Complete the equation of the line through (3,-1) and (4,7)
Answers
gradient, m = y2 - y1 / x2 - x1
m = 7 - (-1) / 4 - 3
m = 8
a straight line is y=mx+c
thus, we have to find the c which is y-int by subs one of the coordinate to the equation.
y=mx + c
7=8(4) + c
c = -25
thus the equation is y = 8x - 25
The answer would be Y=8x-25

The lengths of the two legs of a right triangle are 4 and 7. What is the length of the
hypotenuse? Express answer in Simplified Radical Form.
Answers
Answer:8.06
Step-by-step explanation:
4 x 4= 16 7 x 7 = 49
49+16=65
square root of 65 =8.06
Answer:
[tex] \sqrt{65} [/tex]
Step-by-step explanation:
To find the hypotenuese of a right angle you use the pythagreon theroem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.
[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]
The radical form answer is above, otherwise it would be a decimal.

The product of a number and -5 is 35.
Write the sentence as a equation
Answers
Answer:
-5x=35
Step-by-step explanation:
The product= an answer to a multiplication problem, so product means multiply
A number= a variable, an unknown integer(number)
So, therefore, a number multiplied by -5 = -5x
x= the variable, the variable being multiplied should go right after the known number.
so, -5x=35
solved= divide -5 by 35 which equals -7
a negative number and a positive number being multiplied make the product a negative number.
