Find a linear equation that is perpendicular to y= 2x + 4 and passes through (-5, -3)

Mathematics
1 answer:
Trava [24]3 years ago

Answer:

y=-1/2x+7/2

Step-by-step explanation:

two lines are perpendicular if the product of the slopes is equal to -1

the slope for y=2x+4 is 2

2*x=-1

x=-1/2

the formula for the slope is

(y2-y1)/(x2-x1)=m

we know y1 and x1

(y+5)/(x+3)=-1/2

y+5=x+3/2

2y+10=x+3

2y=x-7

y=-1/2x+7/2

natita [175]

Answer:

x = 1

Step-by-step explanation:

To solve an equation for a variable, we need to isolate (get the variable alone on one side)

(the order of the following was determined by PEMDAS)

5x + 5 = 5 (10 ÷ 5)   [simplify inside parentheses]

5x + 5 = 5 (2)

5x + 5 = 10

     - 5    -5             [subtract 5 from both sides to isolate x]

5x = 5

÷5    ÷5     [divide both sides to get x]

x = 1

hope this helps!!

The object below is made of solid plastic. It is a cylinder with an indentation at the top in the shape of a cone. What is the v
Anastasy [175]

Answer:

97.6 cm³

Step-by-step explanation:

Volume of plastic object :

Volume of cylinder - volume of cone

From. The diagram. :

Radius, r = diameter /2 = 4/2

Volume of cylinder = pi*r²h

V = 22/7 * 2² * 8 = 100.53096 cm³

Volume of cone = 1/3*pi*r²h

V = 1/3 * 22/7 * 2² * 8

V = 2.9321531 cm³

(100.53096 - 2.9321531) cm³

= 97.598 cm³

= 97.6 cm³

The owner of a local farm sells baskets of fresh tomatoes in the summer time. Each basket is priced according to its mass rounde
elixir [45]

Answer:

4 1/10 kg

Step-by-step explanation:

To find the total mass, we add the mass of the three baskets

1 1/10 + 1 3/10 + 1 7/10

Since they have the same denominator

 1   1/10

 1   3/10

 1   7/10

-------------

 3  11/10

Change the improper fraction to a mixed number

11/10 = 1 1/10

3 + 1 1/10

4  1/10
