-2.5(-2-3x)+2.5(-4x-1)=-2x-4x
Answer:
x=−0.714286
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2.5(−2−3x)+2.5(−4x−1)=−2x−4x
(−2.5)(−2)+(−2.5)(−3x)+(2.5)(−4x)+(2.5)(−1)=−2x+−4x(Distribute)
(7.5x+−10x)+(5+−2.5)=(−2x+−4x)(Combine Like Terms)
Step 2: Add 6x to both sides.
Step 3: Subtract 2.5 from both sides.
Step 4: Divide both sides by 3.5.
x=−0.714286
can someone please help me and explain how to change 2x − 3y = 9
into slope intercept form
Answer:
y=2/3x-3
Step-by-step explanation:
first, you have to isolate the y, so subtract 2x from both sides. -3y=-2x+9
Next, we must divide all sides by -3, so y=-2/-3x-3
Finally, simplify the equation to y=2/3x-3
Answer:
y=mx+b
y=2/3x + -3
2/3 is the slope points are (0,-3)
Step-by-step explanation:
2x-3y =9
subtract 2x from each side leaving it -3y = -2x +9
now divide both sides by -3 -3y/-3=-2x/-3 +9/-3
y= 2/3+ -3

A student did an experiment to test the hypothesis that brand name paper towels soak up water better than generic paper towels. What would be the independent variable in the student's experiment?
Answer: The independent variable is the brand and the dependant variable is the amount of water you use.
Step-by-step explanation:
The Independent variable is the condition that you change in an experiment.
The dependant variable is the condition that you measure in an experiment.
The independent variable in the student's experiment is the type of paper towel used.
In an experiment, there are three types of variables:
The independent variable : the experimenter can change or manipulate this variable in order to determine its effect on the dependent variable. The dependent variable : this is the variable whose value would be determined in the experiment.The extraneous variable : this is the variable that can affect the result of the experiment but it is not researched in the experiment.In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.

Michelle is making a poster for a class presentation. She plans to have four sections of information, each with a different background color. The diagram shows the lengths and widths of each section, where a is the length of the red section. Which expression for the area of the poster is written as the sum of the areas of each colored section? (answer choices are in the screenshot provided. thanks! <3)
Answer:
first option
Step-by-step explanation:
the area of a rectangle is
base*height
[tex]Purple=(3)\times(a)\\\\=3a\\\\\\Green=(\frac{1}{2})\times(3)\\\\=\frac{3}{2}\\\\\\Red=1\times a\\\\=a\\\\\\Yellow=\frac{1}{2}\times 1\\\\=\frac{1}{2}[/tex]
so the sum is
[tex]\Sigma A=3a+a+\frac{3}{2}+\frac{1}{2}[/tex]
which is the first option
The expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2
Area of a rectangle = length × width
Purple color:
Area = length × width
= 3 × a
= 3a
Red color:
Area = length × width
= 1 × a
= a
Green color:
Area = length × width
= 3 × 1/2
= 3 1/2
Yellow color:
Area = length × width
= 1 × 1/2
= 1/2
Sum of the areas = purple + red + green + yellow
= 3a + a + 3 1/2 + 1/2
Therefore, expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2

Sue Ling gave her dad a $50 gift certificate. He plans to buy a $12 book on home repair
and as many drill bits as he can for $1.79 each. Choose the inequality that shows x, the
number of drill bits he can buy.
I
Answer:
12 + 1.79(x) ≤ 50
Number of drill bits = 21
Step-by-step explanation:
Given:
Total amount = $50
Amount of book = $12
Price of each bit = $1.79
Find:
Number of drill bits
Computation:
Assume, Number of drill bits = x
So,
12 + 1.79(x) ≤ 50
1.79(x) ≤ 38
x ≤ 21.220
Number of drill bits = 21
Triangle EFG has vertices E(–3, 4), F(–5, –1), and G(1, 1). The triangle is translated so that the coordinates of the image are E’(–1, 0), F’(–3, –5), and G’(3, –3).
Which rule was used to translate the image?
T4, –4(x, y)
T–4, –4(x, y)
T2, –4(x, y)
T–2, –4(x, y)
Answer:
C.) T2, -4(x, y)Step-by-step explanation:
did on edge :)
The rule of translation of the triangle EFG is (c) T-2,4(x,y)
How to determine the translation rule?We have:
Pre-image: E(–3, 4), F(–5, –1), and G(1, 1).Image: E’(–1, 0), F’(–3, –5), and G’(3, –3).Taking E and E', we have:
E = (-3, 4)
E' = (-1, 0)
Subtract E from E'.
So, we have:
(x, y) = (-1 + 3, 0 - 4)
Evaluate
(x, y) = (2, -4)
This can be rewritten as:
T-2,4(x,y)
Hence, the rule of translation is (c) T-2,4(x,y)

