Answer:

B, E

Step-by-step explanation:

The function y=1.5+x has two points listed which make the equation true.

(-1.5,0)

y=1.5+x

0=1.5+-1.5

0=0

(4.5,6)

y=1.5+x

6=1.5+4.5

6=6

Answer:

Option A,D and F

Step-by-step explanation:

Given : Function y=1.5+\lceil x\rceil

To find : Which are points lie on the graph of given function?

Solution :          

To determine the points lie on the graph,

First we graphed the given function y=1.5+\lceil x\rceil

In the function, ⌈x⌉ means the ceiling of x, i.e. the smallest integer greater than or equal to x.

Refer the attached figure below.

Now, We mark all the points mention in question.

We note the point line on the ceiling x are A(-4.5, -2.5), D(1.3, 3.5) and F(7.9, 9.5).

Therefore, The required result is Option A,D and F.

Can someone please help me on e and f i dont understand it and pls explain

For parts A, B, C, and D you most likely created a line. What question E is asking is for you to create a line that is perpendicular to the line you already created that also passes through the point (1,1). What is important to understand here is that the slope of the perpendicular line is the negative reciprocal of the original line's slope... if the original slope is (-4/3) than the perpendicular slope is (3/4)... then you should just plug that new slope into point-slope form or slope-intercept form to get your equation... y-y1 = m(x-x1) ... y-1= (3/4)(x-1) ... so it would be y=(3/4)x + 1/4 then for part f just convert into standard form which is just manipulating the variables... look up standard form equation on Google and manipulate the variables from there.

Robert needs to cut four shelves from a board that is 2.5 meters long. The second shelf is 18 centimeters longer than twice the
aksik [14]
<span>there are 100 centimeters in a meter. 

therefore 2.5 meters = 2.5 * 100 = 250 centimeters. 

x = the length of the first board.
2x + 18 = the length of the second board.
x - 12 = the length of the third board.
x + 4 = the length of the fourth board. 

the total length of all the boards is equal to 5x + 10, 

since the total length of the board is 250 centimeters, then you get: 

5x + 10 = 250 

</span><span>solve for x to get x = 48 centimeters. 

the 4 board lengths are: 

x = 48
2x + 18 = 114
x - 12 = 36
x + 4 = 52 

add them up and you get a total of 250 centimeters. 

250 centimeters / 100 = 2.5 meters. 

this confirms the solution is good.

2. Simplify these expressions
skad [1K]

Answer:

Step-by-step explanation:

a 6ab + (-3x) + 2ab

we have  6ab + 2ab - 3x = 8ab - 3x

b. 12x + 4y + (-3x)

we have  12x - 3x + 4y = 9x + 4y

c 6w + (-2y) + 3w

we have  6w + 3w - 2y = 9w - 2y

d 4abc + (-9abc) + 10d

we have 4 abc - 9abc + 10d = - 5abc + 10d

Here for you.
