Answer:

B) The y-coordinate is 0

Step-by-step explanation:

We are given that,

'In an x-y plane, the x-axis consists of all the ordered pairs of the form (x,y)'.

It is required to find the condition on the ordered pairs.

Since, we know that,

On the x-axis, the value of y= 0.

So, 'x-axis contains the ordered pairs of the form (x,0)'.

Thus, option B is correct.

Answer:

Option B

y coordinate is 0

Step-by-step explanation:

We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.

X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0

To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.

Thus we have along x axis, y values to be 0

Hence any point on x coordinate will be of the form (a,0) where a can be any real number

So option B is right

Zepler [3.9K]
H(x)=5x+15+4x+20

if x=4, together it would be 5(4)+15+4(4)+20
h(x)=20+15+16+20=71
Divided by 2, they'd each get 35.5

If Frank worked alone, he'd get 5(4)+15= 35
He'd make more working together.

Li rode her bike 25% of the way to school. She rode 5 blocks. How many blocks does Li live from school?
Alenkasestr [34]

Answer:

20 Blocks

Step-by-step explanation:

First you would realize that 5 blocks is only 1/4 of the way to school because 1/4 is 25%

Next you should know that you just need to add 5 four times.

Lastly you would multiply 4*5=20

So therefore she lives 20 blocks from her school

Alicia wants to bake a cake with ⁹/10 grams of flour.However,she only has ⅓ grams of flour she needs.How much does she have?
natali 33 [55]

Answer:

We know that:

She needs 9/10 grams of flour for the cake (this quantity does not make a lot of sense, maybe is written incorrectly, but is the only info we have, so let's solve the problem with this)

She only has 1/3 of the amount she needs.

How much flour does she have?

Well, she needs 9/10 grams, and she has one-third of that.

Then she has (1/3) times (9/10) grams, this is:

F = (1/3)*(9/10) grams

F = (1*9)/(3*10) grams

F = 9/30 grams

That is the amount of flour that she has.
