Answer 1

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]

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

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

Answers

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

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.

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.

Divide both sides by 2b.

Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)

Answers

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

Step-by-step explanation:

The equation Of the line is y =-3.5x-4.5
