Answer:

x=1 x=-4

Step-by-step explanation:

Factorise the expression

(x-1)(x+4)

each bracket equals to 0 and as its a quadratic there will be 2 answers

so x-1=0 x+4=0

x=1 x=-4

16 question Write a rule for the linear function in the table

Ira Lisetskai [31]

To write the rule or equation of the linear function we need to find the slope of the function first. Using any two points we can find the slope.

Using the first two points (-3, -1) and (0, 2).

Slope (m) of the function would be:

$m= \frac{-1-2}{-3-0}= \frac{-3}{-3} =1$

Using slope and the point (0,2) we can write the equation of the line as:

y - 2 = 1(x-0)
y = x + 2

Thus, the correct rule for the given linear function is x+2

Jennifer bought 1/2 pound of ham for 3 sandwiches. If she puts the same amount of ham on each sandwich, how much ham will each s

Vesna [10]

=1/2 pound ham ÷ 3
=1/2 ÷ 3/1
to divide fractions, multiply by reciprocal/inverse of 3
=1/2 * 1/3
=1/6 pound per sandwich

ANSWER: Each of the 3 sandwiches can have 1/6 pound of ham

Explain how you know 21/100 is greater than 1/5

Nataly_w [17]

This problem can be solved using equivalent fractions. The first step in resolving this problem is to realize that fractions are best compared when they both have the same denominator. In this case, I will choose to make that common denominator 100. There is no need to rewrite the fraction $\frac{21}{100}$ as the denominator for this fraction is already 100. The fraction $\frac{1}{5} =\frac{20}{100}$ . This is achieved by multiplying both the numerator and denominator by 20. Now that the two fractions have the same denominator, we can easily see that $\frac{21}{100}$ is greater than $\frac{1}{5}$ because it is greater than its equivalent fraction.
