What is the first step in solving the system by the substitution method?
x + 2y = 8
3x - 4y = 4
19
O Subtract 2y from cach side of x + 2y = 8
O Add x + 2y = 8 to 3x - 4y = 4
O Multiply x + 2y = 8 by-3
O Set x + 2y equal to 3x - 4y = 4

Answer:

Answer: 1.89 minutes

Step-by-step explanation: If we take 1 and 1/3 hours and turn that into minutes we get 80 minutes we then divide it by the number of miles 42 1/3. We would get about 1.89, so it took about 1.89 minutes

Answer:

62 cm^2

Step-by-step explanation:

the sides are 3*5, 3*2, and 2*5, and there are two of each. 3*5 is 15, 3*2 is 6, and 2*5 is 10.

we need to find 15*2, which is 30, 6*2, which is 12, and 10*2 which is 20. then we need to add all of these together, which is 62

Answer:

-7x/6-6=-48

-7x-36=-288

-7x=-288+36

x=-252/-7

x=36 answer

Answer:

a. 36

Step-by-step explanation:

Solve for x:

[tex] \longrightarrow [/tex] [tex] \sf - \dfrac{7}{6} x [/tex] - 6 = -48

Add 6 both sides:

[tex] \longrightarrow [/tex] [tex] \sf - \dfrac{7}{6} x [/tex] + (6 - 6) = -48 + 6

6 - 6 = 0

[tex] \longrightarrow [/tex] [tex] \sf - \dfrac{7}{6} x [/tex] = -48 + 6

-48 + 6 = -42

[tex] \longrightarrow [/tex] [tex] \sf - \dfrac{7}{6} x [/tex] = -42

Multiply both side by [tex] - \dfrac{6}{7} [/tex]:

[tex] \longrightarrow [/tex] [tex] \sf - \dfrac{7}{6} x \times \bigg(-\dfrac{6}{7} \bigg) = -42 \times \bigg(-\dfrac{6}{7} \bigg) [/tex]

[tex] \sf - \dfrac{7}{6} x \times \bigg(-\dfrac{6}{7} \bigg) = x: [/tex]

[tex] \longrightarrow [/tex] [tex] \sf x= -42 \times \bigg(-\dfrac{6}{7} \bigg) [/tex]

[tex] \sf -42 \times \bigg(-\dfrac{6}{7} \bigg) = 36: [/tex]

[tex] \longrightarrow [/tex] x = 36

Answer:

y= 8

Step-by-step explanation:

In a Triangle we know,

W+Y+X=180 degree

then,

(180-52)+(4y-4)+3y=180

or, 128+4y-4+3y= 180

or, 7y= 180- 124

or, y= 56/7

or, y= 8

hope you got it.

Step-by-step explanation:

Step-by-step explanation:

19.y+5=-12

y=-12-5

y=-17

x-y=10

x+17=10

x=10-17

x=-7

20.3x-5y=10

3*-7-5*-17=10

-21+85=10

64=10

10x+6y=-36

10*-7+6*-17=-36

-70+102=-36

32=-36

Answer:

5.4

Step-by-step explanation:

since they are 5 apart on the x-axis, and 2 on the y-axis. You'd multiply by the power of 2 add both of them together and square root. Giving you about 5.38516 rounding to the nearest tenth of 5.4

Answer:

The value of x is 3

Step-by-step explanation:

The stage is rectangular in shape.

The formula for area of a rectangle is:

Length × Width

Length = 24 feet

Width = 4x + 4 feet

Hence:

384 = (4x + 4) × (24)

384 = 96x + 96

Collect like terms

384 - 96 = 96x

288 = 96x

x = 288/96

x = 3

The value of x is 3

Answer:

Prob 150

Step-by-step explanation:

Answer:

Wanye can only bowl 4 times.

Step-by-step explanation:

the expression for this equation is

20 = 4.25x + 1.90

subtract  1.90 from both sides

18.10 = 4.25x

See how many times 4.25 can go into 18.10

1.) 18.10 - 4.25 = 13.85

2.) 13.85 - 4.25 = 9.60

3.) 9.60 - 4.25 = 5.35

4.) 5.35 - 4.25 = 1.1

1.1 < 4.25 so you can't subtract it

the answer is 4 times

Row 2: Yes, Yes, Yes

===============================

Explanation:

Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.

So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.
