Which function rule defines f(x)?

Answers

Answer:

B. f(x) = -2x - 5

Step-by-step explanation:

✔️Find the rate of change:

Rate of change using two of the given pair, say (0, -5) and (1, -7)

Rate of change (m) = ∆f(x) / ∆x = (-7 -(-5)) / (1 - 0) = -2/1 = -2

✔️Find y-intercept (b):

y-intercept (b) = -5 because the y-intercept is the value of f(x) when x = 0.

✔️Substitute m = -2 and b = -5 into f(x) = mx + b

Thus,

f(x) = -2x + (-5)

f(x) = -2x - 5

I need help on both of these plss

Answers

Answer:

1. When combining 5+2+3 it equals 10; and when solving 5+(2+3) you solve what's in the parenthesis first. So the new problem is 5+(5), which equals 10.

2. Same goes for the second one, 11-2 is 9, then you just add the a because both have the same variable

hope that helped :) have an amazing day

Answer:

for 1: yes they are the same

for 2: true

Step-by-step explanation:

for 1: 5+2+3=10 and 5 +(2+3) = 10 because 2+3=5 so 5+5=10 therefore they are the same

For:2 9=11-2 because 11-2=9

calculate the area of this triangle 18cm, 14cm and height is 11cm​

Answers

Answer : 99cm^2

Hope this helps

The area of the triangle with a height of 11 cm and a base of 18 cm is,

99 cm².

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points.

Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We also know,

The way of classifying a triangle,

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

The area of a triangle is half times the product of the height and base.

The given triangle has a height of 11 cm and a base of 18 cm.

Therefore, The area of the triangle is,

= (1/2)×18×11 cm².

= 99 cm².

Kate had $140. She spent
2/5 of it. What amount did she spend?

Answers

2/5*140
= 56
So Kate spent $56

The amount Kate spent $ 56 of the $ 140 she had.

To find out how much Kate spent, we need to calculate 2 / 5 of the total amount she had, which was $ 140.By multiplying fractions we mean the product of a fraction with another number or a fraction. The product of such multiplication could be a fraction or a whole.

To do this, we can multiply $ 140 by the fraction 2 / 5:

= $ 140 * 2 / 5

= $280 / 5

= $ 56

Therefore, Kate spent $ 56 of the $ 140 she had.
