What is the y-intercept of this quadratic function?<br> f(x)=-x2+10x-22

IrinaK [193]

Answer:

The y intercept is (0,-22)

Step-by-step explanation:

To find the y intercept, set x =0 and solve for y

f(0)=-0^2+10*0-22

= -22

Answer:

C) $3c-5d$

Step-by-step explanation:

$-c+5d+7c-11d+d-3c$

Group the similar terms together:

$-c+7c-3c+5d-11d+d$

Add/subtract the "c" variables:

$3c+5d-11d+d$

Add/subtract the "d" variables:

$3c-5d$

The graph of y^2=x^2 is symmetric with respect to which axis? a. x-axis c. both b. y-axis d. neither

PtichkaEL [24]

Answer:

c. both

Step-by-step explanation:

Given equation is $y^2=x^2$

Now we need to check if the graph of $y^2=x^2$ is symmetric with respect to which axis?

a. x-axis c. both b. y-axis d. neither

We know that if f(-x) reflect the graph about y-axis

so let's change x by -x into given function to see if that equation remains unchanged or not

$y^2=(-x)^2$

$y^2=x^2$

That is same as previous equation.

<u>Hence given graph is symmetric about y-axis.</u>

We know that if -f(x) reflect the graph about x-axis

so let's change y by -y into given function to see if that equation remains unchanged or not

$(-y)^2=x^2$

$y^2=x^2$

That is same as previous equation.

<u>Hence given graph is symmetric about x-axis.</u>

So the correct choice is c. both

Jim is showing his work in simplifying (−8.5 + 6.1) − 1.3.

dexar [7]

9514 1404 393

Answer:

In step 4, Jim's answer is incorrect.

Step-by-step explanation:

In step 1, Jim swaps the order of addends using the commutative property of addition.

In step 2, Jim uses the distributive property to factor -1 from the final two terms. (The associative property lets Jim move parentheses.)

6.1 +(-8.5 -1.3) . . . associative property

6.1 +(-1)(8.5 +1.3) . . . distributive property

In step 3, Jim has used the properties of real numbers to form the sum of two of them.

In step 4, Jim wrote an answer of 1.1, when the answer should have been -3.7. Jim's answer is incorrect.

The descriptive statements about steps 2 and 4 are both true.

What is the next number in this series: 1 2 8 48 364

evablogger [386]

Did you mean to put 384? because if you did then the next number would be 3840. It would because 1*2=2. 2*4=8. 8*6=48. 48*8=384. 384*10=3840. Hope this helped.
