Answer:
No, the student is incorrect.
Step-by-step explanation:
First we need to find the x-intercept. You can do so by solving for the variable x, and letting y = 0.
[tex]x+2(0)=5[/tex][tex]x=5[/tex]The x-intercept of the graph of [tex]x+2y=5[/tex] is at [tex](5,\ 0)[/tex], because the formula for a point on a graph is [tex](x, \ y)[/tex], where the x-value comes first.
The x-value is 5, and the y-value is 0, because that is what we substituted into the equation.
In other words, when the graph touches the x-axis at 5 (5, 0), the y-value of this point of intersection will be 0.
This student is NOT correct because the point they give (0, 5) is flipped from the correct x-intercept.

A 816-mile, 7-hour plane trip was flown at two speeds. For the first part of the trip, average speed was 111 mph. For the remainder of the trip, the average speed was 124 mph. How long did the plane fly at each speed?
Answer:4 hours at 126 mi/hr
t = time flying at 111 mi/hr
837 = 111t + 126*(7-t)
837 = 111t + 882-126t
-45 = -15t
t = 3 hours at 111 mi/hr

which number is bigger? 419.10 or 419.099? please help me I do NOT want homework!
Answer:
419.10 is greater than 419.099
Step-by-step explanation:
Answer:
419.10 or 419.1
Step-by-step explanation:
419.1 is greater than 419.099, since there is a number on the tenths place of 419.1, whereas the latter does not.
Plus, when you round 419.099 UP to the nearest tenth, you get 419.1.

Answer:
m∠z= 58.7
Step-by-step explanation:
Remember, all triangles sum up to 180 degrees.
So, the equation would be: 31.3+90+m∠z= 180.
Step 1- Add to simplify.
(31.3+90)+m∠z= 180
121.3+m∠z= 180
Step 2- Subtract to both sides.
121.3+m∠z= 180
-121.3 -121.3
m∠z= 58.7

What is the value of a + bc when a = 7, b = 4, and c=1/2
Answer:
9
Step-by-step explanation:
How I got my answer:
a+ bc turns into 7 + 4 x 1/2
First, you do 4 x 1/2 which equals 2 ( 4/1 x 1/2 = 2)
Then, you add 7 and 2
=9
The value of the expression a +bc for the values a=7, b = 4, and c = 1/2 is 4.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is a + bc. The value of the expression will be calculated as,
E = a + bc
E = 7 + ( 4 x 1/2)
E = 7 + 2
E = 9

Her average expenses for each presentation, including renting the auditorium, are about $18,000. The cost of meals, motels, jet travel, and support
nersonnel total $75.000 ner week_How many weeks will Ms Powell need to travel if she wants to earn $553 000 per vear?
Answer:
7 weeks.
Step-by-step explanation:
1000 x 40 = 40000
40000 x 7 = 280000
18000 x 7 = 126000
126000 + 75000 = 201000
280000 - 201000 = 79000

Find the first term of the arithmetic sequence in which a61= 293 and the common difference is -3,5
Answer:
503
Step-by-step explanation:
503+(-3.5(60)) equals 293
The first term of the arithmetic sequence is 503.
What is arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression
A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
Given that the arithmetic sequence in which a61= 293 and the common difference is -3.5.
The first term will be calculated as,
a₆₁ = a₁ + d(n-1)
a₁ = a₆₁ + 3.5( 60 )
a₁ = 293 + 210
a₁ = 503
Hence, the first term will be a₁ = 503.

"State A and state B are among the states with the most remaining drive-in movie screens. State A has 5 more screens than state B, and there are 55 screens total in the two states. How many drive-in movie screens remain in each state?"
Answer:
30 and 25
Step-by-step explanation:
To solve this, let's create a mathematical equation from it.
Let A represent State A, and B represent State B.
If state A has 5 more screens than state B, we can express this mathematically as
A = 5 + B
Again, there are 55 screens in total between the two states, so we say
A + B = 55
Now, from the 2 equations we have created, we solve simultaneously.
Since A = 5 + B, we put this in the second equation
(5 + B) + B = 55
5 + 2B = 55
2B = 55 - 5
2B = 50
B = 50/2
B = 25
With B being 25, we can find A as
A = 25 + 5
A = 30
Therefore, state A has 30 screens, and state B has 25 screens

As a fraction, 6 does not go into 11 2times. Only once. 1 5/6
Answer:
6/7
Step-by-step explanation:
11/6 is equal to 1.83 (rounded off) which is more than 1.
4/5 is equal to 0.8 while 5/6 is equal to 0.83 (also rounded off)
4/7 is equal to 0.57 (rounded off once again) and is lesser than 5/6
As 6/7 is equal to 0.86 (rounded off), we can safely say that it is between 1 and 5/6 even if we didn't eliminate the other fractions.

Answer:
use the relations involving inscribed angles and external angles
Step-by-step explanation:
Call the measure of angle ABC by the name B. An inscribed angle (B) is half the measure of the arc it subtends. Then long arc AC is 2B, and short arc ABC is (360°-2B).
The external angle P, 36°, is half the difference of these values.
(2B -(360°-2B))/2 = 36°
2B - 180° = 36° . . . . . . . simplify
2B = 180° +36° = 216° . . . . add 180°
B = 108° . . . . . . . . . . . . . . . . . . divide by 2
m∠ABC = 108°
