Write the equation of a line perpendicular to 8x - 7y= -6 that passes through the point (-8,6).
The equation of the line is y=

​

Answers

Answer:

y= -7/8x – 1

Step-by-step explanation:

the first equation would be y= 8/7 + 6/7the perpendicular slope would be -8/7and I solved for b by plugging in what I know for y=mx+bwhich is 6= -7/8(-8) + bsimplify so 6 = 7 + bsubtract 7 on both sides to get b = -1

y = -4x – 5
y = -2x + 10 solve using substitution show work please

Answers

Answer:

(- [tex]\frac{15}{2}[/tex], 25 )

Step-by-step explanation:

Given the 2 equations

y = - 4x - 5 → (1)

y = - 2x + 10 → (2)

Substitute y = - 2x + 10 into (1)

- 2x + 10 = - 4x - 5 ( add 4x to both sides )

2x + 10 = - 5 ( subtract 10 from both sides )

2x = - 15 ( divide both sides by 2 )

x = - [tex]\frac{15}{2}[/tex]

Substitute this value into either of the 2 equations and evaluate for y

Substituting into (2)

y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25

Solution is ( - [tex]\frac{15}{2}[/tex], 25 )

necessary, round your answer to the nearest
hundredth.
A 0.28
© 0.5
B 0.18
D 0.09

Answers

Answer:

0.18

Step-by-step explanation:

9/50 is the same as 18/100, we know this because if we multiply both 9 and 50 by 2, it gives us 18/100. 18/100 can be turned into the decimal, 0.18, so your answer is 0.18

Answers

Answer:

A. x ≥ -3 and x < 2, or -3 ≤ x < 2

Step-by-step explanation:

Remember solid dot means include, open dot means not include.

x ≥ -3: this means x is greater and equal (includes) -3.

x < 2: this means x is less than 2 and does not include it.

Answer:

A

Step-by-step explanation:

So on the number line you see a closed circle at -3 and an open circle at 2.

Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.

So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].

The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].

To combine it together, it would get [tex]-3 \geq x < 2[/tex].

Since option A is [tex]x \geq -3[/tex] and  [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.

Hoped this helped! If not, please let me know and I'll try to explain more! <3

Solve the inequality and complete a line graph representing the solution. In a minimum of two sentences, describe the solution and the line graph.

To get the solution you would first isolate the variable by subtracting five from both sides. To get three is greater or equal to three X then you would divide three by three to get one. Then you would plot that in a line graph by placing a closed dot on one which represents x is equal to or less than 1. Then you make an arrow pointing left because x is less than or equal to 1.

Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account. What is Mr. Smith's account balance now? *

Answers

Answer:

$  263.42

Step-by-step explanation:

-275.78 + 539.20 = 263.42

The new balance in Mr. smith account will be $263.42.

What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account.

Assume that the new amount in his account will be [x]. Then -

[x] = 539.20 - 275.78

[x] = 263.42

Therefore, the new balance in Mr. smith account will be $263.42.
