or more than two.
In the given question
There are 8 more boys than girls in a class of total 32 students
let the number of girls be x according to the given data boys will be (x + 8)
∴ {x + (x+8)} = 32
2x + 8 = 32
2x = 24
x = 12
∴ the no. of girls = 12 and no. of boys = 12+8 = 20.

what is the standard form equation of the line shown below?
y + 1 = 1/2(x + 3)
y=1/2x+5/2
-x + 2y = 1
x-2y = -1
Answer:
- x + 2y = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (3, 2)
m = [tex]\frac{2-0}{3+1}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex], thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 2) , then
2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = 2 - [tex]\frac{3}{2}[/tex] = [tex]\frac{1}{2}[/tex]
y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{2}[/tex] ← in slope- intercept form
Multiply through by 2
2y = x + 1 ( subtract x from both sides )
- x + 2y = 1 ← in standard form

Answer:
D (4)
Step-by-step explanation:
So we have the function:
[tex]f(t)=3t^2+5t+6[/tex]
And we want to find f(-3).
To do so, substitute -3 for x. Thus:
[tex]f(-3)=3(-3)^2+5(-3)+6[/tex]
Square:
[tex]f(-3)=3(9)+5(-3)+6[/tex]
Multiply:
[tex]f(-3)=27-15+6[/tex]
Add:
[tex]f(-3)=18[/tex]
So, our answer is D (4)
9 more than 6 times a number is 3
Greetings from Brasil...
According to the statement of the question, we can assemble the following equation:
9 + 6X = 3
6X = - 6
X = - 1If the first term of AP is 4 and the sum of first five term is equal to one-fourth of the sum of the next five term, then find the 15th term?
Answer:
15th term = 116
Step-by-step explanation:
a= 4
Sum of an A.P = n/2 {2a + (n-1)d}
sum of first five term is equal to one-fourth of the sum of the next five term
5/2{ 2*4 + (5-1)d} = 1/4 × 10/2{2*4 + (10-1)d
5/2 {8 + 4d} = 1/4 × 5{ 8 + 9d}
40/2 + 20/2d = 1/4{ 40 + 45d)
20 + 10d= 40/4 + 45/4d
20 + 10d = 10 + 45/4d
20 - 10 = 45/4d - 10d
10 =45d - 40d /4
10 = 5/4d
Divide both sides by 5/4
10 ÷5/4 = d
10×4/5 = d
40/5 = d
8 = d
d= 8
Find the 15th term
15th term = a + (n-1)d
= 4 + (15-1)8
= 4 + (14)8
= 4 + 112
= 116
The 15th term is 116

AB = √(25 +144) = 13
All of the right triangles are similar, so ...
BC/BD = AB/AD
BC = BD(AB/AD) = 12(13/5)
BC = 31.2 . . . units

An airplane flew across the Pacific Ocean. The table shows the amount of time and the distance traveled when the airplane was traveling at a constant speed. What is the distance traveled for 2 hours? *
Answer:
Step-by-step explanation:
time(hours) | distance traveled(miles)
_____________|_______________________
2 | 1100
_____________|_______________________
3 | 1650
_____________|_______________________
6 | 3300
The distance covered by the airplane after 2 hours given a constant speed is 1100 miles
Since, the speed of the plane is said to be constant ;The speed of the plane can be calculated from the information in the table thus : Speed = distance ÷ time Distance traveled = 1650 miles ; time = 3 hours Speed = 1650 / 3 = 550 miles per hour Hence, the speed of the airplane = 550 miles per hour Distance covered in 2 hours will be : (Speed × time) Distance covered in 2 hours = (550 × 2) = 1100 milesThe distance covered by the plane in 2 hours is 1100 miles

Isabella is going to a carnival that has games and rides. Each game costs $2 and each ride costs $4. Isabella spent $40 altogether on 15 games and rides. Graphically solve a system of equations in order to determine the number of games Isabella played, x, and the number of rides Isabella went on, y.
Answer: (10,5)
Step-by-step explanation:
You have to graph it but the equations are
x+y=15 (total number of games and rides)
2x+4y+40 (total money spent)
first equation is also y= -x+15
second is 4y= -2x+40
y= -.5x+10
So graph y= -x+15 and y= -1/2x+10 and where the lines cross is your answer
also -x+15= -.5x+10
15=.5x+10
5=.5x
10=x
10+y=15
y=5

A. 12/5 B. 16/7 C. -16/7 D. -12/5 also side question, how do you find out if an equation has 1 solution or no solution or infinite solutions???
Answer:
A. ¹²/₅Step-by-step explanation:
There is no solution for system of equations: [tex]a_1x+b_1y=c_1\\a_2y+b_2y=c_2[/tex]
if: [tex]a_1=a_2\quad and\quad b_1=b_2\quad and\quad \bold{c_1\ne c_2}[/tex]
so first, we we need to transform the equations to the form where the coefficients at y will be the same:
[tex]kx-3y=4\\ 4x-5y=7\\\\ (kx-3y)\cdot5=4\cdot5\\ (4x-5y)\cdot3=7\cdot3\\\\ 5kx-15y=20\\ 12x-15y=21[/tex]
Now we have b₁=b₂ and c₁≠c₂ so the system has no solution if a₁=a₂

у/36 = 15/24 can someone walk me through this please?
Answer:
22¹/²
Step-by-step explanation:
y/36=15/24
cross multiply
y×24=36×15
24y=540
divide both sides by 24
y=540/24
y=22¹²/²⁴
break it down
y= 22¹/²
Answer:
22.5
Step-by-step explanation:
cross multiply
y/36 = 15/24
y×24 = 36×15
y×24 = 540
take 24 on the other side and divide it by 540
y = 540/24
y = 22.5
After three years, the value of a new car decreased from $25,000 to
$14,000. What was the percent decrease in the value of the car?
Answer:
56% decreaseStep-by-step explanation:
In this problem we are required to find the percentage decrease in the value of a car that originally cost $25,000
if the present value is now $14,000
we can solve for the percentage decrease by presentment the original cost of the car by the original cost and multiplying by 100
i.e = (14,000/25,000)*100
= (14/25)*100
= 0.56*100
= 56%
Hence the value of the car has decreased by 56%
