$\frac{y - 1}{4} = -2 \\ \\ \frac{y - 1}{4} * 4 = -2 *4 \\ \\ y - 1 = -8 \\ \\ y - 1 +1 = -8 +1 \\ \\ y = -7$

Remember
you can do anything to an equation as long as you do it to both sides

and
a/b times b=a since b's cancel out
and
a-a=0
we hates fraction
times both sides by 4
4(y-1)/4=-8
4/4(y-1)=-8
1(y-1)=-8
y-1=-8
add 1
y+1-1=-8+1
y+0=-7
y=-7

The table shows the grade that 4 students received on a math test. Find the bar graph that represents the grades.

tiny-mole [99]

Answer:

The answer to your question is the first graph.

Step-by-step explanation:

It seems that the first graph is correct because the height of the bars is equal to the grade get by the students.

The second graph is incorrect because the height of the bars is different from the grade the students got. Only the bar of Levi is correct.

The third graph is incorrect, just observe the height of John's bar to determine that the graph is wrong.

Also, the last graph is incorrect, in this graph, all the bars are different from the grade the students got.

Solve the questions bellow

Hatshy [7]

Answer:

1. 29.67°

2. 68.96°

3. 89.85°

Step-by-step explanation:

1. Reference angle = x

Opposite = 45 cm

Adjacent = 79 cm

Therefore:

$tan(x) = \frac{45}{79}$

$tan(x) = 0.569620253$

$x = tan^{-1}(0.569620253)$

$x = 29.67$ (nearest hundredth)

2. Reference angle = B

Opposite = 14

Hypotenuse = 15

Therefore:

$sin(B) = \frac{14}{15}$

$sin(B) = 0.93333$

$B = sin^{-1}(0.93333)$

$B = 68.96$ (nearest hundredth)

3. Reference angle = x

Adjacent = 238,900 mi

Hypotenuse = 92,955,807 mi

Therefore:

$cos(x) = \frac{238,900}{92,955,807}$

$x = cos^{-1}(\frac{238,900}{92,955,807})$

$x = 89.85$ (nearest hundredth)

Please help with questions 1d and e

Aleksandr-060686 [28]

(d) $\frac{75}{2}$ , $\frac{75}{4}$ , $\frac{75}{8}$

(e) 68, 82, 96

(d) note that the terms have a common ratio ( r )

r = $\frac{300}{600}$ = $\frac{150}{300}$ = $\frac{1}{2}$

to obtain any term in the sequence, multiply the previous term by $\frac{1}{2}$

75 × $\frac{1}{2}$ = $\frac{75}{2}$

$\frac{75}{2}$ × $\frac{1}{2}$ = $\frac{75}{4}$

$\frac{75}{4}$ × $\frac{1}{2}$ = $\frac{75}{8}$

(e) note that the terms have a common difference (d )

d = 26 - 12 = 40 - 26 = 54 - 40 = 14

to obtain any term in the sequence, add 14 to the previous term

54 + 14 = 68

68 + 14 = 82

82 + 14 = 96
