look at the graph

for 47. it's asking when the input (aka the X) is equal to 1, what is the output (aka the Y). so just go to the graph where X=1 and read the Y

Answer:

rearrange the question

y - 5x = 8.................(1)

y - 8x = 9..................(2)

make y the subject formula in eqn. (1)

y = 8 + 5x................(3)

substitute

8 + 5x - 8x = 9

-3x = 1

x = -⅓

y = 8 + 5x

y = 8 + (-⅓)

y = 23/3

Answer:

y = 80x + 5000

Step-by-step explanation:

Hello There!

y-y1=m(x-x1)

y-1=m(x-2)                       [tex]m=\frac{y2-y1}{x2-x1}[/tex]

Step-by-step explanation:

To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.

1. 29.68 / 4 = 7.42

So $7.42 is the unit price.

2. 625 / 6 = 104 (rounded to the nearest whole number)

So Jess can type 104 words per minute.

Answer:

1. 7.24

2. 104

Step-by-step explanation:

1. divide 29.68 by 4

> 29.68÷4

> 7.24

therefore the unit price is 7.24

check: 7.24x4=29.68

2. divide 625÷6

> 625÷6

> 104.1666667

> 104.1666667 round off 104

therefore he can type 104words per minute

Answer:

x = 18.75 Round to nearest tenth is 18.8

Step-by-step explanation:

We have, 80% × x = 15

or,  [tex]\frac{80}{100}[/tex]  × x = 15

Multiplying both sides by 100 and dividing both sides by 80,

we have x = 15 × [tex]\frac{100}{80}[/tex]

x = 18.75

If you are using a calculator, simply enter 15×100÷80, which will give you the answer.

Have a blessed day

The difference between the high temperature and the low temperature is 24.3 F.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the high temperature was recorded as 19.8°F. The low temperature that same day was recorded as −4.5°F.

The difference will be calculated as,

D = High temperature - low temperature

D = 19.8 - (-4.5)

D = 24.3 F

Therefore, the difference between the high temperature and the low temperature is 24.3 F.

Step-by-step explanation:

that is the only one with the right numbers

Step-by-step explanation:

63+36+X = 180 (interior angles of a triangle equal 180)

X = 180-99

X= 81

X+Z= 180(angles on a straight line adds up to 180)

81+y= 180

Z=180-81

Z =99

13+Z+Y=180

13+99+Y=180

Y=180-112

Y=68

Answer:

Step-by-step explanation:

Surface Area of a cylinder = 2 × area of base + lateral face

First find the area of the base

Area of Base = πr² ( pi × radius squared ) ( pi = 3.14 )

AB = 3.14 × 3²

AB = 3.14 × 9

Area of Base = 28.26

Next, find the lateral face

Lateral Face = circumference of base × altitude

( circumference of base = 2πr ) ( altitude = height of the cylinder )

LF = 2 × 3.14 × 3

Lateral Face = 18.84

Last, is the Surface Area

Surface Area of a cylinder = 2 × area of base + lateral face (formula)

SA = 2 × 28.26 + 18.84 × 5

SA = 56.52 + 18.84 × 5

SA = 56.52 + 94.2

Answer:

Step-by-step explanation:

So first of all, you can rearrange your equations:

4x + 7x = 11 can be rearranged and simplified to x = 11/7

x = y + 1 can be rearranged to y = x - 1

Then you can graph them like normal by plugging in points. It should look like the following picture

Note the rule

[tex]\\ \tt\longmapsto a_3=3(-1/2)^{3-1}=3(-1/2)^2=-3/4[/tex]
