Answer:
x-intercept: -1/7
y-intercept: 1/4
Step-by-step explanation:
change equation into standard form: 7x - 4y = -1
set 'x' to zero and solve for y: 0 - 4y = -1
y = 1/4
set 'y' to zero and solve for x: 7x - 0 = -1
x = -1/7
Determine the sample space of all of the possible outcomes one of choosing a card numbered 1, 2, 3, or 4, and a blue, green, or a yellow marble. How many outcomes involve a blue marble
Answer:
[tex]Sample\ Space = \{1\ Blue, 1\ Green, 1\ Yellow, 2\ Blue, 2\ Green,[/tex] [tex]2\ Yellow, 3\ Blue, 3\ Green, 3\ Yellow, 4\ Blue, 4\ Green, 4\ Yellow\}[/tex]
The number of occurrence that involve blue is 4
Step-by-step explanation:
Given
[tex]Card\ Number = \{1,2,3,4\}[/tex]
[tex]Marble = \{Blue, Green, Yellow\}[/tex]
Required
Determine the sample space
To determine the sample space, we have to select a card number and write it alongside the marble colours.
i.e.
[tex]Sample\ Space = \{1\ Blue, 1\ Green, 1\ Yellow, 2\ Blue, 2\ Green,[/tex] [tex]2\ Yellow, 3\ Blue, 3\ Green, 3\ Yellow, 4\ Blue, 4\ Green, 4\ Yellow\}[/tex]
Solving (b): Outcomes that involves blue marble
First, we list them out
[tex]Blue = \{1\ Blue, 2\ Blue, 3\ Blue, 4\ Blue}[/tex]
Number of occurrence is 4
What is (64x^2y^3)-1/2 as radical expression?
Answer:
[tex] \frac{1}{8xy \sqrt{y} } [/tex]
Step-by-step explanation:
[tex](64 {x}^{2} {y}^{3} )^{ - \frac{ 1 }{2} } \\ \\ = \frac{1}{(64 {x}^{2} {y}^{3} )^{\frac{ 1 }{2} } } \\ \\ = \frac{1}{ \sqrt{64 {x}^{2} {y}^{3}} } \\ \\ = \frac{1}{ \sqrt{ {(8xy)}^{2} y} } \\ \\ = \frac{1}{8xy \sqrt{y} } [/tex]
Зу + 9x = 12
y=mx+b
Answer:
y = -3x + 4
Step-by-step explanation:
3y + 9x = 12
subtract 9x
3y = 12 - 9x
divide by 3 on both sides
y = 4 - 3x
or
y = -3x + 4
Answer:
y=-3x + 4
Step-by-step explanation:
Convert standard form equation into y-intercept form
3y +9x=12
3y= 12-9x
Divide both sides by 3 to isolate the y (you can flip the equation if it is easier)
y= -3x+4
hope this helps and have a great day :)

Which isa zero of the quadratic function f(x) = 4x + 24x + 11?
Ox=9.25
Ox=-5.5
Ox=0.5
Ox=3.25
Answer:
b
Step-by-step explanation:
just took the test edg 22
Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The given quadratic function is f(x) = 4x²+24x+11
We have to find the zero of the function.
Let us use the quadratic formula to find the zero.
a=4, b=24 and c=11
Let us plug in these values in quadratic formula
x=- 24±√24²-4(4)(11)/8
=-24±√576-176/8
=-24±√400/8
=-24±20/8
=4(-6±5)/8
=(-6+5)/2 or -6-5/2
=-1/2 or -11/2
=-0.5 or -5.5
Hence, Option B is correct, -5.5 is the zero of the quadratic function f(x) = 4x + 24x + 11

The sum of the prices for the items(That's 2large baskets and small gift baskets) for the first customer is $57. So assuming the price of a large basket is x and small basket is y, then an expression for the first sentence is;
2x + 5y= 57
The sum of the prices for the second customer is $6 less than the first customer ( that's 57-6 which is $51). Since he bought 1 large basket and 10 small baskets and the price of each large basket is the same and the price of each small basket is the same they assume the same variable of x and y. So the expression of the second sentence is;
x+10y=51.
So the expressions will be;
2x+5y=57
x+10y=51
That's Option C

A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).
A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).
Answer:
the required equation to represent the total cost with respect to every hour will be
=》y = 42x + 65
Step-by-step explanation:
total cost (y) = charge to make a house call + additional charge for every our
so, total additional charge for x hours
= 42 × x = 42x
hence y = 65 + 42x ( where 65 is charge to make a house call , y is total cost and 42x is additional charge for x hours )

7. A city lot is twice as long as it is wide, If its perimeter is 480 units, what are the dimensions of the lot?
Answer:
Step-by-step explanation:
P = 480
P = 2 length + 2 width
but we also know that
2width = length
so plug that into the length
P = 2(2width) + 2 width
480 = 4 width + 2 width
480 = 6 width
80 = width
160= length
