Anyone down to help? 12pts for PRE-ALGEBRA question Use the information in the table for 2–4.
Answer:
See attached image
Step-by-step explanation:
If the number of blueberries is the x value, and number of calories is the y value, then we can create the ordered pairs (5,4) (10,8) (15,12) based on the data in the table.
Plotting these on the graph is simple - just go to the x value then the y value and plot where these lines meet.
The slope of a line is always the rise over run.
Every time our x increases by 5, our y increases by 4. The rise is 4, and run is 5, so the slope is [tex]\frac{4}{5}[/tex]

Celina and Zoe both sing in a band.
One evening the band plays for 80 minutes.
Celina sings for 65% of the 80 minutes.
8
Zoe sings for of 5/8 of the 80 minutes.
Celina sings for more minutes than Zoe sings.
Work out for how many more minutes.
Step-by-step explanation:
65% of 80= 80×0.65 = 52mins
5/8 of 80= 5/8×80 = 50 mins
more mins = 52-50= 2 more minWhat is the degree for this

Solve 2x + 3y = 11 and 2x - 4y = -24 and hence find the value of 'm' for which y=mx+3.
Answer:
m=-1
Step-by-step explanation:
2x+3y=11............. (eqn 1)
2x-4y=-24...........(eqn 2)
Subtract eqn 1 from eqn 2
7y=35
y=5
Substitute for y in eqn 1
2x+3(5)=11
2x+15=11
2x=11-15
2x=-4
x=-2
y=mx+3
5=-2m+3
5-3=-2m
2=-2m
m=-1
Answer:Here,
2x+3y=11..........(i)2x-4y= -24......... (ii)Subtracting (ii) from (i),we get
2x+3y=11
- 2x+4y=24
___________
7y =35
y=5
Substituting y = 5 in (i) we get
2x+3×5=11
or,2x +15 =11
or,2x = 11- 15
or,x= -2
Now,
We know,y=mx+c
5=m ×(-2) +3
or,2=m×(-2)
or,2/-2 =m
m= -1
find the equation of the line parallel to H passes through (-4,2)
Answer:
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{10}{3}[/tex]
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 )
Calculate the slope m of H using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line
m = [tex]\frac{-2+3}{3-0}[/tex] = [tex]\frac{1}{3}[/tex]
Parallel lines have equal slopes, thus
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 4, 2) into the partial equation
2 = - [tex]\frac{4}{3}[/tex] + c ⇒ c = 2 + [tex]\frac{4}{3}[/tex] = [tex]\frac{10}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{10}{3}[/tex] ← equation of parallel line

Given that a rectangle with length $3x$ inches and width $x + 5$ inches has the property that its area and perimeter have equal values, what is $x$
Answer:
First, we need to know how to calculate the area and the permiter of a rectangle.
To calculate the area, we multiply base by height and to calculate the perimeter, we sum all sides.
Knowing this, we can say that the area is 3x * (x+5) and the perimiter is 3x + 3x + x + 5 + x + 5, as we know both are the same, we write it as an equation:
[tex]3x * (x+5) = 3x + 3x + x + 5 + x + 5[/tex]
Now we solve the equation:
[tex]3x^2 +15x = 6x + 2x + 10[/tex]
[tex]3x^2+15x =8x + 10[/tex]
[tex]3x^2+15x-8x-10=0[/tex]
[tex]3x^2+7x-10=0\\\\x_1=\frac{-10}{3}\\x_2 = 1[/tex]
As the negative result doesn't have sense, we only pick the second one: 1.
If x = 1, then area would be 3*6 = 18 square inches and perimeter 3+3+6+6 = 18 inches
Answer:
[tex]\huge\boxed{x = 1 \ \ \ \ OR \ \ \ \ x = -\frac{10}{3} }[/tex]
Step-by-step explanation:
Length = 3x
Width = x + 5
Area of Rectangle:
=> (Length)(Width)
=> (3x)(x+5)
=> [tex]3x^2 + 15x[/tex]
Perimeter of Rectangle:
=> 2 (Length) + 2 (Width)
=> 2(3x) + 2(x+5)
=> 6x + 2x + 10
=> 8x + 10
Given Condition is:
Perimeter = Area
[tex]3x^2 + 15x[/tex] = 8x + 10
[tex]3x^2 + 15 x -8x - 10 = 0\\3x^2 + 7x -10 = 0\\3x^2 + 10 x - 3x -10 = 0\\x(3x+10) - 1(3x+10) = 0\\(x-1) (3x+10) = 0[/tex]
Either,
x - 1 = 0 OR 3x + 10 = 0
x = 1 OR 3x = -10
x = 1 OR x = -10 / 3

