Answer: v = -2
Step-by-step explanation:
-5v - v = 12
-6v = 12 [Divide -6 from both side]
v = -2
Solve for w. 6w+8w-2w-3=9w-24
A: w=-7
B: w=-1
C: w=7
D: w=1
Answer:
[tex]A. w=-7[/tex]
Step-by-step explanation:
First let's put our equation
[tex]6w+8w-2w-3=9w-24[/tex]
Combine like terms[tex]12w-3=9w-24[/tex]
Subtract [tex]9w[/tex] from both sides
[tex]3w-3=-24[/tex]
add [tex]3[/tex] to both sides
[tex]3w=-21[/tex]
Divide both sides by 3
[tex]w=-7[/tex]
Consider the function f(x) = x2 + 2x – 15. What are the x-intercepts of the function?
Step-by-step explanation:
X intercept, y = 0
x² + 2x - 15 = 0
x² + 5x - 3x - 15 = 0
x(x + 5) - 3(x + 5) = 0
(x + 5)(x - 3) = 0
x = -5 and x = 3
X - Intercept = (-5 , 0) and (3 , 0)
Answer:
Step-by-step explanation:
x^2 + 2x - 15 = 0
(x - 3)(x + 5) = 0
x = 3 or x = -5
left-most x-intercept: (-5, 0)
right-most x-intercept: (3, 0)
Someone pls help me on this I’m stuck on b
Answer:
a) 60
b) about 5%
Step-by-step explanation:
a)It appears that the "Over 60" segment is half the circle. Since the whole circle represents 120 people, half the circle will represent ...
1/2(120 people) = 60 people
__
b)We expect a table or an angle measure to be provided along with the pie chart. In the absence of those clues, we must make an attempt to measure the angle of the "Under 25" sector. We're not sure how you're expected to do that. Perhaps you're to hold a protractor up to the computer screen.
Our attempt shows it to be 19°. (We expect it to be a multiple of 3°, since 120 people are represented by 360°.) Expressed as a percentage of the whole, this is ...
19°/360° × 100% = 5.277...% ≈ 5% . . . . of villagers are Under 25

Additional comment
Measuring angles on a photograph is always tricky, because it is difficult to judge the effect of distortion on the angle being measured. Here, the picture is clearly taken at an angle to the screen, so we cannot be sure that the geometry is fairly represented by your attachment to the question.
These days, computer screen technology can render an image without much geometric distortion, so your best bet is to make a measurement on the screen. (This can actually be quite difficult on a touch-sensitive screen.) Printing the image introduces distortions of its own, so measurements from a printed copy may also have issues.

suppose y varies directly with x and y=4 when x=-2
Answer:
the answer is x8
Step-by-step explanation:
the answer is x8
Answer:
y = -2x
Step-by-step explanation:
The appropriate "direct variation" rule (formula) is y = kx.
Since y = 4 when x = -2, 4 = k(-2), or k = -2
Then the specific formula relating x and y is y = -2x

How to construct a triangle if Perimeter and base angle - 15 units, 55° and 60°
Explanation:
In the usual sense of the term "construct", it is impossible to create a triangle with the given measures. A ruler of some sort must be used in order to make it have the given perimeter. That means you're not doing the construction with a compass and (unmarked) straightedge.
Similarly, it is impossible to "construct" a 55° degree angle. Such an angle can be created using a protractor. (Angles that are multiples of 7.5° can be constructed, but 55° is not one of them.)
__
To make the perimeter be 15 units, at least one of the side lengths must be known. The side lengths will be proportional to the sines of the angles, so the scale factor for that can be found as ...
k = 15/(sin(55°) +sin(60°) +sin(65°)) ≈ 15/2.59148 ≈ 5.78819
Then the side opposite the 65° angle, between the 55° and 60° angles, will be ...
k·sin(65°) ≈ 5.24588 . . . . units
With this information, a ruler, and a protractor, the triangle of interest can be created.
(The first attachment is output from a triangle solver showing that the above measurements will result in a triangle with the desired perimeter.)
__
The steps could be as follows:
Using a ruler, create line segment AB of length 5.246 units. Using A as its vertex, mark an angle 55° from line AB, and draw its terminal ray. Using B as its vertex, mark an angle 60° from line AB, and draw its terminal ray. The intersection of those rays is point C of the desired triangle ABC. An example is shown in the second attachment.

Answer:
1. 23.46 ft^2
8. 73.8 ft^2
Step-by-step explanation:
Describe and correct the error in finding the solution.
-3x + 2 = -7
-3x = -9
-3x/3=-9/3
X=-3
-3x + 2 = -7 (given)
-3x = -9 (correct)
-3x/3 = -9/3 (incorrect, correct if -3x/-3 = -9/-3)
x = -3 (incorrect, if -3x/3 then -x = -3 not x = -3. From -x = -3 we need to do -x/-1 and -3/-1 which would be x = 3)
Answer:
in step 3 we forgot the negative sign so it is x=3

two numbers differ by 8 their product is 65 find the numbers
Answer:
5, 13
Step-by-step explanation:
a - b = 8
ab = 65
= 5 * 13
13 - 5 = 8
Answer:
Both solutions fit the description. Either the numbers are -5 and -13, or they are 5 and 13.
Step-by-step: Numbers m and n.
Differ by 8: n-m=8
Product is 65: m n=65
Find m and n.
The Differ equation gives n=m+8. Use this in the Product equation.
m(m+8)=65
m^2+8m-65=0, which we can factor, so let's do that:
(m+5)(m-13) ---- will that work? No. Gives -8m instead of +8m.
(m-5)(m+13) ---- Will that work? Yes. 13m-5m=8m, and product in const. term is -65.
OKAY, solution to the quadratic formed is m=5 or m=-13.
What about n?
n-m=8
n=m+8
For m=5, n=13.
For m=-13, n=-5.
is 3 + x + x^2 = 0 linear or non linear
Answer:
Step-by-step explanation:
linear eq. is of first degree.
x²+x+3=0
it is of degree 2 so it is non linear.
