Answer:
x = ±3
Step-by-step explanation:
2 = |x| - 1
Add 1 to both sides: |x| = 3
⇒ x = ±3
Solution:
2 = |x| - 1Remember, the number inside the absolute value bars will always be positive. This means that if -5 is between two bars, it will become 5.
=> 2 + 1 = |x|=> 3 = |x|Let's review 2 ways that this equation can go through:
(3 = |3|) = (3 = 3) True(3 = |-3|) = (3 = 3) TrueHence, the measure of x is ±3.

Answer:
1.6 < x < 9.6
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
5.6 - 4 < x < 5.6 + 4
1.6 < x < 9.6
find the value of x please help
Answer:
x=37
Step-by-step explanation:
Area of triangle = x+x+x=180
= 78+65+x=180
=143+x=180
=x=180-143 (bring 143 to the otherside)
x=37
In the given figure, We are to find the respective value of x .
Solution :
We know that,
Sum of all the angles of the triangle = 180°
So,
[tex] \qquad \sf \dashrightarrow{ x {}^{ \circ} + 65 ^{ \circ} +78 ^{ \circ} = 180}[/tex]
[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} + 143^{ \circ} = 180^{ \circ}}[/tex]
[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} = 180^{ \circ}} - 143^{ \circ}[/tex]
[tex] \qquad \bf \dashrightarrow{ x ^{ \circ} = 37^{ \circ}}[/tex]
Therefore, The value of x is 37°

y= -5x _
y=-7x-14
—————— (y-y=-5x-(-7x)-14)....
0=-2x-14 => x=-7 => y=-5*(-7)=35
Answer: x = -7 and y = 35
Step-by-step explanation: STEPS USING SUBSTITUTION
y= -5x
y= - 7x - 14
consider the first equation. Add 5x to both sides.
y + 5x = 0
consider the second equation. Add 7x to both sides
y + 7x = -14
to solve a pair of equations using substitution, first solves one of the equations for one of the variables then substitute the result for that variable in the other equation. and so goes on

What is the area of the base? ( 1 point) Explain or show your reasoning. (2 points)
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².
VolumeVolume is the amount of space occupied by a three dimensional shape or object.
Area of triangle = (1/2) * DF * height
Height = 10 - 6 = 4 mm, DF = AC = AB + BC = 2 + 3 = 5 mm
Area of triangle = (1/2) * 5 * 4 = 10 mm²
Volume of triangle prism = Area of triangle * AG = 10 * 4 = 40 mm³
Volume of rectangular prism = A to F * AC * AG = 6 * 5 * 4 = 120 mm³
Volume of crystals = 120 + 40 = 160 mm³
Area of base = AC * AG = 5 * 4 = 20 mm²
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².

Find the area of the shaded area. Round your answer to the nearest tenth
Answer:
45π
Step-by-step explanation:
To find the area of a circle the formula is πr².
To find the shaded region we will subtract the area of the small circle from the area of the big circle.
Area(big circle)=π9²=81π
Area(small circle)=π6²=36π
81π-36π= 45π
Volume of 8 and the product of 5 and q increased by 6 yeilds
88
Answer:
It could be either of two ways:
8
x
+
10
or
8
(
x
+

)
Explanation:
The wording is a little unclear because this could be done in two ways:
8
x
+
10
or
8
(
x
+
10
)
The first one is "the product of 8 and a number, increased by 10"
The second is "the product of 8, and a number increased by 10"
The one you might write depends on how you say the statement!
In either case, when you read the phrase "a number" in algebra, you make this the variable - whatever letter you prefer (does not have to be
x
!)
Step-by-step explanation:
The verbal statement of the given algebraic expression gives us; 5(q + 6) = 88
How to write Algebraic expressions?
Now, we are told that the product of 5 and q increased by 6 yields 88. Thus, the expression gives us;
5(q + 6) = 88
Therefore we can conclude and say that the verbal statement of the algebraic expression gives us;
5(q + 6) = 88

What percentage of the apples are green?
Answer:
6 of the 30 apples are green
6 / 30 = .2
So 20% of the apples are green.
Percentage of the apples are green is 20%
What is a percentage?
"A Percentage is a number or ratio that represents a fraction of 100. It is often denoted by the symbol %".
According to the question
Total Apples = 30
Red Apples = 24
Green Apples = 6
Percentage of the apples are green = [tex]\frac{6}{30}[/tex]×[tex]100[/tex]
= [tex]20[/tex] % or [tex]0.2[/tex]

What is the slope of the line?
3(y - 1) = 2x + 2
Rewrite the equation in slope- intercept form.
3(y-1) = 2x + 2
Use the distributive property
3y-3 = 2x + 2
Add 3 to both sides
3y = 2x + 5
Divide both sides by 3
Y = 2/3x + 5/3
Slope = 2/3
Is it possible to have a polygon with an exterior angle of 14 degrees
Answer:
No, a polygon cannot have a decimal number of sides.
Explanation:
exterior angle of a polygon = 360 ÷ number of sidesusing the formula:
14 = 360 ÷ number of sides
1/number of sides = 14/360
number of sides = 360/14
number of sides = 25.71428571
Answer:
all polygons have exterior angles that totL to 360 degrees from triangles to 20-gons. so 360 divided by 14 is 25.71 sides which is not possible because what would .71 of a side look like....now this is assuming that you were referring to regular polygon with all sides the same. I suppose you could gave a polygon with a whole number of sides but the relationship between the exterior angles could be such that not all of the angles have the same degree measure. I would say that an exterior angle for any polygon would need to be greater than 0 but less than 360. so my answer is yes it could be possible le

Step-by-step explanation:
5x²+2x-4=0
D=2^2-4*(-4)*5=4+80=84
x1,2 = (-2±√(84))/10
x1= (-2+√(84))/10 = (-2+√(4*21))/10 = (-2+2√(21))/10 = (-2(1-√(21))/10 = -(1-√(21))/5

What is the percent of change from 8 to 4?
Answer:
50% decease
Step-by-step explanation:
A change from 8 to 4 represents a negative change (decrease) of -50%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent = New - Old/Old x 100
Percent = 4-8/8 x 100
Where: 8 is the old value and 4 is the new value. In this case we have a negative change (decrease) of -50 percent because the new value is smaller than the old value.
Hence, 50% decrease
Check Answer:
8 x 50% = 4
8 - 4 = 4
Hence, 50% decrease is the correct answer.

is there an equal sign between 9 and 10 or it's just a minus sign?
I mean if it is a minus sign the first thing to do to solve the equation is 9-10 which gives you -1. but if there is an equal sign the first step is to subtract 10 from both sides of the equation which means your answer will be option B.
