Answer:
3x+4, x=2
3(2)+4
6+4=10
Hello there! :-)
To find the value of 3x+4 when x=2, all we have to do is substitute the value of 2 into the expression:
3x+4
3(2)+4
6+4
10
Therefore, the answer is 10.

Evaluate –32 + (2 – 6)(10).
Answer:
-49
Step-by-step explanation:
You want to evaluate the expression -3² +(2 -6)(10).
Order of operationsThe Order of Operations tells you the expression in parentheses is evaluated first, followed by the term containing the exponent.
-3² +(2 -6)(10) = -3² +(-4)(10)
= -9 +(-4)(10)
= -9 -40
= -49
The value of the expression is -49.
__
Additional comment
The leading minus sign applies to the result from the squaring operation. If the square of -3 is wanted, it is put in parentheses: (-3)² = 9.

Given the figure below, which statement correctly completes the following? ABE and HCD are what type of angles
Angles are classified based on their measures.
Classification of angles
The following are the classification of angles
Acute AnglesRight AnglesObtuse AnglesStraight linesReflex AnglesThe smallest angle is 0 degrees and the largest is 360 degrees.
When the measure of an angle is less than 90 degrees, such angle is an acute angle
When the measure of an angle is exactly 90 degrees, such angle is a right angle
Angles greater than 90 degrees, but less than 180 degree are obtuse angles, while angles that measure exactly 180 degrees are straight lines.
The last type of angle is the reflex angle, and it has a measure between 180 degrees and 360 degrees (exclusive)
The question is incomplete, so I gave a general explanation

Answer:
74.0 g/mol
Explanation:
Step 1: Write the generic neutralization reaction
HA + NaOH ⇒ NaA + H₂O
Step 2: Calculate the reacting moles of NaOH
At the equivalence point, 33.83 mL of 0.115 M NaOH react.
0.03383 L × 0.115 mol/L = 3.89 × 10⁻³ mol
Step 3: Calculate the moles of HA that completely react with 3.89 × 10⁻³ moles of NaOH
The molar ratio of HA to NaOH is 1:1. The reacting moles of HA is 1/1 × 3.89 × 10⁻³ mol = 3.89 × 10⁻³ mol.
Step 4: Calculate the molar mass of the acid
3.89 × 10⁻³ moles of HA have a mass of 0.288 g.
M = 0.288 g / 3.89 × 10⁻³ mol = 74.0 g/mol

Pls explain how to solve it!
Answer:
a = jd
Step-by-step explanation:
We want to solve for a given that a/d = j
To do so we want to isolate a (get a by itself )
We can do this by using inverse operations.
We would want to get rid of the d
A is being divided by d.
The inverse of division is multiplication so to get rid of the d we multiply a/d by d but whatever we do to one side we must do to the other so we multiply both sides by d
a/d * d = a
j * d = jd
we are then left with a = jd
And we are done!
Answer:
a = jd
Step-by-step explanation:
We have to solve the equation for a - in other words, we have to find a in terms of d and j. Another way to think about this is that we need a by itself on one side, equal to the other two values in some sort of relationship.
So, how can we accomplish this? Well, currently a is being divided by d, so we should probably multiply both sides by d to get that d away from a. The process is shown below:
[tex]\frac{a}{d} =j[/tex]
[tex]\frac{a}{d} *\frac{d}{1} =j*d[/tex]
[tex]\frac{ad}{d} =jd[/tex]
[tex]a=jd[/tex]
And look at that! We've solved for a in terms of the other two values. If you need any more help or everything I just did was confusing or overwhelming, let me know so I can clarify. :)

The area of the composite figuren as shown in the diagram is 90 in².
What is area?
Area is the region bounded by a plane shape.
To calculate the area of the figure, we use the formula below
Formula:
Area of the figure = Area of the rectangle+Area of the trapeziumA = aw+h(a+b)/2..................... Equation 1Where:
a = Length of the rectangle = Length of on of the side of the trapezium = 10 inb = Length of the other side of the trapezium = 6 inh = Height of the trapezium = 5 inw = Width of the rectangle = 5 inSubstitute these values into equation 1

Very important question ⁉️
Answer:
90°
Step-by-step explanation:
AB and CD are parallel lines and EF is reversal
Therefore angles BGH and DHG are consecutive interior angles
As we know the sum of consecutive interior angles equals to 180°:
∠BGH + ∠DHG = 180°
Line GP bisects angle BGH , therefore
m∠PGH = 1/2*m∠BGH
Line HP bisects angle GHD, therefore
m∠PHG = 1/2*m∠GHD
Sum of two angles of triangle GHP:
m∠PGH + m∠GHD = 1/2(∠BGH + ∠DHG) = 1/2*180° = 90°
Therefore the missing angle a is:
∠a = 180° - (m∠PGH + m∠GHD) = 180° - 90° = 90°

Evaluate the expression. 5 x (-6 / -1 + -10)
Answer:
-20
Step-by-step explanation:
PEMDAS
Parentheses -> Exponents -> Multiplication -> Division -> Addition -> Subtraction
1.) First, we can rewrite this equation to make it easier to understand
5 x (-6 / -1 + - 10)
5(-6 / -1 - 10)
2.) Begin by dividing inside the parentheses
5(-6 / -1 - 10)
5(6 - 10)
3.) Solve
5(6 - 10)
5(-4)
-20
or
5(6 - 10)
5(6) 5(-10)
30 - 50
-20
Therefore, the expression equals -20.

4/-1
-4/1
y-1=-4(x-3)
y-1=-4x+12
y=-4x+13
Answer:
[tex]y = -4x + 13[/tex]
Step-by-step explanation:
First, find the slope (denoted by the variable, m). Use the following equation:
slope [tex](m) = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1, y_1) = (4 , -3)\\(x_2, y_2) = (3 , 1)[/tex]
Plug in the corresponding numbers to the corresponding variables:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - (-3)}{3 - 4} = \frac{1 + 3}{-1} = \frac{4}{-1} = -4[/tex]
Use the slope-intercept form. The slope-intercept form is:
[tex]y = mx + b[/tex]
Use one of the given points to plug in for (x ,y). Also note that the slope (m) is equal to -4. Plug in the corresponding numbers to the corresponding variables:
[tex]y = mx + b\\(x , y) = (3 , 1)\\m = -4\\\\\\1 = (-4 * 3) + b\\1 = (-12) + b\\1 (+12) = b - 12 (+12)\\b = 1 + 12\\b = 13[/tex]
Plug in the slope (m) and the y-intercept (b) to get your equation:
[tex]y = -4x + 13[/tex]
