Answer:

y= -9x+14

Step-by-step explanation:

the equation of a straight line is y=mx+c

m is the slope

And we are given a y and x term

So we substitute these into the equation:

5= -9(1) + c

rearragne to find c

14= c

so the full equation is:

y= -9x+14

Answer:

The correct answers is letter C

Step-by-step explanation:

= x(1/6 + 2/5 - 8/3) + 42 - 19

= - 21/10x + 42 -19

= -21/10 x + 23

Multiply amount she saves per month by 5 months:

35 x 5 = $175

$175 is less than the price of the player so she won’t have enough to buy it.

197.99 - 175 = $22.99

She needs $22.99.more

Now, let's use Pythagoras theorem to find JK.

Option A is correct.

Answer:

The correct statement is each successful toss is worth 3 points.

It is a branch of mathematics that deals with the occurrence of a random event.

Players earn points for successful tosses and lose points for missed tosses.

Results for two players are shown in the table.

Number of successful toss, number of missed toss and total number of points for Player 1 and Player 2 are given in the table.

Let's assume that:

Each successful toss = +x points

Each missed toss = -y points

From the given table:

4x - 3y = 6 ...(i)

5x - 5y = 5

x - y = 1

y = x - 1

Substituting y in eq(i)

4x - 3(x - 1) = 6

4x - 3x + 3 = 6

x = 3 and y = 2

Hence, the correct statement is each successful toss is worth 3 points.

Check the image below the explanation.

Step-by-step explanation:

Answer:

h = 2[tex]\sqrt{3}[/tex]

b = 3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

to find 'h' we can use the ratio of sides in a 30-60-90° triangle which, respectively, is 1 : [tex]\sqrt{3}[/tex] : 2

so we can set up this proportion:

h/2 = 1/[tex]\sqrt{3}[/tex]

cross-multiply:

h = 2[tex]\sqrt{3}[/tex]

to find 'b' we can use the ratio of sides in a 45-45-90° triangle which, respectively, is 1 : 1 : [tex]\sqrt{2}[/tex]

we can set up this proportion:

3/b = 1/[tex]\sqrt{2}[/tex]

cross-multiply:

b = 3[tex]\sqrt{2}[/tex]

sinθ is equal to the division of the opposite side of the reference angle (θ) by the hypotenuse.

the cosine of an angle in a right triangle equals the adjacent side divided by the hypotenuse

sin45 = 3/b

Answer:

They are not equivalent

Step-by-step explanation:

[tex]{ \tt{ - 9h - 4.5 \equiv - 0.75(12h - 4.5)}} \\ \\ { \tt{ - 9h - 4.5≠( - 9h + 3.375)}}[/tex]

Answer:

No, they are not equivalent.

Step-by-step explanation:

So in order to solve this question, you need to set the equations equal to each other. -9h-4.5=-0.75(12h-4.5)

Let's work on the left side first, only because it's going to take more work and because we need to solve it in order to continue the process. So you first are going to want to use the distributive property. Multiply 12h and -4.5 by -0.75. 12h*-0.75=-9h. -4.5*-0.75=3.375. so now your equation looks like -9h-4.5=-9h+3.375

So just looking at it, it seems as if these equations are not equivalent, just parallel.

Hope this helps!

Answer:

June, July, and August.

Step-by-step explanation:

1600<2570-125.5x<2000  subtract 2570 from all terms...

-970<-125.5x<-570  divide all terms by -125.5 (and reverse signs because of division by a negative!)

7.73>x>4.54  and x is months since January, and since months can only be integers...

x=[5,7]

So January + 5, 6, and 7 respectively are the three months that satisfy the equation...

June, July, and August.

Answer:

A right-angled triangle has 2 legs and a hypotenuse.

In trigonometry, the 2 legs are labelled opposite and adjacent, and this labeling is interchangeable, depending on which interior angle we are working with.

the hypotenuse is always the side opposite to the 90° angle and is therefore always the longest side.  So for this triangle, the hypotenuse is line LM.

For example, If we look at angle L, the line KL is adjacent (next) to it, and line KM is opposite to it.  However, if we look at angle M, the line KM is adjacent to it, and the line KL is opposite it.  Remember, the hypotenuse doesn't change.

Therefore:

Angle adjacent to side KL = angle L

Angle adjacent to side KM = angle M

Side opposite to angle L = side KM

Side opposite to angle M = side KL

Hypotenuse = side LM

The formula for slope is:  m  =  (y2 - y1) / (x2 - x1)   --->   m  =  (b - b) / (-a - a)  =  0/(-2a)  =  0

Total = $14+$3+$4

Total = $21

Each friend owe = $21/3

So, each friend owe $7

Answer:

$7 each

Step-by-step explanation:

Let's determine the total cost first to see how the friends can divide the cost.

The total cost is $21. 14 for a pizza, 3 for the soda, and 4 for the cake.

There are 3 friends and 21 goes evenly in 3. So 21 divided by 3 is $7 per person.

Answer:

x = -2  ||   y = -3

Step-by-step explanation:

5x - 2y = -4

x + 2y = -8

--------------------------------------------

5x - 2y = -4

5x = -4 + 2y

x = (-4 + 2y)/5

x + 2y = -8

x = -8 - 2y

Solving simultaneously:

-8 - 2y  =   (-4 + 2y)/5

5(-8 - 2y) = -4 + 2y

-40 - 10y = -4 + 2y

-40 + 4 = 2y + 10y

-36 = 12y

y = -3

if y is -3 then x is:

x = -8 - 2y

x = -8 - 2(-3)

x = -2

∠ABD and ∠EBC are complementary by the definition of complementary angles.

Given that in a figure, BD ⊥ BC ; ∠ABD ≅ ∠DBE.

We need to prove ∠ABD and ∠EBC are complementary.

BD ⊥ BC = given

∠DBC = 90° by the definition of perpendiculars.

∠ABD ≅ ∠DBE = given

∴ ∠ABD = ∠DBE by the definition of congruence.

Using the angles addition postulate,

∠EBC + ∠DBE = 90°

Now, replace ∠DBE by ∠ABD, we get,

∠EBC + ∠ABD = 90°

Hence ∠ABD and ∠EBC are complementary by the definition of complementary angles.
