Answer for question 1: Last table.

Step-by-step explanation: The answer is not the top 2 because the y-intercept is plus 5 not minus 5. Let us now look at the bottom two and calculate if the slope is equal to -2. (Second to last table) 13-9/4-2= 4/2=2. This does not equal -2. Let us look at the last one. 13-17/4-2= -4/2= -2. The last one is the correct answer because it has the y-intercept of 5 and the slope of -2.

Answer for question 2: 4

Explanation: The rate of change formula is y1-y2/x1-x2. Let us take 16-8/1-1/2. This is equal to 4 because 16-8 is 8 and 1-1/2 is 1/2. 8 divided by 1/2 is 4.

If x = -3 is a zero of f(x), which of the following must be true?
Alla [95]

Answer: B

Step-by-step explanation: You make the values in the parentheses equal to zero.

(X + 3) = 0

X = -3

A is wrong because the root would be 3, not negative 3. C is wrong because 3 isn’t guaranteed to be a root. D is wrong because -3 is a real solution.

Xelga [282]

Answer:

17.5

Step-by-step explanation:

The following data were obtained from the question:

Angle R = 105°

Side R = r

Side S = 15

Side T = 6

The value of r can be obtained by using cosine rule formula as shown below:

inding sides:

r² = s²+ t² – 2st cos(R)

r² = 15² + 6² – 2 × 15 × 6 × cos105°

r² = 225 + 36 – 180 × cos105°

r² = 261 + 46.587

r² = 307.587

Take the square root of both side

r = √307.587

r = 17.5

Therefore, the value of r is 17.5

one half of a number is added to 9, giving thr result of at least 4. Find the unknown numbers in the description.
natta225 [31]
Hey there!

We'll call this number <em>x.</em> Using some keywords and prior knowledge, we can translate this English into math.

Our keyword is of. When we say of, it means multiply. Why?

For example, if we wanted 1/2 of 4, we would compute:

1/2 * 4 = 4/2 = 2

And in your head, if we wanted two equal groups of 4, there'd be 2 in each. We say two equal groups because multiplying by 1/2 is the same as dividing by 2.

Therefore, we have 1/2 of a number, giving us:

\frac{1}{2}x

Next, we know we're adding this result to 9.

\frac{1}{2} x + 9

Here's where it can get a bit tricky. We want this value (above) at least four. That means that the value can be equal to four, but it could also be greater. That means our sign is greater than or equal to:

\frac{1}{2} x + 9 \geq 4

We can then subtract 9 from both sides:

\frac{1}{2} x \geq -5

Multiply both sides by 2:

x \geq -10

Therefore, x can be -10 or more. Some examples are -10, -9, -8, and so on.

If we try -8:

\frac{1}{2}(-8)+9 \geq 4

-4+9 \geq 4

5  \geq  4

Therefore, we're correct.

Hope this helps!
