can u help me pls I need the answer now .​

Answer:

x = -0.22   or x = -2.28

Step-by-step explanation:

2x^2 + 5x + 1 = 0

You use the quadratic formula: -b ±√5² - 4 x 2 x 1 ÷ (2 x 2)

-5 +√17 ÷ 4 = -0.22

-5 - √17 ÷ 4 = -2.28

Answer: k=8

Step-by-step explanation:

k/2 = 4

k = 4 x 2

k = 8

Check: 8/2=4

Answer:

[tex]k=8[/tex]

Step-by-step explanation:

[tex]\frac{k}{2} = 4[/tex]

Multiply both sides by 2 to isolate k

[tex]\frac{k}{2}(2) = 4(2)\\k=8[/tex]

Answer: C. Bisect DE at G.

Step-by-step explanation:

So, for triangle DEF , if we draw the median DG to the opposite side EF.

Here EF is the opposite side to vertex D.

So, G must be the midpoint of line segment EF.

So , we need to first mark G on EF.

i.e. we need to bisect EF at G.

So first step would be : Bisect EF at G.

The radius would be 2.2281 or 7/π

Answer:

B. (8,4)

Step-by-step explanation:

To find the solution of the system, look at where the lines intersect. The intersecting point is (8,4). The solution to the system of equations is (8,4).

Answer:

B. (8,4)

Step-by-step explanation:

We want to find when these two equations are equal. The long way is to actually solve them using elimination or substitution of the equations. But, we can see an easier and clever way to solve them.

There is one specific time when equations are equal and that is when their lines intersect or cross, notice the graph and where they intersect. That specific coordinate where they intersect is your answer, (8, 4)!

Answer:

32.6 - y= 10.2

Step-by-step explanation:

The equation to solve this problem can be written as

32.6 - y= 10.2

Where y is the number that was substracted from 32.6.

If we make y subject of formula we have

y= (32.6-10.2)

y=22.4

Which means the number that was substracted from 32.6 is 22.4 and there difference is 10.2

Answer:

A. 32.6 - y= 10.2

Answer:

x = 8

Step-by-step explanation:

Two tangent segments to a circle from the same external point are congruent, thus

WP = WQ , that is

3x - 6 = x + 10 ( subtract x from both sides )

2x - 6 = 10 ( add 6 to both sides )

2x = 16 ( divide both sides by 2 )

x = 8

Answer:

29568

Step-by-step explanation:

Given that:

Length of road = 2 miles

Number of people who can fit in a area of 5 feet by 5 feet = 14

To find:

Number of people that can fit in the road of the given dimensions.

Solution:

Given that one side 2 miles wide and 5 feet deep.

First of all, we need to find number of 5 feet by 5 feet block that can be made in the given dimensions.

2 miles = 10560 feet

Number of blocks = [tex]\frac{10560}{5}[/tex] = 2112

Number of persons that can fit in one block = 14

Number of persons that can fit in 2112 blocks = 14 [tex]\times[/tex] 2112 = 29568

Therefore, the answer is: 29568

Answer:

2 terms

Step-by-step explanation:

Step one:

given data

we are told that your uncle gives you $10 and you save $2 a week

the expression for the situation is

let the total be y

[tex]y=10 + 2w[/tex]

From the expression, there are two terms

the first term is the constant term which is 10

while the second term is 2w, the coefficient is 2

Answer:

5 units

Step-by-step explanation:

Step one:

Given data

Le the first number be x

and the second number be y

So

x*y= 10-----------------1

and

x+y= 7-----------------2

from eqn 1

x= 10/y

put x= 10/y in eqn 2

[tex]10/y+y= 7\\\\10/y= 7-y[/tex]

cross multiply we have

[tex]10=y(7-y)\\\\10=7y-y^2[/tex]

rearrange

[tex]y^2-7y+10=0[/tex]

the factors of the quadratic expression are

-5 and -2

[tex]y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\[/tex]

Step-by-step explanation:

Step-by-step explanation:

p=2(l+w)

30cm=2(n+6+n)

30cm\2=2n+6

15cm-6=2n

9cm=2n

n=4.5cm or w=4.5cm

l=w+6

l=4.5cm+6

l=10.5cm

Call the four people [tex]abc[/tex] and [tex]d[/tex].

We know:

[tex]\frac{a+b+c}{3}[/tex][tex]=42[/tex]

and

[tex]\frac{a+b+c+d}{4}[/tex][tex]=40[/tex]

Thus:

[tex]a + b + c = 126[/tex]

[tex]\frac{126+4}{4} = 40[/tex]

[tex]126 + d =160[/tex]

[tex]d = 34[/tex]

Answer:

1. y = 4x - 4

2. y = x + 2

3. y = -2x - 4

4. y = -x + 2

Step-by-step explanation:

Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.

Answer:

$4.68

Answer:

$4.68

Step-by-step explanation:

12x0.39=$4.68

Answer:

A.

The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.

B. y = 50x + 300

Step-by-step explanation:

A.

The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.

For all the years after is when the line graph goes up which means they are adding to their total number.

B.   For the city of Revere, they started out with 300 and are adding 50 Chromebooks every year.

Y represents the total and x is each counting year.

So the equation of the line is represented by y = mx + b

b is any constant which in this case is any initial amount (300)

and m is the rate/change which is the number represented by the value that will go up ever year of x (50)

So plug it all in equals:

y = 50x + 300

Answer:

(168,12)

Step-by-step explanation:

Substitute x = 10y+48 in the first equation.

[tex]10y + 48 + y = 180 \\ 11y = 180 - 48 \\ 11y = 132 \\ y = \frac{132}{11} \\ y = 12[/tex]

We have got the y-value. Our next goal is to find the x-value by substituting y-value in any given equations.

For me, I will be substituting y = 12 in the first equation.

[tex]x + 12 = 180 \\ x = 180 - 12 \\ x = 168[/tex]

Answer Check

Substitute both x-value and y-value in both equations.

[tex]168 + 12 = 180 \\ 180 = 180[/tex]

Our first equation is true for both values.

[tex]168 = 10(12) + 48 \\ 168 = 120 + 48 \\ 168 = 168[/tex]

Our second equation is true for both values.

Thus, the answer is (168, 12)
