The line which is having same y intercept as the line which passes through points (-4,0) and (0,3) is y=2x+3.
Given Points through which the line passes through are (-4,0) and (0,3)
We have to find the equation whose y intercept is equal to the y intercept of the line whose points given above.
First of all we have to find the y intercept of the line which passes through (-4,0) and (0,3). Equation of line is :
y-y1=(y2-y1)/(x2-x1)*(x-x1)
y-0=(3-0)/(0+4) *(x+4)
y=3/4(x+4)
y -intercept exists where x=0
put x=0
y=3
So the options are:
y=2x-4y=2x-3y=2x+3y=2x+4By putting the value of x in all options we will find
y=-4
y=-3
y=3
y=4
So the third option is correct.
Hence the line whose y-intercept matched with the given line is y=2x+3.

A factory stacks boxes according to their weights. To provide stability to the stacks of boxes, heavier boxes are placed at the bottom of the stack, and lighter boxes are placed at the top. However, because of the boxes’ material, a box can only be placed on top of another if its weight is exactly half the weight of the lower box. Also, due to the height of the warehouse ceiling, boxes can only be stacked 4 levels high. The factory director has asked for your help in answering some questions about these boxes.
a. Explain how you would find the weight of each stacked box if you knew the weight of the bottom box. Find the weight of each box in a stack of 4 boxes if the bottom box weighs 10 pounds.
b. Eventually, these stacks of boxes will go onto pallets for shipping. We need to know how much each stack weighs in order to know how many stacks we can put on each pallet, but the bottom boxes do not necessarily weigh 10 pounds.

What is the measure of arc ef
Answer: [tex]128^{\circ}[/tex]
Step-by-step explanation:
By the inscribed angle theorem, minor arc EG measures 92 degrees.
Since the circumference of a circle measures 360 degrees, arc EF measures [tex]360-140-92=128^{\circ}[/tex]
The measure of the arc EF = 128°.
What is an Arc?Arc is that part of the circumference of the circle which is formed by two points on the circle.
The angle subtended by an arc on the center of the circle is twice that it subtends on the circumference of the circle.
So,
The measure of arc EG = 2 * 46 = 92
The measure of arc GF = 140°
The complete circle has an angle of 360° at the center
The measure of the arc EF = 360 -mEG - mGF
The measure of the arc EF = 360 - 92 -140
The measure of the arc EF = 128°.
Therefore, The measure of the arc EF = 128°.

A spiral staircase turns $270^\circ$ as it rises 10 feet. The radius of the staircase is 3 feet. What is the number of feet in the length of the handrail
The number of feet in the length of the handrail is 17.3 ft.
The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle
The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft turned through 270°= (3/4) of a whole revolution
(3/4) (2pi) (3) = (9/2)pi ft = 4.5 pi ft
The side of the rectangle will be the rise of the staircase = 10ft
And the diagonal of the rectangle will be the length of the handrail
We can use the Pythagorean Theorem to solve this
Handrail length = √ [ (4.5 pi)^2 + 10^2 ] ≈ 17.3 ft

Answer:
(a) The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.
Step-by-step explanation:
The possible numbers of real zeros can be found using Descarte's Rule of Signs.
RuleWhen signs of coefficients of terms of the polynomial are listed in order of decreasing degree, the number of sign changes can be counted. That number is the number of possible positive real zeros of the polynomial.
When the signs of odd-degree terms are changed, the number of sign changes becomes the possible number of negative real zeros.
The actual number of real zeros may be less by a multiple of 2. (The zeros may be complex, and complex zeros come in pairs.)
ApplicationThe signs of the terms in the given polynomial are ...
+ - + + + . . . . . 2 sign changes: 2 or 0 positive real zeros
When the signs of odd-degree terms are changed, they become ...
+ + + - + . . . . . 2 sign changes: 2 or 0 negative real zeros
Descarte's rule of signs lets us conclude ...
The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.__

When we graph the function, we find there are no real zeros. All four of the zeros are complex.

If it is a valid criterion, explain why. If it is not valid, use GeoGebra to create a counterexample demonstrating that it doesn’t work and give an explanation.

How many acorns is Blue Jay going to store for the winter, and how many trees?
Answer:
4 trees and 76 acorns.
Step-by-step explanation:
Let the amount of trees be x.
[tex]18x+4=20x-4\\\\\implies2x=8\\\\\implies x=4[/tex]
There are 4 trees, and there are [tex]18x+4[/tex] acorns or 76 acorns.
Hope you have a nice day, and also you should mark brainliest :)
Answer:
76 acorns and 4 trees
Step-by-step explanation:
Let X be the number of acorns (a) Ms. Blue Jay plans to store.
We are told that she could hide 18 acorns (a) per tree (t) which we'll write as 18a/t. This would result in 4 leftover acorns.
We then learn that if she hides 20 acorns per tree, 20a/t, she will have space for an extra four acorns.
There are t trees in both cases. We can write these two scenarios as:
1) 18t + 4 = X [18 acorns are in each tree, t, plus there are 4 left over.]
2) 20t -4 = X [20 acorns per tree, t, with room to store 4 more]
These two are equal to each other:
18t + 4 = 20t - 4
2t = 8
t = 4
There are 4 trees.
Since 18t+4 = X, the total number of acorns is18*4+4 = 76 acorns and 4 trees.
Check to see if 76 acorns works for the second scenario:
Will hiding 20 acorns per tree leave room for 4 acorns if there are 76 acorns?
(4 trees)*(20 acorns/tree) = 80 acorns can be stored. If Ms. Jay only has 76 acorns, there will be room for 4 more acorns.
