Answer:

-3/8+4x-9z

Step-by-step explanation:

"The sum of -3/8" means -3/8+ some number, which we find out (later in the expression) to be 4×x (that is 4 times x), or 4x. So we add on 4x to the expression, which becomes -3/8+4x. Then, it says "minus 9 times z", so we just take away 9×z. So, the final expression is -3/8+4x-9z.

Hope this helps! I got it right on Edgen.; you should trust me

An algebraic phrase or expression is a mixture of integer constants, variables and algebraic operations like addition, subtraction, multiplication, division and exponentiation. In this problem, you need to isolate first what is grouped together or what needs to be done first which in this sentence, "the sum of negative three-eighths and four. By substitution, it would be (-3/8+4). Then you multiply their sum by x so it would result to (-3/8+4)x. After that it is said that you need to minus that to nine times z which is 9z. This will result to an expression like this (-3/8 +4)x-9z. In the simplest term, the answer would be 9/8x-9z.

105 + 35m = expression . Apply the distributive property and the greatest common factor to write an equivalent
andrey2020 [161]

Answer:

<h2>35 × (3 + m)</h2>

Step-by-step explanation:

The distributive property:

<em>a × (b + c) = a × b + a × c</em>

105 = 35 × 3

35m = 35 × m

105 + 35m = 35 × 3 + 35 × m = 35 × (3 + m)

Write an equation in slope-intercept form for the line passing through the pair of points.
Umnica [9.8K]
First find your slope! by doing
y2-y1/x2-x1
in this case it would be
2-(-3)/-1-(-6)
It would give you 5/5 which would reduce to 1 meaning your slope equals 1
with your slope now you should use the point slope formula y-y1=m(x-x1)

i’m going to use the point (-1,2) so the equation would be

y-2=1(x-(-1))

simplifying that you would get

y-2=1x+1

then put it in y=mx+b form and get

y=x+3
