Consider the following pair of equations.
Y = x + 4
Y = -2x - 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write down the solution in (x, y) corn.

Answers

Answer:

(- 2, 2 )

Step-by-step explanation:

Given the 2 equations

y = x + 4 → (1)

y = - 2x - 2 → (2)

Substitute y = x + 4 into (2)

x + 4 = - 2x - 2 ( add 2x to both sides )

3x + 4 = - 2 ( subtract 4 from both sides )

3x = - 6 ( divide both sides by 3 )

x = - 2

Substitute x = - 2 into either of the 2 equations abd evaluate for y

Substituting into (1)

y = - 2 + 4 = 2

solution is (- 2, 2 )

Answers

Answer:

72.5°

Step-by-step explanation:

180° is a straight line. Subtract 35° from 180°, you get 145°, now divide 145° by 2, you will get 72.5°.

Hope this helped.

The sum of all angles is 360

we have one angle given which is 35 degrees the angle infront of it is also the same as opposite angles are always equal

so x= 35

for y as said earlier opposite angels are equal so the empty 2 angles are also y

so now we have

[tex]4y+35+35=360\\4y+70=360\\4y=290\\y= 72.5[/tex]

so y=72.5 degrees

Its going by 3, im pretty sure u cant get to 220.

Answer: No

Step-by-step explanation:

1. The pattern is +3 because

-4+3=-1

-1+3=2

2+3=5

5+3=8

2. To see if 220 is in the sequence and the starting point is -4 instead of 0, subtract 220-(-4)=224. Since 224/3 is 74.6666666667, which is not an integer, then 220 does not appear in the sequence.

What is 10z when z = 0.8

Plssss help mee

Answers

Answer:

Value of 10z = 8

Step-by-step explanation:

Given:

Equation of variable;

10z

and value of z = 0.8

Find:

Value of 10z

Computation:

We know that in given equation 10z

10 is constant(fixed value) and z is variable(changeable value)

where value of variable z is given 0.8

So,

By putting value of variable z in given equation

⇒ 10z

⇒ 10(0.8)

by multiplying variable and constant

Value of 10z = 8

Answer:

x = 660

Step-by-step explanation:

Solve

Write the proportion where x is the number of infected elk

6/50 = x/5,500

Cross multiply

5500 ÷ 50 = 1100 x 6

Answer:

45/7 rounds

6 3/7 rounds

Step-by-step explanation:

Here is the full question

Nicole is playing a video game where each round lasts 7/12 ​ fraction of an hour. She has scheduled 3 3/4 fraction hours to play the game. How many rounds can Nicole play? rounds

Number of rounds she can play = total time she has scheduled / length of each round

length of each round = 7/12

total time she has scheduled = 3 3/4

3 3/4  ÷ 7/12

3 3/4 x 12/7

convert to the total time scheduled to an improper fraction

to convert to improper fraction, take the following steps :

Multiply the whole number (3) by the denominator (4) = 3x 4 = 12 Add the numerator to the answer gotten in the previous step = 14 + 3 = 15 divide the number gotten in the previous step by the denominator = 15/4

PLZZZZZ HELPPPP!!!! i'm very confused on what to do !!!! what is the length of the apothem of a regular hexagon with 16cm side lengths round to the nearest tenth

Answers

Answer:

A = 4.6 cm

Step-by-step explanation:

Here, we want to find the length of the apothem, given the side lengths

Mathematically, we have this as;

A = s/2 tan (180/n)

where in this case;

s is the length of the sides which is 16 cm

n is the number of sides (since it is hexagon, we have this as 6)

Substituting these values;

A = 16/2 * tan (180/6)

A = 8 * tan 30

A = 4.62

To the nearest tenth, A is 4.6 cm
