Answer:

Step-by-step explanation:

Amari= Graph C and Solution is (-6,-2)

Bella= Graph A and Solution is (3,4)

Carl= Graph B and Solution is (0,-3)

0 solutions because the slopes are the same. The lines will never cross because they are at the exact same angle.

No, I do not agree with Joey because the lines have different slopes and will lead to the system cross which is the solution.

1st graph: y=2x-1 and y=7 solution #1= (4,7)

2nd graph: y=-2x-3 and y=1/2x solution #2= (-2,1)

3rd graph: y=x and y= -1/5+6 solution #3= (5,5)

I had this exact same assignment a few months ago, my teacher didn't use the 2nd slide but I had the 1st and 3rd slide so this should help!

X+6+5x=6(x+1) is it an infinite solution or a no solution problem

goblinko [34]

Answer:

infinite solution/all real numbers

Step-by-step explanation:

x+6+5x=6(x+1)

Step 1: Simplify both sides of the equation.

x+6+5x=6(x+1)

x+6+5x=(6)(x)+(6)(1)(Distribute)

x+6+5x=6x+6

(x+5x)+(6)=6x+6(Combine Like Terms)

6x+6=6x+6

Step 2: Subtract 6x from both sides.

6x+6−6x=6x+6−6x

6=6

Step 3: Subtract 6 from both sides.

6−6=6−6

0=0

so it is infinite solution/all real numbers

For travel purposes,a touring company places all 33 travelers into equal sized groups . how many groups are there and how many t

Katyanochek1 [597]

There are 3 groups of 11 travellers each or 11 groups of 3 travellers each.

Since we have 33 travellers and we need to divide them into equal sized groups, we need to find the factors of 33.

<h3 /><h3>Factors of 33</h3>

So, 33 = 1 × 33 = 3 × 11

So, the two factors of 33 we require are 3 and 11.

<h3 /><h3>The groups of travellers</h3>

Since 11 × 3 = 3 × 11,

So, 3 × 11 implies that we can have 3 groups of 11 travellers each and,

11 × 3 implies that we can have 11 groups of 3 travellers each.

So, there are 3 groups of 11 travellers each or 11 groups of 3 travellers each.

Round to the nearest tenth.

inessss [21]

Answer: Angle A = 53.9 degrees

Step-by-step explanation: We have a right angled triangle with two sides clearly given and one angle to be calculated. If the angle to be calculated is angle A, then having angle A as our reference angle, line AC (10 units) is the adjacent, line CB is the opposite while line AB (17 units) is the hypotenuse. Having been given the adjacent and the hypotenuse, we can now use the trigonometric ratio as follows;

CosA = adjacent/hypotenuse

CosA = 10/17

CosA = 0.5882

By use of the calculator or table of values,

A = 53.97

Approximately to the nearest tenth,

A = 53.9 degrees

Can anyone solve this?

UkoKoshka [18]

Answer:

D) 26.04 ft

Step-by-step explanation:

Let's set up a equation with two ratios:

$\frac{miniature\ house}{real\ house}=\frac{miniature\ house}{real \ house}$

Plug in the given lengths into the equation:

$\frac{1in}{1.55ft}=\frac{16.8in}{x}$

We can solve this using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second by the denominator of the first):

$1x=16.8*1.55\\1x=26.04$
