Answer:

-2x - (-1y) - (-3)

Step-by-step explanation:

Answer:

-2x + y + 5

Step-by-step explanation:

(5x - 2y + 1) - (7x - 3y - 4)

1) Distribute the negative sign and remove all parenthesis

5x - 2y + 1 - 7x + 3y + 4

2) Combine all like terms

-2x + y + 5

Answer:

38 °

Step-by-step explanation:

a triangles total side add up to 180°

so, we subtract 180 - 106 = 74

then we subtract 74-36 = 38°

?= 38°

Given that,

An equation : -9c² +2c +3 = 0

To find,

Find the value of x.

Solution,

We have, -9c² +2c +3 = 0

We can solve it using the formula as follows :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Here, a = -9, b = 2 and c =3

Put the values,

[tex]c=\dfrac{-2\pm \sqrt{(2)^2-4(-9)(3)}}{2(-9)}\\\\c=\dfrac{-2+\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}, \dfrac{-2-\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}\\\\c=-0.47, 0.69[/tex]

So, the solution are -0.47 and 0.69.

Answer:

B. The other solution to function [tex]h[/tex] is [tex]-4-i\,7[/tex].

Step-by-step explanation:

From Algebra, we remember that quadratic functions of the form [tex]a\cdot x^{2}+b\cdot x + c[/tex] has solutions of the form:

[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], where both are complex if and only if [tex]\sqrt{b^{2}-4\cdot a \cdot c}< 0[/tex].

Hence, if one solution of the quadratic function is [tex]-4+i\,7[/tex], then the other solution is [tex]-4-i\,7[/tex]. The correct answer is B.

Answer:

Option (4)

Step-by-step explanation:

By applying triangle sum theorem in ΔABC,

m∠A + m∠B + m∠C = 180°

80° + 40° + m∠C = 180°

m∠C = 180° - 120°

m∠C = 60°

Since, ∠ACB ≅ ∠DCE [Vertically opposite angles]

m∠DCE = m∠ACB = 60°

Now by applying triangle sum theorem in ΔCDE,

m∠DCE + m∠CED + m∠CED = 180°

60° + 70° + x° = 180°

x = 180 - 130

x = 50°

Therefore, Option (4) will be the answer.

Answer:

0.1538

Step-by-step explanation:

first convert 3/11 into a percentage

3÷11=0.272727272727273

0.272727272727273 × 100

27.272727272727/100

27.272727272727%

≈27.27%

27.27% of 22/39

change 22/39 into a decimal

22÷39=0.5641025641》0.564

27.27% of 0.564

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 27.27% * 0.564

Converting percent to decimal:

p = 27.27%/100 = 0.2727

Y = 0.2727 * 0.564

Y = 0.1538

Answer:

D. <C'D'A'

Step-by-step explanation:

Given that figure ABCD is transformed to figure A′B′C′D′, therefore the angles of ABCD would be congruent to the corresponding angles of A′B′C′D′.

<CDA corresponds to <C'D'A'. Therefore:

<CDA = <C'D'A'

Answer:

  128 ft

Step-by-step explanation:

The height of the tower above eye-height is related to the angle by ...

  Tan = Opposite/Adjacent

  tan(72°) = (tower height above eye height)/(40 ft)

  tower height above eye height = (40 ft)×tan(72°) = 123 ft

Since eye height is 5 ft, the total height of the tower from the ground is ...

  tower height = eye height + height above eye height

  tower height = 5 ft + 123 ft

  tower height = 128 ft

Hey there!

Given;

The points is; (-1 , 2) and slope is 4.

Note: Use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

~ Put all values.

[tex](y - 2) = 4(x + 1)[/tex]

~ Simplify it.

[tex](y - 2) = 4x + 4[/tex]

[tex]4x - y + 6 = 0[/tex]

Therefore, the required equation is; 4x-y+6=0.
