Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to
where
a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have
we have
The leading coefficient is negative, that means the parabola open downward
The zeros of the function are
Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore
The x-intercepts are (4,0) and (-1,0)

how can you divide integers
Answer:
When you divide integers with two positive signs, Positive ÷ Positive = Positive → 16 ÷ 8 = 2.
...
Division of Integers.
Types of Integers Result Example
Both Integers Positive Positive 16 ÷ 8 = 2
Both Integers Negative Positive –16 ÷ –8 = 2
1 Positive and 1 Negative Negative –16 ÷ 8 = –2

In a survey of 1,400 people who owned a certain type of car, 840 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
60%
Step-by-step explanation:
x/100 = 840/1400
cross multiply
100*840 = 1400*x
84,000 = 1400*60
84,000 = 84,000
x=60
Can someone explain how I solve both of these? I’m sort of lost
Answer:
#1) Well buying something 15 percent cheaper is like saying your buying something for 85% of its normal price.
Well a tax is adding onto somethign right? A percent means out of a hundred. A 5 percent tax is addding 5 percent to the hundred so really your paying 105 percent of the price. Convert into decimal you get 1.05
So assuming y is the original and the state Tax being 5% then
(y*0.85)1.05 (last option)
#2) Well we now x is adult tickets and y is child.
Adult tickets are $74
Youth is $35
Now we want to know c or total.
So 74x+35y=c (last option)

Linda is comparing the density of materials. The redwood is 2x10^ -2 pounds per cubic unit. The stainless steel is 3 x 10^ -3
Scientific to standard please
Answer:
I think this is right, if not let me know and i will try to find my mistake. The redwood would be 0.20 and the stainless steel would be 0.030.
Step-by-step explanation:
To change a number from scientific notation to standard form, move the decimal point to the left if the exponent is negative. However if the exponent were to be positive, you would move it to the right. You move to the left (in this case) by 2 for the redwood. For the stainless steel you would do the same thing but the exponent is -3, so you would move the decimal to the left by 3.

What is the constant of proportional for y=5x+3?
Answer:
The constant of proportionality on the equation is 5.
To obtain the constant of proportionality ;
We compare the general direct proportionality relation with the equation given.
The equation given : y = 5x
The direct relationship between y and x is :
y α x
y = kx - - - (1)
Where, y and x are variables and k is the constant of proportionality.
Comparing equation (1) with the equation given :
y = kx
y = 5x
We can observe that, k in the equation (1) equals to 5 in the given equation.
Hence, the constant of proportionality is 5

The massaging chair at the airport cost $5.25 for every 10 minutes. The chair was used for 1/2 and hour in the morning, 20 minutes in the afternoon and 3 hours and 40 minutes in the evening. How much money should have been deposited into the chair that day?
A. $23.63
B. $136.50
C. $141.75
D. $147.00
Answer:
C
You just count how many tens are for each one (30 min = 3 tens; 20 min = 2 tens; 3 hours = 18 tens; 40 min = 4 tens), which adds up to 27 tens. Since it costs $5.25 for every ten minutes, the total would be 27 x 5.25, or $141.75, which means the correct answer is C.
Calculations
3 + 2 + 18 + 4
27 x 5.25 =
3 2/5 x - 5 1/3 = -2 3/5 x +2/3
solve for x
