Answer:

Step-by-step explanation:

The y-intercept is the point where the graph cuts the y axis - that is when x = 0.

f(x)=138⋅1.9x

ehen x = 0 f(x) = 0 so the y-intercept is at (0, 0).

Part 1: Create your own quadratic equation that cannot be solved by factoring, but can be solved using the quadratic formula. Id

eimsori [14]

when you use all prime, non-one numbers for b and c, it cannot be factored most of the time

example
1x^2+7x+5
a=1
b=7
c=5
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
x= $\frac{-7+/- \sqrt{7^2-4(1)(5)} }{2(1)}$
x= $\frac{-7+/- \sqrt{49-20} }{2}$
x= $\frac{-7+/- \sqrt{29} }{2}$
x= $\frac{-7+ \sqrt{29} }{2}$ or $\frac{-7- \sqrt{29} }{2}$

The time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H, applied to the pot

Lera25 [3.4K]

Answer:

T = 96

Step-by-step explanation:

From the question given above, we were told that the time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H. This can be written as:

T ∝ 1/H

T = K/H

Cross multiply

K = TH

Next, we shall determine the value of K. This can be obtained as follow:

H = 8

T = 120

K =?

K = TH

K = 120 × 8

K = 960

Finally, we shall determine the value of T when H = 10. This can be obtained as illustrated below:

H = 10

K = 960

T =.?

T = K/H

T = 960/10

T = 96

3. At a bargain store, Jamal bought 2 items that each cost the same amount. Isaiah bought 3 items that each cost the same amount

coldgirl [10]

Answer:

$6.75 and $4.50

Step-by-step explanation:

a) Jamal spent:

Isaiah spent:

3 (x - 2.25)

The equation is:

2x = 3(x - 2.25)

b) Solving the equation

2x = 3x - 6.75
3x - 2x = 6.75
x = 6.75

c) Jamal's items cost

$6.75 each

Isaiah's items cost

$6.75 - $2.25 = $4.50 each
