Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143
Jaden construction scale model of a building with a rectangle or a base model is 2 inches in length and 1 inch in with the scale of the model of 1 inch equals 47 feet what is the actual area in square feet of the base of the building

solve (200 + 200) √100
Answer:
4000
Step-by-step explanation:
200 + 200 {100
400 × 10
4000
Answer:
4000
Step-by-step explanation:
because the 200+200 are in parenthesis that shows that you will need to do it first.
so.. 200+200=400
and now the second part is asking for the square root of 100. We know that 10 times 10 is 100. This means that 10 is the square root of 100.
And for our last step they ask to multiply our two answers.
so 400 x 10= 4000

please help me with retake questions? im really confused
Answer:
20°
Step-by-step explanation:
It's a catch. Draw a stronger line (along the circle) from V, going through Z, W, X, and getting to Y. That measures 320°.
Since the whole circle is 360° the segment YV measures 40°. Therefore, angle VXY = 20°.

Teachers were told that next year they would receive a percent increase in their salary. Mrs. Bennett is making $32,000 a year and will receive $2,550.00 more next year. What is the percent increase? Round to the nearest percent. I need this answer ASAP please and thank you!
Answer:
7.97%
Step-by-step explanation:
Given data
Original Salary= $32,000
Increase= $2,550.00
percent increase= increase/original *100
Percent increase= 2,550.00/32000*100
Percent increase= 0.0796875*100
Percent increase= 7.97%
Hence the increase is 7.97%

Step-by-step explanation:
11/4 -7/6
33/12 - 14/12
19/12
1 7/12
Answer:
1 3/4 - 1 1/6
= 10/4 - 7/6
Lcm of 4 and 6 = 2 ×2 × 3 = 12
= (10/4) × 3 = 30/12
(7/6) × 2 = 14/12
30/12 - 14/12 = 30-13/12 = 17/12

the perimeter of an equalatrial triangle is 45m.what is the length of one side
Answer:
The length of one side is 15 cm
Step-by-step explanation:
In an equilateral triangle
perimeter (p) = 45 m
As we know that all three sides are equal in an equilateral triangle so, Let the length be l then
3l = p
3l = 45
l = 15 cm

Find the intersection points of the linear and quadratic functions shown below f(x)=2x-5 g(x)= x2+2x-21
Answer:
[tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.
Step-by-step explanation:
Intersection point of two functions is a common point which satisfies both the functions.
Given functions are,
[tex]f(x)=2x-5[/tex]
[tex]g(x)=x^2+2x-21[/tex]
For a common point of these functions,
[tex]f(x)=g(x)[/tex]
[tex]2x-5=x^2+2x-21[/tex]
[tex]-5=x^2-21[/tex]
[tex]0=x^2-16[/tex]
[tex]x^2=16[/tex]
[tex]x=-4,4[/tex]
For [tex]x=-4[/tex],
[tex]f(-4)=g(-4)=2(-4)-5[/tex]
[tex]=-13[/tex]
For [tex]x=4[/tex],
[tex]f(4)=g(4)=2(4)-5[/tex]
[tex]=3[/tex]
Therefore, [tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.

cos²x - sin²x = 0,66
x = 24.35°
Step-by-step explanation:
Recall that
cos²x - sin²x = cos 2x
which means that
cos 2x = 0.66 ---> 2x = cos^-1 (0.66) = 48.7°
or x = 24.35°
Answer:
x = 24.35, 155.65, 204.35, 335.65 degrees ( for 0 < x < 360 degrees).
Step-by-step explanation:
cos²x - sin²x = 0.66
cos^2 x = 1 - sin^2 x so
1 - sin^2 x - sin^2 x = 0.66
1 - 2sin^2 x = 0.66
2sin^2 x = 1 - 0.66
sin^2x = 0.34/2 = 0.17
sin x = +/- √0.17
= +/- 0.41231
x = 24.35 degrees ( in first quadrant)
and 180 + 24.35 = 204.35 degrees in third quadrant.

Review the graph of function h(x).
What is lim h(x), if it exists?
Answer:
0
Step-by-step explanation:
because you have to look at what both sides of the graph is doing as it approaches 2.
from the left, we can see the the graph is going down All the way to 0 at x=2.
and from the right side, the graph is going up to 0 at x=2.
therefore the graph is approaching 0.
The limit of h(x) as x tends to 2 is equal to 0.
How to get the limit of h(x) when x tend to 2?
Remember that a limit is not the same as an evaluation, the limit studies the behavior of the function near the value, not in x = 2.
While we can see that h(2) = 3 (we have a jump there). We can see that around x = 2 the function tends to zero.
From that, we conclude that:
[tex]\lim_{x \to \ 2} h(x) = 0.[/tex]
Then the correct option is the first one.

Step-by-step explanation:
68+62=130 then subract 180-130 and have 50 so x=50
Answer:
x°=50°
Step-by-step explanation:
Because of the Vertical Angle Theorem, the blank angle across from 68° is the same measure. Therefore, since the blank angle is 68°, then x° would be 50° because 180-62-68=50 due to the Triangle Angle Sum Theorem.
