Given h(x) = 2x + 4, solve for x when h(x) = -8
Answer:
x = -6
Step-by-step explanation:
-8 = 2x + 4
subtract 4 giving you -12 = 2x
divide 2 giving you -6 and leaving x by itself
therefore the answer is x = -6

I have a pile of socks which contains 12 white socks, 12 black socks, and 12 red socks. How many socks must I take from the pile to be certain that I have at least one matching pair?
Answer:
I would say 6 but i do not know
Step-by-step explanation:
bc 6x2=12
The least number of socks to be taken from the pile to have one pair of socks is given by the equation A = 4
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 socks to be taken be represented as A
Now , the equation will be
The number of white socks = 12
The number of black socks = 12
The number of red socks = 12
So , let the first sock be taken be either a white , black or red
Now , the second sock can also be either a white , black or red
And , the third sock can also be either a white , black or red
But , the fourth sock must a white or black or red and it will form a pair of similar colored sock
Therefore , the number of times is 4
Hence , the number is 4

what is an equivalent expressions to 12r+t-4r+6t
Answer:
8r+7t
Step-by-step explanation:
Answer:
An equivalent expression to 12r + t - 4r + 6t is 8r + 7t
Step-by-step explanation:
You just need to combine like-terms together, 12r and -4r, t and 6t, to get to 8r + 7t.
Solve the system of linear equations below: y= 4x-9 y= x-3
[tex] \begin{cases} y = 4x - 9 \\ y = x - 3 \end{cases}[/tex]
We can combine both equations
[tex]4x - 9 = x - 3[/tex]
Solve the equation.
[tex]4x - x = 9 - 3 \\ 3x = 6 \\ x = \frac{6}{3} \longrightarrow \frac{2}{1} \\ x = 2[/tex]
Then we substitute the value of x in any given equations which I will be substituting in the second equation
[tex]y = x - 3 \\ y = 2 - 3 \\ y = - 1[/tex]
Therefore, from x = 2 and y = -1, the solution is (2,-1)
Answer Check
Substitute the value of x and y in both equations.
First Equatio
[tex]y = 4x - 9 \\ - 1 = 4(2) - 9 \\ - 1 = 8 - 9 \\ - 1 = - 1[/tex]
Second Equation
[tex]y = x - 3 \\ - 1 = 2 - 3 \\ - 1 = - 1[/tex]
Both equations are true for (2,-1).
Answer[tex] \begin{cases} x = 2 \\ y = - 1 \end{cases} \\ \sf \underline{coordinate} \\ (2,-1)[/tex]
Answer:
(2, - 1 )
Step-by-step explanation:
Given the 2 equations
y = 4x - 9 → (1)
y = x - 3 → (2)
Substitute y = 4x - 9 into (2)
4x - 9 = x - 3 ( subtract x from both sides )
3x - 9 = - 3 ( add 9 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = 2 - 3 = - 1
solution is (2, - 1 )

At a construction job for a mansion there are 32 painters. Of these painters, 24 of them are painting the interior of the mansion. What percent of these painters are painting the interior?
Answer:
[tex]\% Percent = 75 \%[/tex]
Step-by-step explanation:
Given
[tex]Painters = 32[/tex]
[tex]Interior\ Painters = 24[/tex]
Required
Determine the percentage of the interior painters
This percentage is calculated as:
[tex]\% Percent = \frac{Interior\ Painters}{Painters} * 100\%[/tex]
This gives:
[tex]\% Percent = \frac{24}{32} * 100\%[/tex]
[tex]\% Percent = \frac{24* 100\%}{32}[/tex]
[tex]\% Percent = \frac{2400\%}{32}[/tex]
[tex]\% Percent = 75 \%[/tex]
75% are painting the interiors

Anu borrowed Rs 4000 from a bank at 7 % per annum for 2 years. She then lent this amount to Nidhi at 9 % per annum for the same period. How much did Anu gain in this transaction?
Step-by-step explanation:
p- 4000
r- 7
t-2years
SI- P×r×t/100
SI-4000×7×2/100
SI- 4000×14/100
SI- 56000/100
SI- 560
so anu give = p+ SI
= 4000+560
= 4560 ₹
p- 4000
r- 9
t-2 years
SI- P×r×t/100
SI- 4000×9×2/100
SI- 4000×18/100
SI- 72000/100
SI- 720
so nidhi give= p+SI
= 4000+720
= 4720
