Answer:
X-4, Y-5
Step-by-step explanation:
If you look at the shape, you can see that 4 is about the size of x so therefore x is 4. Y standed up straight would be about 1 tic taller than x so therefore y is 5. MARK AS BRAINLIEST PLZ!
Answer:
<11,33>
Step-by-step explanation:
If it is perpendicular to <3,-1> We can use <0,0> as the other point to get the slope
m = (y2-y1)/(x2-x2)
The slope of the vector is
(-1-0)/(3-0)
= -1/3
Then we want a vector perpendicular, so we take the negative reciprocal of the slope
- (-3/1) =3
So the perpendicular slope is 3
Our new vector y/x = 3/1
Using cross products
3x=y
The magnitude has to be 11 sqrt (10)
magnitude = sqrt( ((x)^2 + y^2) = 11sqrt(10)
magnitude = sqrt( ((x^2 + y^2) = 11sqrt(10)
Square both sides
x^2+y^2 = 11^2*10
x^2 + y^2 =1210
We have 2 equations and 2 unknowns
x^2 +y^2 =1210 and
3x=y
Replace y with 3x
x^2 + (3x)^2 =1210
x^2 +9x^2 =1210
10x^2 =1210
Divide both sides by 10
x^2 =121
Take the square root of each side
sqrt(x^2) = sqrt(121)
x=±11
But it problems states it has to be in the first quadrant so x=11
x =11
Now we can find y
y =3x
y =11*3
y =33
The vector is <11, 33>

Complete Question
A contestant in a game show has 9,000 points. The contestant answers the next question incorrectly and loses 750 points. Does the word "lose" suggest a positive integer or a negative integer? What integer represents a loss of 750 points?
a) Positive, + 750
b) Positive , - 750
c) Negative , +750
d) Negative , - 750
Answer:
d) Negative , - 750
Step-by-step explanation:
We are told in the question that the contestant has 9000 points
Then he loses 750 points.
This means that the 750 points would be deducted from the 9000 points he the contestant has already.
The word lose is a negative and it carries the Subtraction (-) sign,
hence, lose suggests a negative integer which is given as:
-750
Option d is the correct option
