Answer:

A) x+4y=13

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-4)/(5-(-3))

m=-2/(5+3)

m=-2/8

simplify

m=-1/4

y-y1=m(x-x1)

y-4=-1/4(x-(-3))

y-4=-1/4(x+3)

y=-1/4x-3/4+4

y=-1/4x-3/4+16/4

y=-1/4x+13/4

y-(-1/4x)=13/4

y+1/4x=13/4

4(y+1/4x)=4(13/4)

4y+4/4x=13

4y+x=13

x+4y=13

Answer:

54 degrees

but i think its 63 degrees now

Step-by-step explanation:

because i think this is an equilateral triangle

edit

wait i think its actually 63 because a triangle is 180 degrees and when you add..

54 + 63 + 63 = 180

Answer:

D. 63°

Step-by-step explanation:

sum of angles in a triangle = 180°

therefore

y + y + 54 = 180

2y + 54 = 180

2y = 126

y = 63°

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

From the given data we will form an equation

Ayshab walked x miles at 4 mph. She then walked 2x miles at 3 mph. The second part of the journey took 25 minutes longer than the first part of the journey

2x/3    =   x/4  +  5/12

2x/ 3   =    3x/12   +   5/12

2x/3    =    3x   +  5/2

24x     =    9x   +  5

15x     =    15

X     =     1

25 minutes/60    =     5/12

Therefore the value of x will be equal to 5 / 12 for the given equation.

Step-by-step explanation:

Answer:

Jack and Jill would each be [tex]200\; {\rm ft}[/tex] away from the trail guide.

Step-by-step explanation:

Refer to the diagram attached. Let [tex]\sf A[/tex] denote Jack, [tex]\sf I[/tex] denote Jill, and [tex]\sf G[/tex] denote the trail guide.

The angle [tex]\angle {\sf GAI} = 60^{\circ}[/tex] as it represents the depression angle of the trail guide from the perspective Jack. Likewise, [tex]\angle {\sf GIA} = 60^{\circ}[/tex] for the angle from the perspective of Jill.

Note that in triangle [tex]\triangle {\sf AGI}[/tex]:

[tex]\begin{aligned}\angle {\sf AGI} &= 180^{\circ} - \angle {\sf GAI} - \angle {\sf GIA}\\ &= 180^{\circ} - 60^{\circ} - 60^{\circ} \\ &= 60^{\circ} \end{aligned}[/tex].

Thus, triangle [tex]\triangle {\sf AGI}[/tex] would be an equilateral triangle as all its interior angles are  [tex]60^{\circ}[/tex]. Therefore, the length of all three sides would be equal:

[tex]\overline {\sf AG} = \overline{\sf GI} = \overline{\sf AI}[/tex].

The length of segment [tex]\sf{AI}[/tex] represents the distance between Jack and Jill. This distance is supposed to be the same as the width of the canyon,  [tex]200\; {\rm ft}[/tex]. Thus, [tex]\overline{\sf AI} = 200\; {\rm ft}[/tex].

The distance between Jack and the trail guide would be the same as the length of segment [tex]{\sf AG}[/tex], which is [tex]\overline{\sf{AG}} = \overline{\sf AI} = 200\; {\rm ft}[/tex].

Similarly, the distance between Jill and the trail guide would be the same as the length of segment [tex]{\sf GI}[/tex], which is [tex]\overline{\sf{GI}} = \overline{\sf AI} = 200\; {\rm ft}[/tex].

The calories in a cup of low fat milk is 102 calories and the  calories in a cup of milk in skim 86 calories .

2/3l + 1/2s = 111

4l + 3s = 666 equation 1

l + s = 188 equation 2

Where:

l = calories in the low fat milk

s = calories in the skim milk

Multiply equation 2 by 4

4l + 4s = 752 equation 3

Subtract equation 1 from 3

s = 86

Substitute for s in equation 2

l + 86 = 188

l = 188 - 86

True, the three sides will form exactly one unique triangle.

A triangle is three dimensional shape, whose third length is less than the sum of the first and second length.

(b - a) < k < (b + a)

(6.3 cm - 5.2 cm) < k (6.3 cm + 5.2 cm)

1.1 cm < k < 11.5 cm

The third length = 10.5 cm which is greater than 1.1 cm and less than 11.5 cm.

Thus, the three sides will form exactly one unique triangle.

Melanie should take A and B, being r(loan a)= 9.699% annually, r(loan b)=9.862% annual

It is given that

Loan A: 9.265% nominal rate, compounded weekly

In order to find the easiest effective rate, we need to divide this rate by 52 (which are the weeks in a year). Once we do that, we convert this effective weekly rate into an effective annual rate. Let´s walk you through all this.

[tex]r(Eweek)=\dfrac{0.09265}{52} =0.00178173[/tex]

Or 0.178173% effective weekly. Now we can transform it into an effective annual rate.

[tex]r(e,a)=1+(r(e.week))^{52} -1[/tex]

[tex]r(e,a)=1+(0.00178173)^{52} -1=0.09699[/tex]

Or 9.669% annual, which is less than 9.955%, so this one is selected, let´s check the next.

Loan B: 9.442% nominal rate, compounded monthly

Just like we did with Loan A, we need to divide this rate too, only this time, we will divide by 12, therefore obtaining an effective monthly rate.

[tex]r(Emonth)=\dfrac{0.09442}{12} =0.00786833[/tex]

Or 0.786833% effective monthly, let´s turn it into an effective annual rate.

[tex]r(e,a)=1+(r(e.month))^{12} -1[/tex]

[tex]r(e,a)=1+(0.00786833))^{12} -1=0.09862[/tex]

Or 9.862% annual, so this rate would work for Melanie too. This means that option C) is the answer we are looking for but, let´s walk that extra mile and turn that Loan C rate into an annual rate.

[tex]r(Eweek)=\dfrac{0.09719}{4} =0.0242975[/tex]

or 2.42975% effective quarterly, now, let´s convert it into an effective annual rate.

[tex]r(e,a)=1+(0.0 242975))^{12} -1=0.010079[/tex]

That is 10.079% effective annual, therefore, Loan C is not an option for Melanie.

Thus Melanie should take A and B, being r(loan a)= 9.699% annually, r(loan b)=9.862% annual

Step-by-step explanation:

this is because that 1 in 5 is equal to 20%

Answer:

1. 3

2. -2

3. (1, 2)

Step-by-step explanation:

y axis is the numbered line that looks like the |

x axis is _

so the y int is 3 because A intercepts the y axis at 3

the y int for B is -2 because it intercepts the y axis at -2

the intersection of both lines is (1, 2) because you look and the point is at 1 for x and 2 for y

Answer:

y-intercept of line a: y=3

y-intercept of line b: y=-2

intersection: (1, 2)

Step-by-step explanation:

So the y-intercept of each line is where each line touches the y-axis.

The y-axis is the vertical line down the middle of the graph.

For line a, it touches the y-axis at 3, so we say the y-intercept is y=3.

For line b, it is the same thing, except it touched the y-axis at -2, so we say y=-2.

The intersection is the point at which both lines cross. In this graph, they cross the point (1, 2). Let me know if you need help figuring out how to do that.

Hope this helps!
