Answer:
100 lima beans
Step-by-step explanation:
We can write an equation with s = string beans and l = lima beans:
s = 1.3l
We can now plug in 130 = s to get:
130 = 1.3l
We divide both sides by 1.3 and get:
100 = l
That means the lima bean plant produced 100 lima beans
Answer:
91
Step-by-step explanation:
130 * 30% =
130 * 0.3 =
39
130 - 39 = 91

What are the zeros of f(x)=(x+5)(x-9)?
Answer:
x= -5
x= 9
Step-by-step explanation:
Answer:
x = - 5, x = 9
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(x + 5)(x - 9) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 9 = 0 ⇒ x = 9

Explain in 1-2 sentences how you identify
proportional relationship
using a table or graph.
PLEASE helpppp
Answer:
You can tell because, as x increases/decreases, y increases/decreases at the same rate EACH TIME. This way, no matter how many times the proportions increase OR decrease, the ratio between x and y always stays the same.

Step-by-step explanation:
8x + 5x what is it simplify
Answer:
13x
Step-by-step explanation:
you would just add the 2 numbers together and then keep the variable. if you know the variable (if there’s a sheet to go off of) then multiply and add but otherwise it’s just 8 + 5 then add an x. 13x
=====================================================
Explanation:
x is a placeholder for a number. Think of it like a box holding a number. Conveniently, the letter 'x' is in the word 'box', so its naturally fitting to use x here.
Writing 8x could represent the idea of us having 8 boxes that are identical. Adding on 5x means we add on 5 more boxes. This leads to 8+5 = 13 boxes in total.
This is one way to see how 8x+5x = 13x
Another way is to write it like this: 8x+5x = (8+5)x = (13)x = 13x. I used the distributive property here.
Combining these terms is possible because 8x and 5x are like terms. They have the same variable and same exponent. We're adding two of the same type of object together.
determine an equation of a line in standard form that is perpendicular lo the line 2y = -x + 3 and passes through the point (4, 5).
1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2
Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.
Hence the price of a pencil is $3 and the price of a notebook is $4. (C)
answer is c) pencils: $3 notebook: $4 go to card 5
-6×-15=4×+35 i need help with this problem
Answer:
x = -5
Step-by-step explanation:
-6x - 15 = 4x + 35
+ 15 + 15
-6x = 4x + 50
-4x - 4x
-10x = 50
-10x/-10 = 50/-10
x = -5
Problem 2
A jewelry store purchased a pair of earrings for $54
before a markup was applied.
There was a 90% markup. After the markup, a 6.5%
sales tax is added.
What is the total after markup and tax?
Answer:
$109.27
Step-by-step explanation:
100 + 90 = 190
54/100 X 190 = 102.60
100 + 6.5 = 106.5
102.60/100 X 106.5 = 109.269
monetary unit round to 2dp
109.27

Determine which function has a greater change of rate.
Be sure to show work as well.
Answer:
A
Step-by-step explanation:
You need to find the slope in A. y = x + (4x - 1) = 5x -1. The slope is 5.
In B, as x increases 1 unit, y increases 1 unit. Therefore, the rate of change is 1/1 = 1
Conclusion: In A the rate of change is 5 and in B the rate of change is 1.
Therefore, A has a greater rate of change
Pls help me will mark brainliest................
Answer: A) 356.48m²
Step-by-step explanation:
divide up the shape:
square:
a=s*s
16*16=256m^2
Semicircle:
a = 0.5*πr²
(r would be half of a square side which is 8)
0.5*3.14*64=100.48
Add up the shapes:
100.48+256=356.48m²
