Answer:
x = -5 & x = -2
Step-by-step explanation:
x^2 + 7x +10 = 0 you takeaway 9 as quadratic equations have to equal 0
(x+5)(x+2) = 0 you find 2 numbers that go into 10 that add to make 7 and multiply to make 10
(x+5) = 0 so x =-5 & (x+2) = 0 so x =-2

x = 1.8
Step-by-step explanation:
Given
2.5(10x - 16) = 5 ( divide both sides by 2.5 )
10x - 16 = 2 ( add 16 to both sides )
10x = 18 ( divide both sides by 10 )
x = 1.8

Answers
Answer:
a=5.1
Step-by-step explanation:
Isolate the variable by dividing each side by the factors that don't contain the variable. Hope this helps! :)
The value of a, if The expression 2.4x − 3.9y − 1.2x + ay is equivalent to 1.2x + 1.2 y is 5.1.
What is an expression?A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.
Given:
2.4x−3.9y−1.2x+ay is equivalent to 1.2x+1.2y,
2.4x − 3.9y − 1.2x + ay = 1.2x + 1.2y
Simplify the above expression as shown below,
2.4x − 1.2x + ay - 3.9y = 1.2x + 1.2y
1.2x + y(a - 3.9) = 1.2x + 1.2y
As the expression is equivalent, compare the expression as shown below,
a - 3.9 = 1.2
a = 1.2 + 3.9
a = 5.1
Thus, the value of a is 5.1.

Answers
Answer:
$1130.30
Step-by-step explanation:
Step one:
given data
cost of computer= $2500
rate of loss per year= 18%
time t= 4 years
Step two:
let us computer the loss per year
Year 1 loss
worth= 2500- 2500*0.18
worth= 2500-450
worth= $2050
Year 2 loss
worth= 2050- 2050*0.18
worth= 2050-369
worth= $1681
Year 3 loss
worth= 1681- 1681*0.18
worth= 1681-302.58
worth= $1378.42
Year 4 loss
worth= 1378.42- 1378.42*0.18

5 forks2 spoonsStep-by-step explanation:
The higher-cost item is forks, so we can let x represent the number of those that are purchased. The total number purchased is 7, so the number of spoons purchased is (7-x).
The total cost is the sum of the costs for each of the items:
6x +5(7-x) = 40
x +35 = 40 . . . . . . simplify
x = 5 . . . . . . . . . . . subtract 35; the number of forks
7-x = 2 . . . . . . . . . the number of spoons
Daniel bought 5 forks and 2 spoons.
_____
Additional comment
Since $40 is not divisible by $6, we can guess that the number of forks Daniel bought will be a multiple of 5. That is, Daniel bought 0 or 5 forks. If he bought 0 forks, then he must have bought 40/5 = 8 spoons, so that is not a viable choice. The only number of forks that makes sense in this problem is 5 forks, so 2 spoons--numbers that total 7, as required.

X, Y and Z are three points on a map. Y is 75km and on a bearing of 200° from X. Z is on a bearing of 150°, from Y. Z is due south of X. Calculate the distance between X and Z rounded to 1 DP.
Answers
Answer:
The distance between X and Z is approximately 114.9 km
Step-by-step explanation:
The given parameters are;
The distance of Y from X = 75 km
The bearing of Y from X = 200°
The bearing of Z from Y = 150°
The bearing of Z from X = 180°
In triangle XYZ, we have;
∠YZX = 180° - (130° + 20°) = 30°
By sine rule, we have;
(75 km)/sin(30°) = XZ/(sin(130°))
XZ = sin(130°) × (75 km)/sin(30°) ≈ 114.9 km
The distance between X and Z ≈ 114.9 km. to one decimal place.

Answer:
Step 1, all the exponents are increased by 4
Step-by-step explanation:
The first incorrect step occurred in Step 1, where all the exponents were increased by 4.
This is mathematically incorrect due to exponential rules. When distributing exponents inside parentheses, we have to multiply the existing exponents inside the parentheses by the exponent outside the parentheses.
For example, (x²)³ is not x²⁺³, but rather, x⁽²⁾⁽³⁾.
We multiply the exponents instead of adding them together.
Therefore, the correct Step 1 should multiply all the variables' exponents by 4.
Steps 2 and 3 are correct since we do add the exponents when multiplying exponents with the same base, and we do subtract exponents with the same base when dividing.
