Answer:
a. square pyramid b. sphere d.triangular pyramid
2 1/2 bags of potatoes would weigh 14 3/8 pounds
Find the scale factor then multiply 3 by scale factor to find m. Scale factor is found by dividing larger side by smaller side. In this example, divide 10 by 6. (10 / 6 = 1.66666...) This means the larger triangle is 1.6x bigger than the smaller one. Then multiply 3 by 1.6666.. to find m. Hope this helps! :)
Btw your answer would be m = 5 but I didn’t want to give that away right away.
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
+ = 1 ( multiply through by 2 to clear the fractions )
x + y = 2 ( subtract x from both sides )
y = - x + 2 ← in slope- intercept form
(a) with slope m = - 1
(b) with y- intercept c = 2
(c)
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation of PQ
To find c substitute (2, - 8) into the partial equation
- 8 = - 2 + c ⇒ c = - 8 + 2 = - 6
y = - x - 6 ← equation of PQ
To show (- 1, - 5) lies on PQ, substitute x = - 1 into the equation and evaluate for y.
y = - (- 1) - 6 = 1 - 6 = - 5 ← the given y- coordinate
Thus PQ passes through (- 1, - 5 )
6/3 = 2
3 x 2 = 6
3(2) = 6
x = 2
