1 answer:

7 0

$-5 \dfrac{1}{4} - (-7 \dfrac{1}{2} ) = -5 \dfrac{1}{4} + 7 \dfrac{1}{2} =-5 \dfrac{1}{4} + 7 \dfrac{2}{4} = 7 \dfrac{2}{4} -5 \dfrac{1}{4} =2 \dfrac{1}{4}$

Let's find out the gradient (Slope " m ") of line q ;

$\qquad \sf \dashrightarrow \:m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$\qquad \sf \dashrightarrow \:m = \dfrac{4 - 0}{0 - 1}$

$\qquad \sf \dashrightarrow \:m = - 4$

Now, since we already know the gradient let's find of the equation of line by using its Slope and one of the points using point slope form of line :

$\qquad \sf \dashrightarrow \:y - 4 = m(x - 0)$

$\qquad \sf \dashrightarrow \:y = mx + 4$

Now, plug in the value of gradient ~

$\qquad \sf \dashrightarrow \:y = - 4x + 4$

here we can clearly observe that, the Area under the curve can easily be represented as :

$\qquad \sf \dashrightarrow \:y < - 4x + 4$

Since, all the values of y that lies in the shaded region is smaller than the actual value of y for the corresponding values of x in the equation of line q

Jerry had 1 gallon of ice cream he used 3/10 gallon to make chocolate milkshakes and 0.40 gallon to make vanilla milkshakes how

Gre4nikov [31]

Let
x------> the <span>remaining ice cream

we know that
3/10------> 0.30
so

x=1-0.30-0.40-----> x=1-0.70------> x=0.30 gal------> 3/10 gal

the answer is
3/10 gal</span>

when determining whether proportion are Equal we need to do which of the following? .addition, .multiply straight across, dividi

Lisa [10]

Answer:

Cross Multiplying.

Step-by-step explanation:

By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by 15 and 5 by 15 to get 45:75.
