How do I solve 2(x+1) + 5(2x-3)=

Mathematics

You multiply 2(x+1) which is 2x+2.

Then you multiply 5(2x-3) which is 10x-15

Finally, you add 2x+2 and 10x-15, and you get 12x-13


The answer is 12x - 13


Hope this helps!

Use the distributive property: multiply the number outside of the parentheses by BOTH numbers inside. 2 × x and 2×1 so first part is 2x+2 second part: 5 × 2x and 5×-3 is 10x-15 so 2x+2+5x-15= 7x-13

Point P has coordinates (2 , 3) point Q is symmetric to point P with respect to the line x=4 what are the coordinates of point Q
Ierofanga [76]

Answer:

Q is (6, 3).

Step-by-step explanation:

The line x = 4 is a vertical line on the coordinate grid which passes through the  x-axis at the point where  x = 4.

So the x coordinate of Q will be the same distance after  x = 4 as P is before it. That is where x = 4+2 = 6. The y coordinate will be the same as that of P.

(Imagine that  the line x = 4 is a mirror, then Q is the image of P).

PLS HELP ILL GIVE BRAINLIEST!
Vlad1618 [11]

Answer:

g(-4) = 8

Step-by-step explanation:

If x = -4, we would use the expression of the limit "if x is less than or equal to -1" since x is just that.

We would then plug in our x value into the expression and solve for g(x)

g(x) = -x + 4 -->  -(-4) + 4 = 4 + 4 = 8

How to multiply a whole number by a fraction like 4/6 x 4 etc .​
jeka57 [31]

Answer:

See below, please!

Step-by-step explanation:

To multiply a whole number by a fraction, set up both numbers so that they have a numerator and denominator, multiply the corresponding parts, and simplify.

Ex: \frac{4}{6}*\frac{4}{1}. Both of them are in fraction form, right? Now multiply the numerator and denominator together. Doing this, you get 16/6. Now simplify. Look for a common factor between both the numerator and denominator. We can see that one common factor is 2. So, our simplified fraction is 8/3.

Hope this helped!
