If Oliver made 10% more than he usually makes, he would not have $520 in his savings.

520 × 10% = 52

520 + 52 = 572

10% × 572 = 57.20

572 - 57.20 = 514.80

Oliver would have $57.20 saved. So, he would have $514.80 left to spend. Instead of adding 10% to his usual earnings, Oliver multiplied his earning by 10, falsely concluding that his spending money would be higher than what it actually is.

Find the equation of a line that passes through these two points
Sati [7]

Answer:

y = -2x + 2

Step-by-step explanation:

The equation of a line is y = mx + b.

First we want to find m, the slope. We can used the coordinates to do so: m = \frac{6-(-4)}{-2-3}\\m = \frac{10}{-5}\\m = -2

Now we know that the equation is y = -2x + b. We can plug in the coordinate (3, -4) to find b.

y = -2x + b\\-4 = -2(3) + b\\-4 = -6 + b\\b = 2

So the equation is y = -2x + 2.

Will mark BRAINLIEST!! — Point H is the circumcenter of triangle DEF. Which must be true? Check ALL that apply. See image.
Margarita [4]

Answer:

A, C, F

Step-by-step explanation:

Definition: The circumcenter is  the center of the triangle's circumcircle - the circle that passes through all three of the triangle's vertices. If point H is the circumcenter of the triangle DEF, then the circumcircle passes through its vertices D, E and F (option A is true).

Option B is false, the circumcircle doesn't pass through the points L, M and N. This option is true for inscribed circle, not for circumcircle.

Option C is true, because HD and HE are the radii of the circumcircle.

Option D is false. This option is true for inscribed circle, not for circumcircle.

Option E is false. This option is true for inscribed circle, not for circumcircle.

Option F is true, because both these angles are right angles.

Write and solve a system of linear equations: The larger of two numbers is 18 more than 5 times the smaller. If 3 times the larg
marshall27 [118]

Answer:

8 and -2

Step-by-step explanation:

Let the numbers be l and s.

We have equations:

l = 5s + 18

3l + 4s = 16

Solve for s by substituting l into the second equation:

3(5s + 18) + 4s = 16

15s + 54 + 4s = 16

19s = 16 - 54

19s = -38

s = -38/19

s = -2

Find the value of l:

l = 5(-2) + 18

l = -10 + 18

l = 8
