Answer:
to solve, really, you just combine like terms and follow the formula
Step-by-step explanation:
for example:
y2-y1=m(x-x1)
y-3=4(x-5)
y-3=4x-20
y=4x-23
Evaluate (18)^2-(15)^2
Please show working.
Answer:
99
Step-by-step explanation:
You can solve it by Squaring/multiply 18 by itself and 15 by itself then subtract them both:
(18 × 18) - (15 × 15)
324 - 225
99
You could also do difference of two squares:
(x² - y²)
= (x + y) (x - y)
= (18 + 15) (18 - 15)
= (33) (3)
= 99
Answer:
99Step-by-step explanation:
Evaluate
= (18)^2-(15)^2
= 324 - 225
= 99

Answer:
50
Step-by-step explanation:
180 - 90+40 = 50
Answer:
Answer: 50 degrees
Step-by-step explanation:
important things to know:the square in the bottom right means 90°all angles in a triangle add up to 180°using this knowledge, you can make the following equation:
90 + 40 + x = 180
130 + x = 180
now subtract 130 from both sides.
x = 180 - 130
x = 50°

Emerson needs an average of at least 90 points in order to earn an "A" in his science
class. So far, his test scores are 92, 86, and 88. What is the lowest grade Emerson can
score on his final test in order to earn an "A"?
s < 94, Emmerson must earn below a 94 on his final test to earn an "A" in his class.
b) s > 94, Emmerson must earn above a 94 on his final test to earn an "A" in his class.
c) s < 94, Emmerson must earn at most a 94 on his final test to earn an "A" in his class.
d) s 294, Emmerson must earn at least a 94 on his final test to earn an "A" in his class.
Answer:
D) Emerson must earn at least a 94 on his final test to earn an “A” in his class
Step-by-step explanation:
We calculate this using mean in this format:
Test Scores / # of Test ≥ 90 (which is an A)
Substitute:
(92 + 86 + 88)+ x / 4 ≥ 90
Add:
266 + x / 4 ≥ 90
Get Rid of the Denominator:
(4) 266 + x / 4 ≥ 90 (4)
Multiply:
266 + x ≥ 360
Isolate x (Subtract 266 From Both Sides):
x ≥ 94
This means that x (His final test score) has to be greater than (above) or equal to 94. A term for greater than or equal to is “at least.” Hope this helps :)

what is the value of n for the equation 1/3n=9
Answer: n = 27
Step-by-step explanation: n in (-oo:+oo)
(1/3)*n = 9 // - 9
(1/3)*n-9 = 0
1/3*n-9 = 0 // + 9
1/3*n = 9 // : 1/3
n = 9/1/3
n = 27

Select the correct answer from the choices given
(13 + 4i) + n = 0
What is n?
0
1
–13 + 4i
–13 - 4i
The value of n that makes the equation [tex](13 + 4i) + n = 0[/tex] true is (d) -13 - 4i.
The equation is given as:
[tex](13 + 4i) + n = 0[/tex]
Remove brackets
[tex]13 + 4i + n = 0[/tex]
Subtract 13 from both sides
[tex]13 - 13 + 4i + n = 0 - 13[/tex]
Evaluate like terms
[tex]4i + n = - 13[/tex]
Subtract 4i from both sides
[tex]4i -4i + n = - 13 -4i[/tex]
Evaluate like terms
[tex]n = - 13 -4i[/tex]
The equation cannot be further simplified.
Hence, the value of n is (d) -13 - 4i

Step-by-step explanation:
The shadow of a 5-foot tall post is 10 feet long. At the same time, a tree casts a shadow that is 24 feet long. What is the height of the tree?
A.
14 feet
В.
12 feet
C.
18 feet
D. 2 feet
Answer:
C. 12 feet.
Step-by-step explanation:
The lamp post has a shadow that's twice as long as it'a actual height. The tree's shadow is 24 feet long, so it would be 24/2, which is 12 feet.

Can anyone tell me
Answer:
9
Step-by-step explanation:
what is the slope or the line going through (0,0) (6,8) A: -6/8 B: -3/4 C: 3/4 D: 8/6
Start at (0,0). To get to the other point, you must move up 8 units and move to the right 6 units.
slope = rise/run = (change in y)/(change in x) = 8/6
Or you could use the slope formula
m = (y2-y1)/(x2-x1)
m = (8-0)/(6-0)
m = 8/6
Normally I would reduce, but your teacher has decided not to.
8/6 reduces to 4/3 when you divide both parts by 2.
find the selling price $280 tax 5%
Answer:
The selling price is $294
Step-by-step explanation:
5/100 (280)
0.05 * 280 = 14
5% of 280 equals 14.
To find the selling price we have to add the tax to the price.
$14 + $280 = $294
The selling price is $294
