-3x^2-16x- 5

Answer:

read explanation

Step-by-step explanation:

rearrange equations to form y=mx+b

-2x+4=2y

-x+2=y

-y=-2x-5

y=2x+5

use these equations to find slope and y intercepts, and match those with the right graph

slope of first: -1

slope of second: 2

y-int of first: 2

y-int of second:5

Answer:

angle SRP AND ANGLE TUW

Answer: 40

Step-by-step explanation:

Find the reciprocal of the divisor

1/6: 6/1

Multiple it with the dividend

20/3 divided by 1/6= 20/3 x 6/1

20x6 = 120

3x1 = 3

Reduce the fraction: 40/1

Answer:

5484 gallons

Step-by-step explanation:

Given that:

Delivery in 1 day = 457 dozen gallons

g = number of gallons delivered on that day

Recall :

1 dozen = 12

Therefore, the number of gallons delivered in 1 day :

457 gallons * 12 = 5484 gallons

Answer:

30

Step-by-step explanation: First take the fastest speed of the squirrel, and then you multiply it by the percentage (250%). You can this by moving on decimal point to the left from the zero (250% = 2.50). Then multply the speed of the squirrel by said percentage of the girrafe,

12 x 2.5 = 30

Answer:

Answer:

3/10

Step-by-step explanation:

2/3 of 9= 6. So 2/3 of the 9/10=3/10

Answer: t= 11.5

Step-by-step explanation: 5 + (-11.5+3) = 3.5

Answer:

T = -3.7

Step-by-step explanation:

We begin with the given equation.

5(t+3)=-3.5

Distribute 5 throughout parentheses.

5t + 15 = -3.5

Move 15 to the other side and switch signs.

5t = -3.5 - 15

Combine like terms.

5t = -18.5

Divide by 5t.

t = -3.7

Answer: La durée de la vol entire est 560 millions de miles. La durée par hour est 2.19 millions de miles par hour.

Step-by-step explanation: Je ne sais pas sûr que Je comprends la question exactement. Si on doit trouver la durée par hour, il faut divider 560000000 par 255.

Answer:

The equation of perpendicular bisector of the line segment passing through  (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]

Step-by-step explanation:

Given points are:

(-5,3) and (3,7)

The perpendicular bisector of line segment formed by given points will pass through the mid-point of the line segment.

First of all we have to find the slope and mid-point of given line

Here

(x1,y1) = (-5,3)

(x2,y2) = (3,7)

The slope will be:

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{7-3}{3+5}\\m = \frac{4}{8}\\m = \frac{1}{2}[/tex]

The mid-point will be:

[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\ = (\frac{-5+3}{2},\frac{3+7}{2})\\= (\frac{-2}{2},\frac{10}{2})\\=(-1,5)[/tex]

Let m1 be the slope of the perpendicular bisector

Then using, "Product of slopes of perpendicular lines is -1"

[tex]m.m_1 = -1\\\frac{1}{2}.m_1 = -1\\m_1 = -1*2\\m_1 = -2[/tex]

We have to find the equation of a line with slope -2 and passing through (-1,5)

The slope-intercept form is given by:

[tex]y = mx+b\\y = -2x+b[/tex]

Putting the point (-1,5) in the equation

[tex]5 = -2(-1)+b\\5 = 2+b\\b = 5-2\\b = 3[/tex]

The final equation is:

[tex]y = -2x+3[/tex]

Hence,

The equation of perpendicular bisector of the line segment passing through  (-5,3) and (3,7) is: [tex]y = -2x+3[/tex]

Answer:

inequality is x < 6

Step-by-step explanation:

Answer:

x = -6

Step-by-step explanation:

undefined slope is always an x = line

so just do x = whatever x is

Step-by-step explanation:

For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.

=> (-z)² - 4(z - 5)(5) = 0

=> z² - 20(z - 5) = 0

=> z² - 20z + 100 = 0

=> (z - 10)² = 0

Therefore z = 10.
