how to solve this math problem​

Answer: C, a = 250t + 500

Step-by-step explanation: First, we can simply take out 500 out of 1500 to show the first deposit. Now we can do 1000 / 4 to get 250 a month.

This gives us a = 250t + 500

Hope this helps :)

Step-by-step explanation:

The chords, when cut anywhere along their length so that there is one intersection point, will produce the following relationship for this question.

(w + 6)*4 = 16*10       Remove the brackets

4*w + 24 = 160         Subtract 24 from both sides

4w = 160 - 24           Combine the right

4w = 136                   Divide by 4

w = 136/4

w = 34

Given:

Consider the below figure attached with this question.

[tex]m\angle 3=(x+30)^\circ[/tex] and [tex]m\angle 4=(2x-80)^\circ[/tex].

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

[tex]m\angle 3=m\angle 4[/tex]

[tex](x+30)^\circ=(2x-80)^\circ[/tex]

[tex]x+30=2x-80[/tex]

[tex]x-2x=-30-80[/tex]

[tex]-x=-110[/tex]

[tex]x=110[/tex]

Now,

[tex]m\angle 3=(110+30)^\circ[/tex]

[tex]m\angle 3=140^\circ[/tex]

Therefore, the measure of angle 3 is 140 degrees.

Answer:

y = -3x + 2

Step-by-step explanation:

The linear equation is in the form

y = mx + b

where m is the slope and b is the y-intercept

the slope can be calculated using two points

Let us have; (-2,8) and (0,2)

The equation of the slope is ;

m = (y2-y1)/(x2-x1) = (2-8)/(0+2) = -6/2 = -3

So for the y-intercept, we select any of the points to substitute

Let us have (0,2)

Substitute this into;

y = -3x + b

2 = -3(0) + b

b = 2

So the equation is;

y = -3x + 2

could you posibly put a pic

Step-by-step explanation:

Answer:

1 = Given

2 = Given

3 = Substitution Property

4 = Distributive Property

5 = Given

6 = Substitution Property

7 = Simplify

8 = Subtraction Property

9 = Addition Property

By substituting given c and d values inn the given equation and simplifying we get a=b. Hence, proved.

Given that, 2c =d-2b, c = a-b and d= a + b.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

To prove: d=a+b

Proof:

1. 2c =d-2b (Given)

2. c=a-b (Given)

3. 2(a-b)=d-2b (Substitute c=a-b)

4. 2a-2b=d-2b

5. d=a+b (Given)

6. 2a-2b=a+b-2b (Substitute d=a+b)

7. 2a-2b=a-b

8. a-2b=-b (Transpose a to LHS and simplify)

9. a=b (Transpose a to RHS and simplify)

By substituting given c and d values inn the given equation and simplifying we get a=b. Hence, proved.

Answer:

Option C

Step-by-step explanation:

[tex]\frac{7x-3}{9} \geq 8-2x\\\\7x-3\geq 9(8-2x)\\\\7x-3\geq 72-18x\\\\7x+18x\geq 72+3\\\\25x\geq 75\\\\x\geq 3[/tex]

Option A and Option C are almost same but if we look close Option A has an open circle dot on x = 3 where as Option C has a closed circle which means that small circle at x = 3 is colored that represents [tex]x\geq 3[/tex]

Answer:

the third option is the answer, y= 1/4x-1

Step-by-step explanation:

graph line in standard form:

[tex]y = mx + c[/tex]

where m = slope and c = y-intercept

1) find the slope

slope formula:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

use the two coordinates given in the graph

i/ (0,-1)

x1 = 0

y1 = -1

ii/ (4,0)

x2 = 4

y2 = 0

substitute the values into the formula

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]

[tex] \frac{1}{4} [/tex]

thus, m = 1/4

2) find the y-intercept

* y-intercept is the value of y that cuts through the y-axis

based on the graph, the y-intercept is -1

thus, c = -1

3) substitute the value of m and c into the standard form formula

[tex]y = mx + c[/tex]

[tex]y = \frac{1}{4} x - 1[/tex]
