Solve for x using factorizing:
x^2 + 10 x - 24 = 0

The left hand side factors into a product with two terms:
(x - 2) (x + 12) = 0

Split into two equations:
x - 2 = 0 or x + 12 = 0

Add 2 to both sides:
x = 2 or x + 12 = 0
Subtract 12 from both sides:
Answer:  x = 2 or x = -12

Determine the slope and y-intercept of the graph:<br> 2x + 5y = 10
FinnZ [79.3K]

Slope is -2/5 and y-intercept is 2

Step-by-step explanation:

  • Step 1: Write the equation in slope-intercept form y = mx + b

2x + 5y = 10

5y = -2x + 10

y = -2/5 x + 10/5

y = -2/5 x + 2

  • Step 2: Find the slope and y-intercept from the equation.

Slope, m = -2/5

y-intercept, b = 2

Select all of the given trigonometric equations that are true statements. sin(180°) = cos(0°) cos(74°) = sin(16°) sin(20°) = cos
lara [203]

Answer:

Cos 74°= Sin 16°

Sin 20°= Cos 70°

Sin A°=Cos (90°- A°)

Step-by-step explanation:

This is because the three pairs are complementary i.e they add up to 90° and in trigonometric ratios, complementary ratios are equal.

survey was administered to students of other schools on a Saturday.

  • The type of error is the <u>selection bias error</u>.

Reasons:

The type of error made is a non sampling error, given that the target of the

study is the number of times in a week students at his middle school

attend the beach during the summer.

The errors are; Selection bias error.

  • The given that the students survey are not from his middle school.
  • The survey was carried out once on a Saturday, where the target was during the summer.

The selection bias error is a type error that is due to the researcher

chooses what to study, such that the participant have common

characteristics rather than being random.
