Answer:
[tex]m<49/12[/tex]
Step-by-step explanation:
we are given
[tex]y = 3x^2+7x+m[/tex]
To find x-intercept means we have to find zeros
and for finding zeros , we will use quadratic formula
and we have it has two x-intercepts
so, it's discriminant must be greater than 0
so, we will find discriminant
[tex]D = \sqrt{b^2-4ac}[/tex]
now, we can compare with
[tex]y=ax^2+bx+c\\y=3x^2+7x+m[/tex]
and then we can find a , b and c
a = 3, b = 7, c = m
now, we can find D
[tex]D = \sqrt{7^2-4*3*m} \\D=\sqrt{49-12m}[/tex]
It has two x-intercepts
so,
[tex]D = \sqrt{49-12m}>0[/tex]
now, we can solve for m
[tex]49-12m>0\\12m<49\\m<49/12[/tex]

Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)
Answer: y = -3.5x - 4.5
suppose: the equation of the line is y = ax + b ( a ≠ 0 )
because the line passes through (-2;2.5) => 2.5 = -2a + b
the line passes though (0;-4.5) => -4.5 = b
=> b = -4.5
2.5 = -2a + b
=> a = -3.5
b = -4.5
=> the equation of the line is y = -3.5x - 4.5

A right triangle has leg lengths of 3.4 cm and 6.7 cm. Which answer below shows the length of the triangle’s hypotenuse rounded to the nearest tenth?
A. 8.5 cm
B. 7.5 cm
C. 5.5 cm
D. none of the above
Answer:
D
Step-by-step explanation:
The hypotenuse squared is equal to the sum of the legs squared in a right triangle.
∴ c² = a² + b² (Pythagorean’s Theorem)
c² = 3.4² + 6.7² (substitute the given values for a & b)
c² = 11.56 + 44.89 (square both right hand terms)
c² = 56.45 (add the right hand side values)
c = √56.45 (square root of both sides)
c ≈ 7.5 to the nearest tenth QED

what do racecar drivers like to do
They like to flip over and set their car on fire
In general, racecar drivers like to engage in activities related to speed, adrenaline, and competition both on and off the race track.
Racecar drivers have a passion for speed and competition, which extends beyond their time on the track. When not racing, many of them enjoy activities that provide an adrenaline rush, such as go-karting, motocross, or other extreme sports. Staying physically fit is crucial for their performance, so they often participate in rigorous training, including cardio workouts, strength training, and reflex drills.
Additionally, they may spend time honing their racing skills through simulators or practice sessions on race circuits. Away from the track, some drivers may have interests in classic cars, car collecting, or automobile engineering. Their lifestyle revolves around the excitement of racing and everything associated with it, both professionally and recreationally.

How do I solve for c
Answer:
Uhhh add the top then divide by bottom
Step-by-step explanation:
Bc yes
Answer:
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]
Step-by-step explanation:
[tex] \dfrac{2bc + 5D}{3} = e + d [/tex]
Multiply both sides by 3.
[tex] 2bc + 5D = 3(e + d) [/tex]
[tex] 2bc + 5D = 3e + 3d [/tex]
Subtract 5D from both sides.
[tex] 2bc = 3e + 3d - 5D [/tex]
Divide both sides by 2b.
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]

Answer:
B (0, 1)
Step-by-step explanation:
(I’m not 100% sure about this)
Answer:
B. (0,1)Step-by-step explanation:
Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept.
y = m x + b
Find the values of m and b using the form y = m x + b .
m = 1
b = 1
The slope of the line is the value of m , and the y-intercept is the value of b .
Slope: 1
y-intercept: 1
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Choose 0 to substitute in for x to find the ordered pair.
Replace the variable x with 0 in the expression.
f ( 0 ) = ( 0 ) + 1
Simplify the result.
Add 0 and 1 .
f ( 0 ) = 1 The final answer is 1 . 1
The y value at x = 0 is 1 .
y = 1
Choose 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f ( 1 ) = ( 1 ) + 1
Simplify the result.
Add 1 and 1 .
f ( 1 ) = 2
The final answer is 2 . 2
The y value at x = 1 is 2 .
y = 2
Create a table of the x and y values.
x : 0,1
y: 1 ,2
Graph the line using the slope and the y-intercept, or the points.
Slope: 1
y-intercept: 1
x : 0,1
y : 1 ,2

2 + 3( 4x + 5) = -53
Answer:
x=-35/6
Step-by-step explanation:
2 + 3( 4x + 5) = -53
subtract 2 from both sides= 3(4x+5)=-55
divide both sides by 3 = 4x+5=-55/3
subtract both sides by 5 = 4x=-70/3
divide both sides by 4 = x=-35/6
x=-35/6 is your final answer
Answer:
Hope this helps :)
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
