Answer:
A. y=x+7

Explanation:
All of the answers are in y-intercept form (y=mx+b where m is the slope and b is the y-intercept), so the two points are used to solve for slope and y-intercept. Immediately, (0,7) gives the y-intercept because this point intercepts the y-axis at 7. Slope is found by dividing the rise over run between the two points. The points rise in y from 2 to 7 for a total of 5 units and the points run from -5 to 0 for a total of 5 units. Rise divided by run would be 5/5, simplified to a slope of 1. From this, slope=m=1 and y-intercept=b=7. Plugging these values into y=mx+b, the final answer is y=x+7.

C and ​ ∠D ​ are vertical angles with m∠C=−x+26 and m∠D=2x−10 . What is m∠D ? Enter your answer in the box. ​ °
ANEK [815]
Angle c and angle d are congruent. Congruent means they have the same the measure, or they have EQUAL measures. You set the two values equal to each other and solve for x.
X+26=2x-10 subtract x from both sides
26=x-10 add 10 to both sides
36=x

Now substitute x back in for angle d.
2(36)-10 = 62

Landry earned $2,300 over the summer and decided to invest it in an account that earns 4% annual compound interest. If Landry do
solniwko [45]

Answer:

Landry will have $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = once per year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :) the equations aren't showing up right :(

Jake earns $12 for each hour worked. The equation y = 12x can be used to model this situation, where x represents the number of
Pavlova-9 [17]

Answer: y is the dependent variable

Step-by-step explanation:

In mathematics, a function is a rule for taking an input and providing an output.

A symbol that stands for an arbitrary input is called an independent variable.

A symbol that stands for an output that depends on the value of a independent variable is called a dependent variable.

y = 12x  } Function

x is the independent variable = arbitrary number of hours worked.

y is the dependent variable because depends on the value of x.
