Choose the equation below that represents the line passing through the point (−2, −3) with a slope of −6.

Daniel [21]

Y=mx+b where m=-6, x=-2, and y=-3. Substituting these values in would result in -3=(-6)(-2)+b, which would simplify to -3=12+b, and further to b=-15. This would mean the y intercept is equal to -15, or (0,-15). To check, (-6)*(-2)-15 is in fact equal to -3, thus allowing easy identification of a graph, which will cross the y axis at -15 and decrease in y-value by 6 with every increase in x-value.

Tony’s Electronics is marking down the price of a TV 23% from the original price of $175. Which expression can be used to find t

Arlecino [84]

Answer:

The sale price is $\$134.75$

The expression is $\$175(0.77)$

Step-by-step explanation:

we know that

The sale price is equal to subtract the discount price from the original price

The discount price is equal to multiply the original price by the percent discount in decimal form

Let

x ----> the sale price

y ---> discount price

$23\%=23/100=0.23$ ----> percent discount in decimal form

$y=\$175(0.23)=\$40.25$

$x=\$175-y$

substitute

$x=\$175-\$40.25=\$134.75$

therefore

the expression is

$175-0.23(175)\\175(1-0.23)\\175(0.77)$

Jervane is planning on buying a coffee and several donuts for a road trip. She wants to spend no more than $20 in total. Coffee

max2010maxim [7]

Answer:

8

Step-by-step explanation:

Given:

Total money Jervane can spend = $20.

Cost of a coffee = $3.

Cost of a donut = $2.

To find: Maximum number of donuts Jervane can buy.

Solution:

Let the number of donuts she can buy be $x$ .

She wants to spend no more than $20 in total.

So,

$3+2x\leq 20$

$\Rightarrow 2x\leqslant 20-3$

$\Rightarrow 2x\leqslant 17$

$\Rightarrow x\leqslant \frac{17}{2}$

$\Rightarrow x\leqslant 8 \frac{1}{2}$

As the number of donuts can only be a natural number.

Hence, the maximum number of donuts that Jervane can buy are 8.
