Mathematics

NISA [10]3 years ago

Answer:

f(1)=13

f(-9)=88

f(0)=0

f(-15)=20

The above mentioned are false statements

Step-by-step explanation:

f(1)=13 : false because "13" is out of range -40≤f(x)≤-10

f(-9)=88 : false because "88" is out of range -40≤f(x)≤-10

f(0)=0 : false because "0" is out of range -40≤f(x)≤-10

f(-15)=-20 : false because "-15" is out of domain -10≤x≤20

If the domain is -10\leq x \leq 20, it means that you can only accept inputs between -10 and 20.

In other words, you can write f(x) only is x is between -10 and 20.

This rules out the option f(-15)=-20, because you can't accept -15 as input, because it's less than -10.

Similarly, if the range is -40\leq f(x) \leq -10, it means that the function can only output numbers between -40 and -10.

In other words, you can write f(x)=k only is k is between -40 and -10.

This rules out the first two options, because their output is positive, and also f(0)=0

Find the x and y intercepts 5y + 3x = 15
Tomtit [17]
First, find the x-intercept.

The x-intercept will be at the point (x, 0) where x is any real number. If we substitute the x-coordinate and the y-coordinate for the x and y variables in the equation, we can solve for x.

5y + 3x = 15
5(0) + 3x = 15
3x + 15
x = 5

We found the x-intercept now find the y-intercept with the same process.

The y-intercept will be at the point (0, y) where y is any real number.

5y + 3x = 15
5y + 3(0) = 15
5y = 15
y = 3

So, the x-intercept is (5, 0) and the y-intercept is (0, 3)

Hi please help i’ll give brain
NARA [144]

Answer:

The GCF is going to be 20

Step-by-step explanation:

This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here

The prime factorization of 20, 2 × 2 × 5= 20

The prime factorization of 80, 2 × 2 × 2 × 2 × 5 = 80

The common factors are 2, 2, and 5. We multiply those to get the GCF.

2 × 2 × 5 = 20
