Which equations are true for x = -2 and x = 2? Select two options
Ox²-4 = 0
0x²= -4
3x² + 12 = 0
14x² = 16
2(x-2)² = 0

Answers

Answer:

x2-4 = 0

x2= 4

x = 2 or x = (-2)

The equations that are true for x = -2 and x = 2 are:

x² - 4 = 0

2(x - 2)² = 0

Options A and D are the correct answer.

What is a solution?

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We also find the solution in a system of equations using the substitution or elimination method.

Example:

2x + 4 = 8

The solution is x = 2.

We have,

The values given for x are -2 and 2.

Therefore, we can substitute each value of x into the given equations to determine which are true for those values.

x² - 4 = 0

When x = -2, we have (-2)² - 4 = 0, which is true.

When x = 2, we have (2)² - 4 = 0, which is also true.

x² = -4

When x = -2, we have (-2)² = 4 which is not equal to -4, so this equation is false for x = -2.

When x = 2, we have (2)² = 4 which is not equal to -4, so this equation is false for x = 2.

3x² + 12 = 0

When x = -2, we have 3(-2)² + 12 = 0, which is false.

When x = 2, we have 3(2)² + 12 = 24, which is not equal to 0.

Therefore, this equation is false for x = 2.

14x² = 16

When x = -2, we have 14(-2)² = 56, which is not equal to 16.

Therefore, this equation is false for x = -2.

When x = 2, we have 14(2)² = 56, which is also not equal to 16.

Therefore, this equation is false for x = 2.

2(x-2)² = 0

When x = -2, we have 2(-2-2)² = 0, which is not equal to 0.

Therefore, this equation is false for x = -2.

When x = 2, we have 2(2-2)² = 0, which is equal to 0.

Therefore, this equation is true for x = 2.

Therefore,

The equations that are true for x = -2 and x = 2 are:

x² - 4 = 0

2(x-2)² = 0

Two fire trucks on the ground on either side of a burning building or 1.3 miles apart. they each measure the angle of elevation to the fire which are 58° and 52°. How far is each truck from the fire? Please help ASAP thank you so much!

Answers

The distance of the first truck from the fire is 0.578 mile and the distance of the second truck from fire is 0.722 mile.

Distance of each truck from the fire

Using sine rule, we find the length of AB and BC as shown in the image.

a/sin A = b/sin B = c/sin C

Angle C = 180 - (58 + 52) = 70⁰

1.3/(sin 70) = b/(sin 52)

b = (1.3sin 52) / (sin 70)

b = 1.09 mile

c = (1.3sin 58) / (sin 70)

c = 1.1732 miles

Bisect angle C, and use sine rule again to find the lengths of bisected line AB.

1.09/(sin 90) = x/[sin (90 - 58)]

1.09/(sin 90) = x/(sin 32)

x = (1.09 sin 32)/(sin 90)

x = 0.578 mile

Truck B's position from the fire = 1.3 miles - 0.578 mile = 0.722 mile

Based on this information, you are required to perform the following; a) what percetage(to 3 decimals) of the students scored more than 78? B) what percentage of the students to 3 decimal places scored under 50? And c) what percentage to 3 decimal places of the students scored between 60 and 80?

Answers

Answer:

Step-by-step explanation:

The Final grades follows normal distribution.

It means =70

The Given standard deviation =10

The normal random variable of a standard normal distribution is called a standard score or a z-score. In Every normal condition, random variable X will be transformed into a z score via the following equation:

z=(X)

But when X is a normal random variable, μ is the mean of X.

For That, it is X=60

Z=(60−70)/10=−1

P(X<60)=P(Z<−1)

Lily pads increase by 25% every 10 days.lf a pond starts with 22 lily pads,how many will there be after 50 days?

Answers

We conclude that after 50 days, there will be 67 lily pads.

how many will there be after 50 days?

We know that the number increases by 25% every 10 days.

In 50 days we have 5 groups of 10 days, so there will be five increases of 25%.

We know that the initial number is 22 lily pads, if we apply five consecutive increases of the 25% we get:

N = 22*(1 + 25%/100)*...*(1 + 25%/100%)

( the factor (1 + 25%/100%) appears five times)

So we can rewrite:

N = 22*(1 + 25%/100%)⁵

N = 22*(1 + 0.25)⁵ = 67.1

Which can be rounded to the nearest whole number, which is 67.

So we conclude that after 50 days, there will be 67 lily pads.

Answers

The difference in price between the two companies is $81-$79.56 = $1.44

Fire side Shop

Price of Chimney cap =$120

First Discount = 25% of(120)=$30

Price after 1st Discount = $120-$30=$90

Second Discount = 10% of 90=$9

Price after 2nd Discount = $90-$9=$81

Builders' Supply

Price of Chimney Cap= $111

First Discount= 25% of 111 = $27.75

Price after 1st Discount = $111 - $27.75 = $83.75

Second Discount = 5% of $83.75 = $ 4.1875

Price after 2nd Discount = $83.75 - $4.1875 = $79.5625 ≈ $79.56

Given equations are,

9x+8y=26 .................(1)

3x+2y=9 ...................(2)

Now multiplying 3 with (2) and then subtracting (1) from that we get,

Reason
We know he exercised for 2 days
We know the second day was -20
We know the total minutes = 150
We don’t know x

Equation is 2x -20 = 150. Solve for x
Isolate x by subtracting (-20) from both sides.
2x = 170. Solve for x by dividing both sides by 2.

line / is parallel to line m. the slope of line / is 4/9. what is the slope of line m?

Answers

Answer: 4/9

Step-by-step explanation:

Parallel lines have equivalent slopes.

As line 'l' and line 'm' are parallel to each other ,then the slope of line 'm' is also 4/9.

Parallel lines have the same slope. The slope of line segments is identical because they are all similarly inclined with respect to the positive x-axis. If 'l', and 'm' are the slopes of two parallel lines,

then l = m

Slope-intercept notation for lines may be expressed as y=mx+b.

In this notation, b denotes the location of the line's y-axis intercept, and slope(m) indicates the slope of the line.

The slope of 'l'=4/9

The slope of the two parallel lines is the same.

Therefore, the slope of the parallel line "m" = 4/9.
