The teacher told her students that her age is "8 more than a, times 2." Write an expression to show the teacher's age.
Answer:
16 + 2a
Step-by-step explanation:
Since "a" is the missing variable, we need to set up an equation to express this.It says, "8 more than a" which means we add 8 to a.So far we have 8 + a = ?It says "times 2" so we multiply the expression "8 + a" by 2.Now we have 2(8 + a)We can reduce this by using distributive property.16 + 2aIf I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
Find the co-interior angle measurements for the measured angle.
?
Answer:
86°
Step-by-step explanation:
As we know that when a transversal intersects two parallel line , then the sum of co-interior angles is 180° . Hence here one of the two co-interior angles is 94° and we are are interested in finding the second one . So , let the unknown angle be x , then ;
[tex]\implies \rm x + 94^\circ = 180^\circ [/tex]
Subtract 94° from both sides,
[tex]\implies \rm x = 180^\circ -94^\circ[/tex]
Simplify,
[tex]\implies \rm \underline{\underline{x = 86^\circ}}[/tex]
Hence the required answer is 86°
Donna's car indicates that she is averaging 29.8 miles per gallon of gasoline. The GPS shows that she is 208.6 miles from her destination. How many gallons of gasoline will she use to get to her destination if she maintains the same speed?
Answer:
30.6
Step-by-step explanation:
First you will Subtract 208.6 to 29.8 gallons then you'll get your answer but your still need to divide the numbers you got when you subtracted to the miles from her destination then there's your answer
Write an equation for the line in slope-intercept form.
Answer:
y= -2x +3
Step-by-step explanation:
What is the slope-intercept form?• It is when the equation of a line is written as y= mx +c, where m is the gradient (or slope) and c is the y- intercept.
How can we find the equation of a line?• Two things are needed in order to find the equation of a line, namely
GradientA pair of coordinates (or a point in which the line passes through)Do note that in the case where the gradient of the line is not stated in the question, it can be obtained using the gradient formula as long as you have two pairs of coordinates. In the formula shown below, (x₁, y₁) is the first pair of coordinates while (x₂, y₂) is the second pair of coordinates.
[tex]\boxed{gradient=\frac{y_1 -y_2}{x_1 -x_2} }[/tex]
Working to question:Firstly, let's work out the gradient of the line! In order to do so, we need to identify 2 pairs of coordinates so that we can plug them into the gradient formula.
2 points identified: (0, 3) and (1, 1)
Using the gradient formula,
gradient
[tex]=\frac{3-1}{0-1}[/tex]
[tex]=\frac{2}{-1}[/tex]
= -2
Substitute the value of the gradient into the equation:
y= -2x +c
c is the y-intercept, which is the y-value in which the line cuts through the y-axis (i.e. occurs at x= 0). Since we have already identified the y-intercept, (0, 3), as one of our points, we can substitute the y-coordinate value into c.
y= -2x +3
In the case where the y-intercept cannot be identified from the graph, you can substitute a pair of coordinates in which the line passes through into the equation after the value of m has been substituted. After solving for c, substitute its value back into the equation and you will arrive at your answer.
y= -2x +c
When x= 1, y= 1,
1= -2(1) +c
1= -2 +c
c= 1 +2
c= 3
Thus, the equation of the line is y= -2x +3.

Solve the equation using the quadratic formula. 262 – 3b+85=-5
Answer:
b= 352/3
or b= 117.33
Step-by-step explanation:
262-3x+85=-5
-3x+(262+85)=-5
simplify the arithmetic
-3x+347=-5
Group all constants on the right side of the equation
-3x+347=-5
Subtract from both sides:
-3x+347-347=-5-347
Simplify the arithmetic:
-3x=-5-347
-3x=-352
isolate the x
-3x=-352
Divide both sides by -3
-3x/-3}=-352/-3}
Cancel out the negatives
3x/3}=-352/-3
Simplify the fraction
x= -352/-3
Cancel out the negatives
x=352/3

Answer:
angles one and two are supplementary angles and adjacent angles
Step-by-step explanation:
Definitions:
Supplementary angles: two angles that add to 180 deg
Adjacent angles: two angles that have a common side and a common vertex (corner point) and don't overlap
complementary angles: two angles that add up to 90 deg
vertical angles: two angles that are directly opposite from each other, formed by intersecting lines

What is the value of y?
Answer:
38°
Step-by-step explanation:
All triangles have a total degree of 180°.
The degrees added together would be 180°.
-------------------------------------------------------------------------------------------------------------
2y - 4 + 43 + 2y - 11 = 180°
4y + 28° = 180°
4y = 180° - 28°
4y = 152°
y = 38°

Answer:
Vertex: (7,-6)
Axis of symmetry: x = 7
Step-by-step explanation:
Hello!
Vertex:When given an absolute value equation, any number that is being added or subtracted to x in the absolute value brackets is the change in x
If a number is being added, the graph moves that many units to the left of the origin.
If a number is being subtracted, the graph moves that many units to the right of the origin.
Here, we have a subtraction of 7, so our x-coordinate becomes positive 7 (7 units to the right of the origin).
When a change is being added or subtracted outside of the absolute value brackets, it's the change in y. There is no reversing of the movement, so if there is a negative change, the vertex moves down, and if there is a positive change, the vertex move sup.
Our y-coordinate is -6 because we are subtracting 6.
Our vertex is at (7,6)
Axis of SymmetryThe axis of symmetry in an absolute value function is the x-value of the vertex.
Since the axis of symmetry is a vertical line, our x-value should be 7, so ultimately our axis is x = 7

How did the South’s economy contribute to conditions in prison camps later in the Civil War?
The expanding Southern economy led to gradual improvements in living conditions at the camps.
The expanding Southern economy allowed Union prisoners to more easily cooperate with their guards.
The deteriorating Southern economy forced Union soldiers to work as slaves in the camps.
The deteriorating Southern economy caused shortages of provisions at the camps
The South’s economy contribute to conditions because the deteriorating Southern economy forced the Union soldiers to work as slaves in the camps.
Who are the prisoner of of the Civil war camps?The prisoner of of the Civil war camps were forced to carry out slave labour on a starvation diet and hostile environment which caused many to died of malnutrition or disease.
Hence, the South’s economy contribute to conditions because the deteriorating Southern economy forced the Union soldiers to work as slaves in the camps.

PLEASE HELP!! A triangle has a height of 3 meters and an area of 9 square meters. Is there a unique triangle represented by these measurements?
Answer:
No
Step-by-step explanation:
Since the height is 3, the base much is equal to 6 because when you use the triangle area formula you get (3*6)/2 which is = 9. This also doesn't contain any uniqueness in a triangle.
