Answer:
x = 7
Step-by-step explanation:
These angles are corresponding angles which mean that they're equal to each other:
7x - 4 = 5x + 10
7x - 5x = 10 + 4
2x = 14
x = 14/2
x = 7

Given the zeros of the function f (x) = x4 + 3x3 – 28x², identify whether the zero is a bounce or
cross.
Answers
f(x) = x^4 + 3x^3-28x^2
Factorising, we get
f(x) = x^2(x+7)(x-4)
Therefore, there is a double root at x = 0 and singular roots at x = -7 and 4
double roots tend to bounce, kind of like the standard quadratic y = x^2
singular roots tend to cross, kind of like a straight line on a graph, y = mx + b
Therefore, it bounces at x = 0, and crosses at x = -7 and 4
In general, a root raised to an even power bounces, and a root raised to an odd power crosses.

A plant measures 10 cm and increases in height by .02 percent each day, upon conclusion it measures 11.04 cm. What is a reasonable domain to plot the growth function?
Answers
Answer:
the correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.
Step-by-step explanation:
I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2

Answer:
50x+20=ur mom
Step-by-step explanation:
Answer:
t = 20 + .50m
m = number of miles travelled
t = total cost
Step-by-step explanation:
t represents the total cost and m represents the number of miles travelled. Since it costs .50 per mile, you would do .50m so that you could calculate the cost based on the number of miles and since the truck at first cost 20 dollars, you would add that to the equation to. This gives you t = 20 + .50m.

Explain how to compare decimals. Use the numbers 6.75 and 6.732 to
help you explain this process.
Answers
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732

Problema Solution
There were 155 people at the basketball game. Tickets for the game are $2.50 for students and $4 for adults. If the total money received for admission was $492.50, how many students and adults attended the game?
Answer provided by our tutors
let
s = the number of student tickets sold
a = the number of adult tickets sold
there were 155 people at the basketball game
s + a = 155
the total money received for admission was $492.50
2.50s + 4a = 492.50
by solving the system of equations
s + a = 155
2.50s + 4a = 492.50
we find
s = 85 students
a = 70 adults

Last week, Norma sold 80% of the peanut butter squares she baked. She sold 24 peanut
butter squares.
Answers
Answer:
since Norma sold 24 of the peanut butter squares that she baked and it is 80% of it. There is only 20% of the peanut butter squares she has baked. Leaving it to be only 6 peanut butter squares left.
This is because 24 is the 80% of 30. She had 30 in total and sold that 80% which is 24. So, therefore it leaves 6 peanut butter squares left. Making it 20% of what Norma baked.
