Answer: m> 49/12
Step-by-step explanation:
The graph is a parabola . The Parabola with minimum point. So, Substitute the minimum value in the equation. Thus the graph of have two x-intercepts when.
The graph is a parabola with the minimum where x= -b/2a = -7/6.
To have 2 x intercepts, the value at the minimum point must be less than 0, i.e.
3(49/36) - 49/6 + m < 0
49/12 - 49/6 + m < 0
(49-98)/12 + m < 0
-49/12 + m < 0
m < 49/12
The values of m < 49/12 the equation of the function y = 3x² + 7x + m have two x-intercepts option (C) m < 49/12 is correct.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
It is given that:
The equation of the graph:
y = 3x² + 7x + m
If the above quadratic function has two x-intercepts that means:
D > 0
b² - 4ac > 0
On comparing:
a = 3
b = 7
c = m
7² - 4(3)(m) > 0
49 - 12m > 0
12m < 49
m < 49/12
Or
m ∈ (-∞, 49/12) for which graph of a function have two x-intercepts
Thus, the values of m < 49/12 the equation of the function y = 3x² + 7x + m have two x-intercepts option (C) m < 49/12 is correct.

My question is, on Sunday, 77,098 fans attended a New York Jets game. The same day, 3,397 more fans attended a New York Giants game than attended the Jets game. Altogether, how many fans attended the games? Round each number to the nearest thousand to find an estimate of how many fans attended the games.
Answer:
Total number of fan = 80,495
Step-by-step explanation:
Given:
Number of fans attended = 77,098
Additional number of fans attended = 3,397
Find:
Total number of fan
Computation:
Total number of fan = Number of fans attended + Additional number of fans attended
Total number of fan = 77,098 + 3,397
Total number of fan = 80,495
If $a$ is the $x$-intercept, $b$ is the $y$-intercept, and $m$ is the slope of the line with equation $\frac{x}4 + \frac{y}{12} = 1$, then what is the value of $a + b + m$?

GET ECKED
Answer:
13
Step-by-step explanation:
This is my first time posting, so sorry if this isn't that clear.
Anyways:
We want to find the x-intercept, and the y-intercept. The x-intercept will always have 0 as y, and the y-intercept will always have 0 as x.
We can find the x-intercept by plugging in 0 as y. So:
x/4+0/12=1
x/4=1
x=4
a=4 (since a is equal to the x-intercept.)
We can find the y intercept by plugging in x as 0:
0/4+y/12=1
y/12=1
y=12
b=12
We can find the slope by using the equation y2-y1/x2-x1, but theres an easier way. Simplifying the original equation x/4+y/12=1 into y=--3x+12 immediatly gets us the slope of -3.
So, 12+4-3=13.
(In case you didn't know how I got y=-3x+12. This is how:
x/4+y/12=1
12(x/4+y/12)=1(12)
3x+y=12
y=-3x+12 )

What does negative 3 over 5 > −2 indicate about the positions of negative 3 over 5 and −2 on the number line?
So,
Ignore the negatives and just make them positives.
For now.
Then, you look at 3/5 and say... it's 3 ticks towards the number five,
meaning it's between 4 and 5. After you do that whats happens is you place back the negatives and you have -3/5 and -2.
-2 < 5 and -2 < 4
Meaning it goes more to the left.

52-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is two inches more than seven times the length of the first piece. Find the lengths of the pieces. The lengths of the first, the second, and the third pieces are in, in, and in respectively.
Answer:
First piece = a = 5 inches
Second piece = b = 10 inches
Third piece = c = 37 inches
Step-by-step explanation:
Let us represent:
First piece = a
Second piece = b
Third piece = c
52-inch piece of steel is cut into three pieces.
a + b + c = 52 inches
The second piece is twice as long as the first piece
= b = 2a
The third piece is two inches more than seven times the length of the first piece.
= c = 2 + 7(a)
Find the lengths of the pieces. The lengths of the first, the second, and the third pieces are in, in, and in respectively.
a + b + c = 52 inches
Substitute 2a for b
2 + 7a for c
a + 2a + 2 + 7a = 52
Collect like terms
10a = 52 - 2
10a = 50
a = 50/10
a = 5 inches.
b = 2a
b = (2 × 5)
b = 10 inches
c = 2 + 7a
= 2 + 7(5)
= 2 + 35
= 37 inches

A math test had 26 questions. The questions were either true/false or multiple choice. The true/false questions were worth 2 points each and the multiple choice were worth 5 points each. If the test is worth 100 points, how many of each type of question are included on the test?
Answer:
True/ false type 10 questions
Multiple choice type 16 questions
Step-by-step explanation:
Using the given formation we can make equations to solve for the number of questions of either type is to be included
let the no of true/false be =x
let the number of multiple choice to be included be = y
x + y=26 .............(1)
now making the equation of points
2x + 5y = 100 .........(2)
substitute y = 26-x from first equation in the second equation
2x + 5(26 - x ) = 100
2x - 5x + 130 = 100
3x=30
x=10
y =26-10=16

Brian, Chris, and Damien took a math test that had 20 questions. The number of questions Brian got right is 14 more than the number of questions Chris got right. Damien correctly answered 2 less than the number of questions Chris answered correctly. If Brian and Damien have the same score, which statement is true?
Answer:
C. Brian and Damien both answered 2 more questions correctly than Chris did.
Step-by-step explanation:
A. Brian and Damien both answered 2 fewer questions correctly than Chris did.
B. Brian and Damien both answered 4 more questions correctly than Chris did.
C. Brian and Damien both answered 2 more questions correctly than Chris did.
D. Brian and Damien both answered 4 fewer questions correctly than Chris did.
Let
B = number of questions Brian got right
C = number of questions Chris got right
D = number of questions Damien got right
The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right.
B = 14 + (1/4) * C
Damien correctly answered 2 less than 5/4 the number of questions Chris answered correctly.
D = (5/4) C - 2
If Brian and Damien have the same score,
14 + (1/4) * C = (5/4) C - 2
14 + 1/4C = 5/4C - 2
14 + 2 = 5/4C - 1/4C
16 = 5C-C/4
16 = 4/4C
C = 16
B = 14 + (1/4) * C
= 14 + 1/4*16
= 14 + 4
= 18
D = (5/4) C - 2
= 5/4*16 - 2
= 5*4 - 2
= 20 - 2
= 18

Consider the equation −3+(−9.25)+m=0 .
Let's solve your equation step-by-step.
−3−9.25+m=0
Step 1: Simplify both sides of the equation.
−3−9.25+m=0
−3+−9.25+m=0
(m)+(−3+−9.25)=0(Combine Like Terms)
m+−12.25=0
m−12.25=0
Step 2: Add 12.25 to both sides.
m−12.25+12.25=0+12.25
m=12.25
Answer:
m=12.25
