Answer:
x=−1/2 y+ 1/2
Step-by-step explanation:
Let's solve for x.
6x+3y=3
Step 1: Add -3y to both sides.
6x+3y+−3y=3+−3y
6x=−3y+3
Step 2: Divide both sides by 6.
6x /6= −3y+3/6
x=−1/2 y+ 1/2

My cookbook says that a salad sauce should be made of 1/3 lemon juice and
2/3 oil. I put 30 ml of oil but my hand slipped when adding the lemon juice
and the total volume is now 70.
How much oil must I now add to have the correct proportions?
Answer:
50ml
Step-by-step explanation:
as u put 30ml oil and u have 70 so 70-30 is 40 which is 40ml lemon juice. as 1 part is lemon and 2 parts oil out 2x40 so 80ml but as u already have 30 in there only put 50 :)
4. The length of a rectangle is eight more than
twice its width. The perimeter is 96 feet. Find
the dimensions of the rectangle.
Answer:
length = 104/3 ft
width = 40/3 ft
Step-by-step explanation:
Variables:
L = length
w = width
Set up equations:
L = 8 + 2w2L + 2w = 96Substitute L with the first bullet point equation:
2L + 2w = 96
2(8 + 2w) + 2w = 96
16 + 4w + 2w = 96
16 + 6w = 96
6w = 80
w = 40/3 ft
Find L now that you have the value of the width:
L = 8 + 2w
L = 8 + 2(40/3)
L = 8 + 80/3
L = 104/3 ft
Final Values:
length = 104/3 ft
width = 40/3 ft
What are the coordinates of R' after a dilation by a scale factor of 3, centered at the origin, followed by the translation (x, y) - (x, y + 3)?
A. (9, 8)
B. (12, 18)
C. (9, 18)
D. (9, 24)
9514 1404 393
Answer:
C. (9, 18)
Step-by-step explanation:
Given R(3, 5), a dilation by a factor of 3 will multiply each coordinate to give ...
(9, 15)
Then the translation up by 3 will give you the image coordinates ...
(x, y) ⇒ (x, y+3)
(9, 15) ⇒ (9, 15 +3) = (9, 18)
The coordinates of R' are (9, 18), matching choice C.
_____
Comment on multiple choice answers
As it often does, here it works to "guess" the answer that has the coordinates that are most-repeated. An x-coordinate of 9 is part of 3 answer choices; a y-coordinate of 18 is the only repeated value in the answer choices. If you were to guess, an appropriate guess would be (9, 18). That happens to be correct in this case.
Answer: C. (9,18)
Step-by-step explanation: I have had this question on a quiz before.

2. Are these triangles congruent?
a) no, this is the SSA one
b) yes, by ASA
C) Yes, by SAS
D) Yes, by AAS
Answer:
D
Step-by-step explanation:
2x -y =3; D:{-2,0,1,3}
Answer: y= 2x-3
Step-by-step explanation:
2x-y =3
-2x -2x
-y= 3-2x
-y=-2x+3/-1
y=2x-3
Is this a linear equation
4xy + 2y = 9
Answer:
no
Step-by-step explanation:
because you have two variables x and y, and there is two letters attached to one number 4xy, so no is not a linear equation

Find the slope and y-intercept.
Answer:
y-intercept = -5, slope = 5/3
Step-by-step explanation:
The y-intercept is where on the y-axis (vertical line) does the graph cross. The slope can be found many different ways. My method for this graph was simply counting up the graph until I got to the point where the graph crosses another whole number on the x-axis and then counted over. This makes sense because slope is rise over run so if you go up 5 (from the y-intercept) and then over 3 (to get to the next whole number point) then your slope is 5/3
8.) Find the value of x.

HELP ME PLEASE
In a triangle,
3 angles are:
80
100 + x
40
By angle sum property of triangle,
80 + 100 + x + 40 = 180
220 + x = 180
x = 180 - 220
x = -40
6x−5y=15
x=y+3
What X = and what does Y= in this problems?
Answer:
y = − 3 in this problem.
Answer:
X= (5y+15)/6 Y= x-3
Step-by-step explanation:
6x - 5y = 15
+5y +5y
--------------------
6x= 5y + 16
/6 /6 /6
= (5y+16)/6
~~~~~~~~~~~~~~~~~
x= y + 3

Slope of -3 and goes through the point (6, -10) slope intercept form need this ASAP
What is the slope of the line, what does the slope represent? write an equation for emma’s graph x=time and y=distance
Answer:
5/2 or 2.5
Step-by-step explanation:
Slope formula:
(y₂ - y₁) / (x₂ - x₁)
Two points are given:
(2, 5) and (6, 15)
x₁ = 2
y₁ = 5
x₂ = 6
y₂ = 15
Substitute and solve:
(15 - 5) / (6 - 2)
10 / 4
5/2 or 2.5
