An addition sentence, a multiplication sentence, and a division sentence are modeled on the number line.
the figure shows a number line. the numbers on the number line range from negative 15 to 15 in increments of 5. between every two numbers, four marks are made such that five divisions are formed between every two numbers. three rays are made one after the other towards left. the first ray starts from 0 and goes 4 divisions left, the second ray starts from the point where the first ends and goes 4 divisions left, and the third ray starts from the point where the second ray ends and goes 4 divisions left. all the three rays are labeled as negative 4.

what addition sentence is modeled?
what multiplication sentence is modeled?
what division sentence is modeled?

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

answer: it is d

step-by-step explanation:

the 3rd on is correct

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
