Answer:

Step-by-step explanation:

let larger number be x and the other be y.

x - y = 18

x = 18+y

now, x + y = 116

therefore, 18+y+y= 116

18 + 2y =116

2y = 116-18

2y = 98

y = 98/2 = 49

larger number = 49 + 18 = 67

You need to solve a system of equations. You decide to use the elimination method. Which of these is not allowed? 3x-2y=7 equati

svetlana [45]

Answer:

x = 31/9 and y = 5/3

Step-by-step explanation:

It is given that,

3x - 2y = 7 -----(1)

3x + 4y = 17 ----(2)

To find the solution by elimination method

Step 1: Subtract eq(2) from eq(1)

3x - 2y = 7 -----(1)

3x + 4y = 17 ----(2)

0 - 6y = -10

6y = 10

y = 10/6 = 5/3

Step 2: Substitute the value of y in eq (1)

3x - 2y = 7 -----(1)

3x - 2*(5/3) = 7

3x = 7 + 10/3

3x = 31/3

x = 31/9

Therefore x = 31/9 and y = 5/3

Find the slope of the line that passes through (4,2) and (9,1)?

pshichka [43]

Answer:

The slope of the line is $\displaystyle -\frac{1}{5}$ .

Step-by-step explanation:

We are given two coordinate points:

$(4, 2)$
$(9, 1)$

We are asked to find the slope of the line.

We can use the rise-over-run formula to solve for the slope of the line.

$\displaystyle \text{slope} = \frac{\text{rise}}{\text{run}}\\\\\text{slope} = \frac{y_2-y_1}{x_2-x_1}$

However, we firstly need to name our coordinate points.

In math, we can label our coordinates using the following label system:

$(x_1, y_1), (x_2, y_2)$

Therefore, we can also label our coordinates as such:

$x_1 = 4$
$y_1 = 2$
$x_2 = 9$
$y_2 = 1$

Now, we can supply these values into the formula and solve for our slope, or a better known variable, m.

$\displaystyle m = \frac{1 - 2}{9 - 4}\\\\m = \frac{-1}{5}\\\\m = -\frac{1}{5}$

Therefore, our slope is $\displaystyle -\frac{1}{5}$ .

How do I solve 4^-3? ( four to the power of negative three)

Liono4ka [1.6K]

4^-3

You first need to make the exponent positive. To do this put it in a fraction.

1/4^3

Now solve the exponent.

4 * 4 * 4 =
^
16*4 = 64

1/64 is your answer
