What is the y-intercept for the quadratic
Y=4x^2 + 5x - 7?
Answer: (0,-7)
HOPE I HELPED
Step-by-step explanation:
Answer:
-7
Step-by-step explanation:
Since you are trying to solve for y, you set all the x values to 0.
(Y intercept occurs when x = 0, thats why you sub 0 for all x)
y= -4(0)^2[tex]y=-4(0)^{2} +5(0) -7[/tex]
this simplifies to
y=-7

1/3y y = 15
please help
Answer:
Step-by-step explanation:
y in (-oo:+oo)
(1/3)*y = 15 // - 15
(1/3)*y-15 = 0
1/3*y-15 = 0 // + 15
1/3*y = 15 // : 1/3
y = 15/1/3
y = 45
y = 45
Answer: The answer is five
Step-by-step explanation: This is because if the equasion is 1/3 x y and y=15 than the equasion is 1/3 x 15 or 1/3 x 15/1 which is 5

What two numbers multiply to -24 and add to -5?
The two numbers that multiply to -24 and add to -5 are 3 and -8
How to determine the numbersFrom the question, we have the following parameters that can be used in our computation:
Product = -24
Sum = -5
Let the numbers be x and y
So, we have
xy = -24
x + y = -5
Let x be 3 and y be -8
So, we have
3 * -8 = -24
3 - 8 = 5
The above equations are true
Hence, the numbers are 3 and -8

You decide to buy a custom frame for a painting which measures 4 by 6 inches. If the framing material costs $2 per inch, what is the total cost of framing material?
Answer:
6 x 4 = 24 x $2 = $48
Step-by-step explanation:
The total cost of the rectangular frame is C = $240.
What is rectangle?A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,
We need to find the total cost of framing material
The perimeter is given by:
P = 2x(L + W)
In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:
P = 2x(6in + 14in)
P = 2x20in = 40in
Since, the framing material costs $6 per inch, then the total cost of the frame will be:
cost = 40x$6 = $240

formulas A=bh/2 A=bh and I have 6in 4in 6in 10in and I have to find the area
Answer:
Lots of "ifs" here.
A=bh/2 is the formula for the area of a triangle.
A=bh is the formula for the area of a rectangle or a parallelogram.
If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2
If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2

Nancy started the year with $425 in the bank and is saving $25 each week. Sam started the year with $705 but is spending S15 a week. Write a system of equations that model the following situation.
Define cach variables with a "Let" statement, write two equations, and solve completely.
Answer:
Step-by-step explanation:
Let x equal number of weeks and y equal money in the bank.
Nancy, y=425+25x
Sam, y=705-15x
The system of equations:
Nancy: [tex]y=\$425+\$25x[/tex]
Sam : [tex]y=\$705-\$15x[/tex]
Given:
Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
To find:
The system of equations describing the given models.
Solution
1) Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Let the number of weeks Nancy saving her money be 'x'.
Let the total amount of money in Nancy's bank after x weeks be 'y'.
[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]
The equation for Nancy:
[tex]y=\$425+\$25x[/tex]
2)
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
Let the number of weeks Sam spending his money be 'x'
Let the total amount of money left in Sam's bank after x weeks ='y'
[tex]y=\$705-\$15\times x\\y=\$705-\$15x[/tex]
The equation for Sam:
[tex]y=\$705-\$15x[/tex]

What is the domain of y = tan x? A. (–∞, ∞) B. C. all D. all
Given:
The function is
[tex]y=\tan x[/tex]
To find:
The domain of the given function.
Solution:
We know that, domain is the set of x-values or input values.
We have,
[tex]y=\tan x[/tex]
[tex]y=\dfrac{\sin x}{\cos x}[/tex]
The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.
So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].
Note: All options are incorrect.
Answer:
C
Step-by-step explanation:
all x≠pi/2+pi n

Principal = $2,400
Rate = 4%
Time = 30 months
Answer:
$240
Step-by-step explanation:
I = prt
I = (2,400) (0.04) (2.5)
note: I changed 4% to a decimal and 30 months to 2.5 years
I = 96 (2.5)
I = 240 <-- The interest
------------------------------------------------------------------------------------------------------------
The simple interest accumulated on a principal of $ 2,400.00 at a rate of 4% per year for 2.5 years (30 months) is $240.00.

What is the sign of f on the interval?
The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.

What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:
Step 1: You must divide the numerator of the fraction by the denominator of the fraction.
Step 2: Now you must add the quotient obtained to the Whole number part.
So, you get:
3 + 1/4
=3 + 0.25
= 3.25
Then, the scale image that maps "Figure a" onto "Figure b" is:
1: 3.25
Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .
Therefore, you get that the result is:
x = 3 * 3.25
or, x = 9.75
Hence, The solution is : the value of x is x = 9.75.
