Answer:
x = -5/4, x= -7
Step-by-step explanation:
Using the zero product property to solve this equation,
4x+5 = 0
4x = -5
4x/4 = -5/4
x = -5/4
x+7 = 0
x = -7
17 + x = 6 please help need fast
Answer:
x= -11
Step-by-step explanation:
17 + x = 6
Get x by itself on the left side of the equal sign by doing the opposite of (+) which is (-)
So subtract 6 - 17 = -11
So now we have:
x = -11
This is true:
17 + (-11) = 6
17 - 11 = 6
6 = 6
Answer: x = - 11

What is the approximate measure of angle T in the triangle below?
2.7 cm
3.9 cm
4.3 cm
[Not drawn to scale)
Answer:
Angle T = 79°
Step-by-step explanation:
From the question given above, the following data were obtained:
Side opposite U (u) = 2.7 cm
Side opposite S (s) = 3.9 cm
Side opposite T (t) = 4.3 cm
Angle T =?
The value of angle T can be obtained by using cosine rule as illustrated below:
t²= s² + u² – 2suCosT
4.3² = 3.9² + 2.7² – 2 × 3.9 × 2.7 × Cos T
18.49 = 15.21 + 7.29 – 21.06 × CosT
18.49 = 22.5 – 21.06 × CosT
Rearrange
21.06 × Cos T= 22.5 – 18.49
21.06 × Cos T = 4.01
Divide both side by 21.06
Cos T = 4.01 / 21.06
Cos T = 0.1904
Take the inverse of Cos
T = Cos¯¹ 0.1904
T = 79°

Please help me with this one, I’m really stuck on it.
7) Give the equation of a line that goes through (-3,8) with a slope of 2.
Answer:
y=2x+14.
Step-by-step explanation:
1. the equation of the required line in slope-interception form is:
y=s*x+i, where s - slope, i - interception;
2. according to the condition s=2, then the required equation is:
y=2x+i;
3. if the point (-3;8) belongs to the required line, it is possible to substitute their coordinates into the required equation and calculate the value of 'i':
8=2*(-3)+i; ⇒ i=14.
4. if s=2 and i=14, then the required equation of the line is:
y=2x+14.
A school has $500,000 to spend on technology. The school bought 400 laptop computers for $677 each, 20 printers for $93.49 each, and 10 scanners for $115.65 each. How much money does the school have left to spend on technology?
Answer:
500000-(400*677)-(20*93.49)-(10*115.65)=226173.7
Step-by-step explanation:
Money left 226173.7 usd
Answer:
$226,173.70
Step-by-step explanation:
400 * 677 = 270,800
20 * 93.49 = 1869.80
10 * 115.65 = 1156.50
270,800 + 1869.80 + 1156.50 = 273,826.30
500,000 - 273,826.30 = 226,173.70

Madge leaves her home at 8:05 to go to school. The drive takes one-third hour each way. If she is at school for 7 hours, what time does she arrive home?
1/3 of an hour is 60/3 = 20 minutes.
8:05 + 20 minutes = 8:25
8 :25 + 7 hours = 3:25
3:25 + 20 minutes = 3:45
She arrives home at 3:45
Answer:
3:45
Step-by-step explanation:
8.05 + .20 = 8.25
8.25 + 7 = 15.25
Change from military time to standard time.
3.25 + .20 = 3.45
3:45

Answer: 1.25 or 1 ¼
Step-by-step explanation:
This is because volume is (length x width x height).
So you would take (5 ½ times 2 ½ time 9).
This would give you 123.75 or 123 ¾.
Then you would take (125 - 123.75).

2. Decide whether the exercise involves permutations or combinations, and then solve the problem.
In a club with 7 male and 11 female members, how many 6-member committees can be chosen that have
(a) all men?
(b) all women?
(c) 4 men and 2 women?
Does the problem involve permutations or combinations?
Answer:
I think they are all combination because order doesn't matter but I don't have a calculator with me to give you EXACT answers for all of them
Step-by-step explanation:
I think combinations because order doesn't matter; or it isn't mentioned. I could be wrong as I'm still learning and confused with finite as well. But to do these, you would do the formula of the probability of an event which is E= favorable outcome/total probabilities.. so for all men 7c6/18c6 and then do the same thing for the rest but for the right ratios and whatnot.

Airport A is located on a coordinate plane at (-18, 14). Airport B is located at (8, 14). How far apart are the airports?
Answer:
26 units
Step-by-step explanation:
Use the distance formula, d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2[/tex]
Plug in the points:
d = [tex]\sqrt{(-18 - 8)^2 + (14 - 14)^2[/tex]
Simplify:
d = [tex]\sqrt{(-26^2 + (0)^2}[/tex]
d = [tex]\sqrt{676}[/tex]
d = 26
So, the airports are 26 units apart
