Answer 1
Here we must see which information about the graph of a linear relationship is given. The information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.
Linear relationships:
So we define a general linear relationship as:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this problem we know that:
Originally, the sheet of ice is 2 meters thick.The thickness decays at a constant rateAfter 3 weeks, the thickness is 1.25 meters.
The first point gives us the y-intercept (the thickness at week 0), the second one gives us the fact that the relationship is linear, and the third one is just a point on the line (that can be used to get the slope.)
So the information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

The community garden has 35 equal-sized plots of land for rent. The cost to rent a plot in the garden for a year is $0.06 per square foot. What does it cost to rent one plot of land in the community garden for 1 year?
Answers
Answer:
$130.68
Step-by-step explanation:
1 acre = 43,560 square feet
3/4 of 43560 = 32,670 (So that would be 76,230 sq ft in 1.75 acres because 43560 + 32670 = 76230)
We need to divide the total by 35 plots.
76230 / 35 = 2178, using long division.
2,178 square feet is just one plot of 35. We need to multiply 2178 by 0.06.

If the value of the variable x is negative 3 then the value of the even function is 3. Then the correct option is C.
What is an even function?
Even Function - A true function f(x) is said to be an even function if the output value of f(-x) is the same as the f(x) for all values of x in the domain of f.
The equation should be stored in an even function:
f(-x) = f(x)
The function is given below.
f(x) = f(3) = 3
Let the function f(x) be an even function. Then we have
f(-3) = f(3) = 3

If f(x) = x4 âÂ’ x3 x2 and g(x) = âÂ’x2, where x ≠0, what is (f â„g)(x)?.
Answers
The composite function is [tex]f\circ g(x) = x^8+x^6+x^4[/tex]
Given that [tex]f(x)=x^4+x^3+x^2[/tex] and [tex]g(x)=x^2[/tex].
We need to calculate [tex]f\circ g(x)[/tex] which is a composite function.
If two functions are given and we create another function by using the given functions, then the new function is called composite function.
So to calculate the composite function, put the value of [tex]g(x) = x^2[/tex] in the function [tex]f(x)[/tex].
[tex]f\circ g(x) = (x^2)^4+(x^2)^3+(x^2)^2[/tex]
[tex]f\circ g(x) = x^8+x^6+x^4[/tex]
Hence the composite function is [tex]f\circ g(x) = x^8+x^6+x^4[/tex].

question: if Cory walks 3 units south and 4 units east, what would his new coordinate be?
Answers
Answer:
(5,-2).
_______________________
South is Negative Y axis.
East is Positive X axis.
(look at the compass in the top right corner)
Cory's current coordinates are (1,1).
When Cory walks 3 units south, he moves 3 steps downwards in the Y axis, which means if his current Y position is 1, we subtract 3, ( 1 - 3 = -2).
And when Cory moves 4 units east, Add 4 as he is walking in the positive X axis. (4 + 1 = 5).

Answer:
y = −3x+7
Step-by-step explanation:
m = slope
slope = change in y / change in x
slope = ▲y/▲x
slope = -3 / 1
slope = -3
y-intersect = (0,7)
The slope-intercept form of linear equation:-
y = mx + b
where:
m = the slope
b = y-intersect
*we plot the information we have get in the formula
y = mx + b
y = -3x + 7

Look at the number behind 7, it’s 5 if the number is equal to 5 or is more than 5 u add 1 more number so 7 is more than 5 so you add 1 more number its 3.98
Kensington City Cafe recently introduced a new flavor of coffee. They served 28 grande cups
and 33 jumbo cups of the new coffee today, which equaled a total of 1,207 ounces. The day,
before, 28 grande cups and 53 jumbo cups were served, which used a total of 1,667 ounces.
How much coffee is required to make each size
Answers
Answer:
jumbo 23 oz, grande 16 oz
Step-by-step explanation:
Use g for grande and j for jumbo
The first equation: 28g + 33j = 1207
The second equation: 28g + 53j = 1667
Subtract the first from the second
28g + 53j = 1667
- 28g + 33j = 1207
Equal 20j = 460
j = 23
Put 23 in for j in either equation and solve for g:
28g + 33(23) = 1207
28g + 759 = 1207
28g = 448
g = 16

4x=1/3(6x-30)-2
Answers
Answer:
x = -6
Step-by-step explanation:
Solve:
4x = 1/3(6x - 30) - 2
4x = 2x - 10 - 2
2x = -10 - 2
2x = -12
x = -6
Check:
4(-6) = 1/3(6(-6) - 30) - 2
-24 = 1/3(-36 - 30) - 2
-24 = 1/3(-66) - 2
-24 = -22 - 2
-24 = -24
