factorise 2x^2 + 7x + 3

Answer:

x (is greater than or equal to) -24

Step-by-step explanation:

x/-6 - 8 (is greater than or equal to) -12

add 8 to both sides

x/-6 (is greater than or equal to) 4

multiply both sides by -6

x (is greater than or equal to) -24

sorry I didnt know where to find the sign so I just wrote is greater than or equal to

Answer:

[tex]9\ m/s^2[/tex]

Step-by-step explanation:

For a moving object, the force acting on the object varies directly with the object's acceleration.

F ∝ a

or

[tex]\dfrac{F_1}{a_1}=\dfrac{F_1}{a_2}[/tex]

Put F₁ = 8 N, a₁ = 4 m/s², F₂ = 18 N and a₂ = ?

Put all the values,

[tex]\dfrac{8}{4}=\dfrac{18}{a_2}\\\\2=\dfrac{18}{a_2}\\\\a_2=9\ m/s^2[/tex]

So, the new acceleration is [tex]9\ m/s^2[/tex].

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 8 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, then

y = - 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = - 3x + 5 ← equation of line

Answer:

  $6.87

Step-by-step explanation:

The cost of 0.6 pounds of blueberries is ...

  (0.6 lb)($3.98/lb) = $2.39

The cost of 1.8 pounds of clementines is ...

  (1.8 lb)($2.49/lb) = $4.48

Then the total cost of the purchase is ...

  $2.39 +$4.48 = $6.87

The combined cost is $6.87.

Answer:

Step-by-step explanation:

X is less than 10 because you have the plus in the equation and so it as to be less than ten so that when you multiply it by 10 it equals less than 100. I don’t know if my explanation makes sense but I hope it helps.

[tex]\large\boxed{\tt x=2}[/tex]

Step-by-step explanation:

[tex]\textsf{We are asked to solve for the value of x.}[/tex]

[tex]\textsf{We are given an equation where x is on both sides of the equation.}[/tex]

[tex]\large\underline{\textsf{Solving;}}[/tex]

[tex]\textsf{Begin solving by adding x to both sides of the equation to cancel out -x on the right}[/tex]

[tex]\textsf{side of the equation. Afterwards, simplify the left side of the equation to evaluate}[/tex]

[tex]\textsf{x.}[/tex]

[tex]\large\underline{\textsf{Evaluating x;}}[/tex]

[tex]\tt -2 + x= -x + 2[/tex]

[tex]\textsf{Remove the -x on the right side by adding x to both sides of the equation.}[/tex]

[tex]\tt -2 + x +\boxed{\tt x} = -x + \boxed{\tt x}+ 2[/tex]

[tex]\tt -2 + 2x = 2[/tex]

[tex]\textsf{Now, we should simplify the left side of the equation as there's only a whole number}[/tex]

[tex]\textsf{on the right side of the equation.}[/tex]

[tex]\textsf{Remove the -2 on the left side of the equation by adding 2 to both sides of the equation.}[/tex]

[tex]\tt -2 + \boxed{\tt 2}+ 2x = 2 + \boxed{\tt 2}[/tex]

[tex]\tt 2x = 4[/tex]

[tex]\textsf{Lastly, divide both sides of the equation by 2 to find the value of x.}[/tex]

[tex]\tt \frac{2x}{2} = \frac{4}{2}[/tex]

[tex]\large\boxed{\tt x=2}[/tex]

Answer:

[tex] \sf \: x = 2[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -2 + x = -x + 2

Then the value of x will be,

→ -2 + x = -x + 2

→ x + x = 2 + 2

→ 2x = 4

→ x = 4 ÷ 2

→ [ x = 2 ]

Hence, the value of x is 2.

Answer:

4,9

Step-by-step explanation:

since y = x+5, substitute the second equation into the first

then the first equation becomes x+5=2x+1

solve and you get x=4

substitute x for 4 in the second equation and you get y = 9

Given:

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2).

To find:

The intersection point of medians DG and EH.

Solution:

We know that, intersection point of all the medians of a triangle is called centroid.

The formula of centroid is

[tex]Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)[/tex]

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2). So, the centroid of the triangle is

[tex]Centroid=\left(\dfrac{0+2+(-4)}{3},\dfrac{5+0+2}{3}\right)[/tex]

[tex]Centroid=\left(\dfrac{-2}{3},\dfrac{7}{3}\right)[/tex]

[tex]Centroid=\left(-0.666...,2.333\right)[/tex]

Round each coordinate to the nearest tenth.

[tex]Centroid=\left(-0.7,2.3\right)[/tex]

Therefore, the correct option is C.

Step-by-step explanation:

ok, so,

you know that

£3 is equal to 4 euros

this means that    0.75 pound is equal to 1 euro

       28.50/0.75=38

do 38 times 1, which means that it is 38 euros
