HELP ITS AN EMERGENCY

Mathematics
1 answer:
forsale [732]3 years ago
7 0

Answer:

<u>A. Vertex: (1, -8); x-intercepts: -1 and 3</u>

Step-by-step explanation:

The vertex is the point of the parabola. Basically, the part where the parabola 'scoops' up.

So the point where it scoops up is (1, -18)

The x-intercepts are the points where the line or shape touches the x-axis. The x-axis is the lines that goes from left to right.

The places where it touches the x-axis is -1 and 3

$668 at 9.25% for 5 years
madreJ [45]

Answer:

$21.17

Step-by-step explanation:

Simple Interest=P(1+r)^t

Compounded Interest=P(e^rt)

SI=668*(1.0925)^5

SI=1039.64

CI=668(e^(0.0925*5))

CI=1060.81

1060.81-1039.64=21.17

So the difference is $21.17, thus doing compounded interest is better.

Find the equation,in standard form, of the line passing through the point (2,-3) and (4,2)
VLD [36.1K]

The standard form:

Ax+By=C

The point-slope form:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (2, -3) and (4, 2). Substitute:

m=\dfrac{2-(-3)}{4-2}=\dfrac{5}{2}

y-(-3)=\dfrac{5}{2}(x-2)

y+3=\dfrac{5}{2}(x-2)       <em>use distributive property</em>

y+3=\dfrac{5}{2}x-5            <em>multiply both sides by 2</em>

2y+6=5x-10                     <em>subtract 6 from both sides</em>

2y=5x-16         <em>subtract 5x from both sides</em>

-5x+2y=-16          <em>change the signs</em>

\boxed{5x-2y=16}

HELP ITS ABOUT POINTS AND EQUATIONS AND WHAT THE PERSON FAILED IN DOING EXPLANATION NEEDED PLEASE
katen-ka-za [31]

Answer:

see below

Step-by-step explanation:

First find the slope

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

  = (-5- -7.5)/ ( 2 - -3)

  = (-5+7.5) / ( 2+3)

  = 2.5 /5

   =1/2

Then using the slope intercept equation of a line

y = mx+b where m is the slope and b is the y intercept

y = 1/2x+b

Using a point from above

-5 = 1/2(2) +b

-5 =1+b

Subtract 1 from each side

-6 = b

We have the y intercept

y = 1/2x-6

Tahlia forget to find the y intercept for the equation
