What is the equation of the line that contains the point (-1, 4) and has a slope of 3?
sertanlavr [38]

Let's write the equation with formula:-

\boxed{ \sf \: formula : y -y_{1} =  m(x -  x_{1})}

Where,

  • x1 is -1 and y1 is 4 and m is 3

\tt \: y - 4= 3(x - ( - 1))

\tt \: y  - 4 = 3(x + 1)

\tt \: y  - 4 = 3x + 3

\tt \: y = 3x + 3 + 4

\tt \: y = 3x + 7

<em>Thus, The correct choice is option C!!~</em>

<u>Correct </u><u>Inputs </u><u>:-</u>

In ΔABC right angled at A, D and E are points on BC, C such that BD = CD and AD ⊥ BC

\underline{\underline{\large\bf{Solution:-}}}\\

\longrightarrow Let us know about definition of altitude first. The altitude of a triangle is the perpendicular line segment drawn from the vertex to the opposite side of the triangle.

\leadstoMedian is the line segment from a vertex to the midpoint of the opposite side.

<u>Let us Check all options one by one </u>

  • CD is line segment which starts from vertex C but don't falls on opposite side AB thus it is not an altitude.❌

  • BA is line segment which starts from vertex B and falls perpendicularly on opposite sides AC and is thus an altitude.✔️

  • AD is line segment which starts from vertex A and falls perpendicularly on opposite side BC and is thus an altitude.✔️

  • AE is a line segment which starts from vertex A but doesn't falls perpendicularly on opposite side BC and is thus not an altitude.❌

  • AD falls on BC with D as mid point because BD = CD and is thus a median. ✔️

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue , 1 red , and 1 orange sectio
erik [133]

Hey there!

\large\boxed{25\%}

Assuming that all the sections are the same size, there are four sections of equal size.

Blue would be one out of those four sections, so the probability is 1/4. In decimal form this is .25, and as a percent this is 25%.

Hope this helps!

A grocer sells milk chocolate at $2.90 per pound, dark chocolate at $4.90 per pound, and dark chocolate with almonds at $5.50 pe
daser333 [38]

Answer: milk chocolate = 10 pounds

Dark chocolate =15 pounds

Dark chocolate with almonds = 25 pounds.

Step-by-step explanation:

What we have here is a proportion problem.

Milk chocolate = $2.90

Dark chocolate = $4.90

Dark chocolate with almonds = $5.50

We are to have 50 pounds of mixed chocolate

Amount the grocer makes from this

= $4.80 × 50 = $240

However, we must consider how much the grocer would have made if he had sold them separately

Weight of milk chocolate = x

Weight of dark chocolate = y

Weight of dark chocolate with almond = z

x+y = z (according to the question)

x+y+z= 50

Equating the collective amount of each type of chocolate with the amount they all cost together

2.90x + 4.90y + 5.50z = 50(4.80)

2.90x + 4.90y + 5.50z = $240

But z = x + y

2.90x + 4.90y + 5.50 (x+y) = $240

2.90x + 4.90y + 5.50x + 5.50y = 240

8.40x + 10.40y = 240 .....eqn 1

Since x + y + z = 50

x + y = 50 - z

But x+ y = z

x + y = 50 - (x+y)

x + y = 50 - x - y

2x + 2y = 50

(Divide through by 2)

x+y = 25 ...... Eqn 2

y = 25 - x

Substitute for y in eqn2

8.4x + 10.4 (25-x) = 240

8.4x + 260 - 10.4x = 240

8.4x - 10.4x = 240 - 260

-2x = -20

x = 10 pounds

y = 25-x

y = 25-10

y=15pounds

x+y+z= 50

10+15+z= 50

25+z=50

z= 50-25

z = 25
