Choose the correct translation of the following statement into symbolic form using the uppercase letters available. If neither w
Over [174]

Answer:

¬(W∨S)→¬(J∨E)

D→(B∨C)

X is true

No

Step-by-step explanation:

The hypotheses  "neither water nor soft drinks can quench your thirst" translates to ¬(W∨S) ("neither nor" negates the disjunction W∨S). The "if,... then" translates to the implication symbol (arrow). The conclusion "juice will not do it, unless the juice contains electrolytes" translates to ¬(J∨E). This is because if J or E were true, then J would be true (because E implies J), contrary to the conclusion that J is false ("juice will not do it"), then J∨S is false.

The hypothesis here is "the dyer breaks" hence D is the hypothesis. The conclusion is "we will hang the clothes to dry, or take the clothes to a coin-operated laundry" which is the same as (B∨C).

The proposition p→p is always true (according to truth tables). In this case, p:=X is true, then p is true and X is true.

X∨Y is false if and only if X is false and Y is false, so both statements X,Y must be false.

What is the equation of a line with a x-intercept of −2 and a y-intercept of 10?
IceJOKER [234]

Hey there! :)

Answer:

y = 5x + 10

Step-by-step explanation:

From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

Plug in the points:

m= \frac{10 - 0}{0 - (-2)}

Simplify:

m= \frac{10}{2}

m = 5.

The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:

y = 5x + 10 is the equation written in slope-intercept form.

Find the area of the figure.
Vesnalui [34]

Answer:

AREA = 4,850

Step-by-step explanation:

split into two pieces  

formula for triangles- base x height divided by 2

20 x 50 = 100 / 2 = 50

(130 - 50 = 80)

80 x 120 = 9,600 / 2 = 4,800

add...

4,800 + 50 = 4,850

Braxton and Maggie babysit children for extra money over the summer. Braxton's income is determined by f(x) = 9x + 10, where x i
Galina-37 [17]
Lets say that Maggie works 5 hours just the same as Braxton. if we use h(x)=f(x)+g(x) they would make about $100 combined. having to split that Braxton would make less then what he originally. since 9(5)+10= 55 and 6(5)+15=45. but if say Maggie works more then 5 hours then Braxton will be more money then just working alone.