for the equation x + y = 3. How many possible values for x are there if x and y are both whole numbers?
A.2
B.3
C.4
Answer:
A
Step-by-step explanation:
Because it is 2+1 and 3+0, those are the only solution, therefore A is correct
======================================================
Explanation:
The set of whole numbers is {0, 1, 2, 3, ...}
So we include 0 and any positive number that doesn't have decimal or fractional components to it. Negative values are not included.
If we plug in x = 0, then x+y = 3 solves to y = 3If we plug in x = 1, then x+y = 3 solves to y = 2If we try x = 2, then x+y = 3 solves to y = 1Lastly, x = 3 leads to y = 0Whatever you pick for x, the y value must add to it to get 3. Both x and y must be numbers from the set of whole numbers.
There are four cases shown in the bullet points above, so we have four different solutions. We can't move onto x = 4 because the y solution would be y = -1, but -1 is not in the set of whole numbers.
What is the value of the expression (x – 2y)(x + 2y) when x= 4 and y = 2?
Answer:
0
Step-by-step explanation:
To solve this, you first plug in the 4 and 2 where the x and y's go, making the expression (4 - 2(2))*(4 + 2(2)). Then you solve each parenthesis (below).
(4 - 2(2))*(4 + 2(2)).
(4 - 4)*(4 + 4).

Write an equation of the line that passes through (3,7) and is parallel to the line shown.
An equation of the parallel line is y=__.
at first we should find the equation of this line so we should find a in the equation of y = a x + b and we do not care about b as it is parallel so a = ( (4 -(-2)) ÷ 1 -(-2)) = 2 so y = 2 x + b and we put x = 3 and y = 7 the result is 7 = 2×3 + b and b = 7 - 6 = 1 the equation is y = 2x + 1

if f(x)=3^x+10 and g(x)=2x-4, find (f-g)(x)
=====================================
Work Shown:
(f - g)(x) = f(x) - g(x)
(f - g)(x) = ( f(x) ) - ( g(x) )
(f - g)(x) = ( 3^x + 10 ) - ( 2x-4 )
(f - g)(x) = 3^x + 10 - 2x+4
(f - g)(x) = 3^x - 2x + (10+4)
(f - g)(x) = 3^x - 2x + 14

Jessica walks 1/3 miles to the post office and then 2/5 mile to the library. How far did Jessica walk altogether?
Answer:
11/15
Step-by-step explanation:
Ainsley walks 3/5 mile in 1/3 of a day. Sarah walks 5/8 mile in 2/6 of a day. Who walked farther, Ainsley or Sarah? Find the unit rate for each girl and then tell who you think walked farther with the correct unit rate given below. *
[tex]Ainsley \: walked \: in \: \frac{1}{3} \: \: of \: a \: day \ \: = \frac{3}{5} mile[/tex]
[tex] = \frac{1}{3} \times 24 = \frac{3}{5} [/tex]
[tex]8 \: hours = \frac{3}{5} \: miles[/tex]
[tex]Sarah \: walked \: in \: \frac{2}{6} of \: a \: day \: = \frac{5}{8} miles[/tex]
[tex] \frac{2}{6} \times 24 = \frac{5}{8} [/tex]
[tex]8 \: hours \: = \frac{5}{8} \: miles[/tex]
Let us see who walked more :
[tex]Ainsley \: walked \: = \frac{3 \times 8}{40} [/tex]
[tex] = \frac{24}{40} \: miles[/tex]
[tex]Sarah \: walked \: = \frac{5 \times 5}{40} [/tex]
[tex] = \frac{25}{40} \: miles[/tex]
[tex] \frac{24}{40} < \frac{25}{40} [/tex]
Sarah walked farther than Ainsley .
[tex] \frac{25}{40} - \frac{24}{40} = \frac{1}{40} \: miles[/tex]
∴ Sarah walked farther than Ainsley by 1/40 miles .

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Jesse wants to purchase three binders and a backpack. If the backpack costs $16
From the data given in the question:
The linear equation can be framed as follows:
y = 16 + 3x
Or
16 + 3x = y
Thus, the equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.
The options are:
16+y=3x
16+3x=y
y+3x=16
