solve 2x + -3 = -23 algebraically

Answer:

Slope = -5/4

y-intercept = 7

Step-by-step explanation:

The equation is y = mx + b.

m is the slope, while b is the y-intercept.

Because -5/4 is where m would be in the equation, it is the slope.

7 is where b would be in the equation, so it is the y-intercept.

Answer:

Arithmetic progression is a series of numbers in which each one varies from the one before it by a constant quantity

Geometric progression is a non-zero number sequence in which each term after the first is found by multiplying the previous term by a fixed, non-zero number known as the common ratio.

Answer:

35/37

Step-by-step explanation:

In this question, we are to calculate the ratio that represents the cosine of angle O

Firstly, please check the attachment for the diagram of the triangle.

Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse

The hypotenuse is the longest length which is 37 which represents the length ON

The side adjacent to angle O is the side OP which is 35

Thus, the ratio representing the cosine of angle O is 35/37

Answer:

5.7 pints

Step-by-step explanation:

Total pints of paint used = 9.5 pints

Fraction of blue paint used = 2/5 ; while the rest is white paint

Amount od blue paint used :

2/5 * 9.5 = 3.8 pints

Amount of white paint used :

Total pints - blue pints used

9.5 pints - 3.8 pints

= 5.7 pints of white paint.

Answer:

78.54

Step-by-step explanation:

The area of a circle can be found using

[tex]A=\pi r^2[/tex]

If we know that the radius is 5, then our equation becomes this.

[tex]A=\pi*5^2[/tex]

Simplifying:

[tex]A=3.14*25[/tex]

Gives us:

[tex]A=78.54[/tex]

Answer:

A

Step-by-step explanation:

if x=19, 19x3 =57 and 57+123=180 and straight angle = 180 so A

Answer:

X=19

Step-by-step explanation:

123 and 3x are supplementary/they equal 180 added together.

Let's solve your equation step-by-step.

123+3x=180

Step 1: Simplify both sides of the equation.

3x+123=180

Step 2: Subtract 123 from both sides.

3x+123−123=180−123

3x=57

Step 3: Divide both sides by 3.

3x/3 = 57/3

x=19

Have a splendid day.

Answer:

Marco had been saving for 367 days.

Step-by-step explanation:

If Marco started with no money and put $0.25 into a jar a day, then you just have to divide the total amount of money he has by 0.25.

91.75/.25 = 367

Answer: -5x+y=6

Step-by-step explanation:

Given

Points on line [tex](-1,1)\ \text{and}\ (0,6)[/tex]

The standard form of an equation is [tex]ax+by=c[/tex]

Using the two-point form of a line

[tex]\Rightarrow \dfrac{y-1}{x+1}=\dfrac{6-1}{0+1}\\\Rightarrow \dfrac{y-1}{x+1}=\dfrac{5}{1}\\\Rightarrow y-1=5x+5\\\Rightarrow y-5x=6\\\Rightarrow -5x+y=6[/tex]

Answer:

It is correct actually.

Step-by-step explanation:

141 + 39 = 180

Yeah, that's correct

Explanation: Supplementary angles add to 180 degrees. If angle R is 39 degrees then angle S has to be 141 degrees because 39 + 141 = 180.

Answer:

A. 0.5J

Step-by-step explanation:

[tex]K. E._{(cart)} = \frac{1}{2} m {v}^{2} \\ \\K. E._{(cart)} = \frac{1}{2} \times 4 \times (0.5)^{2} \\ \\ K. E._{(cart)} = 2 \times 0.25 \\ \\ K. E._{(cart)} = 0.5 \: J[/tex]

The kinetic energy of a 4 kg cart pushed at a rate of 0.5 m/s is 0.5 J.

Kinetic energy = 1 /2 mv²

where

m = mass

v = velocity

Therefore,

m = 4 kg

v = 0.5

Kinetic energy = 1 / 2 × 4 × 0.5²

kinetic energy = 1 / 2 × 4 × 0.25

kinetic energy = 1 / 2 × 1

kinetic energy =  1 /2  = 0.5 j

Answer:

b = 6

Step-by-step explanation:

Pythagorean formula:

a² + b² = c²

Width of box, W = 5 inches

Width of marker to be stored in box = 1/2 inch

The number of 1/2 inch marker which can be stored in box is :

Width of box ÷ width of marker to be stored in box

5 inches ÷ 1/2 inches

5 / 0.5

= 10

Answer:

d) y = -1/2 + 3

Step-by-step explanation:

Looking at the graph, we can use y = mx + b to find the equation. m is the slope and for slope, we go 1 unit down and 2 units to the right. b is the y variable and our b would be 3.

y = mx + b

y = -1/2x + 3
