(2+2)^2=2^2∙2^2 true or false

Answer:

-6

Step-by-step explanation:

Answer:

Step-by-step explanation:

5x - 16 = 4x + 6

x - 16 = 6

x = 22

5(22) - 16 = 110 - 16 = 94

4(22) + 6 = 88 + 6 = 94

Answer:

30

Step-by-step explanation:

JL comprises of JK & KL. So ,

JL = JK + KL

Here the length of :-

KL= 9x + 3

JL = 55

JK = 7x + 4

So putting all the values above gives ,

7x + 4 + 9x + 3 = 55

=> 16x + 7 = 55

=> 16x = 55 - 7

= 48

=> x = 48/16 = 3

Using the value of x in finding the length of KL ,

KL = 9 × 3 + 3 = 27 + 3 = 30

Answer:

It's 0.61

Step-by-step explanation:

I graphed the equation and got 0.61 on the x axis when the y value was 1.24

The missing x-coordinate is 9.5. The correct answer is option D.

A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

The given function [tex]y = 2 -\sqrt{x+1}[/tex] and the point are ( x, -1.24 ). Put y = -1.24 in the given equation to get the value of x.

[tex]y = 2 -\sqrt{x+1}[/tex]

[tex]-1.24 = 2 - \sqrt{x+1}\\-1.24 - 2 = \sqrt{x+1}\\-3.24 = \sqrt{x+1}[/tex]

Squaring on both sides.

[tex](-3.24)^2 = (\sqrt{x+1})^2[/tex]

10.5 = x + 1

x = 9.5

Hence, the correct option is D.

We have proved that m∠ABC is an obtuse angle.

m∠ABC = m∠ABD + m∠DBC

100° = 60° + 40°

Given,

m∠ABD = 60°

m∠DBC = 40°

We need to prove that m∠ABC is an obtuse angle.

The angles greater than 90 degrees but less than 180 degrees are called obtuse angles.

We have,

From the figure.

m∠ABD = 60°

m∠DBC = 40°

We see that

m∠ABC = m∠ABD + m∠DBC

m∠ABC = 60° + 40°

m∠ABC = 100°

m∠ABC is greater than 90 degrees and less than 180 degrees so,

m∠ABC is an obtuse angle.

Thus we have proved that m∠ABC is an obtuse angle.

Answer:

-2 (6x - y) = -12x + 2y

Step-by-step explanation:

By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y

Answer:

0.488

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Here, n = 3 and p = 0.2.

The complement of at least 1 is at most 0.

P(r ≥ 1) = 1 − P(r = 0)

P(r ≥ 1) = 1 − ₃C₀ (0.2)⁰ (0.8)³⁻⁰

P(r ≥ 1) = 1 − (0.8)³

P(r ≥ 1) = 0.488

The addition is one of the four fundamental mathematical operations. Blair's bank balance after spending at the grocery store is -$70.

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Given that Blair's bank account was overdrawn by $40. Therefore, we can write her balance before spending at the grocery store as,

Blair's bank balance before spending at the grocery store = - $40

Now, Blair spent $30 at the grocery store. Therefore, she further takes $30 from her account. Thus, we can write Blair's bank balance after spending at the grocery store as,

Blair's bank balance after spending at the grocery store

= Blair's bank balance before spending at the grocery store + Spending

= -$40 + (-$30)

= -$40 - $30

= -$70

Hence, Blair's bank balance after spending at the grocery store is -$70.

Step-by-step explanation:

Answer:

[tex](-4, -1)[/tex]

Step-by-step explanation:

[tex]6x-y=-23[/tex]

Add y to both sides:

[tex]6x-y+y=-23+y\\6x=-23+y[/tex]

Divide both sides by 6:

[tex]\frac{6x}{6}=-\frac{23}{6}+\frac{y}{6}\\x=\frac{-23+y}{6}[/tex]

Substitute this into the second equation given:

[tex]2*\frac{-23+y}{6}+5y=-13[/tex]

[tex]\frac{-23+16y}{3}=-13[/tex]

Multiply both sides by 3:

[tex]-23+16y=-39[/tex]

Add 23 to both sides:

[tex]-23+16y+23=-39+23\\16y=-16[/tex]

Divide both sides by 16:

[tex]\frac{16y}{16}=\frac{-16}{16}\\y=-1[/tex]

We know that [tex]x=\frac{-23+y}{6}[/tex].

Thus, [tex]x=\frac{-23-1}{6}[/tex]

[tex]x=-4[/tex]

[tex](x, y) = (-4, -1)[/tex]

Answer:

Step-by-step explanation:

Rate X Time = distance

Therefore:

    r (rate) X 5 (hours) = 600 (distance)

    r = 600/5

    r = 120 miles per hour

    The rate of speed of the jet is 120 mph.

Then, to find out the distance flown in 13 hours:

    120 (rate) X 13 (time) = d (distance)

    120 X 13 = d

    1560 = d

    The distance flown in 13 hours is 1560 miles.

Jennie earned $300

Step-by-step explanation:

We are already given the amount of time that she works and the rate. We just need to multiply the time by the corresponding rate. She worked 22 regular hours and gets $10 for each one. That means she earned $220 just from the regular hours.

Now we need to add the overtime hours. She worked 4 hours and made $20 for each one. In total, that's $80.

220+80=300
