Answer:

(0,-2); The y-intercept is y=-2.

Step-by-step explanation:

Recall that the y-intercept is simply (0, y). In other words, we simply need to plug zero into the equation to acquire the y.

Thus:

y=4x^2-7x-2

y=4(0)^2-7(0)-2

y=-2

Answer:

720

Step-by-step explanation:

because 8% of 9000$ is 720$.

another way.

Step 1: Our output value is 9000.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$9000=100$.

Step 4: Similarly, $x=.8%$.

Step 5: This results in a pair of simple equations:

$9000=100%(1)$.

$x=.8%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

Step 7: Again, the reciprocal of both sides gives

Therefore, 8%of $9000$ is $720

Please help with this math problem! The intersection of GK and HL is point P. Which triangle must be an isosceles triangle? *loo
Whitepunk [10]

None of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.

<h3>Properties of an Isosceles Triangle</h3>
  • An isosceles triangle has two base angles having equal angle measure.
  • The side lengths that are opposite each of the equal base angles are also congruent to each other.

Thus, none of the triangles listed has two equal base angles or two equal side lengths, therefore: D. No triangle is isosceles.
