I dont think so but to justify quads means four and the is no sign of x to the fourth power or y to the fourth power ect.

No, it's liner function
y=x
(Would be just a straight line the graph, not parabola)

write the correct Equation and Solve. Use x for the variable. The difference of four times a number and seven is thirteen

Verizon [17]

Answer:

Step-by-step explanation:

Let the number be x

4times a number =4x

The difference of four times a number and seven : 4x - 7

4x - 7 = 13

4x = 13 + 7

4x = 20

x = 20/4

x = 5

Find the values of x and y. The diagram is not to scale.

Aleksandr [31]

Step 1

Find the value of x

we know that

$(x-1)\°=74\°$ -------> by corresponding angles, because the given lines are parallel

Solve for x

$(x-1)\°=74\°\\x=74+1 \\ x=75\°$

Step 2

Find the value of y

we know that

$(x-1)+40+(y-2)=180$

substitute the value of x and solve for y

$(75-1)+40+(y-2)=180$

$74+40-2+y=180$

$112+y=180$

$y=180-112$

$y=68\°$

therefore

the answer is the option B

$x=75\°, y=68\°$

Find the slope of the line that passes through (-37, 47) and (26, 32).

stiks02 [169]

(x1,y1) = (-37,47)
(x2,y2) = (26,32)

Now, m = (47-32) / (26+37)
m = 15 / 63
m = 5/21
So, the slope would be 5/21

Hope this helps!
