this got me all confused ^^'
appreciate it if you help me....but if you cant thats ok! Have a great day either way^^​

Answer:

Cost of shrubs = 23

Cost of tree = 47

Step-by-step explanation:

Let

Cost of shrubs = x

Cost of tree = y

13x + 4y = 487 (1)

6x + 2y = 232 (2)

Multiply (2) by 2

12x + 4y = 464 (3)

13x + 4y = 487 (1)

Subtract (3) from (1)

13x - 12x = 487 - 464

x = 23

Substitute x = 23 into (2)

6x + 2y = 232 (2)

6(23) + 2y = 232

138 + 2y = 232

2y = 232 - 138

2y = 94

y = 94/2

= 47

y = 47

Answer:

A,F,J

Step-by-step explanation:

they are in simplified form and in the correct order

Given:

[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].

To find:

The quadrant.

Solution:

We know that,

In I quadrant, all trigonometric ratios are positive.

In II quadrant, only [tex]\sin \theta, \text{cosec}\theta[/tex] are positive and others are negative.

In III quadrant, only [tex]\cot \theta, \tan\theta[/tex] are positive and others are negative.

In IV quadrant, only [tex]\cos \theta, \sec\theta[/tex] are positive and others are negative.

We have,

[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].

Here, [tex]\tan \theta[/tex] is positive and [tex]\sec \theta[/tex] is negative. So, [tex]\theta [/tex] lies in the III quadrant.

Therefore, the correct option is C, i.e., III.

Answer:

A. (2,0)

Step-by-step explanation:

If you graph both of these equations, the two lines will intercept at point (2,0)

Answer:

Step-by-step explanation:

No because √2 and 3i come in pairs. The four roots are ±√2, 3i and -3i. The 5 guarantees that there are at least 5 roots to this equation. This is a good question to know the answer to. It looks like something that could be put on a test.

Answer:

infinite

Step-by-step explanation:

y and x can be any numbers because they're independants

Answer:

[tex]\infty[/tex]

Step-by-step explanation:

The domain/range of [tex]x[/tex] or [tex]y[/tex] is not restricted. Therefore, for [tex]x \in \mathrm{R}[/tex], the solutions for [tex]y[/tex] are [tex]\mathrm{R}[/tex] (all real numbers).

Therefore, there are an infinite number of solutions to this equation.

Answer:

x=10/7

Let's solve your equation step-by-step

6x−1=−x+9

Step 1: Add x to both sides

6x−1+x=−x+9+x

7x−1=9

Step 2: Add 1 to both sides

7x−1+1=9+1

7x=10

Step 3: Divide both sides by 7

7x/7=10/7

x=10/7

Answer:

x = 10 / 7

Step-by-step explanation:

6x - 1 = -x + 9

Add 1 to both sides of the equation.

6x - 1 = -x + 9

6x - 1 + 1 = -x + 9 + 1

Simplify

Add the numbers

6x - 1 + 1 = -x + 9 + 1

6x = -x + 9 + 1

Add the numbers

6x = -x + 9 + 1

6x = -x + 10

Add x to both sides of the equation.

6x = -x + 10

6x + x = -x + 10 + x

Simplify

Combine like terms

6x + x = -x + 10 + x

7x = -x + 10 + x

Combine like terms

7x = -x + 10 + x

7x = 10

Divide both sides of the equation by the same term

7x = 10

7x/7 = 10/7

Simplify

Cancel terms that are in both the numerator and denominator.

7x/7 = 10/7

x = 10/7

Solution

x = 10/7

Answer:

(c) y = 2x - 5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

1a) 67.2 kg

1b) 66.5 kg

1c) 64 kg, 68 kg

2a) Mean = 58.1m, Median = 55m, Mode = 49m

2b) The mode is not a good measure since all data except 49m appeared twice i.e. the data set is quite distributed. (sorry I am not very sure with this answer)

3a) Independent variable is time, Dependent variable is distance.

3b) See attachment.

3c) Linear

3d) 2.5s: 10m 6.25s: 25m 8s: 32m

3e) 3m: 0.75s 21m: 5.25s. 36m: 9s.

