Can someone help me and tell me the steps plzz

Answer:

Step-by-step explanation:

f(x) = 7x² - 15x + 2

A) f(1) = 7*1² - 15*1 +2 = - 6

f(1.5) = 7*(1.5)² -15*1.5 + 2 = - 4.75

B) f(2.2) = 7*(2.2)²-15*(2.2)+2 = 2.28

C) f(1) = 7*1² - 15*1 +2 = - 6

f(1) = 7*2² - 15*2 +2 = 0

D) not for all real numbers because we already have

f(2.2) = 7*(2.2)²-15*(2.2)+2 = 2.28 that is positive.

This is factoring quadratics with a leading coefficient: 5p to the 2 power - 52p + 20

Mashutka [201]

Answer:

(-5p + 2)(-p + 10)

Step-by-step explanation:

$5p^{2}$ -52p + 20

(-5p + 2)(-p + 10)

You can double check this by using the distributive property..

-5p * -p = -5p^2

2*-p = -2p

10*-5p = -50p

10*2 = 20

-5p^2 + -2p + -50p + 20

Now we combine like terms and simplify

-5p^2 -52p + 20

So, we are correct

What is the simplified value of this expression pls help

tester [92]

Answer:

Step-by-step explanation:

Remove parentheses.

$\frac{-8+4(4.5)}{6.25-8.25} \\$

Add −8 and 4.5.

$\frac{4(-3.5)}{6.25 - 8.25} \\\\$

Subtract 8.25 from 6.25.

$\frac{4*-3.5}{-2}$

Multiply 4 by −3.5.

$\frac{-14}{-2}$

Divide −14 by −2.

= 7

1.) What is the best approximation of the solution to the system to the nearest integer values?

melisa1 [442]

Part 1) we have

$5x+2y=16$ ------> equation A

$x+3y=12$

$x=12-3y$ ------> equation B

Substitute the equation B in equation A

$5[12-3y]+2y=16$

$60-15y+2y=16$

$13y=44$

$y=44/13=3.38$

Find the value of x

$x=12-3(44/13)=1.85$

the best approximation is the point $(2.3)$

therefore

the answer Part 1) is the option C

$(2.3)$

Part 2) we have

$y=-x-2$ ------> equation A

$y=3x+2$ ------> equation B

equate equation A and equation B

$-x-2=3x+2$

$4x=-4$

$x=-1$

Find the value of y

$y=-(-1)-2=-1$

the solution is the point $(-1,-1)$

therefore

the answer Part 2) is

$(-1,-1)$
