If f(x) = -2x + 8, and f(k) = -10, what is the value
of k? step by step please
Answer:
Value of k is 9
Step-by-step explanation:
-2x + 8 = -10
-2x = -10 - 8
-2x = -18
x = -18/-2
x = 9
f(x) = f(k)
x = k
9 = k
Hello there!
We are given the function:
[tex] \displaystyle \large{f(x) = - 2x + 8}[/tex]
We want to find the value of k. First, we know that f(k) is -10. We substitute x = k and f(x) = -10.
[tex] \displaystyle \large{f(k) = - 2k + 8} \\ \displaystyle \large{ - 10 = - 2k + 8}[/tex]
Solving the equation. First, we subtract both sides by 8.
[tex] \displaystyle \large{ - 10 - 8 = - 2k +8 - 8} \\ \displaystyle \large{ - 18 = - 2k} \\ [/tex]
Divide both sides by -2.
[tex] \displaystyle \large{ \frac{ - 18}{ - 2} = \frac{ - 2k}{ - 2} } \\ \displaystyle \large{ 9= k}[/tex]
Therefore, k = 9
When we substitute k = 9 in f(k), the value is -10.

If (x + 4)^2 = 49 and x <0, what is the value of x?
Answer:
x = - 11
Step-by-step explanation:
Take the square root of both sides.
sqrt(x+4)^2 = sqrt(49)
x + 4 = +/- 7
x + 4 = + 7
x = 3 Not what you want.
x + 4 = - 7
x = - 11
Determine if the two triangles shown are similar. If so, write the similarity statement.
Options:
A) The triangles are not similar.
B) ΔVML ∼ ΔUTM
C) ΔVML ∼ ΔUMT
D) Impossible to determine.
Based on the SAS similarity theorem, the right option is: C) ΔVML ∼ ΔUMT.
How to Determine if Two Triangles are Similar?In order to determine if two triangles are similar, find out if the ratio fo their corresponding side lengths are equal, that is, their lengths must be proportional to each other if they are similar triangles.
What is the SAS Similarity Theorem?The SAS states that if two pairs of sides of two triangles are proportional to each other, and they have a pair of corresponding congruent included angles, then they are similar triangles.
Given the image showing the two triangles, we have the following measures:
VM = 14, which is corresponding to UM = 49
LM = 8, which is corresponding to TM = 28
VM/UM = 14/49 = 2/7
LM/TM = 8/28 = 2/7
This means the two sides are proportional.
Also, angles VML and UMT are congruent to each other based on the vertical angles theorem.
Therefore, we can state that the ΔVML ∼ ΔUMT by SAS. The right option is C.

1/4s=15 solve for s. I’m not sure abt this

Variable s cannot be equal to 0 as division by zero is not defined. Multiply both sides of the equation by 4s.

Swap sides so that all variable terms are on the left-hand side.

What is simplification of an expression?
Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. It involves, multiply out the brackets and then simplify the resulting expression by collecting the like terms.
For the given situation,
The expression is {-10-3(10÷2)}-4
⇒ [tex][-10-3(\frac{10}{2} )]-4[/tex]
⇒ [tex][-10-3(5)]-4[/tex]

A 5000-seat theater has tickets for sale at $28 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue of $153,200?
Answer:
There are 3,900 tickets of $28 each and 1,100 tickets of $40 each sold.
Step-by-step explanation:
x = the number of $28 tickets
y = the number of $40 tickets
x + y = 5000
28x + 40y = 153200
x = 3,900 tickets
y = 1,100 tickets

Find m<1 if <1 is complementary to <2, <2 is supplementary to <3, and
m<3 = 126
Answer:
∠ 1 = 36°
Step-by-step explanation:
Supplementary angles sum to 180° then
∠ 2 + ∠ 3 = 180° , that is
∠ 2 + 126° = 180° ( subtract 126° from both sides )
∠ 2 = 54°
Complementary angles sum to 90° , then
∠ 1 + ∠ 2 = 90° , that is
∠ 1 + 54° = 90° ( subtract 54° from both sides )
∠ 1 = 36°

The optimal operating temperature of a given car engine is within 10°F of 190°F. Write an absolute value
inequality for the range of acceptable temperatures and solve the inequality.
The absolute value of inequality is 180 ≤ x ≤ 200 and its solution lies in [180, 200].
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
Suppose the operating temperature be x.
Then, as per the question the absolute difference of the temperature and 190°F is within 10°F.
It can be written in the form of inequality as follows,
|x - 190| ≤ 10
⇒ x - 190 ≤ 10 and x - 190 ≥ -10
⇒ -10 ≤ x - 190 ≤ 10
⇒ -10 + 190 ≤ x ≤ 10 + 190
⇒ 180 ≤ x ≤ 200
Thus, the range of acceptable temperatures lie in [180, 200].
Hence, the absolute value of inequality and its solution are given by 180 ≤ x ≤ 200 and [180, 200] respectively.
