The table gives a few x,y pairs of a line, what is x intercept
Answer:
Intersections of Linear Equations. The intersection of a line are the points where the line intersects, or crosses, the horizontal and vertical axes. The line shown on the graph intersects the two coordinate axes. The point where the line crosses the x-axis is called [x-intercept].

Alyssa missed 64 questions on her multiple choice science final and earned a grade of 68%. How many total questions were on the final exam?
Answer: 94 questions
Step-by-step explanation:
is %
----- = -----
of 100
64 68 68 is the percent Alyssa got correct on the exam.
----- = ----- 64 is the questions she got wrong of an unknown total.
x 100 x is the unknown variable. (the total questions on the test)
Cross multiply to get this: 64*100 = 68x
6400 = 68x (Divide by 68 on both sides)
You should get about 94.11 after dividing. You have to round as there cannot be have a question. It should be rounded to 94 questions. There are 94 questions and 64 were missed. To check your work, do 64/94. This should give you about 68% after rounding.

Let U = {a, b, c, d, e, f, g}. Find the complement of the set A below.
A = {a, c, e, g}
Answer:
[tex]A' = \{b,d,f\}[/tex]
Step-by-step explanation:
Given
[tex]U = \{a, b, c, d, e, f, g\}[/tex]
[tex]A = \{a, c, e, g\}[/tex]
Required
Find the complement of A
The complement of A are elements in the universal set (U) but not in A.
In other words,
if [tex]A = \{a, c, e, g\}[/tex]
then A' are the elements other than a, c, e and g that are in the universal set
So
[tex]A' = \{b,d,f\}[/tex]
Where A' represents the complement
What is the y-intercept of the function f(x)=4 - 5x?
-5
-4
4
5
Answer:
4
Step-by-step explanation: Its 4 becuase you plug in the zero like this'
f(x)=4-5(0)
f(0)=4-0
f(0)=4
So it will (0,4)

Answer:
discrete
Step-by-step explanation:
This graph is discrete. A discrete graph has separate values, which are represented by multiple unconnected points. In continuous graphs, the values are all connected to each other. If this graph was continuous, then we would see a line rather than separate dots. The graph can also not be neither continuous nor discreet because it passes the vertical line test, meaning that it is a function.

A store is hoping an advertising campaign will increase their number of customers by 30%. They currently have about 80 customers a day.
Answer:
There will be 104 customers a day, after advertising campaign
Step-by-step explanation:
Current number of customers in a day in shop = 80
After advertising campaign, the customers will increase = 30%
So, new customers will be:
We can find new customers by adding new 30% customers to the current 80 customers.
First find 30% of 80
[tex]30\% \ of \ 30\\=\frac{30}{100}*80\\=24[/tex]
Now, add 24 to current 80 customers.
Number of customers = 80+24 = 104
So, there will be 104 customers a day, after advertising campaign

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. The angle of elevation of the tree from one position on a flat path from the tree is H=60°, and from a second position L=20 feet farther along this path it is B=50° What is the height of the tree?
Answer: 44.11 feets
Step-by-step explanation:
Using Pythagoras :
tan θ = opposite / Adjacent
Tan 60° = h / x
h = x tan 60 - - - (1)
tan 50° = h / (x + 20)
h = (x + 20) tan 50 - - - (2)
Equate (1) and (2)
x tan60 = (x + 20) tan 50
1.73205x = (x + 20) 1.19175
1.73205x = 1.19175x + 23.835
1.73205x - 1.19175x = 23.835
0.5403x = 23.835
x = 23.835 / 0.5403
x = 44.114380
Hence, height = 44.11 feets

1. Which of the following is the standard form of y = (x – 3)(x – 7)?
a. y = (x + 5)2 – 21
b. y = (x - 5)² - 4
c. y = (x + 5)2 - 4
d. y = (x – 5)2 + 28
A
B
9514 1404 393
Answer:
b. y = (x - 5)² - 4
Step-by-step explanation:
Here, we take "standard form" to mean "vertex form."
In the US, "standard form" would be ...
y = x² -10x +21
Vertex form is ...
y = (x -5)² -4 . . . . matches B

On the last day of vacation, the Ramirez family drove 252 miles from a state park to its home. The drive covered 35% of the total distance the family traveled during its vacation. What is the total distance the Ramirez family traveled during its vacation?
Answer:
Step-by-step explanation:
35 percent of total miles traveled (say T)is 252 miles.
(35/100) * T=252
T=(252*100)/35 => T=720 miles
So total distance the Ramirez family traveled during its vacation is 720 miles
Answer:
720 miles

If x + y = 13 and y = 2, then which of the following is true according to the
substitution property?
A) 2 + y = 13
B) x = 13 - y
NICy = 13 - x
OD) x + 2 = 13
Answer:
OD) x+2=13
Step-by-step explanation:
you would plug in the y substitute which would be 2, making the equation x+2=13
:) hope this helps lol
Answer:
X+2=13
Step-by-step explanation:
We know that x+y=13 when added. We also know that y=2. To find X we can add X to 2 to get 13. X=11
