Answer:
(x, y) = (3, 5/2)
Step-by-step explanation:
I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.
Now just add those from top to bottom.
Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.
(x, y) = (3, 5/2)
Answer:D
Step-by-step explanation:
We can set up an equation for 2/7 = x/3395
We can then solve for x by isolating it. We will multiply each side by 3395 to get x by itself
Our equation is now 3395× (2/7)=x
3395×(2/7)=970
So x=970

Answer:
Proved CA=CB
Step-by-step explanation:
Given,
In ΔABC, CP is perpendicular to AB.
And CP bisects AB.
So, AP=PB and ∠CPA=∠CPB=90°
The figure of the triangle is in the attachment.
Now, In ΔACP and ΔBCP.
AP = PB(given)
∠CPA = ∠CPB = 90°(perpendicular)
CP = CP(common)
So, By Side-Angle-Side congruence property;
ΔACP ≅ ΔBCP
According to the property of congruence;
"If two triangles are congruent to each other then their corresponding sides are also equal."
Therefore, CA = CB (corresponding side of congruent triangle)
CA = CB Hence Proved
The initial value is the y intercept. in this case, it is -5
