Answer:
58°
Step-by-step explanation:
in ΔABD
∠ADB = 32°
∠DBA = 90°
∠BAD = 180° - (32 + 90)
∠BAD = 58°
As ΔBAD ≅ ΔBCD
∠BAD = ∠BCD
So ∠BCD = 58°

2. Power of variable e is 3. So, it is not a linear equation
No.
3) Great than symbol is there. No, it is not a linear equation.

Which of the sets of ordered pairs represents a function? (5 points)
A = {(3, −5), (4, 6), (−3, 9), (2, 7)}
B = {(2, 4), (−1, −7), (5, 6), (4, 3)}
Answers
Unless you mistyped the first number and it’s actually -3 instead of 3 than b is the answer.
To see if they make a function you can graph all the coordinates and do the line test. Or you can look at all the numbers and see if any of the ordered pair have repeating x values. If they do, it’s not a function.
Remember, it’s (x,y) and if any X values repeat, it’s NOT a function
If the slope of a line and a point on the line are known, the equation of the line can be found using the slope-intercept form, y = mx + b. To do so, substitute the value of the slope and the values of x and y using the coordinates of the given point, then determine the value of b. Using the above technique, find the equation of the line containing the points (-4,7) and (2,-2).
What is the equation of the line?
(Simplify your answer. Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation.)

If x + y = 10 and x - y = 4, find the value of x² - y²
Answers
Answer:
x²-y² = 40
Step-by-step explanation:
Factorising x²-y²:
x²-y² = (x+y)(x-y)
This is due to the property that states:
a²+b² = (a+b)(a-b)
Substituting the given values into the above equation:
x²-y² = (10)(4)
= 40
Hence, x²-y² = 40

Evaluate 4.56 × 3.6/ 0.12 and leave you answer in standard form.
Answers
Answer:
136.8
Step-by-step explanation:
As per DMAS rule, we can divide first or multiply first. I would choose divide first. Then:
4.56 x 3.6/0.12
= 4.56 x 30.
Since I divided first, the next step is to multiply.
4.56 x 30
= 136.8
Since there is no addition or subtraction happening next, the process ends here and the answer is 136.8.
Kind requests:
Please give me brainliest if this was helpful.
The expression value [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10².
To evaluate the expression [tex]4.56 \times \frac{ 3.6}{0.12}.[/tex]
Find the multiplication of the numerator with 4.56 and then divide it by 0.12.
Perform the multiplication first:
4.56×3.6 = 16.416
Now we divide the result by 0.12:
[tex]\frac{16.416}{0.12} = 136.8[/tex]
To express the answer in standard form, we rewrite it as a number multiplied by a power of 10.
In this case, we move the decimal point two places to the right to obtain a whole number:
136.8=1.368×10²
Therefore, the answer to the expression [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10²

Write an equation in slope-intercept form for the line described. Write the slope and y-intercept as fractions, if necessary. passes through (6, 2), parallel to y = -}x+1
Answers
The slope of your answer will be whatever number is supposed to be in front of the x (assuming you hit the close brace on accident the same time you hit the minus sign, I’m gonna assume you meant to put -x+1) making the slope of your answer -1.
So you have y=-x+b
To find b, plug in (6,2)
2 = -(6) + b
8 = b
So, your answer would be
y = -x + 8
Otherwise, whatever is suppose be in front of the x,
y = -mx + (2+6m)

How do you solve this
Answers
Answer:
x = 8
Step-by-step explanation:
1. First, we should realize that the angle with 16x + 7 and the angle with 5x + 5 are same-side interior angles, meaning they add up to 180 degrees. This means that 16x + 7 + 5x + 5 = 180.
2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](16x+5x)+(7+5)=180[/tex] [tex]21x + 12 = 180[/tex]Step 2: Subtract 12 from both sides.
[tex]21x + 12 - 12 = 180 - 12[/tex] [tex]21x = 168[/tex]Step 3: Divide both sides by 21.
[tex]\frac{21x}{21}=\frac{168}{21}[/tex] [tex]x = 8[/tex]Step 4: Check if solution is correct.
[tex]16(8)+7+5(8)+5=180[/tex] [tex]128 + 7 + 40 + 5 = 180[/tex] [tex]135 + 40 + 5 = 180[/tex] [tex]175 + 5 = 180[/tex] [tex]80= 80[/tex]Therefore, x = 8.
