because obviously the pyramid has a square base and triangles around it, which rules out c, and if you try and fold them together in your head
Answer:
C
Step-by-step explanation:
the factor of x in the equation is the slope, which is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
going from the left point to the right point x changes by +3 units, and y changes by -1 unit.
so, the slope (and factor of x in the equation) is -1/3.
and the constant term in the equation is the y (axis) intercept of the line.
this is the y value, when x = 0 (intercepting the y axis).
and we see in the graph, when x = 0, the line goes through y = 2.
so, the equation has to be
y = -1/3 × x + 2
therefore, C is the right answer.
Answer:
I believe it will be greater than
Step-by-step explanation:
6/8 x 9 is 6.75, and 6/8 as a decimal is 0.75, so since 6.75 is greater, 6/8 x 9 will be greater.
Anyone, correct me if I am incorrect.
Answer:
He needs at least 77 on the 5th test.
<em>T₅ ≥ 77</em>
Step-by-step explanation:
If five numbers are to average 84, then their sum must be (5 x 84) = 420 .
Gale needs his five grades to add up to 420.
So far, he has (80 + 95 + 78 + 90) = 343 .
He needs at least (420 - 343) = <em>77 more</em> points on the 5th test.
