1) Write a system of equations to describe the situation below, solve using any method, and

1 answer:

7 0

This situation can be represented by

y = 33x + 223

y = 32x + 239

I still like substitution, so let’s plug in 33x + 223 into the second equation

33x + 223 = 32x + 239

Move the terms into appropriate sides

33x - 32x = 239 - 223

Combine like terms

x = 16

Then plug in x for any equation

y = 32(16) + 239

y = 751

The Canadian labor force as of 2019 was 32.7 million. There were 30.9 million employed What the unemployment rate would be?

Afina-wow [57]

Answer:

The unemployment rate would be 5.5%.

Step-by-step explanation:

It is given that,

The Canadian labor force as of 2019 was 32.7 million.

There were 30.9 million employed

We need to find the unemployment rate.

Unemployed = labor force - employed

= 32.7 - 30.9

= 1.8 million

$\text{unemployment rate}=\dfrac{\text{unemployed}}{\text{labor force}}\times 100\\\\=\dfrac{1.8}{32.7}\times 100\\\\=5.5\%$

So, the unemployment rate would be 5.5%.

2x - 4 - 6(x + 1) = 5x + 6 a) 8 b) -8/9 c) 4 d) -16/9

andriy [413]

Step-by-step explanation:

2x - 4 - 6(x + 1) = 5x + 6

2x - 4 - 6x - 6 = 5x + 6

2x - 6x - 5x = 4 + 6 + 6

-9x =16

x= -16/9

Hope this helps.. Good luck!

A system of equations has 1 solution. If 4x - y = 5 is one of the equations, which could be the other equation?

Nuetrik [128]

answer :

A. y = – 4x + 5

Step-by-step explanation:

make y = 4x-5 equal to each of the answer choices and see if you get an answer

STEPS:

make 4x - y = 5 into a y= equation

4x - y = 5 is y = 4x-5

then make y = 4x-5 equal to each of the answer choices and see if you get an answer

4x-5 = -4x+5

8x = 10

x = 10/8 = 5/4

yes, it has one solution

its also an intersecting line because

one line has 4x and the other has -4x

4x and -4x are slopes and opposite signs so

the lines are intersecting

4x-5 = 4x-5

since they are the same on both sides of the equal sign they have

infinite solutions

they are also both the same line

2y=8x-10 when simplified is y=4x-5

so its just like choice B

they are also both the same line

4x-5 = 4x-5 which is

0 = 0

since they are the same on both sides of the equal sign

infinite solutions

they are also both the same line

-2y=-8x-10 when simplified is y=4x+5

4x-5 = 4x+5 when you work it out you get the answer

0 = 5

since when you solve the equation and get 0 = 5

that means its there is no solution

its also parallel line because both lines have 4x as a slope

A wooden flagpole is 25 foot tall. In a storm, the flagpole is broken and its top touches the ground 5 foot from the base. Find

Mumz [18]

Answer: x = 12 ft

Step-by-step explanation:

let the erect part of the pole be x

the slanted part of the pole will be 25-x

the ground distance = 5

they form a right triangle

apply Pythagoras theorem

5^2+x^2=(25-x)^2

25+x^2=x^2 - 50x + 625

50x=625-25

50x=600

x=600/50

x=12 feet
