Use the graphing tool to graph the system.

Answer:

y = -1/3 x + 5

Step-by-step explanation:

The general equation is y = mx + b

You are told that the y intercept is 5. The point is (0,5)

So far the general equation looks like y = mx + 5

Now we have to find m

The given slope of y = 3x + 2 is 3.

The slope is whatever number is in front of the x

Use this formula for the vertical slope

m * m1 = - 1

m1 = 3

3*m = - 1                                     Divide by 3

m = -1/3

So the answer you want is y = -1/3 x + 5

- remember that the midline is always half of the sum of the other two legs.

here,

UX is the midline,

ST is the leg,

VW is the other leg.

so,

ST + VW = 2UX

now plug in,

25 + VW = 2(35)

25 + VW = 70

VW = 45

Step-by-step explanation:

Consecutive Exteriour Angles form a linear pair, so you set them equal to [tex]\displaystyle 180°:[/tex]

[tex]\displaystyle 180° = 110° + m∠4; 70° = m∠4[/tex]

Answer: 17 years

Step-by-step explanation:

City A is currently 2,425 people in number and growing at 27 per year.

An expression to find the population in a given year assuming the year is x would be:

= 2,425 + 27 * x

= 2,425 + 27x

Applying the same logic to City B would give an expression of:

= 1,813 + 63x

Equating these together will give the year they will be the same:

2,425 + 27x = 1,813 + 63x

2,425 - 1,813 = 63x - 27x

612 = 36x

x = 612/36

x = 17 years

Answer:

Daniel is rollerblading at 15 miles per hour

Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15

Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

c) Q( 5, -2) , S(-3,4)

P( 5,2) → Q( 5, -2)

Q(-3,-4)→ S(-3,4))

Step-by-step explanation:

Explanation:-

Given points are  P( 5,2) and Q(-3,-4)

Points P and R   reflection  across the x-axis then the co-ordinate point is transformed to  (x,y)→ (x,-y)

P( 5,2) → Q( 5, -2)

Q(-3,-4)→ S(-3,-(-4))

Q(-3,-4)→ S(-3,4))

Answer:

Length=10 feet

Width=6 feet

Step-by-step explanation:

Let width (W) of the garden is x feet

Then Length=L=4+x feet

Perimeter=P=2(W + L)

P=2(x+x+4)

32=4x+8

4x=32-8

x=24/4=6 feet

W=6 feet

L=10 feet

Answer:

Option (3)

Step-by-step explanation:

Let the unknown angle of the triangle measure x°.

By applying cosine rule in the right triangle,

cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(x) = [tex]\frac{33}{65}[/tex]

x = [tex]\text{cos}^{-1}(\frac{33}{65})[/tex]

x = 59.49°

  ≈ 60°

Therefore, option (3) will be the correct option.

hope it helps :)

The angle ∠JIL and ∠HIL are supplementary angles. Then the correct option is D.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

HJ and KM are parallel lines. And NG interset the line HJ at I and KM at L.

Then the supplementary angles are given below.

∠JIL and ∠HIL

The angle ∠JIL and ∠HIL are supplementary angles. Then the correct option is D.

Step-by-step explanation:

In mathematics a when dealing with graphs a translation is basically just moving points left/right and up/down but it does not change the shape of the original figure in any way just moves its position. In this scenario, the down arrow's tip will be moved from point (2,0) to (-3,1) but the arrow will still be the same size and still be pointing downward.

[tex]y= 480-0.5x[/tex]

Step-by-step explanation:

Given data

Number of balls= 480

we are told that 50%(half) of the balls are put back every 1

let the number of hours be x

and let the remaining ball be y after x hours

Hence the expression is given as

[tex]y= 480-0.5x[/tex]

Answer:

The length of QS = 8

Step-by-step explanation:

From the above question:

Δ Q R S ≅ Δ T U V

Q S = 3 v + 2 , and T V = 7 v − 6 , enter the lengths of QS

Hence:

Step 1

We solve for v

QS = TV

3v + 2 = 7v - 6

Collect like ters

2 + 6 = 7v - 3v

8 = 4v

v = 8/4

v = 2

Step 2

Solving for Q S

Q S = 3 v + 2

v = 2

QS = 3(2) + 2

QS = 6 + 2

QS = 8

The length of QS = 8

Answer:

16

Step-by-step explanation:

let the smaller no be x so the greater no is 8 + x

soln

8+x + x = 40

8 + 2x = 40

2x = 40-8

2x = 32

x = 32÷2

therefore x = 16

Answer:

16 and 24

Step-by-step explanation:

let the 2 numbers be x and y, x > y , then

x + y = 40 → (1)

x = y + 8 → (2) [ greater number 8 more than smaller ]

Substitute x = y + 8 into (1)

y + 8 + y = 40, that is

2y + 8 = 40 ( subtract 8 from both sides )

2y = 32 ( divide both sides by 2 )

y = 16

Substitute y = 16 into (2)

x = 16 + 8 = 24

The 2 numbers are 16 and 24

Answer:

The value of [tex]\frac{1}{2}y[/tex] is -1

Step-by-step explanation:

Equations

We have the equation:

[tex]-3(y - 1) = 9[/tex]

It's required to find

[tex]\frac{1}{2}y[/tex]

Let's solve the equation. Dividing by -3:

[tex]y - 1 = \frac{9}{-3}= -3[/tex]

Adding 1:

[tex]y=-3+1=-2[/tex]

Since y=-2, then y/2=-1

The value of [tex]\frac{1}{2}y[/tex] is -1
