Answer:
[tex]\angle A=17\textdegree[/tex]
Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:
[tex]\angle A+\angle B=90[/tex]
Since we know their equations, substitute:
[tex](x+8)+(8x+1)=90[/tex]
Solve for x. Combine like terms on the left:
[tex]9x+9=90[/tex]
Subtract 9 from both sides:
[tex]9x=81[/tex]
Divide both sides by 9:
[tex]x=9[/tex]
So, the value of x is 9.
We want to find A. So, let's use the equation for A:
[tex]\angle A=x+8[/tex]
Substitute 9 for x:
[tex]\angle A=9+8[/tex]
Add:
[tex]\angle A=17\textdegree[/tex]
So, the measure of A is 17°.

Joe had a summer job that pays $7.00 an hour and he worked 15 and 35 hours every week. His weekly salary can be modeled by the equation: s = 7H, wear a is his weekly salary and h is the number of hours he worked in a week. Describe the domain and range for this problem using appropriate notation.
Correct question is;
Joe had a summer job that pays $7.00 an hour and he worked between 15 and 35 hours every week. His weekly salary can be modeled by the equation: S = 7h, where S is his weekly salary and h is the number of hours he worked in a week.
What is the reasonable Domain and Range?
Answer:
Domain is: 15 ≤ x ≤ 35
Range is: 105 ≤ x ≤ 245
Step-by-step explanation:
We are told that Joe works between 15 and 35 hours every week.
This means that he works at least 15 hours or at most 35 hours a week.
Thus, domain is; 15 ≤ x ≤ 35
We are told that his weekly salary can be modeled by the equation: s = 7H
Where s is salary and H is number of hours worked per day.
Thus;
Lower range is; s = 7 × 15 = $105
While higher range is; s = 7 × 35 = $245
Thus, range is 105 ≤ x ≤ 245

Help Simplify 6(x + 4).
Answer:
6x+24
Step-by-step explanation:
The simplified form of the expression 6(x + 4) is 6x + 24.
We have,
To simplify the expression 6(x + 4), we can apply the distributive property of multiplication over addition.
The distributive property states that when we have a number multiplied by a sum of terms, we can distribute the multiplication to each term separately and then simplify.
In this case, we have 6 multiplied by the sum (x + 4). Applying the distributive property, we can multiply 6 by both x and 4:
6(x + 4) = 6 * x + 6 * 4
Simplifying further:
6x + 24
Therefore,
The simplified form of the expression 6(x + 4) is 6x + 24.

Write the sentence as an inequality.
The sum of a number y and 9 is at least -1.
y +9 >= -1
Sum of a number(y) and 9. Is greater than or equal to negative one. Sum means add, so add y, and 9. It has to be atleast negative one, so greater than (0,1,2,3...), or equal to(-1).
Hope this helps, if you have more questions, feel free to ask.
The sum of a number y and 9 is at least -1 as an inequality is y + 9 ≥ 1.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
An expression,
The sum of a number y and 9 is at least -1.

Janet bought same bars of choclate to share equally with her friends. she bought between 35 and 50 bars altogether. if she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over. If she shares the bars equally with 6 friends she will have 5 bars left over. How many bars of chocolate did she buy?
a.47
b.45
c.46
d.48
For the conditions to be fulfilled number of chocolate bars Janet bought is 35.
What is an equation?An equation is a statement in form of numbers and variables that both sides are equal.
Janet bought the same bars of chocolate to share equally with her friends and it is between 36 and 50.
There are two possible cases,
Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'A'.
(i) If she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over,
∴ N = 7A + 7...(i).
(ii) If she shares the bars equally with 6 friends she will have 5 bars left over,
Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'B'.
∴ N = 6B + 5...(ii)
Now, we have to equate these two equations,
7A + 7 = 6B + 5.
7A = 6B - 2.
A = (6B - 2)/7.
From here we have to find such integer value of B which also makes the value of A an integer and also when we put the values of either A or B in our equations it should lie between 35 and 50.
So,
A = (6B - 2)/7.
When B = 5 then A = 4. Or when B = 12 the A = 10.
But the B = 12 and A = 10 is inadmissible.
Now, we'll put the value of A or B in eqn (i) or (ii).
Which results in N = 35.
So, the number of chocolate bars she bought is 35.

Plug in x = -5. Use PEMDAS to simplify
f(x) = |3x-2|
f(-5) = |3(-5)-2| ... replace every x with -5
f(-5) = |-15-2|
f(-5) = |-17|
f(-5) = 17

Repeat for x = 7
f(x) = |3x-2|
