Answer:
x = -12
Step-by-step explanation:
-1/4x - 12 = x + 3
-x - 48 = 4x + 12
-x -4x = 12 + 48
-5x = 60
x = -12
Answer:
Step-by-step explanation:
you could think that 22% is close to 25% , so one forth of it, 1/4
78 percent is close to 80
1/4 of 80 is 20
actually 78*22/100=17.16
√(10) = 3.16 but it asks you to approximate to the nearest integer.
3.16 to the nearest integer = 3
Your answer should be 3
<h3>
Answer: -76 (choice C)</h3>
Explanation:
We're applying the dot product.
u dot v = 3*(-4) + (-8)*8
u dot v = -12 - 64
u dot v = -76
The idea is that we multiply the x coordinates together, and the y coordinates together separately. Afterward you add the products. The result of any dot product is a scalar value, aka a single number.
The dot product is useful in many applications. One of which is to determine if two vectors are orthogonal.
Based on the equation that shows the relationship between homework and weekly quiz scores, the number 63 would represent the weekly quiz score if no hours were spent on homework.
<h3>What is the meaning of the y-intercept?</h3>
The slope y=63+6.7x, takes the form of the linear equation which is:
y = mx + c
Where m is the slope
c is the y-intercept
The y-intercept is the value of y when the value of x is 0.
x in this case is the number of hours spent doing homework.
If the student doesn't spend any hours doing homework then their weekly quiz score will be the value of 63.
