70/85 x 100 = 82.4 (3s.f.)
Answer:
RTA= (x-2)·(x-11/2)/(x-2)(x-4)= (you can simplify again if you want by eliminating both (x-2)
(x-11/2)/(x-4)
Step-by-step explanation:
Ok we need to simplify the expression so:
x^2+3x-10= Bhaskara formula=
-3(±√9-4·1·(-10))/2·1=
X1=(-3+7/2)--> X1=2(R)---> (X-R)--->X-2
X2=(-3-7)/2 --> X2=11/2(R)---> (X-R)--->X-11/2
x^2-6x+8= Bhaskara formula=
6(±√36-4·1·8)/2·1=
X1=(6-2)/2=2--> X1=2(R)---> (X-R)--->X-2
X2=(6+2)/2=2--> X2=4(R)---> (X-R)--->X-4
so, The simplify expression is
(x-2)·(x-11/2)/(x-2)(x-4)=
Eliminate parentheses using the distributive property.
4806x -3204 +2 = 1360 -544x +90x
5260x = 4562
x = 4562/5260
x = 2281/2630
Answer:
Step-by-step explanation:
Our line's equation is;
2y = -8x + 12
Dividing throughout by 2 we get;
y = -4x + 6
The slope of our line = -4
We are to choose a line whose slope is -4 (from those four options)
A slope of -4 means that for every positive 1 move along the x-axis, there is a negative 4 move along the y-axis.
The line that satisfies this condition is the third line.
