First, solve for x.

3x-7+2x+17=90

5x+10=90

5x=80

x=16

Then put 16 in for x.

2(16)+17=

What is the answer to this?

konstantin123 [22]

Answer:

$\huge\boxed{-6}$

Step-by-step explanation:

Since we know the values of a, b, and c, we can substitute them into our expression and get the value.

$-2b + | -3c + a |\\\\-2(6) + |-3(-3) + -3 |$

A negative multiplied by a negative gets us a positive.

$-2(6) + |9 + -3 |$

Adding a negative is the same as subtracting a positive.

$-2(6) + |9 -3 |\\-2(6) + 6$

$-2 \cdot 6 = -12\\\\-12+6\\\\-6$

Hope this helped!

Kaya is saving money at a rate of $30 per month. Edgardo is saving money at a rate of $35 per month. They both started saving at

ladessa [460]

Let Kaya's savings be 30x and Edgardo's savings be 35x If they both started saving at the same time: f(x)=30x f(x)=35x Now, sub in values for x in to the function starting with 0. Subtract y2-y1 and x2-x1 for both functions. For slope: m=y2-y1/x2-x1 so your result will be m=30/1=30 for f(x) = 30x and m=35/1=35 for f(x) = 35x so the slopes are m=30 and m=35 respectively!
