Answer:
D) 2x² + x - 10
Step-by-step explanation:
First, distribute the negative sign to all terms within the second parenthesis:
- (4x - x² + 6) = -4x + x² - 6
Next, combine like terms:
5x + x² - 4 - 4x + x² - 6
(x² + x²) + (5x - 4x) + (-4 - 6)
2x² + x - 10
2x² + x - 10 , or D) is your answer.

y is inversely proportional to x.when y=7 x=9 a) work out an equation connecting y and x b) work out the value of y when x=21
Answer:
a) y = k/x
7 = k/9
b) y = 3
Step-by-step explanation:
From the question, we are told that:
y is inversely proportional to x.
Mathematically:
y ∝ 1/x
y = k × 1/x
y = k/x
k = Constant of Proportionality
a) work out an equation connecting y and x
To find this Equation,
y = k/x
when y=7 x=9
Hence:
7 = k/9
b) work out the value of y when x=21
We find the value of k first
7 = k/9
k = 7 × 9
k = 63
Hence, the value of y when x=21
y = k/x
k = 63, x = 21
y = 63/21
y = 3

Step-by-step explanation:
The diagram shows two right-angled triangles. Calculate the value of x.
The value of x in the given diagram is 7cm.
What is tangent of an angle?The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
According to the given question.
We have a diagram in which we have two right angled triangles.
Now, in the upper right angled triangle
[tex]tan50 = \frac{0pposite side}{5}[/tex]
⇒ 1.19 = 0pposite side/ 5
⇒ opposite side = 1.19 × 5
⇒ opposite side = 1.2 × 5
⇒ opposite side = 6cm
Now, the opposite side w.r.t angle 50 degrees in the upper right angle triangle is a adjacent side w.r.t to angle 38 degrees in the lower right angle triangle.
So, in the lower right angle triangle.
[tex]tan38 = \frac{x}{adjacent side}[/tex]
⇒[tex]0.78 = \frac{x}{6}[/tex]
⇒ x = 0.78 × 6
⇒ x = 4.68
⇒ x = 7cm
Hence, the value of x in the given diagram is 7cm.

Answer:
25
Step-by-step explanation:
Given,
Measurement of <1 = x + 10
Measurement of <2 = 4x + 5
Also, said in the question that both these angles are complementary.
Therefore, by the problem,
<1 + <2 = 90°
=> x + 10 + 4x + 5 = 90
=> x + 4x + 10 + 5 = 90
=> 5x + 15 = 90
=> 5x = 90 - 15 = 75
[tex] = > x = \frac{75}{5} [/tex]
=> x = 15
Now, we have got the value of x so,
Measurement of <1 is
<1 = x + 10 = 15 + 10 = 25 (Ans)
