Step 2: Solve for x
Distribute 2: 6x - 2 ≥ 4x - 6Subtract 4x on both sides: 2x - 2 ≥ -6Add 2 on both sides: 2x ≥ -4Divide 2 on both sides: x ≥ -2Here we see that any value x greater than or equal to -2 would work as a solution.
-2 (m+3) - 5m = -34
Help please
Answer:
m = 4
Step-by-step explanation:
Given
- 2(m + 3) - 5m = - 34 ← distribute and simplify left side
- 2m - 6 - 5m = - 34
- 7m - 6 = - 34 ( add 6 to both sides )
- 7m = - 28 ( divide both sides by - 7 )
m = 4

9514 1404 393
Answer:
D. 2/5
Step-by-step explanation:
The slope is the x-coefficient when the equation is solved for y.
2x -5y = 9 . . . . . . . given
-5y = -2x +9 . . . . . .subtract 2x
y = (-2/-5)x +9/(-5) . . . . divide by -5
y = 2/5x -9/5
The coefficient of x is 2/5. That is the slope of the line.
The slope is 2/5.
if x is 18 when y is 6 find y when x is 21
Answer:
y = 7, when x = 21
Step-by-step explanation:
Since 6 is 1/3 of 18 we could use that to find y
1/3 x 21 = 7

Helena has saved $595 to put toward snowboarding equipment and lift tickets at the hill. Each lift ticket costs $35. If she wants to have more than $420 of her savings left to spend on equipment, which inequality represents the number of lift tickets she can buy? A. X<5 B. X<4 (there is a line _ underneath the >) C. X>7 D. X>7 (there is a line _ underneath the >)
Answer:
[tex]x < 5[/tex]
Step-by-step explanation:
Given
[tex]Savings = \$595[/tex]
Rate of Lifting Ticket = $35 per ticket
Expected Amount = More than $420
Required
Determine the number of tickets she can buy
If the cost of lifting 1 ticket is 35, then the cost of x tickets is 35x.
Her spendings is then calculated as:
Total = Savings - Cost of lifting tickets
[tex]Total = 595 - 35x[/tex]
From the question, we understand that she wants to have more than 420 left.
This is represented as:
[tex]595 - 35x > 420[/tex]
Collect Like Terms
[tex]- 35x > 420 - 595[/tex]
[tex]- 35x > -175[/tex]
Divide through by -35
[tex]x < \frac{-175}{-35}[/tex]
[tex]x < 5[/tex]

The narrator of Fever 1793 makes it easy for readers to picture her upbringing by expressing her love for the nation, describing how it felt to see her words printed, confessing to counting on her fingers, and describing how it felt to voice her anger with front-of-the-house service.
On the road corners, shots were fired, and a cannon was fired in the public forecourt to clear the air. In addition to that, hornets, blowflies, and mosquitoes swarmed about us continuous.

Step-by-step explanation:
Given similar figures with ratio of sides = a : b , then
ratio of areas = a² : b²
ratio of sides = 15 ; 18 = 5 ; 6
The ratio of perimeters is equal to the ratio of sides, so
ratio of perimeters = 5 : 6
ratio of areas = 5² : 6² = 25 : 36

Some eighth-grade students want to raise at least $300 for a field trip by selling popcorn and fruit bars. The chart below shows the amount of profit they will make on each sale. If they sell exactly 500 fruit bars, how many boxes of popcorn will they need to sell to make a total of $300? 30 cents fruit bars. 60 cents box of popcorn
The total number of popcorn boxes is given by the equation
A = 250 boxes
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of boxes of popcorn be A
Now , the equation will be
Let the cost of one fruit bar = $ 0.30
Let the cost of one popcorn box = $ 0.60
The amount to be raised = $ 300
The number of fruit bars sold = 500
So , the cost of 500 fruit bars = 500 x cost of one fruit bar
Substituting the values in the equation , we get
The cost of 500 fruit bars = 500 x 0.30
The cost of 500 fruit bars = $ 150
Now , the remaining amount to be raised = 300 - 150
The remaining amount to be raised = $ 150
The number of boxes of popcorn A = remaining amount to be raised / cost of one popcorn box
Substituting the values in the equation , we get
The number of boxes of popcorn A = 150 / 0.60
The number of boxes of popcorn A = 250 boxes
Therefore , the value of A is 250 boxes
Hence , the number of boxes is 250

