Answer:
The equation is y = 2x + 11.
Step-by-step explanation:
It is given that the gradient of the equation is 2. Using slope-form formula, y = mx+b where m is gradient and b is y-intercept. In order to find b, you have to substitute x-coordinate and y-coordinate into the equation :
y = mx + b
m = 2
At(-4,3),
3 = 2(-4) + b
b = 3 - 2(-4)
= 11
Part 1)
we know that
the property of cyclic quadrilaterals for which opposite angles are supplementary
then
m∠A°+43°=180°------------> m∠A=180°-43°=137°
the answer is m∠A=137°
Part 2) <span>Quadrilateral ABCD is inscribed in a circle. What is the measure of angle A?
we know that
</span>the property of cyclic quadrilaterals<span> for which opposite angles are supplementary
then:</span>
<span>m∠A+m∠C=<span>180<span>∘
(2x+9)+(3x+1)=180---------------> 5x+10=180
x=(180-10)/5=34
</span></span></span>m∠A=2x+9-------------> 2*34+9=77°
<span>
the answer is </span>m∠A=77°<span>

Answer:
12x^2+ 4y^2-26xy
Step-by-step explanation:
2x times 6x= 12x^2
2x times -y=-2xy
-4y times 6x= -24xy
-4y times -y= 4y^2
12x^2- 2xy- 24xy +4y^2
12x^2+ 4y^2-26xy
I hope this is right, sorry if its not
Solving a quadratic formula depends on the question asked. For example, if you are given a quadratic equation and then you are asked to find the roots of the equation, then you can solve it by remainder theorem or long method. So long as your quadratic equation is given and you are asked this tyoe, you can answer any problem.
