If y=3x+4 we're changed to y=5x+4 how would the graph of the new function compare to the first one
dusya [7]

Answer:

A. It would be steeper

Step-by-step explanation:

In the linear equation y = mx + b, m is the slope and b is the y intercept.

In this problem, the function is changed to have a larger slope of 5, compared to the original slope of 3. But, the y intercept stays the same.

Since the y intercept remained the same, it will not be shifted in any direction.

But, with a larger slope, the graph will be steeper.

So, the correct answer is A. It would be steeper

A private shipping company will accept a box for domestic shipment only if the sum of its length and girth​ (distance around) do
aivan3 [116]

Answer:

18×18×36

Step-by-step explanation:

According to the Question

108≥ 4h + w

Volume V is given by

V = wh^2

⇒V= (108-4h)h^2

⇒V= 108h^2 - 4h^3

Now differentiating and keeping = 0 we get

V' = 216h - 12h^2 = 0

h = 216/12 = 18

w = 108 - 4×18 = 36

V = 36×18^2 = 11664 from a box of 18×18×36.

Two Supplementary angles are in the ratio 5 : 7, then the measure of two angles are *
inn [45]

Answer:

75°, 105°

Step-by-step explanation:

Supplementary angles sum to 180°

Sum the parts of the ratio, 5 + 7 = 12 parts

Divide 180° by 12 to find the value of one part of the ratio.

180° ÷ 12 = 15° ← value of 1 part of the ratio, thus

5 parts = 5 × 15° = 75°

7 parts = 7 × 15° = 105°
