Answer:
−2x^2−5x+3
Step-by-step explanation:
simplify
−4x^2 + 10 + 2x^2 −5x −7
= −4x^2 + 10 + 2x^2 + −5x +−7
combine like terms:
= −4x^2 + 10 + 2x^2 + −5x + −7
= (−4x^2 + 2x^2) + (−5x) + (10+ −7)
= −2x^2 + −5x + 3

The vertices of quadrilateral WXYZ are W(-1,4); X(3,5); Y(4,1); Z(00). What kind of quadrilateral is it? Explain how you know this. Be as specific as possible.
Answer:
This quadrilateral is a SQUARE.
When we plot these points, we realize that they are equal distance apart.
So, when a quadrilateral has sides that are equal distance apart, that quadrilateral is a square.

The observed bunny rabbit population on an island is given by the function p= −0.4t^2 + 130t + 1200, where t is the time in months since they began observing the rabbits. Write an algebraic inequality that expresses the question "when is the population greater than 9500?"
Answer:
[tex]-0.4t^2+130t+1200>9500[/tex]
Step-by-step explanation:
The given expression is
[tex]p=-0.4t^2+130t+1200[/tex]
where
[tex]p[/tex] = Population of rabbits
[tex]t[/tex] = Time in months
Now, the population is greater than [tex]9500[/tex]
So, the algebraic inequality that expresses the question "when is the population greater than 9500?" is
[tex]-0.4t^2+130t+1200>9500[/tex]
I Need help ASAP please and Thankyou!!
Answer:
Step-by-step explanation:
m∠R = 180° - 110° [Linear pair of angles are supplementary]
m∠R = 70°
m∠S = 45° [Vertically opposite angles]
By triangle sum theorem,
m∠P + m∠R + m∠S = 180°
m∠P + 70° + 45° = 180°
m∠P = 180 -115
= 65°
Therefore, m∠A = m∠P = 65° [Vertically opposite angles]
By triangle sum theorem,
m∠B + m∠S + m∠T = 180°
m∠B + 45° + 65° = 180°
[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]
m∠B = 180° - 110° = 70°
m∠C + m∠B = 180° [Linear pair of angles are supplementary]
m∠C = 180° - 70° = 110°
m∠D + m∠T = 180° [Linear pair of angles are supplementary]
m∠D + 65° = 180°
m∠D = 115°
Can you guys help me. l will give you the brainliest and if you give me the correct answers. please show working.
Answer:
Step-by-step explanation:
Angles formed when we turn clockwise in the given directions,
a) N to E → 90°
b). W to NE → (90° + 45°) = 135°
c). SE to NW → 180°
d). NE to N → 360° - 45° = 315°
e). W to NE → 90° + 45° = 135°
f). S to SW → 45°
g). S to SE → 360° - 45° = 315°
h). SE to SW → 180°
i). E to SW → 90° + 45° = 135°

Answer:
Step-by-step explanation:
either 1 foot or 33 ;-;
The value 5.1 feet long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
A string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.
Let the value is C.
The Pythagoras' theorem,
C² = (11)² + (12)²
C² = 121 + 144
C² = 265
C = 5.1 feet.
Therefore, the value is 5.1 feet.

please help solve!! i need my work need to me shown so please help me! ❤️
Answer:
56/19
Step-by-step explanation:
I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...
2X + 5(1.5X) = 8
2X + 7.5X = 8
9.5X = 8
19X = 16
X = 16/19
While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...
3X = 2Y
3(16/19) = 2Y
48/19 = 2Y
24/19 = Y
With the value of X and the value of Y, we can answer the question that's asked:
2X + Y = ?
2(16/19) + 24/19 =
32/19 + 24/19 =
56/19
Final Answer: 56/19
Answer:
[tex]x = - 1[/tex]

Apply elimination method. Let multiply the bottom equation by -3/2.
[tex]2 \times - \frac{3}{2} x = - 3[/tex]
[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]
[tex]8 \times - \frac{3}{2} = - 12[/tex]
Substitute new equation and add it to the top equation
[tex]3x + 2y = - 7[/tex]
[tex] - 3x + 7.5y = - 12[/tex]
[tex]9.5y = - 19[/tex]
[tex]y = - 2[/tex]
Now plug -2 for y into any equation and solve for x.
[tex]3x + 2( - 2) = - 7[/tex]
[tex]3x - 4 = - 7[/tex]
[tex]3x = - 3[/tex]
[tex]x = - 1[/tex]

∠A and ∠B are vertical angles. If m∠A=(5x+5)∘and m∠B=(4x+29)∘, then find the measure of ∠A.
Answer:
∠A = 175∘
Step-by-step explanation:
∠A = ∠B
5x-5= 4x+29
x = 34
∠A= 34*5+5
∠A=170+5=175
5x+5= 4x + 29
-5
5x=4x+24
-4x -4x
x=24
m∠A=5x+5
m∠A=5(24)+5
120+5
Answer=125
