1) 4^3 - 3^4 = 64 - 81 = (-17)

2) 34.782467:
to nearest decimal point: 34.7
to nearest 4 significant figures: 34.78

3) 2x + 4 / 18
    x = 4
   (2)(4) + 4 / 18
   (8) + 4 / 18
   12 / 18
   0.66 (was rounded to  nearest decimal place)

Please mark my answer brainliest when you get the chance so that I can move up to my next rank. Thank you and have a nice night.

tom's and tim's ages add up to 21 years. In 3 years, Tom will be twice time's age. How old are they now?
Dafna11 [192]
X=Tom´s age
y=Tim´s age.
we suggest this system of equations: 

x+y=21
(x+3)=2(y+3)

We solve this system of equations by susbstitution method.
x=21-y
[(21-y)+3]=2(y+3)
24-y=2y+6
-y-2y=6-24
-3y=-18
y=-18/-3=6

x=21-y
x=21-6=15.

Answer: Tom is 15 years old, and Tim is 6 years old.

Which best describes the relationship between the line that passes through the points (-6,5) and (-
natita [175]

Answer:

Slope passes through (-6, 5) and (-2, 7)

m_1=\frac{y_2-y_1}{x_2-x_1} =m_1=\frac{7-5}{-2+6}

m_1=\frac{2}{4} =\frac{1}{2}

Slope passes through (4, 2) and (6, 6)

m_2=\frac{6-2}{6-4}

\frac{4}{2} =2

m_1\times m_2 \neq -1 m_1\neq m_2

<u>Answer:- A) neither perpendicular nor parallel.</u>

Please help me answer the question
Rufina [12.5K]

Answer:

y=-x+2

Step-by-step explanation:

The slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

From the graph, we can see that the y-intercept is at (0,2) so the equation becomes y=mx+2.

Other points on the graph include (1,1) and (2,0). Plugging (1,1) into the slope-intercept equation, we get 1=(m)1+2. Solving this will give us m=-1.

We can confirm this by plugging m=-1 into the equation along with the point (2,0); 0=(-1*2)+2. It checks out!

So our final equation in slope-intercept form will be y=-x+2

The product of two consecutive negative even integers is 24. Find the largest integer.
natali 33 [55]

Answer:

-4

Step-by-step explanation:

ok negative times negative = positive

and factors of 24 are

1,2,3,4,6,8,12,24

4 x 6 are the two consecutive EVEN numbers

so turn it to negative

-4 x -6 = 24

The largest is -4