Step-by-step explanation:

1a) Mean = (74+71+68+84+54+60+64+68+65+64)/10 kg = 67.2 kg

1b) Sort the data in ascending order (in kg).

54 60 64 64 65 68 68 71 74 84

Median = (65+68)/2 kg = 66.5 kg

1c) Mode = 64 kg, 68 kg (both appeared twice)

2a) Mean = (45+52+47+55+62+80+71+60+84+57+46+50+48+61+49+63+54+49+72)/19 m =  58.1m (correct to 1 decimal place)

Arrange the data in ascending order (in m).

45 46 47 48 49 49 50 52 54 55 57 60 61 62 63 71 72 80 84

Median = 55m

Mode = 49m (appeared twice)

2b) See answer.

3a) Independent variable is the variable that is to be changed. Dependent variable is the variable that is to be measured.

3b) Just plot the graph.

3c) Distance = 4 x time

3d) 2.5 x 4 = 10m. 6.25 x 4 = 25m. 8 x 4 = 32m.

3e) 3/4=0.75s. 21/4=5.25s. 36/4=9s.

Answer:

Angle 4 is greater, it looks like is a 90 degree angle. so I will say is angle 4

Answer:

a

Step-by-step explanation:

its indirect cause the direct variation would be the y getting bigger with the x, but it's not. It's getting lower when the x is getting higher. hope this helps.

Answer:

I think it's A I'm not sure

Answer:

u = -24/7

Step-by-step explanation:

u = 6 = u

v      -7     4

-7u = 24

u = -24/7

Answer:

u = - [tex]\frac{24}{7}[/tex]

Step-by-step explanation:

Given that u varies directly with v then the equation relating them is

u = kv ← k is the constant of variation

To find k use the condition u = 6 when v = - 7, then

6 = - 7k ( divide both sides by - 7 )

- [tex]\frac{6}{7}[/tex] = k

u = - [tex]\frac{6}{7}[/tex] v ← equation of variation

When v = 4 , then

u = - [tex]\frac{6}{7}[/tex] × 4 = - [tex]\frac{24}{7}[/tex]

Answer:

6 days

Step-by-step explanation:

Given

The proportion can be represented as:

[tex]p = 55\%[/tex]

And the number of days can be represented as:

[tex]n = 10[/tex]

Required

Determine the expected number of times, the light is red

To do this, we simply multiply the proportion by the number of days:

[tex]Y = n * p[/tex]

Substitute values for n and p

[tex]Y = 10 * 55\%[/tex]

Convert percentage to decimal

[tex]Y = 10 * 0.55[/tex]

[tex]Y = 5.5[/tex]

Approximate

[tex]Y = 6[/tex]

Hence, the expected number of days is 6 days

Answer:

17 degrees because 180-163=17

Step-by-step explanation:

let the picture be named as above picture:

angle D +163=180 (linear pair)

D=180-163

D=17⁰

Sum of exterior angle of polygon is 360⁰.

148+50+17+90+angleC=360

198+107+angleC=360

305+angleC=360

angleC=360-305

angleC=55⁰

Answer: B is the answer

Answer:

Neither is a solution

Step-by-step explanation:

When you plug 3 as the x-value into the equation you get

3+7>12

10>12

This is false

When you plug 4 as the x-value into the equation you get

x+7>12

4+7>12

11>12

This is also false

Therefore neither is a solution

Hope it helped :))

Answer:

y = 1 3 x + 13 3

Step-by-step explanation:

The equation of the line is  

y = 1 3 x + 13 3

. To find other points on the line, simply plug in an x value, and solve for the corresponding y value.

Explanation:

To find other points on the line, we first have to find the equation for the line. We can easily use point-slope form:  

y − y 1 = m ( x − x 1 )

y − 5 = 1 3 ( x 2 )

To put it in slope-intercept form, isolate y and simplify:

y= 1 3 ( x − 2 ) + 5

y = 1 3 x − 23 + 5

y = 1 3 x + 13 3
