Answer:
A and D are correct!
Step-by-step explanation:
The origin is 0,0
The x axis is the one that R is on right now
The correct statements are,
A) The point is 3 units right to the origin.
D) The x coordinate is 3.
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
The point R is shown in graph.
Nom,
Since, The point R is shown in graph.
Clearly, The coordinate of R = (3, 0)
So, We have;
⇒ The point R is 3 units right to the origin.

Answer: B, C, D
Step-by-step explanation:
6x + 1 - (3x -1)
=> 6x + 1 - 3x + 1
=> 3x + 2
So Answers: B, C, D
The expression that should be equivalent to 6x + 1 - (3x - 1) is option B, C, D.
Calculation of the expression:Since the equation is 6x + 1 - (3x - 1)
So,
6x + 1 - (3x -1)
6x + 1 - 3x - (-1)
6x + 1 -3x + 1
And, 3x + 2
Therefore, we can conclude that The expression that should be equivalent to 6x + 1 - (3x - 1) is option B, C, D.

You work at a frozen yogurt shop during the summer. You need to order 5-ounce and 8-ounce cups. The storage room will only hold 10 more boves. A box of 5 ounce cups cost $100 and a box of 8-ounce cups costs $150. A maximum of 1200 is budgeted for yogurt cups. Write a system of linear inequalities that shows the number of bonus of 5 ounce and 8 ounce cups that could be bought. Graph your result
Answer: 5 Boxes
The way i did it: f+e =10
Value equation...:100f+150e=1250
Modify:100f+100e=1000
Substract the 1st from the 2nd to solve for e
50e=250
e=5 boxes
f+e=10 so f equals 5 boxes

Write the equation of a line that goes through (4,3) and has a slope of m=2
Answer:
y = 2x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, then
y = 2x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = 8 + c ⇒ c = 3 - 8 = - 5
y = 2x - 5 ← equation of line

The value of Rita's house increased by 5%.
Her house then had a value of £210 000.
Work out the value of Rita's house before the increase.
Answer: £200,000
Step-by-step explanation:
From the question, we are informed that the value of Rita's house increased by 5% and that her house then had a value of £210 000.
The value of Rita's house before the increase will be calculated as:
= 210,000 ÷ (100% + 5%
= 210000 ÷ 105%
= 210000 ÷ 105/100
= 210000 × 100/105
= £200,000

2. Tadashi and his friend Abel make 18 dumplings. Tadashi eats one third, and Abel eats the rest. How many dumplings did Abel eat?
Answer:
12
Step-by-step explanation:
18/3=6
so Tadashi ate 6 dumpling; the other 12 Able ate
Answer:
12
Step-by-step explanation:
Sine Tadashi eats one third, you have to divide the total amount of dumplings by three.
18/3=6
Tadashi eats 6 dumplings, so to find out how many Abel eats you have to subtract 6 from the total number of dumplings.
18-6=12
Abel ate 12 dumplings

Can you solve the equation?
Answer:
x=3 and 9
Step-by-step explanation:
; x-3=0
x=3 (change side change mark)
and
[tex] \frac{2}{3} x - 6 = 0[/tex]
[tex] \frac{2}{3} x = 6[/tex]
[tex]x = 6 \times \frac{3}{2} [/tex]
change side change mark.
So, x=9
If u wanna check the answer you can check by substitution x=3 and 9 in equation.