–2 times the quantity q minus 3
Answer:
This question was worded weirdly however I am assuming this is algebra and you need the equation. So here- -2(q-3) or -2q+6
Step-by-step explanation:
Distribute the -2, to all the terms in the parenthesis of -2(q-3) you get 2q+6
If you didnt know how to get -2(q-3), -2(multiplied) by q-3, you use parenthesis to make sure you know it is multiplication in front of the parenthesis.
Hope I could help!

6c-8-2c=-16+c what’s the value of c
Answer:
The correct answer is c = -8/3.
Step-by-step explanation:
The first step in solving this problem would be to simplify by combining like terms on the left side of the equation.
6c - 8 - 2c = -16 + c
4c - 8 = -16 + c
Then, we can subtract c from both sides of the equation to get rid of the positive c on the right side of the equation.
4c - c - 8 = -16 + c - c
3c - 8 = -16
Next, we can add 8 to both sides of the equation.
3c - 8 + 8 = -16 + 8
3c = - 8
Then, we can divide both sides of the equation by 3.
c = -8/3

if EF bisects CD, CG =5x-1, GD = 7x-13, EF = 6x-4, and GF =13, find EG
Greetings from Brasil....
As stated in the statement of the question, EF is a bisector of CD, so point G is the median point of CD, so CG = GD
5X - 1 = 7X - 13
X = 6
EF = EG + GF
6X - 4 = EG + 13 x = 6, so
6·6 - 4 = EG + 13
EG = 19(see attachment)
A line segment is also a line but the line with finite length and having fixed endpoints. The length of the line segment EG is 19 unit.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
Given that EF bisects CD at point G, therefore, the line segment CD will be divided into two equal parts, CG and GD. Therefore, we can write,
CG = GD
5x - 1 = 7x - 13
-1 + 13 = 7x - 5x
12 = 2x
x = 12/2
x = 6
Further, the length of segment EG will be,
EG = EF - GF
= 6x - 4 - (13)
= 6x - 4 - 13
= 6x - 17
= 6(6) - 17
= 36 - 17
= 19
Hence, the length of the line segment EG is 19 unit.

A simple way to tell if a relation is a function is by taking a look at the X value, which is on the left. If the X value repeats again (ex: (0,1) (0,2) or (5,3 (5,7)) it is not a function. However, the Y value is allowed to repeat.

After taxes, Alexandra's take home pay is 3 10 of her salary before taxes. Enter and solve an equation to find Alexandra's salary before taxes for the pay period that resulted in $162 of take-home pay. Let s represent your variable. The equation is . Alexandra's salary before taxes for the pay period was $
Answer:
The equation is 3/10 × s = 162
Alexandra's salary before taxes for the pay period was $540
Step-by-step explanation:
Let
Alexander's salary before taxes
=s
3/10 if Alexander's take home pay is $162 after taxes
3/10 of s = $162
The equation is
3/10 × s = 162
Divide both sides by 3/10
s = 162 ÷ 3/10
= 162 × 10/3
= 1620 / 3
= $540
Alexandra's salary before taxes for the pay period was $540
