Answer:
0.98
Step-by-step explanation:
98% = 0.98 in decimal form. Percent means 'per 100'. So, 98% means 98 per 100 or simply 98/100. If you divide 98 by 100, you'll get 0.98 (a decimal number).
Answer:
A. Span (w, y) = Span (w, x, y)
C. Span (w, x) = Span (w, x, z)
D. Span (w, x) = Span (w, z)
Step-by-step explanation:
The vectors x, y , z are non zero vectors. Vector has direction and magnitude both. For the given equation of -2x - 4y + 3z the span for w, y equals the span of w,x,y. The statements A, C and D are true and the other statements B and E are not correct. For the given equation the vector span y,z does not equals span of x,y,z.
Answer:
Choice B: Only (-1,-5)
Step-by-step explanation:
With this one, first the equation needs to be reduced into point-slope format.
y+5=2(x+1)
Distributive Prop.
y+5=2x+2
Carry over the 5 to the opposite side.
y=2x-3
Now, with the point slope form, it makes it easier to plug in the question choices to find which if any are correct.
Choice A: X is 5; Y is 10
y=2x-3
y=2(5)-3
y=10-3
y=7
This does not give a y value of 10, so it is false.
Choice B: X is -1; Y is -5
y=2(x)-3
y=2(-1)-3
y= -2-3
y= -5
This does give a y value of -5, so it is true. Choices C and D are therefore false as well, since only Choice B works.
