Answer:

Step-by-step explanation:

4d + 7e = 68

-4d - 6e = -72

e = -4

4d + 7(-4) = 68

4d - 28 = 68

4d = 96

d = 24

(24, -4)

Solve the system. 2x + y = −3 −2y = 6 + 4x Write each equation in slope-intercept form.

Fantom [35]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

-------------------------------------

2x + y = -3 subtract 2x from both sides

y = -2x - 3

-2y = 6 + 4x

-2y = 4x + 6 divide both sides by (-2)

y = -2x - 3

We have the same equations. Therefore the system of equations is dependent. Has an infinite number of solutions

x ∈ R

y = -2x - 3

Find the outputs for a given function using these input values: x: Input -10, 0, ,2 , 4, 10 Function Rule f(x) = -x+2 -10 0 2 4

raketka [301]

Answer:

12, 2, 0, -2 and 8

Step-by-step explanation:

Give the function f(x) = -x+2

If x = -10

y = -(-10)+2

y = 10+2

y = 12

If x = 0

y = -0+2

y = 2

If x = 2

y = -2+2

y = 0

If x = 4

y = -4+2

y = -2

If x = 10

y = -10+2

y = -8

Hence the outputs are 12, 2, 0, -2 and 8

The table shows the results of a survey in which 10th-grade students were asked how many siblings (brothers and/or sisters) they

lesantik [10]

Answer:

70%

Step-by-step explanation:

Given

Number of Siblings: || 0 || 1 || 2 || 3

Number of Students: || 4 || 18 || 10 || 8

Required

Determine the probability of a student having at least one but not more than 2 siblings

First, we have to determine the total number of 10th grade students

$Total = 4 + 18 + 10 + 8$

$Total = 40$

The probability of a student having at least one but not more than 2 siblings = P(1) + P(2)

Solving for P(1)

P(1) = number of students with 1 sibling / total number of students

From the given parameters, we have that:

Number of students with 1 sibling = 18

So:

$P(1) = \frac{18}{40}$

Solving for P(2)

P(2) = number of students with 2 siblings / total number of students

From the given parameters, we have that:

Number of students with 2 siblings = 10

So:

$P(2) = \frac{10}{40}$

$P(1) + P(2) = \frac{18}{40} + \frac{10}{40}$

Take LCM

$P(1) + P(2) = \frac{18 + 10}{40}$

$P(1) + P(2) = \frac{28}{40}$

Divide numerator and denominator by 4

$P(1) + P(2) = \frac{7}{10}$

$P(1) + P(2) = 0.7$

Convert to percentage

$P(1) + P(2) = 70\%$

Hence, the required probability is 70%