State the domain restriction(s) in interval notation of \displaystyle f\left(g\left(x\right)\right)f(g(x)) given: \displaystyle f\left(x\right)=\sqrt{3x-2}f(x)= 3x−2 and \displaystyle g\left(x\right)=x-7g(x)=x−7
Answer:
The interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].
Step-by-step explanation:
Consider the provided information.
It is given that [tex]\:f\left(x\right)=\sqrt{3x-2},\:\text{ and }\:g\left(x\right)=x-7[/tex]
We need to find the value of [tex]f\left(g\left(x\right)\right)[/tex].
Put the value of g(x) in [tex]f\left(g\left(x\right)\right)[/tex].
[tex]f\left(g\left(x\right)\right)=f(x-7)[/tex] ....(1)
Now, put x=x-7 in [tex]\:f\left(x\right)=\sqrt{3x-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3(x-7)-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3x-21-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3x-23}[/tex]
From equation 1.
[tex]f\left(g\left(x\right)\right)=\:f\left(x-7\right)= \sqrt{3x-23}[/tex]
The domain of the function is the set of input values for which a function is defined.
Here, the value of [tex]3x-23[/tex] should be greater or equal to 0 as the square root of a negative number is not real.
Domain= [tex]3x-23\geq0[/tex]
[tex]x\geq\frac{23}{3}[/tex]
The value of x is all real number greater than [tex]\frac{23}{3}[/tex].
Hence, the interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].

The calculated value of the gcf of 3x and 12x is 3x
Calculating the gcf of 3x and 12xFrom the question, we have the following parameters that can be used in our computation:
Expressions = 3x and 12x
Expand both expressions
So, we have
3x = 3 * x
12x = 2 * 2 * 3 * x
Multiply the common factors
GCF = 3 * x
Evaluate
GCF = 3x
Hence, the gcf of 3x and 12x is 3x

show that each quadrilateral with the given vertices is a parallelogram.
J(-2,-2), K(-3,3), L(1,5), M(2,0)
9514 1404 393
Answer:
J +L = K +M = (-1, 3)
Step-by-step explanation:
The figure JKLM is a parallelogram if the midpoints of the diagonals are the same point. That is, ...
(J +L)/2 = (K +M)/2
Multiplying by 2 makes this a simpler test:
J +L = K +M
In this quadrilateral, those sums are ...
J +L = (-2, -2) +(1, 5) = (-2+1, -2+5) = (-1, 3)
K +M = (-3, 3) +(2, 0) = (-3+2, 3+0) = (-1, 3)
The midpoints are the same, so the quadrilateral is a parallelogram.

1.) Find the LCF of 8 and 4:[tex]8,4=8[/tex]- We do this because in order to add the fractions together, they have to have the same denominator. In this case you find the LCF, (Least Common Factor) of 8 and that turns into the denominator for both.
2.) Convert the fractions to have the same denominator: [tex]\frac{5}{8}=\frac{5}{8}[/tex][tex]\frac{3}{4}=\frac{6}{8}[/tex]- [tex]\frac{5}{8}[/tex] stays the same, but [tex]\frac{3}{4}[/tex] changes to [tex]\frac{6}{8}[/tex] because the LCF if 8, and to get to 8 we had to multiply 4 by 2. So since we multiplied the denominator, you must do the same to the numerator, hence why we went from 3 to 6.
3.) Add the numerators: [tex]5+6=11[/tex]- Since [tex]\frac{5}{8}[/tex] and [tex]\frac{6}{8}[/tex] have the same denominator, all you have to do is add the numerator.
