A square root of any number greater than 0 always has two answers, one positive and one negative.
Squareroot (36) = 6 or -6.
Since 6×6=36 and -6×-6=36.
Squareroot (0)= just 0 because there is no negative 0 (:
<span>the answer is subtraction</span>
2 and 2/4 = 10/4
10/4 ÷ 1/4 = 10/4 × 4/1 = 10 cups
Answer:
y = -5/8x - 11/4
Step-by-step explanation:
Since we already know the slope which is -5/8. This will be the m in the equation.
To find the y-intercept, plug the coordinates into the equation, which is
y= -5/8 + b
6 = -5/8(-14) + b
6 = 35/4 + b
= -11/4 = b
Expression 2a + b represents the situation (total cost) of buying a apples and b bananas.
<u>
Solution:
</u>
Given that Daryl is buying apples and bananas.
He bought (a) pounds of apples that cost \$2 per pound.
He bought (b) pounds of bananas that cost \$1 per pound.
Need to write an expression which represents the situation.
Cost of 1 pound of apple = 2
\text { So cost of } a \text { pounds of apple }=a \mathrm{x} \text { Cost of } 1 \text { pound of apple }=a \mathrm{x} 2=2 a
Cost of 1 pound of banana =1
\text { So cost of } b \text { pounds of banana }=b \text { x Cost of } 1 \text { pound of banana }=b \times 1=b
Total cost of apples and banana = 2a + b
Hence, the required expression is 2a + b.
