Answer:

Step-by-step explanation:

Always start by finding the slope when you're given two points! (This means that we can rule out C and D.) The equation for slope is

$m = \frac{y2 - y1}{x2-x1}$

You can remember this by thinking about it being rise over run, or the distance you go up or down divided by the distance you go across. This means that answer choices B and D are incorrect.

Next, what do we plug into slope-intercept form to get the y-intercept? The slope, and one other point.

y = mx+b

You can see that if we were to plug in m, x, and y, we'd only have b left, and we could solve!

This means that choice A is correct.

Question 7 of 10

Mama L [17]

Answer:

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the discriminant is

Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real irrational roots

• If b² - 4ac > 0 and a perfect square then 2 real rational roots

• If b² - 4ac = 0 then 1 real double root

• If b² - 4ac < 0 then 2 complex roots

Given

x² + 3x - 7 = 0 ← in standard form

with a = 1, b = 3, c = - 7 , then

b² - 4ac

= 3² - (4 × 1 × - 7) = 9 + 28 = 37

Since b² - 4ac > 0 then 2 real irrational roots

PLEASE HELP!!! WILL AWARD BRAINLIEST!!

Tcecarenko [31]

Answer:

The value of f(1) is larger than the value of f(3)

Step-by-step explanation:

Put the numbers in the equation and do the arithmetic.

f(1) = -2(1²) +3(1) +10 = 11

f(3) = -2(3²) +3(3) +10 = 1

11 is larger than 1, so f(1) is larger than f(3).

A bank loaned out $28,500, part of it at the rate of 14% annual interest, and the rest at 4% annual

Flauer [41]

Answer:

$15,000 was invested at 14% per year, and $13,500 was invested at 4% per year.

Step-by-step explanation:

Given that a bank loaned out $ 28,500, part of it at the rate of 14% annual interest, and the rest at 4% annual interest, and the total interest earned for both loans was $ 2,640.00, to determine how much was loaned at each rate you must perform the following calculations:

28,500 x 0.14 + 0 x 0.04 = 3,990

20,000 x 0.14 + 8,500 x 0.04 = 3,140

15,000 x 0.14 + 13,500 x 0.04 = 2,640

Therefore, $ 15,000 was invested at 14% per year, and $ 13,500 was invested at 4% per year.
