Answer:

Slide 1 answer:B: p=-6

Slide 2 answer : C: x=0

Slide 3 answer: A: a=0

Step-by-step explanation:

You can do this two ways.

Way 1: plug in that answer choices to your equation and see if one of them makes the equation true

Way 2: isolate varable and do sadmep... reverse operations.

I will use anyone that best suits you but i will use way 2.

5p-14=8p+4

move 5p by subtracting on both sides

-14=8p-5p+4

-14=3p+4

now subtract 4 from both sides

-14-4=3p

-18=3p

now divide 3 on both sides to isolate p

-18/3=p

p=-6

Slide 2:

for this one i will just plug in answers to see which one makes the statement correct

12=-4(-6(1)-3)

12=-4(-6-3)

12=-4(-9)

i already know its incorrect because -4*-9 is a way higher number then 12

so x=1 is incorrect

lets try x=0

12=-4(-6(0)-3)

12-4=(-6*0=0 -3)

12=-4(-3)

12=12

so x=0 is correct

Slide 3:

For this one as well i will plug in the answers to see which one makes the statement true.

a=0

0+5=-5(0)+5

5=5

this statment is true so

a=0 is correct

Answer:

-1/2

Step-by-step explanation:

$x_{1}=-7 \ ; \ y_{1}=-4\\\\x_{2}=-11 \ ; \ y_{2} = -2\\\\\\Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\dfrac{-2-[-4]}{-11-[-7]}\\\\\\=\dfrac{-2+4}{-11+7}\\\\\\=\dfrac{2}{-4}\\\\\\=\dfrac{-1}{2}$

ss7ja [257]

Answer:

Samantha worked 12 hours and Amy worked 7 hours.

Step-by-step explanation:

Samantha worked 12 hours, so Amy is 5 less, so Amy would be 7 hours. 12+7 = 19.

you roll a six sided dice 60 times the number for which the experimental probability of rolling the number is the same as the th

ziro4ka [17]

Answer:

The answer is "12 times, a die was rolled. Identify the complete possibilities to roll exactly 6".

Step-by-step explanation:

Using formula:

$P(X=K)=\binom{N}{K} P^{K} a^{N-K}$

So the value is $P(X=6)$

HELP PLEASE find the x-intercepts of the parabola with vertex -1,-17 and y-intercept 0,-13. Write your answer in this form: (x1,

Rzqust [24]

Answer:

(1.06, 0), (-3.06, 0)

Step-by-step explanation:

Substitute the vertex (-1, -17) and the point (0, -13) into the vertex form of a parabola: y = a(x - h)^2 + k. Solve for a.

-13 = a(0 - (-1))^2 - 17

Simplify this equation.

-13 = a(1)^2 - 17

Evaluate the exponent.

-13 = a - 17

Add 17 to both sides.

4 = a

Now substitute the vertex and the a-value into the vertex form of a parabola: y = a(x - h)^2 + k.

y = 4(x - (-1))^2 - 17

Simplify.

y = 4(x + 1)^2 - 17

Now to find the x-intercepts, make y = 0.

4(x + 1)^2 - 17 = 0

Add 17 to both sides.

4(x + 1)^2 = 17

Square root both sides.

2(x + 1) = $\pm\sqrt{17}$

Divide both sides by 2.

x + 1 = $-1\pm\frac{\sqrt{17}}{2}$

Subtract 1 from both sides.

x = $\left \{ {{-1+\frac{\sqrt{17}}{2} ~= ~1.06} \atop {-1-\frac{\sqrt{17}}{2}~=~-3.06}} \right.$

Since you want the answers in the form (x1, y1), (x2, y2) and for the answers to be rounded to the nearest hundredth, your final answers are:

(1.06, 0), (-3.06, 0)
